Registry summary

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

Octreotide capsule is a novel, orally-administered formulation of the commercially-available injectable drug octreotide. In a recent phase 3 trial (OPTMAL; NCT03252353), oral octreotide capsules demonstrated sustained biochemical response up to 13 months in patients with acromegaly previously managed with somatostatin analog injections (ref). The objective of this study was to compare the efficacy, safety, and patient reported outcomes (PROs) between oral octreotide capsules and injectable somatostatin receptor ligands (SRLs).

Primary outcomes1

Outcomes the sponsor listed as primary.

  1. Proportion of Patients Who Are Biochemically Controlled Throughout the RCT Phase

    Time frame · 62 weeks

    Registry description

    Proportion of patients who are biochemically controlled throughout the RCT phase. A patient was considered biochemically controlled if IGF-1 Time Weighted Average (TWA) during the RCT phase is \<1.3 ULN

Secondary outcomes(6)
  1. Proportion of Patients With Clinical and Biochemical Control at the End of the RCT Phase

    Time frame · Week 62/ End of treatment; EOT

    Registry description

    Proportion of patients with clinical and biochemical control at the end of the RCT phase. Patients were considered biochemically and clinically controlled if they met both of the following criteria: * Their IGF-1 TWA during the RCT phase was \<1.3 times ULN * Their AIS score at week 62/EOT was maintained or reduced compared to week 26 (start of RCT phase)

  2. Proportion of Patients Who Maintain or Reduce the Overall Number of Active Acromegaly Symptoms at the End of the RCT Phase

    Time frame · 62 weeks

    Registry description

    Proportion of patients who maintain or reduce the overall number of active acromegaly symptoms at the end of the RCT phase (week 62/ EOT) , compared to week 26 (start of the RCT phase

  3. Proportion of Patients Who Maintain or Improve Their Overall Acromegaly Index of Severity (AIS) Score at the End of the RCT Phase

    Time frame · 62 weeks

    Registry description

    Proportion of patients who maintain or improve their overall Acromegaly index of severity (AIS) score at the end of the RCT phase (improvement defined as a reduction of at least one point in the AIS score), compared to week 26 (start of the RCT phase)

  4. Proportion of Patients of Those Completing the RCT Phase Who Entered the Study Extension Phase

    Time frame · 62 weeks

    Registry description

    Proportion of patients of those completing the RCT phase (at a time octreotide capsules were not commercially available at the specific country), who entered the Study Extension phase, overall and by treatment group

  5. Change in IGF-1 Levels in the RCT Phase

    Time frame · Change from Week 26 to week 62

    Registry description

    Change in IGF-1 levels from the start of the randomized phase to the end of RCT phase. Complete Responder (CR) is defined as IGF-1 ≤ 1 x ULN; Partial Responder (PR) is defined as 1 x ULN \< IGF-1 \< 1.3 x ULN, and Non-Responder (NR): IGF-1 ≥ 1.3 x ULN

  6. Change in GH Levels in the RCT Phase

    Time frame · Change from Week 26 to week 62

    Registry description

    Change in GH levels from the start of the randomized phase through the end of RCT phase.
