Study Description

Brief Summary:

The purpose of this study is to determine if weekly chemotherapy (i.e. giving paclitaxel or carboplatin at a lower dose every week) is more effective than standard chemotherapy (paclitaxel and carboplatin given once every three weeks over 18 weeks) in treating ovarian cancer. The investigators also want to see if weekly chemotherapy causes more or fewer side-effects than standard chemotherapy.

Condition or disease	Intervention/treatment	Phase
Ovarian Cancer	Drug: Carboplatin; Drug: Paclitaxel	Phase 3

Detailed Description:

ICON8 is a three-arm, three stage trial. Patients will be randomised in a 1:1:1 ratio. Patients in arm 1 (control arm) will receive weekly carboplatin and paclitaxel on day 1 of a 21-day cycle for 6 cycles. Patients in arm 2 will receive carboplatin on day 1 and dose-fractionated weekly paclitaxel on day 1, 8 and 15 of a 21-day cycle for 6 cycles. Patients in arm 3 will receive dose-fractionated weekly carboplatin and dose-fractionated weekly paclitaxel on day 1, 8 and 15 of a 21-day cycle for 6 cycles.

The trial will have three planned stages. Stage 1 will be conducted to confirm feasibility and safety of protocol treatment in all patients and separately in the Delayed Primary Surgery (DPS) patients. The outcome measure for stage 2 will be 9-month progression-free survival (PFS) rate. The primary outcome measures for stage 3 will be PFS and overall survival and secondary outcomes will be toxicity, Quality of Life and Health Economics. If pre-defined levels of deliverability, at stage 1, or activity, at stage 2, are not met then the research arms will be reconsidered.

Outcome Measures

Primary Outcome Measures :

1. Stage 1: Feasibility assessed as the number of cycles and dose intensity of protocol treatment delivered per patient. [ Time Frame: 6 months after the 50th patient has been randomised to each arm and 6 months after the 50th patient with a plan to undergo delayed primary surgery has been randomised to each arm ]
2. Stage 1: Safety assessed as the rate of any ≥ grade 3 toxicity experienced per patient. [ Time Frame: 6 months after the 50th patient has been randomised to each arm and 6 months after the 50th patient with a plan to undergo delayed primary surgery has been randomised to each arm ]
3. Stage 2: Progression Free Survival rate at 9 months after randomisation [ Time Frame: 9 months after first 62 patients randomised per arm ]
4. Stage 3: Progression Free Survival [ Time Frame: PFS expected 1 year after last patient is randomised. OS expected 3 years after last patient is randomised. ]
5. Stage 3: Overall Survival [ Time Frame: PFS expected 1 year after last patient is randomised. OS expected 3 years after last patient is randomised. ]

Secondary Outcome Measures :

1. Stage 3: Toxicity assessed by number of participants with adverse events [ Time Frame: Expected 1 year and 3 years after last patient is randomised. ]
   Assessment of toxicity profile of dose-fractionated chemotherapy
2. Stage 3: Quality of Life [ Time Frame: Expected 1 year and 3 years after last patient is randomised. ]
   Assessment of potential impact of dose-fractionated chemotherapy on functionality and well-being in patients undergoing first line treatment for ovarian cancer.
3. Stage 3: Health Economics [ Time Frame: Expected 1 year and 3 years after last patient is randomised. ]

Criteria

• Confirmed high-risk histological subtype for patients with FIGO stage IC/IIA disease, namely:

  • High grade serous carcinoma
  • Clear cell carcinoma
  • Other histological subtype considered poorly differentiated/grade 3

• Adequate liver function (within 28 days prior to randomisation):

  • Serum bilirubin (BR) ≤ 1.5 x ULN
  • Serum transaminases ≤ 3 x ULN in the absence of parenchymal liver metastases or ≤ 5 x ULN in the presence of parenchymal liver metastases
• Adequate renal function as defined by GFR (Glomerular Filtration Rate) ≥ 30ml/min.
