Our Products

Eisai positions "neurology" and "oncology" as two strategically important areas where we can discover "Ricchi", areas where patients true needs remain unmet and we can become a front-runner. Accordingly, we are promoting drug discovery activities in these two areas.

In addition, Eisai is committed to maximizing value for patients by developing additional formulations / expanding indications of our four global brands: Halaven®, Lenvima®, Fycompa®, and BELVIQ®.

In the neurology area, our in-house discovered and developed antiepileptic drug Fycompa® is approved as an adjunctive therapy for partial-onset seizures in over 55 countries including Japan, the United States, in Europe and in Asia. It is also approved for use as monotherapy for the treatment of partial onset seizures (with or without secondarily generalized seizures) in patients 4 years of age and older in the United States. In addition, Fycompa is approved as an adjunctive therapy for primary generalized tonic-clonic seizures in over 50 countries including Japan, the United States, in Europe and in Asia. Aricept® was first launched in January 1997 in the United States and is now approved in over 100 countries worldwide. Moreover, as a leading pharmaceutical company in the development of dementia treatments, we are also expanding our activities to promote early diagnosis and early treatment of dementia. 

In the oncology area, our in-house discovered and developed anticancer agent Halaven has been approved for use in the treatment of breast cancer in over 65 countries and also for use in the treatment of malignant soft tissue sarcoma in over 50 countries. Lenvima, another anticancer agent discovered and developed in-house, has been approved for use in the treatment of thyroid cancer in over 50 countries, including Japan, the United States, in Europe, and in Asia. Additionally, it has been approved as combination therapy with everolimus for use in the treatment of renal cell carcinoma in over 45 countries including the United States and Europe. (In Europe, the brand name for this indication is Kisplyx®.) Regarding the third indication for use in the treatment of hepatocellular carcinoma, Lenvima was approved for this indication in Japan in March 2018, and in the United States, Europe and South Korea in August 2018, and in China in September 2018.
