Titrate and adjust the maintenance dosage of MYCAPSSA based on IGF-1 levels, patient's signs and symptoms and tolerability [see Dosage and Administration (2.2, 2.3), Use in Specific Populations (8.6)].
2.5 Dosage Modifications with Concomitant Use of Proton Pump Inhibitors, H2-receptor Antagonists, or Antacids
Patients taking proton pump inhibitors, H2-receptor antagonists, or antacids concomitantly with MYCAPSSA may require increased dosages of MYCAPSSA [see Drug Interactions (7.1)].
- 3 DOSAGE FORMS AND STRENGTHS
Hypersensitivity to octreotide or any of the components of MYCAPSSA. Anaphylactoid reactions, including anaphylactic shock, have been reported in patients receiving octreotide [see Adverse Reactions (6.3)].
5 WARNINGS AND PRECAUTIONS
5.1 Cholelithiasis and Complications of Cholelithiasis
MYCAPSSA may inhibit gallbladder contractility and decrease bile secretion, which may lead to gallbladder abnormalities or sludge. Gallbladder-related adverse reactions have been reported in clinical trials in patients receiving MYCAPSSA. There have been postmarketing reports of cholelithiasis (gallstones) in patients taking somatostatin analogs resulting in complications, including cholecystitis, cholangitis, pancreatitis and requiring cholecystectomy [see Adverse Reactions (6)]. Monitor patients periodically. If complications of cholelithiasis are suspected, discontinue MYCAPSSA and treat appropriately.
5.2 Hyperglycemia and Hypoglycemia
MYCAPSSA alters the balance between the counter-regulatory hormones, insulin, glucagon, and growth hormone, which may result in hypoglycemia, or hyperglycemia, or diabetes mellitus. In clinical trials with MYCAPSSA, the following adverse reactions were reported: increased blood glucose (7%), hypoglycemia (4%), and diabetes mellitus (1%) [see Adverse Reactions (6.1)]. Blood glucose levels should be monitored when MYCAPSSA treatment is initiated, or when the dose is altered. Adjust antidiabetic treatment accordingly.
5.3 Thyroid Function Abnormalities
MYCAPSSA suppresses the secretion of thyroid-stimulating hormone, which may result in hypothyroidism. In clinical trials with MYCAPSSA, the following adverse reactions were reported: hypothyroidism (1%), increased TSH (1%), or decreased free T4 (1%) [see Adverse Reactions (6.1)]. Assess thyroid function periodically during treatment with MYCAPSSA.
5.4 Cardiac Function Abnormalities
Cardiac conduction abnormalities and other ECG changes including QT prolongation, axis shifts, early repolarization, low voltage, R/S transition, and early R wave progression, have occurred during treatment with octreotide. In MYCAPSSA clinical trials the following adverse reactions were reported: bradycardia (2%), conduction abnormalities (1%), and arrhythmias/tachycardia (2%) [see Adverse Reactions (6)]. These ECG changes may occur in patients with acromegaly. Dosage adjustments of concomitantly used drugs that have bradycardia effects (i.e. beta-blockers) may be necessary [see Drug Interactions (7.2)].
5.5 Decreased Vitamin B12 Levels and Abnormal Schilling's Tests
MYCAPSSA may alter absorption of dietary fats in some patients. Decreased vitamin B12 levels and abnormal Schilling's tests have been observed in some patients receiving octreotide. Monitor vitamin B12 levels during treatment with MYCAPSSA.
6 ADVERSE REACTIONS
The following important adverse reactions are described below and elsewhere in the labeling:
- Cholelithiasis and Complications of Cholelithiasis [see Warnings and Precautions (5.1)]
- Hyperglycemia and Hypoglycemia [see Warnings and Precautions (5.2)]
- Thyroid Function Abnormalities [see Warnings and Precautions (5.3)]
- Cardiac Function Abnormalities [see Warnings and Precautions (5.4)]
- Decreased Vitamin B12 Levels and Abnormal Schilling's Tests [see Warnings and Precautions (5.5)]
6.1 Clinical Studies Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
MYCAPSSA has been evaluated in patients with acromegaly in a placebo-controlled study [see Clinical Studies (14)] and an open-label baseline-controlled study. The data reflect exposure of 183 patients to MYCAPSSA for a mean duration of 29 weeks. In the overall study population, 56% were female and the average age of patients was 54.3 years. Adverse reactions occurring ≥ 5% and greater than placebo for the placebo-controlled study are presented in Table 1 and adverse reactions occurring ≥ 5% in the open-label study are presented in Table 2.

Other Adverse Reactions
In the placebo-controlled study, in patients treated with MYCAPSSA, acute cholecystitis occurred in 4% of patients.
In the open-label study, cholelithiasis occurred in 4.5% of patients and bile duct obstruction, bile duct stone, acute cholecystitis and jaundice occurred in 1% of patients each.
In the placebo-controlled study, 18% of patients treated with MYCAPSSA and 4% of patients treated with placebo developed at least one glucose value above the upper normal limit. All patients with abnormal glucose values were asymptomatic. Asymptomatic hypoglycemia was reported in 4% of patients.
In the open-label study 16% of patients developed a glucose value above the upper limit of normal. Asymptomatic hypoglycemia was reported in 4% and symptomatic hypoglycemia was reported in 1% of patients. Diabetes was reported in 1% of patients.
In the open-label study, hypothyroidism, increased TSH, or decreased free T4 were reported in 1% of patients.
In the open-label study, bradycardia was reported in 2%, conduction abnormalities in 1%, and arrhythmias/tachycardia in 2% of patients.
Gastrointestinal symptoms were the most commonly reported adverse reactions with MYCAPSSA.
In the placebo-controlled study, gastrointestinal adverse reactions were reported in 68% of patients treated with MYCAPSSA. These adverse reactions were diarrhea, nausea, vomiting, abdominal discomfort, dyspepsia, large intestinal polyp, abdominal pain, constipation, and flatulence. The adverse reactions were mild to moderate, occurred mostly during the initial 3 months of treatment, and resolved on treatment within a median duration of 8 days.
In the open-label study, gastrointestinal adverse reactions were reported in 57% of patients. Gastrointestinal adverse reactions occurring in ≥ 1% of patients were nausea, diarrhea, dyspepsia, abdominal pain, abdominal distention, vomiting, flatulence, constipation, gastroesophageal reflux disease, abdominal discomfort, frequent bowel movement, gastritis, hemorrhoids, dry mouth, and gastrointestinal motility disorder. Large intestinal polyp was reported in 1 patient. The adverse reactions were mostly mild to moderate, occurred during the initial 2 months of treatment, and resolved on treatment within a median of 13 days. Ten patients discontinued treatment due to gastrointestinal adverse reactions.
As with all therapeutic peptides, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other octreotide acetate products may be misleading.
No antibodies to the octreotide peptide from MYCAPSSA were detected in 149 patients assessed in the open label study throughout 13 months of treatment.
6.3 Postmarketing Experience
The following adverse reactions have been identified during the post-approval use of octreotide acetate. 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.
- Blood and lymphatic: pancytopenia, thrombocytopenia
- Cardiac: myocardial infarction, cardiac arrest, atrial fibrillation
- Ear and labyrinth: deafness
- Endocrine: diabetes insipidus, adrenal insufficiency in patients 18 months of age and under, pituitary apoplexy
- Eye: glaucoma, visual field defect, scotoma, retinal vein thrombosis
- Gastrointestinal: intestinal obstruction, peptic/gastric ulcer, abdomen enlarged
- General and administration site: generalized edema, facial edema
- Hepatobiliary: gallbladder polyp, fatty liver, hepatitis
- Immune: anaphylactoid reactions including anaphylactic shock

- Reproductive and breast: gynecomastia, galactorrhea, libido decrease, breast carcinoma
- Respiratory: status asthmaticus, pulmonary hypertension, pulmonary nodule, pneumothorax aggravated
- Skin and subcutaneous tissue: urticaria, cellulitis, petechiae
- Vascular: orthostatic hypotension, hematuria, gastrointestinal hemorrhage, arterial thrombosis of the arm
7 DRUG INTERACTIONS
7.1 Effects of Other Drugs on MYCAPSSA
Proton Pump Inhibitors, H2-receptor Antagonists, or Antacids Clinical Impact: Concomitant administration of MYCAPSSA with esomeprazole resulted in a decrease in the bioavailability for MYCAPSSA [See Clinical Pharmacology (12.3)]. Drugs that alter the pH of the upper GI tract (e.g., other proton pump inhibitors (PPIs), H2-receptor antagonists, and antacids) may alter the absorption of MYCAPSSA and lead to a reduction in bioavailability. Intervention: Co-administration of MYCAPSSA with PPIs, H2-blockers, or antacids may require increased doses of MYCAPSSA.
7.2 Effects of MYCAPSSA on Other Drugs
Cyclosporine Clinical Impact: Concomitant administration of MYCAPSSA with cyclosporine resulted in a decrease in cyclosporine bioavailability [see Clinical Pharmacology (12.3)]. Intervention: Adjustment of cyclosporine dose to maintain therapeutic levels may be necessitated. Insulin and Antidiabetic Drugs Clinical Impact: MYCAPSSA inhibits the secretion of insulin and glucagon. Intervention: Monitor blood glucose levels in diabetic patients upon MYCAPSSA initiation and subsequent dose adjustment. Patients receiving insulin or antidiabetic drugs agents may require dose adjustment of these therapeutic agents. Digoxin Clinical Impact: Concomitant administration of MYCAPSSA with digoxin resulted in a decrease in digoxin peak exposure [see Clinical Pharmacology (12.3)]. Intervention: Digoxin has a narrow therapeutic ratio and careful assessment of clinical response should be performed when digoxin is concomitantly administered with MYCAPSSA. Lisinopril Clinical Impact: Concomitant administration of MYCAPSSA increases lisinopril bioavailability [see Clinical Pharmacology (12.3)]. Intervention: Monitor patient's blood pressure and adjust the dosage of lisinopril if needed. Levonorgestrel Clinical Impact: Concomitant administration of MYCAPSSA with levonorgestrel decreases levonorgestrel bioavailability [see Clinical Pharmacology (12.3)]. Intervention: Decreased bioavailability may potentially diminish the effectiveness of combined oral contraceptives (COCs) or increase breakthrough bleeding. Counsel women to use an alternative non-hormonal method of contraception or a back-up method when MYCAPSSA is used with COCs. Bromocriptine Clinical Impact: Concomitant administration of MYCAPSSA with bromocriptine may increase the systemic exposure of bromocriptine [see Clinical Pharmacology (12.3)]. Intervention: Dose adjustment of bromocriptine may be necessary. Beta Blocker and Calcium Channel Blockers Clinical Impact: MYCAPSSA may cause bradycardia in acromegaly patients. Intervention: Patients receiving beta blockers or calcium channel blockers may require dose adjustments of these therapeutic agents. Drugs Metabolized by CYP 450 Enzymes Clinical Impact: Limited published data indicate that somatostatin analogs including MYCAPSSA may decrease the metabolic clearance of compounds known to be metabolized by cytochrome P450 enzymes, which may be due to the suppression of GH. Intervention: Concomitant use with other drugs mainly metabolized by CYP3A4 that have a narrow therapeutic index (e.g., quinidine) should be used with caution and increased monitoring may be required.
8 USE IN SPECIFIC POPULATIONS
Available data from case reports with octreotide acetate use in pregnant women are insufficient to identify a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with MYCAPSSA. No adverse developmental effects were observed with intravenous administration of octreotide to pregnant rats and rabbits during organogenesis at doses 7 and 13 times, respectively, the clinical dose based on octreotide injection body surface area. Transient growth retardation, with no impact on postnatal development, was observed in rat offspring from a pre- and post-natal study of octreotide at intravenous doses below the clinical dose based on octreotide injection body surface area (see Data).
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%-4% and 15%-20%, respectively.
In embryo-fetal development studies in rats and rabbits, pregnant animals received intravenous doses of octreotide up to 1 mg/kg/day during the period of organogenesis. A slight reduction in body weight gain was noted in pregnant rats at 0.1 and 1 mg/kg/day. There were no maternal effects in rabbits or embryo-fetal effects in either species up to the maximum dose tested. At 1 mg/kg/day in rats and rabbits, the dose multiple was approximately 7 and 13 times, respectively, the clinical dose based on octreotide injection body surface area.
In a pre- and post-natal development rat study at intravenous doses of 0.02-1 mg/kg/day, a transient growth retardation of the offspring was observed at all doses which was possibly a consequence of growth hormone inhibition by octreotide. The doses attributed to the delayed growth are below the clinical dose based on octreotide injection body surface area.
There is no information available on the presence of octreotide in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. Studies show that octreotide administered subcutaneously passes into the milk of lactating rats (see Data). When a drug is present in animal milk, it is likely that the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for MYCAPSSA and any potential adverse effects on the breastfed child from MYCAPSSA or from the underlying maternal condition.
8.3 Females and Males of Reproductive Potential
Discuss the potential for unintended pregnancy with premenopausal women as the therapeutic benefits of a reduction in GH levels and normalization of IGF-1 concentration in acromegalic females treated with octreotide may lead to improved fertility.
8.4 Pediatric Use
Safety and efficacy of MYCAPSSA in pediatric patients have not been established.
In post-marketing reports, serious adverse reactions, including hypoxia, necrotizing enterocolitis, and death, have been reported with octreotide injection use in pediatric patients, most notably in children under 2 years of age.
8.5 Geriatric Use
Clinical studies of octreotide did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In MYCAPSSA clinical studies, 39 patients (21%) were age 65 years or over and 1 patient was age 75 years or over. No overall differences in safety or effectiveness were observed between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
8.6 Renal Impairment
In patients with mild, moderate, or severe renal impairment there is no dose adjustment recommended for MYCAPSSA. There is a significant increase in octreotide exposure in patients with end stage renal disease (ESRD). Start patients with ESRD on MYCAPSSA 20 mg orally daily. Adjust the maintenance dose thereafter based on IGF-1 levels, patient's signs and symptoms, and tolerability [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].
8.7 Hepatic Impairment
Patients with liver cirrhosis and patients with fatty liver disease showed prolonged elimination of octreotide following subcutaneous administration of drug [see Clinical Pharmacology (12.3)].
A limited number of accidental overdoses of injectable octreotide acetate in adults has been reported. The doses ranged from 2.4 mg/day to 6 mg/day administered by continuous infusion or subcutaneously 1.5 mg three times a day. Adverse reactions in some patients included arrhythmia, hypotension, cardiac arrest, brain hypoxia, pancreatitis, hepatic steatosis, hepatomegaly, lactic acidosis, flushing, diarrhea, lethargy, weakness, and weight loss.
If overdose occurs, contact Poison Control (1-800-222-1222) for latest recommendations.
MYCAPSSA delayed release capsules contain octreotide acetate, a somatostatin analog. Octreotide is known chemically as L-cysteinamide, D-phenylalanyl-L-cysteinyl-L-phenylalanyl-D-tryptophyl-L-lysyl-L-threonyl-N-[2-hydroxy-1-(hydroxy-methyl) propyl]-, cyclic (2→7)-disulfide; [R-(R*,R*)].
The molecular weight of octreotide is 1019.3 (free peptide, C49H66N10O10S2) and its amino acid sequence is:
MYCAPSSA (octreotide) delayed-release capsules are enteric-coated capsules for oral use. Each capsule contains 20 mg of octreotide (provided as octreotide acetate). Octreotide is present as a salt with 1.4 to 2.5 molar equivalents of acetate. The capsules contain the following inactive ingredients: polyvinylpyrrolidone (PVP-12), sodium caprylate, magnesium chloride, polysorbate 80, glyceryl monocaprylate, glyceryl tricaprylate, gelatin, gelatin capsules, and Acryl-EZE® (methacrylate). The capsule is printed with "OT 20" in Opacode® black ink.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Octreotide exerts pharmacologic actions similar to the natural hormone somatostatin, but is a more potent inhibitor of GH, glucagon, and insulin than somatostatin. Like somatostatin, it also suppresses luteinizing hormone (LH) response to gonadotropin-releasing hormone (GnRH), decreases splanchnic blood flow, and inhibits release of serotonin, gastrin, vasoactive intestinal peptide, secretin, motilin, and pancreatic polypeptide.
In a single-dose PK study conducted in healthy volunteers, inhibition of GH (as measured by Cavg) was observed in all subjects receiving MYCAPSSA, as compared to their GH levels prior to MYCAPSSA.
In a study designed to assess the duration of MYCAPSSA-induced increased intestinal permeability, an increase in paracellular permeability was observed 2 hours after MYCAPSSA administration and returned to baseline by 5.5 hours after MYCAPSSA administration. MYCAPSSA-induced permeability is completely reversible within this timeframe.
MYCAPSSA maintained GH and IGF-1 levels in patients with acromegaly.
Single doses of octreotide acetate given subcutaneously have been shown to inhibit gallbladder contractility and to decrease bile secretion in normal volunteers. In clinical trials the incidence of gallstone or biliary sludge formation was markedly increased [see Warnings and Precautions (5.1)].
Octreotide acetate may cause clinically significant suppression of TSH [see Warnings and Precautions (5.3)].
In healthy subjects, similar systemic exposure (AUC) was observed between a single dose oral administration of MYCAPSSA (20 mg octreotide acetate), and a single dose of subcutaneous Sandostatin IR (0.1 mg octreotide acetate). Peak octreotide levels (Cmax) were 33% lower following oral administration compared to the subcutaneous route. Absorption time was longer following oral administration compared to the subcutaneous route; peak concentrations were reached at a median of 1.67–2.5 hours after 20 mg MYCAPSSA administration compared to 0.5 hours for the subcutaneous administration.
In healthy subjects, after single-dose oral administration of MYCAPSSA, the systemic exposure of octreotide (Cmax, AUC0-24, and AUC0-inf) increased dose-proportionally at doses ranging from 3–40 mg.
In patients with acromegaly, there was a dose-related increase in the mean plasma octreotide concentrations after chronic administration of MYCAPSSA 40 mg (20 mg bid), 60 mg (40 mg AM / 20 mg PM), and 80 mg (40 mg AM / 40 mg PM) bid. Mean peak concentrations (Cmax) following chronic dosing were lower in patients with acromegaly (mean [CV%] = 2.51 ng/mL [80%] and 5.30 ng/mL [76%] at 20 and 40 mg bid, respectively) compared to single-dose peak concentrations observed in healthy subjects at the same dose (mean [CV%] = 3.62 [53%] and 8.21 ng/mL [88%] at 20 and 40 mg, respectively).
In healthy volunteers, the distribution half-life (tα½) of octreotide acetate from plasma after subcutaneous administration was 0.2 h, the volume of distribution (Vdss) was estimated to be 13.6 L, and the total body clearance ranged from 7–10 L/hr. In blood, the distribution into the erythrocytes was found to be negligible and about 65% was bound in the plasma in a concentration-independent manner. Binding was mainly to lipoprotein and, to a lesser extent, to albumin.
In patients with acromegaly, the Vdss following subcutaneous administration was increased compared to healthy volunteers, estimated to be 21.6 L; mean peak concentrations were lower in acromegaly patients compared to healthy volunteers (2.8 ng/mL vs 5.2 ng/mL, respectively after 0.1 ng/mL dose).
According to data obtained with the immediate-release octreotide subcutaneous injection, approximately 32% of the dose is excreted unchanged in the urine.
In healthy subjects, there was no effect of route of administration on octreotide elimination, and comparable mean elimination half-lives (t½) of 2.3 hours and 2.7 hours were demonstrated between subcutaneous injection and oral octreotide treatments, respectively.
In patients with acromegaly, elimination after chronic dosing was slightly slower than that seen in healthy volunteers, with mean apparent half-life values at steady state ranging from 3.2–4.5 hours across doses (20 mg, 40 mg, 60 mg, and 80 mg). Elimination is complete approximately 48 hours after the last dose in patients who have achieved steady-state plasma levels. Minimal accumulation (approximately 10%) was observed in patients after repeat administration of MYCAPSSA.
In patients 65 years of age and older, after subcutaneous administration of octreotide acetate, the half-life of octreotide increased significantly (46%) and clearance of octreotide decreased significantly (26%).
Patients with Renal Impairment
Exposure in patients with severe renal impairment was not substantially different from that of the matched controls. Following oral administration of a single dose of 20 mg MYCAPSSA to patients with severe renal impairment (eGFR 15–29 mL/min/1.73m2) and patients with end-stage renal disease (ESRD) requiring dialysis, patients with ESRD on dialysis had a 46% decrease in clearance with a corresponding 87% increase in AUC and 85% increase in t½ compared to matched healthy subjects. ESRD patients had higher mean plasma concentrations than did those with severe renal impairment with higher mean values for Cmax (9.30 ng/mL compared to 6.13 ng/mL in the matched controls), AUC0–t (68.0 h∙ng/mL compared to 32.2 h∙ng/mL in the matched controls), AUCinf (69.5 h∙ng/mL compared to 32.4 h∙ng/mL in the matched controls), and t½ (7.09 hr compared to 3.84 hr in the matched controls), consistent with the known effect of renal impairment on octreotide exposure [see Use in Specific Populations (8.6)].
Patients with Hepatic Impairment
In patients with liver cirrhosis, after subcutaneous administration of octreotide acetate, prolonged elimination of drug was observed, with octreotide acetate t½ increasing from 1.9–3.7 hr and total body clearance decreasing from 7–10 L/hr to 5.9 L/hr, whereas patients with fatty liver disease showed t½ increased to 3.4 hr and total body clearance of 8.2 L/hr.
Limited published data indicate that somatostatin analogs including MYCAPSSA may decrease the metabolic clearance of compounds known to be metabolized by cytochrome P450 enzymes, which may be due to the suppression of GH [see Drug Interactions (7.2)].
Octreotide has been associated with alterations in nutrient absorption, so it may have an effect on absorption of orally administered drugs.

13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Studies in laboratory animals have demonstrated no mutagenic potential of octreotide acetate.
No carcinogenicity studies have been conducted with MYCAPSSA. No carcinogenic potential was demonstrated in mice treated subcutaneously with octreotide acetate for 85–99 weeks at doses up to 2000 mcg/kg/day (8 times the clinical dose based on octreotide injection body surface area). In a 116-week subcutaneous study in rats administered octreotide acetate, a 27% and 12% incidence of injection-site sarcomas or squamous cell carcinomas was observed in males and females, respectively, at the highest dose level of 1250 mcg/kg/day (10 times the clinical dose based on octreotide injection body surface area) compared to an incidence of 8% to 10% in the vehicle-control groups. The increased incidence of injection-site tumors was most probably caused by irritation and the high sensitivity of the rat to repeated subcutaneous injections at the same site. There was also a 15% incidence of uterine adenocarcinomas in the 1250 mcg/kg/day females compared to 7% in the saline-control females and 0% in the vehicle-control females. The presence of endometritis coupled with the absence of corpora lutea, the reduction in mammary fibroadenomas, and the presence of uterine dilatation suggest that the uterine tumors were associated with estrogen dominance in the aged female rats, which does not occur in humans.
No fertility studies in animals have been conducted with MYCAPSSA. Injectable octreotide acetate did not impair fertility in rats at doses up to 1000 mcg/kg/day, which represents 7 times the clinical dose based on octreotide injection body surface area.
14 CLINICAL STUDIES
The efficacy of MYCAPSSA was established in a 9 month, randomized, double-blind, placebo-controlled study (NCT03252353) that enrolled 56 patients with acromegaly.
In the overall study population, 54% were female and the average age of patients was 55 years. 91% of patients were Caucasian, 5% Asian, 2% Black, and 2% Other. The percentage of patients with previous pituitary surgery was 88%. The baseline IGF-1 levels (the average of 2 assessments measured within 2 weeks of randomization) was 0.80 times ULN (range: 0.5–1.1 times ULN) in the patients treated with MYCAPSSA and 0.84 times ULN (range: 0.3–1.1 times ULN) in patients treated with the placebo.
In this study, patients initiated MYCAPSSA treatment twice daily 1 month after their last injection of somatostatin analogs. The starting dose was 40 mg (20 mg in the morning and 20 mg in the evening). Dose increase was allowed during dose titration to 60 mg (40 mg in the morning and 20 mg in the evening) and to a maximal dose of 80 mg daily (40 mg in the morning and 40 mg in the evening) until patients were deemed adequately controlled based on biochemical results and/or clinical judgement. Patients then maintained their target dose until end of treatment.
The primary efficacy endpoint was somatostatin dose-adjusted proportion of patients who maintain their biochemical response, defined as an IGF-1 levels less than or equal to the ULN at the end of 9 months of treatment. 58% of patients treated with MYCAPSSA vs. 19% of patients treated with placebo maintained their biochemical response.
25% of patients treated with MYCAPSSA required discontinuation of MYCAPSSA and treatment with other somatostatin analogs at some point during the 9-month study. Criteria for somatostatin analog rescue were IGF-1 levels higher than 1.3 times ULN and exacerbation of acromegaly signs and symptoms on two consecutive assessments while treated for at least 2 weeks with 80 mg/day or other reasons such as adverse reactions or patient's decision.
