TUSTIN, CA--(Marketwire - Feb 13, 2013) - Peregrine Pharmaceuticals (
"We are pleased with the results seen in this very difficult to treat patient population," said Kerstin Menander, MD, PhD, head of medical oncology at Peregrine. "Although the median overall survival improvement is modest, further analysis of the data including subgroups shows some very interesting and potentially promising trends. We look forward to presenting the full data set from this trial later this year at an upcoming scientific meeting."
The pancreatic cancer trial is a randomized, open-label Phase II trial evaluating bavituximab with gemcitabine versus gemcitabine alone in up to 70 patients with previously untreated stage IV pancreatic cancer. The trial allowed the enrollment of patients 18 and older without any age limit, distant organ involvement and ECOG performance status of 0-2. In this trial, bavituximab was generally safe and well tolerated in combination with gemcitabine with similar adverse events occurring in both arms.
"In light of this data, as well as other recent developments in the treatment of pancreatic cancer, we are actively evaluating the next steps for advancing the bavituximab pancreatic program," said Joseph Shan, vice president of clinical and regulatory affairs at Peregrine. "Subgroup analyses from the trial are yielding additional information that we believe will be important in guiding the anticipated future development of bavituximab in this challenging indication. We are considering potential development pathways that would allow us to take advantage of bavituximab's broad potential when combined with other cancer agents. We look forward to providing updates as these plans come together."
Bavituximab is being evaluated by Peregrine and individual clinical investigators in a variety of treatment settings for patients with non-small cell lung cancer in both the front and second-line settings, as well as breast, prostate, liver and rectal cancers in combination with approved chemotherapies and radiation.
Bavituximab is a first-in-class phosphatidylserine (PS)-targeting monoclonal antibody that represents a new approach to treating cancer. Bavituximab is the lead drug candidate from the company's PS technology platform and is currently being tested in seven clinical trials, including two randomized Phase II trials in front-line and second-line non-small cell lung cancer, and five investigator-sponsored trials (ISTs) in additional oncology indications. PS is a highly immunosuppressive molecule usually located inside the membrane of healthy cells, but "flips" and becomes exposed on the outside of cells that line tumor blood vessels, creating a specific target for anti-cancer treatments. PS-targeting antibodies target and bind to PS and block this immunosuppressive signal, thereby enabling the immune system to recognize and fight the tumor.
