Northwest Biotherapeutics, Inc. ("NWBT" or the "Company") (OTC Bulletin Board: NWBO) today announced further positive long-term follow-up data from its prior Phase I and Phase I/II clinical trials, in which patients with newly diagnosed Glioblastoma multiforme ("GBM"), the most rapid and lethal type of brain cancer, were treated with NWBT's DCVax®-Brain personalized immune therapy.
The data through July 1, 2010, show that no patients died during the 9-month period since the last data update (through September 2009). The data also show that median survival was 3 years, 33% of the patients reached 4-year survival, and 27% reached or exceeded 6-year survival (up from 22% who had reached or exceeded 6-year survival as of the last data update). The longest surviving patient to date has now exceeded 10 years.
GBM is a highly lethal cancer: with standard of care treatment (including surgery, radiation and chemotherapy), patients with newly diagnosed GBM have a median survival of only about 14.6 months, and less than 5% of such patients are still alive at 5 years.
"We're excited and encouraged by the continued extension of survival in the patients who received DCVax® in the prior clinical trials," commented Dr. Al Boynton, NWBT's CEO, "especially since DCVax® is non-toxic, unlike chemotherapies, and involves just a simple injection under the skin, like a flu shot."
