Description

Inclusion Criteria:

1. Newly diagnosed patients with histopathological diagnosis of WHO grade IV glioma (GBM).
2. Age ≥ 18 years.
3. Patient must have undergone a gross/near-gross total surgical resection of tumor by analysis of residual enhancing tumor remnant on the immediate post-operative MRI (within 72 hours after surgery) as defined by ≤ 3 cm2 residual enhancing tumor longest perpendicular planes by MRI.
4. Planned standard adjuvant chemoradiation (SOC RT + TMZ for 6 weeks).
5. Karnofsky performance status ≥ 70.
6. Life expectancy ≥ 3 months.
7. All patients must be able to understand and be willing to sign written informed consent and aware of the investigational nature of the study.
8. Patient has adequate renal function (creatinine ≤ 1.5 times the upper limit of normal [ULN]) or a glomerular filtration rate (GFR) of ≥ 50 mL/min/1.73 m2).
9. Patient has adequate hepatic function, as evidenced by a total bilirubin ≤1.5 times the ULN, aspartate transaminase (AST), and /or alanine transaminase (ALT) ≤3 times the ULN.
10. Patient has adequate bone marrow function, as evidenced by hemoglobin ≥ 9.0 g/dL in the absence of transfusion within the 72 hours prior to the screening visit, platelet count ≥ 100×109cells/L, and absolute neutrophil count (ANC) ≥ 1.5×109 cells/L.

11. Patient and his/her partner agree to use adequate contraception after providing written informed consent through 3 months after the last investigational product dose, as follows:

    • For women: Negative pregnancy test during screening and at baseline and compliant with 2 methods of medically approved contraceptive regimens during and for 3 months after the treatment period or documented to be surgically sterile or postmenopausal.
    • For men: Compliant with 2 methods of medically approved contraceptive regimens during and for 3 months after the treatment period or documented to be surgically sterile.
12. Patient is willing to participate in the study and comply with all study requirements.

Exclusion Criteria:

1. Participation in another therapeutic clinical trial.
2. Implantable electronic device.
3. Pregnant or breast feeding.
4. Tumor location or tumor primarily located in spinal cord or brain stem, multi-focal disease, or significant leptomeningeal disease.
5. Evidence of significantly increased intracranial pressure (midline shift > 5mm, clinically significant papilledema, vomiting and nausea or reduced level of consciousness).
6. Known history of AIDS/HIV. Testing is not required.
7. Patient has a history of other malignancy treated with curative intent within the previous 3 years with the exception of adequately treated non-melanoma skin cancer or carcinoma in situ of the cervix. Patients with previous invasive cancers are eligible if the treatment was completed more than 3 years prior to initiating current study treatment, and there is no evidence of recurrent disease.
8. Patient has an important medical illness or abnormal laboratory finding that, in the Investigator's opinion, would increase the risk of participating in this study.
9. History of unstable cardiac arrhythmia or palpitations [e.g., supraventricular tachycardia, atrial fibrillation, frequent ectopy, or sinus bradycardia (i.e., <50 beats per minute on exam)] prior to study entry. Sinus arrhythmia is not excluded.
10. Any chronic or active neurologic disorder that in the opinion of the Investigator would compromise the patient participation and/or integrity of the study. Patients with seizures due to recent onset of GBM that are medically controlled are eligible.
11. Syncopal episode within 12 months of screening.
12. Presence of any surgical or traumatic metal implants at the site of administration (medial deltoid or vastus lateralis muscles or overlying skin) or conditions incompatible with electroporation per instruction manual of the TriGrid TDS-IM V2.
13. Patients requiring dexamethasone within 7 days before first priming vaccination of ITI-1001.
14. Contraindication to IM injections or blood draws.

15. Less than 2 acceptable potential injection sites for IM injection and electroporation considering the left and right medial deltoid, and anterolateral quadriceps muscles. A site for injection and electroporation is not acceptable if there is inadequate muscle mass to support at least a 19 mm/0.75 inch injection depth or a skinfold thickness measurement of ≥50 mm/1.97 inch as assessed using the provided caliper. Eligible injection sites must also be free from tattoos, hypertrophic skin patches, keloids or other skin conditions which could interfere with the administration procedure or subsequent assessment of local reactogenicity.

    Note: To ensure adequate muscle mass for administrations, for participants with a weight ≤65 kg, potentially eligible administration sites are confined to the outer aspect of the upper thigh (left or right vastus lateralis muscle) (i.e,, the left and right medial deltoid are not eligible administration sites).

16. Any condition that, in the Investigator's opinion, would render the patient unable to comply with the study procedures and requirements.

Exploratory endpoints include evaluation preliminary efficacy; overall survival	Number of participants that alive at pre-defined timepoints; 12 months, 18 months, and 24 months post-baseline visit	Through study completion, up to 2 years post baseline.
Exploratory endpoints include evaluation preliminary efficacy; Progression-Free Survival per iRANO	Number of participants that are confirmed PFM at pre-defined timepoints; 12 months, 18 months, and 24 months post-baseline visit	Through study completion, up to 2 years post baseline.
Exploratory endpoints include changes in immune response	Immunohistochemistry (IHC) evaluation from original biopsy/surgical sample and a second biopsy/surgical procedure if recurrence is suspected. IHC detects cytomegalovirus (CMV) proteins pp65, IE1, and Glycoprotein B (gB) in human glioblastoma multiforme tissues as well as the CMV markers (CD8, CD163, and FOXP3), to observe how various HCMV proteins could contribute to GBM pathogenesis.	Screening and End of treatment, up to 2 years post baseline.
Exploratory endpoints include evaluation preliminary efficacy; Neurological Assessment in Neuro-oncology (NANO) analysis	Changes in Neurological Assessment in Neuro-oncology (NANO) scale from baseline. The NANO scale evaluates 9 major domains of neurologic function that are most relevant to patients with supratentorial, infratentorial, and brainstem tumors, including gait, strength, upper extremity ataxia, sensation, visual fields, facial strength, language, level of consciousness, and behavior. Levels of function for each domain range from 0 to 2 or 0 to 3. A score of 0 indicates normal function, while the highest score indicates the most severe level of deficit for that domain.	Through study completion, up to 2 years post baseline.
Exploratory endpoints include changes in peripheral blood assessment of T cell activation	Parameters include ELISpot, flow cytometry, CMV serology and anti-LAMP1 antibody for evaluation of immune response from the baseline	Through end of treatment, up to 9 months post-baseline
