Pegasys in Patients With Chronic Myeloid Leukemia (CML)

Brief Summary:

The goal of this clinical research study is to learn if adding pegylated interferon-alfa 2a (Pegasys) to the TKI that you are already receiving can help to control CML. The safety of this treatment combination will also be studied.

Pegasys is a form of the drug interferon. It is designed to help the body's immune system to fight infections. It may also affect the body's response to cancer.

A TKI (imatinib mesylate, nilotinib, or dasatinib) is designed to bind to and shut off a protein in tumor cells called Bcr-Abl. Shutting Bcr-Abl off may prevent CML cells from growing, and may cause them to die.

You are already receiving a TKI. This consent form will describe the administration of Pegasys, any tests and procedures that need to be performed while you are receiving Pegasys, and any risks/benefits there may be from receiving Pegasys.

Condition or disease Intervention/treatment Phase
Leukemia Drug: PEG-IFNá-2a Phase 2

Detailed Description:

Study Drug Administration:

If you are found to be eligible to take part in this study, you will receive Pegasys through a needle under the skin 1 time each week while you are on study. You will be taught how to use the study drug at the first visit and will administer it to yourself at all future doses.

You will continue receiving the TKI you are already taking at the dose and frequency you have been receiving it when you began taking part in this study.

Study Visits:

At every study visit, you will be asked about any side effects you may have had and to list any drugs you may be taking.

Every 1-2 weeks for 8 weeks, then every 6-8 weeks after that, blood (about 1-2 teaspoons) will be drawn for routine tests.

Every 3 months for 6 months, then every 6-12 months after that, you will have a complete physical exam, including measurement of your vital signs.

Every 3-6 months for 1 year, you will have a bone marrow aspirate to check the status of the disease and to check for changes in your chromosomes.

Every 3-6 months for 1 year, then every 6-12 months after that, blood (about 1 teaspoon) will be drawn to check the levels of leukemia in the blood.

Length of Study:

You may continue taking Pegasys for as long as the doctor thinks it is in your best interest. You will no longer be able to take the study drug if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.

This is an investigational study. Pegasys is FDA approved and commercially available for the treatment of CML. TKIs (imatinib, nilotinib, and dasatinib) are FDA approved and commercially available for the treatment of CML. The combination of these drugs to treat CML is investigational.

Up to 50 patients will take part in this study. All will be enrolled at MD Anderson.

Actual Enrollment : 2 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Study of Pegylated Ifná-2a (Pegasys) in Patients With Chronic Myeloid Leukemia Who Have Minimal Residual Disease While Receiving Therapy With Tyrosine Kinase Inhibitors
Study Start Date : October 2011
Actual Primary Completion Date : March 2014
Actual Study Completion Date : March 2014

Arm Intervention/treatment
Experimental: PEG-IFNá-2a
PEG-IFNá-2a (Pegasys) 45 mcg subcutaneously as single weekly dose.
Drug: PEG-IFNá-2a
45 mcg given subcutaneously as a single weekly dose for 24 months.
Other Names:
  • Pegasys
  • Peginterferon Alpha-2a

Primary Outcome Measures :
  1. Number of Participants Achieved of Major Molecular Response (MMR) or Complete Molecular Response (CMR) [ Time Frame: 12 months from start of treatment with PEG-IFNá-2a ]
    Molecular response defined as: major molecular response (MMR) corresponds to a BCR-ABL1/ABL1 ratio of <=0.01. Complete molecular response (CMR) is defined as undetectable BCR-ABL1 transcripts. Molecular response measured every 3 months (a total of 4 assessments within one year of therapy).
