Official title: A Phase 3, Randomized, Double-blind, Study of Belzutifan + Zanzalintinib Versus Belzutifan + Placebo in Participants With Advanced RCC Who Have Progressed on or After Both PD-1/L1 and VEGF-TKI Therapies in Sequence or in Combination (LITESPARK-034)

Run by Merck Sharp & Dohme LLC · NCT07489495 · Data updated 2026-11-12

This trial tests whether adding the targeted drug zanzalintinib to belzutifan helps people with advanced renal cell carcinoma live longer and delay tumor growth compared with belzutifan plus placebo.

Is this trial a fit for you?

Likely a good fit

Ideal candidates have unresectable, advanced clear-cell renal cell carcinoma with measurable disease, have had no more than three prior systemic regimens (including only one prior PD-1/PD-L1 therapy), and meet standard safety criteria for investigational targeted therapies.

Probably not a fit

Patients without a clear-cell component, those who require chronic supplemental oxygen, have recent significant cardiovascular disease, or many prior lines of therapy may be unlikely to benefit or may be excluded from the study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized Phase 3 trial compares belzutifan combined with zanzalintinib to belzutifan plus placebo in people with unresectable, advanced renal cell carcinoma that has a clear-cell component. Eligible participants must have measurable disease and may have received up to three prior systemic therapies, including no more than one prior PD-1/PD-L1 inhibitor. The co-primary goals are to compare overall survival and time without disease worsening (progression-free survival) between the two treatment arms. The multicenter international study is sponsored by Merck Sharp & Dohme with collaboration from Exelixis and is open at sites in countries including Argentina and Australia.

Why it matters

Potential benefit: If successful, adding zanzalintinib to belzutifan could help people with advanced RCC live longer and keep their cancer under control for a longer time.

How similar studies have gone: Belzutifan has shown activity in RCC and combinations of targeted agents have improved outcomes in some prior RCC settings, but combining belzutifan with zanzalintinib is a new approach being tested in this Phase 3 trial.
