Официальное название

A Multicenter Randomized Open-Label Trial Evaluating ctDNA-Guided Interruption Versus Standard of Care Continuous Immune-Checkpoint Inhibitor (ICI) Therapy In Patients With Advanced/Metastatic Solid Tumors

Обзор

This is a multicenter, open-label, randomized (1:1) trial designed to evaluate whether ctDNA-guided interruption of immune-checkpoint inhibitor (ICI) therapy provides comparable survival to standard of care (SoC) continuous ICI therapy in patients with histologically confirmed advanced/metastatic non-small cell lung cancer (NSCLC), melanoma, microsatellite instability-high (MSI-High)/Deficient Mismatch Repair (dMMR) colorectal cancer (CRC), renal cell carcinoma (RCC) and other solid tumors. This study will be conducted in up to 100 sites.

Вмешательства

• Устройство Signatera Genome ultra-sensitive ctDNA blood test
  The test is used to monitor for disease recurrence.

Первичные конечные точки

• To demonstrate that ctDNA-guided intermittent ICI therapy results in at least 50% of patients who do not reinitiate systemic therapy prior to 6 months from randomization. [Срок оценки: 6 months from randomization]
• To demonstrate that ctDNA-guided intermittent ICI therapy is non-inferior to SoC continuous ICI therapy as measured by 36 month OS in advanced/metastatic solid tumor patients. [Срок оценки: 3 years from randomization to death from any cause]

Вторичные конечные точки (2)

• To compare ctDNA-guided intermittent ICI therapy to SoC continuous ICI therapy as measured by 36 month progression-free survival (PFS) (blinded independent central review [BICR] assessed) in advanced/metastatic solid tumor patients. [Срок оценки: 3 years from randomization to the first occurrence of disease progression measured by RECIST 1.1 or death from any cause, whichever occurs first]
• To compare the tolerability between the ctDNA-guided intermittent ICI therapy and SoC continuous ICI therapy using the Common Terminology Criteria for Adverse Events (CTCAE) v6.0. [Срок оценки: From randomization to Year 3]

• Coagulation: INR or PT, activated partial thromboplastin time (APTT) ≤1.5×ULN Note: Laboratory assessments performed as part of standard of care evaluations during immunotherapy treatment administration may be used to satisfy these eligibility criteria, provided they are obtained within 28 days of enrollment.
• Recovery to baseline or ≤ Grade 1 common terminology criteria for adverse events (CTCAE) v6 from AE(s) related to any prior treatments unless AE(s) are deemed clinically non-significant (e.g., Grade 2 alopecia) by the Investigator and/or stable on supportive therapy.
• No prior malignancy, with the exception of basal cell carcinoma of the skin, superficial bladder cancer, squamous cell carcinoma of the skin, or in situ cancer, or has undergone potentially curative therapy with no evidence of that disease recurrence for 5 years since completion of definitive therapy
• Participants must be willing and able to comply with study visits, treatment plans, laboratory tests, and other study procedures
• Women of child-bearing potential (WOCBP) and male participants partnering with WOCBP must agree to use highly effective contraception during the treatment phase and at least 180 days post last dose
• Patients must be willing to discontinue clinically-directed ctDNA testing for treatment response monitoring during the period of clinical trial testing as dictated by the protocol.

Критерии исключения

Patients are not eligible for the study if they meet any of the following criteria, as assessed by the investigator:

• Available alternate treatment options with curative intent, e.g. surgery and / or RT and / or Chemotherapy.
• Symptomatic or progressing CNS metastases; or presence of leptomeningeal disease.
• Patient has active autoimmune disease that required systemic treatment in the past 2 years, is immunocompromised in the opinion of the Investigator, or is receiving systemic immunosuppressive treatment. (Note: Participants with splenectomy are allowed.) Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc) is not considered a form of systemic treatment.
• Patient is receiving systemic steroid therapy ≤3 days prior to enrollment or receiving any other form of immunosuppressive medication with the exception of daily steroid replacement therapy. Note: Use of inhaled corticosteroids, local steroid injection, or steroid eye drops is allowed.
• Had allogeneic tissue/solid organ transplantation.
• Interstitial lung disease or history of pneumonitis that has required oral or IV steroids. Note: Patients with lymphangitic carcinomatosis secondary to NSCLC can be considered as eligible.
• Has received or will receive a live vaccine within 30 days prior to enrollment (seasonal flu vaccines that do not contain live vaccine are permitted).
• Active infection requiring intravenous systemic therapy.
• Known history of human immunodeficiency virus (HIV).
• Known active Hepatitis B or C.
• Pregnant, breastfeeding, or expecting to conceive or father children within the projected duration of the study.
• Currently participating or has participated in a study of an investigational agent or using an investigational device within 4 weeks of enrollment.
• Use of any commercial ctDNA or liquid biopsy monitoring outside of the study protocol during the treatment monitoring phase within the protocol.
