AlloStim® In-Situ Vaccine in Pre-Treated Metastatic Colorectal Cancer

AlloStim® is derived from the blood of normal blood donors and is intentionally mismatched to the recipient. CD4+ T-cells are separated from the blood and differentiated and expanded for 9-days in culture to make an intermediary called T-Stim.

The syringes are shipped refrigerated to the point-of-care.
