Epratuzumab and Combination Chemotherapy in Treating Young Patients With Relapsed Acute Lymphoblastic Leukemia
This phase II trial is studying how well giving epratuzumab together with combination chemotherapy works in treating young patients with relapsed acute lymphoblastic leukemia. Monoclonal antibodies, such as epratuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing them or by stopping them from dividing. Giving monoclonal antibody therapy together with combination chemotherapy may kill more cancer cells.

|Official Title:||A Feasibility Pilot and Phase 2 Study Of Chemoimmunotherapy With Epratuzumab (IND #12034) for Children With Relapsed CD22-Positive Acute Lymphoblastic Leukemia (ALL)|
- Feasibility of an intensive chemoimmunotherapy approach for the treatment of relapsed CD-22 positive B-precursor acute lymphoblastic leukemia [ Time Frame: 14 days ] [ Designated as safety issue: No ]
- Toxicity graded using the NCI CTCAE version 4.0 [ Time Frame: Up to 30 days after completion of study treatment ] [ Designated as safety issue: Yes ]
- Response rate determined by bone marrow aspiration and peripheral blood blast counts [ Time Frame: Up to day 36 ] [ Designated as safety issue: No ]Quantified by the observed response rate and associated 95% confidence interval.
- Event-free survival [ Time Frame: 4 months ] [ Designated as safety issue: No ]Estimated using the Kaplan-Meier method.
- Minimal residual disease [ Time Frame: Up to day 36 ] [ Designated as safety issue: No ]Tested using a one-sample Z-test.
- Pharmacokinetics [ Time Frame: Up to day 36 ] [ Designated as safety issue: No ]Determined along with the mean, median, standard deviation and range of the parameters of interest. Statistical analysis will be purely descriptive.
