Symbiotix Biotherapies Receives $5 Million in Institutional Financing to Advance its Development of Molecular Therapeutics that Modulate Regulatory T Cell Activity

BOSTON – November 1, 2017 – Symbiotix Biotherapies, Inc. (“Symbiotix”), a pioneering microbiome company developing novel molecular therapeutics based on the human microbiome, today announced the completion of $5 million in institutional financing from Kairos Ventures, LLC.  Built on over two decades of groundbreaking research that has been elucidating how molecules produced by our gut microbiota modulate the human immune system, the Company’s Scientific Co-Founders are three of the most distinguished thought leaders in the microbiome field:

-Prof. Dennis Kasper, M.D., the William Ellery Channing Professor of Medicine and Professor of Microbiology and Immunobiology at Harvard Medical School

-Prof. Sarkis Mazmanian, Ph.D., the Louis & Nelly Soux Professor of Microbiology in the Division of Biology & Biological Engineering at the California Institute of Technology

-Prof. Lloyd Kasper, M.D., Professor of Medicine, Microbiology and Immunology at Geisel School of Medicine at Dartmouth College

As one of the earliest companies that launched the microbiome sector, Symbiotix has been steadily advancing first-in-class programs that modulate regulatory T cell (Treg) activity and are now described by over 100 scientific publications from the Company’s Scientific Co-Founders. “At Symbiotix, we’ve been fortunate in having been able to attract significant non-dilutive capital over the years,” said Nader Yaghoubi, M.D., Ph.D., President and Chief Executive Officer of Symbiotix.  “As we position ourselves for commencing human clinical trials, the Kairos equity financing enables us to further accelerate our programs and complete necessary work in preparation for clinical trials.”

With an extensive intellectual property portfolio which now includes 22 issued patents and multiple pending cases licensed from California Institute of Technology, Brigham and Women’s Hospital and Dartmouth College, Symbiotix has built a dominant IP portfolio that covers Reglemers™, first-in-class molecules that modulate Treg activity.  Just this year, the United States Patent and Trademark Office awarded the very first composition-of-matter patent on a molecule that has emerged from the human microbiome.  This patent, U.S. 9,539,281, covering the company’s lead clinical candidate, SYMB-104, is part of the exclusively licensed Symbiotix intellectual property portfolio.

According to Jim Demetriades, Managing Partner at Kairos Ventures, “We are proud to lead this equity round in Symbiotix, one of the first companies to recognize the importance of the microbiome in addressing autoimmune diseases. Symbiotix is led by a group of world class scientists, who have created significant, and well protected, intellectual property. We are tremendously excited about Symbiotix, a company that combines all of the elements we look for in a Kairos portfolio company.”
