Time frame
Radiologic tumor assessments performed at baseline(within 28 days before start of study treatment)and every 8 weeks during Cycles 2 to 6,and then every 12 weeks thereafter until confirmed disease progression (PD)/death,a maximum of approximately 82 months

What was measured

Number of patients achieving an objective response (CR or PR)/number of patients treated x 100%. ORR was calculated as the percentage of patients with a confirmed complete response (CR) or partial response (PR) relative to the total number of patients in the analysis population per response evaluation criteria in solid tumors (RECIST) version (v)1.1. Complete Response (CR) was defined as disappearance of all target and non-target lesions and any pathological lymph nodes must be \<10 millimeter (mm) in the short axis. Partial Response (PR) was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters.

Groups in this outcome

Phase 2 Group 1: Tazemetostat in R/R FL With Mutant EZH2

Patients with R/R FL with mutant EZH2 treated with tazemetostat as a single agent in Phase 2 of the study. Patients received 800 mg of tazemetostat, orally BID, administered in continuous 28-day treatment cycles until confirmed disease progression, unacceptable toxicity, or withdrawal of consent.

Phase 2 Group 2: Tazemetostat in R/R FL With Wild-Type EZH2

Patients with R/R FL with wild-type EZH2 treated with tazemetostat as a single agent in Phase 2 of the study. Patients received 800 mg of tazemetostat, orally BID, administered in continuous 28-day treatment cycles until confirmed disease progression, unacceptable toxicity, or withdrawal of consent.

Phase 2 Group 3: Tazemetostat in R/R DLBCL Monotherapy

Patients with R/R DLBCL received 800 mg of tazemetostat monotherapy, orally BID, administered in continuous 28-day treatment cycles until confirmed disease progression, unacceptable toxicity, or withdrawal of consent.

Phase 2 Group 4: Tazemetostat + Prednisolone in R/R DLBCL Combination Therapy

Patients received tazemetostat 800 mg tablets orally BID in continuous 28-day treatment cycles until confirmed disease progression, unacceptable toxicity, or withdrawal of consent. In addition, these patients also received prednisolone 40 mg/m\^2 on Days 1 to 5 and 15 to 19 from Cycle 1 to Cycle 4 post which tazemetostat monotherapy was continued.
