DC Vaccination With Td Preconditioning and GM CSF
Human CMV pp65-LAMP mRNA-pulsed autologous DCs containing GM CSF: 2x10\^7 human CMV pp65-LAMP mRNA-pulsed autologous DCs are given intradermally and bilaterally at the groin site (divided equally to both inguinal regions). Patients will receive up to a total of 10 DC vaccines. Temozolomide: Temozolomide is a chemotherapy drug given to all enrolled patients at the post-RT clinic visit as dose-intensified TMZ (100 mg/m2/day for 21 days). Tetanus-Diphtheria Toxoid (Td): Before the first DC vaccination, patients will receive 0.5 mL of Td (tetanus and diphtheria toxoids adsorbed) intramuscularly into the deltoid muscle to ensure adequate immunity to the tetanus antigen. Prior to pp65 DC vaccination #4,(3±1) weeks after leukapheresis 2 the vaccine site will receive a pre-conditioning intradermal injection of Td (1 flocculation unit (Lf), in 0.3 mL of saline for a total of 0.4 mL). GM-CSF: Granulocyte macrophage-colony stimulating factor (GM-CSF) is a sterile, white, preservative-free lyophilized powder in a vial containing 250 mcg that will be reconstituted in 0.5 mL of sterile water for injection and used as an adjuvant with the DC vaccine. 111-Indium-labeling of Cells for in vivo Trafficking Studies: 111-In-labeled DCs are 2 x 10\^7 pp65-LAMP mRNA loaded mature DCs labeled with 111-In (50 μCi / 5 x 10\^7 DCs) and given i.d. as the fourth vaccine. In up to 16 patients, the fourth vaccine will be labeled with 111-In (50 μCi / 5 x 10\^7 DCs) prior to injection.

Timeframe: 5 years

Population: Data not collected.

The Cox proportional hazards model will assess the impact of migration on survival after vaccine #4. Migration is defined as the maximum percentage of 111In-labeled dendritic cells (DCs) reaching inguinal nodes during the 48 hours after the 4th vaccination. The hazard ratio associated with a 1-unit change in migration will be estimated with 95% confidence intervals.CSF to site-draining inguinal lymph nodes after Td pre-conditioning and survival after vaccine # 4.

An unacceptable toxicity is defined as any grade 3 or greater toxicity that is possibly, probably, or definitely attributed to the pre-conditioning agent Td or pp65 DC vaccine that does not resolve to baseline within 3 weeks; any Grade 3 hypersensitivity reactions or autoimmune toxicity requiring steroids or hormone replacement; , and is not due to progressive disease, or any life-threatening event not attributable to concomitant medication, co-morbid event, or disease progression. Toxicities will be graded according to the National Cancer Institute Common Toxicity Criteria of Adverse Events (NCI CTCAE) version 5 criteria.
