Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Recommended Phase 2 Dose (RP2D) of Tazemetostat as a Single-Agent and in Combination With Prednisolone (Phase 1 Only)
Time Frame: The first 28-day cycle of therapy
|
Recommended Phase 2 dose (RP2D) of tazemetostat as administered orally twice daily (BID), continuously in 28-day cycles in subjects with advanced solid tumors or with relapsed and/or refractory B cell lymphomas as determined by incidence, seriousness, toxicity grade, and relatedness of treatment emergent dose limiting toxicities
|
The first 28-day cycle of therapy
|
Objective Response Rate (ORR; Complete Response + Partial Response [CR + PR]) (Phase 2)
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
|
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.

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

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Duration of Response for Tazemetostat as a Single Agent or in Combination With Prednisolone (Phase 2 Only)
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 PD/death, a maximum of approximately 82 months
|
The time (in months) from the date of the initial response (CR or PR, whichever was first) until the date of the first documented disease progression per an Independent Review Committee (for Groups 1 and 2), per Investigator (Group 3), or death due to any cause.
Patients who were alive and progression free at the time of the analysis were censored at the last date where the patient was known to be in response.
Note: the DOR was censored, meaning data collection was stopped early for analysis, making the top limit of the 95% confidence interval not estimable (NE).
Per RECIST v.1.0,
CR was defined as disappearance of all target and non-target lesions and any pathological lymph nodes must be <10 mm in the short axis.
The 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.

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 PD/death, a maximum of approximately 82 months
|
The time (in months) from the date of first dose of tazemetostat until the earliest date of disease progression or death from any cause.
Per RECIST v1.0, CR was defined as disappearance of all target and non-target lesions and any pathological lymph nodes must be <10 mm in the short axis.
