Conditions

Postbariatric Hypoglycemia

Brief summary

This clinical study will evaluate whether taking an investigational drug called exendin 9-39 is safe, well-tolerated, and helps to prevent low blood sugar in people who have had bariatric surgery and later develop a rare condition called postbariatric hypoglycemia (PBH).

Detailed description

This is a Phase 2, multicenter, randomized, single-blind, placebo-controlled cross-over study in patients with refractory PBH. Participants will be randomized and assigned in a 1:1 ratio to one of two treatment arms. All participants will receive 2 dosing regimens of exendin 9-39 and matching placebo self-administered via subcutaneous (SC) injection. Participants will undergo in-clinic mixed meal tolerance test (MMTT) provocation with concomitant blood draws and symptom assessments.

Interventions

Exendin 9-39 is a competitive antagonist of GLP-1 at its receptor.

OTHERPlacebo

Placebo solution is identical to the active drug product except for the absence of the active ingredient, Exendin 9-39.

Outcome results

Postprandial Glucose Nadir

Plasma glucose nadir occurring within 3 hours of mixed-meal tolerance testing (MMTT)

Time frame: 3 hours following a liquid meal

Population: Analysis population are both treatment group 1 and treatment group 2. One participant was excluded from the efficacy analysis due to major protocol deviation.
