Acute Lymphocytic Leukemia - Treatment to Achieve Remission

Chemotherapy Drugs Used After Relapse

Many different drugs are used to treat ALL relapses. These drugs include vincristine, asparaginase, anthracyclines (doxorubicin, daunorubicin), cyclophosphamide, cytarabine (ara-C), and epipodophyllotoxins (etoposide, teniposide). Corticosteroids, such as prednisone or dexamethasone, may also be used.

Newer drugs approved for relapsed or refractory ALL are clofarabine (Clolar) and nelarabine (Arranon). Imatinib (Gleevec), a biologic drug, is approved for treating patients with Philadelphia chromosome-positive ALL that has not responded to or has returned after treatment, and dasatinib (Sprycel) is approved for patients who are not helped by imatinib.




Investigational Drugs

Tyrosine kinase inhibitors. Tyrosine kinase is a growth-stimulating protein. Tyrosine kinase inhibitor drugs block the cell signals that trigger cancer growth. Several tyrosine kinase inhibitors, including imatinib (Gleevec) and dastinib (Sprycel), have recently been approved for treating Philadelphia chromosome-positive ALL. However, because patients can develop resistance to these drugs, new tyrosine kinase inhibitors are being investigated. For example, nilotinib (AMN-107) is being studied for patients with Philadelphia chromosome positive ALL who are resistant to imatinib.
