BLACKSBURG, Va., June 14, 2021 (GLOBE NEWSWIRE) -- Landos Biopharma, Inc. (NASDAQ: LABP), a late-clinical-stage biopharmaceutical company utilizing its LANCE Advanced Artificial Intelligence (A.I.) platform to discover and develop novel oral therapeutics for patients with autoimmune and inflammatory diseases, today announced the successful outcome of an End-of-Phase 2 (EOP2) meeting with the U.S. Food and Drug Administration (FDA) for omilancor, its lead candidate in late-stage clinical development for the treatment of mild-to-moderate active ulcerative colitis (UC) patients. Landos and the FDA agreed on key elements necessary for regulatory approval, clearing a path forward for a global pivotal Phase 3 program with omilancor in patients with mild-to-moderate active UC.
The global pivotal PACIFY program will include two global pivotal Phase 3 clinical trials (PACIFY I and PACIFY II) and evaluate a single dose of omilancor versus placebo, with primary endpoints of clinical remission at weeks 12 and 52 to support label claims of induction and maintenance of clinical remission measured using the 3-component Mayo score. Landos is working to finalize the details of the Phase 3 protocols based on feedback and guidance from the FDA.
“We are pleased with the results of our End-of-Phase 2 meeting with the FDA and are excited to be able to progress omilancor into Phase 3 development as a potentially improved treatment option for a broad population of patients with mild-to-moderate active UC worldwide,” said Josep Bassaganya-Riera, Chairman, President and Chief Executive Officer of Landos. “Our Phase 2 results indicated omilancor was well-tolerated with strong efficacy signals, which we believe support its potential as a pre- and post-biologic broad-spectrum therapy for UC patients, and provided us with invaluable insights for the design of our Phase 3 PACIFY trials. We are appreciative of the support and guidance from the FDA and are working to initiate the Phase 3 global program in the U.S., Europe and Asia, to support regulatory approvals in the U.S., European and Asian markets.”
The Phase 3 design was supported by nonclinical and clinical safety and efficacy data, including encouraging results from a Phase 2 study that evaluated omilancor in 198 patients with mild-to-moderate active UC and which demonstrated statistically significant immunological and biomarker results that mirror activation of the novel LANCL2 mechanism by omilancor in the gut. Phase 1 and Phase 2 clinical data demonstrated that omilancor was well tolerated at all doses evaluated, with no dose-limiting toxicities.
About Ulcerative Colitis (UC)
UC is a chronic, autoimmune, inflammatory bowel disease that causes inflammation, irritation, and ulcers in the lining of the large intestine (colon) and rectum. Symptoms include abdominal pain, rectal pain and bleeding, bloody stools, diarrhea, fever, weight loss, and malnutrition. Having UC puts a patient at increased risk of developing colon cancer. Diagnosis typically occurs in early adulthood and the disease requires maintenance treatment for the remainder of the patient’s life. UC is estimated to affect over 900,000 patients in the United States and over 1 million patients throughout the rest of the world. With 70% of addressable patients experiencing a second flare within one year and 30% of patients in remission failing to stay in remission for more than one year, there is an unmet medical need in UC for safer and more efficacious therapeutics.
Discovered using Landos proprietary LANCE Advanced A.I. platform, omilancor is a novel, oral, gut-restricted small molecule investigational drug that targets the Lanthionine Synthetase C-Like 2 (LANCL2) pathway impacting the gastrointestinal tract. LANCL2 plays an important role in the immunoregulatory process. By activating the LANCL2 pathway and modulating the interactions between immunological and metabolic signals in immune cells, omilancor is designed to create a favorable regulatory microenvironment in the gut, decreasing the production of key inflammatory mediators and increasing anti-inflammatory markers in regulatory T cells (Treg) within the site of inflammation. Landos reported initial Phase 2 results of omilancor evaluating patients with ulcerative colitis in 2021 and expects to initiate a global pivotal Phase 3 program (PACIFY I and PACIFY II trials) in patients with mild-to-moderately active UC. Additionally, Landos initiated a Phase 2 trial of omilancor in patients with Crohn’s disease in the first half of 2021.
