All-trans Retinoic Acid, and Arsenic +/- Idarubicin

April 23, 2019 updated by: M.D. Anderson Cancer Center

Treatment of Acute Promyelocytic Leukemia (APL) With All-Trans Retinoic Acid, and Arsenic +/- Idarubicin

The goal of this clinical research study is to learn if the combination of arsenic trioxide (ATO) with ATRA and possibly idarubicin is effective in treating patients with newly-diagnosed APL.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

All-trans retinoic acid (ATRA) and ATO are designed to cause the APL cells to mature and function normally. Idarubicin is designed to cause breaks in both strands of DNA (the genetic material of cells).

If you are found to be eligible to take part in this study, you will begin induction. During induction, you will receive ATRA, by mouth starting on Day 1. You will also receive ATO through a needle in your vein over 2 hours starting on Day 1. You will continue receiving the drugs every day until your bone marrow no longer shows APL cells.

If you had a high white blood cell count at screening, you will receive idarubicin through a needle in your vein over about 30 minutes one dose only on any day of Day 1 through 5.

During induction, blood (about 1-3 tablespoons) will be drawn every day during Week 1, and then 2 times a week after that. This blood will be drawn for routine tests.

During induction (about 21-28 days after beginning treatment), you will have a bone marrow aspirate to check the status of the disease. This may be performed more often if the doctor thinks it is needed.

If you achieve a complete remission during the induction phase, you will continue to the maintenance phase. During the maintenance phase, you will receive ATO by vein over 2 hours Monday-Friday for 4 weeks. After the 4 weeks of receiving the study drug, you will have a 4-week period "off" (when no study drug is given). ATRA is given by mouth every day for 2 weeks. This 2 weeks is followed by 2 additional weeks when no study drug will be given. You will continue to take ATRA until treatment with ATO is complete.

During maintenance, blood (about 1-3 tablespoons) will be drawn before every 4-week cycle of ATO, and then every week for routine tests. You will also have an ECG before every 4 week cycle when you take ATO.

If you do not achieve a complete remission during induction you will be taken off study.

If at any point during the study your white blood cell count rises above 10,000, you will receive idarubicin by vein over 30 minutes.

You will remain in the hospital for about the first 7 days of induction. After that, you must remain in Houston for the next 3-4 weeks. Once in the maintenance phase, you may be treated at home, but must return to M. D. Anderson for study visits.

After maintenance is complete, you will have follow-up visits for an additional 2 years. If at any time during the active study or follow-up the disease gets worse or intolerable side effects occur, you will be taken off the study.

If you had a low or high white blood cell count when you joined the study, you will have follow-up visits every 3 months for 2 years. At these visits, blood (about 1 tablespoon) will be drawn for routine tests and you will have a bone marrow aspirate.

This is an investigational study. Idarubicin, ATRA and ATO are FDA approved and commercially available. However, their use in this study and in this combination is considered investigational. Its use in APL patients is investigational. Up to 80 patients will take part in this multicenter study. All will be enrolled at M. D. Anderson.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
