Ontak (Denileukin Diftitox) - Summary

 



ONTAK SUMMARY

ONTAK® (denileukin diftitox), a recombinant DNA-derived cytotoxic protein composed of the amino acid sequences for diphtheria toxin fragments A and B (Met1-Thr387)-His followed by the sequences for interleukin-2 (IL-2; Ala1-Thr133), is produced in an E. coli expression system.

ONTAK is indicated for the treatment of patients with persistent or recurrent cutaneous T-cell lymphoma whose malignant cells express the CD25 component of the IL-2 receptor (See PRECAUTIONS, Laboratory Tests for CD25 expression testing). The safety and efficacy of denileukin diftitox in patients with CTCL whose malignant cells do not express the CD25 component of the IL-2 receptor have not been examined.

The US Food and Drug Administration (FDA) has approved a new drug for treating patients with the rare white blood cell cancer Cutaneous T-cell Lymphoma (CTCL); the drug Istodax (romidepsin) is injectable and is marketed by Gloucester Pharmaceuticals Inc of Cambridge, Massachusetts. Every year, about 1,500 Americans are newly diagnosed with CTCL, a type of non-Hodgkin's lymphoma.

Quality-of-life improvements in cutaneous T-cell lymphoma patients treated with denileukin diftitox (ONTAK). [2002.03]
Cutaneous T-cell lymphoma (CTCL) can be associated with painful, pruritic, disfiguring lesions. As part of a multicenter, randomized phase III trial in patients with heavily pretreated advanced and/or recurrent CTCL, the effects of an interleukin-2 receptor-targeted fusion protein, denileukin diftitox (DAB389IL-2, ONTAK), on patient-rated overall quality of life (QOL), skin appearance, and pruritus severity were evaluated...

Pivotal phase III trial of two dose levels of denileukin diftitox for the treatment of cutaneous T-cell lymphoma. [2001.01.15]
PURPOSE: The objective of this phase III study was to determine the efficacy, safety, and pharmacokinetics of denileukin diftitox (DAB389IL-2, Ontak [Ligand Pharmaceuticals Inc, San Diego, CA]) in patients with stage Ib to IVa cutaneous T-cell lymphoma (CTCL) who have previously received other therapeutic interventions... CONCLUSION: Denileukin diftitox has been shown to be a useful and important agent in the treatment of patients whose CTCL is persistent or recurrent despite other therapeutic interventions.

Clinical Trials Related to Ontak (Denileukin Diftitox)

Study of ONTAKŪ to Treat Cutaneous T-Cell Lymphoma (CTCL) [Completed]
The purpose of this research study is to evaluate how effective ONTAK is in the treatment of cutaneous T-cell Lymphoma (CTCL) and determine whether the presence of a type of protein called CD25 on the cancer cells makes a difference in how the body responds to the treatment.

The hypothesis is that there is no difference in response rate for patients whose tumor cells are CD25 positive or negative.

Ontak (Denileukin Diftitox) in Patients With SM [Completed]
Primary Objective:

1. To assess the response rate of ONTAK in Systemic Mastocytosis (SM) patients.

Secondary Objectives:

1. To assess the safety of ONTAK in SM patients.

2. To evaluate the time to progression and duration of response following treatment with ONTAK.

A Study of ONTAK and CHOP in Newly Diagnosed, Peripheral T-Cell Lymphoma [Active, not recruiting]
Study of ONTAK and CHOP (chemotherapy drugs) to find out their ability to make Peripheral T-cell lymphoma disappear (for any period of time) and potentially lengthen life. The study will also compare what kind of side effects these drugs cause and how often they occur. The hypothesis is that patients with newly diagnosed peripheral T-Cell lymphoma, when given ONTAK + CHOP, will tolerate the treatment and will have a 20% improvement in response rate when compared to CHOP alone.

A Study of ONTAK in Patients With Advanced Refractory Breast Cancer [Recruiting]
This is a phase I-II single arm (no placebo, no randomization) study in patients with advanced stage breast cancer whose disease has progressed or relapsed following standard therapy. Patients will receive intravenous ONTAK, an agent that we hypothesize may have anti-tumor activity in certain breast cancers, for 5 consecutive days every 21 days. A maximum of 6 cycles may be administered. Up to 20 patients will be accrued to this study.

Combination of Etanercept, Mycophenolate Mofetil (MMF), Denileukin Diftitox (Ontak), and Pentostatin With Steroids [Active, not recruiting]
Primary Objective:

1. To estimate the proportion of CR at Day 28 of therapy for newly diagnosed acute GVHD for each of these agents given in combination with corticosteroids.

Secondary Objectives:

1. To determine:

1. proportion of partial response (PR), mixed response and progression at Day 28

2. proportion of treatment failure (no response, progression, or mortality) by Day 14

3. the incidence of GVHD flares requiring increasing therapy before Day 90.
