Registered outcomes2

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPercentage of Participants With an Unacceptable ToxicityDate of consent through 2 months after the last vaccination
The percentage of patients who experience an unacceptable toxicity defined as any Grade 3 toxicity at least possibly attributed to the vaccine (or vaccine + TMZ and/or RT) that does not resolve to baseline within 3 weeks, any Grade 3 hypersensitivity reactions requiring steroids, any Grade 4 toxicity, including neurologic events not due to progressive disease, or any life threatening-event not attributable to concomitant medication, co-morbid event, or disease progression.
SecondaryPercentage of Patients With a Positive Vaccine Response After 3 Post-Surgery Vaccines as Measured by IFNγ ELIspotFrom time of pheresis #1, one day prior to first pre-surgery vaccine dose, until the time of the third post-surgery vaccination, an expected average of 24 weeks after study initiation
Assess the immunogenicity of the PEPIDH1M vaccine with adjuvant TMZ using ELISpot. This will be done by finding the difference between the number of SFC after 3 post-surgery vaccines and the number of SFC at baseline for each evaluable subject. Immunogenicity will then be summarized by the percentage of evaluable subjects who have a positive vaccine response after 3 post-surgery vaccines. A response will be considered positive if the difference in SFC measurement is greater than 20 SFC per 10\^6 lymphocytes after determining the level of detection in the IDH ELISpot.
