Landos Biopharma, Inc., a clinical-stage biopharmaceutical company focused on the discovery and development of first-in-class oral therapeutics for patients with autoimmune diseases, announced the publication of findings that further elucidate the regulatory arm of the novel mechanism of action for BT-11, its investigational new drug (IND) for Crohn’s disease and ulcerative colitis, in the Journal of Immunology. This study investigated the immunoregulatory mechanisms by which oral treatment with BT-11 provides protection from inflammatory bowel disease (IBD). The study concludes that BT-11 effectively induces and maintains lasting immune tolerance in the gastrointestinal tract through immunoregulatory mechanisms mediated by CD4+ regulatory T (Treg) cells.
“These results illustrate that BT-11’s novel, dual mechanism shows direct anti-inflammatory and pro-regulatory effects that represent a unique differentiator when compared to current therapeutics for autoimmune diseases as well as the majority of those in development,” said Dr. Josep Bassaganya-Riera, Chairman and CEO of Landos. “BT-11 represents a first-in-class, oral, gut-restricted, chronic therapeutic to treat ulcerative colitis and Crohn’s disease that can potentially improve safety, efficacy, tolerability and convenience thus affording an unprecedented opportunity to disrupt the $10 billion IBD therapeutics market and address the unmet clinical need for safer and more effective drugs.”
The study, Oral Treatment with BT-11 Ameliorates Inflammatory Bowel Disease by Enhancing Regulatory T Cell Responses in the Gut, was authored by researchers at Landos and aimed to validate the critical importance of regulatory CD4+ T cells for the therapeutic efficacy of BT-11 in IBD. The study further defined the cellular and molecular mechanisms of BT-11 in the colonic mucosa and found evidence that BT-11 establishes long-lasting effects on the maintenance and promotion of immune tolerance in the GI tract.
Details from the study:
Landos’ lead clinical asset, BT-11, is a novel, oral, gut-restricted investigational new drug (IND) targeting the Lanthionine Synthetase C-Like 2 (LANCL2) pathway in the gastrointestinal tract for the treatment of Crohn’s disease (CD) and ulcerative colitis (UC). BT-11 intercepts IBD by decreasing the production of inflammatory mediators and increasing anti-inflammatory molecules within the gastrointestinal tract. BT-11 has shown outstanding therapeutic efficacy in preclinical models of inflammatory bowel disease (IBD), a benign safety profile without the concerns of systemic exposure and has two open INDs for evaluation in UC and CD. The Company completed Phase 1 testing of BT-11 in 2018 and plans to initiate Phase 2 testing in 2019.
IBD represents a group of chronic and disabling disorders that greatly impacts a patient’s quality of life. The two primary clinical manifestations of IBD - Crohn’s disease (CD) and ulcerative colitis (UC) - afflict 3 million Americans and 5 million people worldwide, with nearly 25% growth in prevalence over the last five years. There is an unmet clinical need for safer, more effective medications for these diseases as currently marketed therapeutics have a number of drawbacks: they only benefit a small number of the overall population, lose response effectiveness, or cause high rates of serious side effects, including cancer, infection, and death.
About Landos Biopharma
Landos Biopharma, Inc. is a clinical-stage biopharmaceutical company focused on the discovery and development of first-in-class oral therapeutics for patients with autoimmune diseases. Landos’ lead clinical asset, BT-11, is a first-in-class, oral therapeutic that acts locally in the gastrointestinal tract for treatment of inflammatory bowel disease (IBD). The company has completed Phase 1 clinical testing and plans to initiate Phase 2 clinical testing of BT-11 for inflammatory bowel disease in 2019. Landos also has a robust pipeline of new compounds for other autoimmune diseases, several of which will advance to IND in 2019. Landos is headquartered in Blacksburg, VA.
