BioNTech cancer vaccine trial PFS miss ‘not surprising,’ says Evercore ISI
BioNTech's BNT113 vaccine missed a primary endpoint in a cancer trial, disappointing investors. Evercore ISI noted the result was consistent with earlier data and unlikely to show significant benefit. The firm maintains an Outperform rating and $130 price target for BioNTech, tying its shares more to other developments like pumitamig and Summit Therapeutics' H-3 readout.
