Trial Summary

What is the purpose of this trial?

PART 1: The primary objective of this study is to identify the maximum tolerated dose (MTD) of MK-3795, formerly called PT2385 and/or the recommended Phase 2 dose (RP2D) of MK-3795 in patients with advanced clear cell renal cell carcinoma (ccRCC). PART 2: The primary objective of this study is to identify the MTD of MK-3795 up to the RP2D, in combination with nivolumab, in patients with advanced ccRCC.As of Amendment 09 (29 Mar 2024), participants with advanced ccRCC will transition from MK-3795 to belzutifan (MK-6482) in combination with nivolumab or belzutifan alone. PART 3: The primary objective of this study is to identify the MTD of MK-3795 up to the RP2D, in combination with cabozantinib tablets, in patients with advanced ccRCC.

Interventions

Cabozantinib (Tyrosine Kinase Inhibitor)
Nivolumab (Checkpoint Inhibitor)
PT2385/MK-3795 (HIF-2alpha Inhibitor)

Trial OverviewThe study tests different doses of MK-3795 alone and in combination with Nivolumab or Cabozantinib to find the highest dose patients can tolerate without severe side effects (MTD) and recommend for future studies (RP2D). It's divided into three parts: testing MK-3795 alone; then with Nivolumab; and finally with Cabozantinib.

Participant Groups

3Treatment groups

Experimental Treatment

Group I: Part 3: MK-3795 + CabozantinibExperimental Treatment2 Interventions

Participants with advanced ccRCC in the expansion phase receive the RP2D of MK-3795 in combination with cabozantinib 20mg up to 60mg orally QD for up to approximately 1 year (12 cycles; each cycle length = 28 days) or until unequivocal progression or treatment discontinuation, whichever occurs later.

Group II: Part 2: MK-3795 + Nivolumab + BelzutifanExperimental Treatment3 Interventions

Participants with advanced ccRCC in the expansion phase receive the RP2D of MK-3795 orally in combination with nivolumab 240mg by IV infusion over \~60 minutes every 2 weeks for up to \~1 year (12 cycles; each cycle length = 28 days) or until unequivocal progression or treatment discontinuation, whichever occurs later. As per Amendment 09 (29 March 2024), participants will not receive MK-3795. Participants receive nivolumab 240mg by IV infusion over \~60 minutes every 2 weeks in combination with belzutifan 120 mg once daily (QD) for up to \~1 year (12 cycles; each cycle length = 28 days) or until unequivocal progression or treatment discontinuation, whichever occurs later. If participants experience an adverse event, then nivolumab will be discontinued and participants will continue to receive belzutifan 120 mg QD alone for up to \~1 year (12 cycles; each cycle length = 28 days) or until unequivocal progression or treatment discontinuation, whichever occurs later.

Group III: Part 1: MK-3795Experimental Treatment1 Intervention

Participants with advanced ccRCC receive MK-3795 at an initial dose level of 100mg orally, twice daily (BID) up to approximately 3 weeks. Dose levels will be escalated to identify the maximum tolerated dose (MTD) and/or Recommended Phase 2 Dose (RP2D) for MK-3795. Each escalated dose will be continued for up to approximately 3 weeks before escalating a dose again until a dose limiting toxicity (DLT) is experienced. Thereafter, participants receive RP2D dose of MK-3795 for up to 2 cycles (each cycle length = 28 days) for up to approximately 1 year. Participants may continue to receive MK-3795 beyond 1 year at the discretion of the Sponsor.
