Sumitomo Dainippon, which is based in Japan, will have the rights to market the substance in the country, as well as North America. It may opt to secure the rights to the drug in China as well.
JCR Pharmaceuticals, which is also based in Japan, will also receive royalties on the sales of the drug once it is commercialized.
