Brief Summary

Multicenter Phase II study on Decitabine-Carboplatin combination in platinum resistant ovarian cancer patients.

Patients will receive study treatment until disease progression is documented, extraordinary medical circumstances occur, intolerable toxicities occur, or the patient withdraws consent.

Detailed Description

This is an open-label, prospective, multicenter, randomized Phase II, clinical trial evaluating the efficacy and safety of Decitabine-Carboplatin combination in recurrent, platinum resistant ovarian cancer patients in comparison to physician' choice chemotherapy:

Arm A: Carboplatin AUC (Area Under Curve) 5 d 8 q 28 Plus Decitabine 10 mg/mq iv d1-5 q 28

Arm B: Pegylated Liposomal Doxorubicin 40 mg/mq q 28 or Gemcitabine 1000 mg/mq dd 1, 8, 15 q 28 or Weekly Paclitaxel 80 mg/mq gg 1, 8, 15 q 28

Patients will be randomly assigned in a 1:1 ratio to treatment arms.

Exclusion Criteria

• Pregnant (potentially fertile patients must use contraceptive measures to avoid pregnancy during and for at least 3 months after study participation and must have a negative serum pregnancy test at baseline).
• Patients should not be breast-feeding during treatment and for 2 months following the end of treatment.
• Serious heart disease, including heart failure, atrio-ventricular block of any degree, serious arrhythmia or history of any one or more of the following cardiovascular conditions within the past 6 months: cardiac angioplasty or stenting, myocardial infarction, unstable angina, symptomatic peripheral vascular disease, coronary artery by-pass graft surgery, class II, III or IV congestive heart failure as defined by the New York Heart Association (NYHA)

• History of cerebrovascular accident, pulmonary embolism or untreated deep venous thrombosis (DVT) within the past 6 months
• History of human immunodeficiency virus (HIV) infection or chronic hepatitis B or C.
• Patients who had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent. Note: Subjects with < Grade 2 neuropathy or ≤ Grade 2 alopecia are an exception to this criterion and may qualify for the study.
• Patients with evidence of interstitial lung disease.
• Major surgical procedure, open biopsy, or significant traumatic injury within 3 weeks prior to beginning therapy, or anticipation of the need for a major surgical procedure during the course of the study; minor surgical procedures such as fine needle aspiration or core biopsy within 1 week prior to beginning therapy are also excluded.
• Known hypersensitivity to the study drugs or to drugs with similar chemical structures.
• Concurrent treatment with other experimental drugs.
• Participation in another clinical trial with any investigational drug within 30 days prior to study screening.

Primary Outcome Measures

Name	Time	Method
Progression free survival (PFS)	from randomization to the date of radiological/clinical progression of disease or death, assessed up to 3 years	The primary objective is to compare Decitabine plus Carboplatin combination versus physician' choice chemotherapy in terms of progression free survival

Secondary Outcome Measures

Name	Time	Method
Duration of response	3 years	Duration of response
Overall survival (OS)	from randomization to the date of death, assessed up to 3 years	The secondary objective is to compare Decitabine plus Carboplatin combination versus physician' choice chemotherapy in terms of overall survival
Radiological response rate (in patients with measurable disease)	3 years	Radiological response rate
Cancer-Antigen 125 (CA-125) response rate per GCIG (Gynaecologic Cancer Intergroup) and change in CA-125	3 years	Serum level of CA125 is used to monitor response to chemotherapy, relapse, and disease progression in ovarian cancer patients.
Toxicity profile	3 years	Incidence of adverse events
Patient Reported Outcome: Physical well-being	3 years	will be evaluated using the Functional Assessment of Cancer Therapy (FACT-O) and FACT-O Ovarian Cancer-specific Subscale (OCS) questionnaire. The total scores of both scales will be calculated, the scores of each question at each time point and their difference from baseline will be summarized for each treatment group. At a given visit, the change and/or percent change from baseline will be compared between the randomized treatment groups using an ANCOVA test using the treatment as a categorical factor and baseline measurement for the parameter as a continuous covariate.; The time to an event in PRO (Patient Reported Outcome) of worsening of disease symptoms will be defined as the time from randomization to a 4-point reduction in the FACT-O questionnaire. Patients without a 4-point reduction will be censored on the date of their last PRO evaluation. Patients that do not have both a baseline measurement and at least one post-baseline measurement will not be included.
