Primary Outcome Measures:
  • Efficacy as defined by clinical benefit rate [ Time Frame: Up to 24 Months ] [ Designated as safety issue: No ]
    Participants will be followed until progression of disease or start of another anti-cancer treatment.


Secondary Outcome Measures:
  • To evaluate the efficacy of PCI-32765 by assessing the safety profile [ Time Frame: For 30 days after the last dose of PCI-32765 ] [ Designated as safety issue: Yes ]
    To measure the number of patients with adverse events as a measure of safety and tolerability

  • To evaluate the efficacy of PCI-32765 by assessing the drug pharmacokinetics [ Time Frame: Procedure will be performed during the first month of receiving study drug ] [ Designated as safety issue: Yes ]
    To measure the way the body absorbs, distributes and gets rid of the study drug

  • Duration of Clinical Benefit Response (DCB) [ Time Frame: Up to 24 months ] [ Designated as safety issue: No ]
    DCB is defined as the time from first observation of response to the time of disease progression.

Detailed Description:

Bruton's tyrosine kinase (Btk) is an enzyme that is present in hematopoietic cells other than T cells and is necessary for downstream signal transduction from various hematopoietic receptors including the B cell receptor as well as some Fc, chemokine, and adhesion receptors, and is crucial for both B cell development and osteoclastogenesis. Although down-regulated in normal plasma cells, Btk is highly expressed in the malignant cells from many myeloma patients and some cell lines. PCI 32765 is a potent and specific inhibitor of Btk currently in Phase 2 clinical trials. The current study is designed and intended to determine the effects of PCI-32765 in subjects with MM.

Optional Sub-Study:

Subjects entering the main study will be eligible to participate in an exploratory sub-study to investigate possible mechanisms of treatment sensitivity and resistance. Bone marrow specimens will be collected at three timepoints.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Diagnosis of symptomatic MM with measurable disease, defined here as having at least one of the following:

    1. Serum monoclonal protein (M-protein) ≥0.5 g/dL as determined by serum protein electrophoresis (SPEP)
    2. Urine M-protein ≥200 mg/24 hrs
    3. Serum free light chain (FLC) assay: involved FLC level ≥10 mg/dL (≥100 mg/L) provided serum FLC ratio is abnormal
  • Relapsed or relapsed and refractory MM after receiving at least 2 previous lines of therapy, 1 of which must be an immunomodulator.
  • Refractory myeloma (to most recent treatment) is defined as disease that is nonresponsive while on treatment or progressive disease within 60 days after the completion of preceding treatment. Nonresponsive disease is defined as either failure to achieve minimal response or development of progressive disease while on therapy.
  • Men and women ≥18 years of age.
  • ECOG performance status of ≤ 1.

Exclusion Criteria:

  • Subject must not have primary refractory disease defined as disease that is nonresponsive in subjects who have never achieved a minor response (MR) or better with any therapy.
  • Polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes (POEMS) syndrome, osteosclerotic myeloma, or Crow-Fukase syndrome.
  • Plasma cell leukemia.
  • Primary amyloidosis.
  • Certain exclusions on prior therapy.
  • ANC <0.75 x 10^9/L independent of growth factor support.
  • Platelets <50 x 10^9/L) independent of transfusion support.
  • AST or ALT ≥3.0 x upper limit of normal (ULN).
  • Total bilirubin >2.5 x ULN, unless due to Gilbert's syndrome.
  • Creatinine >2.5 mg/dL.
  • Unable to swallow capsules or disease significantly affecting gastrointestinal function.
  • Requires anti-coagulation with warfarin or a vitamin K antagonist. Requires treatment with strong CYP3A4/5 inhibitors.
