Brief Summary:
Phase 1/2 trial to evaluate safety, immunogenicity and preliminary efficacy of INO-5401 and INO-9012 in combination with cemiplimab (REGN2810), with radiation and chemotherapy, in subjects with newly-diagnosed glioblastoma (GBM).

| Glioblastoma | Biological: INO-5401 Biological: INO-9012 Biological: Cemiplimab Radiation: Radiation Therapy Drug: Temozolomide | Phase 1 Phase 2 |
This is a phase 1/2, open-label, multi-center trial to evaluate safety, immunogenicity and preliminary efficacy of INO-5401 and INO-9012 in combination with cemiplimab in subjects with newly-diagnosed glioblastoma (GBM). INO-5401 and INO-9012 will be delivered by intramuscular (IM) injection followed by electroporation (EP) in combination with cemiplimab and chemoradiation and radiation. There will be 2 cohorts in this trial. Cohort A will be participants with a tumor with an unmethylated O6-methylguanine-deoxyribonucleic acid (DNA) methyltransferase (MGMT) promoter. Cohort B will be participants with a tumor with a MGMT methylated promoter or who have indeterminate MGMT status. Both cohorts will receive INO-5401 and INO-9012 and cemiplimab at the same doses and on the same dosing schedule, and both cohorts will receive radiation and temozolomide (TMZ), if clinically indicated.

Experimental: Cohort A: Unmethylated MGMT Promoter
Cohort A will include participants with a glioblastoma tumor with an unmethylated MGMT promoter. Participants will receive INO-5401 and INO-9012 and cemiplimab as well as radiation and temozolomide (TMZ; only during radiation therapy), if clinically indicated.

Biological: INO-5401
INO-5401 is a combination of 3 separate DNA plasmids targeting Wilms tumor gene-1 (WT1) antigen, prostate-specific membrane antigen (PSMA) and human telomerase reverse transcriptase (hTERT) genes. Starting on Day 0 three milligrams (mg) of each plasmid will be delivered IM followed by EP using the CELLECTRA® 2000 EP device every three weeks for four doses, and then every 9 weeks until disease progression as defined by immunotherapy Response Assessment in Neuro-Oncology (iRANO), unacceptable toxicity, withdrawal of consent, or death. Biological: INO-9012 INO-9012 is a DNA plasmid for expression of human interleukin-12 (IL-12). Starting on Day 0 one mg plasmid will be delivered IM followed by EP using the CELLECTRA® 2000 EP device every three weeks for four doses, and then every 9 weeks until disease progression as defined by iRANO, unacceptable toxicity, withdrawal of consent, or death. Biological: Cemiplimab Cemiplimab is an antibody to programmed death-1 (PD-1) protein. Starting on Day 0 cemiplimab will be administered intravenously (IV) every three weeks at a dose of 350 mg per dose in the absence of dose holding, until disease progression as defined by iRANO, unacceptable toxicity, withdrawal of consent, or death.
Other Name: REGN2810 Radiation: Radiation Therapy Radiation therapy (RT) will begin no later than 42 days after surgical intervention, and should start approximately 2 weeks after Day 0. RT will be given for three weeks. Drug: Temozolomide Temozolomide (TMZ) will be given daily during radiation therapy (RT) at a dose of 75 milligrams per square meter (mg/m^2). |
|
Experimental: Cohort B: Methylated MGMT Promoter
Cohort B will include participants with a glioblastoma tumor with a methylated MGMT promoter or with indeterminate MGMT status. Participants will receive INO-5401 and INO-9012 and cemiplimab as well as radiation and temozolomide (TMZ), if clinically indicated. Participants will continue to receive TMZ following radiation therapy, for up to six additional cycles, if clinically indicated.
