About this study

Official title: Phase I Dose Escalation Study of Intraperitoneal (I.P.) ONTAK® Administered to Patients With Advanced Stage Ovarian Cancer

RATIONALE: Biological therapies, such as denileukin difitox, may stimulate the immune system in different ways and may prevent tumor cells from growing. PURPOSE: This phase I trial is studying the side effects and best dose of denileukin diftitox in treating patients with advanced refractory ovarian cancer, primary peritoneal carcinoma, or epithelial fallopian tube cancer.

Read the detailed description

PRIMARY OBJECTIVES: I. To estimate the maximum tolerated dose of intraperitoneal administration of ONTAK. SECONDARY OBJECTIVES: I. To evaluate the change in the number of Tregs in the peritoneum with the administration of ONTAK. II. To evaluate the change in the number of Tregs in the peripheral blood with the administration of ONTAK. III. To assess the clinical impact of ONTAK on tumor burden by serial measurements of CA-125. IV. To assess the level of circulating cytokines IL-2, IL-6, IL-10, TGF-beta2, and TNF-alpha in the peritoneum and peripheral blood before and after I.P. ONTAK. OUTLINE: This is a dose escalation study. Patients receive intraperitoneal denileukin diftitox over at least 15 minutes on days 1-3. Treatment repeats every 14 days for 4 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of denileukin diftitox until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. After the completion of study treatment, patients are followed up at 1 and 2 weeks, monthly for 3 months, and then at 6 months.

Being tested
denileukin diftitox, intraperitoneal administration, laboratory biomarker analysis, enzyme-linked immunosorbent assay, flow cytometry

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • denileukin diftitoxBiological

    Also called DAB389 interleukin-2, DAB389 interleukin-2 immunotoxin, DAB389-IL2, DAB389IL-2

    Given IP at 3 dose levels: 5mcg/kg of ONTAK, 15mcg/kg of ONTAK, or 25mcg/kg of ONTAK

  • intraperitoneal administrationProcedure or surgery

    After completion of I.P. normal saline infusion, the I.P. catheter will be capped and patients will be turned/rotated for 1 hour to help facilitate I.P. bathing w/ONTAK; patients will be turned/rotated every 15 minutes in 4 different positions for a total of 1 hour

What is being measured

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

  1. Safety and toxicity profile as assessed by the Cancer Therapy Evaluation Program, Common Terminology Criteria for Adverse Events version 3.0

    Measured: From baseline

  2. MTD

    Measured: From baseline

Secondary outcomes (3)

  1. Efficacy of ONTAK defined as a 25% reduction in the number of Tregs in either the peripheral blood and/or in the peritoneal cavity

    Measured: From baseline

  2. Clinical impact on course of disease as assessed by serum CA-125 measurements

    Measured: At baseline and at months 1, 2, 3, and 6

  3. Changes in circulating cytokines IL-2, IL-6, IL-10, TGF-beta2, and TNF-alpha in the peripheral blood and at the site of disease as measured by ELISA

    Measured: Pre- and post-treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing denileukin diftitox, intraperitoneal administration and laboratory biomarker analysis in people with Fallopian Tube Cancer and Ovarian Clear Cell Cystadenocarcinoma, run by University of Washington at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 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.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Safety and toxicity profile as assessed by the Cancer Therapy Evaluation Program, Common Terminology Criteria for Adverse Events version 3.0 (time frame: From baseline). 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 NCT00357448, which also lists 1 linked publication.

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 14 May 2019; AzTrials last refreshed its copy on 7 Nov 2026.
