Sales Contract With Genzyme Finalized: Antipostoperative Adhesion Agent “Seprafilm” to Be Marketed by KAKENFebruary 24, 1997

 KAKEN PHARMACEUTICAL CO., LTD. ( head office: Tokyo ) finalized a contract with Genzyme Corporation ( head office: Massachusetts ) and Genzyme Japan K.K. ( head office: Tokyo ) on February 18, 1997 for cooperative marketing of Genzyme’s “Seprafilm”, a preparation for prevention of postoperative adhesion.

 

 Occurring in about 95% of all operations and causing intestinal adhesion, infertility, pain and many other complications, postoperative adhesion is a major medical problem. Adhesion also makes repeat surgery difficult. At present, there is no effective method of preventing adhesion. KAKEN has decided to market this product because it offers medicoeconomic advantages and significantly relieves patients’ pain and discomfort.

 

 Seprafilm is already marketed in the US, Canada and Europe. In Japan, Genzyme Japan filed an application in July 1996. KAKEN has obtained the marketing right in Japan. Inclusion in the NHI drug price list is expected at the end of this year.

 

 In addition to Seprafilm, the KAKEN – Genzyme agreement includes Sepracoat, a liquid formulation marketed in Europe. KAKEN has also obtained an option right for Sepragel, a gel formulation under development in the US and Europe.

 

1.   Information on adhesion
 Adhesion often occurs after surgery due to scarring of internal tissues. Organs and adjacent tissues, which are normally separate, adhere. Adhesion makes subsequent surgery difficult and is sometimes life-threatening. Adhesion often causes serious complications, such as intestinal adhesion, infertility in women and chronic pain.
