Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito; “Eisai”) announced today that it has entered into an agreement with Sloan Pharma, S.à.r.l., Switzerland (“Sloan Pharma”), a wholly-owned subsidiary of US WorldMeds, LLC (Headquarters: Louisville, Kentucky, USA, CEO: Paul Breckinridge Jones), to transfer to Sloan Pharma exclusive development and marketing rights for botulinum toxin type B Neurobloc® (“the agent”) in Europe. Under this agreement, Eisai will receive a one-time payment from Sloan Pharma.


In May 2007, Eisai entered into an agreement with Solstice Neurosciences, LLC for the rights to further develop and commercialize the agent in Europe, and Eisai has been marketing the agent which was approved as a treatment for cervical dystonia in Europe. In 2010, Solstice Neurosciences, LLC was acquired by and reorganized as a wholly-owned subsidiary of US WorldMeds, LLC, which currently markets the agent under the product name MYOBLOC (rimabotulinumtoxinB) Injection in the United States. Transferring the rights for the agent in Europe to Sloan Pharma, which, as part of the US WorldMeds group, has strengths in neurology as well as knowledge of the commercialization and development of pharmaceutical products, will enable greater contributions to cervical dystonia patients in Europe.


In Japan, Eisai has conducted development of the agent and obtained approval for the treatment of cervical dystonia. Eisai has been marketing the agent in Japan under the product name NerBloc® since March 2013 and will continue to do so in the future.


Eisai positions neurology and oncology as key therapeutic areas. By accelerating the development of its innovative new drugs in these areas and pursuing optimal business models to match regional characteristics, Eisai seeks to contribute further to addressing the diverse patient needs of, and increasing the benefits for, patients and their families worldwide.
