Oral treatment with LABP-104 in preclinical models of Systemic Lupus Erythematosus (SLE) resulted in enhanced Treg function, decreased kidney inflammation and reduced interferon gamma signaling

Phase 1 clinical trial anticipated to begin during Q4 2021

BLACKSBURG, Va., Sept. 15, 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 oral therapeutics for patients with autoimmune diseases, today announced that it will present preclinical data of LABP-104, an oral, small-molecule LANCL2 agonist, in Systemic Lupus Erythematosus (SLE or Lupus) as an oral presentation at the upcoming American College of Rheumatology (ACR) Convergence 2021. The meeting will be held virtually from November 3-10, 2021.

These novel findings support the potential therapeutic efficacy of LABP-104 in SLE, along with the power of our LANCE platform to discover and validate novel targets at the intersection of immunity and metabolism. Altogether, they highlight the breadth and depth of our expansible inflammation and immunology pipeline, said Dr. Josep Bassaganya-Riera, Chairman, President and Chief Executive Officer of Landos. Our Phase 2 trial with omilancor in ulcerative colitis illustrated the important immunoregulatory mechanisms of the Lanthionine Synthetase C-Like 2 (LANCL2) pathway including enhancing regulatory T cell (Treg) function. With these new data in lupus, we have further validation of LABP-104s therapeutic potential to activate this pathways ability to intercept and possibly reverse the complex cascade of immunological events that lead to disease and pathology in lupus patients. We plan to pursue development of LABP-104 in lupus in addition to other debilitating autoimmune diseases with unmet clinical needs, where enhancement of Treg function plays an important therapeutic role.

Landos expects to enter Phase 1 clinical testing of LABP-104 as an oral therapeutic candidate for lupus during the fourth quarter of 2021, further expanding the companys deep inflammation and immunology pipeline.

ACR 2021 Presentation Details

Title: Therapeutic Efficacy of LABP-104, an Oral LANCL2 Agonist, for the Treatment of Systemic Lupus ErythematosusPresentation ID: 1815680Session: Abstracts: SLE Animal Models Date/Time: Saturday, November 6, 2021, from 11:15 to 11:30 a.m. EDT

Highlights Include:

-- Oral treatment with LABP-104 protected against worsening from baseline in proteinuria grade in greater than 90% of mice, improved proteinuria grade in roughly 50% of mice and reduced anti-nuclear antibody levels by three-fold. -- Reduced overall histological score in the kidneys, including improvement in interstitial inflammation, glomerular proliferation and cellular crescents as well as significantly reduced effector IL-17+ and IL-21+ CD4+ T cells in the spleen while significantly increasing CD25+ FOXP3+ regulatory CD4+ T cells (Treg). -- Significantly reduced the production of interferon alpha in human peripheral blood mononuclear cells (PBMCs) from SLE patients in response to general, TLR7 and CpG oligonucleotide stimuli.

The presentation will be available under the Publications section of the Companys website at www.landosbiopharma.com concurrent with the live presentation on November 6, 2021.

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. As such, there is a high unmet medical need for an alternative 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-104

LABP-104 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, 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. Landos expects to enter Phase 1 clinical testing in healthy volunteers in Q4 2021.

About Landos BiopharmaLandos Biopharma is a late-clinical-stage biopharmaceutical company utilizing its LANCE Advanced A.I. platform to discover and develop novel oral 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 an active Phase 2 trial 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. Landos has another novel, oral, gut-restricted small-molecule drug candidate, NX-13, that is being investigated in an active Phase 1b trial in ulcerative colitis. NX-13 targets the NLRX1 pathway. Additional product candidates are in development for the treatment of lupus nephritis, rheumatoid arthritis, multiple sclerosis, Alzheimers disease, non-alcoholic steatohepatitis (NASH), asthma, chronic obstructive pulmonary disease (COPD), diabetes, and diabetic nephropathy.
