ACTIVE MOIETY
ASP9831 is a phosphodiesterase-4 inhibitor developed to treat nonalcoholic steatohepatitis (NASH) it showed potent anti-inflammatory and antifibrotic effects in preclinical studies. We evaluated the efficacy and safety of ASP9831 in patients with NASH. Despite a relevant mechanism of action, ASP9831 did not significantly alter the biochemical markers of NASH, compared with placebo, in a clinical trial. This highlights the difficulties of developing therapeutics for NASH and the need for more extensive preclinical testing of mechanisms of potential drug candidates. Clinicaltrialsregister.eu: 2005-001687-31; EudraCT numbers: 2007-002114-19.
ACTIVE MOIETY
Originator: Astellas Pharma; Mechanism of Action: Type 4 cyclic nucleotide phosphodiesterase inhibitor; Highest Development Phase: Discontinued for Non-alcoholic steatohepatitis
