Can a blast of radiation make immunotherapy work better against kidney cancer?
NCT ID NCT02306954
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This phase 2 trial is testing whether adding stereotactic body radiation therapy (SBRT) to high-dose Interleukin-2 (IL-2) can improve response rates in people with metastatic renal cell carcinoma. All participants receive IL-2, and half also get two doses of SBRT to a few tumor spots before starting IL-2. The study aims to see if the combination shrinks more tumors than IL-2 alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- high-dose Interleukin-2 (IL-2) with or without stereotactic body radiation therapy (SBRT)
- What this could lead to
- If adding SBRT boosts the response rate, this could become a new treatment option for metastatic kidney cancer.
- What could go wrong
- This is a mid-stage trial with only 84 participants, so results may not apply broadly. High-dose IL-2 can cause serious side effects, and the added radiation may not improve outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Histological confirmation of predominant conventional (clear cell) renal cancer * Patients must be ≥ 18 years of age * Tumors amenable to SBRT in lungs (central locations preferred), mediastinum, chest wall, bones with a soft tissue component (other than long bones), or liver, liver hilum and associated lymph nodes (inclusive of immediately adjacent masses), 1 - 3 foci; no minimum size, but none greater than 7 cm. Patients may have other metastases but only a maximum of 3 will be treated * Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 * Women of childbearing potential must have a negative serum or urine pregnancy test within 72 hours prior to the start of protocol treatment. In addition, women of childbearing potential as well as male patients must agree to take appropriate precautions to avoid pregnancy * Patients must agree to participate in the Prometheus IL-2 patient registry (PROCLAIM registry) * Patients must sign a study-specific consent form Exclusion Criteria: * No metastatic site amenable to SBRT * Patients with brain metastases not candidates for radiosurgery alone * Previous radiation to sites proposed for SBRT * Patients with active systemic, pulmonary, or pericardial infection * Pregnant or lactating women, as treatment involves unforeseeable risks to the embryo or fetus * Evidence of ischemia on exercise tolerance test, stress thallium study, or baseline EKG * Clinically significant underlying pulmonary disease as measured by pulmonary function tests * Blood tests within protocol-specified range * Need for chronic steroids
