Landos Biopharma, Inc. (NASDAQ: LABP), a clinical-stage biopharmaceutical company utilizing its LANCE® Advanced A.I. platform to discover and develop novel therapeutics for patients with autoimmune diseases, today announced financial results for the third quarter ended September 30, 2021 and provided a corporate update on its clinical development plans.

“Landos is well-positioned to continue its evolution as a biopharmaceutical company. In parallel with our search for Landos’ next leader, our Board, leadership team and advisors are reviewing our product development strategies and clinical plans to ensure that we are focusing on the most value-enhancing near-and long-term opportunities,” said Tim Mayleben, Interim President and CEO of Landos. “Landos has already established itself as a research and discovery leader based on the productivity of the LANCE Advanced A.I. platform. Leveraging that success, we are taking steps to evaluate and optimize our product development and clinical strategies, and we will be prioritizing our three clinical-stage product candidates, omilancor, NX-13, and LABP-104, and concentrating on the immune-mediated inflammatory disease indications of ulcerative colitis, Crohn’s disease, Eosinophilic Esophagitis, Systemic Lupus Erthematosus, and Rheumatoid Arthritis. In addition, we will be reviewing our preclinical programs to optimize the priorities and sequence of these product candidates and their respective clinical applications. We believe that narrowing our focus on advancing our core, high-impact clinical-stage programs will support the strongest outcomes for these product candidates and best position Landos for regulatory approval and commercial success in the future. We look forward to providing continued updates on our progress and deliver value for patients and our shareholders.”

Clinical Development Updates

Omilancor

Omilancor is a novel, oral, gut-restricted LANCL2 agonist in development for the treatment of ulcerative colitis (UC), Crohn’s disease (CD) and Eosinophilic Esophagitis (EoE) as a once-daily oral treatment.

• In October 2021, Landos presented positive translational data from the Phase 2 trial of omilancor in mild-to-moderate UC at United European Gastroenterology Week (UEGW). Patients remaining on omilancor after the induction phase of the trial maintained low Mayo scores and showed little to no symptoms beyond 1 year of treatment, with nearly 90% of patients achieving remission thresholds in stool frequency and rectal bleeding after 36 weeks of open-label treatment.
  
  
• Prior to initiating a pivotal Phase 3 study, Landos plans to leverage the results of the prior Phase 2 study of omilancor in mild-to-moderate UC patients to design and initiate a Phase 2b study in 2022. The Phase 2b study is expected to provide additional data to inform the pivotal Phase 3 study design and support regulatory approval.
  
  
• Enrollment in the Phase 2 trial of omilancor in moderate-to-severe CD continues. Landos is actively evaluating the sample size to ensure the Company optimizes the powering of its data. Given the ongoing evaluation, Landos is removing prior guidance for the timing of top-line results.
  
  
• Landos plans to file an orphan drug designation application for pediatric UC patients in Q4 2021.

NX-13

NX-13 is a novel, oral, gut-restricted NLXR1 agonist in development for the treatment of UC and CD as a once-daily oral treatment.

• In October 2021, Landos presented results of its Phase 1a trial of NX-13 in healthy volunteers at UEGW 2021. The trial met all primary and secondary endpoints. The data also demonstrated a signal of efficacy in terms of lowering fecal calprotectin levels, increasing IL-10 concentrations and decreasing IL-6 concentrations in plasma.
  
  
• Enrollment in the Phase 1b trial of NX-13 in the U.S. and Europe continues. Landos is actively evaluating the sample size to ensure the Company optimizes the powering of its data. Given the ongoing evaluation, Landos is removing prior guidance for the timing of top-line results.

LABP-104

LABP-104 is a novel, oral, systemically distributed LANCL2 agonist in development for the treatment of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) as a once-daily oral treatment. LABP-104 activates the LANCL2 pathway to restore the immune system to homeostasis through the enhancement of regulatory T cell (Treg) function and increasing mitochondrial metabolism.

• In September 2021, Landos announced that the preclinical results of LABP-104 in SLE were accepted for an oral presentation at the American College of Rheumatology Convergence 2021 in November. The presentation will highlight how oral treatment with LABP-104 resulted in enhanced Treg function, maintained kidney function and reduced type I interferon signaling.
  
  
• Landos received FDA clearance in October 2021 of an IND for LABP-104 for the treatment of SLE and RA. A Phase 1 trial has been initiated to evaluate the safety, tolerability and pharmacokinetics of LABP-104 in healthy volunteers. Top-line results from this study are expected in 1H 2022.

Summary of Third Quarter 2021 Financial Results

Cash, Cash Equivalents and Marketable Securities:

As of September 30, 2021, the Company had cash, cash equivalents and marketable securities of $102.7 million, which it believes will be sufficient to fund planned operations through the end of 2023.

Research and Development ("R&D") Expenses:

Research and development expenses were $9.3 million for the three months ended September 30, 2021 compared to $7.0 million for the three months ended September 30, 2020. The increase of $2.3 million was primarily attributable to increased costs associated with ongoing development activities related to omilancor, NX-13 and LABP-104.

General and Administrative ("G&A") Expenses:

General and administrative expenses were $3.1 million for the three months ended September 30, 2021 compared to $1.5 million for the three months ended September 30, 2020. The increase of $1.6 million was primarily attributable to increases in D&O insurance costs and administrative expenses related to increased headcount.

Other Income (Expense):

Other expense, net was $0.2 million for the three months ended September 30, 2021 compared to other income, net of $0.2 million in the three months ended September 30, 2020. The change of $0.4 million was due to amortization of bond premium from investment activity and the gains (losses) from foreign exchange.
