Postbariatric Hypoglycemia | Drug: exendin 9-39 Other: Placebo | Phase 2 |
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.
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 18 participants |

Arm | Intervention/treatment |
---|---|
Experimental: Treatment Group 1
patients will receive two dose regimens of exendin 9-39 and one placebo
|
Drug: exendin 9-39
Exendin 9-39 is a competitive antagonist of GLP-1 at its receptor.
Other Name: Glucagon-like peptide-1 (GLP-1) antagonist Other: Placebo Placebo solution is identical to the active drug product except for the absence of the active ingredient, Exendin 9-39. |
Experimental: Treatment Group 2
patients will receive two dose regimens of exendin 9-39 and one placebo (in a different sequence than Treatment Group 1)
|
Drug: exendin 9-39
Exendin 9-39 is a competitive antagonist of GLP-1 at its receptor.
Other Name: Glucagon-like peptide-1 (GLP-1) antagonist Other: Placebo Placebo solution is identical to the active drug product except for the absence of the active ingredient, Exendin 9-39. |
- Postprandial Hypoglycemia [ Time Frame: 3 hours following a liquid meal ]Plasma glucose nadir occurring within 3 hours of MMTT
- Incidence of treatment-emergent adverse events [ Time Frame: 6 weeks ]An adverse event can be any unfavorable and unintended sign, symptom, or disease that occurs during the study treatment periods.
- Severity score of postprandial neuroglycopenic signs and symptoms calculated from patients' responses to the Edinburgh Hypoglycemia Symptom Scale. (EHSS). [ Time Frame: 3 hours following a liquid meal ]Neuroglycopenic symptoms evaluated by the EHSS include blurred vision, confusion, drowsiness, speech difficulty, incoordination, dizziness, and inability to concentrate. Patients will complete the EHSS approximately every 30 minutes during each MMTT.
- Postprandial hyperinsulinemia. [ Time Frame: 3 hours following a liquid meal ]Peak postprandial insulin concentration in response to MMTT
