Study Endpoints

Primary Endpoints

All parts - Number and percentage of participants with treatment emergent adverse events (TEAEs)
From the time of initiation of the first dose of BNT3214 until 90 days after the last dose of BNT3214

Per DL/cohort. By United States National Cancer Institute Common Terminology Criteria for Adverse Events grading, seriousness, and relatedness.

All parts - Number and percentage of participants with dose interruptions, reductions, and discontinuation of BNT3214 due to TEAEs
Up to 24 months

Per DL/cohort.

Parts A and B only - Number and percentage of participants with dose limiting toxicities (DLTs)
From first dose up to 28 days

During the DLT evaluation period

Part C only - Objective response rate (ORR)
Up to 30 months

Per DL/cohort. Defined as the percentage of participants in whom a confirmed complete response (CR) or partial response (PR) per RECIST v1.1 (based on the investigator's assessment) is observed as best overall response.

Secondary Endpoints

All parts - PK assessment: Area under the curve (AUC)
Up to 3 months from first dose of BNT3214
All parts - PK assessment: Maximum concentration (Cmax)
Up to 3 months from first dose of BNT3214
All parts - PK assessment: Time to maximum observed concentration (Tmax)
Up to 3 months from first dose of BNT3214

ArmTypeDescription
Part A - Escalating DLs of BNT3214EXPERIMENTALUp to 7 DLs of BNT3214. In Part A, participants will stay on the same DL. In DL1 and DL2, intra-participant dose escalation will be allowed at the discretion of the investigator as specified in the protocol.
Part B (optional) - Selected DLs of BNT3214EXPERIMENTALUp to 4 DLs. The starting dose for Part B will be at least one DL below the DL that has been declared safe for Part A.
Part C - Optimized DL of BNT3214EXPERIMENTALOptimized dose of BNT3214 selected based on totality of data from Parts A and (if conducted) Part B.
Part C - Dose expansion of BNT3214EXPERIMENTALDLs as recommended based on the totality of available data from previous parts.

Frequently asked questions about BNT3214

What is BNT3214 used for?

BNT3214 is an investigational small molecule being developed for the treatment of advanced solid tumor cancer. It is currently in Phase 1 clinical development, meaning it has not yet been approved by regulatory authorities and is still being studied for safety and preliminary efficacy in patients.

Who makes BNT3214?

BNT3214 is being developed by BioNTech SE, a biotechnology company traded on the NASDAQ under the ticker symbol BNTX. The company is conducting a Phase 1 clinical trial to evaluate the drug's safety and preliminary efficacy in adults with advanced solid tumors.

What phase is BNT3214 in?

BNT3214 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by the FDA or other regulatory agencies. The ongoing Phase 1 trial is recruiting participants to assess the safety and preliminary efficacy of BNT3214 in adults with advanced solid tumors.

What clinical trials is BNT3214 in?

BNT3214 is being studied in one active Phase 1 clinical trial with the identifier NCT07455734. This early-phase trial is assessing the safety and preliminary efficacy of BNT3214 in adults with advanced solid tumors. The trial is recruiting participants in Australia, China, South Korea, and Taiwan, with a planned enrollment of 533 patients.

Is BNT3214 a randomized controlled trial?

Yes, the Phase 1 clinical trial of BNT3214 is randomized and controlled, but it is not double-blinded. The trial, identified as NCT07455734, is designed to compare BNT3214 against a control, and it is actively recruiting patients with advanced solid tumor cancer.
