COMPOSITIONS FOR MODULATING GUT MICROFLORA POPULATIONS, ENHANCING DRUG POTENCY AND TREATING CANCER, AND METHODS FOR MAKING AND USING SAME

Provided are compositions, including products of manufacture and kits, and methods, comprising combinations of microbes, such as non-pathogenic, live bacteria and/or bacterial spores, for the control, amelioration, prevention, and treatment of a disease or condition, for example, a cancer. In alternative embodiment, these non-pathogenic, live bacteria and/or bacterial spores are administered to an individual in need thereof, thereby resulting in a modification or modulation of the individual's gut microfloral population(s). In alternative embodiments, by modulating or modifying the individual's gut microbial population(s) using compositions, products of manufacture and methods as provided herein, the pharmacodynamics of a drug administered to the individual is altered, thereby controlling, ameliorating, preventing and/or treating of that cancer. Combinations of microbes are administered with chemotherapy, radiation therapy, an immune checkpoint inhibitor, a Chimeric Antigen Receptor T-cell therapy or other immunotherapy or cancer treatment.
