VISTA: Valproic Acid, Irinotecan, and Simvastatin for Recurrent Glioma
What this study is about
The goal of this clinical trial is to see if the combination of valproic acid, irinotecan, and simvastatin causes these tumors to stabilize or shrink, which is a sign that these combinations are effective against tumors in patients with recurrent glioblastoma and adults with recurrent IDH-mutated gliomas
View original scientific description
The goal of this clinical trial is to see if the combination of valproic acid, irinotecan, and simvastatin causes these tumors to stabilize or shrink, which is a sign that these combinations are effective against tumors in patients with recurrent glioblastoma and adults with recurrent IDH-mutated gliomas
Interventions
DRUG
Valproic Acid (VPA)
Day 1 40mg/kg/dose PO BID and simvastatin at 40mg PO daily
DRUG
Irinotecan
D2 irinotecan 180mg/m2 IV and VPA 40mg/kg/dose PO BID, simvastatin at 40mg PO daily
DRUG
Simvastatin
Day3-21 Continuous simvastatin starting at 40mg daily PO
Primary outcome measures
Assessing Efficacy as Measured By Response Rate Of Valproic acid, Irinotecan, and Simvastatin in Recurrent Glioma
Time frame: through study completion, an average of 6 months from start of treatment
The response is defined as a confirmed complete response (CR) or partial response (PR) defined by RANO 2.0. Response rate will be calculated as the number of observed response (PR or CR) divided by all treated subjects in the arm.

Frequently asked questions
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.
