A Study of Participants With Lymphoma Who Take R-CHOP and Enzastaurin Compared to Participants Who Take R-CHOP Only

Percentage of Participants With a PET-Negative Scan (PET-Negative Rate)

The percentage of participants with a PET-negative scan=(Number of participants who had a PET-negative scan at Cycle 6)/(Number of participants who had a PET-positive scan at baseline)\*100.

Time frame: Cycle 6 (21 days/cycle)

Percentage of Participants With Complete Response (CR/CRu) and/or Post-Baseline PET-Negative Scan (Concordance Between Response and PET Scan)

Lesion response was assessed according to International Working Group recommendations (Cheson et al. 1999). CR is a complete disappearance of all disease with the exception of nodes. No new lesions. Previously enlarged organs must have regressed and not be palpable. Bone marrow must be negative if positive at baseline. Normalization of markers. CRu does not qualify for CR above, due to a residual nodal mass or an indeterminate bone marrow. Percentage of participants with CR/CRu and/or PET-negative scan=(Number of participants with complete response and/or PET-negative scan at Cycle 6)/(Number of participants with a PET-positive scan at baseline)\*100.

Time frame: Cycle 6 (21 days/cycle)

Event-Free Survival (EFS)

EFS is the elapsed time from the date of randomization to the first date of objectively-determined PD, institution of a new anticancer treatment (other than maintenance therapy), or death from any cause. PD was assessed according to International Working Group recommendations (Cheson et al. 1999). PD: Enlarging liver/spleen nodules, new or increased lymph nodes/masses and reappearance of bone marrow infiltrate. For participants not known to have died as of the data cut-off date, who did not have objectively determined disease progression, and who were not treated with a new anticancer treatment, EFS was censored at the date of the last objectively determined disease-free assessment.

Time frame: Randomization to measured PD, start of new therapy, or death from any cause (up to 55 months)

Overall Survival (OS)

OS is the elapsed time from the date of study enrollment (baseline) to the date of death from any cause. For participants not known to have died as of the data cutoff date, OS was censored at the last contact date or last date known to be alive, whichever was later.

Time frame: Baseline to death from any cause (up to 55 months)

Duration of Complete Response (CR or CRu)

Duration of response (DOR) either CR or CRu: Elapsed time from date CR or CRu criteria met to first objectively-determined PD. For responding participants (pts) who died without PD and pts not known to have died as of data cut-off date, who did not have PD, DOR censored at date of last objective progression-free disease assessment. For responding pts who received subsequent systemic anticancer therapy (other than enzastaurin maintenance therapy) prior to PD, DOR was censored at date of last objective progression-free disease assessment prior to subsequent therapy. CR and CRu defined using International Working Group recommendations (Cheson et al. 1999). CR is a complete disappearance of all disease with the exception of nodes. No new lesions. Previously enlarged organs must have regressed and not be palpable. Bone marrow (BM) must be negative if positive at baseline. Normalization of markers. CRu does not qualify for CR above, due to a residual nodal mass or an indeterminate BM.

Time frame: Time of response to PD (up to 55 months)

Participants Who Had Treatment-Emergent Adverse Events (TEAEs) or Died (Evaluate Toxicity and Tolerability of R-CHOP Plus Enzastaurin)

Data presented are the number of participants who experienced at least 1 TEAE, Grade 3 or 4 Common Terminology Criteria for Adverse Events (CTCAE), serious adverse event (SAE), as well as the number of participants who discontinued due to an adverse event (AE) or SAE, who died on therapy, died within 30 days post treatment or within 60 days of first dose. A summary of SAEs and other non-serious AEs, regardless of causality, is located in the Reported Adverse Events module.

Time frame: First dose through 30 days post study treatment discontinuation (up to 56 months)

PFS of Participants With High or Low Expression of Protein Biomarkers and Correlation of Biomarkers to PFS

Reported is PFS of participants (pts) with high or low biomarker expression levels. PFS: time from randomization to first date of PD/death from any cause. PD assessed according to International Working Group recommendations (Cheson et al. 1999). PD: Enlarging liver/spleen nodules, new/increased lymph node/masses and reappearance of bone marrow infiltrate. For pts who had subsequent anticancer therapy, PFS censored at date of last assessment prior to subsequent therapy. Biomarkers and number of pts censored: EIF4EBP1 Cytoplasm (C) 4,3,7,3; EIF4EBP1 Nucleus (N) 0,2,11,4; EIF4E C 5,2,6,4; EIF4E N 0,0,11,6; HDAC2 N 5,1,5,5; PCREB N 5,3,6,4; PEIF3746 C 4,2,7,4; PEIF3746 N 5,2,6,4; PEIFS209 C 5,2,5,4; PEIFS65 N 7,2,4,4; PEIFT70 C 5,2,6,4; PEIFT70 N 6,4,5,2; P GSK3B C 7,3,4,3; PKCb2 C 4,3,7,3; PS6 C 9,4,1,1; PTEN C 5,2,6,4; PTEN N 3,0,8,6. Correlation of biomarkers with PFS (statistical analyses) reported if high expression groups combined and low expression groups combined each had ≥10 pts.

Time frame: Randomization to measured PD or death from any cause (up to 55 months)]
