Study Summary

This trial tests 2 drugs to treat kidney cancer in people aged 18+. Participants take pills and get injections, have tests and scans. Follow-up visits and scans are done for up to 6 years.

Who is the study for?
Adults with advanced kidney cancer, either clear cell renal cell carcinoma (ccRCC) after checkpoint inhibitor therapy and possibly VEGF antagonist treatment, or papillary renal cell carcinoma (pRCC), which may be untreated. Participants need at least one measurable tumor lesion, good physical condition, adequate blood counts and organ function. They must agree to use effective contraception and not breastfeed during the trial.Check my eligibility
What is being tested?
The trial is testing a combination of two drugs: Sasanlimab (an injection) given once each cycle, and Palbociclib (a pill) taken daily for 21 days in each 28-day cycle. The study aims to evaluate their effectiveness in treating kidney cancers over cycles lasting up to two years with follow-ups extending up to six years.See study design
What are the potential side effects?
Potential side effects include reactions at the injection site for Sasanlimab, liver issues from both drugs, fatigue, nausea or other digestive problems from Palbociclib. Blood count changes could also occur. Side effects can vary between individuals.

Answered by AI

What outcomes is this investigation seeking to accomplish?

"The primary goal of this 28-day clinical trial is to assess the objective response rate (ORR) of the combination. Additionally, progression-free survival (PFS), safety of the combination and overall survival (OS) will be monitored as secondary outcomes. These data points will be gathered through regular imaging scans every 8 (+/-1) weeks for 32 weeks followed by 12 (+/- 1) week intervals until either disease progression or 6 years after enrollment are recorded. Toxicities or adverse events must also be documented from Day 1 up to 90 days following intervention administration where applicable - only serious side effects related to study interventions reported beyond that window."
