Landos Biopharma Provides Business Update and Reports Fourth Quarter and Full Year 2023 Results

Top-line Results from the NEXUS Phase 2 Clinical Trial of NX-13 for Ulcerative Colitis Planned for Q4 2024

Sufficient Cash to Fund Planned Operations into mid-2025

NEW YORK, March 21, 2024 (GLOBE NEWSWIRE) — Landos Biopharma, Inc. (NASDAQ: LABP) (“Landos” or “the Company”), a clinical-stage biopharmaceutical company developing novel, oral medicines for patients with autoimmune diseases, today provided a business update and reported financial results for the fourth quarter and the full year ended December 31, 2023.

“We were focused in 2023 on advancing the NX-13 clinical program and establishing Landos as a leader in targeting immunometabolic pathways and developing novel and first-in-class, oral therapies for autoimmune diseases,” said Gregory Oakes, President and CEO of Landos. “We continue to advance the NEXUS Phase 2 study of NX-13 in ulcerative colitis and are excited about the strong momentum we have generated.”

Fourth Quarter 2023 and Recent Highlights

• NEXUS is a Phase 2 proof-of-concept clinical trial of NX-13, a novel, gut-selective NLRX1 agonist, in development as a once-daily, oral treatment for ulcerative colitis (“UC”).
  • The Company continues to recruit, screen and randomize patients for the trial in the United States and Europe, with 28 sites activated to date.
  • NEXUS, evaluating the clinical efficacy, safety and pharmacokinetics of oral NX-13, is a randomized, 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 are randomized to receive either a 250 mg or 750 mg immediate release dose of NX-13 or placebo (NCT05785715).
  • Top-line results are planned for the fourth quarter of 2024.

• In October 2023, the Company presented two oral presentations and one poster at the United European Gastroenterology Week (UEGW) and three posters at the American College of Gastroenterology (ACG) 2023 Annual Scientific Meeting. These presentations included additional findings from the Phase 1b study of NX-13 for the treatment of UC, including detailed results on the rapid symptomatic relief and improvement in multiple biomarkers observed in the study.
• In November 2023, a peer-reviewed manuscript describing the safety, tolerability, pharmacokinetic and clinical efficacy results for the NX-13 Phase 1b trial in patients with UC was published in the Journal of Crohn’s and Colitis.
• In February 2024, the Company presented six abstracts at the 19th Annual Congress of the European Crohn’s and Colitis Organisation (ECCO) in Stockholm, Sweden. These poster presentations highlighted new and additional data on immunometabolism modulation by activating NLRX1 and PLXDC2 with novel agonists such as NX-13 and LABP-69.

Summary of Fourth Quarter and Full Year 2023 Financial Results

Cash and Cash Equivalents

• As of December 31, 2023, the Company had cash and cash equivalents of $37.5 million, which it believes will be sufficient to fund planned operations into mid-2025.

Fourth Quarter 2023

• Research and development expenses were $3.1 million for the fourth quarter of 2023, compared to $3.4 million for the fourth quarter of 2022. The decrease was primarily attributable to reduced clinical activities due to the wind down of the omilancor and LABP-104 programs and a reduction in NX-13 Phase 1b clinical trial expenses, partially offset by the initiation of the NX-13 Phase 2 trial.
• General and administrative expenses were $3.5 million for the fourth quarter of 2023, compared to $3.1 million for the fourth quarter of 2022. The increase was primarily attributable to an increase in legal expenses, partially offset by a decrease in insurance and compensation expenses.

Full Year 2023

• Research and development expenses were $12.0 million for the full year ended December 31, 2023, compared to $25.7 million for the full year ended December 31, 2022. The decrease was primarily attributable to reduced clinical activities due to the wind down of the omilancor and LABP-104 programs and a reduction in NX-13 Phase 1b clinical trial expenses, partially offset by the initiation of the NX-13 Phase 2 trial.
• General and administrative expenses were $10.7 million for the full year ended December 31, 2023, compared to $14.9 million for the full year ended December 31, 2022. The decrease was primarily attributable to a decrease in compensation, insurance, and consulting expenses, partially offset by an increase in legal expenses.
