Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Have recurrent epithelial ovarian cancer, primary peritoneal carcinomatosis or fallopian tube cancer. - Have platinum-resistant (recurrence within 6 months of a platinum-containing regimen) or platinum refractory (progression while on platinum) disease - Have measurable disease according to RECIST or detectable disease. o Measurable disease is defined as the presence of at least one uni-dimensionally measurable lesion greater than or equal to 20 mm by conventional techniques, including palpation, plain x-ray, CT scan or MRI, or greater than or equal to 10 mm by spiral CT scan. o Detectable disease is defined in a patient as one who does not have measurable disease but has at least one of the following conditions: 1) Baseline values of cancer antigen 125 (CA-125) at least twice the upper limit of normal; 2) Ascites and/or pleural effusion attributed to tumor; 3) solid and/or cystic abnormalities on radiographic imaging that do not meet RECIST definitions for target lesions. - >/= 18 years of age. - Give written, informed consent for participation in the protocol. - Be at least 4 weeks from last treatment to allow recovery from prior toxicity (with the exception of hormonal therapy, where a 1-week wash-out period and radiation therapy where a 3-week wash-out period are sufficient). Patients coming off experimental therapy with biological agents not expected to cause myelotoxicity should have been off treatment for at least 3 weeks as wash-out period. - Have had disease that has progressed within 6 months platinum-based chemotherapeutic regimen. - Have no history of platinum allergy. - Have a negative serum pregnancy test prior to the study entry and be practicing an effective form of contraception if hysterectomy and/or oophorectomy were not part of the prior treatment. It is expected that the overwhelming majority of ovarian cancer patients would have had hysterectomy and oophorectomy as part of the original surgery. - Have Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. - Have acceptable organ function, as evidenced by laboratory data: o Aspartate aminotransferase and alanine aminotransferase less than 2.5 times upper limit of normal (ULN) o Direct bilirubin less than 1.5 times ULN o Alkaline phosphatase less than 2.5 times ULN o Absolute neutrophil count greater than or equal to 1500 cells/mm3 o White cell blood count greater than 3000cells/mm3 o Hemoglobin greater than or equal to 9.0 g/dL (can be post-transfusion) o Platelets greater than 100,000/mm3 (can not be post-transfusion) o Creatinine levels less than 1.5 times ULN

Who cannot join

  • Not have participated in any clinical trial involving conventional or investigational drugs or devices within the previous 3 weeks. - Not have grade 2 or greater neuropathy. - Have no additional active cancer in addition to the epithelial ovarian cancer within the last 5 years, with the exception of superficial skin cancer (basal cell or squamous cell skin carcinoma), carcinoma in situ of the cervix, Stage I endometrial cancer with less than 50% invasion of the myometrium, or other adequately treated Stage I or II cancer in complete remission. - Be free of active infection requiring antibiotic treatment. - Not have an additional uncontrolled serious medical condition or psychiatric illness. - Not have an immune deficiency and be receiving combination anti-retroviral therapy - Not have known brain metastases, as progressive neurologic dysfunction may develop, that would confound the evaluation of neurologic and other adverse events. - Absence of uncontrolled hypertension, arrhythmia, congestive heart failure or angina. Patients who have had a myocardial infarction or cardiac surgery should be at lease 6 months from the event and free of active symptoms.

About this study

Official title: Phase I/II Trial of Decitabine as a Sensitizer to Carboplatin in Platinum Resistant Recurrent Ovarian Cancer

Based on these pre-clinical data, which were generated by our group, the investigators propose to test in a phase I/II clinical trial the following hypothesis: demethylation induced by decitabine results in re-sensitization to platinum in recurrent ovarian cancer.

To test this hypothesis, the investigators will treat patients with recurrent ovarian cancer platinum resistant (recurrence within 6 months from platinum therapy) or platinum-refractory (no response to platinum) with a combination consisting of decitabine and carboplatin.

This will be an institutional open label phase I/II trial to determine the safety and the biologic activity of the Decitabine/Carboplatin combination.

The investigators will determine whether Carboplatin can be safely combined with Decitabine, the optimal dose schedule and the investigators will define whether at this dosage, the regimen is biologically active (i.e. induces demethylation of target genes).

In the second part of the trial, the investigators will determine the clinical activity of the combination in a population of patients with platinum-resistant ovarian cancer.

Read the detailed description

Decitabine at escalating dose levels will be given IV X 5 days followed by Carboplatin given IV on Day 8 at a dose corresponding to an area under curve (AUC) of 5. The maximum dose of Decitabine (20 mg/m2) is based on the results of the myelodysplastic syndrome (MDS) clinical trial that demonstrated biological and clinical efficacy at this dose (15-17). It is recognized that higher doses of decitabine can be administered, myelotoxicity being the most significant adverse event. This protocol will assess the lower less toxic but biologically active dose.

Decitabine dose will be escalated as follows.

Dose level -1: 5 mg/m2 IV per day (QD) X 5 days Dose level 1: 10mg/m2 IV QD X 5 days Dose level 2: 20mg/m2 IV QD X 5 days

Each cycle will consist of 28 days, with delays to allow blood count recovery. Correlative blood draws will occur on Day1 (baseline) and on Day 8 before Carboplatin for cycle 1 and 2.

The escalation phase will follow the standard 3+3 design. That is, patients will be accrued to each dose level in cohorts of up to 3-6 patients. Escalation will continue until a DLT is observed, the highest dose-level is reached, or medical judgment indicates. The goal of the phase I cohort is to ensure the safety and tolerability of the combination, not to define the maximum tolerated dose.

An initial 3 patients will be enrolled at dose level 1. If all 3 patients in dose level 1 complete 4 weeks of therapy without dose limiting toxicity (DLT), the study will proceed to enroll 3 patients at dose level 2. If all 3 patients in dose level 2 complete 4 weeks of therapy without DLT, we will accrue 3 more to ensure that only 0 or 1 of 6 have a DLT and then proceed to the phase II cohort. As dose level 2 represents full doses of both agents, there will be no further dose escalation beyond dose level 2.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase I: Maximum Tolerated Dose (MTD) for Use in Phase II

    The definition of MTD will follow the standard definition of the phase I 3+3 trial concept. Dose Limiting Toxicities (DLTs) will be scored in the first cycle. Patients will be monitored for 28 days (a cycle) to determine whether a DLT is experienced for the specific dose level.

    Measured: 28 days

  2. Phase II: Percent of Patients With Objective Response

    The percent of patients having an objective response (Complete Response or Partial Response) will be estimated with a 95% exact binomial confidence interval for the percent of patients receiving drug.

    Measured: screening until end of study (approx 12-18 months)

Secondary outcomes (2)
  1. Phase II: Percent of Patients With Objective Response, CA125 Response or Stable Disease > 3 Months

    The percent of patients having an objective response (Complete Response or Partial Response) or CA125 response (Complete Response or Partial Response) or stable disease > 3 months will be estimated with a 95% exact binomial confidence interval for the percent of patients receiving drug.

    Measured: screening until end of study (approx 12-18 months)

  2. Phase II: Progression Free Survival

    Progression free survival times will be estimated using the Kaplan-Meier method. If a patient progresses or dies, the time till that event will be used. If a patient does not progress or die on the study, the patient will be censored at the last available visit. Confidence intervals on the median will be constructed.

    Measured: Baseline until disease progression or last visit

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Sep 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase I: Maximum Tolerated Dose (MTD) for Use in Phase II (time frame: 28 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00477386, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2014; AzTrials last refreshed its copy on 8 Nov 2026.
