Bortezomib With Chemotherapy for Relapsed Pediatric Acute Lymphoblastic Leukemia (ALL)
This is a Phase I/II study of a drug called bortezomib given in combination with chemotherapy drugs used to treat acute lymphoblastic leukemia (ALL) that has come back (recurred). Bortezomib is a drug that has been approved by the Food and Drug Administration (FDA) for treating adults with multiple myeloma which is a type of blood cancer. Bortezomib has been shown to cause cancer cells to die in studies done on animals (mice). Studies have been done that have shown that some adults and children with cancer have shown a response to bortezomib when it is used alone. Studies have also been done in adults to evaluate the dose of bortezomib that can be safely given in combination with other chemotherapy drugs.
The Phase I portion of this study is complete and the dose for the phase II portion of the study is 1.3mg/m2/day. The phase II portion of the study is open and accruing.
Acute Lymphoblastic Leukemia
Drug: bortezomib (Velcade)
|Study Design:||Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Study of Bortezomib With Chemotherapy for Relapsed/Refractory Acute Lymphoblastic Leukemia|
- Dose limiting toxicity [ Time Frame: Each dose level is evaluated ]
- Maximum tolerated dose [ Time Frame: Each dose level is evaluated ]
- Rate of remission [ Time Frame: The rate of remission will be evaluated upon completion of the phase I portion and then the phase II portion. ]
|Study Start Date:||June 2006|
|Primary Completion Date:||February 2011 (Final data collection date for primary outcome measure)|
Drug: bortezomib (Velcade)
All patients will receive 1 course of chemotherapy unless medical complications prevent the administration of some of the drugs. Treatment will last about 1 month.
Treatment on this study will consist of a combination of 7 anti-cancer medications. The 7 anti-cancer medicines are bortezomib, vincristine, dexamethasone, PEG-asparaginase, doxorubicin, cytarabine (Ara-C), and methotrexate (MTX).
If you are in the Phase I portion of this study, you will be given an assigned dose of bortezomib. The dose of bortezomib will be based on doses given in previous studies done with adults and children. At each dose level of bortezomib, between 3 and 6 children will receive bortezomib in combination with chemotherapy. If the side effects are not too severe, the next group of children will receive a higher dose. The dose will continue to be increased until we find the dose that causes serious side effects. Your dose of bortezomib will not be increased. If you have bad side effects, your dose may be decreased.
The dose used during the Phase 2 part of this study will be determined by the outcome of the Phase I study. The highest dose used in Phase I that was tolerated without serious side effects will be the one used in Phase 2.
