This is a randomized, single-blind, placebo-controlled, once daily (QD) dose study of CRV431 in presumed NASH F2/F3 subjects.
This is a randomized, single-blind, placebo-controlled, once daily (QD) dose study of CRV431 in presumed NASH F2/F3 subjects. Study will evaluate the safety and tolerability of a once daily 75mg dose and 225mg of CRV431 compared to placebo over 28 days of dosing. Pharmacokinetic parameters of CRV431 and its major metabolites and fraction unbound will also be evaluated. Non-invasive antifibrotic bio-markers will be collected and quantified from presumed NASH F2/F3 subjects dosed with 75mg CRV431 or placebo.
