Re-engineered Cold Virus Increases Brain Cancer Patients’ Survival, Phase 1 Trial Shows

Excerpt:

“Re-engineering a common cold virus to attack the deadliest kind of brain tumor extended the survival of patients whose tumor returned after various treatments, including surgery, a Phase 1 clinical trial shows.

“While patients with glioblastoma usually live a median of six months, half were still alive at 9/12 months after receiving the re-engineered virus. And 20 percent lived for three years or longer.”

DNX-2401 Demonstrates “Dramatic” Survival Benefit in Glioma

Excerpt:

“Treatment with the investigational agent DNX-2401 resulted in 20% of a cohort of patients with recurrent malignant glioma surviving more than 3 years from the time of treatment, according to phase I data published in the Journal of Clinical Oncology.

“In the dose-escalation study, patients were enrolled into the treatment-only group A (n = 25) or the treat-resect-treat group B (n = 12). Group A underwent stereotactic biopsy to document recurrence, followed by a single intratumoral injection of DNX-2401 at the assigned dose through the biopsy needle into the contrast-enhancing tumor mass. In group B, stereotactic biopsy and intratumoral injection of DNX-2401 through an implanted catheter was followed 2 weeks later by craniotomy with en bloc tumor resection, and then administration of a second DNX-2401 dose into several locations in the wall of the resection cavity.”

Clinical Trials Test Treatments for High-Grade Brain Tumors


With a few exceptions, glioblastoma (GBM) remains largely incurable, and the U.S. Food and Drug Administration (FDA) has approved few treatments for the disease. Surgery (when feasible), radiation, and temozolomide are used in most patients. But even if a newly diagnosed tumor can be surgically excised, recurrences are too common.

In this blog post, I simply list some of the new treatments available in clinical trials for GBM and other high-grade brain tumors. Only drugs that have at least some preliminary results of activity are included, and the list is not meant to be fully comprehensive. The interested reader can judge for herself what might be of interest, keeping in mind that no single treatment is suitable or will work for all GBM patients. Continue reading…
