BioNTech Provides Update on Phase 2/3 Clinical Trial for mRNA Cancer Immunotherapy Candidate BNT113 in Metastatic HPV16-positive Head and Neck Cancer 

$BNTXPress releaseOct 13, 2026, 6:45 AM ETRead the release

BioNTech's AHEAD-MERIT Phase 2/3 trial of BNT113 plus pembrolizumab missed its first dual primary endpoint of progression-free survival versus pembrolizumab alone in first-line metastatic HPV16+ head and neck cancer. The IDMC recommended the trial continue to the second dual primary endpoint of overall survival; under the pre-specified design, a statistically significant OS improvement would still constitute a positive trial outcome despite the PFS miss.
