About

Patients with Multiple myeloma who have undergone non-myeloablative allogeneic stem cell transplant will receive 6 vaccinations of donor derived dendritic cells combined with specific protein produced by multiple myeloma.

Full description

To evaluate feasibility and safety of vaccination with allogeneic idiotype-pulsed dendritic cells following mixed chimeric allogeneic transplantation for multiple myeloma.

Enrollment: 30 estimated patients

Sex: All

Ages: 17 to 70 years old

Volunteers: No Healthy Volunteers
