Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

682 participants in 2 patient groups

Control Arm

No Intervention group

Description:

Patients receive bevacizumab 15 mg/kg iv on day 1 followed by gemcitabine 1000mg/m² iv on day 1 \& 8 and carboplatin AUC4 iv on day 1 every 3 weeks for up to 6 cycles in the absence of progression disease or unacceptable toxicities. Patients then continue to receive bevacizumab 15 mg/kg iv every 3 weeks until progression disease or unacceptable toxicities.

Research Arm

Experimental group

Description:

Patients receive bevacizumab 10 mg/kg iv on day 1 \& 15 followed by PLD 30mg/m² iv on day 1 carboplatin AUC4 iv on day 1 every 4 weeks for up to 6 cycles in the absence of progression disease or unacceptable toxicities. Patients then continue to receive bevacizumab 15 mg/kg iv every 3 weeks until progression disease or unacceptable toxicities.

Treatment:

Drug: Carboplatin

Drug: PLD
