Protox to present prostate cancer data at ASCO conference



    VANCOUVER, Feb. 13 /CNW/ - Protox Therapeutics Inc. (TSX: PRX), a leader
in advancing novel, targeted therapeutic proteins, today announced that data
from the completed Phase 1 clinical study testing PRX302 in patients with
locally recurrent prostate cancer following radiation failure will be
presented at the American Society of Clinical Oncology ("ASCO") Genitourinary
Cancer Symposium in San Francisco, California.
    Scott Coffield, M.D., Principal Investigator from the lead site at Scott
and White Memorial Hospital, will deliver the presentation, entitled
"Intraprostatic Treatment of Patients with Locally Recurrent Prostate Cancer
with the PSA-Activated Protoxin PRX302" on Thursday, February 14, 2008 at the
San Francisco Marriott.
    PRX302 is rationally designed to kill prostate cancer and hyperplastic
cells that over-produce the enzyme prostate specific antigen (PSA). A Phase 1
study has been completed and final results were released in November 2007
indicating that PRX302 is safe and well tolerated while demonstrating
encouraging signs of therapeutic activity. A Phase 2a clinical trial
evaluating PRX302 for the treatment of localized recurrent prostate cancer
following radiation failure has been initiated. The trial is designed to
determine the optimal injection regimen that provides the maximal therapeutic
benefit, while maintaining safety and tolerability of a single intra-prostatic
treatment of PRX302. By increasing the volume and/or number of deposits, it is
anticipated that the treatment effects of PRX302 may extend to larger volumes
of the prostate and, consequently, enhance its therapeutic activity.
