|---|---|---|---|
| Primary | Number of Participants Receiving Pentostatin + Rituximab and Bendamustine + Rituximab Who Achieve a Complete Remission (CR) + Partial Response (PR) | At end of treatment, approximately 6 months | Number of participants receiving pentostatin + rituximab and bendamustine + rituximab who achieve a CR +PR measured by the following response criteria. Complete remission is all of the following for at least 4 weeks: absolute neutrophil count ≥ 1500/mm\^3, platelets ≥ 100,000/mm\^3, hemoglobin ≥ 11g/dl, spleen non-palpable below the costal margin, or not below costal margin on computed tomography, and circulating hairy cell leukemia (HCL) cells either non-visible on Wright stain or \< 1% by flow cytometry. Partial response is all of the following for at least 4 weeks: neutrophils ≥ 1,500/µL or 50% improvement over baseline, platelets ≥100,000/µL or 50% improvement over baseline, hemoglobin ≥ 11.0 g/dL or 50% improvement over baseline, ≥ 50% decrease in circulating malignant HCL count from the pretreatment baseline, ≥ 50% reduction in sum of products of perpendicular diameters or decrease to ≤ 2 cm in evaluable (\> 2cm) lymphadenopathy. |
| Secondary | Pentostatin + Rituximab and Bendamustine + Rituximab in Crossover When Used After Failure of the 1st Regimen | 4 years | Compare the 2 regimens - pentostatin + rituximab and bendamustine + rituximab in crossover when used after failure of the 1st regimen. |
| Secondary | Response Rate | 4 years | Response rate between participants who received rituximab plus either pentostatin or bendamustine measured by the following response criteria. Complete remission is all of the following for at least 4 weeks: absolute neutrophil count ≥ 1500/mm\^3, platelets ≥ 100,000/mm\^3, hemoglobin ≥ 11g/dl, spleen non-palpable below the costal margin, or not below costal margin on computed tomography, and circulating hairy cell leukemia (HCL) cells either non-visible on Wright stain or \< 1% by flow cytometry. Partial response is all of the following for at least 4 weeks: neutrophils ≥ 1,500/µL or 50% improvement over baseline, platelets ≥100,000/µL or 50% improvement over baseline, hemoglobin ≥ 11.0 g/dL or 50% improvement over baseline, ≥ 50% decrease in circulating malignant HCL count from the pretreatment baseline, ≥ 50% reduction in sum of products of perpendicular diameters. Progressive disease is appearance of new evaluable lymph nodes \>2cm. Stable disease is none of the above |
| Secondary | Mechanism of Thrombocytopenia | 4 years | The mechanism of thrombocytopenia after purine analog plus rituximab. |
| Secondary | Hairy Cell Leukemia (HCL) Biology | 4 years | HCL biology was determined by cloning, sequencing and characterizing monoclonal immunoglobulin rearrangements, and other genes. |
| Secondary | Correlation of Measurable Residual Disease (MRD) Levels and Tumor Markers With Response | 4 years | Determine if MRD levels and tumor markers (soluble cluster of Differentiation 25 (CD25) and cluster of differentiation-22 (CD22), and real-time quantitative reverse transcriptase polymerase chain reaction (RQ-PCR) correlate with response and clinical endpoints, and if bone marrow magnetic resonance imaging (MRI) signal correlates with bone marrow biopsy (BMBx) results, and whether these tests could in some cases possibly replace BMBx. |
| Secondary | Measurable Residual Disease (MRD)-Free Survival | 4 years | MRD-free survival is defined by the Response criteria. |
| Secondary | Disease-free Survival (DFS) | time from start of treatment to documented evidence of disease progression | Disease-free survival is the time from start of treatment to documented evidence of disease progression measured by the following response criteria. Progressive disease ≥50% increase in sum of products of perpendicular diameters of evaluable (\> 2cm) lymphadenopathy or appearance of new evaluable lymph nodes \>2cm. |
| Secondary | Overall Survival | time between the first day of treatment to the day of death | OS is the time between the first day of treatment to the day of death. |
| Secondary | Grade 3 and/or 4 Toxicity | 4 years | Toxicity was assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. |
| Secondary | Cluster of Differentiation 4 (CD4+) T-cells | 4 years | Cluster of differentiation 4 (CD4+) T-cells assessed by analysis. |
| Other | Number of Participants With Serious and/or Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0) | Date treatment consent signed to date off study, approximately 103 months and 19 days; 133 months and 11 days; 111 months and 15 days; 102 months and 25 days; 44 months and 14 days; and 19 months and 2 days for each group respectively. | Here is the number of participants with serious and/or non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. |
