Frequently asked questions about BNT113

What is BNT113 used for?

BNT113 is being developed for HPV-related cancers, specifically unresectable head and neck squamous cell carcinoma that is positive for human papillomavirus 16 and expresses the PD-L1 protein. It is also being studied in other HPV-related carcinomas, including cervical, penile, and unknown primary tumors.

Who is developing BNT113?

BNT113 is being developed by BioNTech SE, a German biotechnology company that trades on the Nasdaq under the ticker BNTX. BioNTech is running the clinical program for BNT113 in HPV-positive head and neck cancer and other HPV-related malignancies.

What phase is BNT113 in?

BNT113 is in clinical development. It has been studied in a completed Phase 1 trial and is currently being evaluated in an active Phase 2 trial. BNT113 is investigational and has not been approved by the FDA for any indication.

What clinical trials is BNT113 in?

BNT113 has been evaluated in two clinical trials. The Phase 2 trial NCT04534205 is testing BNT113 in combination with pembrolizumab versus pembrolizumab alone in HPV16-positive, PD-L1-expressing head and neck cancer, and it is active but not recruiting. The completed Phase 1 trial NCT03418480 studied BNT113 in HPV-related carcinomas.

How many patients have been enrolled in BNT113 trials?

Across its clinical program, 358 patients are enrolled in the Phase 2 trial NCT04534205, which is testing BNT113 plus pembrolizumab against pembrolizumab alone. The completed Phase 1 trial NCT03418480 enrolled 32 patients with HPV-related carcinomas, including head and neck, cervical, and penile neoplasms.

Where is the BNT113 Phase 2 trial being conducted?

The Phase 2 trial NCT04534205 is running in the United States, Argentina, Australia, Austria, Belgium, Brazil, Canada, Chile, Czechia, France, Germany, Hungary, Israel, Italy, Mexico, Poland, Portugal, South Korea, Spain, Taiwan, and the United Kingdom. It enrolls adults 18 years and older with unresectable, metastatic, or recurrent head and neck cancer.
