Phase 1-2 Study Investigating Safety, Tolerability, Pharmacokinetics and Preliminary Antitumor Activity of Various Combinations of BGB-A425 and LBL-007 With Tislelizumab in Patients With Advanced Solid Tumors
This is an open-label, multicenter, nonrandomized Phase 1 and 2 clinical trial evaluating various combinations of BGB-A425 and/or LBL-007 with tislelizumab.
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.
TIM3, LAG3, and PD-1 function as immune checkpoint receptors in the overlapping regulation of immune tolerance and have been shown to be co-overexpressed on the tumor infiltrating lymphocytes (TILs) from the participant samples of various solid tumors. Furthermore, emerging clinical data and preclinical data demonstrate co-expression of Tim-3, LAG-3, PD-1 often yield T cells' exhausted immunophenotype (ie, cytokine expression, proliferation etc.). Cancer cells take advantage of PD-1, TIM-3, and LAG-3 in inhibiting immune cells' function, and escape the immune surveillance. Based upon the overlapping expression profiles and immuno-regulatory functions, TIM-3 and LAG-3 mediated adaptive resistance, there is strong scientific rationale that simultaneous targeting of these checkpoint blockers, could potentially increase therapeutic benefit and may help to overcome the resistance arising due to anti-PD-(L)-1 therapy. Hence, this study will evaluate the safety and preliminary efficacy of BGB-A425 (anti TIM-3), LBL-007 (Anti-LAG-3) in combination with tislelizumab (anti PD-1) in patients 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 safety lead-in will determine the RP2D for the combination of BGB-A425, Tislelizumab and/or LBL-007. Phase 2 dose expansion will continue to evaluate the safety but also focus on the efficacy of the doublet or triplet treatment combination in select tumor types.
