EPZM Epizyme Inc

TAZVERIK® (tazemetostat) Net Product Revenue of $11.0 Million for 2Q 2022; Total End User Demand Grew 17% vs. 1Q 2022

First Patient Dosed in the SET-101 Phase 1/1b Study of EZM0414, the Company’s Novel, First-in-Class, Oral SETD2 Inhibitor

Merger with Ipsen Expected to Close in 3Q 2022

Epizyme (Nasdaq: EPZM), a fully integrated, commercial-stage biopharmaceutical company developing and delivering transformative therapies for cancer patients against novel epigenetic targets, today reported second quarter 2022 financial results and provided a business update.

“I am pleased with the progress we made as an organization in the second quarter. In addition to the growth of TAZVERIK net product revenue, we are continuing to advance several of our tazemetostat clinical studies, and we also dosed the first patient in the Phase 1 portion of our SET-101 study with our SETD2 inhibitor candidate. For TAZVERIK, we saw double-digit quarter-over-quarter growth in total end user demand and continued improvement in key metrics suggesting greater prescriber understanding and adoption of TAZVERIK, consistent with our label,” said Grant Bogle, President and Chief Executive Officer. “Most importantly, the quarter brought with it news of Epizyme’s decision to enter into a definitive merger agreement with Ipsen. Through this merger, we expect continued investment in our epigenetic pipeline for the benefit of patients.”

Recent Progress

• TAZVERIK® commercial progress:
  • TAZVERIK generated net product revenue of $11.0 million for the second quarter of 2022, including $8.9 million related to TAZVERIK commercial net sales, representing an increase of approximately 10% when compared to $8.1 million in the first quarter of 2022. Sales of TAZVERIK commercial product for third-party pharmaceutical company use in clinical trials was $2.1 million in the second quarter of 2022.
  • Total end user demand grew 17% in the second quarter of 2022 when compared to the first quarter of 2022, which includes commercial demand and free goods supplied through Epizyme’s patient assistance program. Commercial demand grew 8% when compared to the first quarter of 2022.
  • The amount of free goods supplied to patients through the patient assistance program was approximately 22% of total end user demand for the second quarter of 2022 as compared to approximately 15% in the first quarter of 2022. The free goods level in the second quarter of 2022 was consistent with the second quarter of 2021.

• First patient dosed in the Phase 1 portion of the SET-101 Phase 1/1b study of EZM0414 in multiple myeloma (MM): Dosing of the first patient was recently completed in SET-101, the Phase 1/1b study of EZM0414, Epizyme’s novel, first-in-class, oral SETD2 inhibitor candidate, which is being developed for the treatment of adult patients with relapsed/refractory (R/R) MM and R/R diffuse large B-Cell lymphoma (DLBCL).

• Merger with Ipsen: In June, Ipsen and Epizyme executed a definitive merger agreement under which Ipsen has initiated a tender offer to acquire all outstanding shares of Epizyme for $1.45 per share, plus a contingent value right (CVR) of $1.00 per share. The merger is expected to close by the end of the third quarter of 2022 (subject to the satisfaction of all closing conditions). Additional details can be found in the announcement press release as well as in Epizyme’s recent SEC filings.

Tazemetostat Clinical Updates

• Presented updates from SYMPHONY-1 tazemetostat + R2 combination study in R/R follicular lymphoma (FL) at ASCO 2022: In June, Epizyme presented updated safety and activity data from the Phase 1b portion of the SYMPHONY-1 study at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting. The Phase 1b portion of the study showed continued improvement in both objective and complete response rates, as well as response data for a subgroup of patients who are rituximab-refractory and/or relapsed within 24 months (POD24). The study is open for enrollment globally, and Epizyme anticipates providing longer term follow-up data from the Phase 1b portion of the study at a medical conference later this year.

• CELLO-1 Phase 1b/2 study has completed enrollment; updated safety run-in data expected later in 2022: The Phase 2 randomized portion of the CELLO-1 study (EZH-1101), which is evaluating tazemetostat plus enzalutamide compared to enzalutamide monotherapy in metastatic castration-resistant prostate cancer patients, has completed enrollment with a total of 80 patients. Epizyme expects to present updated data from the safety run-in portion later in 2022.

• LYSA Phase 1/2 combination study has completed enrollment; top-line results expected later in 2022: Enrollment in both the DLBCL and FL arms of this study is complete. The Lymphoma Study Association (LYSA) study is a Phase 1/2 combination study of tazemetostat with R-CHOP in high-risk, front-line FL and DLBCL patients. Epizyme, in collaboration with LYSA, anticipates sharing top-line results from the Phase 2 portion of the study later in 2022.

• ARIA hematological basket study (EZH-1501) open for enrollment: The Company continues to screen patients for ARIA, the Phase 1b/2 basket study evaluating tazemetostat combinations in patients with hematological malignancies.

• Updates on tazemetostat development in China: On August 1, Epizyme’s collaboration partner, HUTCHMED, announced the initiation of a bridging study of tazemetostat in China with the first patient dosed on July 29, 2022. This multicenter, open-label, Phase 2 study will evaluate the efficacy, safety, and pharmacokinetics of tazemetostat for the treatment of patients with R/R FL.

About Non-GAAP Financial Measures

In addition to financial information prepared in accordance with the U.S. generally accepted accounting principles (GAAP), this press release includes the following non-GAAP financial measures: total non-GAAP adjusted operating expenses on a historical basis, non-GAAP adjusted R&D expenses on a historical basis and non-GAAP adjusted SG&A expenses on a historical basis. Epizyme derives these non-GAAP financial measures by excluding certain expenses and other items from the respective GAAP financial measure that is most directly comparable to each non-GAAP financial measure. Specifically, the non-GAAP financial measures exclude stock-based compensation expense and depreciation and amortization of intangibles. The Company’s management believes that these non-GAAP financial measures are useful to both management and investors in analyzing its ongoing business and operating performance. Management does not intend the presentation of these non-GAAP financial measures to be considered in isolation or as a substitute for results prepared in accordance with GAAP, but as a complement to provide greater transparency. In addition, these non-GAAP financial measures may differ from similarly named measures used by other companies.

About EZM0414

EZM0414 is a potent selective, oral, small molecule, investigational drug agent that inhibits the histone methyltransferase, SETD2, which plays a role in oncogenesis. SETD2 methylates histone as well as non-histone proteins, and this activity is involved in several key biological processes including transcriptional regulation, RNA splicing, and DNA damage repair. Based on the preclinical data on SETD2 inhibition by EZM0414 in multiple settings, including high risk t(4;14) multiple myeloma (MM) and in other B-cell malignancies such as diffuse large B-cell lymphoma (DLBCL), the Company is conducting SET-101, a Phase 1/1b study of EZM0414, for the treatment of adult patients with relapsed or refractory MM and DLBCL.
