The Company’s lead product candidate, SAB-142, is a human anti-thymocyte globulin (ATG) focused on preventing or delaying the progression of T1D. SAB-142 is expected to reduce autoimmune beta cell destruction and delay progression or onset of T1D in patients with Stage III or Stage II T1D. The Company’s genetic engineering platform produces human, multi-targeted, high-potency immunoglobulins, without the need for human donors or convalescent plasma.
