Frequently asked questions about BNT317

What is BNT317?

BNT317 is an investigational monoclonal antibody being developed by BioNTech SE for the treatment of advanced solid tumors. It is a Phase 1 oncology candidate and has not been approved for any indication. The program includes multiple dose levels and selected dose regimens, referred to as BNT317 DL1 through DL6 and selected DLA and DLB.

What is BNT317 used for in advanced solid tumors?

BNT317 is being studied as a treatment for advanced solid tumors. It is an investigational therapy in Phase 1 clinical development, so it is not yet approved for use in advanced solid tumors or any other condition. The ongoing trial is evaluating safety and preliminary effectiveness in adults with advanced solid tumors.

What does BNT317 target?

BNT317 targets PD-L1, a protein that is part of the PD-L1 pathway. By binding to PD-L1, the monoclonal antibody is designed to interfere with a mechanism that tumors use to suppress immune responses. This is the mechanism under investigation in the Phase 1 program.

Who is developing BNT317?

BNT317 is being developed by BioNTech SE, which trades under the ticker BNTX. BioNTech is the sponsor of the Phase 1 clinical trial evaluating BNT317 in advanced solid tumors. The company is responsible for the clinical development of the asset.

What phase is BNT317 in?

BNT317 is in Phase 1 clinical development. It is an investigational therapy and has not been approved by the FDA or any other regulatory agency. The single ongoing trial is a Phase 1 study, and no completed trials of BNT317 have been reported.

What clinical trials is BNT317 in?

BNT317 is being evaluated in one active clinical trial, NCT06750185, titled Safety and Preliminary Effectiveness of BNT317, an Investigational Therapy for Advanced Solid Tumors. The Phase 1 trial is currently recruiting and plans to enroll 248 participants across the United States and Australia.

Is BNT317 the same as BNT317 DL1 or BNT317 DL2?

Yes. BNT317 DL1, BNT317 DL2, BNT317 DL3, BNT317 DL4, BNT317 DL5, BNT317 DL6, BNT317 selected DLA, and BNT317 selected DLB are alternative names for BNT317. These labels refer to different dose levels and selected dose regimens within the same BioNTech development program for advanced solid tumors.
