Recruiting now · Phase 2

Conditions studied: Renal Cell Carcinoma, Radiotherapy, Immune Checkpoint Inhibitor

In brief

The objective of this single-center clinical study was to evaluate the disease control rate(DCR) and safety of multimodal radiotherapy in the treatment of patients with renal cell carcinoma (RCC) progressed after prior immunotherapy.

Subject's previous treatment: Disease progression or intolerance following prior treatment with 1-2 systemic therapies (at least one regimen containing immune checkpoint inhibitors, including combined VEGFR-TKI drugs), And patients who have progressed within 12 months of prior immunoadjuvant or neoadjuvant therapy; According to the evaluation of attending physicians and professional radiotherapy doctors, it meets the standard of radiotherapy.
Patients can tolerate sequential immunotherapy while receiving radiation therapy.

Subjects have fully understood and voluntarily signed an informed Consent form (ICF).
ECOG 0-1 points.
Major organs are functioning well.
Willing and able to comply with study plan visits, treatment laboratory tests, sample retention, and other procedures.
Fertile women must voluntarily use a highly effective contraceptive method (e.g., oral, injectable or implantable, barrier method, spermicide and condom, or intrauterine device) from the study period to ≥120 days after the last dose and have negative urine or serum pregnancy test results ≤7 days prior to enrolment.
Male patients who are not sterilized must voluntarily use highly effective contraception during the study period until ≥120 days after the last dose.

You may not qualify if…

A history of malignancies other than the disease studied within the past 5 years, other than malignancies that are expected to be cured with treatment (including but not limited to adequately treated thyroid cancer, cervical carcinoma in situ, basal or squamous cell skin cancer, or breast ductal carcinoma in situ treated with radical surgery).
Systemic treatment with other antitumor agents, including targeted agents, immunotherapy agents and their combination regimens (eligible for inclusion after 5 half-lives), local antitumor therapy, or clinical investigational drug or device therapy, was administered 4 weeks prior to the first study.
Previous history of radiation therapy at any site or in any mode.
Had major surgery (as judged by the investigator) within 4 weeks prior to the first trial or was convalescing.
A history of severe drug allergy, including but not limited to antibody drugs.
Patients with contraindications to restart immunotherapy.
A known history of allogeneic organ transplantation and allogeneic hematopoietic stem cell transplantation may require long-term adrenal corticosteroid therapy.
Patients with thyroid, suprarenal, or hypopituitarism that can be controlled with hormone replacement therapy alone, type 1 diabetes, and psoriasis or vitiligo that do not require systemic treatment are eligible to participate in this study.
Toxicity did not resolve after previous antitumor therapy, i.e. regression to baseline, prescribed grade 0 to 1 (except alopecia) as defined in NCI-CTCAE 5.0, or to the levels specified in the inclusion/exclusion criteria. Irreversible toxicity (such as hearing loss) that could reasonably be expected not to be aggravated by the drug under study could be included in this study.
Have central nervous system metastases and/or cancerous meningitis.
A known history of clinically significant liver disease.
Accompanied by uncontrolled third space effusion requiring repeated drainage, such as pleural effusion, ascites, pericardial effusion, etc.
In the first study, systemic corticosteroids or other immunosuppressive drugs were administered within 14 days prior to medication.
Patients with any severe or uncontrolled disease.
Have or have a suspected presence of active autoimmune diseases, including but not limited to systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, etc.
Renal failure requires hemodialysis or peritoneal dialysis.
A history of immunodeficiency, including HIV positive or other acquired, congenital immunodeficiency diseases, or a history of organ transplantation.
History of live attenuated vaccine vaccination within 4 weeks prior to administration or expected live attenuated vaccine vaccination during the study period was studied for the first time.
People who have a history of psychotropic substance abuse and cannot abstain or have a history of mental disorders.
Pregnant or lactating women.
Other severe, acute, or chronic medical or psychiatric conditions or laboratory abnormalities, as determined by the investigator, that may increase the risks associated with study participation or that may interfere with the interpretation of the study results.
