Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1, open-label, drug-drug interaction (DDI) study of pemvidutide (ALT-801) under steady state conditions on concomitantly administered medications in healthy subjects. The study will evaluate the effect of pemvidutide on the pharmacokinetics (PK) of metformin, warfarin, atorvastatin, digoxin, and the combined oral contraceptive (COC) ethinylestradiol/levonorgestrel. The study will be conducted in 3 parts, as described below. Each part will have 2 periods in a fixed sequence, where the first period is without pemvidutide administration and the second is with pemvidutide at steady state.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Part 1 Metformin and Atorvastatin with and without Pemvidutide

In Period 1, subjects received metformin 500 mg BID on Days 1 and 2, single doses of metformin 500 mg and atorvastatin 40 mg on Day 3, and a single dose of pemvidutide 0.6 mg on Day 8.

In Period 2, subjects received single doses of pemvidutide1.2 mg on Day 15 and 1.8 mg on Days 22 and 29, metformin 500 mg BID on Days 34 and 35, and pemvidutide 1.8 mg on Day 36 immediately followed by oral metformin 500 mg and atorvastatin 40 mg.

In Period 2, subjects received single doses of pemvidutide 1.2 mg on Day 22 and 1.8 mg on Days 29 and 36. Subjects also received COC once daily on Days 35 through 42 and a single dose of pemvidutide 1.8 mg followed immediately by a single dose of COC on Day 43.
