Renal cell carcinoma is the most common kidney cancer in adults, accounting for about 90% of kidney cancers. Treatment depends on stage: early-stage disease is often cured with surgery, while advanced disease is treated with combinations of immunotherapy, targeted drugs, and sometimes surgery. Five-year survival for metastatic disease has improved dramatically over the past decade.

What's actually going on in research

Trials are testing new combinations of checkpoint inhibitors with drugs targeting blood vessel growth, newer TKIs that block cancer cell signals, and CAR-T cell approaches adapted from blood cancer treatments. Researchers are also studying whether treating small kidney tumors with ablation can match surgery outcomes, and testing adjuvant therapy after surgery to prevent recurrence.

Immunotherapy combinations

Pairing checkpoint inhibitors like nivolumab with drugs that starve tumors of blood supply has become standard for metastatic disease. Trials are now testing triple combinations and looking for biomarkers that predict which patients respond best.

HIF-2α inhibitors

A new class of drugs blocks a protein that helps kidney cancer cells survive low oxygen. Belzutifan was FDA-approved in 2021 for von Hippel-Lindau disease and is now being tested in broader kidney cancer populations.

CAR-T for solid tumors

Researchers are engineering immune cells to attack CAIX, a protein abundant on kidney cancer cells. Early trials are testing whether these modified cells can work against solid tumors as they do in blood cancers.

What to know before you search

Eligibility typically depends on disease stage, prior treatments, kidney function, type of renal cell carcinoma, and presence of metastases.

What types of trials are currently open

  • Combination therapy trialsTesting pairs or triplets of immunotherapy and targeted drugs to find the most effective regimen with tolerable side effects for metastatic disease.
  • Adjuvant trialsTesting whether giving immunotherapy or targeted drugs after surgery prevents cancer from coming back in people at high risk of recurrence.
  • Surgery vs. ablation trialsComparing outcomes when small kidney tumors are destroyed with heat or cold rather than surgically removed.
  • Biomarker studiesLooking for genetic or molecular markers that predict which treatments will work best for each person's cancer.
  • Quality of life studiesFollowing people to understand how treatments affect daily function, fatigue, and long-term health.
