Atezolizumab Plus CArboplatin Plus Nab-paclitaxel

Summary

Primary objective: To provide preliminary evidence on the efficacy of atezolizumab plus carboplatin plus paclitaxel as first-line therapy in metastatic triple-negative PD-L1 positive breast cancer patients as evaluated by % 2years OS. Secondary objective: * To provide preliminary evidence on the efficacy of atezolizumab plus carboplatin plus paclitaxel as first-line therapy in metastatic triple-negative PD-L1 positive breast cancer patients in terms of % OS at 2.5 years * To provide preliminary evidence on the efficacy of atezolizumab plus carboplatin plus paclitaxel as first-line therapy in metastatic triple-negative PD-L1 positive breast cancer patients in terms of % OS at 2 years in hormonal receptor (HR) between 1% and 10% * To provide preliminary evidence on the efficacy of atezolizumab plus carboplatin plus paclitaxel as first-line therapy in metastatic triple-negative PD-L1 positive breast cancer patients in terms of post-progression survival * To assess the activity of atezolizumab plus carboplatin plus paclitaxel as first-line therapy in metastatic triple-negative PD-L1 positive breast cancer patients in terms of ORR, and time to treatment failure * To assess the safety of atezolizumab plus carboplatin plus paclitaxel as first-line therapy in metastatic triple-negative PD-L1 positive breast cancer patients Exploratory Objectives: Exploratory objectives will be focused on the assessment of both tumor-centered characteristics through the NGS analysis of circulating tumor DNA (ctDNA) and immune-centric features through the evaluation of a multiparametric Cancer agnostic circuLating ImmunOsignature (CLIO): * To assess the association between patients' characteristics, treatment activity, efficacy and safety and through a CLIO in metastatic triple-negative breast cancer patients receiving atezolizumab plus carboplatin plus paclitaxel as first-line therapy * To explore the association between the CLIO and treatment activity, efficacy and safety * To explore the dynamics of circulating tumor DNA (ctDNA) levels and detectable aberrations with respect to treatment activity and efficacy Concomitant timepoints will not be used for cross-validations between the two methodologies.
