On Track to Initiate Phase 2 Proof-of-Concept Trial in Ulcerative Colitis for NX-13 in the Second Quarter of 2023 and Report Topline Results by the Fourth Quarter of 2024

Projected Cash Runway into First Half of 2025

NEW YORK, March 23, 2023 (GLOBE NEWSWIRE) — 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 fourth quarter and full year ended December 31, 2022.

“Meaningful progress has been made this year as we streamlined our product candidate portfolio to focus on our most promising asset. We believe Landos is uniquely positioned to transform the treatment paradigm for patients with ulcerative colitis with our novel, oral, once-daily treatment NX-13,” said Gregory Oakes, President and CEO of Landos. “Our capital efficient approach focuses resources towards advancing the clinical development of NX-13, while maximizing our ability to create value for our shareholders.”

NX-13 Clinical Development Updates
NX-13 is a novel, gut-selective NLXR1 agonist in development as a once-daily, oral treatment for ulcerative colitis (UC).

• In August 2022, the Company announced top-line results from the Phase 1b trial in patients with UC with early signals of clinical improvement as soon as two weeks in patients’ symptoms and four weeks by endoscopy in exploratory endpoints. Favorable safety and tolerability was shown across a range of doses.
• Pharmacokinetic (PK) and Pharmacodynamic (PD) data preliminary analyses demonstrated promising signals of target engagement and molecular dose response among 250 mg and 500 mg immediate release doses.
• Next Steps: Our Phase 2 proof-of-concept clinical trial remains on-track for initiation in the second quarter of 2023, with plans to share topline results by the fourth quarter of 2024.

Corporate Updates

• Updated clinical development strategy to focus exclusively on the NX-13 UC program, following a comprehensive review of the entire portfolio to ensure we are pursuing the most promising therapies and target indications.
• Secured $16.7 million in funding from Landos’ largest shareholder, Perceptive Advisors, through the sale of prefunded warrants.
• Announced the transfer of the LANCL portfolio, including omilancor, LABP-104 and LABP-111, to Landos’ founder and former CEO and certain affiliated individuals and entities. Under the terms of the transaction, the Company transferred the assets and paid $3.0 million in cash in exchange for approximately 9.1 million Landos shares previously held by Dr. Bassaganya-Riera and certain affiliated individuals and entities, representing approximately 23% of Landos’ outstanding shares. Additionally, the parties have entered into a royalty agreement whereby Landos will receive a 6% royalty on future commercial net sales from any approved products developed from the LANCL portfolio and Dr. Bassaganya-Riera and certain affiliated individuals and entities will receive a 2% royalty on future net sales from NX-13, LABP-73, LABP-66 and LABP-69, if approved. The parties have also agreed to a mutual, general release of liabilities and claims.

Summary of Fourth Quarter and Full Year 2022 Results

Cash, Cash Equivalents and Marketable Securities:

• We believe that our existing cash, cash equivalents and marketable securities as of December 31, 2022, in addition to the $16.7 million in gross proceeds from our private placement of pre-funded warrants in January 2023, will be sufficient to fund our operating expenses and capital requirements into the first half of 2025.

Quarter Ended December 31, 2022

• Research and development expenses were $3.4 million for the quarter ended December 31, 2022, compared to $13.4 million for the quarter ended December 31, 2021. The decrease was primarily attributed to reduced clinical activities due to the wind down of omilancor and LABP-104-related clinical trials, as well as decreases in employee-related expenses.
• General and administrative expenses were $3.1 million for the quarter ended December 31, 2022, compared to $7.0 million for the quarter ended December 31, 2021. The decrease was primarily attributable to a decrease in consulting costs, employee-related expenses and office-related expenses.

Year Ended December 31, 2022

• Research and development expenses were $25.7 million for the full year ended December 31, 2022, compared to $41.6 million for the full year ended December 31, 2021. The decrease was primarily attributed to reduced clinical activities due to the wind down of omilancor and LABP-104 related clinical trials, as well as decreases in employee-related expenses, partially offset by increases in costs associated with the clinical development of NX-13.
• General and administrative expenses were $14.9 million for the full year ended December 31, 2022, compared to $15.3 million for the full year ended December 31, 2021. The decrease was primarily attributable to a reduction in consulting costs and office-related expenses.
