About this study

The goal of IMMUNOLIFE2 is to overcome primary resistance to immune checkpoint inhibitors (ICIs), such as pembrolizumab or nivolumab used alone or in combination with chemotherapy, observed in patients with advanced non-small cell lung cancer (NSCLC) following antibiotic exposure, which induces intestinal dysbiosis. The reintroduction of immunotherapy with Cemiplimab, combined with oral pooled fecal microbiotherapy (MaaT033), aims to restore gut microbiota and potentially reverse resistance to ICIs. The main objective is to determine whether the combination of MaaT033 and Cemiplimab provides a superior disease control rate compared to the current best investigator's choice as comparator. Patients will be randomized to receive either: * Experimental arm: MaaT033 administered orally for one week prior to each cycle of Cemiplimab, which will be given in hospital care every 3 weeks for 6 months, followed by Cemiplimab alone thereafter; * Control arm: Best investigator's choice
