A Phase 1/2 Open-label Study of Pembrolizumab Combined With PNT-2002 Radioligand Therapy in Patients With Metastatic Renal Cell Carcinoma
This is a multi-center, single arm open label phase 1b/2 study of pembrolizumab in combination with 177Lu-PNT2002 (also known as 177Lu-PSMA I\&T) radiopharmaceutical therapy in patients with metastatic clear cell renal cell carcinoma (RCC) who have progressed after prior treatment with anti-programmed cell death protein 1 (PD1) or PD-L1 immune-checkpoint inhibitors (ICIs). The study comprises 2 phases: an open-label Phase 1b dose escalation portion followed by a Phase 2 dose expansion portion. Investigators hypothesize that pembrolizumab in combination with 177Lu-PNT2002 in in patients with metastatic clear cell RCC at a biologically active dose will result in tolerable safety profile and it will lead to improved radiological objective responses in patients who have progressed after prior treatment with standard anti-PD1 or anti- Programmed Cell Death Ligand 1 (PDL1) immune-checkpoint inhibitor containing regimen when compared to historic controls. Patients in both phases will have prostate-specific membrane antigen (PSMA), positron emission tomography (PET) imaging with the radiotracer (F-18)-DCFPyl, to help detect any spread of the cancer.
