"These funding transactions support our strategy of becoming a fully integrated, commercial biopharmaceutical company, and provide us significant optionality for the future," said Robert Bazemore, president and chief executive officer of Epizyme. "We are well capitalized to fully fund the anticipated launches of tazemetostat for epithelioid sarcoma and follicular lymphoma next year, and further invest in both the continued development of tazemetostat and our epigenetic pipeline. Royalty Pharma has an outstanding reputation for investing in promising, late-stage companies, and we are thrilled to have their support as we head into the next phase of our evolution."

As part of the agreements, Royalty Pharma will make an upfront payment of $100 million for shares of Epizyme common stock based on a price of $15 per share, representing a 27% premium to the prior trading day’s closing price. Epizyme also has an 18-month option to sell an additional $50 million of its common stock to Royalty Pharma at then prevailing prices, not to exceed $20 per share, and Royalty Pharma has a three-year option to purchase an additional 2.5 million shares of Epizyme common stock at $20 per share.

Epizyme and Royalty Pharma have also agreed to reduce the existing royalty rates owed by Epizyme to Royalty Pharma on worldwide sales of tazemetostat outside Japan at specified annual net sales levels. This reduction follows Royalty Pharma’s acquisition of certain future royalty streams on sales of tazemetostat in all regions except for Japan, which Epizyme previously owed to Eisai as part of their April 2015 amended and restated agreement. In addition, Epizyme has assigned to Royalty Pharma the future royalty streams on tazemetostat sales in Japan previously owed to Epizyme by Eisai.

"We are very pleased to partner with Epizyme, particularly given the tremendous progress in advancing tazemetostat over the course of 2019," stated Pablo Legorreta, founder and chief executive of Royalty Pharma. "With impressive data in treating both solid tumors and hematologic malignancies, we share the company’s excitement for tazemetostat’s broad therapeutic potential and are committed to supporting tazemetostat’s further development and anticipated launches to fully maximize its commercial opportunity. We look forward to working closely with this talented team as they transition into a commercial-stage organization."

As part of the transactions, Mr. Legorreta will be appointed to Epizyme’s Board of Directors.

Under a separate agreement, Epizyme has established a $70 million loan facility with Pharmakon Advisors, an affiliate of Royalty Pharma, which will fund the regulatory milestones owed to Eisai for the NDA submissions and U.S. approvals for tazemetostat for epithelioid sarcoma and follicular lymphoma. The facility may be drawn down in up to three tranches in conjunction with achievement of the milestones and is expandable by up to $300 million following approval of tazemetostat in follicular lymphoma, subject to mutual agreement.

For a further description of terms of the transaction agreements, please refer to Epizyme’s Form 8-K filed today.

Wilmer Cutler Pickering Hale and Dorr LLP acted as legal advisor to Epizyme; Goodwin Procter LLP, Dechert LLP and Maiwald Patentanwalts- und Rechtsanwalts GmbH acted as legal advisors to Royalty Pharma; and, Akin Gump Strauss Hauer & Feld LLP acted as legal advisor to Pharmakon Advisors.

On November 4, 2019 ADC Therapeutics SA, a clinical-stage oncology-focused biotechnology company pioneering the development of highly potent and targeted antibody drug conjugates (ADCs) for patients suffering from hematological malignancies and solid tumors, reported that ADCT-402 (loncastuximab tesirine) data have been published in Clinical Cancer Research, a journal of the American Association for Cancer Research (AACR) (Free AACR Whitepaper), in a paper titled, "A Phase 1 study of ADCT-402 (Loncastuximab Tesirine), a Novel Pyrrolobenzodiazepine-Based Antibody Drug Conjugate, in Relapsed/Refractory B-Cell Non-Hodgkin Lymphoma (Press release, ADC Therapeutics, NOV 4, 2019, View Source [SID1234596053])."

The Phase 1 multi-center, open-label, single-arm, dose-escalation and dose-expansion clinical trial demonstrated the significant single-agent clinical activity and manageable tolerability profile of ADCT-402 in patients with CD19-positive relapsed or refractory B-cell non-Hodgkin lymphoma who had failed or were intolerant to established therapies. The published paper includes findings from the dose-escalation part of the trial. Notably, among the 61 patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who were evaluable for efficacy, a 55 percent response rate was observed at doses ≥120 µg/kg. Eighty-seven of the 88 patients enrolled in the trial experienced at least one treatment-emergent adverse event (TEAE). The most common TEAEs were low blood cell counts, fatigue, liver test abnormalities, nausea, rash, shortness of breath and tissue swelling.

Brad S. Kahl, MD, Professor of Medicine at Washington University School of Medicine and lead author of the paper, said, "The first-in-human study of ADCT-402 justified its continued evaluation and identified the initial 150 µg/kg dose for the Phase 2 clinical trial. The promising clinical activity and manageable toxicities observed thus far highlight the potential utility of ADCT-402 as an off-the-shelf therapy for heavily pre-treated patients with DLBCL, a population for which a significant unmet medical need remains."

Jay Feingold, MD, PhD, Senior Vice President, Chief Medical Officer and Head of Oncology Clinical Development at ADC Therapeutics, added, "The publication of early ADCT-402 data in a peer-reviewed journal further validates the potential of our lead product candidate to become an important part of the treatment paradigm for relapsed or refractory DLBCL. With enrollment in our pivotal 145-patient Phase 2 clinical trial of ADCT-402 complete, we plan to submit a Biologics License Application to the U.S. Food and Drug Administration for accelerated approval of ADCT-402 for the treatment of relapsed or refractory DLBCL in patients who have failed two or more treatment regimens in the second half of 2020."

ADCT-402 is also being evaluated in an ongoing Phase 1b clinical trial in combination with ibrutinib for the treatment of relapsed or refractory DLBCL or mantle cell lymphoma (MCL) and a Phase 1b clinical trial in combination with durvalumab for the treatment of relapsed or refractory DLBCL, MCL and follicular lymphoma.

About ADCT-402

ADCT-402 (loncastuximab tesirine) is an antibody drug conjugate (ADC) composed of a humanized monoclonal antibody directed against human CD19 and conjugated through a linker to a pyrrolobenzodiazepine (PBD) dimer cytotoxin. Once bound to a CD19-expressing cell, ADCT-402 is designed to be internalized by the cell, following which the warhead is released. The warhead is designed to bind irreversibly to DNA to create highly potent interstrand cross-links that block DNA strand separation, thus disrupting essential DNA metabolic processes such as replication and ultimately resulting in cell death. CD19 is a clinically validated target for the treatment of B-cell malignancies. ADCT-402 is being evaluated in a pivotal Phase 2 clinical trial in patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) (NCT03589469), a Phase 1b trial in combination with ibrutinib in patients with R/R DLBCL or mantle cell lymphoma (MCL) (NCT03684694) and a Phase 1b trial in combination with durvalumab in patients with R/R DLBCL, MCL or follicular lymphoma (NCT03685344). The U.S. Food and Drug Administration granted orphan drug designation to ADCT-402 for the treatment of relapsed or refractory DLBCL and MCL.

The private placement was led by BVF Partners L.P., with significant additional participation from EcoR1 Capital, Aquilo Capital Management, Surveyor Capital (a Citadel company), and Samsara BioCapital.

The private placement will consist of 9,014,960 units, at a price of $3.55 per unit. Each unit will consist of (i) one share of Pieris’ common stock or 0.001 non-voting Series C convertible preferred stock, and (ii) one immediately-exercisable warrant to purchase one share of common stock at an exercise price of $7.10 per share. Each share of non-voting Series C convertible preferred stock is convertible into 1,000 shares of Pieris common stock, provided that conversion will be prohibited if, as a result, the holder and its affiliates would own more than 9.99% of the total number of shares of Pieris common stock then outstanding.

The warrants are intended to facilitate Pieris’ exercise of its co-development option for PRS-060/AZ1402 following the conclusion of a positive phase 2a study. If top-line results of that study disclose achievement of the primary efficacy endpoint and the stock reaches a pre-specified price, then the warrants will expire sixty days following such disclosure and may only be exercised for cash. Otherwise, the warrants will be exercisable for a period of five years from the date of issuance.

The closing of the financing is expected to take place on or about November 6, 2019 and is subject to standard closing conditions. Pieris expects to use the proceeds from the financing for continued development of its immuno-oncology franchise, including PRS-343, its 4-1BB/HER2 bispecific, and PRS-344, its 4-1BB/PD-L1 bispecific in co-development with Servier. The Company also expects to use these proceeds for advancement of its proprietary pipeline of inhalable respiratory drug candidates following proof-of-mechanism with respect to PRS-060/AZ1402, validating the inhaled Anticalin platform as a potential drug class, as well as for working capital and general corporate purposes.
