Andrew Fein has given his Buy rating due to a combination of factors tied to the growing validation of TTR-depleter therapies and Prothena’s differentiated position within this space. He views the recent Royalty Pharma–Neurimmune transaction as external confirmation that depleter economics are attractive, with robust imaging and biomarker data suggesting a disease-modifying mechanism that existing stabilizers and silencers have yet to match.

In his view, Prothena’s partner Novo’s coramitug program exhibits meaningful clinical differentiation, including the only placebo-controlled Phase 2 dataset for a TTR depleter and strong NT-proBNP reductions on top of tafamidis background therapy. Combined with roughly $1.08B in remaining Novo milestones, tiered royalties on a multibillion-dollar market, and a modestly valued stock that he believes does not reflect this upside, Fein maintains a Buy rating with an unchanged $30 price target.
