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

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.
