Registered outcomes3

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryNumber of Patients Who Obtain Partial Response/Complete Remission6 months
Partial response requires all of the following for a period of at least 4 weeks: ≥50% decrease in hairy cell count from pretreatment baseline value by flow cytometry. ≥50% reduction in abnormal hepatosplenomegaly by computed tomography or physical exam. No growth in lymphadenopathy. Neutrophils ≥1,500/µL or 50% improvement over baseline without growth factors for at least 4 weeks. Platelets ≥100,000/µL or 50% improvement over baseline. Complete remission requires all of the following: no evidence of leukemic cells by routine hematoxylin and eosin stains of the peripheral blood and bone marrow. No hepatomegaly, splenomegaly, or lymphadenopathy (not \>2 cm in short axis) by physical examination and appropriate radiographic techniques. Normal complete blood count as exhibited by Neutrophils ≥1,500/µL, Platelets ≥100,000/µL, and Hemoglobin ≥11.0g/dL without transfusions or growth factors for at least 4 weeks.
SecondaryDuration of ResponseParticipants were assessed at 5.0658, 12.0066, 20.1645, 26.9079, 35.0987, and 45.1316 months
Duration of response is the duration that the patients qualifies for at least a Partial Response (PR). Partial response requires all of the following for a period of at least 4 weeks: ≥50% decrease in hairy cell count from pretreatment baseline value by flow cytometry. ≥50% reduction in abnormal hepatosplenomegaly by computed tomography or physical exam. No growth in lymphadenopathy. Neutrophils ≥1,500/µL or 50% improvement over baseline without growth factors for at least 4 weeks. Platelets ≥100,000/µL or 50% improvement over baseline. Hemoglobin ≥11.0 g/dL or 50% improvement over baseline without transfusions or growth factors for at least 4 weeks.
SecondaryNumber of Participants With Serious and Non-serious Adverse Events Assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0)Date treatment consent signed to date off study, approximately 83 months and 15 days.
Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria in 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.
