A Trial to Evaluate Multiple Regimens in Newly Diagnosed and Recurrent Glioblastoma

DRUG

Temozolomide

Dosage Form: Capsule for oral administration Strengths: 5 mg, 20 mg, 100 mg, 140 mg, 180 mg, or 250 mg

DRUG

Lomustine

Dosage Form: Capsule for oral administration Strength: 5 mg, 10 mg, 40 mg, and 100 mg

DRUG

Regorafenib

Dosage Form: Tablet for oral administration Strength: 40 mg Standard Regimen: 160 mg orally (PO) every day (QD) for 3 weeks of every 4 week cycle (i.e., 3 weeks on, 1 week off)

RADIATION

Radiation

60 Gy

DRUG

Paxalisib

Dosage Form: Tablet for oral administration Strength: 15 mg Standard Regimen: 45 mg orally (PO) every day for 28 days for the first cycle. If tolerated, increase dose to 60 mg orally (PO) every day for 28 days for all subsequent cycles

DRUG

VAL-083

Dosage Form: Infusion for intravenous administration Strength: 40 mg per vial Standard Regimen: 30 mg/m2 on Day 1, 2 and 3 of 21-day cycle. The drug is available in powder form. It is reconstituted with 5 mL of 0.9% Sodium Chloride for Injection, USP. This will produce a solution of 40 mg VAL-083 in 5 mL. The required volume of reconstituted VAL-083 for the patient is then calculated at the rate of 30 mg/m2. The corresponding volume is further diluted into 250 mL of 0.9% Sodium Chloride for Injection, USP, prior to intravenous administration.

DRUG

VT1021

Dosage Form: Infusion for intravenous administration Strength: 10 mg/mL Standard Regimen Newly Diagnosed: Dose as confirmed through the dose finding phase, administered twice weekly (Mon and Thurs or Tues and Fri or Mon and Fri). Standard Regimen Recurrent: 12 mg/kg administered twice weekly (Mon and Thurs or Tues and Fri or Mon and Fri). The drug is available as a sterile solution of the acetate salt formulated with phosphate-buffered saline, mannitol, and 2.5% polysorbate 80. The required volume stock solution for the patient is calculated. The corresponding volume is diluted in 500 mL of either 0.9% saline or D5W, prior to intravenous administration.

DRUG

Troriluzole

Dosage Form: Capsule for oral administration Strength: 100 mg Standard Regimen: Dose as confirmed through the dose finding phase orally BID.

BIOLOGICAL

ADI-PEG 20

Dosage Form: Solution for intramuscular injection Strength: 11.5 ± 1.0 mg/ml Standard Regimen: For newly diagnosed patients, 36mg/m2. For recurrent disease patients, dose as confirmed through the dose finding phase intramuscularly once a week

DRUG

AZD1390

Standard Regimen Newly Diagnosed: Given once daily on days of radiation and once daily for 14 consecutive days after completion of radiation.

DRUG

Tinostamustine

Dosage form: Reconstituted powder for intravenous administration Strength: 2mg/mL Standard Regimen: Dose as confirmed through the dose finding phase, on Day 1 of 21-day cycle for up to 12 cycles in the maintenance phase.

Overall Survival (OS)

Time frame: From date of randomization until the date of death from any cause, or until 12 months following last patient randomization (approximately 2 years), whichever comes first.

Overall survival is defined from the time of randomization to death from any cause. Patients still alive at the time of an analysis will be considered censored at their date of last contact.

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
