Treatment Pause Versus Treatment Continuation in IMDC Good or Intermediate Risk With Only One Adverse Prognostic Factor in mRCC Patients With an Objective Response at 12 Months of Treatment With PD1/ PDL1 ICIs + VEGFR-Tyrosine Kinase Inhibitors — SPICI  

Metastatic Renal Cell Carcinoma Clinical Trial

Official title: SPICI: Strategic Treatment Pause of First-line Immune Check Point Inhibitor + VEGFR-Tyrosine Kinase Inhibitor in Good or Only One Adverse Prognostic Factor in Intermediate Risk Metastatic Renal Cell Carcinoma (mRCC) With an Objective Response: a Randomised, Non-inferiority Phase III Study

Status Recruiting

Clinical Trial Summary

The purpose of this study is to demonstrate the non-inferiority of treatment pause versus treatment continuation in good or intermediate risk with only one adverse prognostic factor as per IMDC mRCC patients with a confirmed objective response at 12 months of treatment with PD-1/PD-L1 ICI plus VEGFR-TKI.

Tolerance and quality of life of treatment pause with PD-1/PD-L1 ICI + VEGFR-TKI compared to treatment continuation will be reported. In France, its impact on healthcare resource utilization will also be assessed.

Clinical Trial Description

Although multiple combinations therapies in particular PD-1/PD-L1 immune-checkpoint inhibitors (PD-1/PD-L1 ICIs) in combination with vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) are approved and have improved patient's outcomes with mRCC, they are maintained until disease progression and treatment pause after an objective response has not been fully explored [5-7]. The good-risk population is characterised by prolonged survival therefore a treatment pause in this population could impact the quality of life, safety and total cost of care, without impacting outcome. As well, intermediate risk population group is heterogeneous, while the one's with only one adverse prognostic factor seems to be closed to the outcome of good risk population [11-15]. As the purpose of the study is to target patients with an objective response, there is already a selection of patients with a better outcome.

Patient will be randomised after 12 months of treatment with PD-1/PD-L1 ICI plus VEGFR-TKI (treatment pause versus treatment continuation) and follow every 3 months for a period of 12 months following by 12 additional months for survival follow-up. ;
