"2023 was a transformative year for Palisade Bio as we strategically shifted into the autoimmune, inflammatory, and fibrotic disease space, with the focus on our precision medicine approach in inflammatory bowel disease," commented J.D. Finley, Chief Executive Officer. "As a result of the progress made by our development team, we are on track to launch the Phase 1 study of PALI-2108 by the end of 2024. We are looking forward to the advancement of our lead program to bring our product candidates into clinical trials and to increase our value for all stakeholders."

PALI-2108 Development Program

The Company continues to advance its lead program, PALI-2108, for the treatment of moderate-to-severe ulcerative colitis (UC) toward a Phase 1 clinical study. PALI-2108 is an orally administered, locally acting colon-specific phosphodiesterase-4 (PDE4) inhibitor prodrug in development for patients affected by UC.

Upcoming Target Milestones

• Complete ongoing IND/CTA-enabling tox studies by the end of the second quarter of 2024;
• Complete nonclinical IND/CTA-enabling activities by the end of the third quarter of 2024;
• Submit initial IND/CTA prior to the end of 2024; and
• Initiate Phase 1a/b prior to the end of 2024.

Precision Medicine Approach

Additionally, the Company is in the process of developing a genetic- or biomarker-based precision medicine approach that, if developed, will aid patients and physicians in selecting patients most likely to respond to PDE4 inhibitor therapy with PALI-2108. The Company is working with a strategic collaborator on development and has completed curation of a pipeline including over 1600 UC patients clinical and biomarker data and is in ongoing discussions with potential partners with access to additional patient data to support development of an FDA-approved test. The Company plans to leverage this expertise and infrastructure to fuel a growing pipeline of validated and high-priority autoimmune, inflammatory, and fibrotic disease product candidates.

Summary of Financial Results for the Year Ended December 31, 2023

As of December 31, 2023, the Company had cash, cash equivalents and restricted cash of $12.5 million. The Company believes it has sufficient cash to fund its currently planned operations into the first quarter of 2025.

Net operating loss was $13.1 million for the year ended December 31, 2023 compared to $15.7 million for the year ended December 31, 2022. Included in the net operating loss for the year ended December 31, 2023 was license revenue of $0.3 million, of which there was none in 2022, and restructuring costs of $0.2 million in 2023, compared to restructuring costs of $0.4 million in 2022.

Research and development expenses were $6.9 million for the year ended December 31, 2023, an increase of $0.3 million, or approximately 5% compared to the year ended December 31, 2022. The year-over-year increase is attributable to increased costs associated with the Giiant License Agreement, which we entered into on September 1, 2023, as well an increase in employee-related costs and employee recruiting costs, which were partially offset by a decrease in costs directly related to our development of LB1148, which we ceased in August of 2023.

General and administrative expenses decreased from $8.8 million for the year ended December 31, 2022 to $6.2 million for the year ended December 31, 2023. The decrease of $2.6 million, or 26%, was primarily as a result of cost-saving opportunities implemented by us in the third and fourth quarters of 2022, including those associated with the 2022 Cost-Reduction Plan. General and administrative employee compensation costs for the year ended December 31, 2023 decreased by approximately $1.4 million compared to the year ended December 31, 2022, primarily due to an approximately $0.9 million decrease in salaries and benefits and an approximately $0.5 million decrease in stock-based compensation expense. Other decreases in general and administrative expenses for the year ended December 31, 2023 compared to the year ended December 31, 2022 include: (i) an approximately $0.3 million decrease in professional fees, including accounting and legal fees and financial printing costs, (ii) an approximately $0.3 million decrease in investor and public relations costs and shareholder services costs, (iii) an approximately $0.2 million decrease in consultants and contract labor costs, (iv) an approximately $0.2 million decrease in general and administrative employee recruiting costs, and (v) an approximately $0.2 million decrease in insurance costs.
