Oesophageal Adenocarcinoma, Gastric Adenocarcinoma
Conditions
Brief summary
Immunotherapy with anti-PD1 antibodies provides encouraging results on a subset of patients. Capmatinib, a MET inhibitor, has shown an imunomodulatory effect and a synergy with spartalizumab a PD-1 inhibitor. The purpose of this phase II trial is to evaluate the efficacy and safety of the combination of capmatinib + spartalizumab in adult patients with advanced oesogastric adenocarcinoma.
Interventions
Capmatinib 400mg BID for a maximum of 12 months or until progression, patient's refusal or unacceptable toxicity
Spartalizumab 300mg Q3W for a maximum of 12 months or until progression, patient's refusal or unacceptable toxicity

Multicenter single-arm adaptive phase II trial with 2 cohorts according to MET amplification level : * Cohort 1: tumor without MET amplification (\< 6 copies); * Cohort 2: tumor with MET amplification (≥6 copies).

Exclusion criteria
* Previous treatment with immunotherapy or MET inhibitor * Impossibility to take oral medication * Persistent toxicities related to prior treatment of grade greater than 1 * Presence or history of another malignant disease that has been diagnosed and/or required therapy within the past 3 years.
