Stable disease (SD): criteria for CR, VGPR, PR or PD not met.
  • Time to Tumor Progression (TTP): Phase 2 [ Time Frame: Cycle 1 Day 1 (baseline) up to 28 days after last dose of palbociclib ]
    TTP was defined as the time from first dose of study medication to first documentation of objective tumor progression. TTP was calculated as (first event date minus the date of first dose of study medication plus 1) divided by 30.44. Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease [PD] per IMWGURC). PD: >=25% increase from lowest response level in serum M-component or urine M-component, >=10% bone marrow plasma cell percentage, definite development of new bone lesions/soft tissue plasmacytomas/definite increase in size of existing bone lesions/soft tissue plasmacytomas, development of hypercalcemia, attributed solely to plasma cell proliferative disorder.
  • Progression-free Survival (PFS): Phase 2 [ Time Frame: Cycle 1 Day 1 (baseline) up to 28 days after last dose of palbociclib ]
    PFS was the time from start of study treatment to date progressive disease was documented or death due to any cause, whichever occurred first. PFS was calculated as (first event date minus the date of first dose of study medication plus 1) divided by 30.44. Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease [PD]), or from adverse event (AE) data (where the outcome was "Death"). PD: >=25% increase from lowest response level in serum M-component or urine M-component, >=10% bone marrow plasma cell percentage, definite development of new bone lesions/soft tissue plasmacytomas/definite increase in size of existing bone lesions/soft tissue plasmacytomas, development of hypercalcemia, attributed solely to plasma cell proliferative disorder.
  • Duration of Objective Response (DR): Phase 2 [ Time Frame: Cycle 1 Day 1 (baseline) up to 28 days after last dose of palbociclib ]
    DR was defined as time from first documentation of objective tumor response (sCR, CR, VGPR or PR) that was subsequently confirmed to first documentation of objective tumor progression or death due to any cause since treatment started. sCR: normal FLC ratio, absence of clonal cells in bone marrow. CR: disappearance of any soft tissue plasmacytomas, <5% plasma cells in bone marrow, negative immunofixation on serum, urine. VGPR: serum, urine M-protein detectable by immunofixation but not on electrophoresis, >=90% reduction in serum M-protein, <100 mg/24hr urine M-protein. PR:>=50% reduction in serum M-protein, reduction in 24-hr urinary M-protein by >=90% or to <200 mg/24 hr. PD: >=25% increase from lowest response level in serum M-component, urine M-component, >=10% bone marrow plasma cell percentage, development of new bone lesions/soft tissue plasmacytomas/increase in size of existing bone lesions, development of hypercalcemia, attributed solely to plasma cell proliferative disorder.
  • Overall Survival (OS): Phase 2 [ Time Frame: Cycle 1 Day 1 (baseline) up to end of study (up to Cycle 22 for schedule B), thereafter every 3 months until 1 year after the last dose of palbociclib ]
    OS was defined as the time from first dose of study medication to first documentation of death due to any cause. OS was calculated as (the death date or last known alive date [if death date unavailable] minus the date of first dose of study medication plus 1) divided by 30.44.
  • Number of Participants With Adverse Events (AEs) by Severity: Phase 2 [ Time Frame: Cycle 1 Day 1 (baseline) up to 28 days after last dose of palbociclib ]
    An AE was any untoward medical occurrence attributed to study medication in a participant who received study medication. A serious AE (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Adverse events were graded according to the common terminology criteria for adverse events (CTCAE) criteria as 1=mild AE, 2=moderate AE, 3=severe AE, 4=life-threatening or disabling AE, 5=Death related to AE. The most severe grade was used in case of multiple occurrences of the same event.
  • Number of Participants With Treatment-Emergent Adverse Events (TEAEs) by Relationship to Study Medication: Phase 2 [ Time Frame: Cycle 1 Day 1 (baseline) up to 28 days after last dose of palbociclib ]
    An AE was any untoward medical occurrence attributed to study medication in a participant who received study medication. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study medication until 28 days after the last dose of study medication that were absent before treatment or that worsened relative to pretreatment state. All causality AEs included SAEs as well as non-serious AEs, without regard to relationship to the study medication, which occurred during the trial. Treatment-related were adverse events (serious as well as non-serious adverse events) considered related to study medication by the investigator. Number of participants with treatment related TEAEs and all causality TEAEs were summarized.
  • Number of Participants With Laboratory Abnormalities: Phase 2 [ Time Frame: Cycle 1 Day 1 (baseline) up to 28 days after last dose of palbociclib ]
    Laboratory parameters included hematology (hemoglobin, platelets, leukocytes, total neutrophils, eosinophils, basophils, lymphocytes, monocytes); liver function (total bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, albumin, total protein); renal function (creatinine, blood urea nitrogen, uric acid); electrolytes (sodium, potassium, chloride, bicarbonate, calcium, magnesium and phosphate); urinalysis (protein and immunology [C reactive protein]), and clinical chemistry (glucose). Total number of participants with laboratory abnormalities was reported.
  • European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (EORTC QLQ-C30): Phase 2 [ Time Frame: C1D1 (baseline), C1D8, C1D15, C2D1, C3D1, C4D1, C5D1, C6D1, C7D1, C8D1, C9D1, C10D1, C11D1, C12D1, C13D1, C14D1, C15D1, C16D1, C17D1, C18D1, C19D1, C20D1, C21D1, C22D1, End of Treatment (assessment at early withdrawal occurring up to Cycle 22) ]
    EORTC QLQ-C30: included functional scales (physical, role, cognitive, emotional, and social), global health status, symptom scales (fatigue, pain, nausea/vomiting) and single items (dyspnea, appetite loss, insomnia, constipation, diarrhea and financial difficulties). Most questions used 4 point scale (1 'Not at all' to 4 'Very much'); 2 questions used 7-point scale (1 'very poor' to 7 'Excellent'). Scores for functional scales, global health status and symptom scales were calculated as an average of individual items, transformed to 0-100 scale; higher score=better level of functioning, health status or greater degree of symptoms. Score of the single items were transformed to 0-100 scale; higher score=greater degree of symptom/difficulty.
  • Quality of Life Questionnaire Multiple Myeloma Module (QLQ-MY20): Phase 2 [ Time Frame: C1D1 (baseline), C1D8, C1D15, C2D1, C3D1, C4D1, C5D1, C6D1, C7D1, C8D1, C9D1, C10D1, C11D1, C12D1, C13D1, C14D1, C15D1, C16D1, C17D1, C18D1, C19D1, C20D1, C21D1, C22D1, End of Treatment (assessment at early withdrawal occurring up to Cycle 22) ]
    The QLQ-MY20 consisted of 20 items addressing 4 domains of health-related quality of life (HRQoL) important to participants with multiple myeloma: future perspective (2 items), pain/disease symptoms (6 items), social support /body image (2 items), and treatment side-effects (10 items). All items used 4 point scale (1 'Not at all' to 4 'Very much'). Scores for HRQoL domains were calculated as an average of the individual items, transformed to 0 to 100 range. Higher scores on symptom scales (disease symptoms and side effects of treatment) indicated a higher level of symptoms/problems. Higher scores on functional scales (future perspective and body image) indicated a higher level of QoL/functioning.
  • Modified Version of Brief Pain Inventory - Short Form (m-BPI-sf) Questionnaire: Phase 2 [ Time Frame: C1D1 (baseline), C1D8, C1D15, C2D1, C3D1, C4D1, C5D1, C6D1, C7D1, C8D1, C9D1, C10D1, C11D1, C12D1, C13D1, C14D1, C15D1, C16D1, C17D1, C18D1, C19D1, C20D1, C21D1, C22D1, End of Treatment (assessment at early withdrawal occurring up to Cycle 22) ]
    m-BPI-sf was a questionnaire designed to assess the severity of pain and the impact of pain on daily functions. m-BPI-sf contained questions that assessed pain severity (worst, least, average, right now) and pain interference (general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life). Each question was answered on a scale ranging from 0 "No pain" to 10 "Pain as bad as you can imagine". The 4 pain severity questions were averaged to derive an index of pain severity and the 7 function questions were averaged to derive an index for pain interference. Total score range for pain severity and interference indices: 0 to 10, where higher score indicated higher severity/interference.
