Study Details

Study Description

Brief Summary

This Phase I clinical trial will evaluate the safety, tolerability, immunogenicity, and preliminary efficacy of 8 mg ITI-1001 in participants with newly diagnosed glioblastoma (GBM).

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

This Phase I study will evaluate the safety and immunogenicity of 8 mg ITI-1001 DNA vaccine based on safety, immune activation and preliminary assessment of therapeutic benefit of 2 priming vaccinations given in the 4-6 weeks period between definitive surgical resection and initiation of SOC chemoradiation followed by 2 post-chemoradiation priming vaccinations (#3 and #4) and 5 ITI-1001 vaccine boosters given in parallel with maintenance TMZ as per Schedule of Assessments.

The study duration will be approximately 24 months for individual patients, excluding screening and surgery.

ITI-1001 vaccinations will be given in combination with Td toxoid.

8mg of ITI-1001 DNA vaccine will be administered via IM injection with electroporation up to 9 times using the TDS-IM v2.0 Device according to the device manufacturer's instructions and according to the Schedule of Assessments.

Standard of Care MRI and 4 times of PET imaging with 18F-AraG are scheduled. 18F-AraG has been approved by the US FDA for T cell acute lymphoblastic leukemia and T cell lymphoblastic lymphoma.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Participants with Newly Diagnosed Glioblastoma (GBM)

Ten participants with histopathological diagnosis of WHO grade IV glioma (Glioblastoma; GBM) and have undergone a gross/near gross total surgical resection of tumor by analysis of residual enhancing tumor remnant on the immediate post-operative MRI

Drug: ITI-1001
ITI-1001 DNA vaccine represents a multi-antigen nucleic acid cancer immunotherapy encoding 3 CMV antigens. The vaccine is comprised of 2 DNA plasmids: 1 plasmid encoding IE-1 and pp65 antigens as a fusion protein with LAMP1. Another plasmid encodes gB antigen as a fusion protein with LAMP1.

Outcome Measures

Primary Outcome Measures

  1. Number of participants with Dose Limiting Toxicities (DLTs). [Through study completion, up to 2 years post baseline.]

    Number of participants that experience any Dose Limiting Toxicities (DLTs).

  2. Number of occurrences of Adverse events/Serious Adverse Events that will be assessed for severity according to the NCI CTCAE, version 5.0. [Through study completion, up to 2 years post baseline.]

    Number of occurrences of Adverse events/Serious Adverse Events that will be assessed for severity according to the NCI CTCAE, version 5.0.

Other Outcome Measures

  1. Exploratory endpoints include changes in peripheral blood assessment of T cell activation [Through study completion, up to 2 years post baseline.]

    Parameters include ELISpot, flow cytometry, CMV serology and anti-LAMP1 antibody for evaluation of immune response from the baseline

  2. Exploratory endpoints include changes in immune response [4 times of 18F-AraG PET imaging through study completion, up to 2 years post baseline.]

    Utilizing 18F-AraG, which accumulates in activated T-cells, PET imaging four times during the course, and monitoring the immune response is performed to assess tumor bed infiltration by activated T-cells following vaccination.

  3. Exploratory endpoints include changes in immune response [Through study completion, up to 2 years post baseline.]

    Immune assessments for analytical evaluation of MRI data for possible tumor relapse or activated immune cells (inflammation associated with "pseudo-progression")

  4. Exploratory endpoints include evaluation preliminary efficacy; overall survival [Through study completion, up to 2 years post baseline.]

    Number of participants that alive at pre-defined timepoints; 12 months, 18 months, and 24 months post-baseline visit

  5. Exploratory endpoints include evaluation preliminary efficacy; Progression-Free Survival per iRANO [Through study completion, up to 2 years post baseline.]

    Number of participants that are confirmed PFM at pre-defined timepoints; 12 months, 18 months, and 24 months post-baseline visit

  6. Exploratory endpoints include changes in immune response [Screening and End of treatment, up to 2 years post baseline.]

    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.

  7. Exploratory endpoints include evaluation preliminary efficacy; Neurological Assessment in Neuro-oncology (NANO) analysis [Through study completion, up to 2 years post baseline.]

    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.

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).
