  • SAB-142 was generally well-tolerated among healthy volunteers; data from Phase 1 trial confirms SAB-142 does not cause serum sickness or anti-drug antibodies at target dose

  • Study results support that SAB-142 is well-positioned for re-dosing in outpatient setting for type 1 diabetes

  • Results will be presented in an R&D webinar event today at 8:00 am ET; registration details below

MIAMI, Jan. 28, 2025 (GLOBE NEWSWIRE) -- SAB BIO (Nasdaq: SABS), (“SAB BIO” or the “Company”), a clinical-stage biopharmaceutical company with a novel immunotherapy platform that is developing human anti-thymocyte immunoglobulin (hIgG) for delaying the onset or progression of type 1 diabetes (T1D), today announced positive topline data from a Phase 1 trial of SAB-142 in a single-ascending dose among healthy volunteers. The study met its primary objectives related to safety and pharmacodynamic activity enabling SAB-142 to advance to Phase 2b clinical development.

“I am particularly excited with the analysis of the results of our Phase 1 trial, as it marks the successful achievement of another critical milestone for SAB-142,” stated Samuel J. Reich, Chairman and CEO of SAB BIO. “These data show clear and positive pharmacologic activity and strong safety profile for SAB-142, and underscore SAB-142’s potential to change the lives of people impacted by type 1 diabetes. With our initial study objectives met, we believe SAB-142 is now well-positioned to be a transformative therapy in autoimmunity by delaying the progression or onset of type 1 diabetes, and we look forward to advancing this product candidate into Phase 2b clinical development in 2025.”

Phase 1 Trial Summary Data

The SAB-142 Phase 1 trial was designed as a randomized, double-blind, placebo-controlled, single-ascending dose, adaptive design clinical study among healthy volunteers and one cohort of participants with T1D. The objectives include establishing the safety, tolerability, pharmacokinetic (PK), immunogenicity and pharmacodynamic (PD) profile for SAB-142. The topline results reported today showed the following outcomes among healthy volunteer cohorts:

  • Favorable Safety Profile: SAB-142 was generally well-tolerated and demonstrated a favorable safety profile that supports the chronic dosing of SAB-142 in an ambulatory setting.

    • The SAB-142 Phase 1 dose range was between 0.03mg/kg up to 2.5mg/kg, which demonstrated favorable safety profile based on the 0% reported serum sickness and anti-drug antibodies.

  • Sustained Immunomodulation: SAB-142 demonstrated a clinically validated multi-target MOA with sustained immunomodulation.

  • MoA Analogous to Rabbit ATG: The mechanism of action (MoA) of SAB-142 was shown to be analogous to rabbit ATG

    • The SAB-142 MoA was shown to be analogous to rabbit ATG across multiple parameters correlative to C-peptide preservation.
