A Trial of Intravenous Denileukin Diftitox in Stage III or IV Ovarian Cancer (ONTAK)

February 27, 2018 updated by: The University of Texas Health Science Center at San Antonio

A Phase II Trial of Intravenous Ontak to Treat Epithelial Ovarian Cancer FIGO Stage III or Stage IV, or Extraovarian Peritoneal Carcinoma, of Fallopian Tube Carcinoma Failing or Ineligible for First-Line Therapy

This study tests whether denileukin diftitox will deplete regulatory T cells, boost tumor-specific immunity and treat epithelial ovarian cancer in patients who have failed, or who are ineligible for front line therapy.

Detailed Description

This is a non-randomized, single-arm, Phase II trial. Selected patients with advanced-stage epithelial ovarian cancers who have no reasonable chance of cure using standard regimens, or who will not receive such regimens (due to contraindication or intolerance) are eligible. Patients will be treated with Ontak at 12 µg/kg monthly as long as they meet response criteria.
