Shionogi Concludes Licensing Agreements with Eddingpharm for Lusutrombopag, a Thrombopoietin Receptor Agonist

OSAKA,Japan,June 24,2019 --Shionogi & Co.,Ltd. (hereafter "Shionogi" or "the Company") announces that the Company has concluded an agreement with Eddingpharm (hereafter "Eddingpharm") to license-out lusutrombopag,a thrombopoietin receptor agonist (brand name in Japan: MULPLETA®).

Licensing agreement of lusutrombopag with Eddingpharm

In China,about 13.61,2,3 million adult patients have chronic liver disease and many of them are said to be planning to receive elective invasive therapy. On the other hand,the country faces a chronic shortage of blood for transfusions due to a growing demand for blood duringadvanced higher-level medical care,in addition to a lower rate of voluntary blood donation as compared to Europe,the U.S.,and Japan. Additionally,it is also known that the current storedblood supply in China is at high risk of transfusion-transmitted infections. Under such circumstances,the application of lusutrombopag is a preferable mode of therapy versus platelet transfusion.

Eddingpharm is a pharmaceutical company with a broad-based sales network that covers hospitals nationwide specializing in liver disease,blood disorders,and infections where prescriptions of lusutrombopag are expected. Following product approval,it is anticipated that the two parties will further contribute to clinical treatment of patients in China by leveraging Eddingpharm's broad sales network and Shionogi's know-how in developing and marketing lusutrombopag globally. With the execution of this agreement,Eddingpharm will be granted withexclusive license rightof lusutrombopag in Mainland China,Hong Kong,and Macau while Shionogi will supply the product to Eddingpharm and receive an upfront payment as well as milestone payments according to post-launch sales periods. It is also agreed that the two companies will cooperate on the application for approval. The Company has been proceeding with preparations toward the application for approval of the product in China.

"We are very excited about this collaboration. This collaboration is an important milestone for patients in China living with chronic liver disease,bringing a well-tolerated and effective treatment option for severe thrombocytopenia that facilitates the management of invasive procedures one step closer to these patients.",said Dr. Isao Teshirogi,President and Chief Executive Officer,Shionogi & Co.,Ltd.

About Thrombocytopenia in Chronic Liver Disease

Thrombocytopenia is a common complication of chronic liver disease (CLD) and may be caused by multiple mechanisms including splenic sequestration and decreased production of thrombopoietin3. There is evidence that the annual health care cost of a CLD patient with thrombocytopenia is more than three times that of a CLD patient without thrombocytopenia4. In addition to the potential of thrombocytopenia,especially severe thrombocytopenia,to aggravate procedural or traumatic bleeding,it may also significantly complicate routine diagnostic procedures and patient care,such as liver biopsy and medically indicated or elective procedures for cirrhotic patients,resulting in delayed or cancelled curative treatment5.
