| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| The primary objective is to compare maintenance therapy with enzastaurin versus  placebo, in terms of the overall disease-free survival  DFS  time in patients with DLBCL  in first remission with high risk of relapse  initial IPI score    3  following R-CHOP using  a 14- or 21-day cycle. | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
| The secondary objectives of the study are    to compare the following time-to-event efficacy variables between  treatment arms    rate of DFS at 2 years  DFS2    event-free survival  EFS    rate of EFS at 2 years  EFS2    OS time   to compare adverse events between treatment arms   to compare health-related quality of life using the FACT-Lym  Cella et al. 2005    to assess health status using the EQ-5D scale  EuroQol Group 1990    to assess biomarkers relevant to enzastaurin and disease state and their  correlation to clinical outcome   to characterize the pharmacokinetics  PK  of enzastaurin and its  metabolites using a sparse sampling strategy. |

| E.3 | Principal inclusion criteria  | 
| Patients may be included in the study only if they meet all of the following criteria    1  have had a histologically confirmed diagnosis of DLBCL by the World  Health Organization classification  Harris et al. 1999  at the time of  original diagnosis. Pathology must be reviewed and confirmed prior  to enrollment at the investigational site where the patient is entered.  Patients may be entered and randomized based on local pathology;  however, an independent centralized pathology review will be  performed on all enrolled patients  see Section 6.4.1 . Patients with a  prior history of an indolent lymphoma or a histological diagnosis of  follicular Grade 3 lymphoma will not be eligible for enrollment.   2  if any gallium scan was performed, the most recent gallium scan must  be negative. However, gallium scans are not a required study  procedure.   3  if any PET scan was performed, the most recent PET scan must be  negative. However, PET scans are not a required study procedure.   4  have completed six or eight 21-day cycles of R-CHOP, or six 14-day  cycles of R-CHOP as first-line therapy for DLBCL.  Refer to Section  5.5 for recommended regimens.  The patient must have achieved a  CR or CRu  and have not subsequently progressed  according to  International Workshop criteria  Cheson et al. 1999 .   5  have an IPI score    3 at time of original diagnosis  refer to Protocol  Attachment JCBJ.4 .   6  have had Stage 3 or 4 disease, or have had Stage 2 with bulky disease   defined as  10 cm , at time of original diagnosis.   7  have given informed consent.   8  have an estimated life expectancy of at least 12 weeks.   9  have a performance status of 0, 1, or 2 on the Eastern Cooperative  Oncology Group  ECOG  scale  see Protocol Attachment JCBJ.7;  Oken et al. 1982 .   10  exhibit patient compliance and geographic proximity that allow for  adequate follow-up.   11  have adequate organ function as follows     Hepatic  total bilirubin   1.5 times upper limit of normal  ULN ;  alanine transaminase  ALT  and aspartate transaminase  AST     2.5 times ULN    Renal  serum creatinine  1.5 times ULN    Adequate bone marrow reserve  platelets    50 x 109/L, absolute  neutrophil count  ANC    1.0 x 109/L, hemoglobin   8 g/dL.   12  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  within 7 days prior to study enrollment.   13  are at least 18 years of age.   14  Patient must receive on-study therapy no later than 42 days from their  last cycle  Day 1  of induction therapy. | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
| Patients will be excluded from the study if they meet any of the following criteria    1  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.   2  receive concurrent administration of any other systemic anticancer  therapy.   3  have received radiation therapy to more than one targeted lesion  local  residual disease  for treatment of lymphoma.   4  are pregnant or breastfeeding.   5  have central nervous system  CNS  metastases  unless the patient has  completed successful local therapy for CNS metastases and has been  off of corticosteroids for at least 4 weeks before starting study  therapy . In the absence of a clinical suspicion of brain metastases, no  screening computed tomography  CT  or magnetic resonance imaging   MRI  scan before enrollment is required.   6  have serious concomitant disorder, including active bacterial, fungal,  or viral infection, incompatible with the study  at the discretion of the  investigator .   7  have human immunodeficiency virus  HIV  associated lymphomas.   8  have a second primary malignancy  except adequately treated basal  cell carcinoma of the skin . Patients who had another malignancy in  the past, but have been disease-free for more than 5 years, are eligible.   9  have a serious cardiac condition, such as myocardial infarction within  6 months, angina, or heart disease, as defined by the New York Heart  Association Class III or IV  see Protocol Attachment JCBJ.5 .   10  are unable to swallow tablets. |
