AlloStim is combination biological drug and medical device formulation consisting of allogeneic immune cells that have been expanded and differentiated ex-vivo. These cells are conjugated to monoclonal antibody coated microparticles prior to infusion. The immune cells are living CD4+ memory Th1-like T-cells (T-Stim) that are differentiated from precursors purified from normal donor blood. AlloStim is a composition of T-Stim cells conjugated to paramagnetic epoxy covered microparticles (4.5micron) with covalently bound anti-CD3/anti-CD28 monoclonal antibodies (Dynabeads® ClinExVivo™ CD3/CD28) at a 2:1 bead:cell ratio. The T-Stim cells are intentionally mismatched to the recipient.
