Allocation: RANDOMIZED | Intervention model: FACTORIAL
Enrollment: 241
Healthy volunteers: no

Brief summary:
Multi-center, randomized Phase III study. 4 arms. 360 Patient to enroll. Purpose is evaluate time to progression disease (PD).

Detailed description:

Arms:
arm 1: Docetaxel and Gemcitabine (Tri-weekly) arm 2: Paclitaxel and Gemcitabine (Tri-weekly) arm 3: Docetaxel and Gemcitabine (Weekly) arm 4: Paclitaxel and Gemcitabine (Weekly)

Interventions: intervention 1: Gemcitabine intervention 2: Docetaxel intervention 3: Paclitaxel
Intervention descriptions: intervention 1: Arm A: 1000 mg/m², 30 minute (min) intravenous (IV) infusion on Days 1 and 8, repeated every 21 days for 10 cycles for complete responders (CRs=disappearance of all target lesions) or partial responders (PRs≥30% decrease in sum of longest diameter of target lesions); 6 cycles for stable disease (SD=small changes that do not meet the above criteria); or until progressive disease (PD≥20% increase in sum of longest diameter of target lesions).

Arm B: 1250 mg/m², 30 min IV infusion on Days 1 and 8, repeated every 21 days for 10 cycles for CRs or PRs; 6 cycles for SD; or until PD.

Arm C: 800 mg/m², 30 min IV infusion on Days 1, 8, and 15 repeated every 21 days for 10 cycles for CRs or PRs; 6 cycles for SD; or until PD.

Arm D: 800 mg/m², 30 min IV infusion on Days 1, 8, and 15 repeated every 28 days for 10 cycles for CRs or PRs; 6 cycles for SD; or until PD. intervention 2: Arm A: 75 milligram per square meter (mg/m²), 60 min IV infusion on Day 1 only, to be given 30 min prior to Gemcitabine, repeated every 21 days (tri-weekly) for 10 cycles for CRs or PRs; 6 cycles for SD; or until PD.

Arm C: 30 mg/m², 30-60 min IV infusion on Days 1, 8, and 15, to be given 30 min prior to Gemcitabine, repeated every 28 days (weekly) for 10 cycles for CRs or PRs; 6 cycles for SD; or until PD. intervention 3: Arm B: 175 mg/m², IV infusion over approximately 3 hours, followed by Gemcitabine, on Day 1, repeated every 21 days (tri-weekly) for 10 cycles for CRs or PRs; 6 cycles for SD; or until PD.

Arm D: 80 mg/m², IV infusion over approximately 1 hour, Days 1, 8, and 15, followed by Gemcitabine, repeated every 28 days (weekly) for 10 cycles for CRs or PRs; 6 cycles for SD; or until PD.
