Rhea-AI Filing Summary
SAB Biotherapeutics, Inc. filed a current report describing a new grant-funded clinical study of its lead candidate SAB-142 in type 1 diabetes. Breakthrough T1D has awarded a grant to support the PRISE‑hATG trial, led by Dr. Michael J. Haller at the University of Florida.
The PRISE‑hATG study will evaluate SAB‑142 in patients with Stage 3 type 1 diabetes who are between 100 days and two years from diagnosis, a group that typically falls outside earlier-stage trials. SAB BIO will co-fund the trial, which is designed to assess whether SAB‑142 can preserve C‑peptide and modulate immune responses. The study complements SAB BIO’s ongoing Phase 2b SAFEGUARD trial of SAB‑142 in newly diagnosed Stage 3 patients.

Stage 3 T1D medical
"Stage 3 T1D is diagnosed when the disease has progressed to a point where insulin is required."
C-peptide medical
"The PRISE-hATG study is designed to assess whether SAB‑142 can preserve endogenous C‑peptide and modulate immune responses."
C‑peptide is a short protein fragment released at the same time the pancreas produces insulin; because it lingers in the blood longer than insulin itself, clinicians measure C‑peptide levels as a clear sign of how much natural insulin a person still makes. For investors, C‑peptide matters because it’s used as a measurable outcome in diabetes drug and device trials, in diagnostic tests, and by regulators to judge treatment benefit — results that can affect clinical success, approvals, and market value.
Phase 2b SAFEGUARD trial medical
"It extends SAB BIO’s clinical evaluation of SAB‑142 and complements the ongoing Phase 2b SAFEGUARD trial evaluating SAB‑142 in patients with new onset Stage 3 T1D."
anti-thymocyte globulin (hATG) medical
"SAB-142 is a multi-specific, fully human anti-thymocyte globulin (hATG) with a mechanism of action analogous to that of rabbit ATG (rATG)."
transchromosomic cattle technical
"SAB BIO has optimized genetic engineering in the development of transchromosomic cattle, or Tc-Bovine, to produce hIgG."
FAQ
What did SAB Biotherapeutics (SABS) disclose in this 8-K filing?
SAB Biotherapeutics disclosed that Breakthrough T1D awarded a grant to support the PRISE‑hATG clinical study of SAB‑142 in Stage 3 type 1 diabetes, and that SAB BIO will co-fund this investigator-led trial, which complements its ongoing Phase 2b SAFEGUARD study.
What is the PRISE-hATG study mentioned by SAB Biotherapeutics (SABS)?
PRISE‑hATG is a randomized, double-blind, placebo-controlled clinical study evaluating SAB‑142 in Stage 3 type 1 diabetes patients diagnosed more than 100 days and up to two years earlier. It is designed to assess safety, efficacy, tolerability, and preservation of endogenous C‑peptide using harmonized methods with the SAFEGUARD trial.
Who is funding the new SAB-142 PRISE-hATG trial for SAB Biotherapeutics (SABS)?
Breakthrough T1D has awarded a grant to support the PRISE‑hATG trial, and SAB Biotherapeutics will co-fund the study. The trial is investigator-led by Dr. Michael J. Haller at the University of Florida and focuses on Stage 3 type 1 diabetes patients beyond 100 days from diagnosis.
What is SAB-142, the lead candidate highlighted by SAB Biotherapeutics (SABS)?
SAB‑142 is a potentially disease-modifying, redosable immunotherapy in development for autoimmune type 1 diabetes. It is a multi-specific, fully human anti-thymocyte globulin designed to target immune cells that destroy pancreatic beta cells, with the aim of preserving insulin-producing cells and slowing disease progression.
How does the PRISE-hATG study relate to SAB Biotherapeutics’ SAFEGUARD trial?
PRISE‑hATG extends SAB‑142 clinical evaluation to Stage 3 type 1 diabetes patients 100 days to two years from diagnosis, while SAFEGUARD is a registrational Phase 2b trial in newly diagnosed Stage 3 patients. Sampling and analytical methods are harmonized to enable cross‑cohort comparisons between the two studies.
What is Breakthrough T1D’s role in the SAB Biotherapeutics (SABS) program?
Breakthrough T1D, a leading global type 1 diabetes research and advocacy organization, awarded a grant to support the PRISE‑hATG study of SAB‑142. It partners with Dr. Haller and SAB BIO to advance disease‑modifying therapies for Stage 3 type 1 diabetes patients beyond the first 100 days after diagnosis.
