Notice of launching of therapeutic agent for hepatocellular carcinoma "MIRIPLA"
Dainippon Sumitomo Pharma Co., Ltd. (Head Office: Osaka, Japan; President: Masayo Tada) launches "MIRIPLA® for intra-arterial injection 70mg" (generic name: miriplatin hydrate), a therapeutic agent for hepatocellular carcinoma in Japan as of January 20, 2010.
"MIRIPLA®" is first suspended in an oily lymphographic agent and then administered through hepatic artery into hepatocellular carcinoma. As such an oily lymphographic agent, the Company has "MIRIPLA® suspension vehicle 4mL" (generic name: iodine addition products of the ethylesters of the fatty acids obtained from poppyseed oil), which is approved for suspending MIRIPLA®. This suspension vehicle is launched at the same time.
"Lipiodolization" or "Chemo-lipiodlization" is one of the standard methods for treating hepatocellular carcinoma where an anticancer drug is suspended in an oily lymphographic agent (iodine addition products of the ethylesters of the fatty acids obtained from poppyseed oil) and then administered into hepatic artery. The Company has carried out a research program to discover an anticancer drug suitable for this treatment and succeeded in development of a lipophilic platinum complex, miriplatin which has high affinity to iodine addition products of the ethylesters of the fatty acids obtained from poppyseed oil.
MIRIPLA® has a high suspensibility in "MIRIPLA® suspension vehicle 4mL ". Some of the characteristics of MIRIPLA® are: it accumulates and stays in a tumor after the administration into hepatic artery, platinum component is released gradually over a long duration and yet exposure to entire body is minor.
In clinical tests on hepatocellular carcinoma, satisfactory anti-tumor effects were confirmed not only on patients of initial treatment but also on patients who relapsed after treatment such as hepatic resection. Some side effects were observed, but they were regarded as those generally observed under chemo-lipiodolization therapy, and they were thought to be tolerable at medical institutions familiarized with this treatment. There was no adverse event on vessel disorder in hepatic artery related to this drug.
The Company has an intention to launch both "MIRIPLA® for intra-arterial injection 70mg" and "MIRIPLA® suspension vehicle 4mL" after they are listed on the national health insurance drug price standard. As a result of launching of MIRIPLA®, the Company expects to increase the line-up of products for the liver diseases, which includes Sumiferon®, a natural interferon-alpha product, and to further contribute to the total care of liver diseases.
