What was measured

Here is the number of participants with serious and/or non-serious adverse events (AE's) assessed by the Common Terminology Criteria for Adverse Events (CTCAE v3.0). 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.

Groups in this outcome

Cohort 1 Arm 1 SubGroup 1 -Cladribine + Rituximab

Participants with Hairy Cell Leukemia (HCL) with (62 participants) and without (68 participants) prior course of purine analog to be randomized between Arm 1 and Arm 2 (randomization stratified based upon prior purine analog \[yes/no\]). Cladribine + Rituximab.

Cohort 1 Arm 1 SubGroup 2 -Cladribine + Rituximab

Participants with Hairy Cell Leukemia (HCL) with (62 participants) and without (68 participants) prior course of purine analog to be randomized between Arm 1 and Arm 2 (randomization stratified based upon prior purine analog \[yes/no\]). Cladribine + Rituximab.

Cohort 1 Arm 2 SubGroup 1-Cladribine(+Rituximab After 6 Months if Minimal Residual Disease Detected)

Participants with Hairy Cell Leukemia (HCL) with (62 participants) and without (68 participants) prior course of purine analog to be randomized between Arm 1 and Arm 2 (randomization stratified based upon prior purine analog \[yes/no\]). Cladribine (+ Rituximab after 6 months if minimal residual disease (MRD) detected).

Cohort 1 Arm 2 SubGroup 2-Cladribine(+Rituximab After 6 Months if Minimal Residual Disease Detected)

Participants with Hairy Cell Leukemia (HCL) with (62 participants) and without (68 participants) prior course of purine analog to be randomized between Arm 1 and Arm 2 (randomization stratified based upon prior purine analog \[yes/no\]). Cladribine (+ Rituximab after 6 months if minimal residual disease (MRD) detected).

Cohort 2 Arm 3 SubGroup 1-Cladribine (Rituximab Before 1st of 5 Daily Doses of Cladribine on Day 1)

Participants with Hairy Cell Leukemia (HCL) without prior course of purine analog to be directly assigned to Arm 3 (25 participants; after completion of the 68 participants without prior purine analog in Cohort 1). Cladribine + Rituximab (Rituximab will be administered just before rather than after the 1st of the 5 daily doses of cladribine

Cohort 3Arm3 HairyCell LeukemiaVariant-Cladribine +(Rituximab Before 1st of 5 Daily Doses Cladribine

Participants with Hairy Cell Leukemia Variant (HCLv) to be directly assigned to Arm 3 (20 participants). Cladribine + Rituximab (Rituximab will be administered just before rather than after the 1st of the 5 daily doses of cladribine
