A Study of Tazemetostat in Adult Participants With Soft Tissue Sarcoma

A Phase II, Multicenter Study of the EZH2 Inhibitor Tazemetostat in Adult Subjects With INI1-Negative Tumors or Relapsed/Refractory Synovial Sarcoma

This study will include participants with various types of cancer known as soft-tissue sarcomas.

Tissues that can be affected by soft tissue sarcomas include fat, muscle, blood vessels, deep skin tissues, tendons and ligaments.

Soft tissue cancers are rare and can occur almost anywhere in the body.

Part 1 of this trial will study the safety and the level that adverse effects of the study drug tazemetostat in combination with doxorubicin (current front line treatment) can be tolerated (known as tolerability).

It is also designed to establish a recommended study drug dosage for the next part of the study.

Part 2 will evaluate and compare how long participants live without their disease getting worse when receiving the study drug plus doxorubicin versus doxorubicin plus placebo (dummy treatment).

Participants will be dosed in continuous 28-day cycles. (Note: if treatment with study drug is discontinued prior to completing 2 years, subjects will be followed for a maximum duration of 2 years from start of study drug dosing.) Response assessment will be performed every 8 weeks while on study.

Treatment with tazemetostat will continue until disease progression, unacceptable toxicity or withdrawal of consent, or termination of the study.

Cohorts 1, 3, 4, 5, 6 and 7: Objective Response Rate (ORR)	ORR was defined as percentage of participants who achieved a confirmed complete response (CR) or partial response (PR) based on the investigator review from start of treatment until progressive disease (PD) or start of subsequent anti-cancer therapy or cancer-related surgery, whichever was earlier, as per response assessment in neuro-oncology (RANO) criteria for primary brain tumors or response evaluation criteria in solid tumors (RECIST) version (v) 1.1 criteria for all other solid tumors. CR was defined as disappearance of all target and non-target lesions. Any pathological lymph nodes must be <10 millimeter (mm) in short axis. PR was defined as at least 30% decrease in sum of diameters of target lesions, taking as a reference, baseline sum of diameters. PD was defined as at least a 20% increase in sum of diameters of target lesions, taking as a reference, smallest sum of diameters recorded since treatment started. In addition, sum must have an absolute increase from nadir of 5 mm.	Tumor assessment performed at screening and every 8 weeks beginning at Cycle 3 Day 1, until disease progression or the start of subsequent anti-cancer therapy, whichever occurred first, up to 5.75 years (cycle duration: 28 days)
Cohort 2: Progression-Free Survival (PFS) Rate at 16 Weeks of Treatment With Tazemetostat	PFS was defined as the interval of time between the date of the first dose of study treatment and the earliest date of PD or death due to any cause, whichever comes first, as per RECIST v 1.1 criteria. PFS rate at 16 week was estimated. PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as a reference, smallest sum of diameters recorded since the treatment started. In addition, the sum must have an absolute increase from nadir of 5 mm.	At 16 Weeks
Cohort 8: Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)	An AE was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a medicinal product and which did not necessarily have a causal relationship with this treatment. An SAE was defined as any untoward medical occurrence that, at any dose: resulted in death, was life threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity, was a congenital anomaly/birth defect or was medically significant. TEAEs were defined as AEs if one of the following conditions met: emerged after the time of first dose administration, having been absent prior to the first dose; re-emerged, having been present but stopped prior to the time of first dose administration; worsened in severity after the time of first dose administration relative to the pretreatment state, when the AE was continuous.
