Goldman Sachs analyst Salveen Richter double upgraded Intercept Pharmaceuticals (ICPT) to Buy from Sell and raised his price target for the shares to $157 from $46. The stock closed Friday down 3.5%, or $3.57, to $97.26. The analyst says Ocaliva in fatty liver disease nonalcoholic steatohepatitis is the crux of Intercept's value proposition and that he's positive into the Phase 3 Regenerate interim readout in the first half of 2019. Richter this morning also downgraded Madrigal Pharmaceuticals (MDGL) to Neutral from Buy. He believes, however, that Madrigal's MGL-3196 is a "best-in-industry, next-generation" drug for nonalcoholic steatohepatitis. The analyst expects Intercept's Ocaliva will achieve one or both of the Phase 3 co-primary endpoints of NASH resolution and fibrosis improvement. He sees share upside of 60%-plus as the first half of 2019 catalyst approaches. Intercept should benefit from Ocaliva's global first-mover advantage in NASH, Richter tells investors in a research note. Goldman estimates peak global sales of NASH drugs to be $3.7B.
