CAMBRIDGE, Mass.--(BUSINESS WIRE)--Epizyme, Inc. (Nasdaq: EPZM), a late-stage biopharmaceutical company developing novel epigenetic therapies, today announced that it has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for accelerated approval of tazemetostat for the treatment of patients with metastatic or locally advanced epithelioid sarcoma not eligible for curative surgery. Tazemetostat is an oral, first-in-class, EZH2 inhibitor discovered by Epizyme and being developed for a range of cancers and treatment settings.
This NDA submission follows a recently conducted pre-NDA meeting held with FDA, in which the Agency considered the proposed clinical package to be sufficient for inclusion with the NDA. The submission is based on updated tazemetostat efficacy and safety data from 62 patients enrolled in the epithelioid sarcoma cohort of the Phase 2 clinical trial, which will be reported in an oral presentation at the American Society of Clinical Oncology (ASCO) 2019 Annual Meeting. The company’s ongoing Phase 2 study cohort is the largest prospective clinical trial in epithelioid sarcoma with any approved or investigational anticancer treatment to date.
“Epithelioid sarcoma is a rare and aggressive cancer that affects people in the prime of their lives, and we are very pleased to have recently submitted the NDA for tazemetostat for the treatment of people with this devastating cancer,” said Dr. Shefali Agarwal, chief medical officer of Epizyme. “If approved, we believe tazemetostat has the potential to change the care of patients with this disease. We are incredibly grateful to the physicians and clinical teams who have helped advance tazemetostat to this stage, and, most notably, to the patients and caregivers who have participated in our clinical trials along the way. We look forward to continuing to engage with the FDA as we work to bring tazemetostat to patients and physicians in the U.S.”
To support a full approval of tazemetostat for epithelioid sarcoma, Epizyme plans to conduct a global, randomized, controlled trial, that it expects to begin in the second half of 2019. The final design of the study is subject to alignment with FDA, and the company plans to disclose details once it has reached alignment with FDA and the NDA submission has been accepted for review. The FDA has a 60-day filing review period to determine whether the NDA is complete and acceptable for filing.
“At Epizyme, our mission is to deliver new treatments for patients with cancer and other serious diseases, and today we stand one significant step closer to achieving that,” said Robert Bazemore, president and chief executive officer of Epizyme. “This submission is the culmination of years of hard work by our entire team, and I wish to congratulate them all on this accomplishment. Our epithelioid sarcoma program is strategically valuable to Epizyme and helps streamline our planned NDA submission in the fourth quarter, for patients with follicular lymphoma. Over the coming months, we have multiple anticipated clinical data and regulatory milestones, and we are well underway with commercialization readiness activities to support the potential launch of tazemetostat and our transition to a commercial-stage organization. 2019 is set to be a transformational year for Epizyme, and I am enthusiastic for our continued progress.”
About Epithelioid Sarcoma
Epithelioid sarcoma is an
ultra-rare soft tissue sarcoma characterized by a loss of the protein
INI1. Patients are most commonly diagnosed as young adults, between 20
and 40 years of age. Median overall survival from initial diagnosis is
30 months. Epithelioid sarcoma becomes more aggressive after recurrence
or metastases, with a typical survival of less than one year for
patients with metastatic disease.
