A Phase II, Multi-Center, Open-Label, Uncontrolled Study to Evaluate the Efficacy and Safety of Sorafenib Given Daily in Combination With Repeated 21-Day Cycles of Dacarbazine (DTIC) Chemotherapy in Subjects With Advanced Metastatic Melanoma

Best Overall Response (BOR): Best tumor response achieved during or within 30 days after active therapy confirmed according to the Response Evaluation Criteria in Solid Tumors (RECIST). Complete response (CR): The disappearance of all target and non-target lesions. Partial response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. SD was defined as steady state of disease, PD was defined as an increase of at least 20% increase in the sum of the LD of target lesions or appearance of new lesions.

Progression-free Survival (PFS) was the time from the first dose of combination therapy to disease progression (radiological or clinical, whichever is earlier) or death (if death occurs before progression is documented). PFS for subjects without tumor progression or death at the time of analysis were censored at the date of last tumor evaluation.

Progression-free Survival (PFS) was the time from the first dose of combination therapy to disease progression (radiological or clinical, whichever is earlier) or death (if death occurs before progression is documented). PFS for subjects without tumor progression or death at the time of analysis were censored at the date of last tumor evaluation.

Overall Survival was the number of days from the date that combination treatment started until the date of death.

Duration of Response was assessed in subjects who showed a Partial Response (PR) or Complete Response (CR). It was defined as the time from the first documented objective response to Progressive Disease (PD), or death if before documented progression. Duration of response for subjects who have not progressed or died at the time of analysis was censored at the date of last tumor assessment.

Duration of complete response was the number of days from the date that a complete response was first documented to the date that recurrent or progressive disease was first objectively documented (if patient progressed then censored=no) or to last observation (if patient did not progress then censored=yes).

Duration of partial response was the number of days from the date that a partial response was first documented to the date that recurrent or progressive disease was first objectively documented (if patient progressed then censored=no) or to last observation (if patient did not progress then censored=yes).

DC was defined as the total number of subjects whose best response was not progressive disease (PD) (total number of CRs + total number of PRs + total number of Stable Diseases (SD)). The DC at specific time points could also be calculated as the total number of subjects whose response was not PD at that time point.

Duration of Stable Disease (DSD), defined as the time from the first documented objective evidence of Stable Disease (SD) to disease progression (DP) or death if death occurred before DP, was assessed in subjects who showed SD as best response. DSD for subjects who had not progressed or died was censored at the date of last tumor assessment.

Time to Response in subjects who achieved an objective response (PR or CR with confirmation) was measured from the date of starting study combination treatment until the earliest date that the response was first documented.

Time to Progression was the number of days from the start of therapy to progression (if patient progressed then censored=no) or to the last observation at which the patient was known to have not progressed, that is, the last observation with a best response of CR, PR, or SD.
