SAB Biotherapeutics Doses First Patient in Phase 2b Clinical Trial for Type 1 Diabetes
MIAMI, December 18, 2025 (GLOBE NEWSWIRE) — SAB Biotherapeutics, Inc. (Nasdaq: SABS), a pioneering clinical-stage biopharmaceutical company, has announced the successful dosing of the first patient in its Phase 2b clinical trial, named SAFEGUARD. This landmark study aims to evaluate the safety and efficacy of SAB-142, a potential breakthrough treatment designed to modify the progression of stage 3 Type 1 diabetes (T1D).
Significance of the SAFEGUARD Trial
The SAFEGUARD trial, which stands for SAFety and Efficacy of human anti-thymocyte immunoGlobUlin SAB-142 ARresting progression of type 1 Diabetes, signifies a crucial step forward for SAB Biotherapeutics. As detailed by Dr. Alexandra Kropotova, Chief Medical Officer at SAB BIO, the initiation of this trial is pivotal in advancing their 'Beyond Insulin' vision. SAB-142 is a fully human biologic intended to selectively target immune cells involved in T1D while sparing others from damage, offering hope for a disease-modifying treatment.
Clinical Trial Details
The SAFEGUARD trial is structured as a double-arm, multi-center Phase 2b study, with ongoing participation from multiple international centers including the U.S., Australia, and New Zealand. Patients enrolled in the trial will receive two infusions of SAB-142 over six months. Following the completion of the study, all trial participants, including those in the placebo group, will have the opportunity to partake in a 12-month extension study.
- SAB-142: A novel immunotherapy aimed at treating autoimmune T1D.
- Study Parts:

About SAB-142 and its Mechanism
SAB-142 is an innovative anti-thymocyte immunoglobulin (hATG) that aims to serve as a disease-modifying therapy for autoimmune type 1 diabetes. Its mechanism closely resembles that of rabbit ATG (rATG), which has been shown in clinical trials to slow disease progression in patients with new-onset stage 3 T1D. SAB-142 works by targeting and modulating pathogenic immune cells that compromise the function of pancreatic beta cells, thereby preserving insulin-producing abilities.
Company Background: SAB Biotherapeutics
SAB Biotherapeutics is at the forefront of developing high-potency human immunoglobulin G (hIgG) therapeutics to address immune and autoimmune disorders. With a strong focus on changing the treatment landscape for T1D, the company employs advanced genetic engineering methodologies to create therapeutic candidates that do not require human donors or convalescent plasma. The proprietary Tc-Bovine™ technology allows SAB BIO to produce an array of specifically targeted, high-potency hIgGs.
Looking Ahead
As this clinical trial progresses, SAB Biotherapeutics is set to provide further updates in 2026. The company remains committed to its goal of pioneering innovative solutions in diabetes care and is expected to share Phase 2b data by the second half of 2027.
