Decitabine and Selinexor in Combination to Reverse Drug Resistance With Standard Chemotherapy in Ovarian Cancer

Participants enrolled in this study protocol will receive therapy with decitabine followed by usual doses of carboplatin and paclitaxel for one cycle. If the participant tolerates this well, the selinexor will be added to the second and subsequent cycles of therapy given at 4-week intervals, in the out-patient setting. The participant will be asked to complete 9 study visits during their active therapy during each cycle: Days 1-5 of each cycle the participant will receive decitabine treatments over 1 hour, with carboplatin and paclitaxel given on day 6. Paclitaxel alone will continue weekly for 3 weeks on days 13, 20 and 27 of the 28-day cycle. The 5 days of daily decitabine therapy lasts about 1 hour and the carboplatin and paclitaxel treatment last 4 hours, with single agent paclitaxel being only 1 hour. Selinexor is not added until cycle 2 and is given orally weekly on days 7, 14, 21, and 28 of the 28-day cycle. Weekly clinic visits are required for the first two cycles at the time paclitaxel is administered. The participant's progress will be assessed and if a remission is achieved the participant would continue the therapy for up to 6 cycles.
