a dose escalating study of hc002 in healthy adult volunteers

Conditions: Inflammatory Disease; Autoimmune Diseases

Summary: this is a first-in-human (fih) study to evaluate the safety, tolerability, and pharmacokinetics (pk) of single and multiple ascending oral doses of hc002 in healthy adult participants.

this is a single center, randomized, double-blind, placebo-controlled, two-part study to evaluate the safety, tolerability, and pk of single (part 1) and multiple (part 2) oral doses of hc002. the study will enroll approximately 56 participants across 2 parts. in part 1 (sad), there will be 4 cohorts and in part 2 (mad), there will be 3 cohorts. in part 1, a single dose of hc002 or placebo will be administered on day 1. in part 2, multiple doses of hc002 or placebo will be administered once daily (qd) from day 1 to day 7.
