BioNTech's mRNA cancer therapy misses first goal in head and neck trial

BioNTech's experimental mRNA cancer immunotherapy, BNT113, combined with Merck's Keytruda, failed to meet the primary goal of improving progression-free survival in a mid-to-late-stage trial for head and neck cancer. Shares fell nearly 6% in premarket trading. The trial will continue to assess overall survival. According to Citi analyst Geoffrey Meacham, the results were disappointing but not unexpected due to the disease's complexity.
