Trial of Decitabine as a Sensitizer to Carboplatin in Platinum Resistant Recurrent Ovarian Cancer

Summary

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.
