 Summary: 
 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. 
 Detailed description: 
 PRIMARY OBJECTIVES:
I. To demonstrate the efficacy in achieving complete response of combination of
cladribine administered intravenously over 2 hours for 5 days followed by rituximab
weekly for 8 weeks in patients with untreated or previously treated hairy cell leukemia.
II. To examine the efficacy of rituximab to eradicate minimal residual disease (MRD)
after cladribine therapy (as assessed by immunophenotyping of bone marrow and peripheral
blood).
III. To examine the effect of addition of rituximab to cladribine on the long term
disease-free (DFS) and overall survival (OS) (as compared with historical controls).
IV. To evaluate potential predictors of outcome including molecular and flow evaluations
of MRD, as well as other potential molecular predictors such as v-raf murine sarcoma
viral oncogene homolog B1 (BRAF).
OUTLINE:
Patients receive cladribine intravenously (IV) over 2 hours once daily (QD) on days 1-5
and rituximab IV once weekly for 8 weeks beginning on day 28 in the absence of disease
progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year.
