Vaccination-Dendritic Cells With Peptides for Recurrent Malignant Gliomas

Subjects will receive four (4) injections of the vaccine into the lymph nodes. Injection is guided by ultrasonography. Subjects will receive the first cycle of vaccine in the right groin. Two weeks after the first vaccine, subjects receive the same vaccine at the left groin, followed by the 3rd and the 4th vaccines in the left and right armpits, respectively, with two-week intervals. Each injection contains 0.2cc (less than 1/20th of a teaspoon) of a saline solution containing the vaccine cell mixture.

This phase will begin at week 13. These subjects will be treated with additional vaccinations every 4 weeks to a maximum of 5 vaccine injections and, if poly-ICLC is available from the supplier starting on the day of the first additional vaccine and twice/week for 8 injections following each additional vaccine. If poly-ICLC supply is not available from the supplier, DC vaccines only will be given in the booster phases.

"At week 33, following the completion of 5 additional vaccines, if participants demonstrate stable disease or positive clinical response, if poly-ICLC supply is still available, participants will be offered additional DC-vaccines and poly-ICLC treatment. The second phase booster vaccines can be continued as long as the patient shows continued positive response or stable disease (both radiological and clinically) with no major adverse events, and as long as funding is available for the study. DC vaccines in this phase will be administered every 6 months+/- 2 weeks.~2). Poly-ICLC at 10µg/kg and up to 1640 µg/injection will be administered intramuscularly (i.m.) on the day of each booster DC vaccine. Poly-ICLC will be administered weekly thereafter for twice (at one week and two weeks after each vaccine) (e.g. if the previous DC vaccine was administered on a Thursday, subsequent poly-ICLC will be administered on the next two Thursdays"
