Topline results are expected in the first half of 2022

A whole blood LABP-104 precision medicine signature will be assessed during the trial

BLACKSBURG, Va., Oct. 28, 2021 (GLOBE NEWSWIRE) -- Landos Biopharma, Inc. (NASDAQ: LABP), a late-clinical-stage biopharmaceutical company utilizing its LANCE Advanced A.I. platform to discover and develop novel therapeutics for patients with autoimmune diseases, today announced the Company has dosed the first subject in a Phase 1 study of LABP-104,a potentially first-in-class oral, small-molecule LANCL2 agonist, for the treatment of systemic lupus erythematosus (SLE).

We are pleased to announce the initiation of the first clinical trial investigating LABP-104, marking Landos sixth novel clinical program addressing the unmet clinical needs of patients with autoimmune diseases, said Dr. Josep Bassaganya-Riera, Chairman, President, and CEO of Landos.Our LANCE platform coupled with our agile entrepreneurial culture continues to deliver high value shots on goal. There are approximately 1.5 million patients in the U.S. suffering from SLE with very limited therapeutic options. Leveraging our LANCE platform to develop a proprietary LABP-104 transcriptional response signature in blood holds promise to identify the SLE patients that may benefit the most from oral LABP-104 treatment. We are excited to advance LABP-104 as the first potential precision medicine-based therapeutic candidate for SLE into clinical testing.

The Phase 1 trial is a randomized, placebo-controlled, double-blind, ascending dose, multi-cohort study designed to evaluate the safety, tolerability and pharmacokinetics of LABP-104 in healthy volunteers. A total of 56 healthy volunteers will be enrolled in two parts a single ascending dose study (SAD) and then a multiple ascending dose study (MAD), during which the participants will be randomized to five cohorts receiving single oral doses of LABP-104 or placebo in the SAD and to three cohorts receiving three oral doses of LABP-104 or placebo once daily for seven days in the MAD. The primary endpoint will measure the safety and tolerability of LABP-104. Secondary endpoint will measure the pharmacokinetics of LABP-104. We expect to report topline results of the Phase 1 trial in the first half of 2022. Additional information about the Phase 1 LABP-104 trial is available atclinicaltrials.gov(NCT05019950).

By using the LANCE Advanced A.I. platform, Landos has developed a 15-gene LABP-104 transcriptional response signature in whole blood that could be used as a companion diagnostic to better characterize the subsets of lupus patients that can benefit the most from oral treatment with LABP-104. This precision medicine signature will be further validated as an exploratory endpoint in Phase 1 and 2 SLE studies.

About Systemic Lupus Erythematosus (SLE)Systemic lupus erythematosus (SLE) is the most common type of the autoimmune disease lupus. In SLE, the immune system attacks its own tissues, causing widespread inflammation and tissue damage. SLE can affect multiple organs and systems including skin, joints, kidneys, brain, blood cells, lungs and heart. SLE is commonly treated with corticosteroids and antimalarials that aim to lower the interferon alpha response, which elicit strong antiviral activities in target cells. However, current therapeutic options for SLE can cause serious side effects, including the potential for cardiovascular damage, increased risk of infections, sepsis and pneumonia. Newly-FDA-approved therapies for SLE are infusions into a vein in the arm that can cause upper respiratory tract infections, bronchitis, infusion-related reactions and herpes zoster (shingles). As such, there is a high unmet medical need for an alternative oral frontline therapy for the estimated 1.5 million SLE patients in the US and approximately 5 million patients globally, with an estimated market value of approximately $1.6 billion by 2028 and a growth rate of 5.6%.

About LABP-104LABP-104 is an oral, once-daily, 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, LABP-104 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 LABP-104 has reduced the production of interferon alpha in human PBMCs from SLE patients and provided protection from clinical disease and tissue pathology in mouse models of lupus. We own an issued patent on LABP-104 in the U.S., a number of foreign patent applications, and an international patent application available for filing in additional foreign countries and regions through the Patent Cooperation Treaty.

About Landos BiopharmaLandos Biopharma is a late-clinical-stage biopharmaceutical company utilizing its LANCE Advanced A.I. platform to discover and develop novel therapeutics for patients with autoimmune diseases. Using the LANCE platform, the Company has discovered new mechanisms of action, including the LANCL2, NLRX1 and PLXDC2 immunometabolic pathways. Landos Biopharma has 17 active development programs targeting these novel pathways at the interface of immunity and metabolism. Its lead product candidate, omilancor targets the LANCL2 pathway and is a novel oral, gut-restricted, small-molecule potentially first-in-class therapeutic currently being prepared for global pivotal Phase 3 trials for the treatment of ulcerative colitis, in two active Phase 2 trials in Crohns disease, and is anticipated to initiate Phase 1 studies in eosinophilic esophagitis in 2022. Omilancor is also being studied in a topical formulation for psoriasis and atopic dermatitis. NX-13 is a novel, oral, gut-restricted small-molecule drug candidate that targets the NLRX1 pathway and is currently in an active Phase 1b trial in ulcerative colitis. NX-13 targets the NLRX1 pathway. Landos sixth new clinical product candidate, LABP-104, is in an active Phase 1 trial for systemic lupus erythematosus guided by a proprietary 15-gene precision medicine companion diagnostic developed by its LANCE advanced A.I. platform. Additional product candidates in Landos expansible inflammation and immunology pipeline are in preclinical and IND-enabling stages of development.
