Summary

This trial aims to shrink tumor thrombus to reduce surgical complications and improve patient health outcomes, with the hope of providing better long-term results.

Who is the study for?
Adults with clear cell renal cell carcinoma and a tumor thrombus in the inferior vena cava who are candidates for surgery. They must have good performance status, controlled blood pressure, no major surgeries or radiation therapy within specific time frames before enrollment, and not be on certain medications that affect immune response or blood clotting.
What is being tested?
The trial is testing if Pembrolizumab combined with Axitinib can reduce the size of kidney cancer-related blood clots in the vein before surgery. The goal is to see if this pre-surgery treatment leads to fewer surgical complications and better long-term health outcomes like survival without cancer progression.
What are the potential side effects?
Possible side effects include high blood pressure, fatigue, liver enzyme changes, thyroid dysfunction, diarrhea, loss of appetite, hand-foot syndrome (redness and pain on palms or soles), immune-related reactions such as inflammation in organs like lungs (pneumonitis) or intestines.

Experimental Treatment
Group I: Combination Pembrolizumab and AxitinibExperimental Treatment2 Interventions
Neoadjuvant therapy with the combination of Pembrolizumab and Axitinib will be given for eligible RCC patients with an IVC TT for a total of 12 weeks. Patients will then undergo imaging with a contrast enhanced, diffusion weighted imaging MRI of the abdomen to evaluate the IVC TT response. A CT chest will also be done to ensure there is no progression of disease. Patients can undergo definitive surgery per treating Urologist within 2 weeks (+/- 7 days) after end of treatment scan.
