The relative risk of disease progression favored satraplatin for all pre- specified patient subsets, including prior Taxotere use, geographies, and the presence or absence of pain. For each of the 20 subsets presented today, the reduction in relative risk of disease progression ranged from 26% to 46%, corresponding to hazard ratios between 0.74 and 0.54.

Disease progression in the SPARC trial was defined as the first occurrence of any of several types of progression, including radiologic tumor progression (RECIST for soft tissue lesions or two or more new lesions on a bone scan); skeletal-related events (including a bone fracture, bone surgery or initiation of bisphosphonates); symptomatic progression (pain, weight loss, worsening of performance status); or death from any cause. Approximately 37% of patients in the trial progressed by pain and approximately 36% progressed on radiologic evidence. The hazard ratio for PFS for the subset of patients with pain progression or death was 0.64 (95% CI: 0.51-0.79, p=0.0001), representing a 36% reduction in the relative risk of progression. The hazard ratio for PFS for the subset of patients with radiologic progression or death was 0.64 (95% CI: 0.51-0.81, p=0.0001), representing a 36% reduction in the relative risk of progression. The hazard ratio for PFS for the subset of patients who progressed in ways other than radiologic or pain progression was 0.86 (95% CI: 0.63-1.17, p > 0.05).

In accordance with the recommendation of the independent Data Monitoring Board for the SPARC trial, patients who have not progressed continue to be treated and all patients will be followed for overall survival. As previously communicated, the interim analysis for overall survival conducted in June 2006 showed a trend, although not statistically si
