Epizyme Announces FDA Filing Acceptance of New Drug Application and Priority Review for Tazemetostat for the Treatment of Epithelioid Sarcoma
CAMBRIDGE, Mass.--(BUSINESS WIRE)--Jul. 25, 2019-- Epizyme, Inc. (Nasdaq: EPZM), a late-stage biopharmaceutical company developing novel epigenetic therapies, today announced that the U.S. Food and Drug Administration (FDA) has accepted for filing the company’s New Drug Application (NDA) for accelerated approval of tazemetostat, its lead investigational agent. Epizyme has proposed an indication of metastatic or locally advanced epithelioid sarcoma not eligible for curative surgery. The FDA granted Priority Review for the NDA and has set a Prescription Drug User Fee Act (PDUFA) target action date of January 23, 2020. Priority Review is granted to investigational therapies that, if approved, may offer significant improvements in the treatment, prevention or diagnosis of a serious condition.
“We are thrilled with FDA’s acceptance of this first tazemetostat NDA submission for priority review, and to be an important step closer to achieving our mission of rewriting treatment for patients with cancer and other serious diseases,” said Robert Bazemore, president and chief executive officer of Epizyme. “This is a significant achievement in the development of this potentially first-in-class EZH2 inhibitor, and we look forward to working with FDA during the review. If approved, we believe tazemetostat could become an important new option in the treating physicians’ arsenal. We would like to extend our sincerest gratitude to those patients, families and medical teams who have participated in our clinical studies and helped bring tazemetostat to this stage.”
Epizyme’s NDA submission is based primarily on data from the 62 patient epithelioid sarcoma cohort of its ongoing Phase 2 study of tazemetostat. These data, recently reported at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting, showed that tazemetostat treatment resulted in clinically meaningful and durable responses, and was generally well-tolerated.
To support full approval of tazemetostat for epithelioid sarcoma, Epizyme will initiate a global confirmatory trial. The company plans to conduct a 1:1 randomized, controlled clinical trial in the front-line treatment setting comparing tazemetostat in combination with doxorubicin versus placebo plus doxorubicin in approximately 150 patients. The primary efficacy endpoint will be progression-free survival, and secondary efficacy endpoints will include overall survival, disease control rate, overall response rate and duration of response. The confirmatory study will include a safety run-in that is expected to begin in the second half of 2019.
About the Tazemetostat Clinical Trial Program
Tazemetostat, an oral, potent, first-in-class EZH2 inhibitor, is currently being studied as a monotherapy in ongoing clinical programs in patients with certain molecularly defined solid tumors, including epithelioid sarcoma and other INI1-negative tumors, and in patients with follicular lymphoma, both with and without EZH2 activating mutations. Multiple clinical studies are underway through collaborations assessing tazemetostat as a combination treatment for patients with diffuse large B-cell lymphoma. Epizyme also plans to conduct multiple additional clinical trials designed to evaluate the potential benefit of tazemetostat in earlier lines of therapy for follicular lymphoma, as well as new combinations and cancer indications.
