Overview
Brief Summary
This was an open label, multicenter, Phase 2 study designed to assess the efficacy and safety of tislelizumab in combination with fruquintinib in participants with advanced or metastatic, unresectable gastric cancer (GC), or colorectal cancer (CRC) or non-small cell lung cancer (NSCLC). The study was conducted in 2 parts. Part 1 was the safety run-in stage to determine dose-limiting toxicity (DLT) and recommended Phase 2 dose (RP2D). Part 2 assessed the preliminary efficacy of tislelizumab in combination with fruquintinib in participants as measured by the overall response rate (ORR) and other efficacy and safety profiles.
Detailed Description
This was an open label, multicenter, Phase 2 study designed to assess the efficacy and safety of tislelizumab in combination with fruquintinib in patients with advanced or metastatic, unresectable GC, and CRC or NSCLC. The study was conducted in 2 parts. Part 1 of the study was the safety run-in stage which assessed dose-limiting toxicities (DLTs) and RP2D. Part 2 began at RP2D. Participants enrolled in Part 1 at RP2D were counted towards Part 2; up to approximately 30 patients per cohort were enrolled at RP2D. The primary outcome measure of the study was ORR as assessed by the investigator as per response evaluation criteria in solid tumors (RECIST) version (v) 1.1. Tislelizumab and fruquintinib were administered until disease progression, intolerable toxicity, death, withdrawal of consent or until the study terminates.

Arms & Interventions
Gastric Cancer (GC): Tislelizumab and Fruquintinib
Participants with advanced or metastatic, unresectable GC received fruquintinib 5 milligrams (mg) daily (3 weeks receiving fruquintinib followed by 1 week off) in combination with tislelizumab 300 mg intravenously on Day 1 of every 4-week cycle (each cycle of 28-days) until disease progression, unacceptable toxicity, or withdrawal for other reasons, whichever occurred first.
Intervention: Tislelizumab

Outcomes
Primary Outcomes
Part 1: Number of Participants With Dose Limiting Toxicities (DLTs)
Time Frame: Up to 28 Days
A DLT was defined as 1 of the following toxicities (Grade 3 or 4 Hematologic or Nonhematologic toxicities) occurring during the DLT assessment window and considered by the investigator to be related to 1 or more study drugs. All toxicities or adverse events (AEs) were graded according to the National Cancer Institute-Common Terminology Criteria for Adverse Events version 5.0 (NCI-CTCAE v5.0).
Part 1: Recommended Phase 2 Dose (RP2D)
Time Frame: Up to 28 Days
RP2D for Part 2 was determined by evaluating safety and DLTs in Part 1 participants.
Objective Response Rate (ORR) as Assessed by the Investigator Based on Response Evaluation Criteria in Solid Tumors (RECIST) Version (v)1.1
Time Frame: From date of randomization until the date of first documented progression or death from any cause, whichever came first (up to 2 years and 9 months)
ORR was defined as the percentage of participants achieving a best overall response (BOR) of complete response (CR) or partial response (PR). Per RECIST v1.1., CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<) 10 millimeters (mm). PR was defined as at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
Secondary Outcomes
- Duration of Response (DOR) as Assessed by The Investigator Based on RECIST v1.1(From the first objective response to the date of first documentation of disease progression or death, whichever occurs first (up to 2 years and 9 months))
- Progression-Free Survival (PFS) as Assessed by Investigator Based on RECIST v1.1(From date of first dose of study drug until the date of first documented progression or death from any cause, whichever came first (up to 2 years and 9 months))
- Overall Survival (OS)(From the first dose of the study treatment to date of death from any cause (up to 2 years and 9 months))
- Disease Control Rate (DCR) as Assessed by the Investigator Based on RECIST v1.1(From date of randomization until the date of first documented progression or death from any cause, whichever came first (up to 2 years and 9 months))
- Clinical Benefit Rate (CBR) as Assessed by the Investigator Based on RECIST v1.1(From date of randomization until the date of first documented progression or death from any cause, whichever came first (up to 2 years and 9 months))
