Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Locally Advanced or Metastatic Solid Tumors for Phase 1,Dose Escalation and Phase 2 Safety Lead-in, HNSCC, NSCLC and RCC Participants for Phase 2 Drug: BGB-A425 Drug: Tislelizumab Drug: LBL-007 Phase 1 Phase 2

Detailed Description:

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.

Outcome Measures
Go to

Primary Outcome Measures :
  1. Phase 1 Dose Escalation and Phase 2 Safety lead-in: Number of Participants with Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) [ Time Frame: Approximately 2 years ]

    A TEAE is defined as an AE that had an onset date or a worsening in severity from baseline (pretreatment) on or after the first dose of study drug up to 30 days following study drug discontinuation or initiation of new anticancer therapy, whichever comes first.

    An SAE is any untoward medical occurrence that at any dose results in death or is life threatening.


  2. Phase 1 Dose Escalation: Maximum Tolerated Dose (MTD) [ Time Frame: Approximately 2 years ]
