Upcoming Tazemetostat Clinical Data Presentations

Phase 2 in Molecularly Defined Solid Tumors: Interim efficacy and safety data from study cohorts in Epizyme’s ongoing Phase 2 clinical trial of tazemetostat in adult patients with molecularly defined solid tumors that have reached futility assessment by the Independent Data Monitoring Committee will be reported in two poster presentations at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting taking place June 2-6, 2017 in Chicago. The Company will host a conference call to discuss the data on Thursday, May 18 at 8:30 a.m. ET, after ASCO (Free ASCO Whitepaper) abstracts have been released.

To participate in the conference call, please dial (877) 844-6886 (domestic) or (970) 315-0315 (international) and refer to conference ID 12186629. The webcast, and accompanying slides for the call, will be accessible under "Events and Presentations" in the Investor Relations section of the Company’s website at www.epizyme.com.

Phase 2 in Non-Hodgkin Lymphoma: Interim efficacy and safety data from all five monotherapy study cohorts in Epizyme’s ongoing Phase 2 study of tazemetostat in patients with relapsed or refractory follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL) has been selected for a plenary session on Wednesday, June 14, 2017 at 2:00 p.m. CET (8:00 a.m. ET) at the International Conference on Malignant Lymphoma (ICML) in Lugano, Switzerland. Data from a 62-gene panel biomarker study of tazemetostat in patients with NHL will also be presented in a poster session during ICML. The Company plans to hold a conference call to discuss these clinical findings on Wednesday, June 14 at 10:30 a.m. ET.

To participate in the conference call, please dial (877) 844-6886 (domestic) or (970) 315-0315 (international) and refer to conference ID 15855261.

"Already in 2017, we have made progress in our novel epigenetic pipeline, led by tazemetostat," stated Robert Bazemore, president and chief executive officer. "We have continued to advance tazemetostat in multiple clinical trials in a range of solid tumors and hematological malignancies, and as both a monotherapy and in combination with other anti-cancer agents. We look forward to reporting interim data from our Phase 2 study in molecularly defined solid tumors in our conference call next week and from our Phase 2 study in relapsed or refractory FL and DLBCL in June."

Recent Achievements

In May 2017, the Company earned a $10 million milestone payment from GlaxoSmithKline (GSK). The milestone payment follows GSK’s initiation of GLP toxicology studies for a first-in-class methyltransferase inhibitor discovered by Epizyme and licensed to GSK.
In April 2017, the U.S. Food and Drug Administration (FDA) granted Fast Track designation to tazemetostat for the treatment of patients with relapsed or refractory FL, including patients whose tumors have wild type EZH2 or EZH2 activating mutations. Fast Track designation is intended to provide expedited processes for the development and FDA review of drugs that may reduce development time and costs associated with bringing a drug to market.
In March 2017, Epizyme initiated clinical investigation of tazemetostat in combination with prednisolone in relapsed or refractory patients with DLBCL, based on observed preclinical synergy of the agents. This combination regimen is being conducted as the sixth cohort in the ongoing Phase 2 NHL study.
In January 2017, Epizyme completed enrollment of all wild type EZH2 cohorts in its ongoing Phase 2 study of tazemetostat in patients with relapsed or refractory FL and DLBCL.
First Quarter 2017 Financial Results

Cash Position: Cash, cash equivalents and marketable securities were $211.2 million as of March 31, 2017, as compared to $242.2 million as of December 31, 2016.
Revenue: No revenue was recognized in the first quarter of 2017, compared to $0.5 million for the first quarter of 2016.
R&D Expenses: Research and development (R&D) expenses were $24.7 million for the first quarter of 2017, compared to $17.7 million for the first quarter of 2016. The increase is primarily due to the expansion of the tazemetostat clinical program and advancement of our proprietary research pipeline.
G&A Expenses: General and administrative (G&A) expenses were $8.3 million for the first quarter of 2017, compared to $5.8 million for the first quarter of 2016. The increase is primarily due to higher pre-commercial, intellectual property, business development and product planning expenses.
Net Loss: Net loss was $32.5 million for the first quarter of 2017, compared to $22.9 million for the first quarter of 2016.
2017 Guidance
Epizyme believes, based on its current operating plan, that its cash, cash equivalents and marketable securities of $211.2 million as of March 31, 2017 will be sufficient to fund the Company’s planned operations into at least the third quarter of 2018.

About the Tazemetostat Clinical Trial Program
Tazemetostat, a first-in-class EZH2 inhibitor, is currently being studied in ongoing Phase 2 programs in both follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL) forms of non-Hodgkin lymphoma; certain molecularly defined solid tumors, including epithelioid sarcoma and other INI1-negative tumors; and mesothelioma, as well as in combination studies in DLBCL. Tazemetostat has been granted Fast Track designation by the U.S. Food and Drug Administration for the treatment of patients with relapsed or refractory FL, either wild type EZH2 or with EZH2 activating mutations, and for relapsed or refractory DLBCL with EZH2 activating mutations, as well as Orphan Drug designation for malignant rhabdoid tumors.
