A Phase I, First in Human Study of CBA-1535, T Cell Engager(5T4/CD3/5T4) in Patients With Advanced Solid Tumors.
brief summary
This is a First in Human muticenter, non-randomized, open-label Phase I dose-escalation study of CBA-1535. The study will have 2 parts (Part 1 and Part 2). Part 1 is the dose-escalation cohorts of CBA-1535 single agent theapy. Part 2 is the dose-escalation cohorts of CBA-1535 in combination with Pembrlizumab. This study will evaluate the safety, tolerability, PK, biomarker profiles and preliminary efficacy of CBA-1535.
detailed description
To evaluate safety and efficacy of CBA-1535 in the following two parts in a stepwise manner:
Part 1
\- In Part 1, the primary objective is to evaluate the safety and tolerability of CBA-1535 in patients with solid tumors where no standard treatment is available, or who are intolerant to or non-responders to standard treatments.
Additionally, the PK, biomarker profiles, and preliminary efficacy will be evaluated. The initial dose for Part 2 will also be determined.
Part 2
\- In Part 2, The primary objective is to evaluate the safety and tolerability of CBA-1535 in combination with pembrolizumab in patients with solid tumor where no standard treatment is available, or who are intolerable or non-responder to the standard treatment. Additionally, the PK, biomarker profiles, preliminary efficacy will be evaluated. The recommended Phase 2 dose (R2PD) will also be determined.
