• European RCC academic physicians have gathered into a European initiative the CARE group. Systemic therapy for RCC relies on two classes of agents: anti-angiogenic targeted therapy (Vascular endothelial growth factor Tyrosine Kinase Inhibitor- VEGFR TKI) and immune checkpoint inhibitor (ICI), targeting either PD-1/PD-L1 axis or CTLA-4. Combination therapy is standard of care (SOC) for clear cell RCC in all guidelines with either ICI-ICI or ICI-VEGFR TKI. However, no head-to-head comparison have been performed between the two approaches and patients are treated based on physician decision without clinical or biomarker factors to guide treatment selection. PD-L1 staining is, to date, the biomarker that has demonstrated its ability to enrich for overall survival benefit favoring ICI-ICI strategy in PDL1(+) and ICI-VEGFR TKI in PDL1(-) patients.CARE1 PCT is a prospective randomize phase III study, in first line setting for patients with metastatic clear cell RCC comparing ICI-ICI vs ICI-VEGFR TKI approaches stratified on PD-L1 by local determination. Primary endpoint is overall survival (OS). The trial will enroll 1250 patients over 3 years across eight European countries that are part of the CARE consortium. Study Sponsor is Gustave Roussy institute within the GETUG network for France, co-sponsor is developed through main academic networks (eg. SOGUG in Spain) and main institutions across Europe (eg. Cancer Core Europe CCE). Study design has been develop to demonstrate that ICI-ICI is superior to ICI-VEGFR TKI in prolonging OS for PDL1(+) patients and that ICI-VEGFR TKI is superior to ICI-ICI in prolonging OS for PDL1(-) patients. CARE1 PCT has been designed and will be conducted with patient advocacy group representatives (ARTuR and IKCC) input. CARE1 is an academic phase III study designed to define the optimal combination using a pragmatic routinely implementable biomarker. Therefore
• CARE1 will inform practice and has the potential to change treatment guidelines. Taken all together
• CARE1 is a unique opportunity to build a large-scale platform to define new biomarker based therapy guidelines as well as to investigate quality of life, patient reported outcome and Health-Economic in front line setting, as well as pathological and blood biobank collection for further translational work.
