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.

What is MYCAPSSA?
  • MYCAPSSA is an oral prescription medicine used in the long-term maintenance treatment of acromegaly in people for whom initial treatment with octreotide or lanreotide has been effective and tolerated.
  • It is not known if MYCAPSSA is safe and effective in children.
Do not take MYCAPSSA if you:
  • are allergic to octreotide acetate or any of the ingredients in MYCAPSSA. MYCAPSSA can cause a serious allergic reaction including anaphylactic shock. Stop taking MYCAPSSA right away and get emergency help if you have any of these symptoms:
  • swelling of your tongue, throat, lips, eyes or face
  • severe itching of the skin with rash or raised bumps
  • chest pain

  • rapid heart beat
See the end of this leaflet for a complete list of ingredients in MYCAPSSA.
Before you take MYCAPSSA, tell your healthcare provider about all of your medical conditions, including if you:
  • have liver cirrhosis or liver problems
  • have kidney problems
  • are pregnant or plan to become pregnant. It is not known if MYCAPSSA will harm your unborn baby. MYCAPSSA may increase your chance of becoming pregnant.
  • are breastfeeding or plan to breastfeed. It is not known if MYCAPSSA passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby if you take MYCAPSSA.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
MYCAPSSA may affect the way other medicines work, and other medicines may affect how MYCAPSSA works.
