Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0, 1, or 2. The following laboratory values obtained prior to registration: Absolute neutrophil count (ANC) greater than or equal to 1000/microliter 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) Aspartate transaminase (AST) less than or equal to 3 x ULN Creatinine less than or equal to 1.5 x ULN Hemoglobin (Hgb) greater than or equal to 8.0 g/dL. Expected survival of greater than 12 weeks. The ability to provide informed consent. Male and female patients with reproductive potential must use an approved contraceptive method, if appropriate (for example, intrauterine device [IUD], birth control pills, or barrier device) during and for 3 months after discontinuation of study treatment. Women with childbearing potential must have a negative serum pregnancy test less than or equal to 3 days prior to study enrollment Exclusion Criteria: Prior allogeneic hematopoietic stem cell transplant. Are unable to discontinue use of non-Enzyme-Inducing Anti-Epileptic Drugs (EIAEDs), for example carbamazepine, phenobarbital, and phenytoin. 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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Complete Response (CR), Partial Response (PR) and Minimal Response (MR) or Minor Response (MinR): (Response Rate) | 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.

Secondary Outcome Measures

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. | Time of response to time of measured progressive disease up to 38.37 months | 
| Time to Progressive Disease | 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. | Baseline to measured progressive disease up to 40.51 months | 
| Number of Participants With Adverse Events (Safety and Adverse Events) | 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.
