Exhibit 99.1

Landos Biopharma Provides Business Update and
Reports First Quarter 2023 Results

NEXUS Phase 2 Clinical Trial of NX-13 for Ulcerative Colitis Initiated

NEXUS Top-line Results Planned for Q4 2024

Sufficient Cash to Fund Planned Operations into First Half of 2025

NEW YORK, May 12, 2023 –– Landos Biopharma, Inc. (NASDAQ: LABP), a clinical-stage biopharmaceutical company developing novel, oral medicines for patients with autoimmune diseases, today provided a business update and announced financial results for the first quarter ended March 31, 2023.

“We continue to execute on a focused strategy for the NX-13 program to maximize value for our shareholders,” said Gregory Oakes, President and CEO of Landos. “Our NEXUS Phase 2 study of NX-13 in UC is designed to advance this important program with a goal to generate meaningful data and build on the promising early signals of clinical improvement from our Phase 1b trial. We firmly believe in the potential of NX-13 to transform the current treatment paradigm for patients with moderate-to-severe UC.”

Clinical Development Updates

NX-13 is a novel, oral, gut-selective, NLRX1 agonist in development as a once-daily treatment for ulcerative colitis (UC).

In April 2023, the Company initiated the NEXUS Phase 2 proof-of-concept clinical trial of NX-13 with our first site activations. The Phase 2 study is a randomized, statistically powered, multicenter, double-blind, placebo-controlled, multiple dose, 12-week induction study evaluating 80 patients with moderate to severe UC with a long-term extension (LTE) period out to one year. All subjects will be randomized to receive either 250 mg or 750 mg immediate release NX-13 treatment regimens, or placebo. The primary objective of the trial will be to evaluate the clinical efficacy, safety and pharmacokinetics of oral NX-13 vs placebo (NCT05785715 ClinicalTrials.gov).
The NEXUS trial remains on track to begin dosing patients in the second quarter of 2023 with topline results expected by the fourth quarter of 2024.

Corporate Updates

The Company has taken important steps to strengthen its operations and sharpen its near-term strategic focus on advancing the clinical development of NX-13 including the following:

Secured $16.6 million in net proceeds from the sale of pre-funded warrants in January 2023.
Transferred the LANCL portfolio, including omilancor, LABP-104 and LABP-111, to Dr. Josep Bassaganya-Riera and certain affiliated individuals and entities in February 2023.

 


 

Repurchased and retired 9.1 million shares of common stock owned by Dr. Josep Bassaganya-Riera and certain affiliated individuals and entities for an aggregate price of $3.0 million in February 2023.

Summary of First Quarter 2023 Results

Cash, cash equivalents and marketable securities were $50.0 million as of March 31, 2023, as compared to $44.4 million on December 31, 2022. The Company expects that its cash position will be sufficient to fund operating expenses and capital requirements into the first half of 2025.

Research and development expenses were $3.3 million for the first quarter of 2023, compared to $10.8 million for the first quarter of 2022. The decrease was primarily attributed to reduced clinical activities for omilancor and LABP-104 programs due to the wind down of the related clinical trials, as well as decreases in consulting costs and depreciation expense.

General and administrative expenses were $3.2 million for the first quarter of 2023, compared to $4.2 million for the first quarter of 2022. The decrease was primarily attributable to a decrease in consulting costs and stock-based compensation, as well as a prior year loss on a lease termination that didn’t recur in the current period, partially offset by increases in legal fees associated with the asset purchase agreement entered into with Dr. Josep Bassaganya-Riera and certain affiliated individuals and entities.

About Landos Biopharma

Landos Biopharma is a clinical stage biopharmaceutical company focused on the development of first-in-class, oral therapeutics for patients with autoimmune diseases. Our mission is to create safer and more effective treatments that address the therapeutic gap in the current treatment paradigm.

We have a portfolio of novel targets anchoring two libraries of immunometabolic modulation pathways, including four potentially first-in-class, once-daily, oral therapies targeting eight indications in the immunology space.

We are currently focused on advancing the clinical development of NX-13 in UC. We initiated our NEXUS Phase 2 proof-of-concept trial in April 2023 and expect to report topline results by the fourth quarter of 2024.

NX-13 Unique Bimodal MOA Targets NLRX1 Pathways for Treatment of Ulcerative Colitis (UC) Leber et al. J Immunology 2019 NX-13 is an oral, once-daily therapy being developed for moderate to severe UC Novel NLRX1 agonist Bimodal MOA aims to reduce reactive oxygen species intracellularly and inflammatory pathways extracellularly to reduce UC symptoms and flares NLRX1: the NEXUS of Immunometabolism mitochondrial-associated anti-inflammatory NOD-like receptor (NLR) Direct metabolic role in mitochondria Direct anti-inflammatory role as NLR NX-13 NLRX1


Slide 5

Therapeutic Challenges Present Large Unmet Need for UC Patients Active UC Induction Therapy to reach clinical/endoscopic remission Maintenance Therapy to maintain clinical and endoscopic remission Insufficient response Relapse Ulcerative Colitis Chronic colonic inflammation with rectal bleeding and diarrhea Patients experience relapsing (flares) and remitting episodes of disease severity Therapeutic Goals induce and maintain steroid-free symptom relief healing of colon lining improved quality of life Therapeutic Challenges Limited Efficacy: many patients do not respond or lose response to treatment Safety Risks: infections, cancer, blood clots or cardiac events

Slide 7

Immune Function is Intimately Tied to the Intracellular Environment of Processing & Using Energy The intracellular immunometabolic state (the processing & using of energy through glycolysis or mitochondrial metabolism) provides a baseline, and can affect cellular response as pro- or anti-inflammatory Many proteins, molecules & substrates have dual action on cellular metabolism AND immune function The underlying intracellular (internal) immunometabolic environment can affect the response of multiple cells involved in UC and gut homeostasis (including T cells, antigen presenting cells, and epithelial cells) O’Neill et al,. Nat Rev Immunol 2016; Chi, Cell & Mol Immuno 2022 Pro-inflammatory cells use glycolysis to generate energy and biosynthetic intermediates fast Anti-inflammatory cells use mitochondria to supply steady energy to maintain tolerance over time Glycolysis favors pro-inflammatory actions Extracellular Inflammatory Cells & Cytokines Mitochondrial metabolism favors anti-inflammatory actions Pro-inflammatory or Anti-inflammatory response Cytokines Microbiome Other cells


Slide 8

The Role of Immunometabolism in Immunology & UC Immunometabolic response in inflammatory diseases in the immunology universe & UC: Abnormal or imbalanced immune activation of the response resulting in over abundance of pro-inflammatory cells & cytokines with lack of anti-inflammatory control. In UC, Pathogens cross the damaged epithelial barrier, activating immune response ​ Immune activation is energetically costly, requiring the cell to use fast & inefficient glycolytic metabolism. Multiple Factors contribute to the UC Inflammation Cycle: Low grade Mucosal Inflammation and microbiome dysbiosis Epithelial Cell Damage and barrier disruption Broad Immune Activation favoring pro-inflammatory cells and cytokines Global Data Report GDHC271PIDR, Ungaro, et al., Lancet 2017; Chi, Cell & Mol Immuno 2022 The UC Inflammation Cycle Immune Imbalance Epithelial Disruption Mucosal Inflammation Anti-Inflammatory Pro-Inflammatory


Slide 9

Bimodal Targeting of the Intracellular Environment & Extracellular Inflammatory Response Aims to Control Multiple Factors in the UC Inflammation Cycle O’Neill et al. Nat. Rev. Immunol. 2016; Bittencourt et al. Inflammm Bowel Dis 2021; Chi, Cell & Mol Immuno 2022; ROS: Reactive Oxygen Species Metabolic State Extracellular signals are balanced in response to stimuli Pro-inflammatory cells use glycolysis to generate energy fast Anti-inflammatory cells use mitochondria to supply steady energy; control ROS generation Intracellular immunometabolic environment favors inflammatory cells Increased glycolysis promotes pro-inflammatory cells and cytokine release Intracellular immunometabolic environment favors balance Extracellular signals are inflammatory Maintenance of tight junctions and barrier Loss of epithelial cell health, tight junctions & barrier integrity Healthy Ulcerative Colitis Inflammation Healthy Dying cell Mucus layer Epithelium Mitochondrial deficiencies reduce anti-inflammatory cells; ROS accumulate


Slide 10

NX-13 Bimodal MOA Addresses Both Extracellular Signals and Intracellular Environment to Reduce UC Inflammation Cycle Leber et al. J Immunology 2019; Leber et al. Front. Immuno 2018 Broad immune balance disfavors pro-inflammatory cells and cytokines with enhanced anti-inflammatory control Improved epithelial barrier integrity to reduce exposure to inflammatory microbes Decreased low grade mucosal inflammation and microbiome dysbiosis NX-13 is designed to shift the underlying intracellular immunometabolic environment of immune cells: Increases mitochondrial metabolism Upregulates antioxidant enzymes Decrease ROS Decreases Inflammasome activation NX-13 is designed to modulate the extracellular response: Reduces inflammatory cell differentiation Reduces TNFα, IFNγ, IL-17, IL-1.
