A Phase 2 interventional study of axitinib plus toripalimab and SABR in Oligometastatic Clear Cell Renal Cell Carcinoma, sponsored by Hebei Medical University Fourth Hospital. Recruiting at 1 site in China. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-08-04.
Sponsored by Hebei Medical University Fourth Hospital · Phase 2, Interventional, and Treatment
This is a phase II clinical trial testing whether a combination of stereotactic ablative radiotherapy (SABR), axitinib, and toripalimab is effective and safe for treating oligometastatic clear cell renal cell carcinoma (a type of kidney cancer that has spread to 5 or fewer sites).
In this study, all metastatic tumors will be treated with SABR - a precise, high-dose radiation therapy delivered in 5 sessions. At the same time, participants will receive axitinib (an oral targeted cancer drug) twice daily, and toripalimab (an intravenous immunotherapy) every 3 weeks for up to 2 years.
The study will enroll 48 participants. The main goal is to measure the objective response rate - the proportion of patients whose tumors shrink or disappear after treatment. Researchers will also track how long patients live without their cancer worsening, overall survival, and any side effects from the treatment.
Participants will have regular imaging scans, blood tests, and quality-of-life assessments throughout the treatment and follow-up period.
2,037 studies on the registry are indexed under Carcinoma, Renal Cell; 395 are open to participants now.
This study's planned enrollment of 48 is above the median of 43 across 1,564 interventional studies indexed under Carcinoma, Renal Cell.

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

All participants receive stereotactic ablative radiotherapy (SABR) to all measurable metastatic lesions (≥7 Gy per fraction, 5 fractions, BED₃ ≥ 115 Gy), concurrent axitinib (5 mg orally twice daily) and toripalimab (240 mg intravenously every 3 weeks for up to 35 cycles). Axitinib is continued until disease progression, intolerable toxicity, or withdrawal of consent. For oligoprogressive lesions (≤5 lesions), additional SABR may be administered at the investigator's discretion.
Drug: axitinib plus toripalimab · Radiation: SABR
Drug pages: Axitinib · Toripalimab
Axitinib 5 mg administered orally twice daily continuously, combined with toripalimab 240 mg administered intravenously every 3 weeks for up to 35 cycles (approximately 2 years).
All participants receive stereotactic ablative radiotherapy (SABR) to all measurable metastatic lesions, delivering ≥7 Gy per fraction in 5 fractions, achieving a biologically equivalent dose (BED₃) ≥ 115 Gy based on α/β = 3 Gy. For lesions adjacent to organs at risk, partial-SABR is permitted. If SABR or partial-SABR is infeasible, moderately hypofractionated radiotherapy (MHFRT) with curative intent may be substituted at the discretion of the radiation oncologist.

Local Control Rate
Time frame: From enrollment to the end of treatment (up to approximately 2 years)
Disease Control Rate (DCR)
Time frame: From enrollment to the end of treatment (up to approximately 2 years)
Progression-Free Survival (PFS)

Start is estimated for Aug 2026; primary completion for Dec 2027, 16 months later.
Of 183 non-industry phase 2 interventional studies under Carcinoma, Renal Cell, half reached primary completion within 67 months of starting (the median), counting those still running; a quarter within 41 and three quarters within 98. This study's planned 16 months is below that.
Counting every sponsor, half of 230 studies reached it within 58 months; a quarter within 33 and three quarters within 94.
