AUSTIN, TX and DURHAM, NC, Aug. 14, 2025 (GLOBE NEWSWIRE) -- Shattuck Labs, Inc. (Shattuck or the Company) (NASDAQ: STTK), a biotechnology company pioneering the development of novel therapeutics targeting tumor necrosis factor (TNF) superfamily receptors for the treatment of patients with inflammatory and immune-mediated diseases, today reported financial results for the second quarter ended June 30, 2025 and provided recent business highlights.

“The second quarter of 2025 was a productive period for Shattuck, as we prepared and successfully submitted an IND application to the U.S. Food & Drug Administration (FDA),” said Taylor Schreiber, M.D., Ph.D., Chief Executive Officer of Shattuck. “We expect to begin enrollment in our Phase 1 clinical trial, subject to regulatory alignment, in healthy volunteers later this quarter, and to complete the trial during the second quarter of 2026. Following our recent private placement, led by OrbiMed, we are in a strong position and expect to transition seamlessly into multiple Phase 2 clinical trials for our lead asset, SL-325, and fund our operations into 2029.”

DR3 Program Development in 2025

Shattuck’s lead product candidate, SL-325, is a potentially first-in-class DR3 blocking antibody for the treatment of IBD and other inflammatory and immune-mediated diseases. Recent updates and anticipated upcoming milestones for SL-325 include:
An IND was submitted to the FDA for SL-325 in July 2025; clearance expected in the third quarter of 2025.
Phase 1 clinical trial will evaluate safety, tolerability, immunogenicity and pharmacokinetics in healthy volunteers, and determine the recommended Phase 2 dose and dosing schedule of SL-325. Subject to regulatory alignment, dosing of the first participant in the single-ascending dose (SAD) portion of the trial is expected in the third quarter of 2025, and the multiple-ascending dose (MAD) portion of the trial is expected to commence in the fourth quarter of 2025.
Phase 1 enrollment of the SAD and MAD portions of the clinical trial is expected to be completed in the second quarter of 2026.
Shattuck continues to develop multiple preclinical DR3-based bispecific antibodies, which are designed to inhibit both the DR3/TL1A axis and other biologically relevant targets for the treatment of patients with IBD. Shattuck plans to nominate a lead bispecific candidate from its preclinical pipeline in 2025.

Financial Guidance

As of June 30, 2025, cash and cash equivalents were approximately $50.5 million, which does not include the anticipated net proceeds from the private placement announced on August 5, 2025. The total anticipated proceeds from the oversubscribed private placement of up to approximately $103 million, less offering expenses, combined with current cash and cash equivalents, are expected to fund operations into 2029. The closing of the private placement is contingent upon the IND clearance for SL-325 and the satisfaction of other customary closing conditions. Shattuck intends to use the anticipated net proceeds from the private placement (including the potential proceeds to be received upon the full exercise of the accompanying common stock warrants) for the clinical development of SL-325, including multiple Phase 2 clinical trials in Inflammatory Bowel Disease (IBD) and potentially another autoimmune disease, and for general corporate purposes. This cash runway guidance is based on the Company’s current operational plans and excludes any additional capital that may be received, proceeds from business development transactions, and/or additional costs associated with clinical development activities that may be undertaken.

About SL-325

SL-325 is a potential first-in-class Death Receptor 3 (DR3) blocking antibody designed to achieve a complete and durable blockade of the clinically validated DR3/TL1A pathway. Shattuck’s preclinical studies demonstrate high affinity binding and superior activity over TL1A antibodies, and offer a data-driven rationale for targeting the TNF receptor, DR3, versus its ligand, TL1A. Shattuck expects to commence a Phase 1 clinical trial in healthy volunteers in the third quarter of 2025.
