Phase 3 Study Comparing Belzutifan and Zanzalintinib Versus Cabozantinib in Adults With Advanced Recurrent Kidney Cancer After Prior Adjuvant Anti-PD-1L1 Therapy

What this Trial Is About

Researchers are investigating new treatments for advanced renal cell carcinoma RCC that has returned after prior therapy. The study aims to find out if the combination of belzutifan and zanzalintinib can help people with recurrent advanced RCC live longer without their cancer worsening compared to the drug cabozantinib. This is a phase 3 randomized trial evaluating these treatments in participants who have experienced recurrence during or after prior anti-PD-1L1 therapy. Participants are randomly assigned to receive either belzutifan plus zanzalintinib taken orally once daily or cabozantinib taken orally once daily. They continue their assigned treatment until certain reasons require stopping the study intervention. The study compares the effects of these treatments on cancer progression and survival among people with advanced RCC who have had disease recurrence after adjuvant therapy. During the study, participants will be regularly monitored for progression-free survival and overall survival for up to about 73 months. Researchers will also assess tumor response, duration of response, adverse events, and quality of life using questionnaires over approximately 25 months. The study involves ongoing evaluations to understand how these treatments affect symptoms, functioning, and overall health during long-term follow-up.
