Gliadel(R) Wafer Clinical Data Presented at Society for Neuro-Oncology Meeting
ORLANDO, Fla., Nov. 20 /PRNewswire-FirstCall/ -- MGI PHARMA, INC.
(Nasdaq: MOGN), a biopharmaceutical company focused in oncology and acute
care, today summarized interim results from a phase 2 combination study of
Gliadel(R) Wafer (polifeprosan 20 with carmustine implant) in patients with
newly-diagnosed, resectable, high grade malignant gliomas presented at the
2006 Society for Neuro-Oncology (SNO) Annual Meeting. Interim data from 35
patients with this aggressive brain tumor showed a median survival of 18.6
months when Gliadel Wafer and temozolomide are used in combination with
surgery and radiotherapy.
"Although preliminary, these data are intriguing and warrant additional
clinical investigation," commented Renato LaRocca, M.D., Principal
Investigator of the study and Director of the Kentuckiana Cancer Institute.
"By using quadruple-modality therapy, we may be having an impact on select
patients with this devastating tumor. With each new study in brain tumors,
we gain further insight into the appropriate sequencing of novel treatment
combinations."
About the Study
This phase 2, multi-center trial began in July 2003 and is planned to
enroll a total of 40 patients. Eligible patients were 18-72 years of age
with surgically operable, initial high-grade malignant glioma. Patients
underwent craniotomy and Gliadel Wafer implantation (7.7 mg carmustine per
wafer), followed by limited field radiotherapy (2 Gy/day x 30 fractions)
with concomitant temozolomide (75 mg/m(2)/day), and then up to 18
sequential cycles of monthly temozolomide (200 mg/m(2)/day for 5 days) as
tolerated unless there was evidence of disease progression. Pneumocystis
carinii prophylaxis was not required during concomitant treatment with
radiotherapy and temozolomide.
As of September 29, 2006, 35 patients have been enrolled at three
centers. Glioblastoma multiforme was diagnosed in 34 patients and
anaplastic astrocytoma in one patient. The median patient age is 57 years,
and the median Karnofsky Performance Status is 100 (range 70-100). At
interim analysis, median follow-up was 10.4 months (range 0.6-29.7).
Recurrence has been documented in 25 patients and 19 patients have died.
Three patients were withdrawn from the study, one patient withdrew and
transferred care following recurrence, and one patient died prior to
initiation of radiotherapy and concomitant temozolomide. Median survival is
18.6 months and the 1-year survival rate is 64%. Median progression free
survival is 6.4 months and the one year progression free survival is 30%.
The most frequently reported adverse event included constipation (14
patients), nausea (14 patients) and fatigue (11 patients). Trial sites
include Kentuckiana Cancer Institute, the University of Missouri School of
Medicine and Baylor College of Medicine.
About Gliadel(R) Wafer
Gliadel Wafer (polifeprosan 20 with carmustine implant) is a
biodegradable wafer containing the chemotherapy agent carmustine, or BCNU,
and is indicated in newly diagnosed patients with high-grade malignant
glioma as an adjunct to surgery and radiation. Gliadel Wafer is also
indicated in recurrent glioblastoma multiforme patients as an adjunct to
surgery. Gliadel Wafer is the only FDA approved brain cancer treatment
capable of providing localized delivery of chemotherapy directly to the
site of the tumor. Up to eight Gliadel wafers can be implanted in the
resection cavity after a tumor is surgically removed. As a Gliadel Wafer
dissolves, BCNU is delivered locally, providing chemotherapy to the
surgical resection cavity.
Side effects have been reported in patients receiving Gliadel Wafer.
Although these events may result as a consequence of brain surgery
(craniotomy) without Gliadel Wafer, they may occur more frequently when
Gliadel Wafer is used. The following categories of adverse events are
possibly related to treatment with Gliadel during initial resection
including seizure, brain edema, healing abnormalities, and intracranial
infection. The following four categories of adverse events are possibly
related to treatment with Gliadel for recurrent disease: post-operative
seizure, healing abnormalities, intracranial hypertension and intracranial
infection.
