Summary
Oxaliplatin ± nivolumab in combination with trifluridine/tipiracil or 5-fluorouracile (5-FU) in frail patients with advanced, recurrent or metastatic gastric, oesophageal or gastroesophageal junction cancer.
Eligibility
Inclusion Criteria20
- Histologically confirmed locally advanced, recurrent or metastatic non resectable adenocarcinoma of the stomach, oesophagus or gastroesophageal junction (GEJ) ineligible to curative treatment.
- No dysphagia or difficulty in swallowing.
- No overexpression/amplification of HER2 (IHC 0 or 1+; if IHC is 2+, HIS must be negative). Known combined positive scor (CPS) PD-L1 score (result in % with the name of the method used). The microsatellite and mismatch repair (MMR) status of patient's tumour (MSI/MSS and pMMR/dMMR) must also be known at the time of screening (IHC and PCR tests have to be done).
- At least one evaluable lesion according to RECIST v1.1 outside any previously irradiated area.
- No prior palliative chemotherapy.
- Age ≥18 years old.
- Patient eligible for FOLFOX chemotherapy
- Adequate organs function:
- Absolute neutrophils count ≥1.5x10⁹/L
- Platelets count ≥100x10⁹/L
- Haemoglobin ≥9 g/L
- Serum bilirubin levels \<2 times upper limit of normal (ULN), up to 2.5 times ULN in case of hepatic metastasis (biliary drainage allowed)
- Transaminases \<5 times ULN
- Creatinine clearance \>40 mL/min
- No Dihydropyrimidine dehydrogenase (DPD) deficiency (uracilemia \<16 ng/ml)
- Women of childbearing potential must have a negative serum or urine pregnancy test done within 14 days before the first study treatment.
- Patients must agree to use adequate contraception methods for the duration of study treatment and within 6 months after completing treatment.
- Patients must be affiliated to a Social Security System (or equivalent).
- Patient must have signed and dated a written informed consent form prior to any trial specific procedures. When the patient is physically unable to give their written consent, a trusted person of their choice, independent from the investigator or the sponsor, can confirm in writing the patient's consent.
- Availability of archived tumour material for ancillary studies
Exclusion Criteria18
- Patient with a performance status ECOG PS \>2.
- Other current or previous malignancy within the past 3 years (with the exception of squamous cell carcinoma of the skin treated by surgery).
- Adjuvant chemotherapy or radio-chemotherapy completed for less than 6 months.
- Peripheral neuropathy of NCI-CTCAE grade ≥2 at baseline.
- Patients with known allergy or severe hypersensitivity to any of the trial drugs or any of the trial drug excipients.
- Patients unwilling or unable to comply with trial obligations for geographic, social, or physical reasons, or who are unable to understand the purpose and procedures of the trial.
- Previous treatment with trifluridine/tipiracil.
- Known Human Immunodeficiency Virus (HIV) infection.
- Active Hepatitis B virus (HBV, defined as having a positive hepatitis B surface antigen \[HBsAg\] test prior to inclusion) or hepatitis C virus (HCV).
- Interstitial lung disease.
- Prior pneumonitis requiring systemic corticosteroid therapy.
- Active infections.
- Pregnant or breastfeeding woman.
- Participation in another therapeutic trial within the 30 days prior to randomisation.
- Persons deprived of their liberty or under protective custody or guardianship.
- Clinically relevant coronary artery disease or history of myocardial infarction in the last 12 months, or high risk of uncontrolled arrhythmia (for men: QTc ≥450 msec, for women: QTc ≥470 msec)
- Active systemic autoimmune disease. Subjects with vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enrol.
- Subjects with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days prior to first study drug administration. Inhaled or topical steroids are permitted in the absence of active autoimmune disease
Interventions
Trifluridine/Tipiracil will be administered with a 14-day schedule (35 mg/m² BID for 5 days followed by 9 days of recovery) until disease progression or intolerable toxicity.
Oxaliplatin will be administered intravenously on day 1 of each treatment cycle (infusion duration: 2 hours), every 2 weeks. The first cycle will be administered at level -1 (70 mg/m²) and then increased to 85 mg/m² (if feasible) from the cycle 2 to 8 or until disease progression, whatever occurs first. In case of limiting-oxaliplatin neuropathy and in all cases after 8 cycles, oxaliplatin will be stopped and Trifluridine/Tipiracil will be continued alone until disease progression or intolerable toxicity.
Folinic Acid 400 mg/m² (or 200 mg/m² if L-folinic acid) + oxaliplatin 85 mg/m² (infusion duration: 2 hours) followed by 5-FU bolus 400 mg/m² and then 5-FU 2400 mg/m² as a 46-hour continuous infusion. Treatment repeated every 14 days. In case of limiting-oxaliplatin neuropathy and in all cases after 8 cycles, oxaliplatin will be stopped and 5-FU (simplified LV5FU2 regimen) or capecitabine (1000 mg/m² BID during 2 weeks every 3 weeks) will be continued alone until disease progression or intolerable toxicity.
Nivolumab 240 mg (infusion duration 30 minutes, every 2 weeks) until disease progression or intolerable toxicity for a maximum of 2 years
