Epizyme to Present Updated Data from Ongoing Phase 1 Dose Escalation Trial of EZH2 Inhibitor EPZ-6438 at International Conference on Malignant Lymphoma

CAMBRIDGE, Mass.--()--Epizyme, Inc. (NASDAQ:EPZM), a clinical stage biopharmaceutical company creating novel epigenetic therapies for cancer patients, announced today that updated data from the Phase 1 portion of the ongoing Phase 1/2 study of EPZ-6438 will be presented during the 13th International Conference on Malignant Lymphoma (ICML), to be held in Lugano, Switzerland, June 17-20, 2015. EPZ-6438 is a first-in-class EZH2 inhibitor that Epizyme is currently studying in patients with advanced B-cell non-Hodgkin lymphomas (NHL) or advanced solid tumors.

Phase 1 study of EPZ-6438, an Enhancer of Zeste-Homolog 2 (EZH2) Inhibitor: Dose determination and preliminary activity in Non-Hodgkin Lymphoma
Speaker: Vincent Ribrag, M.D., Institut Gustave Roussy, Villejuif, France
Session Title: Session 13: Targeting Intracellular Pathways
Presentation Time: Saturday, June 20, 10:35 a.m. CET

About EZH2 Cancers

EZH2 is a histone methyltransferase (HMT) that is increasingly understood to play a potentially oncogenic role in a number of cancers. These include non-Hodgkin lymphomas; INI1-deficient cancers such as malignant rhabdoid tumors, epithelioid sarcomas and synovial sarcoma; and a range of other solid tumors.

About EPZ-6438

Epizyme is developing EPZ-6438, a small molecule inhibitor of EZH2 created with our proprietary product platform, for the treatment of non-Hodgkin lymphoma patients and patients with INI1-deficient solid tumors. In many human cancers, misregulated EZH2 enzyme activity results in misregulation of genes that control cell proliferation — without these control mechanisms, cancer cells are free to grow rapidly.

EPZ-6438 is the second HMTi to enter human clinical development (following Epizyme's DOT1L inhibitor, EPZ-5676).

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.
