Safety, Tolerability, Pharmacokinetic and Pharmacodynamic Study of MBX 1416 in Healthy Subjects and Patients With Postbariatric Hypoglycemia
Study Details
Study Description
Brief Summary
The purpose of this trial is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple doses of MBX 1416 in healthy volunteers and patients with postbariatric hypoglycemia.
This study includes 2 parts. Part A involves a single dose of MBX 1416 or placebo taken as a subcutaneous injection (SC). Part B involves repeat doses of MBX 1416 or placebo taken as a subcutaneous injection (SC).
