Phase 1
Completed
- Conditions
- NASH - Nonalcoholic Steatohepatitis
- Interventions
- Registration Number
- NCT04972396
- Lead Sponsor
- Altimmune, Inc.
- Brief Summary
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.
