About Epizyme, Inc.Epizyme, Inc. is a clinical stage biopharmaceutical company creating novel epigenetic therapeutics for cancer patients. Epizyme has built a proprietary product platform that the Company uses to create small molecule inhibitors of a 96-member class of enzymes known as histone methyltransferases, or HMTs. HMTs are part of the system of gene regulation, referred to as epigenetics, that controls gene expression. Genetic alterations can result in changes to the activity of HMTs, making them oncogenic (cancer-causing). By focusing on the genetic drivers of cancers, Epizyme's targeted science seeks to match the right medicines with the right patients.For more information, visit www.epizyme.com and connect with us on Twitter at @EpizymeRx.

Epizyme, Inc. (NASDAQ: EPZM), a clinical stage biopharmaceutical company creating novel epigenetic therapies for people with cancer, today announced that the U.S. Food and Drug Administration has accepted the company's Investigational New Drug (IND) application for tazemetostat for the treatment of adults with mesothelioma characterized by BAP1 loss-of-function. In the third quarter of this year, the company plans to initiate a phase 2 study in patients with mesothelioma. "We are moving quickly to expand the tazemetostat clinical program into mesothelioma, adding to our ongoing studies in non-Hodgkin lymphoma and certain genetically defined solid tumors," said Robert Bazemore, President and Chief Executive Officer, Epizyme. "We believe that tazemetostat has the potential to treat multiple types of cancer in patients who have limited treatment options. We look forward to starting the mesothelioma phase 2 study later this year." Tazemetostat is a first-in-class small molecule inhibitor of EZH2 created by Epizyme using its proprietary drug development platform. Aberrant EZH2 activity results in misregulation of genes that control cell proliferation and has been associated with a diverse set of human cancers. Emerging preclinical findings from published reports suggest that mesothelioma, and particularly mesothelioma characterized with BAP1 loss of function, may be sensitive to EZH2 inhibition 1. Mesothelioma characterized by BAP1 loss of function accounts for 40-60 percent of the approximately 12,000 new mesothelioma cases each year in major markets 2-5. About the Tazemetostat Clinical Trial ProgramTazemetostat, a first-in-class EZH2 inhibitor, is currently being studied in ongoing phase 2 programs in both non-Hodgkin lymphoma (NHL) and certain genetically defined solid tumors, including INI1-negative and SMARCA4-negative tumors and synovial sarcoma. The company has announced plans to initiate additional clinical evaluations of tazemetostat in 2016, including a combination with R-CHOP in patients with diffuse large B-cell lymphoma (DLBCL) and a combination with an immune checkpoint inhibitor in NHL.
