CMV-DCs With GM-CSF and Td (Tetanus Toxoid)
CMV-DCs are autologous dendritic cells derived from peripheral blood mononuclear cells (PBMCs) loaded with ribonucleic acid (RNA) encoding the human CMV matrix protein pp65 as a fusion protein with the full-length LAMP protein (pp65-flLAMP) plus GM-CSF and Td vaccine as adjuvants.

Percentage of Patients for Whom 3 or More Vaccines Can be Made
90.9 percentage of participants
Interval 58.7 to 99.8

PRIMARY outcome

Timeframe: 1 year

Population: One eligible patient had a leukapheresis (evaluable for feasibility), but was withdrawn from the study due to clinical decline prior to receiving any treatment (not evaluable for safety).

Percentage of patients who experience unacceptable toxicity from CMV-DC administration
