MSD MK 6482-011

Genitourinary cancer 

Inclusion Criteria:

• Unresectable, locally advanced or metastatic clear cell renal cell carcinoma (RCC).
• Disease progression on or after an antiPD-1/L1 therapy as either first or second-line treatment for locally advanced/metastatic RCC or as adjuvant treatment or neoadjuvant/adjuvant with progression on or within 6 months of last dose.
• Received no more than 2 prior systemic regimens including: one anti-PD-1/L1 containing adjuvant or neoadjuvant/adjuvant regimens with progression on or within 6 months from the last dose of that regimen OR one or 2 regimens for locoregional/advanced disease
• Received only 1 prior antiPD-1/L1 therapy for adjuvant, neoadjuvant/adjuvant or locally advanced/metastatic RCC.
• Adequate organ function.

Exclusion Criteria:

• Known central nervous system (CNS) metastases and/or carcinomatous meningitis.
• Clinically significant cardiac disease within 6 months of first dose of study intervention.
• Prolongation of QTc interval to >480 ms.
• Symptomatic pleural effusion (e.g.,cough, dyspnea, pleuritic chest pain) that is not clinically stable.
• Pre-existing ≥Grade 3 gastrointestinal or nongastrointestinal fistula.
• Moderate to severe hepatic impairment.
• History of significant bleeding within 3 months before randomization.
• History of solid organ transplantation.
• Prior treatment with belzutifan or another hypoxia-inducible factor (HIF)-2α inhibitor.
• Prior treatment with lenvatinib.
• Prior treatment with cabozantinib.

This study will compare the efficacy and safety of belzutifan + lenvatinib versus cabozantinib in participants with advanced renal cell carcinoma (RCC) with clear cell component after prior therapy.

The primary hypothesis is that belzutifan + lenvatinib is superior to cabozantinib in terms of progression-free survival or overall survival.
