Brief Summary

Immunotherapy has recently become a main-stream treatment option in cancer care, with improved clinical outcomes in many malignancies, especially that of lung cancer. The long-term benefits of this treatment however are limited. There is therefore a critical need to distinguish predictive biomarkers of response from those of resistance, and to develop synergistic strategies for improved therapeutic response. Strong emerging evidence indicates that the gut microbiome has the ability to influence response to immunotherapy. Unlike tumor genomics, the gut microbiome is modifiable, and thus its modulation to enhance response to immunotherapy is an attractive therapeutic strategy. Working hypothesis: Fecal Microbiota Transplant (FMT) treatment in conjunction with standard (chemo-)immunotherapy as a first-line treatment for metastatic lung cancer enhances disease control rate. The main objective of this study is to evaluate the safety and efficacy of Fecal Microbiota Transplant (FMT) in altering response to immunotherapy in patients with metastatic lung cancer. The overall goal is to determine microbiome compositional and gene-content changes in patients who respond more efficiently to immunotherapy subsequent to FMT. This understanding may lead to future microbiome-based treatments in combination with immunotherapy to significantly increase lung cancer treatment efficacy. In this prospective clinical and molecular study, we will perform an in-depth analysis of the potential role of FMT in the context of immunotherapy.
