Personalized ctDNA Monitoring for Predicting Immunotherapy Outcomes in Advanced Non-Clear Cell Renal Cell Carcinoma

Korábbi kezelés

• The planned systemic treatment does not contain an immune checkpoint inhibitor and consists only of chemotherapy, targeted therapy, or another non-immunotherapy systemic treatment.
• Another active malignancy of a different primary site or histological type within the previous 3 years, except adequately controlled malignancies such as papillary thyroid carcinoma, basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or cervical carcinoma in situ.
• Major surgery or severe trauma within 4 weeks before enrollment without adequate recovery.
• Uncontrolled severe infection or another serious comorbidity, including active tuberculosis, active hepatitis B or C, severe cardiac insufficiency, persistent symptomatic arrhythmia, uncontrolled hypertension, or serious cardiovascular or cerebrovascular events such as myocardial infarction, unstable angina, or cerebrovascular accident within 6 months before enrollment.

Más betegség

• Severe psychiatric, cognitive, or behavioral impairment that prevents understanding of the study, provision of required samples, or completion of protocol-specified examinations and follow-up.
• Failure to establish a patient-specific ctDNA monitoring panel because of inadequate tumor tissue quantity or quality, inability to identify suitable patient-specific somatic variants, or other technical reasons.
• Any other condition that, in the investigator's judgment, may increase the risks associated with study participation, interfere with interpretation of the study results, or compromise protocol compliance.

Egyéb

• Participants meeting any of the following criteria will be excluded:
• Untreated, symptomatic, or clinically unstable central nervous system metastases or leptomeningeal metastases.
• Pregnancy or breastfeeding.

• Participants must meet all of the following criteria:
• Age 14 years or older, with no restriction based on sex.
• Histologically confirmed renal cell carcinoma classified as non-clear cell renal cell carcinoma. Immunohistochemical or molecular testing may be used when necessary to establish the histological subtype. Eligible subtypes include papillary renal cell carcinoma, chromophobe renal cell carcinoma, TFE3-rearranged renal cell carcinoma, FH-deficient renal cell carcinoma, collecting duct carcinoma, renal medullary carcinoma, and other rare non-clear cell renal cell carcinoma subtypes.
• Unresectable or metastatic renal cell carcinoma with at least one measurable lesion according to RECIST version 1.1.
• Scheduled, according to routine clinical care, to initiate immune checkpoint inhibitor-based systemic therapy, including an immune checkpoint inhibitor combined with targeted therapy, dual immune checkpoint blockade, or immune checkpoint inhibitor monotherapy. The number of previous lines of systemic therapy is not restricted, provided that prior treatment history, specific regimens, and best responses can be adequately documented.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 and an estimated life expectancy greater than 3 months.
• Ability and willingness to provide written informed consent and comply with protocol-specified sample collection, examinations, and follow-up.
