Oral Pooled Fecal Microbiotherapy (MaaT033) Concomitant to Cemiplimab Versus Best Investigator's Choice in Patients With Resistance to Treatment Due to Antibiotics Uptake With Advanced Non-small Cell Lung Cancer
brief summary
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
detailed description
IMMUNOLIFE2 is a randomized Phase II clinical trial multicenter aiming at circumventing primary resistance to ICI observed in patients with advanced NSCLC following ATB uptake in the harmful window using FMT strategy (oral pooled fecal microbiotherapy MaaT033) concomitant to CB. Hence the IMMUNOLIFE2 trial described here is exploring the possibility of an improvement of DCR to CB in patients with ICI resistance due to ATB-induced gut dysbiosis. This will be an outstanding opportunity to explore a therapeutic strategy to surpass ATB mediated resistance but for any cause of intestinal dysbiosis that compromise anti-PD1-based therapy efficacy.
