Tislelizumab in Combination With Pre-operative CRT Versus SOC for Locally Advanced G/GEJ Adenocarcinoma
Tislelizumab in Combination With Pre-operative Chemoradiotherapy Versus SOC for Patients With Locally Advanced Gastric/Gastroesophageal Junction Adenocarcinoma: a Multicenter, Randomized, Open-label, Phase IIB Trial
The purpose of this study is to evaluate the efficacy of Tislelizumab in the neoadjuvant (prior to surgery) or adjuvant (after surgery) treatment of previously untreated adults with gastric and gastroesophageal junction (GEJ) adenocarcinoma.
The primary study hypotheses are that:
Neoadjuvant and adjuvant Tislelizumab plus chemoradiotherapy, followed by adjuvant Tislelizumab and chemotherapy is superior to neoadjuvant chemoradiotherapy or chemotherapy, followed by adjuvant chemotherapy in terms of rate of Pathological Complete Response (pathCR) at the time of surgery.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pathological Complete Response (pathCR) Rate
Time Frame: Up to approximately 22 weeks
|
PathCR rate is defined as the percentage of participants having a pathCR.
pathCR is defined as no invasive disease within an entirely submitted and evaluated gross lesion, and histologically negative nodes.
|
Up to approximately 22 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Event-free Survival (EFS) Per Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
Time Frame: Up to approximately 2 years
|
EFS is based on RECIST 1.1 as assessed by the investigator and is defined as the time from randomization to the first of the following events: radiographic disease progression per RECIST 1.1; local or distant recurrence as assessed by CT scan or biopsy if indicated (for participants who are disease free after surgery); clinical progression as evidenced by peritoneal carcinomatosis confirmed by preoperative laparoscopy or laparotomy (for participants who are confirmed to be free of peritoneal involvement by laparoscopy at screening); or death due to any cause.
A second primary malignancy, or radiographic progressive disease (PD) during the neoadjuvant phase that does not preclude successful surgery (i.e., disease free after surgery), are not considered EFS events.
|
Up to approximately 2 years
|
Overall Survival (OS)
Time Frame: Up to approximately 2 years
|
OS is defined as the time from randomization to death due to any cause.
|
Up to approximately 2 years
