For production of Cvac, each patient's cells were enriched using cell separation techniques. The patient's cells were cultured for 5 days with granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) in AIM V® serum-free tissue culture medium (Thermo Fisher Scientific) to cultivate the growth of dendritic cells (DC). The culture was pulsed overnight with the antigen (mannosylated mucin 1 fusion protein [M-FP]) to arm the DCs to the specific mucin 1 antigen. After harvesting, the M-FP-pulsed DCs were formulated as a finished product (Cvac) in 1 mL aliquots, diluted in 5% human serum albumin (HSA) and 10% dimethyl sulfoxide (DMSO) at an approximate concentration of 60 × 10^6 viable DCs/mL. The vials were cryopreserved and stored in the vapor phase of liquid nitrogen at the manufacturing facility.
