- Poster Presented at ASCO Annual Meeting -

SOUTH SAN FRANCISCO, Calif. and CHICAGO, May 31 /PRNewswire-FirstCall/ -- Poniard Pharmaceuticals, Inc. (Nasdaq: PARD), a biopharmaceutical company focused on oncology, today presented preliminary safety and efficacy data from its ongoing Phase 2 clinical trial of picoplatin in combination with docetaxel and prednisone, the standard of care for the first-line treatment of metastatic hormone-refractory prostate cancer (HRPC). Results demonstrated that picoplatin can be safely administered with full doses of docetaxel. In addition, the prostate specific antigen (PSA) response rate was 69 percent in 26 patients evaluable for PSA.

The Company presented the Phase 2 data (abstract #5153) in the General Poster Session during the 44th Annual Meeting of the American Society of Clinical Oncology (ASCO) at McCormick Place in Chicago. Picoplatin, the Company's lead product candidate, is a new generation platinum chemotherapy agent with the potential to become a platform product addressing multiple indications, combinations and formulations.

"The promising results of this Phase 2 trial in HRPC support further development of picoplatin in the treatment of prostate cancer," said Robert De Jager, M.D., chief medical officer of Poniard. "A prospective randomized trial is under consideration. The combination of picoplatin with a taxane could be further evaluated in other tumor types, such as ovarian cancer and non-small cell lung cancer."
