Study Endpoints

Primary Endpoints

Area under the concentration-time curve (AUC) of C-peptide after a 2 hour mixed meal tolerance test (MMTT)
Dose administration to 12 Months

This is a measure of endogenous insulin production and β cell function (change from baseline in C-peptide ln \[AUC+1\].

Part A: Incidence of treatment-emergent adverse events (TEAEs), adverse events of special interest (AESIs), and serious adverse events (SAEs)
From dose administration through Week 4
Part B: Area under the concentration-time curve (AUC) of C-peptide after a 2 hour mixed meal tolerance test (MMTT)
From dose administration up to Month 12

This is a measure of endogenous insulin production and β cell function (change from baseline in C-peptide ln \[AUC+1\] at 12 months)

Part C: Area under the concentration-time curve (AUC) of C-peptide after a 2-hour mixed meal tolerance test (MMTT).
Baseline and Month 24

This is a measure of endogenous insulin production and β-cell function (change from baseline in C-peptide ln \[AUC+1\] at 24 months versus control).

Secondary Endpoints

AUC of C-peptide after a 2-hour MMTT in a priori in vitro identified "responders" and "non-responders"
Baseline, Months 3, 6, 9 and 12
Number of Participants With Treatment-Related Adverse Events as Assessed by CTCAE v5.0
Dose administration to 12 Months
To evaluate the pharmacokinetics (PK) of SAB-142
Days 1 and 2 of each treatment period (pre- and post-dose/end of infusion [EOI]), plus Week 1 for TP1 (for participants that attend the optional in-clinic visit), Week 4, and Months 3, and 7.

Frequently asked questions about SAB-142

What is SAB-142 used for?

SAB-142 is being developed for the treatment of Type 1 Diabetes. It is designed to interfere with the autoimmune process that destroys insulin-producing cells, with the goal of preserving endogenous C-peptide production in people with new, recent, or established onset Type 1 Diabetes.

What does SAB-142 target?

SAB-142 targets thymocytes, cells of the immune system that are central to T cell development and the autoimmune attack on pancreatic beta cells in Type 1 Diabetes. By acting on thymocytes, the drug is intended to blunt the immune-mediated destruction of insulin-producing cells.

Who is developing SAB-142?

SAB-142 is being developed by SAB Biotherapeutics, Inc., which trades on the Nasdaq under the ticker SABS. The company is running the clinical program for the asset in Type 1 Diabetes across multiple countries.

What phase is SAB-142 in?

SAB-142 is in Phase 3 development for Type 1 Diabetes. It is an investigational therapy and is not approved for commercial use. The program includes a Phase 3 study and a Phase 2 study, both of which are active, with a combined planned enrollment of 267 participants.

What clinical trials is SAB-142 in?

SAB-142 is being studied in two trials. NCT07670650, the PRISE study, is a Phase 3 trial in Type 1 Diabetes in the United States that is not yet recruiting, with planned enrollment of 108. NCT07187531 is a Phase 2 safety and efficacy trial that is recruiting across the United States, Europe, Australia, and New Zealand, with planned enrollment of 159.

Is SAB-142 the same as High Dose SAB-142?

Yes. High Dose SAB-142 is another name used for SAB-142, so searches for either term refer to the same investigational asset being developed by SAB Biotherapeutics for Type 1 Diabetes. Both names describe the same clinical program, which includes the Phase 3 PRISE study and a Phase 2 trial.
