Madrigal’s Resmetirom Hits Phase 3 NASH Endpoints
Madrigal Pharmaceuticals says its resmetirom, a liver-directed selective thyroid hormone receptor agonist, met both liver histological improvement endpoints that FDA proposed as reasonably likely to predict clinical benefit to support accelerated approval for treating nonalcoholic steatohepatitis (NASH) with liver fibrosis. A company statement reported results from the pivotal Phase 3 MAESTRO-NASH registrational trial.
The statement says the drug was safe and well-tolerated at both 80 mg and 100 mg doses. It says the frequency of serious adverse events was similar across treatment arms for the 80 mg, 100 mg, and placebo groups, respectively. The most common adverse events reported with greater frequency in the resmetirom groups versus placebo were an excess of mild and transient diarrheas at the beginning of therapy and generally mild nausea.
