Single Ascending Dose PK, Oral Bioavailability and Food Effect Study in Healthy Male Volunteers

A Phase 1, Randomized Trial to Evaluate the Pharmacokinetics and Safety of Single Ascending Doses of Indoximod HCl (F2) Tablets (Part 1) and to Compare the Oral Bioavailability of Indoximod Cl (F2) Tablets and Indoximod Free Base Capsule Formulations and the Effect of Food (Part 2) in Healthy Male Volunteers

This 2-part study will assess the effect of formulation and food on the pharmacokinetics of Indoximod in healthy volunteers. Part 1 is a randomized single ascending dose study of indoximod salt formulation to characterize the PK profile and determine the safety and tolerability of each dose in healthy male volunteers. Part 2 is an open-label, randomized, 3-period, 3-way crossover study. Participants will receive single doses of Indoximod base or salt formulation, in the fasted or fed state.
