A Trial of Intravenous Denileukin Diftitox Plus Subcutaneous Pegylated IFNα-2A in Stage III or IV Ovarian Cancer

March 13, 2018 updated by: The University of Texas Health Science Center at San Antonio

A Phase II Trial of Intravenous Denileukin Diftitox Plus Subcutaneous Pegylated IFNα-2a to Treat Epithelial Ovarian Cancer FIGO Stage III or Stage IV, Extraovarian Peritoneal or Fallopian Tube Carcinoma or Ineligible for First-Line Therapy

This study will test the hypothesis that adding pegylated IFN (IFN)a-2b to denileukin diftitox improves the potential of denileukin diftitox alone to deplete regulatory T cells (Tregs) and will thereby boost tumor immunity in patients with advanced-stage epithelial ovarian cancers, enhancing treatment efficacy.

Detailed Description

The aims of this study are to:

  • Assess the efficacy of adding pegylated IFN-α2b to denileukin diftitox to treat selected advanced-stage epithelial ovarian cancers
  • Test the immune-modulating effects of adding pegylated IFN-α2b to denileukin diftitox in ovarian cancer patients and relate them to clinical efficacy
  • Identify any toxicity associated with pegylated IFN-α2b plus denileukin diftitox treatment in these patients
  • Identify practical means to dose the immunomodulating agents denileukin diftitox and pegylated IFN-α2b based on immunopharmacodynamic metrics

  • No active major medical problems, including untreated or uncontrolled infections
  • Beck Depression Index ≥15 within 30 days of study enrollment
  • If of reproductive potential, a negative urine pregnancy test within 3 days of study enrollment, and agreement to use adequate contraception. Pregnancy testing will continue monthly while on treatment unless the subject is no longer able to become pregnant or there is sufficient justification otherwise

  • No active substance abuse in the prior 6 months
  • Patients failing single agent denileukin diftitox in the ongoing trial "A Phase II Trial of Intravenous Ontak to Treat Epithelial Ovarian Cancer FIGO Stage III or Stage IV, or Extraovarian Peritoneal Carcinoma, Failing or Ineligible for First-Line Therapy" are eligible for this trial provided that three or more weeks have elapsed since their last denileukin diftitox infusion and they meet all eligibility criteria and successfully undergo all screening examinations for this trial.

Exclusion Criteria:

  • Unable to tolerate phlebotomy
  • Germ cell or stromal cell cancers of the ovaries, or other currently uncured cancer
  • Active autoimmune disease including systemic lupus erythematosus, psoriasis, or inflammatory bowel disease that is not medically controlled

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinical Response Rate
Time Frame: every 3 months until the date of first documented progression or date of death from any cause, assessed up to 2 years when study terminated early

Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Response = CR + PR.

Failure to respond criteria are not based on RECIST criteria, which have unclear application to immune-based clinical trials. Instead, novel lack-of-failure criteria, rather than failure-of-success criteria have been written to avoid stopping therapy prematurely without compromising patient safety, to accommodate the uncertainties of assessing failure in this setting. The criteria as written are based on sound medical, scientific and ethical principles. The trial is further designed to help establish the utility of these novel criteria.
