BLACKSBURG, Va.—(BUSINESS WIRE)—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 characterize the safety profile of BT-11, its orally-active, gut-restricted investigational new drug (IND) for Crohn’s disease (CD) and ulcerative colitis (UC), in the International Journal of Toxicology published in association with the American College of Toxicology. The definitive non-clinical toxicity studies evaluated general and specific toxicities that are common safety concerns for pharmaceuticals. The data collected indicates that BT-11 does not induce any form of general toxicity, targeted organ or other specific toxicities in rats and dogs treated in pivotal, 90-day repeat-dose toxicity studies.

“The results of 90-day toxicity studies along with ongoing chronic toxicity studies continue to illustrate that BT-11 has a benign safety profile and shows an enormous potential as an oral therapeutic for IBD showing no safety concerns on target organ systems or genotoxicity,” said Dr. Josep Bassaganya-Riera, Chairman and CEO of Landos. “We are pleased that the findings from these IND-enabling studies were validated by the results of Phase 1 first-in-human clinical testing in 70 normal healthy volunteers showing no differences in adverse event profile between placebo and BT-11 groups. Together, these study results support the evaluation of BT-11 in Phase 2 therapeutic efficacy studies in UC and CD patients, which Landos has initiated. BT-11 has the potential to address the unmet clinical need for safer and more effective drugs and disrupt the $10 billion IBD therapeutics market.”

The study, Non-clinical Toxicology and Toxicokinetic Profile of an Oral Lanthionine Synthetase C-Like 2 (LANCL2) Agonist, BT-11, was authored by researchers at Landos. These studies tested BT-11 under Good Laboratory Practice (GLP) conditions in 90-day, repeat dose studies that evaluated general toxicity as well as toxicokinetic (TK), metabolic, genotoxic, respiratory, cardiovascular, and central nervous system responses. These non-clinical studies show BT-11 to be a safe and well-tolerated oral therapeutic with potential as a potent, new immunometabolic drug for UC and CD, with “no-observed adverse effect level” (NOAEL) >1,000 mg/kg.

About BT-11

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 markers 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.

About IBD

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.
