Detailed Description
This study is a phase II, multicenter, open-label, multi-cohort proof-of-concept study designed to evaluate the safety and efficacy of Ezabenlimab combined with BI 907828 in patients with unresectable, locally advanced or metastatic solid tumors.
Inclusions will proceed independently for 2 cohorts of patients with TP53 wild-type and TLS+ tumors (TLS: tertiary lymphoid strucutres), as follows:
-
Cohort A: soft-tissue sarcomas
-
Single-arm phase II trial
-
2-stage optimal Simon's design (Simon, 1989)
-
Primary endpoint: is Disease Control Rate (DCR) within 24 weeks of treatment onset, as per RECIST v1.1.
-
Cohort B: Solid tumors [non-small cell lung cancer (NSCLC) or triple negative breast cancer (TNBC) or MMS colorectal cancer (MSS-CCR) or biliary tract cancer (BTC)]
-
Single-arm phase II trial
-
2-stage optimal Simon's design (Simon, 1989)
-
Primary endpoint: is Disease Control Rate (DCR) within 24 weeks of treatment onset, as per RECIST v1.1.

Outcome Measures
Primary Outcome Measures
- Disease control rate (DCR) [6 months]
Disease control rate (DCR), defined as the proportion of patients with disease control lasting for at least 24 weeks since treatment onset, will be reported.
Secondary Outcome Measures
- Objective response rate [6 months]
Objective response rate (ORR), defined as the proportion of patients with objective response will be assessed, based on centralized radiological review, within 24 weeks of treatment onset.
- Duration of response (DoR) [1 year]
Duration of response (DoR) defined as the time from documentation of tumor response (CR, Cru, PR, PRu) to disease progression (as per RECIST V1.1).
- Progression-free survival (PFS) [1 year]
Progression-free survival (PFS) defined as the time from the first day of treatment to the first documented disease progression (as per RECIST v1.1) or death (due to any cause), whichever occurs first.
- Overall survival [1 year]
Overall survival defined as the time from the first day of treatment to death (due to any cause).
- Safety and tolerability of the combination [Throughout treatment period, an expected average of 6 months]
Occurence of adverse events (AEs) and Serious adverse events (SAEs)
