Brief Summary:
The goal of this clinical research study is to compare the effectiveness of 2 different doses of the drug clofarabine that can be given on a weekly schedule for the treatment of Myelodysplastic Syndrome (MDS). The safety of these two doses will also be compared.
Primary Objective: Compare the response rates of two dose schedules of clofarabine in MDS.
Secondary Objective: Compare response durations, survivals and side effects of the two schedules.
Detailed Description:
Clofarabine is a new chemotherapy drug that is designed to interfere with the growth and development of cancer cells.
If you are found to be eligible to take part in this study, you will be randomly assigned (as in the toss of a coin) to one of two treatment groups (Groups A and B). Participants in Group A will receive a lower dose of clofarabine. Participants in Group B will receive a higher dose of clofarabine. At first, there will be an equal chance of being assigned to either group. However, as experience increases and more information becomes available, the chance of being assigned to the group that has shown the most effectiveness will increase. You and the study doctor will know to which group you are assigned.
Participants will receive clofarabine as a 1-hour infusion into a vein once a day for 5 days in a row. This will be repeated every 4 to 8 weeks. Each 4-8 week period is considered 1 cycle of treatment.
For participants in both groups, after each cycle of therapy, they will not receive the next cycle of chemotherapy until their blood counts have recovered and any possible side effects have gone away (for around 4 to 8 weeks). You must stay in Houston for the first treatment cycle (about 4 to 8 weeks) and will be required to return to Houston before receiving each additional cycle of chemotherapy (up to 6 days each cycle).
Before every treatment cycle, your doctor will perform a physical exam, including measurement of your weight and vital signs (blood pressure, heart rate, temperature, and breathing rate). You will be asked about the level of your daily activities and how you are feeling. You will have blood samples (about 1-2 teaspoons) collected for routine lab tests 1-2 times a week for the first cycle, then every 2-4 weeks while on therapy. Repeat bone marrow samples will be collected every 1-3 cycles. However, if you complete the study before the third cycle, the bone marrow may be taken then. You may choose to have check-up visits and blood tests with your local doctor.
If you show a response and do not experience any severe side effects, you can receive up to a total of 12 cycles of therapy. During each cycle, clofarabine will be given the same way as during the first cycle. However, the dose of clofarabine may be lowered during later cycles to decrease the risk of side effects that may have occurred in previous cycles. If the disease gets worse or you experience any intolerable side effects, you will be taken off the study and your doctor will discuss other treatment options with you.
This is an investigational study. Clofarabine is approved by the FDA for treatment of pediatric acute lymphoblastic leukemia. Its use in this study is experimental. Up to 60 participants will take part in this study. All will be enrolled at M. D. Anderson.
