Brief Summary:
Potential subjects with progressive Grade II primary brain tumor that have IDH1 positive testing from the primary tumor (initial diagnosis) will be offered this treatment study in order to test the safety of the PEPIDH1M vaccine in combination with standard chemotherapy (temozolomide).

Condition or disease Intervention/treatment Phase
Brain Cancer Brain Neoplasm, Primary Brain Neoplasms, Recurrent Brain Tumor Cancer of the Brain Biological: PEPIDH1M vaccine Biological: Tetanus-Diphtheria Toxoid (Td) Drug: Temozolomide Phase 1

Detailed Description:

After informed consent has been signed, subjects will undergo standard of care vaccination with 0.5 mL of Td (tetanus and diphtheria toxoids adsorbed) intramuscularly into the deltoid muscle to ensure adequate immunity to the tetanus antigen.

Eligible subjects will undergo a 1-2 hour leukapheresis (to pull off white blood cells) for immune monitoring. Within 48 hours of leukapheresis, subjects will receive vaccine site pre-conditioning as a single dose of Td toxoid (in a total volume of 0.4 mLs salt water/saline) given in the intradermal space (just under the surface of the skin) to the right groin area. The pre-conditioning will be administered one day prior to receiving PEPIDH1M vaccine. The peptide vaccine is administered in the upper thigh area approximately 4 inches below the groin in the intradermal space as vaccine # 1. Subsequent vaccines will be given on day 15 ±3 days (vaccine #2) and day 29 ±3 days (vaccine #3). Each injection of the peptide vaccine will be given half on the right groin and half on the left groin. The first 3 peptide vaccine injections will occur without temozolomide (standard of care chemotherapy).

Seven to twelve days after the 3rd vaccine, subjects will have standard of care surgery to remove the tumor. Tumor samples will be evaluated for the IDH1 markers and analyzed for other cells that may have entered the tumor.

Based on the the tissue obtained at surgery, subjects with stable histologic grade at recurrence will then be treated with vaccine and temozolomide. During monthly cycles of temozolomide, subjects will receive the vaccine on day 22 (+ 2 days) for a maximum of 15 total vaccines (which includes the first 3 bi-weekly vaccines). Patients that have transitioned to a higher grade brain tumor at the time of surgery will receive temozolomide and radiation therapy per standard of care and monthly vaccines (vaccines #4-6). After completion of radiation therapy, subjects in this treatment group will receive vaccines monthly on day 22 (+2 days) with post-RT cycles of TMZ to a maximum of 15 vaccines.

All Adverse Events will be collected from time of consent until off study. The treatment phase of the study will end 1 month after the last vaccine. Patients will be followed only for overall survival, progression-free survival, and subsequent therapies thereafter.

Subjects will have blood collected for immune monitoring and biomarker testing during the following times: prior to initiating vaccine therapy (at the leukapheresis visit), prior to surgery to remove the tumor, at the clinic visit prior to starting first cycle of temozolomide after surgery (or radiation therapy and temozolomide for those who transition to higher grade), at vaccine #6, and at end of vaccine treatment (1 month after vaccine #15 or time the subject comes off study, whichever comes first).

Subjects will be imaged with contrast-enhanced magnetic resonance imaging (MRI) according to standard of care every 10 weeks (+/- 4 weeks) while on temozolomide and afterward, per the treating neuro-oncologist's recommendation. Revised Assessment in Neuro-Oncology (RANO) criteria will be used for assessment of pseudoprogression and tumor progression. Subjects demonstrating definitive progression will be removed from study.

As part of standard care for these subjects, upon tumor progression, participants may undergo biopsy or resection. As this is not a research procedure, consent will be obtained separately. Subjects that have this procedure done within the Duke University Health System will be asked to have a portion of the tumor sample, if possible, to assess immunologic cell infiltration, antigen expression, and biomarkers for immunologic response.

Arm Intervention/treatment
Experimental: PEPIDH1M vaccine
PEPIDH1M vaccine is made up of a peptide that spans the mutated region of IDH1R132H (Isocitrate Dehydrogenase 1). The peptide is administered with GM-CSF (Granulocyte Macrophage Colony Stimulating Factor) mixed with Montanide ISA 51.
Biological: PEPIDH1M vaccine
PEPIDH1M vaccine is made up of 500 µg of 25 amino acid peptide administered with 150 µg of GM-CSF mixed 1:1 with Montanide ISA 51 administered intradermally. The peptide vaccine is administered in the groin area approximately 10 cm below the inguinal ligament.

Biological: Tetanus-Diphtheria Toxoid (Td)
After consent has been signed, all subjects will undergo standard of care vaccination with 0.5 mL of Td (tetanus and diphtheria toxoids adsorbed) intramuscularly (I.M.) into the deltoid muscle to ensure adequate immunity to the tetanus antigen. Within 48 hours of leukapheresis, subjects will receive a vaccine site pre-conditioning as a single dose of Td toxoid (1 flocculation unit, Lf, in a total volume of 0.4 mLs saline) administered intradermally to the right side of the groin one day prior to receiving the first PEPIDH1M vaccine.
Other Name: Tenivac

Drug: Temozolomide
Subjects are treated with temozolomide (TMZ) at a targeted dose of 50-100mg/m2/d for 21 days every 28 days for up to 12 cycles. Subjects that have transitioned to a higher grade brain tumor at time of surgery will receive TMZ and radiation therapy per standard of care before starting TMZ cycles.
Other Name: Temodar

Primary Outcome Measures :
  1. The percentage of patients with an unacceptable toxicity will be estimated. [ Time Frame: Adverse events will be recorded from the time the subject signs the 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.

Secondary Outcome Measures :
  1. IFNγ ELIspot Measurements [ Time Frame: Levels of immune response will be examined after 3 vaccinations (i.e., pre-surgery) as well as after 3 additional post-surgery vaccinations, an expected average of 24 weeks after study initiation. ]
    The mean difference in the number of spot-forming cells (SFC) per 10^6 lymphocytes cultured with and without IDH1 peptide will be calculated. A response will be considered positive if this value is greater than 20 SFC per 10^6 lymphocytes after determining the level of detection in the IDH ELISpot.
