Intervention / Treatment

Experimental: Arm A - Tislelizumab and SX-682

Drug: Tislelizumab; Patients will receive Tislelizumab (200 mg intravenous) on Day 1 of Cycles 1-6. Cycle 1 will be 14 days long and occur prior to surgery. Cycle 2 will be 14 days long and occur prior to standard of care chemotherapy. Cycles 3-6 will each be 21 days long and will be given after completion of standard of care chemotherapy.; Other Names: BGB-A317; Drug: SX-682; Patients will receive SX-682 (200 mg twice daily by mouth) on Days 1-14 of Cycles 1-2 and Days 1-21 of Cycles 3-6. Cycle 1 will be 14 days long and occur prior to surgery. Cycle 2 will be 14 days long and occur prior to standard of care chemotherapy. Cycles 3-6 will each be 21 days long and will be given after completion of standard of care chemotherapy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Immune response rate as assessed by density of intratumoral granzyme B+ CD137+ T cells	The change in density of intratumoral granzyme B+ CD137+ T cells before and after neoadjuvant treatment with tislelizumab and SX-682.	Baseline and 2 weeks
Pathologic Response Rate as assessed by number of patients with a grade 0-2 pathologic response	The number of patients with a grade 0-2 pathologic response as defined by the College of American Pathologists (CAP) tumor regression grading system.	4 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of participants experiencing grade 3 or above drug-related toxicities	When calculating the incidence of AEs, each AE (as defined by NCI CTCAE v5.0) will be counted only once for a given subject.	4 years
Overall Survival (OS)	OS is defined as the time from the first dose of study treatment to death from any cause. Patients who have not died will be censored at the last date known to be alive. Estimation based on the Kaplan-Meier curve.	4 years
Disease Free Survival (DFS)	DFS is defined as the time from the first dose of study treatment until evidence of disease recurrence or death from any cause. For patients who have not progressed, relapsed, or died at the time of analysis, DFS will be censored on the date of last visit where disease progression was evaluable. Estimation based on the Kaplan-Meier curve.	4 years
