Study type
Description of intervention(s) / exposure
Chemotherapy: Carboplatin given over 6 cycles, 3 weekly.
Intervention code [1] 723 0
Treatment: Drugs
Comparator / control treatment
Flat dose (Arm A) or Intra-patient dose escalation (Arm B). The mode of administration is intravenous infusion. Each treatment cycle involves a single dose performed at the start of 3 week periods for a total of 6 cycles. The dose of Carboplatin in both arms for cycle 1 will be dosed to Area Ander Curve (AUC) of 6. Dose escalation in Arm B will be based on the nadir count from the previous cycle. Doses will increase by either 10 or 20% depending on the blood counts.
