Hengrui Pharmaceuticals Co. Ltd. licensed its EZH2 inhibitor, SHR-2554, to Treeline Biosciences Inc. in a deal worth more than $700 million. Treeline will be granted worldwide exclusive rights to the lymphoma drug, except for greater China, in exchange for an up-front payment of $11 million, development milestone payments of up to $45 million, and milestone payments of up to $650 million based on annual net sales once commercialization begins.
Ipsen SA’s $247 million buyout of Epizyme Inc., and the recent decision by Nordic Nanovector SA to dump its phase IIb program with CD-37-targeted Betalutin (177Lu lilotomab satetraxetan), served to highlight the hot space of relapsed/refractory follicular lymphoma, where bispecifics have been showing particular promise.
After its $247 million acquisition of Epizyme Inc., Ipsen SA will continue to shop for M&A prospects, said Ipsen CEO David Loew, noting that “the [company’s] firepower has not been absorbed in a significant fashion by this deal,” and the firm might undertake a larger transaction next time in oncology, rare diseases, or neurology.
Hutchmed Ltd. has struck a deal for Epizyme Inc.’s anticancer therapy Tazverik (tazemetostat) that could bring the latter up to $310 million. The agreement gives Hutchmed rights to research, develop, manufacture and commercialize Tazverik in greater China, which covers mainland China, Hong Kong, Macau and Taiwan.
Matthew Ros, chief strategy and business officer for Epizyme Inc., said the company is “not providing specific guidance at the moment” about the sales force that will be deployed to market Tazverik (tazemetostat) in follicular lymphoma (FL), an indication for which U.S. regulators are considering the oral, first-in-class EZH2 inhibitor. “But I can assure you we’ve planned very thoughtfully” about the effort, he said. “That's always been a part of why we thought epithelioid sarcoma [ES] was such a strategically important component of the overall business strategy to get on-the-ground experience.” The sales force numbers 19 for now.
Though they made known their reservations about the patient sample size and queried front-line vs. second-line use of tazemetostat, members of the FDA’s Oncologic Drugs Advisory Committee (ODAC) voted 11-0 to recommend approval of the oral, first-in-class EZH2 inhibitor from Cambridge, Mass.-based Epizyme Inc.
