(What is this?)
Only physicians experienced in management of systemic immunosuppressive therapy for the indicated disease should prescribe Cyclosporine Capsules USP MODIFIED. At doses used in solid organ transplantation, only physicians experienced in immunosuppressive therapy and management of organ transplant recipients should prescribe Cyclosporine Capsules USP MODIFIED. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient.
Cyclosporine Capsules USP MODIFIED, a systemic immunosuppressant, may increase the susceptibility to infection and the development of neoplasia. In kidney, liver, and heart transplant patients Cyclosporine Capsules USP MODIFIED may be administered with other immunosuppressive agents. Increased susceptibility to infection and the possible development of lymphoma and other neoplasms may result from the increase in the degree of immunosuppression in transplant patients.
Cyclosporine Capsules USP MODIFIED has increased bioavailability in comparison to Sandimmune® (Cyclosporine Capsules USP). Cyclosporine Capsules USP MODIFIED and Sandimmune® (Cyclosporine Capsules USP) are not bioequivalent and cannot be used interchangeably without physician supervision. For a given trough concentration, cyclosporine exposure will be greater with Cyclosporine Capsules USP MODIFIED than with Sandimmune® (Cyclosporine Capsules USP). If a patient who is receiving exceptionally high doses of Sandimmune® (Cyclosporine Capsules USP) is converted to Cyclosporine Capsules USP MODIFIED, particular caution should be exercised. Cyclosporine blood concentrations should be monitored in transplant and rheumatoid arthritis patients taking Cyclosporine Capsules USP MODIFIED to avoid toxicity due to high concentrations. Dose adjustments should be made in transplant patients to minimize possible organ rejection due to low concentrations. Comparison of blood concentrations in the published literature with blood concentrations obtained using current assays must be done with detailed knowledge of the assay methods employed.
For Psoriasis Patients (see also Boxed WARNINGS above)
Psoriasis patients previously treated with PUVA and to a lesser extent, methotrexate or other immunosuppressive agents, UVB, coal tar, or radiation therapy, are at an increased risk of developing skin malignancies when taking Cyclosporine Capsules USP MODIFIED.
Cyclosporine, the active ingredient in Cyclosporine Capsules USP MODIFIED, in recommended dosages, can cause systemic hypertension and nephrotoxicity. The risk increases with increasing dose and duration of cyclosporine therapy. Renal dysfunction, including structural kidney damage, is a potential consequence of cyclosporine, and therefore, renal function must be monitored during therapy.
Cyclosporine Capsules USP MODIFIED is an oral formulation of cyclosporine that immediately forms an emulsion in an aqueous environment.
Cyclosporine, the active principle in Cyclosporine Capsules USP MODIFIED, is a cyclic polypeptide immunosuppressant agent consisting of 11 amino acids. It is produced as a metabolite by the fungus species Mycelium sterilae.
Chemically, cyclosporine is designated as [R-[R*,R*-(E)]]-cyclic-(L-alanyl-D-alanyl-N-methyl-L-leucyl-N-methyl-L-leucyl-N-methyl-L-valyl-3-hydroxy-N,4-dimethyl-L-2-amino-6-octenoyl-L-α-amino-butyryl-N-methylglycyl-N-methyl-L-leucyl-L-valyl-N-methyl-L-leucyl) and has the following structural formula:
Each soft gelatin capsule for oral administration contains either 25 mg, 50 mg or 100 mg of Cyclosporine USP MODIFIED and 18.6% v/v (14.7% wt/vol) dehydrated alcohol and has the following inactive ingredients: DL-alpha-tocopherol, FD&C blue #2 aluminum lake, gelatin, glycine, glycerol 85%, polyoxyl 40 hydrogenated castor oil, polyglycerol (3) oleate, polyglycerol (10) oleate, sorbitol solution and titanium dioxide. In addition, the 25 mg and 50 mg contains ferric oxide (yellow) and the 100 mg contains ferric oxide (brown).
Cyclosporine is a potent immunosuppressive agent that in animals prolongs survival of allogeneic transplants involving skin, kidney, liver, heart, pancreas, bone marrow, small intestine, and lung. Cyclosporine has been demonstrated to suppress some humoral immunity and to a greater extent, cell-mediated immune reactions such as allograft rejection, delayed hypersensitivity, experimental allergic encephalomyelitis, Freund’s adjuvant arthritis, and graft vs. host disease in many animal species for a variety of organs.
The effectiveness of cyclosporine results from specific and reversible inhibition of immunocompetent lymphocytes in the G0- and G1-phase of the cell cycle. T-lymphocytes are preferentially inhibited. The T-helper cell is the main target, although the T-suppressor cell may also be suppressed. Cyclosporine also inhibits lymphokine production and release including interleukin-2.
No effects on phagocytic function (changes in enzyme secretions, chemotactic migration of granulocytes, macrophage migration, carbon clearance in vivo) have been detected in animals. Cyclosporine does not cause bone marrow suppression in animal models or man.
The immunosuppressive activity of cyclosporine is primarily due to parent drug. Following oral administration, absorption of cyclosporine is incomplete. The extent of absorption of cyclosporine is dependent on the individual patient, the patient population, and the formulation. Elimination of cyclosporine is primarily biliary with only 6% of the dose (parent drug and metabolites) excreted in urine. The disposition of cyclosporine from blood is generally biphasic, with a terminal half-life of approximately 8.4 hours (range 5 to 18 hours). Following intravenous administration, the blood clearance of cyclosporine (assay: HPLC) is approximately 5 to 7 mL/min/kg in adult recipients of renal or liver allografts. Blood cyclosporine clearance appears to be slightly slower in cardiac transplant patients.
The Cyclosporine Capsules USP MODIFIED and Cyclosporine Oral Solution USP MODIFIED are bioequivalent.
The relationship between administered dose and exposure (area under the concentration versus time curve, AUC) is linear within the therapeutic dose range. The intersubject variability (total, %CV) of cyclosporine exposure (AUC) when Cyclosporine Capsules USP MODIFIED or Sandimmune® (Cyclosporine Capsules USP) is administered ranges from approximately 20% to 50% in renal transplant patients. This intersubject variability contributes to the need for individualization of the dosing regimen for optimal therapy (see DOSAGE AND ADMINISTRATION). Intrasubject variability of AUC in renal transplant recipients (%CV) was 9% to 21% for Cyclosporine Capsules USP MODIFIED and 19% to 26% for Sandimmune® (Cyclosporine Capsules USP). In the same studies, intrasubject variability of trough concentrations (%CV) was 17% to 30% for Cyclosporine Capsules USP MODIFIED and 16% to 38% for Sandimmune® (Cyclosporine Capsules USP).
Cyclosporine Capsules USP MODIFIED has increased bioavailability compared to Sandimmune® (Cyclosporine Capsules USP). The absolute bioavailability of cyclosporine administered as Sandimmune® (Cyclosporine Capsules USP) is dependent on the patient population, estimated to be less than 10% in liver transplant patients and as great as 89% in some renal transplant patients. The absolute bioavailability of cyclosporine administered as Cyclosporine Capsules USP MODIFIED has not been determined in adults. In studies of renal transplant, rheumatoid arthritis and psoriasis patients, the mean cyclosporine AUC was approximately 20% to 50% greater and the peak blood cyclosporine concentration (Cmax) was approximately 40% to 106% greater following administration of Cyclosporine Capsules USP MODIFIED compared to following administration of Sandimmune® (Cyclosporine Capsules USP). The dose normalized AUC in de novo liver transplant patients administered Cyclosporine Capsules USP MODIFIED 28 days after transplantation was 50% greater and Cmax was 90% greater than in those patients administered Sandimmune® (Cyclosporine Capsules USP). AUC and Cmax are also increased (Cyclosporine Capsules USP MODIFIED relative to Sandimmune® (Cyclosporine Capsules USP)) in heart transplant patients, but data are very limited. Although the AUC and Cmax values are higher on Cyclosporine Capsules USP MODIFIED relative to Sandimmune® (Cyclosporine Capsules USP), the pre-dose trough concentrations (dose-normalized) are similar for the two formulations.
Following oral administration of Cyclosporine Capsules USP MODIFIED, the time to peak blood cyclosporine concentrations (Tmax) ranged from 1.5 to 2 hours. The administration of food with Cyclosporine Capsules USP MODIFIED decreases the cyclosporine AUC and Cmax. A high fat meal (669 kcal, 45 grams fat) consumed within one-half hour before Cyclosporine Capsules USP MODIFIED administration decreased the AUC by 13% and Cmax by 33%. The effects of a low fat meal (667 kcal, 15 grams fat) were similar.
The effect of T-tube diversion of bile on the absorption of cyclosporine from Cyclosporine Capsules USP MODIFIED was investigated in eleven de novo liver transplant patients. When the patients were administered Cyclosporine Capsules USP MODIFIED with and without T-tube diversion of bile, very little difference in absorption was observed, as measured by the change in maximal cyclosporine blood concentrations from pre-dose values with the T-tube closed relative to when it was open: 6.9±41% (range -55% to 68%).

Cyclosporine is distributed largely outside the blood volume. The steady state volume of distribution during intravenous dosing has been reported as 3 to 5 L/kg in solid organ transplant recipients. In blood, the distribution is concentration dependent. Approximately 33% to 47% is in plasma, 4% to 9% in lymphocytes, 5% to 12% in granulocytes, and 41% to 58% in erythrocytes. At high concentrations, the binding capacity of leukocytes and erythrocytes becomes saturated. In plasma, approximately 90% is bound to proteins, primarily lipoproteins. Cyclosporine is excreted in human milk (see PRECAUTIONS, Nursing Mothers).
Cyclosporine is extensively metabolized by the cytochrome P-450 3A enzyme system in the liver, and to a lesser degree in the gastrointestinal tract, and the kidney. The metabolism of cyclosporine can be altered by the coadministration of a variety of agents (see PRECAUTIONS, Drug Interactions). At least 25 metabolites have been identified from human bile, feces, blood, and urine. The biological activity of the metabolites and their contributions to toxicity are considerably less than those of the parent compound. The major metabolites (M1, M9, and M4N) result from oxidation at the 1-beta, 9-gamma, and 4-N-demethylated positions, respectively. At steady state following the oral administration of Sandimmune® (Cyclosporine Capsules USP), the mean AUCs for blood concentrations of M1, M9 and M4N are about 70%, 21%, and 7.5% of the AUC for blood cyclosporine concentrations, respectively. Based on blood concentration data from stable renal transplant patients [13 patients administered Cyclosporine Capsules USP MODIFIED and Sandimmune® (Cyclosporine Capsules USP) in a cross-over study], and bile concentration data from de novo liver transplant patients (4 administered Cyclosporine Capsules USP MODIFIED; 3 administered Sandimmune® (Cyclosporine Capsules USP)), the percentage of dose present as M1, M9, and M4N metabolites is similar when either Cyclosporine Capsules USP MODIFIED or Sandimmune® (Cyclosporine Capsules USP) is administered.
Only 0.1% of a cyclosporine dose is excreted unchanged in the urine. Elimination is primarily biliary with only 6% of the dose (parent drug and metabolites) excreted in the urine. Neither dialysis nor renal failure alter cyclosporine clearance significantly.
(See PRECAUTIONS, Drug Interactions)
When diclofenac or methotrexate was coadministered with cyclosporine in rheumatoid arthritis patients, the AUC of diclofenac and methotrexate, each was significantly increased (see PRECAUTIONS, Drug Interactions). No clinically significant pharmacokinetic interactions occurred between cyclosporine and aspirin, ketoprofen, piroxicam, or indomethacin.
Pharmacokinetic data from pediatric patients administered Cyclosporine Capsules USP MODIFIED or Sandimmune® (Cyclosporine Capsules USP) are very limited. In 15 renal transplant patients aged 3 to 16 years, cyclosporine whole blood clearance after IV administration of Sandimmune® (Cyclosporine Capsules USP) was 10.6±3.7 mL/min/kg (assay: Cyclo-trac specific RIA). In a study of 7 renal transplant patients aged 2 to 16, the cyclosporine clearance ranged from 9.8 to 15.5 mL/min/kg. In 9 liver transplant patients aged 0.6 to 5.6 years, clearance was 9.3±5.4 mL/min/kg (assay: HPLC).
In the pediatric population, Cyclosporine Capsules USP MODIFIED also demonstrates an increased bioavailability as compared to Sandimmune® (Cyclosporine Capsules USP). In 7 liver de novo transplant patients aged 1.4 to 10 years, the absolute bioavailability of Cyclosporine Capsules USP MODIFIED was 43% (range 30% to 68%) and for Sandimmune® (Cyclosporine Capsules USP) in the same individuals absolute bioavailability was 28% (range 17% to 42%).

Comparison of single dose data from both normal elderly volunteers (N=18, mean age 69 years) and elderly rheumatoid arthritis patients (N=16, mean age 68 years) to single dose data in young adult volunteers (N=16, mean age 26 years) showed no significant difference in the pharmacokinetic parameters.
The effectiveness of Sandimmune® (Cyclosporine Capsules USP) and Cyclosporine Capsules USP MODIFIED in the treatment of severe rheumatoid arthritis was evaluated in 5 clinical studies involving a total of 728 cyclosporine treated patients and 273 placebo treated patients.
A summary of the results is presented for the “responder” rates per treatment group, with a responder being defined as a patient having completed the trial with a 20% improvement in the tender and the swollen joint count and a 20% improvement in 2 of 4 of investigator global, patient global, disability, and erythrocyte sedimentation rates (ESR) for the Studies 651 and 652 and 3 of 5 of investigator global, patient global, disability, visual analog pain, and ESR for Studies 2008, 654 and 302.
Study 651 enrolled 264 patients with active rheumatoid arthritis with at least 20 involved joints, who had failed at least one major RA drug, using a 3:3:2 randomization to one of the following three groups: (1) cyclosporine dosed at 2.5 to 5 mg/kg/day, (2) methotrexate at 7.5 to 15 mg/week, or (3) placebo. Treatment duration was 24 weeks. The mean cyclosporine dose at the last visit was 3.1 mg/kg/day. See graph below.
Study 652 enrolled 250 patients with active RA with >6 active painful or tender joints who had failed at least one major RA drug. Patients were randomized using a 3:3:2 randomization to 1 of 3 treatment arms: (1) 1.5 to 5 mg/kg/day of cyclosporine, (2) 2.5 to 5 mg/kg/day of cyclosporine, and (3) placebo. Treatment duration was 16 weeks. The mean cyclosporine dose for group 2 at the last visit was 2.92 mg/kg/day. See graph below.
Study 2008 enrolled 144 patients with active RA and >6 active joints who had unsuccessful treatment courses of aspirin and gold or Penicillamine. Patients were randomized to 1 of 2 treatment groups (1) cyclosporine 2.5 to 5 mg/kg/day with adjustments after the first month to achieve a target trough level and (2) placebo. Treatment duration was 24 weeks. The mean cyclosporine dose at the last visit was 3.63 mg/kg/day. See graph below.
Study 654 enrolled 148 patients who remained with active joint counts of 6 or more despite treatment with maximally tolerated methotrexate doses for at least three months. Patients continued to take their current dose of methotrexate and were randomized to receive, in addition, one of the following medications: (1) cyclosporine 2.5 mg/kg/day with dose increases of 0.5 mg/kg/day at weeks 2 and 4 if there was no evidence of toxicity and further increases of 0.5 mg/kg/day at weeks 8 and 16 if a <30% decrease in active joint count occurred without any significant toxicity; dose decreases could be made at any time for toxicity or (2) placebo. Treatment duration was 24 weeks. The mean cyclosporine dose at the last visit was 2.8 mg/kg/day (range: 1.3 to 4.1). See graph below.
Study 302 enrolled 299 patients with severe active RA, 99% of whom were unresponsive or intolerant to at least one prior major RA drug. Patients were randomized to 1 of 2 treatment groups (1) Cyclosporine USP MODIFIED and (2) cyclosporine, both of which were started at 2.5 mg/kg/day and increased after 4 weeks for inefficacy in increments of 0.5 mg/kg/day to a maximum of 5 mg/kg/day and decreased at any time for toxicity. Treatment duration was 24 weeks. The mean cyclosporine dose at the last visit was 2.91 mg/kg/day (range: 0.72 to 5.17) for Cyclosporine Capsules USP MODIFIED and 3.27 mg/kg/day (range: 0.73 to 5.68) for cyclosporine. See graph below.
INDICATIONS AND USAGE
Kidney, Liver, and Heart Transplantation
Cyclosporine Capsules USP MODIFIED are indicated for the prophylaxis of organ rejection in kidney, liver, and heart allogeneic transplants. Cyclosporine Capsules USP MODIFIED have been used in combination with azathioprine and corticosteroids.
Cyclosporine Capsules USP MODIFIED are indicated for the treatment of patients with severe active, rheumatoid arthritis where the disease has not adequately responded to methotrexate. Cyclosporine Capsules USP MODIFIED can be used in combination with methotrexate in rheumatoid arthritis patients who do not respond adequately to methotrexate alone.
Cyclosporine Capsules USP MODIFIED are indicated for the treatment of adult, nonimmunocompromised patients with severe (i.e., extensive and/or disabling), recalcitrant, plaque psoriasis who have failed to respond to at least one systemic therapy (e.g., PUVA, retinoids, or methotrexate) or in patients for whom other systemic therapies are contraindicated, or cannot be tolerated.
While rebound rarely occurs, most patients will experience relapse with Cyclosporine Capsules USP MODIFIED as with other therapies upon cessation of treatment.
Cyclosporine Capsules USP MODIFIED are contraindicated in patients with a hypersensitivity to cyclosporine or to any of the ingredients of the formulation.
Rheumatoid arthritis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive Cyclosporine Capsules USP MODIFIED.
Psoriasis patients who are treated with Cyclosporine Capsules USP MODIFIED should not receive concomitant PUVA or UVB therapy, methotrexate or other immunosuppressive agents, coal tar or radiation therapy. Psoriasis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive Cyclosporine Capsules USP MODIFIED.
(See also Boxed WARNING)
Cyclosporine, the active ingredient of Cyclosporine Capsules USP MODIFIED, can cause nephrotoxicity and hepatotoxicity. The risk increases with increasing doses of cyclosporine. Renal dysfunction including structural kidney damage is a potential consequence of Cyclosporine Capsules USP MODIFIED and therefore renal function must be monitored during therapy. Care should be taken in using cyclosporine with nephrotoxic drugs(see PRECAUTIONS).
Patients receiving Cyclosporine Capsules USP MODIFIED require frequent monitoring of serum creatinine (see DOSAGE AND ADMINISTRATION, Special Monitoring). Elderly patients should be monitored with particular care, since decreases in renal function also occur with age. If patients are not properly monitored and doses are not properly adjusted, cyclosporine therapy can be associated with the occurrence of structural kidney damage and persistent renal dysfunction.
An increase in serum creatinine and BUN may occur during Cyclosporine Capsules USP MODIFIED therapy and reflect a reduction in the glomerular filtration rate. Impaired renal function at any time requires close monitoring, and frequent dosage adjustment may be indicated. The frequency and severity of serum creatinine elevations increase with dose and duration of cyclosporine therapy. These elevations are likely to become more pronounced without dose reduction or discontinuation.
Because Cyclosporine Capsules USP MODIFIED are not bioequivalent to Sandimmune® (Cyclosporine Capsules USP), conversion from Cyclosporine Capsules USP MODIFIED to Sandimmune® (Cyclosporine Capsules USP) using a 1:1 ratio (mg/kg/day) may result in lower cyclosporine blood concentrations. Conversion from Cyclosporine Capsules USP MODIFIED to Sandimmune® (Cyclosporine Capsules USP) should be made with increased monitoring to avoid the potential of underdosing.
Kidney, Liver, and Heart Transplant
Cyclosporine, the active ingredient of Cyclosporine Capsules USP MODIFIED, can cause nephrotoxicity and hepatotoxicity when used in high doses. It is not unusual for serum creatinine and BUN levels to be elevated during cyclosporine therapy. These elevations in renal transplant patients do not necessarily indicate rejection, and each patient must be fully evaluated before dosage adjustment is initiated.
Based on the historical Sandimmune® (Cyclosporine Capsules USP) experience with oral solution, nephrotoxicity associated with cyclosporine had been noted in 25% of cases of renal transplantation, 38% of cases of cardiac transplantation, and 37% of cases of liver transplantation. Mild nephrotoxicity was generally noted 2 to 3 months after renal transplant and consisted of an arrest in the fall of the pre-operative elevations of BUN and creatinine at a range of 35 to 45 mg/dL and 2 to 2.5 mg/dL respectively. These elevations were often responsive to cyclosporine dosage reduction.
More overt nephrotoxicity was seen early after transplantation and was characterized by a rapidly rising BUN and creatinine. Since these events are similar to renal rejection episodes, care must be taken to differentiate between them. This form of nephrotoxicity is usually responsive to cyclosporine dosage reduction.
Although specific diagnostic criteria which reliably differentiate renal graft rejection from drug toxicity have not been found, a number of parameters have been significantly associated with one or the other. It should be noted however, that up to 20% of patients may have simultaneous nephrotoxicity and rejection.

A form of a cyclosporine-associated nephropathy is characterized by serial deterioration in renal function and morphologic changes in the kidneys. From 5% to 15% of transplant recipients who have received cyclosporine will fail to show a reduction in rising serum creatinine despite a decrease or discontinuation of cyclosporine therapy. Renal biopsies from these patients will demonstrate one or several of the following alterations: tubular vacuolization, tubular microcalcifications, peritubular capillary congestion, arteriolopathy, and a striped form of interstitial fibrosis with tubular atrophy. Though none of these morphologic changes is entirely specific, a diagnosis of cyclosporine-associated structural nephrotoxicity requires evidence of these findings.
When considering the development of cyclosporine-associated nephropathy, it is noteworthy that several authors have reported an association between the appearance of interstitial fibrosis and higher cumulative doses or persistently high circulating trough levels of cyclosporine. This is particularly true during the first 6 post-transplant months when the dosage tends to be highest and when, in kidney recipients, the organ appears to be most vulnerable to the toxic effects of cyclosporine. Among other contributing factors to the development of interstitial fibrosis in these patients are prolonged perfusion time, warm ischemia time, as well as episodes of acute toxicity, and acute and chronic rejection. The reversibility of interstitial fibrosis and its correlation to renal function have not yet been determined. Reversibility of arteriolopathy has been reported after stopping cyclosporine or lowering the dosage.
Impaired renal function at any time requires close monitoring, and frequent dosage adjustment may be indicated.
In the event of severe and unremitting rejection, when rescue therapy with pulse steroids and monoclonal antibodies fail to reverse the rejection episode, it may be preferable to switch to alternative immunosuppressive therapy rather than increase the Cyclosporine Capsules USP MODIFIED dose to excessive levels.
Occasionally patients have developed a syndrome of thrombocytopenia and microangiopathic hemolytic anemia which may result in graft failure. The vasculopathy can occur in the absence of rejection and is accompanied by avid platelet consumption within the graft as demonstrated by Indium 111 labeled platelet studies. Neither the pathogenesis nor the management of this syndrome is clear. Though resolution has occurred after reduction or discontinuation of cyclosporine and 1) administration of streptokinase and heparin or 2) plasmapheresis, this appears to depend upon early detection with Indium 111 labeled platelet scans (see ADVERSE REACTIONS).
Significant hyperkalemia (sometimes associated with hyperchloremic metabolic acidosis) and hyperuricemia have been seen occasionally in individual patients.
Hepatotoxicity associated with cyclosporine use had been noted in 4% of cases of renal transplantation, 7% of cases of cardiac transplantation, and 4% of cases of liver transplantation. This was usually noted during the first month of therapy when high doses of cyclosporine were used and consisted of elevations of hepatic enzymes and bilirubin. The chemistry elevations usually decreased with a reduction in dosage.
As in patients receiving other immunosuppressants, those patients receiving cyclosporine are at increased risk for development of lymphomas and other malignancies, particularly those of the skin. Patients taking cyclosporine should be warned to avoid excess ultraviolet light exposure. The increased risk appears related to the intensity and duration of immunosuppression rather than to the use of specific agents. Because of the danger of oversuppression of the immune system resulting in increased risk of infection or malignancy, a treatment regimen containing multiple immunosuppressants should be used with caution. Some malignancies may be fatal. Transplant patients receiving cyclosporine are at increased risk for serious infection with fatal outcome.
Latent Viral Infections
Immunosuppressed patients are at increased risk for opportunistic infections, including activation of latent viral infections. These include BK virus-associated nephropathy which has been observed in patients receiving immunosuppressants, including Cyclosporine Capsules USP MODIFIED. This infection is associated with serious outcomes, including deteriorating renal function and renal graft loss. Patient monitoring may help detect patients at risk for BK virus-associated nephropathy. Reduction in immunosuppression should be considered for patients who develop evidence of BK virus-associated nephropathy.
There have been reports of convulsions in adult and pediatric patients receiving cyclosporine, particularly in combination with high dose methylprednisolone.
Encephalopathy has been described both in post-marketing reports and in the literature. Manifestations include impaired consciousness, convulsions, visual disturbances (including blindness), loss of motor function, movement disorders and psychiatric disturbances. In many cases, changes in the white matter have been detected using imaging techniques and pathologic specimens. Predisposing factors such as hypertension, hypomagnesemia, hypocholesterolemia, high-dose corticosteroids, high cyclosporine blood concentrations, and graft-versus-host disease have been noted in many but not all of the reported cases. The changes in most cases have been reversible upon discontinuation of cyclosporine, and in some cases improvement was noted after reduction of dose. It appears that patients receiving liver transplant are more susceptible to encephalopathy than those receiving kidney transplant. Another rare manifestation of cyclosporine-induced neurotoxicity, occurring in transplant patients more frequently than in other indications, is optic disc edema including papilloedema, with possible visual impairment, secondary to benign intracranial hypertension.
Care should be taken in using cyclosporine with nephrotoxic drugs (see PRECAUTIONS).
Cyclosporine nephropathy was detected in renal biopsies of 6 out of 60 (10%) rheumatoid arthritis patients after the average treatment duration of 19 months. Only one patient, out of these 6 patients, was treated with a dose ≤4 mg/kg/day. Serum creatinine improved in all but one patient after discontinuation of cyclosporine. The “maximal creatinine increase” appears to be a factor in predicting cyclosporine nephropathy.
There is a potential, as with other immunosuppressive agents, for an increase in the occurrence of malignant lymphomas with cyclosporine. It is not clear whether the risk with cyclosporine is greater than that in rheumatoid arthritis patients or in rheumatoid arthritis patients on cytotoxic treatment for this indication. Five cases of lymphoma were detected: four in a survey of approximately 2,300 patients treated with cyclosporine for rheumatoid arthritis, and another case of lymphoma was reported in a clinical trial. Although other tumors (12 skin cancers, 24 solid tumors of diverse types, and 1 multiple myeloma) were also reported in this survey, epidemiologic analyses did not support a relationship to cyclosporine other than for malignant lymphomas.
Patients should be thoroughly evaluated before and during Cyclosporine Capsules USP MODIFIED treatment for the development of malignancies. Moreover, use of Cyclosporine Capsules USP MODIFIED therapy with other immunosuppressive agents may induce an excessive immunosuppression which is known to increase the risk of malignancy.
(See also Boxed WARNINGS for Psoriasis)
Since cyclosporine is a potent immunosuppressive agent with a number of potentially serious side effects, the risks and benefits of using Cyclosporine Capsules USP MODIFIED should be considered before treatment of patients with psoriasis. Cyclosporine, the active ingredient in Cyclosporine Capsules USP MODIFIED, can cause nephrotoxicity and hypertension (see PRECAUTIONS) and the risk increases with increasing dose and duration of therapy. Patients who may be at increased risk such as those with abnormal renal function, uncontrolled hypertension or malignancies, should not receive Cyclosporine Capsules USP MODIFIED.
Renal dysfunction is a potential consequence of Cyclosporine Capsules USP MODIFIED therefore renal function must be monitored during therapy.
Patients receiving Cyclosporine Capsules USP MODIFIED require frequent monitoring of serum creatinine (see DOSAGE AND ADMINISTRATION, Special Monitoring). Elderly patients should be monitored with particular care, since decreases in renal function also occur with age. If patients are not properly monitored and doses are not properly adjusted, cyclosporine therapy can cause structural kidney damage and persistent renal dysfunction.
An increase in serum creatinine and BUN may occur during Cyclosporine Capsules USP MODIFIED therapy and reflects a reduction in the glomerular filtration rate.
Kidney biopsies from 86 psoriasis patients treated for a mean duration of 23 months with 1.2 to 7.6 mg/kg/day of cyclosporine showed evidence of cyclosporine nephropathy in 18/86 (21%) of the patients. The pathology consisted of renal tubular atrophy and interstitial fibrosis. On repeat biopsy of 13 of these patients maintained on various dosages of cyclosporine for a mean of 2 additional years, the number with cyclosporine induced nephropathy rose to 26/86 (30%). The majority of patients (19/26) were on a dose of ≥5 mg/kg/day (the highest recommended dose is 4 mg/kg/day). The patients were also on cyclosporine for greater than 15 months (18/26) and/or had a clinically significant increase in serum creatinine for greater than 1 month (21/26). Creatinine levels returned to normal range in 7 of 11 patients in whom cyclosporine therapy was discontinued.
There is an increased risk for the development of skin and lymphoproliferative malignancies in cyclosporine-treated psoriasis patients. The relative risk of malignancies is comparable to that observed in psoriasis patients treated with other immunosuppressive agents.
Tumors were reported in 32 (2.2%) of 1439 psoriasis patients treated with cyclosporine worldwide from clinical trials. Additional tumors have been reported in 7 patients in cyclosporine postmarketing experience. Skin malignancies were reported in 16 (1.1%) of these patients; all but 2 of them had previously received PUVA therapy. Methotrexate was received by 7 patients. UVB and coal tar had been used by 2 and 3 patients, respectively. Seven patients had either a history of previous skin cancer or a potentially predisposing lesion was present prior to cyclosporine exposure. Of the 16 patients with skin cancer, 11 patients had 18 squamous cell carcinomas and 7 patients had 10 basal cell carcinomas.
There were two lymphoproliferative malignancies; one case of non-Hodgkin’s lymphoma which required chemotherapy, and one case of mycosis fungoides which regressed spontaneously upon discontinuation of cyclosporine. There were four cases of benign lymphocytic infiltration: 3 regressed spontaneously upon discontinuation of cyclosporine, while the fourth regressed despite continuation of the drug. The remainder of the malignancies, 13 cases (0.9%), involved various organs.
Patients should not be treated concurrently with cyclosporine and PUVA or UVB, other radiation therapy, or other immunosuppressive agents, because of the possibility of excessive immunosuppression and the subsequent risk of malignancies (see CONTRAINDICATIONS). Patients should also be warned to protect themselves appropriately when in the sun, and to avoid excessive sun exposure. Patients should be thoroughly evaluated before and during treatment for the presence of malignancies remembering that malignant lesions may be hidden by psoriatic plaques. Skin lesions not typical of psoriasis should be biopsied before starting treatment. Patients should be treated with Cyclosporine Capsules USP MODIFIED only after complete resolution of suspicious lesions, and only if there are no other treatment options (see Special Monitoring for Psoriasis Patients).
Cyclosporine is the active ingredient of Cyclosporine Capsules USP MODIFIED. Hypertension is a common side effect of cyclosporine therapy which may persist (see ADVERSE REACTIONS and DOSAGE AND ADMINISTRATION for monitoring recommendations). Mild or moderate hypertension is encountered more frequently than severe hypertension and the incidence decreases over time. In recipients of kidney, liver, and heart allografts treated with cyclosporine, antihypertensive therapy may be required (see Special Monitoring of Rheumatoid Arthritis Patientsand Psoriasis Patients). However, since cyclosporine may cause hyperkalemia, potassium-sparing diuretics should not be used. While calcium antagonists can be effective agents in treating cyclosporine-associated hypertension, they can interfere with cyclosporine metabolism (see Drug Interactions).
During treatment with cyclosporine, vaccination may be less effective; and the use of live attenuated vaccines should be avoided.
Special Monitoring of Rheumatoid Arthritis Patients
Before initiating treatment, a careful physical examination, including blood pressure measurements (on at least two occasions) and two creatinine levels to estimate baseline should be performed. Blood pressure and serum creatinine should be evaluated every 2 weeks during the initial 3 months and then monthly if the patient is stable. It is advisable to monitor serum creatinine and blood pressure always after an increase of the dose of nonsteroidal anti-inflammatory drugs and after initiation of new nonsteroidal anti-inflammatory drug therapy during Cyclosporine Capsules USP MODIFIED treatment. If coadministered with methotrexate, CBC and liver function tests are recommended to be monitored monthly (see also PRECAUTIONS, General, Hypertension).
In patients who are receiving cyclosporine, the dose of Cyclosporine Capsules USP MODIFIED should be decreased by 25% to 50% if hypertension occurs. If hypertension persists, the dose of Cyclosporine Capsules USP MODIFIED should be further reduced or blood pressure should be controlled with antihypertensive agents. In most cases, blood pressure has returned to baseline when cyclosporine was discontinued.
In placebo-controlled trials of rheumatoid arthritis patients, systolic hypertension (defined as an occurrence of two systolic blood pressure readings >140 mmHg) and diastolic hypertension (defined as two diastolic blood pressure readings >90 mmHg) occurred in 33% and 19% of patients treated with cyclosporine, respectively. The corresponding placebo rates were 22% and 8%.
Special Monitoring for Psoriasis Patients
Before initiating treatment, a careful dermatological and physical examination, including blood pressure measurements (on at least two occasions) should be performed. Since Cyclosporine Capsules USP MODIFIED is an immunosuppressive agent, patients should be evaluated for the presence of occult infection on their first physical examination and for the presence of tumors initially, and throughout treatment with Cyclosporine Capsules USP MODIFIED. Skin lesions not typical for psoriasis should be biopsied before starting Cyclosporine Capsules USP MODIFIED. Patients with malignant or premalignant changes of the skin should be treated with Cyclosporine Capsules USP MODIFIED only after appropriate treatment of such lesions and if no other treatment option exists.
Baseline laboratories should include serum creatinine (on two occasions), BUN, CBC, serum magnesium, potassium, uric acid, and lipids.
The risk of cyclosporine nephropathy is reduced when the starting dose is low (2.5 mg/kg/day), the maximum dose does not exceed 4 mg/kg/day, serum creatinine is monitored regularly while cyclosporine is administered, and the dose of Cyclosporine Capsules USP MODIFIED is decreased when the rise in creatinine is greater than or equal to 25% above the patients pretreatment level. The increase in creatinine is generally reversible upon timely decrease of the dose of Cyclosporine Capsules USP MODIFIED or its discontinuation.
Serum creatinine and BUN should be evaluated every 2 weeks during the initial 3 months of therapy and then monthly if the patient is stable. If the serum creatinine is greater than or equal to 25% above the patient’s pretreatment level, serum creatinine should be repeated within two weeks. If the change in serum creatinine remains greater than or equal to 25% above baseline, Cyclosporine Capsules USP MODIFIED should be reduced by 25% to 50%. If at any time the serum creatinine increases by greater than or equal to 50% above pretreatment level, Cyclosporine Capsules USP MODIFIED should be reduced by 25% to 50%. Cyclosporine Capsules USP MODIFIED should be discontinued if reversibility (within 25% of baseline) of serum creatinine is not achievable after two dosage modifications. It is advisable to monitor serum creatinine after an increase of the dose of nonsteroidal anti-inflammatory drug and after initiation of new nonsteroidal anti-inflammatory therapy during Cyclosporine Capsules USP MODIFIED treatment.
Blood pressure should be evaluated every 2 weeks during the initial 3 months of therapy and then monthly if the patient is stable, or more frequently when dosage adjustments are made. Patients without a history of previous hypertension before initiation of treatment with Cyclosporine Capsules USP MODIFIED, should have the drug reduced by 25% to 50% if found to have sustained hypertension. If the patient continues to be hypertensive despite multiple reductions of Cyclosporine Capsules USP MODIFIED, then Cyclosporine Capsules USP MODIFIED should be discontinued. For patients with treated hypertension, before the initiation of Cyclosporine Capsules USP MODIFIED therapy, their medication should be adjusted to control hypertension while on Cyclosporine Capsules USP MODIFIED. Cyclosporine Capsules USP MODIFIED should be discontinued if a change in hypertension management is not effective or tolerable.
CBC, uric acid, potassium, lipids, and magnesium should also be monitored every 2 weeks for the first 3 months of therapy, and then monthly if the patient is stable or more frequently when dosage adjustments are made. Cyclosporine Capsules USP MODIFIED dosage should be reduced by 25% to 50% for any abnormality of clinical concern.
In controlled trials of cyclosporine in psoriasis patients, cyclosporine blood concentrations did not correlate well with either improvement or with side effects such as renal dysfunction.
Information for Patients
Patients should be advised that any change of cyclosporine formulation should be made cautiously and only under physician supervision because it may result in the need for a change in dosage.
Patients should be informed of the necessity of repeated laboratory tests while they are receiving cyclosporine. Patients should be advised of the potential risks during pregnancy and informed of the increased risk of neoplasia. Patients should also be informed of the risk of hypertension and renal dysfunction.
Patients should be advised that during treatment with cyclosporine, vaccination may be less effective and the use of live attenuated vaccines should be avoided.
Patients should be given careful dosage instructions.
Patients should be advised to take Cyclosporine Capsules USP MODIFIED on a consistent schedule with regard to time of day and relation to meals. Grapefruit and grapefruit juice affect metabolism, increasing blood concentration of cyclosporine, thus should be avoided.
In all patients treated with cyclosporine, renal and liver functions should be assessed repeatedly by measurement of serum creatinine, BUN, serum bilirubin, and liver enzymes. Serum lipids, magnesium, and potassium should also be monitored. Cyclosporine blood concentrations should be routinely monitored in transplant patients (see DOSAGE AND ADMINISTRATION, Blood Concentration Monitoring in Transplant Patients), and periodically monitored in rheumatoid arthritis patients.
All of the individual drugs cited below are well substantiated to interact with cyclosporine. In addition, concomitant non-steroidal anti-inflammatory drugs, particularly in the setting of dehydration, may potentiate renal dysfunction.
Drugs That May Potentiate Renal Dysfunction Antibiotics Antineoplastics Anti-inflammatory Drugs Gastrointestinal Agents
trimethoprim with sulfamethoxazole
fibric acid derivatives (e.g., bezafibrate, fenofibrate)methotrexate
Drugs That Alter Cyclosporine Concentrations
Cyclosporine is extensively metabolized by CYP 3A isoenzymes, in particular CYP3A4, and is a substrate of the multidrug efflux transporter P-glycoprotein. Various agents are known to either increase or decrease plasma or whole blood of cyclosporine levels usually by inhibition or induction of CYP3A4 or P-glycoprotein transporter or both. Compounds that decrease cyclosporine absorption such as orlistat should be avoided. Monitoring of circulating cyclosporine concentrations and appropriate Cyclosporine Capsules USP MODIFIED dosage adjustment are essential when these drugs are used concomitantly (see Blood Concentration Monitoring).
Drugs That Increase Cyclosporine Concentrations Calcium Channel Blockers Antifungals Antibiotics Glucocorticoids Other Drugs
The HIV protease inhibitors (e.g., indinavir, nelfinavir, ritonavir, and saquinavir) are known to inhibit cytochrome P-450 3A and thus could potentially increase the concentrations of cyclosporine, however no formal studies of the interaction are available. Care should be exercised when these drugs are administered concomitantly.
Grapefruit and grapefruit juice affect metabolism, increasing blood concentrations of cyclosporine, thus should be avoided.
Drugs/Dietary Supplements That Decrease Cyclosporine Concentrations
Other Drugs / Dietary Supplements
St. John’s Wort
There have been reports of a serious drug interaction between cyclosporine and the herbal dietary supplement, St. John’sWort. This interaction has been reported to produce a marked reduction in the blood concentrations of cyclosporine, resulting in sub-therapeutic levels, rejection of transplanted organs, and graft loss.
Rifabutin is known to increase the metabolism of other drugs metabolized by the cytochrome P-450 system. The interaction between rifabutin and cyclosporine has not been studied. Care should be exercised when these two drugs are administered concomitantly.
Nonsteroidal Anti-inflammatory Drug (NSAID) Interactions
Clinical status and serum creatinine should be closely monitored when cyclosporine is used with nonsteroidal anti-inflammatory agents in rheumatoid arthritis patients (see WARNINGS).
Pharmacodynamic interactions have been reported to occur between cyclosporine and both naproxen and sulindac, in that concomitant use is associated with additive decreases in renal function, as determined by 99mTc-diethylenetriaminepentaacetic acid (DTPA) and (p-aminohippuric acid) PAH clearances. Although concomitant administration of diclofenac does not affect blood levels of cyclosporine, it has been associated with approximate doubling of diclofenac blood levels and occasional reports of reversible decreases in renal function. Consequently, the dose of diclofenac should be in the lower end of the therapeutic range.
Preliminary data indicate that when methotrexate and cyclosporine were coadministered to rheumatoid arthritis patients (N=20), methotrexate concentrations (AUCs) were increased approximately 30% and the concentrations (AUCs) of its metabolite, 7-hydroxy methotrexate, were decreased by approximately 80%. The clinical significance of this interaction is not known. Cyclosporine concentrations do not appear to have been altered (N=6).
Other Drug Interactions
Cyclosporine is an inhibitor of CYP3A4 and of the multidrug efflux transporter P-glycoprotein and may increase plasma concentrations of comedications that are substrates of CYP3A4 or P-glycoprotein or both.
Cyclosporine may reduce the clearance of digoxin, colchicine, prednisolone, HMG-CoA reductase inhibitors (statins) and etoposide. Severe digitalis toxicity has been seen within days of starting cyclosporine in several patients taking digoxin. There are also reports on the potential of cyclosporine to enhance the toxic effects of colchicine such as myopathy and neuropathy, especially in patients with renal dysfunction. If digoxin or colchicine are used concurrently with cyclosporine, close clinical observation is required in order to enable early detection of toxic manifestations of digoxin or colchicine, followed by reduction of dosage or its withdrawal.
Literature and postmarketing cases of myotoxicity, including muscle pain and weakness, myositis, and rhabdomyolysis, have been reported with concomitant administration of cyclosporine with lovastatin, simvastatin, atorvastatin, pravastatin, and rarely, fluvastatin. When concurrently administered with cyclosporine, the dosage of these statins should be reduced according to label recommendations. Statin therapy needs to be temporarily withheld or discontinued in patients with signs and symptoms of myopathy or those with risk factors predisposing to severe renal injury, including renal failure, secondary to rhabdomyolysis.
Cyclosporine may increase the plasma concentrations of repaglinide and thereby increase the risk of hypoglycemia. In 12 healthy male subjects who received two doses of 100 mg cyclosporine capsule orally 12 hours apart with a single dose of 0.25 mg repaglinide tablet (one half of a 0.5 mg tablet) orally 13 hours after the cyclosporine initial dose, the repaglinide mean Cmax and AUC were increased 1.8 fold (range: 0.6 to 3.7 fold) and 2.4 fold (range 1.2 to 5.3 fold), respectively. Close monitoring of blood glucose level is advisable for a patient taking cyclosporine and repaglinide concomitantly.
Cyclosporine should not be used with potassium-sparing diuretics because hyperkalemia can occur. Caution is also required when cyclosporine is coadministered with potassium sparing drugs (e.g., angiotensin converting enzyme inhibitors, angiotensin II receptor antagonists), potassium containing drugs as well as patients on a potassium rich diet. Control of potassium levels in these situations is advisable.
Elevations in serum creatinine were observed in studies using sirolimus in combination with full-dose cyclosporine. This effect is often reversible with cyclosporine dose reduction. Simultaneous coadministration of cyclosporine significantly increases blood levels of sirolimus. To minimize increases in sirolimus concentrations, it is recommended that sirolimus be given 4 hours after cyclosporine administration.
During treatment with cyclosporine, vaccination may be less effective. The use of live vaccines should be avoided. Frequent gingival hyperplasia with nifedipine, and convulsions with high dose methylprednisolone have been reported.
Psoriasis patients receiving other immunosuppressive agents or radiation therapy (including PUVA and UVB) should not receive concurrent cyclosporine because of the possibility of excessive immunosuppression.

Carcinogenesis, Mutagenesis, and Impairment of Fertility
Carcinogenicity studies were carried out in male and female rats and mice. In the 78-week mouse study, evidence of a statistically significant trend was found for lymphocytic lymphomas in females, and the incidence of hepatocellular carcinomas in mid-dose males significantly exceeded the control value. In the 24-month rat study, pancreatic islet cell adenomas significantly exceeded the control rate in the low dose level. Doses used in the mouse and rat studies were 0.01 to 0.16 times the clinical maintenance dose (6 mg/kg). The hepatocellular carcinomas and pancreatic islet cell adenomas were not dose related. Published reports indicate that co-treatment of hairless mice with UV irradiation and cyclosporine or other immunosuppressive agents shorten the time to skin tumor formation compared to UV irradiation alone.
Cyclosporine was not mutagenic in appropriate test systems. Cyclosporine has not been found to be mutagenic/genotoxic in the Ames Test, the V79-HGPRT Test, the micronucleus test in mice and Chinese hamsters, the chromosome-aberration tests in Chinese hamster bone-marrow, the mouse dominant lethal assay, and the DNA-repair test in sperm from treated mice. A recent study analyzing sister chromatid exchange (SCE) induction by cyclosporine using human lymphocytes in vitro gave indication of a positive effect (i.e., induction of SCE), at high concentrations in this system. In two published research studies, rabbits exposed to cyclosporine in utero (10 mg/kg/day subcutaneously) demonstrated reduced numbers of nephrons, renal hypertrophy, systemic hypertension and progressive renal insufficiency up to 35 weeks of age. Pregnant rats which received 12 mg/kg/day of cyclosporine intravenously (twice the recommended human intravenous dose) had fetuses with an increased incidence of ventricular septal defect. These findings have not been demonstrated in other species and their relevance for humans is unknown.
No impairment in fertility was demonstrated in studies in male and female rats.
Widely distributed papillomatosis of the skin was observed after chronic treatment of dogs with cyclosporine at 9 times the human initial psoriasis treatment dose of 2.5 mg/kg, where doses are expressed on a body surface area basis. This papillomatosis showed a spontaneous regression upon discontinuation of cyclosporine.
An increased incidence of malignancy is a recognized complication of immunosuppression in recipients of organ transplants and patients with rheumatoid arthritis and psoriasis. The most common forms of neoplasms are non-Hodgkin’s lymphoma and carcinomas of the skin. The risk of malignancies in cyclosporine recipients is higher than in the normal, healthy population but similar to that in patients receiving other immunosuppressive therapies. Reduction or discontinuance of immunosuppression may cause the lesions to regress.
In psoriasis patients on cyclosporine, development of malignancies, especially those of the skin has been reported (see WARNINGS). Skin lesions not typical for psoriasis should be biopsied before starting cyclosporine treatment. Patients with malignant or premalignant changes of the skin should be treated with cyclosporine only after appropriate treatment of such lesions and if no other treatment option exists.
Pregnancy Category C
Animal studies have shown reproductive toxicity in rats and rabbits. Cyclosporine gave no evidence of mutagenic or teratogenic effects in the standard test systems with oral application (rats up to 17 mg/kg and rabbits up to 30 mg/kg per day orally). Only at dose levels toxic to dams, were adverse effects seen in reproduction studies in rats. Cyclosporine has been shown to be embryo- and fetotoxic in rats and rabbits following oral administration at maternally toxic doses. Fetal toxicity was noted in rats at 0.8 and rabbits at 5.4 times the transplant doses in humans of 6 mg/kg, where dose corrections are based on body surface area. Cyclosporine was embryo- and fetotoxic as indicated by increased pre- and postnatal mortality and reduced fetal weight together with related skeletal retardation.
There are no adequate and well-controlled studies in pregnant women, therefore, Cyclosporine Capsules USP MODIFIED should not be used during pregnancy unless the potential benefit to the mother justifies the potential risk to the fetus.
In pregnant transplant recipients who are being treated with immunosuppressants the risk of premature births is increased. The following data represent the reported outcomes of 116 pregnancies in women receiving cyclosporine during pregnancy, 90% of whom were transplant patients, and most of whom received cyclosporine throughout the entire gestational period. The only consistent patterns of abnormality were premature birth (gestational period of 28 to 36 weeks) and low birth weight for gestational age. Sixteen fetal losses occurred. Most of the pregnancies (85 of 100) were complicated by disorders; including pre-eclampsia, eclampsia, premature labor, abruptio placentae, oligohydramnios, Rh incompatibility, and fetoplacental dysfunction. Pre-term delivery occurred in 47%. Seven malformations were reported in 5 viable infants and in 2 cases of fetal loss. Twenty-eight percent of the infants were small for gestational age. Neonatal complications occurred in 27%. Therefore, the risks and benefits of using Cyclosporine Capsules USP MODIFIED during pregnancy should be carefully weighed.
A limited number of observations in children exposed to cyclosporine in utero are available, up to an age of approximately 7 years. Renal function and blood pressure in these children were normal. Because of the possible disruption of maternal-fetal interaction, the risk/benefit ratio of using Cyclosporine Capsules USP MODIFIED in psoriasis patients during pregnancy should carefully be weighed with serious consideration for discontinuation of Cyclosporine Capsules USP MODIFIED.
Cyclosporine passes into breast milk. Mothers receiving treatment with Cyclosporine Capsules USP MODIFIED should not breast-feed.
Although no adequate and well-controlled studies have been completed in pediatric patients, transplant recipients as young as one year of age have received Cyclosporine Capsules USP MODIFIED with no unusual adverse effects. The safety and efficacy of Cyclosporine Capsules USP MODIFIED treatment in pediatric patients with juvenile rheumatoid arthritis or psoriasis below the age of 18 have not been established.
In rheumatoid arthritis clinical trials with cyclosporine, 17.5% of patients were age 65 or older. These patients were more likely to develop systolic hypertension on therapy, and more likely to show serum creatinine rises ≥50% above the baseline after 3 to 4 months of therapy.
Clinical studies of Cyclosporine Capsules USP MODIFIED in transplant and psoriasis patients did not include a sufficient number of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experiences have not identified differences in response between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Kidney, Liver, and Heart Transplantation
The principal adverse reactions of cyclosporine therapy are renal dysfunction, tremor, hirsutism, hypertension, and gum hyperplasia.
Hypertension, which is usually mild to moderate, may occur in approximately 50% of patients following renal transplantation and in most cardiac transplant patients.
Glomerular capillary thrombosis has been found in patients treated with cyclosporine and may progress to graft failure. The pathologic changes resembled those seen in the hemolytic-uremic syndrome and included thrombosis of the renal microvasculature, with platelet-fibrin thrombi occluding glomerular capillaries and afferent arterioles, microangiopathic hemolytic anemia, thrombocytopenia, and decreased renal function. Similar findings have been observed when other immunosuppressives have been employed post-transplantation.
Hypomagnesemia has been reported in some, but not all, patients exhibiting convulsions while on cyclosporine therapy. Although magnesium-depletion studies in normal subjects suggest that hypomagnesemia is associated with neurologic disorders, multiple factors, including hypertension, high dose methylprednisolone, hypocholesterolemia, and nephrotoxicity associated with high plasma concentrations of cyclosporine appear to be related to the neurological manifestations of cyclosporine toxicity.
In controlled studies, the nature, severity and incidence of the adverse events that were observed in 493 transplanted patients treated with Cyclosporine Capsules USP MODIFIED were comparable with those observed in 208 transplanted patients who received Sandimmune® (Cyclosporine Capsules USP) in these same studies when the dosage of the two drugs was adjusted to achieve the same cyclosporine blood trough concentrations.
Based on the historical experience with Sandimmune® (Cyclosporine Capsules USP), the following reactions occurred in 3% or greater of 892 patients involved in clinical trials of kidney, heart, and liver transplants.

Among 705 kidney transplant patients treated with Sandimmune® (Cyclosporine Oral Solution USP) in clinical trials, the reason for treatment discontinuation was renal toxicity in 5.4%, infection in 0.9%, lack of efficacy in 1.4%, acute tubular necrosis in 1%, lymphoproliferative disorders in 0.3%, hypertension in 0.3%, and other reasons in 0.7% of the patients.
The following reactions occurred in 2% or less of Sandimmune® (Cyclosporine Capsules USP) treated patients: allergic reactions, anemia, anorexia, confusion, conjunctivitis, edema, fever, brittle fingernails, gastritis, hearing loss, hiccups, hyperglycemia, muscle pain, peptic ulcer, thrombocytopenia, tinnitus.
The following reactions occurred rarely: anxiety, chest pain, constipation, depression, hair breaking, hematuria, joint pain, lethargy, mouth sores, myocardial infarction, night sweats, pancreatitis, pruritus, swallowing difficulty, tingling, upper GI bleeding, visual disturbance, weakness, weight loss.
Patients receiving immunosuppressive therapies, including cyclosporine and cyclosporine-containing regimens, are at increased risk of infections (viral, bacterial, fungal, parasitic). Both generalized and localized infections can occur. Preexisting infections may also be aggravated. Fatal outcomes have been reported (see WARNINGS).

Postmarketing Experience, Kidney, Liver and Heart Transplantation
BK virus associated nephropathy has been observed in patients receiving immunosuppressants, including Cyclosporine Capsules USP MODIFIED. This infection is associated with serious outcomes, including deteriorating renal function and renal graft loss (see WARNINGS, Kidney, Liver and Heart Transplant).
The principal adverse reactions associated with the use of cyclosporine in rheumatoid arthritis are renal dysfunction (see WARNINGS), hypertension (see PRECAUTIONS), headache, gastrointestinal disturbances, and hirsutism/hypertrichosis.
In rheumatoid arthritis patients treated in clinical trials within the recommended dose range, cyclosporine therapy was discontinued in 5.3% of the patients because of hypertension and in 7% of the patients because of increased creatinine. These changes are usually reversible with timely dose decrease or drug discontinuation. The frequency and severity of serum creatinine elevations increase with dose and duration of cyclosporine therapy. These elevations are likely to become more pronounced without dose reduction or discontinuation.
The following adverse events occurred in controlled clinical trials:

The principal adverse reactions associated with the use of cyclosporine in patients with psoriasis are renal dysfunction, headache, hypertension, hypertriglyceridemia, hirsutism/hypertrichosis, paresthesia or hyperesthesia, influenza-like symptoms, nausea/vomiting, diarrhea, abdominal discomfort, lethargy, and musculoskeletal or joint pain.
In psoriasis patients treated in US controlled clinical studies within the recommended dose range, cyclosporine therapy was discontinued in 1% of the patients because of hypertension and in 5.4% of the patients because of increased creatinine. In the majority of cases, these changes were reversible after dose reduction or discontinuation of cyclosporine.
There has been one reported death associated with the use of cyclosporine in psoriasis. A 27 year-old male developed renal deterioration and was continued on cyclosporine. He had progressive renal failure leading to death.
Frequency and severity of serum creatinine increases with dose and duration of cyclosporine therapy. These elevations are likely to become more pronounced and may result in irreversible renal damage without dose reduction or discontinuation.

Mild hypomagnesemia and hyperkalemia may occur but are asymptomatic. Increases in uric acid may occur and attacks of gout have been rarely reported. A minor and dose related hyperbilirubinemia has been observed in the absence of hepatocellular damage. Cyclosporine therapy may be associated with a modest increase of serum triglycerides or cholesterol. Elevations of triglycerides (>750 mg/dL) occur in about 15% of psoriasis patients; elevations of cholesterol (>300 mg/dL) are observed in less than 3% of psoriasis patients. Generally these laboratory abnormalities are reversible upon dose reduction or discontinuation of cyclosporine.
There is a minimal experience with cyclosporine overdosage. Forced emesis and gastric lavage can be of value up to 2 hours after administration of Cyclosporine Capsules USP MODIFIED. Transient hepatotoxicity and nephrotoxicity may occur which should resolve following drug withdrawal. Oral doses of cyclosporine up to 10 g (about 150 mg/kg) have been tolerated with relatively minor clinical consequences, such as vomiting, drowsiness, headache, tachycardia and, in a few patients, moderately severe, reversible impairment of renal function. However, serious symptoms of intoxication have been reported following accidental parenteral overdosage with cyclosporine in premature neonates. General supportive measures and symptomatic treatment should be followed in all cases of overdosage. Cyclosporine is not dialyzable to any great extent, nor is it cleared well by charcoal hemoperfusion. The oral dosage at which half of experimental animals are estimated to die is 31 times, 39 times and >54 times the human maintenance dose for transplant patients (6 mg/kg; corrections based on body surface area) in mice, rats, and rabbits.
DOSAGE AND ADMINISTRATION
Cyclosporine Capsules USP MODIFIED, soft gelatin capsules, has increased bioavailability in comparison to Sandimmune® (Cyclosporine Capsules USP). Cyclosporine Capsules USP MODIFIED and Sandimmune® (Cyclosporine Capsules USP) are not bioequivalent and cannot be used interchangeably without physician supervision.
The daily dose of Cyclosporine Capsules USP MODIFIED should always be given in two divided doses (BID). It is recommended that Cyclosporine Capsules USP MODIFIED be administered on a consistent schedule with regard to time of day and relation to meals. Grapefruit and grapefruit juice affect metabolism, increasing blood concentration of cyclosporine, thus should be avoided.
Newly Transplanted Patients
The initial oral dose of Cyclosporine Capsules USP MODIFIED can be given 4 to 12 hours prior to transplantation or be given postoperatively. The initial dose of Cyclosporine Capsules USP MODIFIED varies depending on the transplanted organ and the other immunosuppressive agents included in the immunosuppressive protocol. In newly transplanted patients, the initial oral dose of Cyclosporine Capsules USP MODIFIED is the same as the initial oral dose of Sandimmune® (Cyclosporine Capsules USP). Suggested initial doses are available from the results of a 1994 survey of the use of Sandimmune® (Cyclosporine Capsules USP) in US transplant centers. The mean ±SD initial doses were 9±3 mg/kg/day for renal transplant patients (75 centers), 8±4 mg/kg/day for liver transplant patients (30 centers), and 7±3 mg/kg/day for heart transplant patients (24 centers). Total daily doses were divided into two equal daily doses. The Cyclosporine Capsules USP MODIFIED dose is subsequently adjusted to achieve a pre-defined cyclosporine blood concentration (see Blood Concentration Monitoring in Transplant Patients, below). If cyclosporine trough blood concentrations are used, the target range is the same for Cyclosporine Capsules USP MODIFIED as for Sandimmune® (Cyclosporine Capsules USP). Using the same trough concentration target range for Cyclosporine Capsules USP MODIFIED as for Sandimmune® (Cyclosporine Capsules USP) results in greater cyclosporine exposure when Cyclosporine Capsules USP MODIFIED is administered (see Pharmacokinetics, Absorption). Dosing should be titrated based on clinical assessments of rejection and tolerability. Lower Cyclosporine Capsules USP MODIFIED doses may be sufficient as maintenance therapy.
Adjunct therapy with adrenal corticosteroids is recommended initially. Different tapering dosage schedules of prednisone appear to achieve similar results. A representative dosage schedule based on the patient’s weight started with 2 mg/kg/day for the first 4 days tapered to 1 mg/kg/day by 1 week, 0.6 mg/kg/day by 2 weeks, 0.3 mg/kg/day by 1 month, and 0.15 mg/kg/day by 2 months and thereafter as a maintenance dose. Steroid doses may be further tapered on an individualized basis depending on status of patient and function of graft. Adjustments in dosage of prednisone must be made according to the clinical situation.
Conversion from Sandimmune® (Cyclosporine Capsules USP) to Cyclosporine Capsules USP MODIFIED in Transplant Patients
In transplanted patients who are considered for conversion to Cyclosporine Capsules USP MODIFIED from Sandimmune® (Cyclosporine Capsules USP), Cyclosporine Capsules USP MODIFIED should be started with the same daily dose as was previously used with Sandimmune® (Cyclosporine Capsules USP) (1:1 dose conversion). The Cyclosporine Capsules USP MODIFIED dose should subsequently be adjusted to attain the pre-conversion cyclosporine blood trough concentration. Using the same trough concentration target range for Cyclosporine Capsules USP MODIFIED as for Sandimmune® (Cyclosporine Capsules USP) results in greater cyclosporine exposure when Cyclosporine Capsules USP MODIFIED is administered (see Pharmacokinetics, Absorption). Patients with suspected poor absorption of Sandimmune® (Cyclosporine Capsules USP) require different dosing strategies (see Transplant Patients with Poor Absorption of Sandimmune® (Cyclosporine Capsules USP), below). In some patients, the increase in blood trough concentration is more pronounced and may be of clinical significance.
Until the blood trough concentration attains the pre-conversion value, it is strongly recommended that the cyclosporine blood trough concentration be monitored every 4 to 7 days after conversion to Cyclosporine Capsules USP MODIFIED. In addition, clinical safety parameters such as serum creatinine and blood pressure should be monitored every two weeks during the first two months after conversion. If the blood trough concentrations are outside the desired range and/or if the clinical safety parameters worsen, the dosage of Cyclosporine Capsules USP MODIFIED must be adjusted accordingly.
Transplant Patients with Poor Absorption of Sandimmune® (Cyclosporine Capsules USP)
Patients with lower than expected cyclosporine blood trough concentrations in relation to the oral dose of Sandimmune® (Cyclosporine Capsules USP) may have poor or inconsistent absorption of cyclosporine from Sandimmune® (Cyclosporine Capsules USP). After conversion to Cyclosporine Capsules USP MODIFIED, patients tend to have higher cyclosporine concentrations. Due to the increase in bioavailability of cyclosporine following conversion to Cyclosporine Capsules USP MODIFIED, the cyclosporine blood trough concentration may exceed the target range. Particular caution should be exercised when converting patients to Cyclosporine Capsules USP MODIFIED at doses greater than 10 mg/kg/day. The dose of Cyclosporine Capsules USP MODIFIED should be titrated individually based on cyclosporine trough concentrations, tolerability, and clinical response. In this population the cyclosporine blood trough concentration should be measured more frequently, at least twice a week (daily, if initial dose exceeds 10 mg/kg/day) until the concentration stabilizes within the desired range.
The initial dose of Cyclosporine Capsules USP MODIFIED is 2.5 mg/kg/day, taken twice daily as a divided (BID) oral dose. Salicylates, nonsteroidal anti-inflammatory agents, and oral corticosteroids may be continued (see WARNINGS and PRECAUTIONS, Drug Interactions). Onset of action generally occurs between 4 and 8 weeks. If insufficient clinical benefit is seen and tolerability is good (including serum creatinine less than 30% above baseline), the dose may be increased by 0.5 to 0.75 mg/kg/day after 8 weeks and again after 12 weeks to a maximum of 4 mg/kg/day. If no benefit is seen by 16 weeks of therapy, Cyclosporine Capsules USP MODIFIED therapy should be discontinued.
Dose decreases by 25% to 50% should be made at any time to control adverse events, e.g., hypertension elevations in serum creatinine (30% above patient’s pretreatment level) or clinically significant laboratory abnormalities (see WARNINGS and PRECAUTIONS).
If dose reduction is not effective in controlling abnormalities or if the adverse event or abnormality is severe, Cyclosporine Capsules USP MODIFIED should be discontinued. The same initial dose and dosage range should be used if Cyclosporine Capsules USP MODIFIED is combined with the recommended dose of methotrexate. Most patients can be treated with Cyclosporine Capsules USP MODIFIED doses of 3 mg/kg/day or below when combined with methotrexate doses of up to 15 mg/week (see CLINICAL PHARMACOLOGY, Clinical Trials).
There is limited long-term treatment data. Recurrence of rheumatoid arthritis disease activity is generally apparent within 4 weeks after stopping cyclosporine.
The initial dose of Cyclosporine Capsules USP MODIFIED should be 2.5 mg/kg/day. Cyclosporine Capsules USP MODIFIED should be taken twice daily, as a divided (1.25 mg/kg BID) oral dose. Patients should be kept at that dose for at least 4 weeks, barring adverse events. If significant clinical improvement has not occurred in patients by that time, the patient’s dosage should be increased at 2 week intervals. Based on patient response, dose increases of approximately 0.5 mg/kg/day should be made to a maximum of 4 mg/kg/day.
Dose decreases by 25% to 50% should be made at any time to control adverse events, e.g., hypertension, elevations in serum creatinine (≥ 25% above the patient’s pretreatment level), or clinically significant laboratory abnormalities. If dose reduction is not effective in controlling abnormalities, or if the adverse event or abnormality is severe, Cyclosporine Capsules USP MODIFIED should be discontinued (see Special Monitoring of Psoriasis Patients).
Patients generally show some improvement in the clinical manifestations of psoriasis in 2 weeks. Satisfactory control and stabilization of the disease may take 12 to 16 weeks to achieve. Results of a dose-titration clinical trial with Cyclosporine Capsules USP MODIFIED indicate that an improvement of psoriasis by 75% or more (based on PASI) was achieved in 51% of the patients after 8 weeks and in 79% of the patients after 16 weeks. Treatment should be discontinued if satisfactory response cannot be achieved after 6 weeks at 4 mg/kg/day or the patient’s maximum tolerated dose. Once a patient is adequately controlled and appears stable the dose of Cyclosporine Capsules USP MODIFIED should be lowered, and the patient treated with the lowest dose that maintains an adequate response (this should not necessarily be total clearing of the patient). In clinical trials, cyclosporine doses at the lower end of the recommended dosage range were effective in maintaining a satisfactory response in 60% of the patients. Doses below 2.5 mg/kg/day may also be equally effective.
Upon stopping treatment with cyclosporine, relapse will occur in approximately 6 weeks (50% of the patients) to 16 weeks (75% of the patients). In the majority of patients rebound does not occur after cessation of treatment with cyclosporine. Thirteen cases of transformation of chronic plaque psoriasis to more severe forms of psoriasis have been reported. There were 9 cases of pustular and 4 cases of erythrodermic psoriasis. Long-term experience with Cyclosporine Capsules USP MODIFIED in psoriasis patients is limited and continuous treatment for extended periods greater than one year is not recommended. Alternation with other forms of treatment should be considered in the long-term management of patients with this life long disease.
Blood Concentration Monitoring in Transplant Patients
Transplant centers have found blood concentration monitoring of cyclosporine to be an essential component of patient management. Of importance to blood concentration analysis are the type of assay used, the transplanted organ, and other immunosuppressant agents being administered. While no fixed relationship has been established, blood concentration monitoring may assist in the clinical evaluation of rejection and toxicity, dose adjustments, and the assessment of compliance.
Various assays have been used to measure blood concentrations of cyclosporine. Older studies using a nonspecific assay often cited concentrations that were roughly twice those of the specific assays. Therefore, comparison between concentrations in the published literature and an individual patient concentration using current assays must be made with detailed knowledge of the assay methods employed. Current assay results are also not interchangeable and their use should be guided by their approved labeling. A discussion of the different assay methods is contained in Annals of Clinical Biochemistry 1994;31:420-446. While several assays and assay matrices are available, there is a consensus that parent-compound-specific assays correlate best with clinical events. Of these, HPLC is the standard reference, but the monoclonal antibody RIAs and the monoclonal antibody FPIA offer sensitivity, reproducibility, and convenience. Most clinicians base their monitoring on trough cyclosporine concentrations. Applied Pharmacokinetics, Principles of Therapeutic Drug Monitoring (1992) contains a broad discussion of cyclosporine pharmacokinetics and drug monitoring techniques. Blood concentration monitoring is not a replacement for renal function monitoring or tissue biopsies.
