Clinical Trial Summary

This is a study to investigate the safety and efficacy of an investigational OBX-115 regimen in adult participants with advanced solid tumors.


Clinical Trial Description

Primary Objective (Phase 1): • Assess the safety and tolerability of OBX-115 regimen Primary Objective (Phase 2): • Evaluate preliminary efficacy of OBX-115 regimen as measured by the investigator using objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 Secondary (Phase 1): • Assess preliminary efficacy of OBX-115 regimen by evaluating ORR Secondary (Phase 2): • Evaluate safety and tolerability of OBX 115 based on the collected AE data Secondary (both Phase 1 and Phase 2): - Evaluate duration of response (DOR): To evaluate the duration from the time that criteria are met for CR or PR per RECIST v1.1 as assessed by the investigator until disease progression or death due to cancer. - Evaluate disease control rate (DCR): To evaluate the percentage of participants with a best overall confirmed response of CR or PR at any time plus stable disease (SD) for at least 4 weeks per RECIST v1.1 as assessed by the investigator. - Evaluate progression-free survival (PFS): To evaluate the time from the date of OBX-115 infusion until disease progression per RECIST v1.1 as assessed by the investigator or death due to any cause. - Evaluate overall survival (OS): To evaluate the time from the date of OBX-115 infusion to death due to any cause - Evaluate feasibility of the manufacturing process: Evaluated as the proportion of OBX-115 products initiated for manufacturing that pass release criteria for infusion. ;
