BOXED WARNING
(What is this?)
WARNING: ESAs INCREASE THE RISK OF DEATH, MYOCARDIAL INFARCTION, STROKE, VENOUS THROMBOEMBOLISM, THROMBOSIS OF VASCULAR ACCESS and TUMOR PROGRESSION OR RECURRENCE
Chronic Kidney Disease [see Warnings and Precautions (5.1)]
- •
- In controlled trials, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when administered erythropoiesis-stimulating agents (ESAs) to target a hemoglobin level of greater than 11 g/dL.
- •
- No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks.
- •
- Use the lowest Mircera dose sufficient to reduce the need for red blood cell (RBC) transfusions.
Cancer [see Warnings and Precautions (5.2)]
- •
- Mircera is not indicated and is not recommended for the treatment of anemia due to cancer chemotherapy. A dose-ranging study of Mircera was terminated early because of more deaths among patients receiving Mircera than another ESA.
- •
- ESAs have shown shortened overall survival and/or increased the risk of tumor progression or recurrence in clinical studies in patients with breast, non-small cell lung, head and neck, lymphoid, and cervical cancers.
-
1 INDICATIONS AND USAGE
1.1 Anemia Due to Chronic Kidney Disease
Mircera is indicated for the treatment of anemia associated with chronic kidney disease (CKD) in:
- •
- adult patients on dialysis and adult patients not on dialysis.
- •
- pediatric patients 3 months to 17 years of age on dialysis or not on dialysis who are converting from another ESA after their hemoglobin level was stabilized with an ESA.
Limitations of Use
Mircera is not indicated and is not recommended:
- •
- In the treatment of anemia due to cancer chemotherapy [see Warnings and Precautions (5.2)].
- •
- As a substitute for RBC transfusions in patients who require immediate correction of anemia [see Clinical Pharmacology (12.2)].
Mircera has not been shown to improve symptoms, physical functioning, or health-related quality of life.
-
2 DOSAGE AND ADMINISTRATION
2.1 Important Dosing Information
Evaluation of Iron Stores and Nutritional Factors
Evaluate the iron status in all patients before and during treatment. Administer supplemental iron therapy when serum ferritin is less than 100 mcg/L or when serum transferrin saturation is less than 20%. The majority of patients with CKD will require supplemental iron during the course of ESA therapy.
Monitoring of Response to Therapy
Correct or exclude other causes of anemia (e.g., vitamin deficiency, metabolic or chronic inflammatory conditions, bleeding, etc.) before initiating Mircera [see Warnings and Precautions (5.9)]. Following initiation of therapy and after each dose adjustment, monitor hemoglobin weekly until the hemoglobin level is stable and sufficient to minimize the need for RBC transfusion.
Individualization of Dosing
Individualize and use the lowest dose of Mircera sufficient to reduce the need for RBC transfusions [see Warnings and Precautions (5.1)]. In controlled trials, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when administered erythropoiesis-stimulating agents (ESAs) to target a hemoglobin level of greater than 11 g/dL for adult patients. No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks. Physicians and patients should weigh the possible benefits of decreasing transfusions against the increased risks of death and other serious cardiovascular adverse events [see Boxed Warning and Clinical Studies (14)].
2.2 For Adult Patients with CKD
Prefilled syringes are not designed for administration of partial doses. Round doses to the closest dose achievable with the prefilled syringes.
When initiating or adjusting therapy, monitor hemoglobin levels at least weekly until stable, then monitor at least monthly. When adjusting therapy consider hemoglobin rate of rise, rate of decline, ESA responsiveness and hemoglobin variability. A single hemoglobin excursion may not require a dosing change.
- •
- Do not increase the dose more frequently than once every 4 weeks. Decreases in dose can occur more frequently. Avoid frequent dose adjustments.
- •
- If the hemoglobin rises rapidly (e.g., more than 1 g/dL in any 2-week period), reduce the dose of Mircera by approximately 25% to the closest dose achievable with the prefilled syringes to reduce rapid responses.
- •
- If the hemoglobin continues to rise following a dose reduction, discontinue Mircera until the hemoglobin level begins to decrease, at which point therapy should be restarted with a dose that is approximately 25% below the previously administered dose.
- •
- For patients who do not respond adequately, if the hemoglobin has not increased by more than 1 g/dL after 4 weeks of therapy, increase the dose by approximately 25% to the closest dose achievable with the prefilled syringes.
- •
- For patients who do not respond adequately over a 12-week escalation period, increasing the Mircera dose further is unlikely to improve response and may increase risks. Use the lowest dose that will maintain a hemoglobin level sufficient to reduce the need for RBC transfusions. Evaluate other causes of anemia. Discontinue Mircera if responsiveness does not improve.
Administer Mircera either intravenously or subcutaneously. When administered subcutaneously, Mircera should be injected in the abdomen, arm or thigh.
For Adult Patients with CKD on dialysis:
- •
- Initiate Mircera treatment when the hemoglobin level is less than 10 g/dL.
- •
- If the hemoglobin level approaches or exceeds 11 g/dL, reduce or interrupt the dose of Mircera.
- •
- The recommended starting dose of Mircera for the treatment of anemia in adult CKD patients who are not currently treated with an ESA is 0.6 mcg/kg body weight administered once every two weeks as a single intravenous or subcutaneous injection. The intravenous route is recommended for patients receiving hemodialysis because the intravenous route may be less immunogenic [see Adverse Reactions (6.2)].
- •
- Once the hemoglobin has been stabilized, Mircera may be administered once monthly using a dose that is twice that of the every-two-week dose and subsequently titrated as necessary.
For Adult Patients with CKD not on dialysis:
- •
- Consider initiating Mircera treatment only when the hemoglobin level is less than 10 g/dL and the following considerations apply:
- o
- The rate of hemoglobin decline indicates the likelihood of requiring a RBC transfusion and,
- o
- Reducing the risk of alloimmunization and/or other RBC transfusion-related risks is a goal.
- •
- If the hemoglobin level exceeds 10 g/dL, reduce or interrupt the dose of Mircera, and use the lowest dose of Mircera sufficient to reduce the need for RBC transfusions.
- •
- The recommended starting dose of Mircera for the treatment of anemia in adult CKD patients who are not currently treated with an ESA is 1.2 mcg/kg body weight administered once every month as a single subcutaneous injection. Alternatively, a starting dose of 0.6 mcg/kg body weight may be administered once every two weeks as a single intravenous or subcutaneous injection.
- •
- Once the hemoglobin has been stabilized, Mircera may be administered once monthly using a dose that is twice that of the every-two-week dose and subsequently titrated as necessary.
Refer patients who self-administer Mircera to the Instructions for Use [see Patient Counseling Information (17)].
Conversion from Epoetin alfa or Darbepoetin alfa to Mircera in Adult Patients with CKD
Mircera can be administered once every two weeks or once monthly to patients whose hemoglobin has been stabilized by treatment with an ESA (see Table 1). The dose of Mircera, given as a single intravenous or subcutaneous injection, should be based on the total weekly ESA dose at the time of conversion.

2.3 For Pediatric Patients with CKD
Conversion from Epoetin alfa or Darbepoetin alfa to Mircera in Pediatric Patients with CKD
Pre-filled syringes are not designed for administration of partial doses. Pediatric patients requiring a dose of less than 30 mcg of Mircera should not be treated with Mircera.
In patients less than 6 years of age, maintain the same route of administration as the previous ESA when switching from another ESA to Mircera.
Administer Mircera once every 4 weeks as an intravenous or subcutaneous injection to pediatric patients (ages 3 months to 17 years) whose hemoglobin level has been stabilized by treatment with an ESA. The starting dose of Mircera is calculated based on the total weekly ESA dose at the time of conversion. Refer to Table 2 for the dose of Mircera corresponding to the available commercial prefilled syringe strengths.

Decrease dose by approximately 25% to the closest dose achievable with the prefilled syringes
If Hb exceeds 12 g/dL and continues to increase following a dose reduction
Stop doses until Hb is less than 12.0 g/dL. Resume dose at approximately 25% below previous dose to the closest dose achievable with the prefilled syringes at next scheduled dosing day.
2.4 Preparation and Administration of Mircera
Mircera is packaged as single-dose prefilled syringes. Mircera contains no preservatives. Discard any unused portion. Do not pool unused portions from the prefilled syringes. Do not use the prefilled syringe more than once.
Always store Mircera prefilled syringes in their original cartons. Vigorous shaking or prolonged exposure to light should be avoided.
Do not mix Mircera with any parenteral solution.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Do not use any prefilled syringes exhibiting particulate matter or a coloration other than colorless to slightly yellowish.
For administration using the prefilled syringe, the plunger must be fully depressed during injection in order for the needle guard to activate. Following administration, remove the needle from the injection site and then release the plunger to allow the needle guard to move up until the entire needle is covered.
Children and adolescents less than 17 years of age should not self-inject Mircera. Intravenous and subcutaneous administration should be performed by a healthcare professional or adult caregiver.
See “Instructions for Use” for complete instructions on the preparation and administration of Mircera. Examine each prefilled syringe for the expiration date. Do not use Mircera after the expiration date.
- 3 DOSAGE FORMS AND STRENGTHS
-
4 CONTRAINDICATIONS
Mircera is contraindicated in patients with:
- •
- Uncontrolled hypertension [see Warnings and Precautions (5.3)]
- •
- Pure red cell aplasia (PRCA) that begins after treatment with Mircera or other erythropoietin protein drugs [see Warnings and Precautions (5.6)]
- •
- History of serious or severe allergic reactions to Mircera (e.g., anaphylactic reactions, angioedema, bronchospasm, skin rash, and urticaria) [see Warnings and Precautions (5.7, 5.8)].
-
5 WARNINGS AND PRECAUTIONS
5.1 Increased Mortality, Myocardial Infarction, Stroke, and Thromboembolism
- •
- In controlled clinical trials of patients with CKD comparing higher hemoglobin targets (13 to 14 g/dL) to lower targets (9 to 11.3 g/dL), ESAs increased the risk of death, myocardial infarction, stroke, congestive heart failure, thrombosis of hemodialysis vascular access, and other thromboembolic events in the higher target groups.
- •
- Using ESAs to target a hemoglobin level of greater than 11 g/dL increases the risk of serious adverse cardiovascular reactions and has not been shown to provide additional benefit [see Clinical Studies (14)]. Use caution in patients with coexistent cardiovascular disease and stroke [see Dosage and Administration (2.2)]. Patients with CKD and an insufficient hemoglobin response to ESA therapy may be at even greater risk for cardiovascular reactions and mortality than other patients. A rate of hemoglobin rise of greater than 1 g/dL over 2 weeks may contribute to these risks.
- •
- In controlled clinical trials of patients with cancer, ESAs increased the risks for death and serious adverse cardiovascular reactions. These adverse reactions included myocardial infarction and stroke.
- •
- In controlled clinical trials, ESAs increased the risk of death in patients undergoing coronary artery bypass graft surgery (CABG) and the risk of deep venous thrombosis (DVT) in patients undergoing orthopedic procedures.
The design and overall results of the 3 large trials comparing higher and lower hemoglobin targets are shown in Table 4 (Normal Hematocrit Study (NHS), Correction of Hemoglobin Outcomes in Renal Insufficiency (CHOIR) and Trial to Reduce Cardiovascular Events with Aranesp® Therapy (TREAT)).

Patients with Chronic Kidney Disease
NHS: A prospective, randomized, open-label study of 1265 patients with chronic kidney disease on dialysis with documented evidence of congestive heart failure or ischemic heart disease was designed to test the hypothesis that a higher target hematocrit (Hct) would result in improved outcomes compared with a lower target Hct. In this study, patients were randomized to epoetin alfa treatment targeted to a maintenance hemoglobin of either 14 ± 1 g/dL or 10 ± 1 g/dL. The trial was terminated early with adverse safety findings of higher mortality in the high hematocrit target group. Higher mortality (35% vs. 29%) was observed for the patients randomized to a target hemoglobin of 14 g/dL than for the patients randomized to a target hemoglobin of 10 g/dL. For all-cause mortality, the HR=1.27; 95% CI (1.04, 1.54); p=0.018. The incidence of nonfatal myocardial infarction, vascular access thrombosis, and other thrombotic events was also higher in the group randomized to a target hemoglobin of 14 g/dL.
CHOIR: In a randomized prospective trial, 1432 patients with anemia due to CKD who were not undergoing dialysis were assigned to epoetin alfa treatment targeting a maintenance hemoglobin concentration of 13.5 g/dL or 11.3 g/dL. The trial was terminated early with adverse safety findings. A major cardiovascular event (death, myocardial infarction, stroke, or hospitalization for congestive heart failure) occurred among 125 (18%) of the 715 patients in the higher hemoglobin group compared to 97 (14%) among the 717 patients in the lower hemoglobin group (HR 1.3, 95% CI: 1.0, 1.7 p=0.03).
TREAT: A randomized, double-blind, placebo-controlled, prospective trial of 4038 patients with: CKD not on dialysis (eGFR of 20 – 60 mL/min), anemia (hemoglobin levels ≤ 11 g/dL), and type 2 diabetes mellitus, patients were randomized to receive either darbepoetin alfa treatment or a matching placebo. Placebo group patients also received darbepoetin alfa when their hemoglobin levels were below 9 g/dL. The trial objectives were to demonstrate the benefit of darbepoetin alfa treatment of the anemia to a target hemoglobin level of 13 g/dL, when compared to a “placebo” group, by reducing the occurrence of either of two primary endpoints:
(1) a composite cardiovascular endpoint of all-cause mortality or a specified cardiovascular event (myocardial ischemia, CHF, MI, and CVA) or (2) a composite renal endpoint of all-cause mortality or progression to end stage renal disease. The overall risks for each of the two primary endpoints (the cardiovascular composite and the renal composite) were not reduced with darbepoetin alfa treatment (see Table 4), but the risk of stroke was increased nearly two-fold in the darbepoetin alfa-treated group vs. the placebo group: annualized stroke rate 2.1% vs. 1.1%, respectively, HR 1.92; 95% CI: 1.38, 2.68; p less than 0.001. The relative risk of stroke was particularly high in patients with a prior stroke: annualized stroke rate 5.2% in the darbepoetin alfa-treated group and 1.9% in the placebo group, HR 3.07; 95% CI: 1.44, 6.54. Also, among darbepoetin alfa-treated subjects with a past history of cancer, there were more deaths due to all causes and more deaths adjudicated as due to cancer, in comparison with the control group.Patients with Cancer
An increased incidence of thromboembolic reactions, some serious and life-threatening, occurred in patients with cancer treated with ESAs.
In a randomized, placebo-controlled study (Study 1 in Table 5 [see Warnings and Precautions (5.2)]) of 939 women with metastatic breast cancer receiving chemotherapy, patients received either weekly epoetin alfa or placebo for up to a year. This study was designed to show that survival was superior when epoetin alfa was administered to prevent anemia (maintain hemoglobin levels between 12 and 14 g/dL or hematocrit between 36% and 42%). This study was terminated prematurely when interim results demonstrated a higher mortality at 4 months (8.7% vs. 3.4%) and a higher rate of fatal thrombotic reactions (1.1% vs. 0.2%) in the first 4 months of the study among patients treated with epoetin alfa. Based on Kaplan-Meier estimates, at the time of study termination, the 12-month survival was lower in the epoetin alfa group than in the placebo group (70% vs. 76%; HR 1.37, 95% CI: 1.07, 1.75; p = 0.012).
Patients Having Surgery
Mircera is not approved for reduction of RBC transfusions in patients scheduled for surgical procedures.
An increased incidence of deep vein thrombosis (DVT) in patients receiving epoetin alfa undergoing surgical orthopedic procedures has been observed. In a randomized controlled study (referred to as the “SPINE” study), 681 adult patients, not receiving prophylactic anticoagulation and undergoing spinal surgery, received epoetin alfa and standard of care (SOC) treatment, or SOC treatment alone. Preliminary analysis showed a higher incidence of DVT, determined by either Color Flow Duplex Imaging or by clinical symptoms, in the epoetin alfa group [16 patients (4.7%)] compared to the SOC group [7 patients (2.1%)]. In addition, 12 patients in the epoetin alfa group and 7 patients in the SOC group had other thrombotic vascular events.
Increased mortality was observed in a randomized placebo-controlled study of epoetin alfa in adult patients who were undergoing coronary artery bypass surgery (7 deaths in 126 patients randomized to epoetin alfa vs. no deaths among 56 patients receiving placebo). Four of these deaths occurred during the period of study drug administration and all four deaths were associated with thrombotic events.
5.2 Increased Mortality and/or Increased Risk of Tumor Progression or Recurrence in Patients with Cancer
Mircera is not indicated and is not recommended for use in the treatment of anemia due to cancer chemotherapy. A dose-ranging trial of Mircera in 153 patients who were undergoing chemotherapy for non-small cell lung cancer was terminated prematurely because more deaths occurred among patients receiving Mircera than another ESA.
ESAs resulted in decreased locoregional control/progression-free survival and/or overall survival (see Table 5). These findings were observed in studies of patients with advanced head and neck cancer receiving radiation therapy (Studies 5 and 6), in patients receiving chemotherapy for metastatic breast cancer (Study 1) or lymphoid malignancy (Study 2), and in patients with non-small cell lung cancer or various malignancies who were not receiving chemotherapy or radiotherapy (Studies 7 and 8).

Decreased Overall Survival
Cancer Study 1 (the “BEST” study) was previously described [see Warnings and Precautions (5.1)]. Mortality at 4 months (8.7% vs. 3.4%) was significantly higher in the epoetin alfa arm. The most common investigator-attributed cause of death within the first 4 months was disease progression; 28 of 41 deaths in the epoetin alfa arm and 13 of 16 deaths in the placebo arm were attributed to disease progression. Investigator assessed time to tumor progression was not different between the two groups. Survival at 12 months was significantly lower in the epoetin alfa arm (70% vs. 76%, HR 1.37, 95% CI: 1.07, 1.75; p=0.012).
Cancer Study 2 was a Phase 3, double-blind, randomized (darbepoetin alfa vs. placebo) study conducted in 344 anemic patients with lymphoid malignancy receiving chemotherapy. With a median follow-up of 29 months, overall mortality rates were significantly higher among patients randomized to darbepoetin alfa as compared to placebo (HR 1.36, 95% CI: 1.02, 1.82).
Cancer Study 7 was a Phase 3, multicenter, randomized (epoetin alfa vs. placebo), double-blind study, in which patients with advanced non-small cell lung cancer receiving only palliative radiotherapy or no active therapy were treated with epoetin alfa to achieve and maintain hemoglobin levels between 12 and 14 g/dL. Following an interim analysis of 70 of 300 patients planned, a significant difference in survival in favor of the patients on the placebo arm of the trial was observed (median survival 63 vs. 129 days; HR 1.84; p=0.04).
Cancer Study 8 was a Phase 3, double-blind, randomized (darbepoetin alfa vs. placebo), 16-week study in 989 anemic patients with active malignant disease, neither receiving nor planning to receive chemotherapy or radiation therapy. There was no evidence of a statistically significant reduction in proportion of patients receiving RBC transfusions. The median survival was shorter in the darbepoetin alfa treatment group (8 months) compared with the placebo group (10.8 months); HR 1.30, 95% CI: 1.07, 1.57.
Decreased Progression-Free Survival and Overall Survival
Cancer Study 3 (the “PREPARE” study) was a randomized controlled study in which darbepoetin alfa was administered to prevent anemia conducted in 733 women receiving neo-adjuvant breast cancer treatment. A final analysis was performed after a median follow-up of approximately 3 years at which time the survival rate was lower (86% vs. 90%, HR 1.42, 95% CI: 0.93, 2.18) and relapse-free survival rate was lower (72% vs. 78%, HR 1.33, 95% CI: 0.99, 1.79) in the darbepoetin alfa-treated arm compared to the control arm.
Cancer Study 4 (protocol GOG 191) was a randomized controlled study that enrolled 114 of a planned 460 cervical cancer patients receiving chemotherapy and radiotherapy. Patients were randomized to receive epoetin alfa to maintain hemoglobin between 12 and 14 g/dL or to transfusion support as needed. The study was terminated prematurely due to an increase in thromboembolic events in epoetin alfa-treated patients compared to control (19% vs. 9%). Both local recurrence (21% vs. 20%) and distant recurrence (12% vs. 7%) were more frequent in epoetin alfa-treated patients compared to control. Progression-free survival at 3 years was lower in the epoetin alfa-treated group compared to control (59% vs. 62%, HR 1.06, 95% CI: 0.58, 1.91). Overall survival at 3 years was lower in the epoetin alfa-treated group compared to control (61% vs. 71%, HR 1.28, 95% CI: 0.68, 2.42).
Cancer Study 5 (the “ENHANCE” study) was a randomized controlled study in 351 head and neck cancer patients where epoetin beta or placebo was administered to achieve target hemoglobins of 14 and 15 g/dL for women and men, respectively. Locoregional progression-free survival was significantly shorter in patients receiving epoetin beta (HR 1.62, 95% CI: 1.22, 2.14, p=0.0008) with a median of 406 days epoetin beta vs. 745 days placebo. Overall survival was significantly shorter in patients receiving epoetin beta (HR 1.39, 95% CI: 1.05, 1.84; p=0.02).
Decreased Locoregional Control
Cancer Study 6 (DAHANCA 10) was conducted in 522 patients with primary squamous cell carcinoma of the head and neck receiving radiation therapy randomized to darbepoetin alfa with radiotherapy or radiotherapy alone. An interim analysis on 484 patients demonstrated that locoregional control at 5 years was significantly shorter in patients receiving darbepoetin alfa (RR 1.44, 95% CI: 1.06, 1.96; p=0.02). Overall survival was shorter in patients receiving darbepoetin alfa (RR 1.28, 95% CI: 0.98, 1.68; p=0.08).
5.3 Hypertension
Mircera is contraindicated in patients with uncontrolled hypertension.
In Mircera clinical studies, approximately 27% of patients with CKD, including patients on dialysis and patients not on dialysis, required intensification of antihypertensive therapy. Hypertensive encephalopathy and/or seizures have been observed in patients with CKD treated with Mircera [see Warnings and Precautions (5.4)].
Appropriately control hypertension prior to initiation of and during treatment with Mircera. Reduce or withhold Mircera if blood pressure becomes difficult to control. Advise patients of the importance of compliance with antihypertensive therapy and dietary restrictions [see Patient Counseling Information (17)].
5.4 Seizures
Seizures have occurred in patients participating in Mircera clinical studies. During the first several months following initiation of Mircera, monitor patients closely for premonitory neurologic symptoms. Advise patients to contact their healthcare practitioner for new-onset seizures, premonitory symptoms, or change in seizure frequency.
5.5 Lack or Loss of Hemoglobin Response to Mircera
For lack or loss of hemoglobin response to Mircera, initiate a search for causative factors (e.g., iron deficiency, infection, inflammation, bleeding).
If typical causes of lack or loss of hemoglobin response are excluded, evaluate for PRCA [see Warnings and Precautions (5.6)]. In the absence of PRCA, follow dosing recommendations for management of patients with an insufficient response to Mircera therapy [see Dosage and Administration (2.1)].
5.6 Pure Red Cell Aplasia
Cases of PRCA and of severe anemia, with or without other cytopenias that arise following the development of neutralizing antibodies to erythropoietin have been reported in the postmarketing setting in patients treated with Mircera. This has been reported predominantly in patients with CKD receiving ESAs by subcutaneous administration. PRCA was not observed in clinical studies of Mircera.
PRCA has also been reported in patients receiving ESAs for anemia related to hepatitis C treatment (an indication for which Mircera is not approved).
If severe anemia and low reticulocyte count develop during treatment with Mircera, withhold Mircera and evaluate patients for neutralizing antibodies to erythropoietin [see Warnings and Precautions (5.5)]. Serum samples should be obtained at least a month after the last Mircera administration to prevent interference of Mircera with the assay. Contact Vifor at 1-800-576-8295 to perform assays for binding and neutralizing antibodies. Permanently discontinue Mircera in patients who develop PRCA following treatment with Mircera or other erythropoietin protein drugs. Do not switch patients to other ESAs as antibodies may cross-react [see Adverse Reactions (6.2)].
5.7 Serious Allergic Reactions
Serious allergic reactions, including anaphylactic reactions, angioedema, bronchospasm, tachycardia, pruritus skin rash and urticaria have been reported in patients treated with Mircera. If a serious allergic or anaphylactic reaction occurs due to Mircera, immediately and permanently discontinue Mircera and administer appropriate therapy.
5.8 Severe Cutaneous Reactions
Blistering and skin exfoliation reactions including Erythema multiforme and Stevens-Johnson Syndrome (SJS)/Toxic Epidermal Necrolysis (TEN), have been reported in patients treated with ESAs (including Mircera) in the postmarketing setting. Discontinue Mircera therapy immediately if a severe cutaneous reaction, such as SJS/TEN, is suspected.

6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of Mircera cannot be directly compared to rates in the clinical trials of other drugs and may not reflect the rates observed in practice.
Adult Patients
The data described below reflect exposure to Mircera in 2737 patients, including 1451 exposed for 6 months and 1144 exposed for greater than one year. Mircera was studied primarily in active-controlled studies (n=1789 received Mircera, and n=948 received another ESA) and in long-term follow up studies. The population was 18 to 92 years of age, 58% male, and the percentage of Caucasian, Black (including African Americans), Asian and Hispanic patients were 73%, 20%, 5%, and 9%, respectively. Approximately 85% of the patients were receiving dialysis. Most patients received Mircera using dosing regimens of once every two or four weeks, administered subcutaneously or intravenously.
The most commonly reported adverse reactions in ≥10% of patients were hypertension [see Warnings and Precautions (5.3)], diarrhea, and nasopharyngitis. The most common adverse reactions that led to treatment discontinuation in the Mircera clinical studies were: hypertension, coronary artery disease, anemia, concomitant termination of other CKD therapy and septic shock. Some of the adverse reactions reported are typically associated with CKD, or recognized complications of dialysis, and may not necessarily be attributable to Mircera therapy. Adverse reaction rates did not importantly differ between patients receiving Mircera or another ESA.
Table 6 summarizes the most frequent adverse reactions (≥5%) in patients treated with Mircera.

In the controlled trials, the rates of serious adverse reactions did not importantly differ between patients receiving Mircera and another ESA (38% vs. 42%) except for the occurrence of serious gastrointestinal hemorrhage (1.2% vs. 0.2%). Serious hemorrhagic adverse reactions of all types occurred among 5% and 4% of patients receiving Mircera or another ESA, respectively.
Pediatric Patients
In an open-label, multiple dose study, 64 pediatric patients (ages 5 to 17 years) with CKD who were on hemodialysis and who had stable hemoglobin levels while previously receiving another ESA (epoetin alfa/beta or darbepoetin alfa) were then converted to Mircera administered intravenously once every 4 weeks for 20 weeks (core study period). Patients who completed the core study period with hemoglobin within ± 1 g/dL of their baseline hemoglobin and within the target range of 10 to 12 g/dL were eligible to enter an optional 52-week safety extension period (total duration of treatment, up to 73 weeks). In the extension period, 25 (out of 37) patients were treated for at least an additional 5 months. During the whole study (core study and safety extension), 33 patients were exposed to Mircera for at least 6 months and 19 were exposed for greater than 15 months.
All reported adverse reactions regardless of causality (more than 5% incidence) in the pediatric population included headache (22%), nasopharyngitis (22%), hypertension (19%), vomiting (11%), bronchitis (9%), abdominal pain (8%), arteriovenous fistula thrombosis (6%), cough (6%), device related infection (6%), hyperkalemia (6%), pharyngitis (6%), pyrexia (6%), thrombocytopenia (6%), and thrombosis in device (6%).
A second open-label, single-arm, multicenter study was conducted to ascertain the optimal starting dose of Mircera given subcutaneously for the maintenance treatment of anemia in 40 pediatric patients (ages 3 months to 17 years) with CKD on dialysis or not on dialysis. Patients completing the 20 weeks of treatment (core period) with Hb within ±1 g/dL of their baseline Hb and within the target range of 10 to 12 g/dL, were eligible to enter an optional 24-week safety extension period. Mircera was administered subcutaneously once every 4 weeks for the duration of the study. Thirty-eight (38) patients were exposed to Mircera for 20 weeks, and 21 patients were exposed to Mircera for 44 weeks. Overall, the pattern of adverse events reported was similar to the established safety profile of Mircera in adult patients and the patients aged 5 to 17 years in the previous intravenous study.
6.2 Postmarketing Experience
The following adverse reactions have been identified during post-approval use of Mircera. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Hypersensitivity
Stevens-Johnson syndrome/toxic epidermal necrolysis has been reported [see Warnings and Precautions (5.7)].
Pure Red Cell Aplasia (PRCA)
Cases of PRCA and of severe anemia, with or without other cytopenias that arise following the development of neutralizing antibodies to erythropoietin have been reported in patients treated with Mircera [see Warnings and Precautions (5.6)].

8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
Available data from a small number of published case reports and postmarketing experience with Mircera use in pregnancy are insufficient to identify a drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Chronic kidney disease is associated with maternal and embryo-fetal risks (see Clinical Considerations). In animal reproduction studies, administration of methoxy polyethylene glycol-epoetin beta to rats and rabbits during pregnancy and lactation adversely affected offspring at doses 17-fold and greater than the recommended human dose (see Data).
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Clinical Considerations
Disease Associated Maternal and/or Embryo-Fetal Risk
Pregnancy in women with chronic kidney disease has been associated with adverse outcomes including hypertension, pre-eclampsia, miscarriage, premature birth, low-birth-weight, polyhydramnios, and intrauterine growth restriction.
Data
When methoxy polyethylene glycol-epoetin beta was administered subcutaneously to rats and rabbits during gestation (including the period of organogenesis), bone malformation was observed in both species at 50 mcg/kg once every three days (corresponding to 500 mcg/kg/month or 417-fold the recommended human dose) in studies of embryo-fetal development. This effect was observed as missing caudal vertebrae resulting in a thread-like tail in one rat fetus, absent first digit metacarpal and phalanx on each forelimb resulting in absent pollex in one rabbit fetus, and fused fourth and fifth cervical vertebrae centra in another rabbit fetus. Dose-related reduction in fetal weights was observed in both rats and rabbits. At doses 5 mcg/kg once every three days and higher, corresponding to 50 mcg/kg/month or 42-fold the recommended human dose, methoxy polyethylene glycol-epoetin beta caused exaggerated pharmacodynamic effects in dams.
Once-weekly doses of methoxy polyethylene glycol-epoetin beta up to 50 mcg/kg/dose (corresponding to 200 mcg/kg/month or 167-fold the recommended human dose) given to pregnant and lactating rats did not adversely affect pregnancy parameters, natural delivery or litter observations in a study of pre-and postnatal development. Increased deaths and significant reduction in the growth rate of the F1 generation were observed during lactation and early post weaning period at 20 and 50 mcg/kg/dose, corresponding to 80 and 200 mcg/kg/month or 67- and 167-fold the recommended human dose. A significant reduction in the growth rate of the F1 generation was evident already at 5 mcg/kg/dose, corresponding to 20 mcg/kg/month or 17-fold the recommended human dose. However, no remarkable effect on reflex, physical and cognitive development or reproductive performance was observed in F1 generation of any dose groups.
The dose level not causing any adverse effect on dams or offspring was not determined.
8.2 Lactation
Risk Summary
There are no data on the presence of methoxy polyethylene glycol-epoetin beta in human milk, the effects on the breastfed child, or the effects on milk production. However, endogenous erythropoietin is present in human milk. In rats, methoxy polyethylene glycol-epoetin beta was present in maternal milk (see Data). When a drug is present in animal milk, it is likely that the drug will be present in human milk. The lack of clinical data during lactation precludes a clear determination of the risk of Mircera to a child during lactation. Therefore, the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Mircera and any potential adverse effects on the breastfed child from Mircera or from the underlying maternal condition.
Data
A dose of methoxy polyethylene glycol-epoetin beta approximately 3-fold greater than the recommended human dose was administered to lactating rats. Methoxy polyethylene glycol-epoetin beta was detected in maternal milk 4 hours postdose and reached maximum concentration 48 hours postdose. The maximum amount of methoxy polyethylene glycol-epoetin beta in milk was about 10-fold lower than in serum. The concentration of drug in animal milk does not necessarily predict the concentration of drug in human milk.
8.4 Pediatric Use
The safety and effectiveness of intravenous and subcutaneous Mircera for the treatment of anemia due to CKD have been established in pediatric patients 3 months to 17 years of age on dialysis and not on dialysis who are converting from another ESA after their hemoglobin level was stabilized with an ESA. The use of Mircera in this pediatric age group is supported by evidence from adequate and well-controlled studies of Mircera in adults, a dose-finding study in 64 pediatric patients 5 to 17 years of age with CKD on hemodialysis and a subcutaneous dose-finding study in 40 patients 3 months to 17 years of age with CKD on dialysis or not on dialysis. The adverse reaction profile observed in pediatric patients was consistent with the safety profile found in adults. The safety and effectiveness of Mircera have not been established in patients less than 3 months of age [see Adverse Reactions (6.1) and Clinical Studies (14.2)].
The safety and effectiveness of Mircera have not been established for treatment of anemia in pediatric patients whose hemoglobin level has not been previously stabilized by treatment with an ESA.
8.5 Geriatric Use
Clinical studies of Mircera did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses 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.
-
9 DRUG ABUSE AND DEPENDENCE
9.1 Controlled Substance
Mircera contains methoxy polyethylene glycol-epoetin beta which is not a controlled substance.
9.2 Abuse
Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects. Abuse of Mircera may be seen in athletes for the effects on erythropoiesis. Abuse of drugs that increase erythropoiesis, such as Mircera, by healthy persons may lead to life-threatening cardiovascular complications (e.g., stroke, myocardial infarction, and thromboembolism).
In animal studies, methoxy polyethylene glycol-epoetin beta showed low distribution into the CNS which did not cause behavioral effects consistent with CNS activity.
-
10 OVERDOSAGE
Mircera overdosage can elevate hemoglobin levels above the desired level, which should be managed with discontinuation or reduction of Mircera dosage and/or with phlebotomy, as clinically indicated [see Pharmacodynamics (12.2)]. Cases of severe hypertension have been observed following overdose with ESAs [see Warnings and Precautions (5.3)].
-
11 DESCRIPTION
Methoxy polyethylene glycol-epoetin beta, is an ESA which differs from erythropoietin through formation of a chemical bond between either the N-terminal amino group or the ε-amino group of any lysine present in erythropoietin, predominantly Lys52 and Lys45, and methoxy polyethylene glycol (PEG) butanoic acid (approximately 30,000 daltons). This results in a total molecular weight of approximately 60,000 daltons. Methoxy polyethylene glycol-epoetin beta is produced in Chinese hamster ovary (CHO) cells using recombinant DNA technology.
Mircera is formulated as a sterile, preservative-free protein solution for intravenous or subcutaneous administration. Mircera (methoxy polyethylene glycol-epoetin beta) injection is supplied in prefilled syringes (30 mcg, 50 mcg, 75 mcg, 100 mcg, 120 mcg, 150 mcg, 200 mcg, or 250 mcg in 0.3 mL) and formulated in an aqueous solution containing mannitol (9 mg), methionine (0.447 mg), poloxamer 188 (0.03 mg), sodium phosphate monobasic monohydrate (0.414 mg), and sodium sulfate (1.704 mg). Mircera 360 mcg in 0.6 mL is formulated in an aqueous solution containing mannitol (18 mg), methionine (0.894 mg), poloxamer 188 (0.06 mg), sodium phosphate monobasic monohydrate (0.828 mg), and sodium sulfate (3.408 mg). The solution is clear, colorless to slightly yellowish and the pH is 6.2 ± 0.2.
-
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Mircera is an erythropoietin receptor activator with greater activity in vivo as well as increased half-life, in contrast to erythropoietin. A primary growth factor for erythroid development, erythropoietin is produced in the kidney and released into the bloodstream in response to hypoxia. In responding to hypoxia, erythropoietin interacts with erythroid progenitor cells to increase red cell production. Production of endogenous erythropoietin is impaired in patients with CKD and erythropoietin deficiency is the primary cause of their anemia.
12.2 Pharmacodynamics
Following a single-dose of Mircera in adult patients with CKD, the onset of hemoglobin increase (defined as an increase more than 0.4 g/dL from baseline) was observed 7 to 15 days following initial dose administration [see Dosage and Administration (2.2)].
12.3 Pharmacokinetics
The pharmacokinetics of methoxy polyethylene glycol-epoetin beta were studied in adult anemic patients with CKD including patients on dialysis and those not on dialysis. Parameters are presented as the geometric mean [% coefficient of variation (%CV)] unless otherwise specified.
Methoxy polyethylene glycol-epoetin beta did not accumulate following administration every four weeks. However, when Mircera was administered every 2 weeks, serum concentrations at steady state increased by 12%. Multiple dosing had no effect on clearance, volume of distribution or bioavailability of methoxy polyethylene glycol-epoetin beta.
Absorption
Following the subcutaneous administration of Mircera, the maximum serum concentrations of methoxy polyethylene glycol-epoetin beta were observed at a median [min, max] time of 72 [24, 192] hours. The absolute bioavailability of Mircera after the subcutaneous administration was 62%.
Distribution
The volume of distribution at steady state was 61 [46%] mL/kg.
Elimination
Following an intravenous administration of Mircera 0.4 mcg/kg body weight to patients with CKD receiving peritoneal dialysis, the observed terminal half-life was 119 [55%] hours, and the total systemic clearance was 0.47 [35%] mL/hr/kg. Following a subcutaneous administration of Mircera 0.8 mcg/kg to CKD patients receiving peritoneal dialysis, the terminal half-life was 124 [57%] hours.
Specific Populations
The pharmacokinetics of methoxy polyethylene glycol-epoetin beta were not altered by age (range: 6-89 years), gender, race, severe hepatic impairment (Child-Pugh Class C), site of subcutaneous injection (abdomen, arm or thigh), or the use of dialysis.
Pediatric Patients
A population pharmacokinetic analysis was performed with data from 103 pediatric patients ages 6 months to 17 years and 524 adult patients. Pediatric patients received Mircera intravenously (N=63, all on hemodialysis) or subcutaneously (total N=40, n=17 on pre-dialysis, n=18 on peritoneal dialysis and n=5 on hemodialysis). The covariate analysis showed a positive body weight effect on clearance (CL) and volume of distribution (V), and a positive age effect on V. Once those covariate effects were taken into account together with the addition of a pediatric subcutaneous bioavailability of 67%, compared to 31% in adults, no differences could be observed in the pharmacokinetic properties of Mircera in pediatric patients compared to adult patients.
12.6 Immunogenicity
The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of Mircera or of other methoxy polyethylene glycol-epoetin beta products.
Neutralizing antibodies to Mircera that cross-react with endogenous erythropoietin and other ESAs can result in PRCA or severe anemia (with or without other cytopenias) [see Warnings and Precautions (5.6)]. Compared to subcutaneous administration, the intravenous route of administration may lessen the risk for development of antibodies to Mircera.
In 1789 patients treated with Mircera in clinical studies, antibody testing using an enzyme-linked immunosorbent assay (ELISA) was conducted at baseline and during treatment. Antibody development was not detected in any of the patients. ELISA testing was conducted in 104 pediatric patients. In the first study (NCT00717366), blood samples to measure anti-Mircera and anti-EPO antibodies were collected on Week 1, Week 13, Week 21 and Week 73. In the second study (NCT03552393), they were measured at Week 1, Week 9, Week 21, and Week 45. No patients tested positive at any time during the first study. In the second study, two patients tested positive for anti-Mircera and anti-EPO antibodies. For one patient, the Week 1 samples before the first Mircera administration were already positive. The second patient had a transient positive test at Week 21. The transient presence of antibodies did not neutralize the response and was not associated with any adverse events.
Because of the low occurrence of anti-drug antibodies, the effect of these antibodies on the pharmacokinetics, pharmacodynamics, safety, and/or effectiveness of methoxy polyethylene glycol-epoetin beta products is unknown.
-
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
No carcinogenicity or genotoxicity studies have been conducted with Mircera. Methoxy polyethylene glycol-epoetin beta did not induce a proliferative response in either the erythropoietin receptor positive cell lines HepG2 and K562 or the erythropoietin receptor negative cell line RT112 in vitro. In addition, using a panel of human tissues, the in vitro binding of methoxy polyethylene glycol-epoetin beta was observed only in bone marrow progenitor cells.
When methoxy polyethylene glycol-epoetin beta was administered subcutaneously to male and female rats prior to and during mating, reproductive performance, fertility, and sperm assessment parameters were not affected.

14 CLINICAL STUDIES
14.1 Adult Patients
Patients with Chronic Kidney Disease on Dialysis: ESA Effects on Rates of Transfusion
In early clinical studies conducted in CKD patients on dialysis, ESAs have been shown to reduce the use of RBC transfusions. These studies enrolled patients with mean baseline hemoglobin levels of approximately 7.5 g/dL and ESAs were generally titrated to achieve a hemoglobin level of approximately 12 g/dL. Fewer transfusions were given during the ESA treatment period when compared to a pre-treatment interval.
In NHS, the yearly transfusion rate was 51.5% in the lower hemoglobin group (10 g/dL) and 32.4% in the higher hemoglobin group (14 g/dL).
Patients with Chronic Kidney Disease Not on Dialysis: ESA Effects on Rates of Transfusion
In TREAT, a randomized, double-blind trial of 4038 patients with CKD and type 2 diabetes not on dialysis, a post-hoc analysis showed that the proportion of patients receiving RBC transfusions was lower in patients administered an ESA to target a hemoglobin of 13 g/dL compared to the control arm in which the ESA was administered intermittently if hemoglobin concentration decreased to less than 9 g/dL (15% vs. 25%, respectively). In CHOIR, a randomized open-label study of 1432 patients with CKD not on dialysis, use of an ESA to target a higher (13.5 g/dL) vs. lower (11.3 g/dL) hemoglobin goal did not reduce the use of RBC transfusions. In each trial, no benefits occurred for the cardiovascular or end-stage renal disease outcomes. In each trial, the potential benefit of ESA therapy was offset by worse cardiovascular safety outcomes resulting in an unfavorable benefit-risk profile [see Warnings and Precautions (5.1)].
ESA Effects on Quality of Life
Mircera use has not been demonstrated in controlled clinical trials to improve quality of life, fatigue, or patient well-being.
ESA Effects on Rates of Death and Other Serious Cardiac Adverse Events
Three randomized outcome trials (NHS, CHOIR and TREAT) have been conducted in patients with CKD using Epogen/PROCRIT/Aranesp to target higher vs. lower hemoglobin levels. Though these trials were designed to establish a cardiovascular or renal benefit of targeting higher hemoglobin levels, in all 3 studies, patients randomized to the higher hemoglobin target experienced worse cardiovascular outcomes and showed no reduction in progression to ESRD. In each trial, the potential benefit of ESA therapy was offset by worse cardiovascular safety outcomes resulting in an unfavorable benefit-risk profile [see Warnings and Precautions (5.1)].
Other ESA Trials
The efficacy and safety of Mircera were assessed in six open-label, multi-center clinical studies that randomized patients to either Mircera or a comparator ESA. Two studies evaluated anemic patients with CKD who were not treated with an ESA at baseline and four studies evaluated patients who were receiving an ESA for treatment of the anemia of CKD. In all studies, patients were assessed as clinically stable at baseline and without evidence of infection or inflammation as determined by history and laboratory data, including C-reactive protein (CRP ≤ 15 mg/L for study 1 and CRP ≤ 30 mg/L for studies 2 to 6). A CRP value above the threshold led to the exclusion of no more than 3% of the screened patients.
In the clinical studies, ESAs were administered to achieve specific hemoglobin levels (see Table 7 and Table 8). Following stabilization of hemoglobin levels (12 g/dL), the median monthly Mircera dose was 150 mcg (range of 97 mcg to 270 mcg).
Patients Not Currently Treated with an ESA
In Study 1 patients who were not receiving dialysis were randomized to Mircera or darbepoetin alfa, administered for 28 weeks. The starting dose of Mircera was 0.6 mcg/kg administered subcutaneously once every two weeks and the starting dose of darbepoetin alfa was 0.45 mcg/kg administered subcutaneously once a week. In Study 2, patients who were receiving dialysis were randomized to Mircera or another ESA (epoetin alfa or epoetin beta), administered for 24 weeks. The starting dose of Mircera was 0.4 mcg/kg administered intravenously once every two weeks and the starting dose of the comparator was administered intravenously three times a week, consistent with the product’s recommended dose. In these studies, the observed median dose of Mircera once every two weeks over the course of the correction/evaluation period was 0.6 mcg/kg. Table 7 provides the results of the two studies.

In the CORDATUS trial (NCT00559273), a randomized controlled study in patients with CKD not on dialysis and not currently treated with an ESA, Mircera, administered once monthly, was compared to darbepoetin alfa administered every week or every two weeks. Both treatment groups achieved statistical significance for hemoglobin response rate comparing with a fixed response rate of 60% [Mircera: 94%, CI: (89%, 97%), p<0.0001; darbepoetin alfa: 94%, CI: (88%, 97%), p<0.0001]. The Mircera group also achieved non-inferiority to the darbepoetin alfa group on the mean change of the baseline-adjusted Hb based on the protocol-specified NI margin of -0.75 [Mircera: 1.62 g/dL; darbepoetin alfa: 1.66 g/dL; difference: -0.036 g/dL with a two-sided 95% CI: (-0.252, 0.180)].
Patients Currently Treated with an ESA
Four studies assessed the ability of Mircera to maintain hemoglobin levels among patients currently treated with other ESAs. Patients were randomized to receive Mircera administrations either once every two weeks or once every four weeks, or to continue their current ESA dose and schedule. The initial Mircera dose was determined based on the patient’s previous weekly ESA dose. As shown in Table 8, treatment with Mircera once every two weeks and once every four weeks maintained hemoglobin levels within the targeted hemoglobin range (10 to 13.5 g/dL).

14.2 Pediatric Patients Currently Treated with an ESA
An open-label, multiple dose, multicenter, dose-finding study (NCT00717366) was conducted to determine the dose of intravenous Mircera when converting from treatment with another ESA (epoetin alfa/beta or darbepoetin alfa). The study was conducted in 64 pediatric patients with CKD who were on hemodialysis and who had stable hemoglobin (Hb) levels while previously receiving another ESA. The mean age of the patients was 13 years (age range: 5 to 17 years); 39% were 5 to 11 years of age, and 61% were 12 to 17 years of age. The patient population was 53% male, 72% White, 3% Black, 11% Asian and 14% Other. Eligible patients were administered Mircera intravenously once every 4 weeks for 20 weeks. After the first administration of Mircera, dosage adjustments were permitted to maintain target Hb levels.
Efficacy was established based on the change in Hb concentration (g/dL) between the baseline and evaluation periods. Of the two conversion factors studied, the recommended conversion factor for Mircera [see Dosage and Administration (2.2)] was confirmed based on patients maintaining Hb within target levels. Among the 48 patients who received Mircera dosed using the recommended conversion factor, 9 patients withdrew due to renal transplant, 2 patients withdrew due to administrative reasons, 1 died, and 1 patient refused treatment. One of the 13 patients who withdrew from the study entered the evaluation period (weeks 17 to 21). For the 36 patients who entered the evaluation period and received the dose of Mircera calculated using the recommended conversion factor, the mean change in Hb concentration from baseline between the baseline and the evaluation period was -0.15 g/dL with 95% CI (-0.49, 0.2).
Supportive efficacy results in the group treated with Mircera using the recommended conversion factor demonstrated that 75% of patients maintained Hb values within ± 1 g/dL of baseline and 81% maintained Hb values within 10 to 12 g/dL during the evaluation period. Seventy-seven percent (77%) of patients had a dose adjustment (either a dose decrease, increase or both).
A second open-label, single-arm, multicenter study (NCT03552393) was performed to ascertain the optimal starting dose of Mircera administered subcutaneously for the maintenance treatment of anemia in 40 pediatric patients with CKD on dialysis, or not on dialysis when switching from stable subcutaneous (SC) treatment with epoetin alfa, epoetin beta or darbepoetin alfa. The mean age of patients was 10 years (age range: 4.8months to 17 years); 30 % were less than 5 years of age, 27.5% were 5 to 11 years of age, and 42.5% were 12 years of age or older. The patient population was 58% male, 75% White, 8% Black, and 10% Hispanic or Latino. The starting dose was based on the conversion factors obtained from the intravenous dose-finding study. Mircera was administered SC once every 4 weeks for 20 weeks. Similarly, in this study, efficacy was established based on the change in Hb concentration (g/dL) between the baseline and evaluation periods. The study confirmed that the conversion factors are appropriate. Among the 40 patients who received Mircera, 2 patients (5%) discontinued during the evaluation period. The reasons for discontinuation from the evaluation period were kidney transplant and use of prohibited medication. An additional 4 patients discontinued from the extension period due to kidney transplant. For the 38 patients who had Hb concentration data available during the evaluation period (Weeks 17-21), the mean change in Hb concentration between the baseline and the evaluation period was 0.48 g/dL with 95% CI (0.15, 0.82).
Supportive efficacy results demonstrated that 50% of patients maintained Hb values within ± 1 g/dL of baseline and 63% maintained Hb values within 10 to 12 g/dL during the evaluation period. Dose adjustments (either a dose decrease, increase or both) were reported in 85% of patients.
