SAB Biotherapeutics, Inc. (NASDAQ: SABS) shares sprinted Tuesday. The Miami-Beach company, a clinical-stage biopharmaceutical concern 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 their Chief Medical Officer, Dr. Alexandra Kropotova, MD, MBA disclosed that SAB has completed dosing the third cohort for SAB-142 with no observation of serum sickness thus far.
In October 2023, SAB received approval by the Australian Human Research Ethics Committee (HREC) to commence the Phase 1 clinical trial investigating safety, tolerability, pharmacokinetic, pharmacodynamic, and immunogenicity of SAB-142. The primary objective of the trial is two-fold: 1) to generate data on differentiated safety and immunogenicity of this human immunoglobulin, and 2) to establish a Proof of Biological Activity (POBA) for SAB-142.
Phase 1 of SAB-142 is a randomized, double-blind, placebo-controlled, single-ascending dose, adaptive design clinical study was designed to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of intravenous SAB-142 in healthy volunteers and participants with T1D. SAB-142 is a first-in-class human anti-thymocyte immunoglobulin being developed as a disease-modifying treatment to delay the onset and progression of T1D.
SAB-142 is a human alternative to rabbit anti-thymocyte globulin (ATG). SAB-142’s mechanism of action is analogous to that of rabbit ATG, which has been clinically validated in multiple clinical trials for type 1 diabetes.
Shares in SABS began Tuesday up 33 cents, or 7.2%, to $4.94.
