Clinical Trial 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.


Description:

Only a small subset of tumor types benefit from immune checkpoint inhibitor therapy, where most responders eventually develop resistance. Oral administration of Fecal Microbiota Transplantation (FMT) from treatment-responsive patients has been found to considerably improve Programmed death-ligand 1 (PD-L1)-based immunotherapy outcomes as well as inhibit tumor growth through augmented dendritic cell and T cell responses. This study aims to investigate the safety and efficacy of FMT treatment combined with first-line (chemo-)immunotherapy in metastatic lung cancer. The study will include a thorough microbiome composition analysis of FMT donors and recipients to be correlated to clinical outcomes. In addition, blood samples will be analyzed using a novel commensal antigen microarray for rapid serum profiling. Patients with metastatic malignancy who completely respond to immunotherapy will serve as the fecal implant donors. Dr. Arik Segal's Lab will produce capsules with one donor/capsule. In an open-label approach, patients will receive FMT on the first day of (chemo-)immunotherapy cycle one and every 3-4 weeks based on the specific (chemo-)immunotherapy protocol. Before FMT treatment, participants will receive active antibiotics. The second arm will receive standard-of-care treatment only. Study participants will be evaluated throughout the study using imaging, laboratory, vital signs, and disease status assessments until the end of the study. Stool samples from study participants will be collected before the start of treatment during the (chemo-)immunotherapy cycle and at the end of treatment for sequencing and bioinformatics analysis of the microbiome. Blood samples will be collected from all donors at the study start and from all recipients at recruitment, on the day of each FMT administration, and at the end of treatment. Statistics: A one-sided test for differences in proportions and type I error of 0.05 will have a power of 88% to detect a 30% difference in response between the FMT and placebo group, for a total of 80 randomized patients, 40 in each treatment group stratified by PD-L1 status.
