Arms Assigned Interventions
Experimental: 1
Prednisone and Satraplatin (INN / USAN), also known as JM-216, or OC-6-43-bis(acetato-O)ammine dichloro (cyclohexanamine)-platinum (IV), is a member of a novel class of platinum (IV) compounds that are absorbed by the oral route. The lipophilic properties of these compounds, and hence their absorption, are largely determined by the nature of the axial acetate ligands.
Drug: Oral Satraplatin
The SPERA protocol states that satraplatin may be continued until evidence of disease progression (at the discretion of the investigator), intolerable toxicity, withdrawal of informed consent, or non compliance. The treatment consists of satraplatin 80 mg/m2 administered by mouth once daily for five consecutive days (days 1-5) plus prednison 5 mg po twice daily. The treatment cycle is repeated every 35 days.
Experimental: 2
Prednisone (17 alpha, 21-dihydroxypregna-1, 4-diene-3, 11, 20-trione) is commercially formulated as the acetate salt (prednisone 21-acetate). It is a biologically inert glucocorticoid, which is converted to active prednisolone in the liver.
Drug: Oral Satraplatin
The SPERA protocol states that satraplatin may be continued until evidence of disease progression (at the discretion of the investigator), intolerable toxicity, withdrawal of informed consent, or non compliance. The treatment consists of satraplatin 80 mg/m2 administered by mouth once daily for five consecutive days (days 1-5) plus prednison 5 mg po twice daily. The treatment cycle is repeated every 35 days.

Detailed Description:

*****UPDATE***** On October 30th, 2007 GPC Biotech announced topline overall survival results for the Phase III trial in hormone refractory prostate cancer-Satraplatin and Prednisone Against Refractory Cancer (SPARC) trial.

The trial evaluated satraplatin plus prednisone versus placebo plus prednisone as a second-line treatment in 950 patients with hormone-refractory prostate cancer (HRPC). The companies reported that the trial did not achieve the endpoint of overall survival (p=0.80, stratified log rank analysis). The median was 61.3 weeks for the satraplatin arm compared to 61.4 weeks for the control group and the hazard ratio was 0.97 (95% CI: 0.83, 1.13). The companies are currently conducting pre-specified subset analyses.

Satraplatin is a member of the platinum-based class of chemotherapy drugs. Platinum-based drugs have been clinically proven to be one of the most effective classes of anticancer therapies. Unlike the currently marketed platinum-based drugs, satraplatin can be given orally.
