BERLIN, March 22, 2007 /PRNewswire-FirstCall/ -- Pharmion Corporation and GPC Biotech AG today announced additional data from the double-blind, randomized satraplatin Phase 3 registrational trial, the SPARC trial (Satraplatin and Prednisone Against Refractory Cancer) which were presented today at the 22nd Annual European Association of Urology Congress in Berlin, Germany. The trial is evaluating satraplatin plus prednisone versus placebo plus prednisone in 950 patients with hormone-refractory prostate cancer (HRPC) who have failed prior chemotherapy.
"Second-line chemotherapy for patients with hormone-refractory prostate cancer represents a true unmet medical need and the encouraging satraplatin data suggest that for the first time, we may have a treatment option for these patients with advanced disease," said Professor Fred Witjes, Professor of Urology, Academisch Ziekenhuis, Nijmegen, The Netherlands. "In particular, the very impressive pain and PSA response rates seen in the SPARC study, especially considering the fact that all these patients were progressive after hormones and chemotherapy, further suggest satraplatin's active anti-tumor effect in this patient population."
Data presented today from the SPARC study showed that pain response rates for patients treated with satraplatin were statistically significantly superior compared to the pain response rates for those patients in the comparator arm. Pain response rates were 24.2 percent for the satraplatin plus prednisone arm compared with 13.8 percent for the placebo arm (p=0.005).
Pain response was assessed by patients using a weekly present
pain intensity (PPI) and analgesic score. The PPI score was defined
according to the McGill-Melzack questionnaire with 0 = no pain, 1 =
mild pain, 2 = discomforting pain, 3
