  • Platelet (PLT) count greater than or equal to 75,000/microliter
  • Total bilirubin less than or equal to 1.5 x ULN (if total is elevated check direct and, if normal, patient is eligible)

  • Creatinine less than or equal to 1.5 x ULN

Exclusion criteria

  • Prior allogeneic hematopoietic stem cell transplant.

Patients on anti-coagulant therapy should be monitored. Ongoing treatment with therapeutic doses of Coumadin is prohibited. However, prophylactic, low dose (less than or equal to 2 mg daily) Coumadin for deep venous thrombosis (DVT) is allowed. In such cases, prothrombin time/ international normalized ratio (PT/INR) should be closely monitored.
  • Have electrocardiogram (ECG) abnormalities including baseline 12-lead ECG with QTc interval of greater than 450 milliseconds (msec) in males or greater than 470 msec in females, or QRS duration of greater than 100 msec. Patients who have a congenital long-QT-syndrome in their own or family medical history should be excluded at the investigator's discretion.
  • Have an uncontrolled infection.
  • Have prior treatment with Carmustine (BCNU) 6 weeks, alkylating agent 4 weeks, or other cytotoxic chemotherapy agents 4 weeks prior to registration in this trial. Have prior treatment with biologic therapy less than or equal to 12 weeks or corticosteroids less than or equal to 2 weeks prior to registration in this trial. However, treatment with less than or equal to 10 mg of prednisone as a chronic therapy is allowed.
  • Have radiation therapy less than or equal to 2 weeks prior to treatment in this trial.
  • Are pregnant or breast-feeding.
  • Are being treated with concurrent chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy considered investigational.
  • Are known to be human immunodeficiency virus (HIV) positive.
  • Were previously treated with enzastaurin.
  • Patients who are unable to swallow tablets.
  • Have received treatment within the last 30 days with a drug that has not received regulatory approval for any indication at the time of study entry.
  • Concurrent malignancy that could complicate interpretation of response or safety evaluation. Non-melanoma skin cancer and carcinoma in situ of the cervix are not exclusions.

Treatment and study plan

enzastaurin

Drug

Enzastaurin: Cycle 1 Day 1 only: 3, 125-milligrams (mg) tablets three times on Day 1 (Day 1 total dose = 1125 mg)

Primary outcomes

  1. Percentage of Participants With Complete Response (CR), Partial Response (PR) and Minimal Response (MR) or Minor Response (MinR): (Response Rate)

    Time frame: Baseline to measured progressive disease up to 40.51 months

    European Group for Blood and Bone Marrow Transplant (EBMT) Response Criteria (RC) used for MM. CR: no serum/urine M protein for 6 weeks (wk), <5% plasma cells in bone marrow (PCBM), no lytic bone lesions (LBL) size/number increase, no soft tissue plasmacytomas (STPC); PR: met some CR criteria plus maintain for 6 wk ≥50% serum monoclonal paraprotein (SPEP) and PCBM decrease, either decrease of ≥90% or <200 mg light chain excretion (LCE), ≥50% STPC size decrease; MR: met some PR criteria plus maintain for 6 wk, a decrease of: 25-49% SPEP, 50-89% 24 hour urinary LCE, 25-49% PCBM, 25-49% STPC size. International Workshop on WM (IWWM) RC used for WM. CR: no serum M protein, malignant cells in BM, or lymphadenopathy/organomegaly; PR: ≥50% immunoglobulin M (IgM) and adenopathy/organomegaly (A/O) decrease; no new symptoms of WM. MinR: ≥25% to <50% IgM decrease, no A/O progression; no cytopenias or clinical symptoms of WM.

Secondary outcomes

  1. Duration of Response (DOR)

    Time frame: Time of response to time of measured progressive disease up to 38.37 months

    DOR is defined as elapsed time from the first evidence of CR, PR, MR or MinR until date of progression of disease (PD). EBMT RC used for MM. CR: no serum/urine M protein for 6 wk, <5% PCBM, no LBL size/number increase, no STPC; PR: met some CR criteria plus maintain for 6 wk ≥50% SPEP and PCBM decrease, either decrease of ≥90% or <200 mg LCE, ≥50% STPC size decrease; MR: met some PR criteria plus maintain for 6 wk decrease of: 25-49% SPEP, 50-89% 24 hour urinary LCE, 25-49% PCBM, 25-49% STPC size. PD: >25% increase in SPEP, 24 hour urinary LCE, PCBM, STPC size increase, new bone lesion or STPC. IWWM RC used for WM. CR: no serum M protein, malignant cells in BM, or lymphadenopathy/organomegaly; PR: ≥50% IgM and A/O decrease; no new WM symptoms. MinR: ≥25% to <50% IgM decrease, no A/O progression; no cytopenias or clinical of WM symptoms. PD: >25% IgM increase, progression of clinical findings or symptoms. For participants who had no PD, DOR was censored at their last contact.

  2. Time to Progressive Disease

    Time frame: Baseline to measured progressive disease up to 40.51 months

    Time to progression is defined as the elapsed time from the date of study enrollment to the date of objectively determined progressive disease (PD). European Group for Blood and Bone Marrow Transplant (EBMT) Response Criteria was used for MM. PD: >25% increase in serum monoclonal paraprotein (SPEP), 24 hour urinary light chain excretion (LCE), plasma cells in bone marrow (PCBM), soft tissue plasmacytomas (STPC) size increase, new bone lesion or STPC. International Workshop on WM (IWWM) Response Criteria was used for WM. PD: >25% immunoglobulin M (IgM) increase, progression of clinical findings or symptoms. For participants who had no PD, time to PD was censored at their last contact.

  3. Number of Participants With Adverse Events (Safety and Adverse Events)

    Time frame: Treatment start to 30 days after discontinuation of study treatment up to 23.40 months

    Data are presented as number of participants who experienced serious adverse events or all other nonserious adverse events during the study including the 30-day follow-up period. A summary of serious adverse events and other nonserious adverse events is located in the Reported Adverse Event section. Safety data were collected up to 24 cycles plus 30 days of follow-up for a total up to 23.40 months.

Other outcomes
