This is an open-label, multisite Phase I dose escalation, safety, pharmacokinetics (PK) and pharmacodynamics (PD) trial of BNT152+153 in various solid tumor indications.
The clinical trial will enroll patients with various solid tumors that are metastatic or unresectable for whom there is no available standard therapy likely to confer clinical benefit, or patients who are not candidates for such available therapy.
The trial consists of Part 1 and Part 2 with adaptive design elements:
Part 1 consists of Groups A and B.
- Group A is a BNT153 monotherapy dose escalation in patients with advanced solid malignancies until the maximal tolerated dose (MTD) is defined. If MTD is not reached, maximum administered dose (MAD) may be used for further development (or another dose as determined by the safety review committee [SRC]).
- Group B is a BNT152 monotherapy dose escalation in patients with advanced solid malignancies until the MTD or optimal biological dose (OBD; the lowest safe dose associated with optimal biological activity) is defined, whichever occurs earlier.
- Group A will be activated first while the time point for Group B activation is at sponsor's decision.
- This trial also plans to implement biomarker expansion cohorts after BNT153 and/or BNT152 dose escalation is completed. The Biomarker Cohorts will recruit patients at selected sites.
- Part 2 will start once the MTD/MAD have been established for BNT153 and OBD for BNT152 in Part 1.
