Safety and preliminary efficacy of BNT314 in cancer patients with malignant solid tumors
- Conditions
- Advanced or metastatic malignant solid tumors
- Registration Number
- 2023-506053-38-00
- Lead Sponsor
- BioNTech SE
- Brief Summary
To determine the maximum tolerated dose (MTD) / maximum administered dose (MAD) of BNT314 administered as monotherapy. To establish the safety profile of BNT314 administered as monotherapy.
- Detailed Description
This is a multicenter, multinational safety study in patients with metastatic or advanced malignant solid tumors for whom, at the discretion of the investigator, there is no available standard therapy likely to confer clinical benefit, evaluating the safety, tolerability, preliminary antitumor activity, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of BNT314.
During dose escalation, BNT314 will be administered to patients via one infusion in periodic cycles.
Additional cohorts (backfill cohorts) administering BNT314 as monotherapy will assign patients to specific DLs, based on the emerging safety, PK, and pharmacodynamic data. This would allow for further assessment of dose- and exposure-response relationships for clinical activity, safety, and tolerability to support BNT314 dose optimization.
The treatment period will last until progressive disease (PD), confirmed PD (as per immune response evaluation criteria in solid tumors \[iRECIST\]), unacceptable toxicity, or withdrawal of consent, whichever happens first.
The maximum duration of BNT314 administration in this study is 2 years.
