About this study
Official title: A Phase 3, Randomized, Double-blind, Placebo-controlled, Multicenter Study to Evaluate Efficacy and Safety of Octreotide Capsules in Patients Who Demonstrated Biochemical Control on Injectable Somatostatin Receptor Ligands (SRL) Treatment
Octreotide capsule is a novel, orally-administered formulation of the commercially-available injectable drug octreotide. In a recent phase 3 trial, oral octreotide capsules demonstrated maintenance of biochemical response up to 13 months in the majority of patients with acromegaly previously managed with somatostatin analog injections (reference below).
Read the detailed description
This is a double blind, randomized study that assesses the efficacy and safety of octreotide capsules vs. placebo. Eligible acromegaly patients, treated with injectable somatostatin analogs, who are biochemically controlled and have prior evidence of active disease, will be randomized to receive either octreotide capsules or placebo for up to 36 weeks. At the end of this double blind, placebo controlled period, eligible patients will receive octreotide capsules in an open-labeled extension for at least one year. Patients failing to respond (per protocol), to oral treatment, (either placebo or octreotide capsules), will be rescued with the standard of care and upon meeting the eligibility criteria could also enroll into the long term extension with octreotide capsules.
This study received agreement from the FDA, under a special protocol assessment.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Patients Who Maintain Their Biochemical Response at the End of the Double Blind Placebo Controlled (DPC) Period.
Maintenance of response was defined by using the average IGF-1 level of the last 2 available assessments in the DPC period. If the average IGF-1 is ≤ 1×ULN, a patient was classified as a responder (i.e., maintained their biochemical response). If the average IGF-1 is > 1×ULN, a patient was classified as a non-responder. Patients who discontinue study medication during the DPC period for any reason was classified as non-responders for the primary analysis, regardless of their IGF-1 values.
Measured: Week 36
Secondary outcomes (2)
Number of Patients Who Maintain Growth Hormone (GH) Response at the End of the Double Blind Placebo Controlled Period
Maintenance of GH response was defined as having mean Growth Hormone (5 measurements 30 minutes apart) < 2.5 ng/mL at the end of the double blind placebo controlled period, out of those who were responders on Somatostatin Receptor Ligands (SRLs) injections at Screening.
Measured: Week 36
Number of Patients Who Begin Rescue Treatment
Number of Patients who Began Rescue Treatment Prior to and Including Week 36
