About this study

Official title: Phase I Study of Oral Clofarabine for the Treatment of Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia

The goal of this clinical research study is to find the highest tolerable dose of clofarabine when given to patients with CLL. The safety of this drug will also be studied.

Read the detailed description

The Study Drug:

Clofarabine is designed to interfere with the growth and development of cancer cells.

Screening Tests:

Before you can begin taking the study drug, you will have "screening tests" to help the doctor decide if you are eligible to take part in this study. The following tests and procedures will be performed:

  • Your complete medical history will be recorded.
  • You will have a physical exam, including measurement of your vital signs (blood pressure, heart rate, temperature, and breathing rate).
  • You will also be asked about what drugs you are currently taking.
  • You will be asked how well you are able to perform the normal activities of daily living (performance status evaluation).
  • Blood (about 2 tablespoons) will be drawn for routine tests.
  • You will also have a bone marrow aspirate and/or biopsy. To collect a bone marrow aspirate, an area of the hip is numbed with anesthetic and a small amount of bone marrow and bone is withdrawn through a large needle.
  • Women who are able to have children must have a negative blood or urine pregnancy test. The blood would be drawn as part of the routine sample described above.

Study Groups:

If you are found to be eligible to take part in this study, you will be assigned to a dose level of clofarabine based on when you joined this study. Up to 7 dose levels of clofarabine will be tested. Three (3) to 6 participants will be enrolled at each dose level. The first group of participants will receive the lowest dose level. Each new group will receive a higher dose than the group before it, if no intolerable side effects were seen. This will continue until the highest tolerable dose of clofarabine is found.

The dose of clofarabine may be lowered or delayed to help reduce side effects.

Study Drug Administration:

On Days 1-21 of each 28-day study "cycle", you will take clofarabine by mouth once a day (in the morning) at about the same time everyday.

  • You should take clofarabine on an empty stomach.
  • You should try to fast (not eat anything or drink anything other than water) from midnight the night before each dose to 1 hour after taking clofarabine.
  • Clofarabine should be taken with 4 ounces (1/2 a cup) of water.
  • You should not drink coffee and other caffeinated liquids before and for 1 hour after taking the study drug.
  • If you vomit more than 15 minutes after you take the drug, you should not replace or make up the drug. If you vomit less then 15 minutes after taking the drug, you should retake the dose. If you vomit again within 15 minutes after retaking the dose, you should not take the drug again that day and make a note of it in the diary.

Study Visits:

  • On Day 1 of every cycle, the following tests and procedures will be performed:
  • You will have a physical exam, including measurement of your weight and vital signs.
  • You will have a performance status evaluation.
  • You will be asked if you have experienced any intolerable side effects and how you are feeling.

Once a week of Cycle 1, you will have a physical exam.

Once a week of every cycle, blood (about 1-2 teaspoons) will be drawn for routine tests (blood counts with platelets). Your blood will be drawn more often if the doctor feels it is necessary.

After Cycles 3 and 6, you will have a bone marrow aspiration and/or biopsy to check the status of the disease.

If you go off study before Cycle 3 and the doctor thinks it is necessary, the bone marrow aspiration and/or biopsy may be taken when you go off study.

If you have completed all 6 cycles of the study drug, every 6 months (+/- 2 months), you will have a physical exam and blood (about 1-2 teaspoons) will be drawn to check on the status of the disease and your overall health. The study doctor will tell you any other tests that may be needed.

Length of Study You will be on the study drug for up to 6 cycles (about 6 months). You will be taken off study early if the disease gets worse or you experience any intolerable side effects.

Additional Information:

You will need to stay in Houston for Cycle 1 (28 days). After that, you may return to your home but you will still have to return to Houston before each cycle unless you choose to have check-up visits and blood tests with your local doctor.

This is an investigational study. Clofarabine is FDA approved and commercially available when given by vein to pediatric patients for the treatment of acute lymphoblastic leukemia (ALL) that has come back or not responded to other treatments. The use of clofarabine by mouth is not FDA approved. At this time, oral clofarabine is only being used in research.

Up to 36 patients will take part in this study. All will be enrolled at M. D. Anderson.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Oral Clofarabine in people with Leukemia and Chronic Lymphocytic Leukemia, run by M.D. Anderson Cancer Center 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 5 inclusion and 7 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: withdrawn, as of the sponsor's last update on 1 Aug 2012. 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 was withdrawn before enrolling participants, so there are no results.

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?

Maximum tolerated dose (MTD) and Dose limiting toxicities (DLT) (time frame: October 2009). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Aug 2012.
