Participant Flow

Dates of recruitment period: 1/2012 - 8/2015 Types of location: Medical clinic

Study enrollment patients must satisfy inclusion criteria, screening evaluations (vital signs, history, physical, neurological exams, Karnofsky Performance Scale, brain MRI , urinalysis, complete blood count, differential, platelets, coagulation tests), underwent leukapheresis, and had suitable Dendritic Cell (DC) Vaccine manufactured for them.

PRIMARY outcome

Timeframe: Each case was assessed from the baseline date of surgery to MRI evidence of tumor progression through study completion, up to 44 months.

Population: Completed the maximum time allowed on study without being affected by Tumor Recurrence or Progression.

a Kaplan-Meier curve of the PFS of our trial patients was created and compared to the PFS of control patients matched for tumor grade, recurrence number, IDH1 status and 1p/19q status.

SECONDARY outcome

Timeframe: The timeframe for OS was from the date of surgery until the date of death from any cause, up to 44 months.

From date of enrollment until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 100 months. a Kaplan-Meier curve of the OS of our trial patients was created and compared to the OS of control patients matched for tumor grade, recurrence number, IDH1 status and 1p/19q status.

SECONDARY outcome

Timeframe: Tumor for analysis (CD8, Programmed Death (PD)-1, PD-L1, mutation analysis) was collected at the vaccine-related surgery shortly after enrollment. Blood for analysis (IDH1-specific antibodies) was collected at Day 0, before the first vaccine injection.

Population: Quantitative multiplex immuno-histochemical (IHC) of pre-treatment glioma microenvironment of IDH1-specific antibodies

Tumor and peripheral blood samples were collected from each of the participants and analyzed for the following biomarkers: IDH1-specific antibodies CD8, PD-1, and PD-L1 content, and correlations among those three biomarkers Mutation analysis/sequencing
