Clinical Trial Summary

This study (phase I clinical trial and expansion cohorts) will evaluate safety and efficacy of combination of atezolizumab and tiragolumab, with concomitant or sequential SBRT for four oligometastatic cancer cohorts. This study will allow to developpe one or several randomized Phase II clinical trials for the more promising indications

Description:

This study will be composed of 2 stepms. First step will be a phase I with the aim to establish the recommended safety scheme of administration (concomitant or sequential) of tiragolumab + atezolizumab + SBRT. The phase I will enrolled only patients from the cohort 1 (metastatic non-small cell lung cancer). The second step will be an expansion cohorts phase at the recommended scheme of administration. The second step will enrolled patients from 4 different cohorts (metastatic non-small cell lung cancer, metastatic bladder cancer, metastatic renal cell carcinoma, metastatic head and neck carcinoma).

Secondary	Expansion cohort : The long term safety of SBRT, atezolizumab and tiragolumab antibodies combination	Evaluation by analysis of AAE. Will be evaluated with acute and late adverse events (AAEs) according to CTCAE 5.0 Treatment safety evaluation will be based on adverse event (AE) occurrence, the use of concomitant treatments, changes occuring in the course of treatment, observed during physical examination, in the vital signs (arterial pressure, pulse and body temperature), in electrocardiogram (ECG) and biological and clinical examinations (biochemistry, haematology).	Throughout the treatment period (24 months)
Secondary	Expansion cohort : overall survival (OS) following SBRT, atezolizumab and tiragolumab combination	Evaluation by analysis of Overall survival. Overall survival is defined as the time from inclusion to death to any cause	Until the patient dies
Secondary	Expansion cohort : Overall Response rate (ORR) and Non progression rate (NPR) following SBRT, atezolizumab and tiragolumab combination	Evaluation by analysis of ORR. ORR is evaluated from the first two evaluation scanner images carried out at 8-9 and 16-18 weeks after time from inclusion (CT-scan forecast after the 3rd and the 6th cure) as determined by the investigator according to RECIST v1.1 and iRECIST.	18 weeks after inclusion
