Clinical trial for Malignant Glioma of Brain
Official title Adenovirus Mediated Suicide Gene Therapy With Radiotherapy in Progressive Astrocytoma.
ClinicalTrials.gov ID: NCT05686798
What this study is testing
What is Ad5-yCD/mutTKSR39rep-ADP adenovirus and fractionated stereotactic radiosurgery (fSRS)?
An investigational oncolytic virus therapy being studied for malignant glioma of the brain. It is designed to deliver suicide genes (yCD and mutant TK) to tumor cells so that oral prodrugs (5‑FC and valganciclovir) are converted into toxic compounds that kill the cancer cells.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether a virus that carries two suicide genes can be given safely with radiation.
- Who it's for
- You may be able to join if you have a recurrent high‑grade astrocytoma and are having tumor surgery.
- What's involved
- You would receive an injection of a modified virus into the tumor area during surgery, then have a series of precise radiation treatments.
- Time commitment
- The study lasts a few weeks and includes the surgery, radiation sessions, and follow‑up visits.
- Phase 1: an early, usually small safety study
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
Who can take part
Ages 18 and older
You may be able to join if
- Histologically documented glioblastomas or anaplastic astrocytoma prior to the debulking surgery that is suspicious to have progressed on imaging.
- Patients must be ≥ 18 years of age, able to provide informed consent and express a willingness to meet all the expected requirements of the protocol...
- Must have recovered from toxicity (grade 2 or less) of prior therapy.
- Eligible for partial or total resection of the recurrent tumor
- No anticipated physical connection between post-resection tumor cavity and cerebral ventricle
You likely can't join if
- Acute infection. Acute infection is defined by any viral, bacterial, or fungal infection that has required active treatment and caused oral...
- Serum antibodies to human immunodeficiency virus (HIV)
- Previous history of liver disease including autoimmune or viral hepatitis
- Positive serologic test for Hepatitis B or C at baseline
- Immunosuppressive therapy except for corticosteroid use
- Serious medical or psychiatric illness or concomitant medication, which, in the judgment of the investigator, might interfere with the subject's...
