Arm | Intervention/treatment |
---|---|
Experimental: IGV-001
Participants will be implanted with biodiffusion chambers containing IGV-001 on Day 1 and explanted on Day 3 (at approximately 48 hours following implantation). After 6 weeks, participants will receive radiotherapy (RT) per institutional standards for 5 days per week along with temozolomide 75 mg/m^2 orally, once daily (QD) for up to 12 weeks followed by temozolomide 150 to 200 mg/m^2, orally, on Days 1 to 5 of each 28-day cycle for up to 6 cycles (Week 41).

Combination Product: IGV-001 Cell Immunotherapy
IGV-001, an immunotherapeutic product that combines personalized whole tumor-derived cells with an antisense oligonucleotide (IMV-001) in implantable biodiffusion chambers. Procedure: Standard of Care (SOC): Radiation Therapy Radiation therapy administered per institutional standards. Drug: SOC: Temozolomide Temozolomide administered orally. |
Placebo Comparator: Placebo
Participants will be implanted with biodiffusion chambers containing placebo on Day 1 and explanted on Day 3 (at approximately 48 hours following implantation). After 6 weeks, participants will receive RT per institutional standards for 5 days per week along with temozolomide 75 mg/m^2 orally, QD for up to 12 weeks followed by temozolomide 150 to 200 mg/m^2, orally, on Days 1 to 5 of each 28-day cycle for up to 6 cycles (Week 41).

Combination Product: Placebo
Placebo in implantable biodiffusion chambers containing a predetermined inactive solution. Procedure: Standard of Care (SOC): Radiation Therapy Radiation therapy administered per institutional standards. Drug: SOC: Temozolomide Temozolomide administered orally. |
- Progression-free Survival (PFS) [ Time Frame: Up to 36 months ]PFS is defined as the time from randomization to first progression, as determined by the central radiology review group blinded to the study treatment arm, or death.
- Overall Survival (OS) [ Time Frame: Up to 48 months ]OS is defined as the time from randomization to death due to any cause.
- Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Up to 36 months ]An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. AEs will be graded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0 from mild (Grade 1) to death (Grade 5). SAE is an AE or adverse reaction which is considered serious if it results in any of the following outcomes: death, life-threatening AE, require hospitalizations or prolongation of hospitalizations, results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect and is a medically important event.
- Number of Participants With Clinically Significant Laboratory Assessment Abnormalities [ Time Frame: Up to 36 months ]
- Number of Participants With Clinically Significant Vital Signs Measurements [ Time Frame: Up to 36 months ]
- Number of Participants With Clinically Significant Physical Examination Findings [ Time Frame: Up to 36 months ]
- Time to Deterioration of Karnofsky Performance Status (KPS) Score [ Time Frame: Up to 36 months ]Time to KPS deterioration is defined as the time from screening to the first date of deterioration of the KPS score. Deterioration of KPS is defined as a stable or increasing steroid dose-dependent stabilization of a KPS score of <70 over 2 consecutive visits at least 4 weeks apart. KPS is an 11-level score which ranges between 0 (death) to 100 (complete healthy status); a higher score represents a higher ability to perform daily tasks.
- PFS in Participants With O6-methylguanine-DNA Methyltransferase (MGMT) With Methylation [MGMT+] and MGMT Without Methylation [MGMT-] [ Time Frame: Up to 36 months ]PFS is defined as the time from randomization to first progression, as determined by the central radiology review group blinded to the study treatment arm, or death. MGMT status will be determined per epigenetic and tumor proliferation analysis from tissue obtained during surgery.
- OS in Participants With MGMT+ and MGMT- [ Time Frame: Up to 48 months ]OS is defined as the time from randomization to death due to any cause. MGMT status will be determined per epigenetic and tumor proliferation analysis from tissue obtained during surgery.

Ages Eligible for Study: | 18 Years to 70 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Key Inclusion Criteria:
- Has a Karnofsky performance scale (KPS) score ≥ 70 at screening
- Has a diagnosis of GBM (WHO GRADE III or Grade IV GBM) based on the treating neurosurgeon's best clinical judgement
- Has a diagnostic contrast-enhanced magnetic resonance imaging (MRI) scan with fluid attenuated inversion-recovery (FLAIR) sequence of the brain at screening. Participants must have a confirmed measurable disease pre-operatively with at least 1 lesion measuring a total bi-perpendicular product of 4 centimeter square (cm^2) in 2 different planes (axial, sagittal, or coronal)
- The tumor must be located in the supratentorial compartment
- Has adequate bone marrow and organ function at screening
Key Exclusion Criteria:
- Has bi-hemispheric disease, multicentric disease, or disease burden involving the brain stem or cerebellum based on MRI post-gadolinium enhancement
- Has received any previous surgical resection or any anticancer intervention for GBM
- Has recurrent glioma, a concurrent malignancy, or malignancy within 3 years of randomization, unless definitive therapy is completed, with the exception of basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the cervix or breast that has completed curative therapy
- Has any severe immunocompromised condition (eg, human immunodeficiency virus (HIV) with a cluster of differentiation [CD] 4+ cell count <200*10^6/liter [L]) or any active uncontrolled autoimmune disease (eg, Crohn's disease)
- Has an active cardiac disease or a history of cardiac dysfunction
- Is receiving any other investigational agent(s) or has received an investigational agent within 30 days or 5 half-lives of investigational agent use, whichever is longer, prior to screening
- Is partaking in another interventional study. Participants who are partaking in an observational study are eligible
- Has received a live vaccine within 30 days of screening
- Has active and uncontrolled/untreated hepatitis B virus (HBV), hepatitis C virus (HCV), HIV, or any other active infections that, in the Investigator's opinion, would impair or prohibit a participant's participation in this study.
- Is receiving treatment with Tumor Treating Fields or Optune®
