Description

Summary

BGB-A425 is a humanized, immunoglobulin gamma-1 (IgG1)-variant monoclonal antibody against TIM-3. Tislelizumab is a humanized, immunoglobulin G4 (IgG4)-variant monoclonal antibody against PD-1. This study tests the safety and anti-tumor effect of BGB-A425 in combination with tislelizumab in participants with advanced solid tumors.

Official Title

Phase 1-2 Study Investigating Safety, Tolerability, Pharmacokinetics and Preliminary Antitumor Activity of Anti-TIM-3 Monoclonal Antibody BGB-A425 in Combination With Anti-PD-1 Monoclonal Antibody Tislelizumab in Patients With Advanced Solid Tumors

Details

Blocking antibodies targeting PD-1 have achieved remarkable results in the treatment of many types of tumors. However, based upon the rate of primary and secondary resistance to PD-1 blockade, it is apparent that additional immuno-regulatory mechanism(s) underlie tumor immune escape. Indeed, research shows that the TIM-3 pathway cooperates with PD-1 to maximize the suppression of effector TILs as well as promote resistance to anti-PD-1 therapy. Therefore, TIM-3 represents an ideal target with the potential to significantly improve and/or extend the therapeutic benefit of anti-PD-1 therapy to a greater number of patients. TIM-3 and PD-1 function as immune checkpoint receptors in the overlapping regulation of immune tolerance and have been shown to be overexpressed on the tumor infiltrating lymphocytes (TILs) from participant samples of various solid tumors including, but not limited to non-small cell lung cancer, head and neck squamous cell carcinoma, renal cell carcinoma, hepatocellular carcinoma, and gastric carcinoma. Subsequently, the activation of TIM-3 and PD-1 represent TILs from both participants or animals across solid tumor types with the most exhausted immunophenotype (ie, cytokine expression, proliferation etc.), which can be reversed with combined blockade of TIM-3 and PD 1. The overlap in expression and function indicates that TIM-3 and PD-1 cooperate to promote effector cell exhaustion which may impede an effective antitumor immune response. Based upon the overlapping expression profiles and immuno-regulatory functions, the improved in vivo antitumor effects, as well as the potential for TIM-3 mediated adaptive resistance, there is strong scientific rationale to evaluate the antitumor effects derived from the combined blockade of TIM-3 and PD-1 in advanced solid tumors. Accordingly, this study will evaluate the safety and preliminary efficacy of BGB-A425 (anti TIM-3) in combination with tislelizumab (anti PD-1) in participants with advanced solid tumors. This is an open-label, multicenter, nonrandomized Phase 1 and Phase 2 clinical trial. Phase 1 will determine the Recommended Phase 2 Dose (RP2D) for the combination of BGB-A425 and tislelizumab. Phase 2 will continue to evaluate the safety but also focus on the efficacy of the combination in select tumor types.
