MIAMI, March 09, 2026 (GLOBE NEWSWIRE) -- SAB Biotherapeutics, Inc. (NASDAQ:SABS), a clinical-stage biopharmaceutical company developing human anti-thymocyte immunoglobulin (hATG) for type 1 diabetes (T1D) and other autoimmune diseases, today announced financial results for the full year 2025 and provided business highlights.
"2025 marked an important year of execution for SAB. We delivered Phase 1 clinical data for SAB-142, completed a $175 million oversubscribed financing with high quality investors including Sanofi, and advanced SAB-142 into our registrational Phase 2b SAFEGUARD study with the first patient dosed," said Samuel J. Reich, CEO, SAB BIO. "In 2026, our focus is on enrolling SAFEGUARD. We are encouraged by current momentum and remain on track to complete enrollment by year end with topline data expected in the second half of 2027. We also expect to share additional Phase 1 data and support the initiation of an investigator led study as we continue to build the clinical foundation for SAB-142 in T1D."
Recent Pipeline Achievements and Anticipated Milestones for SAB-142
Phase 2b SAFEGUARD Study
- Initiated and dosed multiple patients in the SAFEGUARD (SAFety and Efficacy of human anti-thymocyte immunoGlobUlin SAB-142 ARresting progression of type 1 Diabetes) clinical trial of SAB-142 as a novel, potentially best-in-class, disease-modifying immunotherapeutic approach in development to treat T1D by delaying the progression of disease.
- Activated multiple clinical trial sites in the U.S., Australia, and New Zealand.
- On May 29, 2025, the Company held a constructive Type B meeting with the U.S. Food and Drug Administration (FDA).
- The FDA provided guidance leading to alignment on the design and advancement of our Phase 2b SAFEGUARD study.
- SAB confirmed its intent with the FDA to utilize the data from the SAFEGUARD study as supportive evidence for future regulatory approval.
- Enrollment is ongoing and the Company is on track to complete enrollment in SAFEGUARD by the end of 2026 with topline data expected in 2H 2027.
Phase 1 Data in Healthy Volunteer, Redosing, and T1D Cohorts
- Reported positive confirmatory clinical results from the Phase 1 study of SAB-142 in healthy volunteers, redosing, and T1D cohorts in December 2025.
- Data confirmed SAB-142 does not cause serum sickness and has low/no immunogenicity at any dose and in all cohorts, including redosed healthy volunteers.
- Transient lymphopenia, an on-target marker of target engagement and pharmacodynamic activity, was observed after dosing and rapidly corrected to baseline within 1-3 days in all participants.
- The lack of sustained lymphodepletion observed supports the chronic dosing of SAB-142 in an outpatient setting for the treatment of Stage 3 autoimmune type 1 diabetes.

About SAB-142
SAB-142 is a potentially disease-modifying, redosable immunotherapy in clinical development for the treatment of autoimmune type 1 diabetes (T1D). SAB-142 is a multi-specific, fully human anti-thymocyte globulin (hATG) with a mechanism of action
analogous to that of rabbit ATG (rATG). rATG has demonstrated in multiple clinical trials the ability to slow disease progression in patients with new- or recent-onset of Stage 3 T1D. SAB-142, like rATG, directly targets multiple immune cells involved in destroying pancreatic beta cells, including modulation of "bad acting" T-lymphocytes. By stopping immune cells from attacking beta cells, this treatment has the potential to preserve insulin-producing beta cells.
About SAB BIO
SAB BIO is a clinical-stage biopharmaceutical company focused on developing multi-specific, high-potency, human immunoglobulin G (hIgG) to treat and prevent immune and autoimmune disorders. Using advanced genetic engineering and antibody science, SAB BIO developed a proprietary technology which holds the potential to generate additional novel therapeutic candidates utilizing the human immune response, without the need for human donors or convalescent plasma. SAB BIO has optimized genetic engineering in the development of transchromosomic cattle, or Tc-Bovine™, to produce hIgG. SAB BIO's drug development production system is able to generate a diverse repertoire of specifically targeted, high-potency hIgGs that can address a wide range of serious unmet needs in human diseases. The Company's lead candidate, SAB-142, targets autoimmune T1D with a disease-modifying therapeutic approach that aims to change the T1D treatment paradigm by delaying onset and potentially preventing disease progression of Stage 3 T1D patients. SAB-142 is currently being evaluated in newly diagnosed Stage 3 autoimmune T1D patients in a registrational Phase 2b clinical trial called SAFEGUARD. For more information, visit www.sab.bio.
