New trial aims to boost survival in kidney cancer by combining radiation with drug therapy
NCT ID NCT06726421
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase III trial is testing whether adding a precise type of radiation (SBRT) to standard drug therapy (targeted drugs and/or immunotherapy) can help people with kidney cancer that has spread to up to five spots live longer without the disease getting worse. The study will enroll 252 participants and compare the combination approach to drug therapy alone. Researchers will also track side effects and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Stereotactic body radiotherapy (SBRT) plus standard systemic therapy (targeted drugs and/or immunotherapy)
- What this could lead to
- If it works, this could show that adding precise radiation to standard drugs helps people with limited kidney cancer spread live longer without progression.
- What could go wrong
- This is an early-stage Phase III trial with 252 participants, so results may not apply to everyone. Adding radiation may increase side effects without clear benefit.

Inclusion Criteria: * Pathologically confirmed diagnosis of renal cell carcinoma of any histology * Age ≥ 18 years. * ECOG performance status of 0-2. * Imaging suggests the presence of distant metastases, with no more than 5 metastatic lesions according to RECIST 1.1 criteria and MDA standards. * The patient has received local therapy to primary site, including surgery, stereotactic radiotherapy, or ablation. * The patient has received no more than 2 lines of systemic therapy. * No significant impairment of major organ function: Hemoglobin (HB) ≥ 80 g/L Absolute neutrophil count (ANC) ≥ 1.5 × 10⁹/L Platelets (PLT) ≥ 75 × 10⁹/L Serum total bilirubin ≤ 1.5 × ULN Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 × ULN Prothrombin time (PT) and activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN Exclusion Criteria: * Presence of intracranial metastases. * Target lesions have previously received high-dose irradiation with . * Target lesions are unsuitable for radiation therapy judged by treating radiation oncologist (e.g., lesions invading the gastrointestinal tract or penetrating the bronchus). * Uncontrollable metastatic pleural effusion or ascites. * Presence of other malignancies that have not been cured. * History of significant psychiatric disorders that impede understanding of informed consent and compliance with the study protocol. * Presence of other serious illnesses that may pose significant risks or affect radiation therapy. * Women who are pregnant, breastfeeding, or with plans for childbearing during the study. * Any other reasons deemed by the investigator to make the subject unsuitable for participation in the study.
