Gene Therapy + Chemoradiotherapy for Glioblastoma
Trial Summary
What is the purpose of this trial?
Study to assess the safety and efficacy of HSV-tk (gene therapy), valacyclovir, radiotherapy and chemotherapy in recurrent glioblastoma multiforme.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, you must not have had any cytotoxic chemotherapy, radiotherapy, immunotherapy, or investigational drugs for your brain tumor within 3 weeks of starting the study treatment.
What data supports the effectiveness of the treatment ADV/HSV-tk for glioblastoma?
Research shows that using adenovirus vectors to deliver the herpes simplex virus thymidine kinase gene can lead to tumor regression and longer survival in brain cancer models, even when the immune system is active against the virus. This suggests that the treatment could be effective for glioblastoma.12345
Is the gene therapy treatment involving ADV/HSV-tk generally safe for humans?
What makes the Gene Therapy + Chemoradiotherapy treatment for glioblastoma unique?
This treatment combines gene therapy with chemoradiotherapy, using a virus to deliver a gene that makes cancer cells more sensitive to a drug, leading to tumor regression and long-term survival even in the presence of immune responses against the virus. It is unique because it combines cytotoxic (cell-killing) and immune-stimulatory effects, which are not typically present in standard glioblastoma treatments.158910

Eligibility Criteria
This trial is for adults with recurrent anaplastic astrocytoma or glioblastoma multiforme, confirmed by biopsy. Participants must have a life expectancy of at least 12 weeks, be recovered from previous treatments, and not have multifocal disease or brainstem involvement. They should use effective birth control and agree to provide biopsies. Those with other active cancers (except certain skin cancers), pregnant or breastfeeding women, and individuals unable to take oral medications are excluded.Inclusion Criteria

Screening
Participants are screened for eligibility to participate in the trial
Surgery and Initial Treatment
HSV-tk gene therapy is injected during surgery, followed by valacyclovir for 14 days and radiotherapy over 10 sessions within 2 weeks
Chemotherapy
Standard of care chemotherapy is administered concurrent with or after radiotherapy
Follow-up
Participants are monitored for safety and effectiveness after treatment, with MRI or CT every 6-8 weeks for the first year, then every 12-14 weeks
Optional Second Treatment
Patients can receive a second treatment of HSV-tk after 6 months
