A Study to Explore the Efficacy and Safety of Atezolizumab Plus Tiragolumab and Chemotherapy in 1st Line HER2 Negative Unresectable, Recurrent or Metastatic Gastric Cancer or Adenocarcinoma of Gastroesophageal Junction (GEJ)
March 7, 2024 updated by: Hoffmann-La Roche
A Phase II, Single-Arm Study to Explore the Efficacy and Safety of Atezolizumab Plus Tiragolumab and Chemotherapy in 1st Line HER2 Negative Unresectable, Recurrent or Metastatic Gastric Cancer or Adenocarcinoma of Gastroesophageal Junction (GEJ)
This study is designed to evaluate the efficacy and safety of atezolizumab plus tiragolumab in combination with capecitabine plus oxaliplatin (XELOX) for first-line treatment in participants with HER2-negative unresectable advanced, recurrent or metastatic gastric cancer (GC) or gastroesophageal junction adenocarcinoma (GEJ AC).

Description
Inclusion Criteria:
- Histologically confirmed (by enrolling center) gastric cancer or adenocarcinoma of GEJ (Siewert I-III)
- Unresectable locally advanced, unresectable recurrent, or metastatic disease that meets the following criteria: a) No prior systemic treatment for advanced disease, b) For patients receiving prior chemoradiotherapy or chemotherapy in the adjuvant or neoadjuvant setting, with an interval of at least 6 months between the final treatment and the diagnosis of advanced disease
- Measurable disease per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) as determined by investigator assessment
- Availability of a representative tumor specimen that is suitable for determination of PD-L1 and TIGIT expression
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
- Life expectancy >/=3 months
- Adequate hematologic and end-organ function
- For women of childbearing potential: agreement to refrain from heterosexual intercourse or use contraception, and agreement to refrain from donating eggs
- For men: agreement to refrain from heterosexual intercourse or use contraceptive methods, and agreement to refrain from donating sperm.
Exclusion Criteria:
- HER2-positive by local review, defined as either immunohistochemistry (IHC) score of 3+ or IHC 2+ with amplification proven by in situ hybridization (ISH) as assessed based on pretreatment tumor tissues
- Use of Chinese herbal medicine or Chinese patent medicines to control cancer within 7 days prior to initiation of study treatment
- Higher risk of bleeding or fistula caused by GEJ Siewert I invading adjacent organs

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Atezo + Tira + XELOX
Atezolizumab plus tiragolumab in combination with XELOX (oxaliplatin and capecitabine) will be administered during Cycles 1-4 (each cycle is 21 days).
During Cycle 5 and beyond atezolizumab and tiragolumab will be administered on Day 1 of each 21-day cycle.
Participants will receive study treatment until disease progression, unacceptable toxicity or loss of clinical benefit as determined by the investigator.
|
Atezolizumab 1200 mg will be administered intravenously (IV) on Day 1 of each 21-day cycle.
Other Names:
Tiragolumab 600 mg will be administered IV on Day 1 of each 21-day cycle.
Oxaliplatin 130 mg/m^2 will be administered IV on Day 1 of each 21-day cycle during Cycles 1-4.
Capecitabine 1000 mg/m^2/d will be administered orally (PO) twice daily (bid) on Days 1-14 during Cycles 1-4.
