BNT-113

BNT113 is an investigational mRNA cancer immunotherapy that induces anti-tumor immune responses against human papilloma virus type 16 positive (“HPV16+”) solid tumors, currently being evaluated in a pivotal clinical trial as a first-line treatment in patients with unresectable recurrent or metastatic HPV16+ head and neck squamous cell carcinoma (“HNSCC”) expressing PD-L1 HNSCC is the seventh most common cancer type worldwide, with about one third of cases being HPV-positive and of which the majority is driven by HPV161,2; there are currently no HPV-targeted treatments approved for patients with HPV16+ HNSCC3, leaving them with limited treatment options and poor prognosis With the Fast Track designation, the development of BNT113 can benefit from more frequent engagement with the U.S. Food and Drug Administration to support development and expedite regulatory review MAINZ, Germany, January 21, 2026 – BioNTech SE (Nasdaq: BNTX, “BioNTech” or “the Company”) today announced that the U.S. Food and Drug Administration (“FDA”) has granted Fast Track designation to BNT113, an investigational mRNA cancer immunotherapy, for the treatment of patients with human papillomavirus type 16 positive (“HPV16+”) head and neck squamous cell carcinoma (“HNSCC”) expressing PD-L1, a distinct cancer type associated by infection with high-risk human papillomavirus. The FDA Fast Track process is designed to facilitate the development and expedite the review of new drugs and vaccines that are intended to treat or prevent serious conditions and have the potential to address an unmet medical need. The designation has been granted based on preliminary safety and efficacy data from the ongoing pivotal Phase 2/3 AHEAD-MERIT clinical trial (NCT04534205) evaluating BNT113 in combination with pembrolizumab versus pembrolizumab monotherapy as a first-line treatment in patients with unresectable recurrent or metastatic HPV16+ HNSCC expressing PD-L1. HNSCC is the seventh most common cancer type worldwide with increasing global incidence, mainly driven by a rise in HPV16-related oropharyngeal tumors, the most common subtype of HNSCC.2,4 About one third of HNSCC cases are HPV-positive following a HPV infection, with a rising trend, of which about 90% of oropharyngeal cancers are driven by the subtype HPV16.1,5 Despite the distinct characteristics of HPV-positive tumors, there are currently no HPV-targeted treatments approved.3 Many patients with HPV16+ HNSCC experience disease progression under current standard of care treatments with a median overall survival of 20.7 months6, underlining the unmet medical need for novel HPV-targeted chemotherapy-free treatment options that improve long-term survival. HNSCC is among BioNTech's key tumor areas. BNT113 is an investigational mRNA cancer immunotherapy encoding the E6 and E7 proteins of HPV16, that are frequently found in HPV16+ solid tumors. This mRNA cancer immunotherapy approach is designed to induce HPV16-specific anti-tumor immune responses, thereby aiming to enhance clinical responses in patients being treated with checkpoint inhibitor standard of care treatment.
