A wash out of more than 3 weeks is required after last systemic antibiotics to allow reconstitution of the microbiome. Patients infected by HIV but having efficient anti-retroviral therapy and CD4+ T-cell counts >500/mm³ are eligible. Patients with a history of HBV or HCV that are cured and have eligible liver function criteria are also eligible.\n- METAREM: Gastrointestinal disorders or abnormalities that would interfere with absorption of the study drug in case an oral drug is tested in the sub-protocol for which the patient is screened\n- METAREM: Pregnancy or breast feeding.\n- METAREM: History of life threatening autoimmune/immune mediated inflammatory disease, including but not limited to severe colitis, pneumonitis, Guillain-Barré syndrome, anti-phospholipid syndromes and myocarditis. Patients with a history of auto-immune endocrinopathy (hypo/hyper thyroiditis, type 1 diabetes mellitus, …) and who are stable on hormone replacement therapy are eligible for the study. Patients with a history of vitiligo, alopecia areata, cutaneous psoriasis and grade 1-2 Sjogren syndrome are eligible. Hormone replacement therapy with physiological doses of hydrocortisone is acceptable.\n- METAREM: Intake of Ganoderma Lucidum mushroom (also called “Reishi”) and/or herbal remedies and/or traditional medicines within the past weeks prior to start of study treatment or concomitantly with the trial because of their potential to increase treatment related adverse events.\n- METAREM: Any psychological, familial, sociological, geographical factors, lifestyle, behavior, clinical or biological parameters or elements in the past medical history of the patients that, according to the investigator, could preclude the ability of the trial to directly reach its objectives, or indirectly via treatment observance or study follow up. Patients with active alcoholism and/or drug abuse are excluded.\n- METAREM: Person deprived of their liberty or under protective custody or guardianship\n- META-1: Patients who have previously received an anti-PD(L)1 or anti-CTLA4 or anti-LAG- 3 or anti-TIM3 immunotherapy.\n- META-1: Patients with any Hypersensitivity to the active ingredient or to any of the excipients of Pembrolizumab or Cemiplimab.\n- METAREM: Treatment with systemic long-term immunosuppressive medications unless otherwise specified in the specific therapeutic Sub-protocols. Those immunosuppressive drugs must have been stopped at least 4 weeks prior to enrolment.\n- METAREM: Chemotherapy, hormonotherapy, radiotherapy or immunotherapy or therapy with monoclonal antibodies or small tyrosine kinase inhibitors within the past 4 weeks or 5 half-life times (whatever the shortest) prior to treatment with the trial drugs.\n- METAREM: Administration of a live, attenuated vaccine within 4 weeks before registration.\n- METAREM: Radiotherapy to the chosen RECIST target lesion(s) (unless a progression after radiotherapy has been documented).\n- METAREM: Persistence of a clinically relevant treatment-related toxicity from previous chemotherapy, targeted therapy and/or radiotherapy which could hamper the safety or efficacy assessment of the therapy tested (for previous disease).\n- METAREM: Patients with symptomatic brain metastases or leptomeningeal disease are excluded unless otherwise specified by a specific therapeutic Sub-protocol. Clinically asymptomatic brain metastases and clinically asymptomatic leptomeningeal disease are allowed (treatment with steroids prior to initiation of the trial is not allowed).\n- METAREM: Patients with evolving tumors next to cavitary or major blood vessels at high risk of massive bleeding and/or perforation."}
