Design outcomes

Primary

MeasureTime frame
Main Objective: To assess whether the safety of a 23-week treatment with MaaT013, combined with ipilimumab+nivolumab, is different from that of ipilimumab+nivolumab+placebo in patients with melanoma naïve to Ipilimumab and anti-PD1;Secondary Objective: - To assess whether a 23-week treatment with MaaT013, combined with Ipilimumab and Nivolumab, is more efficient than Ipilimumab and Nivolumab + placebo - To assess changes in the tumor microenvironment in patients who have received MaaT013 and placebo ; - Changes in plasma levels of proteins or metabolites that play a role in immune activity against cancer and/or are associated with gut microbiome composition, pre and post MaaT013 or placebo -To assess peripheral blood T cell subpopulations that have been identified as associated with gut microbiome composition or response to anti CTLA-4 and anti PD1 in previous human studies; - To assess the evolution of gut microbial members and metabolites; - To assess, on an open basis, the efficacy and safety of MaaT013 combined with Nivolumab in a subset of patients who failed to respond to placebo+Ipilimumab and Nivolumab in the randomized part of the trial. ;Primary end point(s): Safety will be measured by the occurrence of Grade 3 and grade 4 adverse events (AE), as graded by the CTCAE v 5.0 during the 27 weeks of the trial. ;Timepoint(s) of evaluation of this end point: Week 27

Secondary

MeasureTime frame
Secondary end point(s): - Efficacy will be assessed by the best overall response rate, rated by immunological Response Evaluation Criteria in Solid Tumors (iRECIST; 19) in the experimental and control arms and among them, within the subgroup of patients who carried the unfavourable baseline microbiota. - Changes in the tumor micro environment (TME) pre and post MaaT013 or placebo - Changes in plasma levels of proteins or metabolites that play a role in immune activity against cancer and/or are associated with gut microbiome composition, pre and post MaaT013 or placebo - Changes in peripheral blood immune cell subpopulations pre and post MaaT013 or placebo - Changes in gut microbiome and metabolites pre and post MaaT013 or placebo - Overall response rate, either complete or partial, rated by RECIST in patients with a stable disease or disease progression who received placebo and subsequently, MaaT013, in an open-label basis. - Progression-free survival at week 15, 27, 51 - Overall survival at week 15, 27, 51 - Best overall response rate, either complete or partial, rated by RECIST v1.1. and PET scan - Disease control rate (complete or partial response or stable disease) - Pseudo progression rate ;Timepoint(s) of evaluation of this end point: until Week 51
