Response using Response Evaluation Criteria In Solid Tumors (RECIST) criteria. Complete Response=disappearance of all target lesions; Partial Response=30% decrease in sum of longest diameter of target lesions; Progressive Disease=20% increase in sum of longest diameter of target lesions; Stable Disease=small changes that do not meet above criteria.

Number of all randomized participants.

TTTF event was defined as documented disease progression, death on study, start of non-protocol-specified anticancer therapy, or therapy discontinuation due to toxicity. TTTF for patients who were still participating in study without treatment failure at time of analysis were treated as censored at date of last tumor assessment. TTTF for patients who had discontinued from therapy for reasons other than toxicity and who did not experience treatment failure prior to therapy discontinuation were treated as censored on day of study discontinuation.

Number of randomized patients. Censored patients: Gemcitabine + Paclitaxel = 34; Gemcitabine + Carboplatin = 26; Gemcitabine + Cisplatin = 30.

PFS was defined as the time from randomizaton to the date of documented disease progression or death on study, whichever occurred first. PFS for participants who discontinued from the study or who had not progressed at the time of analysis were treated as censored at the date of the last tumor assessment.

Number of randomized patients. Censored patients: Gemcitabine + Paclitaxel = 20; Gemcitabine + Carboplatin = 18; Gemcitabine + Cisplatin = 28.

Duration of response was measured from time of first documentation of complete response (disappearance of all target lesions) or partial response (30% decrease in sum of longest diameter of target lesions), until date of PFS. Duration of response was censored on day of last tumor assessment for patients who had not progressed or who had discontinued study at time of analysis, and for cases where investigator determined patient had progressive disease and discontinued study therapy and/or started a new, non-protocol-specified anti-cancer therapy before documented disease progression.

Randomized patients who had either a complete response or partial response. Censored patients: Gemcitabine + Paclitaxel = 4; Gemcitabine + Carboplatin = 4; Gemcitabine + Cisplatin = 14.

Overall survival time is defined as the time from the date of randomization to date of death due to any cause. Survival time is censored at the date of last contact for patients who are still alive or lost to follow-up.

Number of randomized patients. Censored patients: Gemcitabine + Paclitaxel = 23; Gemcitabine + Carboplatin = 24; Gemcitabine + Cisplatin = 22.
