What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 3 trials are large pivotal studies comparing the treatment to current standard of care or placebo. Your participation directly contributes to the evidence needed for regulatory approval.

This trial targets 717 participants in total. It began in 2025-04-16 with a primary completion date of 2029-04.

Brief Summary

Numerous studies have shown that even when imaging does not reveal the presence of cancer cells, traces of tumor DNA (i.e. originating from cancer cells) can be detected in the blood of certain patients: this is called molecular residual disease (MRD). When such traces are detected (we speak of MRD+ status), the risk of relapse is much higher than when there is no circulating tumor DNA (MRD - status). Given the success of immunotherapy in treating patients with metastatic disease in a variety of tumor types, there is enormous enthusiasm for expanding the use of immunotherapy to people with cancer at an early stage. UMBRELLA is a biology-driven trial designed to study the impact of systemic treatment with tislelizumab monotherapy after detection of MRD+ status after completion of surgery and perioperative treatments in patients with cancer of a solid tumor. Residual disease (MRD) will be determined by optimized detection and precise monitoring of circulating tumor DNA, enabling early detection of recurrence and disease monitoring, including in patients without MRD \[MRD(-)\].

Eligibility Criteria

Inclusion Criteria: 1. Age ≥ 18 years. 2. Completion of surgical and peri-operative treatments as per international guidelines. 3. Subject must have completed standard curative-intent therapy (i.e: Surgery, Neoadjuvant and adjuvant therapy) for minimum 3 months and maximum 4.5 months prior to sending samples for MRD analyses. 4. Subject must not have standard treatment at least 3 weeks before blood sampling for ctDNA analyses. 5. Patients must not have blood transfusion at least 3 months before blood sampling for ctDNA analyses. 6.

Subjects must have sufficient amount of archived primary tumor material for ctDNA and translational research analyses that will be conducted as defined in the protocol. 8.

Subjects must have adequate organ function as indicated by the following laboratory values (obtained within 7 days prior to randomization): 1. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L, platelets ≥ 100 x 109/L, haemoglobin ≥90 g/L. Note: Patients must not have required growth factor support ≤ 14 days before sample collection. 2. International normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 x upper limit of normal (ULN). 3. Activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN. 4. Serum total bilirubin ≤ 1.5 x ULN (total bilirubin must be \< 3 x ULN for patients with Gilbert's syndrome). 5. Aspartate and alanine aminotransferase (AST and ALT) ≤ 3 x ULN. 6. Creatinine clearance ≥60 mL/min for participants with creatinine levels above institutional normal (≥ULN). Creatinine clearance should be calculated per the Cockcroft-Gault formula (or local institutional standard method). 13. Subjects with a social security in compliance with the French law relating to biomedical research (Article L.1121-11 of French Public Health Code). 14. Subjects should understand, sign, and date the written informed consent form prior to any protocol-specific procedures performed. Patient should be able and willing to comply with study visits and procedures as per protocol. 15. Females of childbearing potential must be willing to use a highly effective method of birth control for the duration of the trial, and ≥ 120 days after the last dose of the trial drug and have a negative serum pregnancy test ≤ 7 days of the first dose of the trial drug. A barrier contraceptive method (e.g., condom) is also required. A woman is considered of childbearing potential following menarche and until becoming post-menopausal (≥ 12 months of non-therapy-induced amenorrhea) unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral oophorectomy and bilateral salpingectomy with surgery at least 1 month before the first dose of study drug or confirmed by follicle stimulating hormone (FSH) test \>40 mIU/mL and estradiol \<40 pg/mL (\<140 pmol/L). 16. Nonsterile males must be willing to use a highly effective method of birth control for the duration of the study and for ≥ 120 days after the last dose of the trial drug. A barrier contraceptive method (e.g., condom) is also required. Exclusion Criteria: 1. Participation in another clinical trial with an investigational product during the last 3 to 4.5 months and while on study treatment 2. Any condition which in the Investigator's opinion makes it undesirable for the subject to participate in a clinical trial or which would jeopardize compliance with the protocol, 3. Pregnant or breastfeeding women 4. Subjects under guardianship or deprived of his liberty by a judicial or administrative decision or incapable of giving its consent. 5. Patients with confirmed EGFR (Epidermal Growth Factor Receptor ) exon 19 deletions or exon 21 L858R substitutions are excluded from the study, due to the potential benefit from adjuvant osimertinib treatment, which represents a standard of care for these genetic profiles in non-small cell lung cancer (NSCLC). 6. Treatment with systemic immunostimulatory agents (including but not limited to interferons or interleukin-2) within 4 weeks or five half-lives of the drug, whichever is shorter, prior to enrolment 7. Treatment with systemic immunosuppressive medication (including, but not limited to, corticosteroids, cyclophosphamide, azathioprine, methotrexate and thalidomide) within 2 weeks prior to initiation of study treatment, or anticipation of need for systemic immunosuppressive medication during study treatment, with the following exceptions: * Patients who received acute, low-dose systemic immunosuppressant medication or a one-time pulse dose of systemic immunosuppressant medication (e.g., 48 hours of corticosteroids as premedication for hypersensitivity reaction (e.g., CT scan premedication)) are eligible for the study after Principal investigator approval has been obtained * Patients who received mineralocorticoids (e.g., fludrocortisone), corticosteroids for chronic obstructive pulmonary disease (COPD) or asthma, or low-dose corticosteroids for orthostatic hypotension or adrenal insufficiency are eligible for the study * Patients who received intranasal, inhaled, topical or local steroid injections (e.g., intra articular injection) 8.
