MGI PHARMA Announces Results from Study Involving the Dual Implantation of Gliadel(R) Wafer and Radioactive Seeds for Treatment of Recurrent Glioblastoma MultiformeNew Data Published in Journal of Neurosurgery Suggest a Novel Treatment Combination of Localized Therapies Shows Promise
MINNEAPOLIS--(HSMN NewsFeed)--MGI PHARMA, INC. (NASDAQ:MOGN ), a biopharmaceutical company focused in oncology and acute care, today announced that study results published in the February issue of the Journal of Neurosurgery show that treatment of patients who have recurrent glioblastoma multiforme (GBM) with both Gliadel® Wafer and radioactive seeds (iodine-125) at the time of tumor resection, may provide for a better outcome than treatment of patients with surgery and either agent alone.
The study was led by Ronald E. Warnick, M.D., Chairman of the Mayfield Clinic and professor of neurosurgery at the University of Cincinnati. This is the first study ever conducted to evaluate the effect of these two novel agents used simultaneously in combination with surgery to treat recurrent GBM. The Phase 1/2 single-arm study explored the safety and efficacy of the localized therapies in 34 patients. The dual implantation of Gliadel Wafer and radioactive seeds was well-tolerated among patients and may contribute to longer survival than when surgery is coupled with either therapy alone. Additional controlled clinical trials will need to be conducted in order to confirm this finding and demonstrate a survival benefit in comparison to control.
“Recurrent glioblastoma is a challenging disease, because the tumor grows and spreads so quickly,” Dr. Warnick said. “These results suggest that by simultaneous application of two localized therapies, Gliadel Wafer and radioactive seeds, we may be able to provide an improved survival benefit for this patient population. We will continue to conduct further studies of this approach for both recurrent and newly diagnosed glioblastoma.”
About Gliadel® Wafer
Gliadel® (polifeprosan 20 with carmustine implant) Wafer is indicated in patients with newly diagnosed high-grade malignant glioma as an adjunct to surgery and radiation. Gliadel is also indicated in patients with recurrent glioblastoma multiforme as an adjunct to surgery. Gliadel should not be given to individuals who have demonstrated a previous hypersensitivity to carmustine or any of the components of Gliadel. Patients undergoing craniotomy for malignant glioma and implantation of Gliadel should be monitored closely for complications of craniotomy, including seizures, intracranial infections, abnormal wound healing, and brain edema.
Communication between the surgical resection cavity and the ventricular system should be avoided to prevent the wafers from migrating into the ventricular system and causing obstructive hydrocephalus. If a communication larger than the diameter of a wafer exists, it should be closed prior to wafer implantation. Computed tomography and Magnetic Resonance Imaging of the head may demonstrate enhancement in the brain tissue surrounding the resection cavity after implantation of Gliadel. This enhancement may represent edema and inflammation caused by Gliadel or tumor progression. The short-term and long-term toxicity profiles of Gliadel, when given in conjunction with chemotherapy have not been fully explored.
