PCI-32765 (Ibrutinib) in Treating Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, or B-cell Prolymphocytic Leukemia

We will summarize our findings for this endpoint independently as well within each cohort (del17p vs other cytogenetic groups). We will evaluate the proportion of patients who are progression-free and alive at two years or have gone on to transplant (treatment successes) over the total number of evaluable patients; eligible patients who received at least one dose of therapy are considered evaluable. Assuming that the number of treatment successes as defined above is binomially distributed, we will also include 95% binomial confidence intervals for the estimates corresponding to each cohort.

Responders were subjects who achieved a complete response (CR), partial response (PR) or PR with persistent lymphocytosis. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

The 6 month overall response rates overall response rate (ORR). Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR

Time from date of first treatment with ibrutinib until the date of death from any cause or the date of last contact for those alive.

Time from date of first treatment with ibrutinib until the date of progression or death from any cause. Those alive and progression free are censored at the date of last clinical assessment.

Adverse events grade 3 or higher using the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 with the attribution of either definite, possible or probable related.

Percentage of patients with BTK C481S mutation or PLCG2 mutation

The number of participants with successful Allogenic Stem Cell Transplant

Cancer-Specific Stress was measured by the Impact of Event Scale-Revised Participants rated the intensity of these feelings using a five-point Likert scale ranging from 0=not at all to 4=extremely. Patients rated the frequency of their feelings or events for the previous week before treatment. The items were summed for a total score that ranged from 0 to 64

The Beck Depression Inventory-2nd edition is a 21-item measure of depressive symptoms. Scores were calculated representing the cognitive-affective and the somatic symptoms associated with depression (e.g. sadness, pessimism, loss of pleasure) during past month on scale from 0 to 3. Items were summed, with higher scores indicating more depressive symptoms. The scores on the scale from range from 0 to 42.

The Profile of Mood States-Short Form (POMS-SF) yields six subscales, Tension, Depression, Anger, Vigor, Fatigue, and Confusion. A total mood disturbance score is found by summing the six subscales. Total Mood Disturbance (TMD) scores range from -24 to 124 with higher scores indicating greater mood disturbance.

SF-12 assesses aspects of quality of life including physical functioning, role functioning-physical, bodily pain, general health perceptions, vitality, social functioning, role functioning-emotional, and mental health. Subscale raw scores are transformed to put each subscale on a 0-100 range with higher scores indicative of greater functioning. Subscale scores are standardized based on US General Population norms and aggregated based on factor score coefficients into two component scores: the Physical Component Summary (PCS) and the Mental Component Summary (MCS). Component scores are norm-based t-scores meaning scores above 50 indicate better functioning than average functioning while scores below 50 indicate worse functioning.

The Fatigue Interference quality of life measures is a 11-item self reported questionnaire used to measure frequency, severity and daily pattern of fatigue Symptoms as well as impact of QOL in the past week. The Total Disruption Index (TDI) an 7 item subset of FSI was used. Items were rated on a 11-point Likert scale from 0=no interference to 10=extreme interference. Total scores could range from 0 to 70, with higher scores indicating greater fatigue interference.

Sleep problems quality of life measures is a six-item sleep problems index I of the Medical Outcomes Study-Sleep Scale used to assess sleep problems. Participants reported how often they experience six specific difficulties with sleep on a 6-point Likert scale (1=All of the time to 6=None of the time). Scores transformed into a 0-100 scale with higher scores indicating greater sleep problems.

Physical Health Quality of life measures were administered during screening and on Days 1 (±3), of Cycle 1, Day 1 (±3), of Cycle 2 and on day 1 (±7) of Cycles 3, 6, and then every 3 months thru Cycle 24 and at time of progression and /or end of treatment. SF-12 assesses aspects of quality of life including physical functioning, role functioning-physical, bodily pain, general health perceptions, vitality, social functioning, role functioning-emotional, and mental health. Subscale raw scores are transformed to put each subscale on a 0-100 range with higher scores indicative of greater functioning. Subscale scores are standardized based on US General Population norms and aggregated based on factor score coefficients into two component scores: the Physical Component Summary (PCS) and the Mental Component Summary (MCS). Component scores are norm-based t-scores meaning scores above 50 indicate better functioning than average functioning while scores below 50 indicate worse functioning.
