MeasureTime frameDescription
Percentage of Participants With Relapsed or Refractory DLBCL Who Are Progression-Free for at Least 2 Cycles (28-Day Cycles) After Receiving Enzastaurin (LY317615) (Clinical Response Rate)Randomization to measured progressive disease (PD) up to 34.3 monthsClinical Response Rate in participants with DLBCL was calculated as (number of participants who were progression-free for at least two 28-day cycles \[clinical responder\]) divided by (total number of participants analyzed) multiplied by 100. Progression free survival (PFS) defined as the time from randomization to the first observation of disease progression or death due to any cause. Progression is defined using Response Evaluation Criteria in Solid Tumors Criteria (RECIST v 1.0) as 20% increase in the sum of the of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

PR was defined as a ≥50% decrease in the SPD in the 6 largest dominant nodes or nodal masses, no increase in size in the other nodes, liver or spleen, regression of nodes/lesions in organs by ≥50% in the SPD, and no new disease sites. PD defined as \>50% increase in SPD of the dominant nodal/non-nodal sites or new lesions. For participants who died, the duration of response was censored at death. For participants still alive, duration of overall response was censored at the last visit or follow-up visit. DOR was not analyzed due to low number of responders (CR or PR).

Pre-assignment details

Participant Flow is reporting participants who discontinued from study drug. Per the protocol, a participant completed the study if the planned duration of treatment (6 cycles) was completed in the absence of disease progression or other reasons for discontinuation.

Percentage of Participants With Relapsed or Refractory DLBCL Who Are Progression-Free for at Least 2 Cycles (28-Day Cycles) After Receiving Enzastaurin (LY317615) (Clinical Response Rate)

Clinical Response Rate in participants with DLBCL was calculated as (number of participants who were progression-free for at least two 28-day cycles \[clinical responder\]) divided by (total number of participants analyzed) multiplied by 100. Progression free survival (PFS) defined as the time from randomization to the first observation of disease progression or death due to any cause. Progression is defined using Response Evaluation Criteria in Solid Tumors Criteria (RECIST v 1.0) as 20% increase in the sum of the of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

Time frame: Randomization to measured progressive disease (PD) up to 34.3 months

Population: All randomized participants who remained on study for at least 1 cycle of treatment.

Duration of Overall Response (DOR)

Duration of CR or PR was defined as the time from first objective assessment to first time of disease progression or death from any cause using the modified SWOG Response criteria. CR defined as the disappearance of detectable clinical and radiographic evidence of disease, regression of lymph nodes, nodal masses and spleen to normal size and absence of lymphoma in bone marrow infiltrate. PR was defined as a ≥50% decrease in the SPD in the 6 largest dominant nodes or nodal masses, no increase in size in the other nodes, liver or spleen, regression of nodes/lesions in organs by ≥50% in the SPD, and no new disease sites. PD defined as \>50% increase in SPD of the dominant nodal/non-nodal sites or new lesions. For participants who died, the duration of response was censored at death. For participants still alive, duration of overall response was censored at the last visit or follow-up visit. DOR was not analyzed due to low number of responders (CR or PR).
