Enrollment of Patients Completed in Multiple Tazemetostat Combination Studies

EU Orphan Designations Received for Tazemetostat

Conference Call to be Held on May 17, 2018 at 9:30 a.m. ET

CAMBRIDGE, Mass., May 08, 2018 (GLOBE NEWSWIRE) -- Epizyme, Inc. (NASDAQ:EPZM), a clinical-stage company developing novel epigenetic therapies, today reported financial results for the first quarter of 2018 and provided a business update.

“We made meaningful progress with tazemetostat’s development in the first quarter and strongly believe in its potential to improve the treatment of a range of solid tumors and hematologic malignancies,” said Robert Bazemore, president and chief executive officer of Epizyme. “Our attention now is squarely focused on a set of actions intended to address the partial clinical hold that has paused new patient enrollment in our trials. We look forward to presenting new clinical data at multiple medical meetings in the second quarter and remain on track for a catalyst-rich year that we expect will culminate in our first New Drug Application targeted for submission in the fourth quarter of 2018.”

Clinical Program Status

As reported on April 23, 2018, following a safety report of a pediatric patient who developed a secondary T-cell lymphoma in the company’s ongoing Phase 1 clinical trial of tazemetostat in pediatric patients, the U.S. Food and Drug Administration (FDA) issued a partial clinical hold on new enrollment of U.S. patients in the company’s ongoing trials. Epizyme was advised of a similar action by the French National Agency for Medicines and Health Products Safety (ANSM) late last week. Under these regulatory actions, patients on study who have not experienced disease progression may be able to continue to receive tazemetostat. More than 750 patients have been treated with tazemetostat to date, and this is the only case of secondary lymphoma that has been observed across the tazemetostat clinical program. Epizyme is working diligently to address the hold on new patient enrollment, including updating the informed patient consent form, investigator’s brochure and study protocols, and will need to confirm alignment with U.S. and French regulators in order to resume enrollment.

Recent Progress

  • Enrollment in Prednisolone Combination Cohort Completed:Epizyme completed enrollment of 71 wild-type EZH2 patients in its cohort investigating tazemetostat in combination with the steroid prednisolone for relapsed or refractory diffuse large B-cell lymphoma (DLBCL). This cohort is included in the company’s ongoing Phase 2 international trial in relapsed or refractory non-Hodgkin lymphoma (NHL).
  • Enrollment in Atezolizumab Combination Trial Completed: Enrollment of 45 patients with relapsed or refractory DLBCL was completed in a Phase 1b trial investigating tazemetostat in combination with atezolizumab, a PD-L1 inhibitor. This study was initiated based on preclinical findings that EZH2 inhibition may enhance the activity of checkpoint inhibitors, and is being conducted by Genentech, a division of Roche, under a collaboration agreement between Epizyme and Genentech.
  • European Orphan Drug Designations Granted:The European Commission (EC) has granted orphan drug designation to tazemetostat for the treatment of patients with follicular lymphoma, DLBCL and malignant mesothelioma. This designation is granted by the EC to medicines being developed for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition with an EU prevalence of not more than five in 10,000 people.

Upcoming Clinical Data Presentations and Conference Call

Epizyme plans to present updated interim clinical data from its tazemetostat development program at multiple medical meetings in the second quarter of 2018, including data from its ongoing Phase 2 trial in malignant mesothelioma at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting from June 1-5 in Chicago. The company plans to host a conference call and webcast at 9:30 a.m. ET on May 17, 2018 to discuss recent corporate updates and tazemetostat clinical data that will be included in abstracts for upcoming medical meetings, including ASCO. To participate, please dial (877) 844-6886 (domestic) or (970) 315-0315 (international) and refer to conference ID 3058627. A live webcast will be available in the investor section of the company’s website at The webcast also will be archived on the website for 60 days.
First Quarter 2018 Financial Results

  • Cash Position: Cash, cash equivalents and marketable securities were $247.9 million as of March 31, 2018, which compares to $276.4 million as of December 31, 2017.
  • Revenue: No revenue was recognized in the first quarters of 2018 or 2017.
  • R&D Expenses: Research and development (R&D) expenses were $25.6 million for the first quarter of 2018, which compares to $24.7 million for the first quarter of 2017. The increase is primarily due to increased tazemetostat manufacturing and clinical development activities, as well as research related to advancing the company’s preclinical G9a inhibitor program.
  • G&A Expenses: General and administrative (G&A) expenses were $9.4 million for the first quarter of 2018, which compares to $8.3 million for the first quarter of 2017. The increase is primarily due to increased headcount and related expenses, as well as expanded pre-commercial activities.
  • Net Loss: Net loss was $34.1 million, or $0.49 per share, for the first quarter of 2018 which compares to $32.5 million, or $0.56 per share, for the first quarter of 2017.

Financial Guidance
Epizyme continues to expect that its existing cash, cash equivalents and marketable securities as of March 31, 2018 will be sufficient to fund its planned operations into the third quarter of 2019.
