- Agreements provide IP license bolstering Company's strong patent portfolio -
CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Seres Therapeutics, Inc. (NASDAQ:MCRB), a leading microbiome therapeutics platform company, today announced that it has entered into a strategic, multi-year research collaboration with Memorial Sloan Kettering Cancer Center (MSK). The collaboration will support the translation of novel discoveries from MSK laboratories into first-in-field microbiome therapeutics across multiple new cancer indications, where the microbiome may play a critical role.
Seres and MSK have agreed to collaborate in two diverse areas of focus related to the discovery and development of microbiome therapeutics: (1) improving the morbidity and mortality outcomes of patients undergoing Hematopoietic Stem Cell Transplantation (HSCT) for treatment of cancer, by prevention of Transplant-Related Infections and Graft Versus Host Disease (GVHD); and (2) increasing the efficacy and safety of checkpoint inhibitors used for immuno-oncology treatment. Both areas will be targeted using rationally-designed consortia of microbiome bacteria, a technology which Seres has pioneered in other therapeutic areas.
Seres and MSK have agreed to work jointly under a multi-year sponsored research agreement where Seres will collaborate with MSK investigators to study patient samples from MSK clinical studies, generating microbiome metagenomic signatures as well as other clinical data that are expected to aid in the design of novel microbiome therapeutics in these targeted disease states. The agreements also provide Seres with a global license to MSK's intellectual property related to the use of bacterial compositions in treating HSCT patients and related areas, further bolstering Seres' broad existing composition of matter and method of use patent estate.
"MSK scientists have been at the forefront of research into the crucial role of the microbiome in disease, and we believe our combined insights and capabilities could be strongly synergistic and pave the way toward clinically meaningful therapeutic applications for patients with various cancers and serious conditions related to their treatment," said Roger Pomerantz, M.D., President, CEO and Chairman of Seres.
In HSCT, MSK investigators, led by Marcel van den Brink, M.D., Ph.D., have published clinical studies demonstrating a relationship between the diversity and composition of the microbiome in HSCT patients and their increased risk of bacterial infections and GVHD, both of which contribute to overall all-cause mortality.1,2 Seres is currently developing SER-155, a rationally-designed, preclinical stage therapeutic candidate comprised of in vitro cultured bacterial species that aims to improve morbidity and mortality outcomes in HSCT patients.
In the area of immuno-oncology, researchers from Seres and MSK will also work together with the goal of discovering precisely how the microbiome could improve the efficacy and safety of immuno-oncology checkpoint inhibitors. This research builds upon a recent MSK publication which describes, for the first time, the important role of the microbiome in the development of immunological adverse events in patients, and related preclinical work showing that the microbiome can enhance the efficacy of checkpoint inhibitors.3,4
"We are looking forward to collaborating with Seres, a global leader in the development of microbiome therapeutics, as we work together to advance our collective insights into meaningful clinical advances for patients. Based upon our research in cancer patients as well as animal models at MSK, we believe there is potential to improve patient outcomes by addressing the critical roles of the microbiome," said Dr. van den Brink.
About Seres Therapeutics
Seres Therapeutics, Inc. is a leading microbiome therapeutics platform company developing a novel class of biological drugs that are designed to treat disease by restoring the function of a dysbiotic microbiome, where the natural state of bacterial diversity and function is imbalanced. Seres' most advanced program, SER-109, has successfully completed a Phase 1b/2 study demonstrating a clinical benefit in patients with recurring Clostridium Difficile infection (CDI) and is currently being evaluated in a Phase 2 study in recurring CDI. The FDA has granted SER-109 Orphan Drug, as well as Breakthrough Therapy, designations. Seres' second clinical candidate, SER-287, is being evaluated in a Phase 1b study in patients with mild-to-moderate ulcerative colitis (UC).

Hematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. The procedure is used as part of the treatment of certain blood cancers. An estimated 22,000 allogeneic HSCT procedures are performed in the US and EU each year. HSCT patients experience elevated mortality risk due to infection, Graft Versus Host Disease (GVHD) and cancer recurrence.
About Immuno-Oncology and Checkpoint Inhibitors
Immuno-oncology treatment uses or enhances the patient's own immune system to be able to stop the growth of cancer cells. The composition of a patient's microbiome has been shown to impact this immune response. Several immuno-oncology checkpoint inhibitors, including nivolumab (Opdivo®), ipilimumab (Yervoy®) and pembrolizumab (Keytruda®) are FDA approved and indicated to treat various cancers. While immuno-oncology treatment can lead to profound clinical responses, these therapies are effective in a minority of patients who use them. Also, the clinical utility of immuno-oncology products can be limited by serious immune mediated adverse events observed in some patients.
