Once-a-day oral dosing with omilancor induced clinical remission in 30.4% of active Ulcerative Colitis (UC) patients versus 3.7% in the placebo group (Δ=26.7%, P = 0.01) Once-a-day oral dosing with omilancor in active Crohn’s disease (CD) patients shows promising efficacy in preliminary data with placebo-adjusted clinical remission of 32.6% TITAN-X, proprietary A.I.-powered discovery platform generated highly predictive gene-based biomarkers to enable identification of likely omilancor responders in UC and CD BLACKSBURG, Va.--(BUSINESS WIRE)-- NImmune Biopharma, (“NImmune”), a private late-clinical-stage precision immunology biopharmaceutical company focused on the discovery and development of best-in-class biomarker-driven immunoregulatory therapeutics, led by omilancor, a Phase 3 best in class once daily oral therapy for Ulcerative Colitis, announced that it will present three abstracts, including final Phase 2 data for omilancor in active Ulcerative Colitis patients at the American College of Gastroenterology (“ACG”) 2023 Annual Scientific Meeting (“ACG 2023”), taking place at the Vancouver Convention Center in Vancouver, Canada, between October 20 and October 25, 2023. Dr. Josep Bassaganya-Riera, Founder & CEO of NImmune, said, “Final and complete Phase 2 data for omilancor in mild to severe UC patients with active disease affirms best-in-class efficacy and unrivaled safety. Omilancor is a first-in-class wholly-owned therapeutic, developed with the guidance of TITAN-X, a proprietary computational modeling and AI-powered precision medicine discovery engine that efficiently accelerates biomarker-driven immunoregulatory therapeutic development of omilancor, NIM-1324 and our other immunoregulatory therapeutics. Meeting the primary endpoint of clinical remission in UC patients with active disease substantially de-risks omilancor’s regulatory path to New Drug Application (NDA) and commercialization and provides clinical validation of the LANCL2 pathway as a novel mechanism of action for addressing the significant unmet clinical needs of patients with autoimmune diseases. These positive clinical findings further underscore the importance of our recently announced research collaboration with the NIMML Institute and the value of its advanced computational modeling and A.I.-powered TITAN-X precision medicine platform, which efficiently accelerates biomarker-driven immunoregulatory therapeutic development of omilancor, NIM-1324 and our other immunoregulatory therapeutics.” “As we approach a significant milestone—the initiation of the pivotal global Phase 3 clinical program of omilancor for the treatment of UC by year-end 2023—we are pleased to present our results at ACG 2023 and encouraged by the continued scientific validation of our clinical findings and the overall momentum of omilancor’s clinical and regulatory development. We look forward to continuing to realize the significant potential of omilancor as the first-in-class LANCL2 agonist for UC and additional autoimmune indications including Crohn’s disease and psoriasis.” Presentation Details Title: Efficacy and Safety of Omilancor in a Phase 2 Randomized, Double-Blind, Placebo-Controlled Trial of Patients with Ulcerative Colitis. Poster: Board Number P2216, Monday October 23, 2023, 10:30 AM – 4:15 PM Clinical remission in the approvable UC population of active disease mild to severe patients was induced in 30.4% of patients treated with omilancor relative to 3.7% of patients given placebo (Δ=26.7, P = 0.01), meeting the primary endpoint. Endoscopic and histological remission were achieved in 41.7% of omilancor given patients relative to 18.6% and 22.2%, respectively, patients in the placebo group (Δ=23.1, Δ=19.5). Durable remission was induced in 38.5% of patients in the omilancor group versus 21.4% of patients given placebo (Δ=17.1, P = 0.05). Endoscopic response was achieved in 73.1% of patients treated with omilancor relative to 53.6% of patients given placebo (Δ = 19.5, P = 0.02). Omilancor exhibited statistically significant decreases in TNF-a expressing myeloid cells (p = 0.037) in the colonic mucosa and statistically significant normalization of fecal calprotectin levels (P = 0.048). Oral omilancor was well-tolerated in patients with UC with no trends in AE pro and no dose-limiting toxicities. Pharmacokinetic analysis validated a gut-restricted pro stable drug levels in stool over the treatment period, penetration into colonic biopsy tissue and limited systemic exposure. Title: Efficacy and Safety of Omilancor in a Phase 2 Randomized, Double-Blind, Placebo-Controlled Trial of Patients with Crohn’s Disease. Poster: Board Number P2215, Monday October 23, 2023, 10:30 AM – 4:15 PM PRO-2 clinical remission was achieved in 41.7% of moderate to severe CD patients in the omilancor group relative to 9.1% give placebo (Δ=32.6). Crohn’s disease activity index (CDAI) clinical remission was achieved in 25.0% of omilancor-treated patients relative to 9.1% of the placebo group (Δ=15.9). Omilancor demonstrated a promising efficacy signal in both biologic naïve and biologic-experienced moderate to severe CD patients. Normalization of fecal calprotectin was induced in 33.3% of patients treated with omilancor compared to 14.3% in the placebo group (Δ=19.0). In patients with histological activity in at least one segment at baseline, omilancor induces remission in all segments in 42.9% of patients relative to 20.0% in the placebo group (Δ=22.9). Oral omilancor was well tolerated in patients with CD and displayed a benign safety profile. Title: Transcriptional Analysis of Colonic Biopsies from Patients with Ulcerative Colitis Treated with Omilancor. Poster: Board Number P2217, Monday October 23, 2023, 10:30 AM – 4:15 PM Predictive biomarker signatures from colonic biopsies were identified by using the RandomForest A.I. algorithm within NIMML’s TITAN-X drug development platform. A newly identified precision immunology biomarker signature predicts omilancor responders from non-responders with 75% accuracy and patients treated with omilancor and achieving clinical remission were identified with 100% accuracy. Predictive modeling of gene expression changes from baseline accurately differentiated patients treated with omilancor from those given placebo with 83% accuracy. Biomarkers upregulated by omilancor were associated with lipid metabolism, ion balance, and known critical elements of the LANCL2 pathway. Biomarkers downregulated by omilancor were associated with immune systems processes, mainly linked to neutrophils and leukocyte trafficking. The posters will be available under the “Publications” section of the NIMML’s website at and at the ACG 2023 ePoster Hall during and after the meeting. Additionally, the peer-reviewed accepted abstracts will be published verbatim in a special supplement to the October 2023 issue of The American Journal of Gastroenterology. 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. About Crohn’s Disease (CD) CD is a chronic, autoimmune, inflammatory bowel disease that causes inflammation, irritation and ulcers in any segment of the gastrointestinal tract. CD impacts the end of the small bowel and beginning of the colon most commonly, which in turn can lead to symptoms of abdominal pain, increased abdominal sounds, rectal pain and bleeding, bloody stools, diarrhea, fever, weight loss and malnutrition. There are four classes of CD and treatment depends on the level of severity. Current therapeutic options for severe disease, primarily biologics, have several limitations, which include but are not limited to safety risks for malignancies and infections, limited efficacy and lack of long-term maintenance options. There is an urgent need to establish a consensus for a first-line therapy for CD and improve upon the existing constraints in administration and efficacy. About Omilancor By activating the LANCL2 pathway and modulating the interactions between immunological and metabolic signals in immune and epithelial cells, omilancor is a first-in-class, oral, once-daily, gut restricted therapeutic designed to create a favorable regulatory microenvironment in the gut, decreasing the production of key inflammatory mediators and increasing anti-inflammatory functions in regulatory T cells (Treg) within the site of inflammation. Omilancor has completed Phase 2 clinical testing in UC patients showing a clinical remission of 30.4% with a placebo-adjusted 12-week clinical remission rate of 26.7% (p=0.01) for the 440 mg dose. Following demonstration of a statistically significant approvable primary endpoint for clinical remission in an active disease patient population, NImmune expects to initiate a global pivotal Phase 3 program (PACIFY I and PACIFY II trials) in UC patients in the second half of 2023. Omilancor's target U.S. market size is expected to be valued at $394.9 billion 2021-2030, of which a peak annual market size of $49.5 billion is expected to occur in 2030. NImmune expects peak unadjusted revenue of $12.5 billion in 2030. About NIM-1324 NIM-1324 is an oral, systemically distributed, small-molecule therapeutic candidate which activates LANCL2, a surface membrane-associated receptor that is responsible for modulating key cellular and molecular changes tied to autoimmune diseases. By activating the LANCL2 pathway, NIM-1324 increases the anti-inflammatory capacity and stability of regulatory CD4+ T cells while also supporting the metabolic demands of autophagy in phagocytes. To date, treatment with NIM-1324 has reduced the production of interferon alpha in human peripheral blood mononuclear cells (PBMCs) from systemic lupus erythematosus (SLE) patients and provided protection from clinical disease and tissue pathology in mouse models of lupus, rheumatoid arthritis, and multiple sclerosis. Phase 2-ready NIM-1324 completed Phase 1 clinical testing where it met all endpoints and demonstrated a dose proportional change in plasma exposure within the therapeutic range with no accumulation. NIM-1324 target U.S. market size is expected to be valued at $226.0 billion 2021-2030, of which a peak annual market size of $23.1 billion is expected to occur in 2030. NImmune expects unadjusted revenue estimates from NIM-1324 therapeutics to be valued at $2.3 billion from the 2028-2030 projections.
