简要总结
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.
详细描述
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.

入选标准
- •Females aged 18 years or more
- •Signed informed consent and ability to comply with the protocol
- •Histologically confirmed, with core biopsy from a disease site as minimum requirement (cytology alone is insufficient for diagnosis):
- •Epithelial ovarian carcinoma
- •Primary peritoneal carcinoma of Müllerian histological type
- •Fallopian tube carcinoma
- •FIGO stage IC or above, which may be based on clinical and radiological assessment in patients who have not undergone immediate primary surgery
- •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
- •ECOG Performance Status (PS) 0-2
- •Life expectancy > 12 weeks
- •Adequate bone marrow function:
- •Absolute Neutrophil Count (ANC) ≥ 1.5 x 109/l
- •Platelets (Plt) ≥ 100 x 109/l
- •Haemoglobin (Hb) ≥ 9g/dl (can be post transfusion)
- •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.
排除标准
- •Non-epithelial ovarian cancer, including malignant mixed Müllerian tumours (carcinosarcomas)
- •Peritoneal cancer that is not of Müllerian origin, including mucinous histology
- •Borderline tumours (tumours of low malignant potential)
- •Prior systemic anti-cancer therapy for ovarian cancer (for example chemotherapy, monoclonal antibody therapy, tyrosine kinase inhibitor therapy or hormonal therapy)
- •Previous malignancies within 5 years prior to randomisation apart from: adequately treated carcinoma in-situ of the cervix, breast ductal carcinoma in-situ, non-melanomatous skin cancer; or previous/synchronous early-stage endometrial cancer defined as stage IA (FIGO 2009) grade 1 or 2 endometrioid cancers with no lymphovascular space invasion
- •Pre-existing sensory or motor neuropathy grade ≥ 2
- •Evidence of any other disease/metabolic dysfunction that in the opinion of the investigator would put the subject at high-risk of treatment-related complications or prevent compliance with the trial protocol
- •Planned intraperitoneal cytotoxic chemotherapy
- •Any previous radiotherapy to the abdomen or pelvis
- •Sexually active women of childbearing potential not willing to use adequate contraception (e.g. oral contraceptives, intrauterine device or barrier method of contraception in conjunction with spermicidal jelly or surgically sterile) for the study duration and at least six months afterwards
- •Pregnant or lactating women
- •Treatment with any other investigational agent prior to protocol defined progression
- •Known hypersensitivity to carboplatin, paclitaxel or their excipients (including cremophor)
- •History or clinical suspicion of brain metastases or spinal cord compression. CT/MRI of the brain is mandatory in the case of suspected brain metastases. Spinal MRI is mandatory in the case of suspected spinal cord compression. Patients with brain or meningeal metastases are not eligible
