About this trial

This phase II trial studies the side effects and how well cladribine and rituximab work in treating patients with hairy cell leukemia. Drugs used in chemotherapy, such as cladribine, work in different ways to stop the growth of cancer cells either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as rituximab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cladribine together with rituximab may kill more cancer cells.

Trial outcomes

Primary outcomes

1

Efficacy of rituximab on achievement of complete response after therapy with cladribine

Defined as the absence of hairy cells in the bone marrow or the presence of less than 1 percent atypical cells and the disappearance of all evidence of hairy cell leukemia on physical examination. Monitored using the method of Thall, Simon, Estey as extended by Thall and Sung.

Time frame
At 12 weeks
2

Monitoring the related toxicity for the therapy Grade 3-4

Monitored using the method of Thall, Simon, Estey as extended by Thall and Sung.

Time frame
Up to 1 year
3

Efficacy of rituximab in eradication of minimal residual disease after cladribine therapy, assessed by immunophenotyping of bone marrow and peripheral blood

The method of Thall, Simon, Estey as extended by Thall and Sung will be used for efficacy and safety monitoring.

Time frame
Up to 4 weeks after the last dose of rituximab
4

Efficacy of rituximab on prolongation of event-free survival

Time frame
Up to 1 year
