Detailed Description
PRIMARY OBJECTIVE:
I. To compare three-year event-free survival (EFS) following the administration of perioperative atezolizumab and chemotherapy versus atezolizumab alone in patients with resectable microsatellite instability-high (MSI-H)/mismatch repair deficiency (dMMR) gastric and gastroesophageal junction (GEJ) cancer.
SECONDARY OBJECTIVES:
I. To assess tumor regression grade (TRG) rates following the administration of perioperative atezolizumab and chemotherapy versus atezolizumab in patients with resectable MSI-H/dMMR gastric and gastroesophageal junction (GEJ) cancer.
II. To assess overall survival (OS) following the administration of perioperative atezolizumab and chemotherapy versus atezolizumab in patients with resectable MSI-H/dMMR gastric and gastroesophageal junction (GEJ) cancer.
III. To assess the toxicity associated with the administration of perioperative atezolizumab and chemotherapy versus atezolizumab in patients with resectable MSI-H/dMMR gastric and gastroesophageal junction (GEJ) cancer.
IV. To correlate circulating tumor-derived deoxyribonucleic acid (ctDNA) clearance (defined as > 50% reduction or a reduction to undetectable levels) with TRG, EFS and OS.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A:
NEOADJUVANT THERAPY: Patients receive physician's choice of chemotherapy regimen consisting of 4 cycles of docetaxel intravenously (IV), oxaliplatin IV, leucovorin calcium IV, and fluorouracil IV (FLOT) or 4 cycles of oxaliplatin IV, leucovorin calcium IV, and fluorouracil IV (mFOLFOX) or 3 cycles of oxaliplatin IV and capecitabine orally (PO) (CAPOX) in addition to atezolizumab IV on study.
SURGERY: Patients undergo surgery with lymphadenectomy on study.
ADJUVANT THERAPY: Patients receive FLOT, mFOLFOX, or CAPOX and atezolizumab IV as in Neoadjuvant Therapy and then receive atezolizumab IV alone.
ARM B:
NEOADJUVANT THERAPY: Patients receive 3 cycles of atezolizumab IV on study.
SURGERY: Patients undergo surgery with lymphadenectomy on study.
ADJUVANT THERAPY: Patients receive 9 cycles of atezolizumab IV on study.
All patients also undergo computed tomography (CT) or magnetic resonance imaging (MRI) throughout the trial. Patients may optionally undergo positron emission tomography (PET)/CT and/or collection of blood samples throughout the trial. Patients may also undergo echocardiography (ECHO) throughout the trial as clinically indicated.
Patients are followed up for 10 years from the date of randomization.

Live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, yellow fever, rabies, Bacillus Calmette-Guerin (BCG), and typhoid (oral) vaccine. Patients are permitted to receive inactivated vaccines and any non-live vaccines including those for the seasonal influenza and coronavirus disease 2019 (COVID-19) (Note: intranasal influenza vaccines, such as Flu-Mist [registered trademark] are live attenuated vaccines and are not allowed). If possible, it is recommended to separate study drug administration from vaccine administration by about a week (primarily, in order to minimize an overlap of adverse events)
Patient must not have active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including systemic corticosteroids. These include but are not limited to patients with a history of immune related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain- Barre syndrome, myasthenia gravis; systemic autoimmune disease such as systemic lupus erythematosus (SLE), connective tissue disease, scleroderma, inflammatory bowel disease (IBD), Crohn's, ulcerative colitis and hepatitis.

- Patient must not have had an allogeneic bone marrow/stem, cell or solid organ transplant
- Patient must not have a history or current evidence of any condition (e.g., known deficiency of the enzyme dihydropyrimidine dehydrogenase [DPD]), therapy, or laboratory abnormality that might confound the results of the trial, interfere with the patient's participation for the full duration of the trial, or is not in the best interest of the patient to participate, in the opinion of the treating investigator
- Patient must not have any condition that would interfere with the cooperation with the requirements of this trial
Patient must not be pregnant or breast-feeding due to the potential harm to an unborn fetus and possible risk for adverse events in nursing infants with the treatment regimens being used

- Patient must not expect to conceive or father children by using accepted and effective method(s) of contraception or by abstaining from sexual intercourse while on protocol treatment. Patients of childbearing potential must continue contraception measures for 5 months after the last dose of atezolizumab and for 9 months after the last dose of chemotherapy. Male patients with partners of childbearing potential must continue contraception measures for 6 months after the last dose of chemotherapy. Patients of childbearing potential must also not breastfeed while on treatment and for 5 months after the last dose of atezolizumab and for 3 months after the last dose of chemotherapy

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Event-free survival (EFS)
Time Frame: From randomization to systemic progression of disease that precludes surgery or distant recurrence, or death due to any cause, assessed up to 3 years
|
EFS is defined as the time from randomization to an unfavorable event.
Hence, occurrences such as local, resectable recurrences, patients' refusal for surgery of resectable tumor, or patients' undergoing definitive therapy such as salvage surgery would not be counted as events for EFS.
|
From randomization to systemic progression of disease that precludes surgery or distant recurrence, or death due to any cause, assessed up to 3 years
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Tumor regression grade (TRG)
Time Frame: Up to 10 years
|
Will be assessed in the primary tumor using Becker's grading criteria.
Fisher's exact test will be used to compare the TRG across the arms.
|
Up to 10 years
|
Overall survival (OS)
Time Frame: From randomization to death from any cause, assessed up to 10 years
|
The stratified log rank test will be used to compare OS across the arms.
|
From randomization to death from any cause, assessed up to 10 years
|
Incidence of adverse events
Time Frame: Up to 10 years
|
All adverse events will be graded using the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.
Formal comparison (hypothesis testing) of toxicity rates across the arms is not a primary goal of this trial and the sample size of 240 patients will provide sufficient power for detecting only relatively large differences in adverse events.
|
Up to 10 years
|
Circulating tumor-derived deoxyribonucleic acid (ctDNA)
Time Frame: Up to 10 years
|
The proportion of ctDNA clearance on each arm would be correlated with time-to-event (EFS and OS) and binary (TRG) data of the trial.
For correlating ctDNA clearance rates and time-to-event data, cox-regression would be used to estimate the correlation magnitude.
For correlating ctDNA and binary data, proportions of ctDNA clearances will be compared.

Up to 10 years
