– Company advances SL-325 program with an IND filing expected in the third quarter of 2025 –
– Cash balance of approximately $60.9 million as of March 31, 2025, expected to fund operations into 2027 –
AUSTIN, TX and DURHAM, NC, May 01, 2025 (GLOBE NEWSWIRE) — Shattuck Labs, Inc. (Shattuck) (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 first quarter ended March 31, 2025 and provided recent business highlights.
“All IND-enabling activities and regulatory interactions remain on-track to initiate the Phase 1 clinical trial for SL-325 in the third quarter of this year. We believe SL-325 is fundamentally differentiated in its approach to targeting the clinically validated DR3/TL1A pathway and could potentially provide best-in-class clinical remission rates for IBD patients,” said Taylor Schreiber, M.D., Ph.D., Chief Executive Officer of Shattuck. “Spending last quarter continued to come in line with expectations, and wind-down activities associated with the discontinued oncology programs have now been substantially completed. We continue to be well-positioned to fund operations into 2027, beyond the results from our Phase 1 clinical trial for SL-325.”
DR3 Program Development in 2025
- Shattuck’s lead product candidate, SL-325, is a potentially first-in-class DR3 antagonist antibody. SL-325 is a DR3 blocking antibody for the treatment of IBD and other inflammatory and immune-mediated diseases.
- IND filing expected in the third quarter of 2025.
- Phase 1 clinical trial will evaluate safety, tolerability, and pharmacokinetics, and determine the recommended Phase 2 dose and dosing schedule of SL-325. First patient in for the SAD portion of the trial expected in the third quarter of 2025.
- Phase 1 enrollment completion expected 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 another biologically relevant target for the treatment of patients with IBD. Shattuck plans to nominate a lead bispecific candidate from its preclinical pipeline in 2025.
First Quarter 2025 Business Highlights and Other Recent Developments
Recent Events
- Shattuck participated in the 24th Annual Needham Virtual Healthcare Conference on April 9, 2025. Taylor Schreiber, M.D., Ph.D., CEO of Shattuck Labs presented at the Conference. Details are on the Events & Presentations section of the Company’s website.
- Shattuck Labs participated in an oral presentation at ECCO in February 2025. Full press release can be found here. Presentation can be found here.
- Preclinical studies of SL-325 in NHP demonstrated a favorable safety profile with no infusion-related reactions observed, no changes in clinical pathology parameters, gross pathology, or histopathology analysis, and a No Observed Adverse Effect Level determined to be 100mg/kg, the top administered dose;
- Full receptor occupancy at 1 mg/kg or greater, durable for >28 days, no Treg expansion or activation of CD3 T cells observed; and
- Differentiation from TL1A blocking monoclonal antibodies may yield a distinct profile for bispecific antibody development. Notably, by targeting DR3, immune complex formation and stabilization of TL1A is not expected with SL-325, which may improve the immunogenicity profile as compared to TL1A targeting agents and allow for the development of DR3-based bispecific antibodies. Durable blockade of constitutively expressed DR3 may translate to higher complete remission rates.
- Shattuck Labs presented a poster at the 2025 Crohn’s & Colitis Foundation Congress in February. Poster can be found here.
- Data from in vitro preclinical development and characterization of SL-325 were presented.
- SL-325 is a fully Fc-silenced humanized immunoglobulin G monoclonal antibody that demonstrated high affinity binding to human DR3 and potent antagonistic properties with no evidence of residual agonism.
Upcoming Events
- Shattuck Labs to present at the PEGS Boston Summit on May 12, 2025. Taylor Schreiber, M.D., Ph.D., CEO of Shattuck Labs, will present on SL-325 in the Advances in Immunotherapy section of the conference. Details of the presentation will be on the Events & Presentations section of the Company’s website after the conclusion of the live event.
- Shattuck Labs to participate in the Leerink Partners Therapeutics Forum: I&I and Metabolism on July 8-9, 2025. Company management will participate in scheduled one-on-one investor meetings.

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. SL-325 has completed a GLP toxicology study in non-human primates, with an IND filing expected in the third quarter of 2025.
