Calgary Researchers Discover a Novel Approach to Treatment of Inflammatory Bowel Diseases (IBD) Using Hydrogen Sulfide Technology

TORONTO, CANADA — (May 24, 2018) – Antibe Therapeutics Inc. (“Antibe” or the “Company”) (TSXV: ATE, OTCQB: ATBPF) is pleased to announce that a team of researchers at the University of Calgary has identified a key mechanism underlying the ability of certain intestinal bacteria to contribute to the ulceration and inflammation that is characteristic of Crohn’s disease and ulcerative colitis (the two forms of IBD).  Moreover, they have demonstrated that novel hydrogen sulfide-releasing drugs can reverse these effects, leading to resolution of the inflammation and healing of intestinal ulcers. The research was directed by two of Antibe’s founders, Drs. Andre Buret and John Wallace.

Dr. Buret explained that “intestinal bacteria that cause damage and bleeding in patients with IBD are described as “virulent” (harmful, destructive), and this virulence is dependent upon the availability of iron to the bacteria within the intestine. Depriving bacteria of access to iron markedly reduces virulence, resulting in a dramatic reduction of the severity of colitis.”

The Calgary research team demonstrated that novel hydrogen sulfide-releasing drugs (ATB-428 and ATB-429) were capable of scavenging iron within the intestines, depriving bacteria of access to that iron, and thereby markedly reducing bacterial virulence. Dr. Wallace commented that “the hydrogen sulfide-releasing drugs did not cause dramatic changes to the types of bacteria that reside in the intestine; rather, the treatment rendered the intestinal bacteria much less toxic to the intestinal tissues.” Studies were performed both in rats in which colitis had been induced, and using tissues obtained from patients with ulcerative colitis or Crohn’s disease.  Dr. Wallace added, “previous studies performed in our laboratories have documented the profound beneficial effects of our hydrogen sulfide-releasing drugs in protecting intestinal cells from damage and promoting healing.”

This research was supported by grants to Drs. Buret and Wallace from the Canadian Institutes of Health Research, Crohn’s Colitis Canada and the National Science and Engineering Research Council of Canada.
