Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

MYCAPSSA™ (formerly Octreolin™) is a proprietary oral form of the approved injectable medical product octreotide used to treat acromegaly. This study will evaluate the efficacy and safety of MYCAPSSA™ treatment in patients with acromegaly.

Interventions

  • Octreotide capsulesDrug

Arms1

  • Experimental

    Octreotide capsules

    Participants received octreotide capsules orally twice a day for up to 13 months. Dosing started at 40 mg per day (20 in the morning + 20 in the evening) and increased to 60 mg per day (40 in the morning + 20 in the evening) or 80 mg per day (40 in the morning + 40 in the evening) if there was inadequate IGF-1 suppression.

Primary outcomes2

Outcomes the sponsor listed as primary.

  1. Percentage of Responders at the End of the Core Treatment Period

    Time frame · End of the core treatment period (up to 7 months)

    Registry description

    A responder was defined as a participant with a serum insulin-like growth factor-1 (IGF-1) concentration \< 1.3 times the upper limit of normal (adjusted for age and gender) and a growth hormone (GH) concentration \< 2.5 ng/mL. The growth hormone concentration was the mean of 5 fasted GH serum concentrations collected at 30 minute intervals for 2 hours, 2 to 4 hours post-octreotide dose. IGF-1 concentration was determined in serum samples taken at the same visits GH concentration was assessed.

  2. Percentage of Responders at the End of the Extension Treatment Period

    Time frame · End of the extension treatment period (up to 13 months)

    Registry description

    A responder was defined as a participant with a serum insulin-like growth factor-1 (IGF-1) concentration \< 1.3 times the upper limit of normal (adjusted for age and gender) and a growth hormone (GH) concentration \< 2.5 ng/mL. The growth hormone concentration was the mean of 5 fasted GH serum concentrations collected at 30 minute intervals for 2 hours, 2 to 4 hours post-octreotide dose. IGF-1 concentration was determined in serum samples taken at the same visits GH concentration was assessed.

    Registry description

    The severity (absent, mild, moderate, severe) of the 5 acromegaly symptoms headache, perspiration, asthenia, swelling of extremities, and joint pain was assessed at Baseline and at the end of the extension treatment period. The percentage of participants with improved or maintained (no change) acromegaly symptoms from Baseline at the end of the extension treatment period is reported.

  6. Percentage of Participants With ≥ 1, 2, or 3 Acromegaly Symptoms at Baseline and at the End of the Extension Treatment Period

    Time frame · Baseline and the end of the extension treatment period (up to 13 months)
