About this trial

This is a first-in-human (FIH), open-label, multiple-site, dose escalation study which will evaluate the safety, tolerability, pharmacokinetics (PK), and immunogenicity of increasing doses of BNT317 in participants with advanced solid tumors.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Have histologically or cytologically confirmed advanced tumors, who have failed standard therapy, or for whom no standard treatment option is available, or for whom standard therapy is not appropriate.

Have at least one measurable lesion based on RECIST 1.1. Lesions treated after prior local treatment (radiotherapy, ablation, interventional procedures, etc.) are generally not considered as target lesions. If the lesion with prior local treatment is the only targeted lesion, evidence-based radiology must be provided to demonstrate disease progression (the single bone metastasis or the single central nervous system [CNS] metastasis should not be considered as a measurable lesion).

Adequate hematologic and organ function.

Disqualifiers

Any prior treatment which inhibits cluster of differentiation 39 (CD39).

Vaccination with live attenuated vaccine(s) within 4 weeks prior to the first dose of IMP.

Any investigational product within 4 weeks or 5 half lives (if the half life of the other investigational product is known), whichever is longer, before the first dose of IMP in this study or ongoing participation in the active treatment phase of another interventional clinical study.

Systemic cytotoxic chemotherapy, immunotherapy within 3 weeks or five half-lives of the chemotherapy (whichever is shorter) prior to the first dose of IMP.

Trial outcomes

Primary outcomes

1

Occurrence of DLTs

Per dose group. During the DLT observation period.

Time frame
up to 28 days post IMP administration on Day 1 of Cycle 1 or the day before Cycle 3 Day 1, whichever comes earlier (each cycle is 14 days)
2

Occurrence of treatment emergent adverse events (TEAEs) and treatment related adverse events (TRAEs)

Per dose group. Assessed according to (US National Cancer Institute) Common Terminology Criteria for Adverse Events version 5.0, including Grade ≥3, serious, fatal TEAE by relationship.

Time frame
from first IMP administration up to 100 days after last dose of IMP or until a new anticancer therapy is initiated
3

Occurrence of dose interruption or discontinuation of study treatment due to TEAEs

Per dose group.

Time frame
from first IMP administration up to 14 days after the last dose of IMP
4

MTD or the recommended phase two dose (RP2D) of BNT317

Time frame
For MTD, up to 28 days post IMP administration on Cycle 1 Day 1 or the day before Cycle 3 Day 1, whichever comes earlier (each cycle is 14 days) or, for RP2D, up to 100 days

Secondary outcomes

1

Objective Response Rate (ORR)

Per dose group. Defined as the proportion of participants in whom a complete response (CR) or partial response (PR) (per Response Evaluation Criteria in Solid Tumors version 1.1 \[RECIST v1.1\]) is observed as best overall response.

Time frame
from first IMP administration up to 100 days after last dose of IMP or until a new anticancer therapy is initiated
2

Duration of Response (DOR)

Per dose group. Defined as the time from first objective response (CR or PR per RECIST v1.1) to first occurrence of objective tumor progression (progressive disease per RECIST v1.1) or death from any cause, whichever occurs first.

Time frame
from first IMP administration up to 100 days after last dose of IMP or until a new anticancer therapy is initiated
3

Disease Control Rate (DCR)

Per dose group. Defined as the proportion of participants with confirmed CR or PR or stable disease (per RECIST v1.1) is observed as best overall response.

Time frame
from at least 6 weeks after the first IMP dose up to 100 days after last dose of IMP or until a new anticancer therapy is initiated
4

PK assessment: The maximum (peak) serum concentration (Cmax) of BNT317

Per dose group. If data permits.

Time frame
from pre-dose Cycle 1 to pre-dose Cycle 4 (each cycle is 14 days)
