CHUGAI-PHARMA-EUROPE

Chugai Pharma Europe Ltd. (CPE), a wholly owned subsidiary of Chugai Pharmaceutical Co., Ltd. (TOKYO:4519), announced today positive results of a Phase III clinical trial called “ADMYRE” conducted by PharmaMar, with Aplidin^® (plitidepsin) in combination with dexamethasone versus dexamethasone alone in patients with relapsed/refractory multiple myeloma (MM). The study achieved its primary endpoint with a statistically significant extension in progression free survival (PFS) compared with dexamethasone alone, as announced by PharmaMar on 31 March.

For a long time, CPE has been committed to the treatment of hematologic oncology. It obtained promotion rights of Aplidin for the treatment of MM in eight European countries (France, Germany, the UK, Belgium, the Netherlands, Luxemburg, Ireland and Austria) under a licensing agreement with PharmaMar in July 2014.

"This is a positive step forward for our shared vision with PharmaMar to introduce a new treatment for relapsed Multiple Myeloma and we are confident that Aplidin's mechanism of action and strong supporting data will lead to a successful introduction of this novel drug for the benefit of patients" said John Halls, Managing Director of Chugai Pharma Europe.

This pivotal, randomized, open-label, international, multicenter Phase III clinical trial enrolled 255 patients in 83 medical centers across 19 countries (including the U.S, Europe and Asia-Pacific) with relapsed or relapsed and refractory multiple myeloma after at least three but no more than six prior therapeutic regimens for MM. A full evaluation of the final ADMYRE data will be presented at an upcoming medical meeting.

About multiple myeloma

Multiple myeloma is a relatively uncommon type of blood cancer, which accounts for 10% of all hematological malignancies, that is caused by malignant plasma cells that very rapidly multiply¹ . Normal plasma cells are white blood cells, which form part of the immune system, found in the bone marrow that produces the antibodies necessary to fight infections² . Abnormal cells produce a type of antibody that does not benefit the body and accumulate, thus preventing normal cells from functioning properly. Almost all patients with multiple myeloma progress from an initial, asymptomatic pre-malignant stage to established disease. In 2015, 26,850 new cases were diagnosed in the US, and about 11,200 people died of this disease³ . In Europe, the incidence is 4.5–6.0 out of 100,000 diagnosed per year⁴ .

About APLIDIN ^® (plitidepsin)

Plitidepsin is an investigational anticancer agent of marine origin, originally obtained from the ascidian Aplidium albicans . It is a first-in-class drug specifically targeting eEF1A2 in tumor cells. Plitidepsin is currently in clinical development for hematological cancers, including this Phase III study in relapsed or refractory multiple myeloma, a Phase Ib trial in relapsed or refractory multiple myeloma as a triple combination of plitidepsin, bortezomib and dexamethasone, and a Phase II study in relapsed or refractory angioimmunoblastic T-cell lymphoma. Plitidepsin has received orphan drug designation by the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA).
