Kidney cancer often presents no symptoms until it's found on imaging for another reason. Surgery remains the main treatment for early disease, while advanced kidney cancer is now treated with combinations of immunotherapy drugs and targeted therapies that have turned a once-grim prognosis into a manageable chronic condition for many people.

What's actually going on in research

Trials are testing new immunotherapy combinations, antibody-drug conjugates that deliver chemotherapy directly to cancer cells, drugs targeting HIF-2α that block the fuel supply to tumors, and CAR-T cell therapies adapted from blood cancer treatment. Researchers are also studying which biomarkers predict response to treatment and whether targeted drugs can prevent recurrence after surgery.

HIF-2α inhibitors

Belzutifan blocks a protein that kidney cancer cells use to survive low-oxygen conditions. FDA-approved for von Hippel-Lindau disease and advanced kidney cancer, it's now being tested in earlier disease and combinations.

Antibody-drug conjugates

These molecules deliver chemotherapy directly to cancer cells by targeting proteins on their surface. Several are in trials for kidney cancer that has stopped responding to standard treatments.

Adjuvant therapy

Studies are testing whether giving immunotherapy or targeted drugs after surgery prevents cancer from returning. The goal is to identify which patients benefit most from additional treatment.

What to know before you search

Eligibility usually depends on kidney cancer subtype, disease stage, prior treatments received, and kidney function level.

What types of trials are currently open

  • Combination therapy trialsTesting pairs or triplets of immunotherapy drugs and targeted therapies, often comparing new combinations to current standards. These dominate kidney cancer research.
  • Adjuvant trialsTesting whether giving treatment after surgery prevents kidney cancer from coming back in people at high risk of recurrence.
  • Biomarker trialsStudying tumor tissue and blood to identify which patients will respond to which treatments, aiming to personalize therapy choices.
  • Rare subtype trialsTesting treatments specifically for less common forms like papillary or chromophobe kidney cancer, which may need different approaches than clear cell.
  • Resistance trialsTesting new drugs for people whose kidney cancer has stopped responding to immunotherapy or targeted therapies.
