TOKYO, July 10 Sosei Group Corporation("Sosei"; TSE Mothers Index: 4565), the biopharmaceutical company, todayannounced the completion of a Japanese Phase III clinical trial for theemergency contraceptive pill (ECP) SOH-075 (NorLevo(R)). Sosei acquired theexclusive distribution rights to the product in Japan from HRA Pharma.

The clinical study was designed to evaluate the safety and preventedpregnancy rate of SOH-075 in Japanese adult female subjects who requireemergency contraception. No serious adverse events were reported during thestudy.

NorLevo(R) is an oral emergency contraceptive "morning after pill" whichis used to prevent pregnancy after unprotected intercourse. NorLevo(R)contains only levonorgestrel as an active ingredient. The dosing is startedwithin 72 hours after unprotected sexual intercourse. NorLevo(R) was firstlaunched in Europe in 1999 and is currently approved in some 60 countries,the product being both well-tolerated and effective as an oral emergencycontraceptive for post-coital use.

"We are delighted to announce the completion of Phase III trial ofSOH-075, which will be the first ECP to be introduced into Japan. We believethat this product will meet one of the needs of Japanese women and that thetrial will confirm that NorLevo(R) is as safe and effective in thispopulation as has already been demonstrated in other countries," said MrShinichi Tamura, Chief Executive Officer of Sosei.

Andre Ulmann, CEO of HRA Pharma added: "We're very proud of reaching thisimportant milestone in Japan. We hope that, access to emergency contraceptionwill benefit Japanese women and families by improving reproductive health."

Editor's notes:


ECP is necessary for women who may be concerned about the possibility ofan unwanted pregnancy following unprotected intercourse. Two largemultinational studies, aiming to test a 12-24h regimen (Lancet, 1999) and asingle administration (Lancet, 2002), both performed by the World HealthOrganisation (WHO) demonstrated that levonorgestrel mono therapy, such asNorLevo(R), was well-tolerated and more effective than the Yuzpe method(ethinyl estradiol and levonorgestrel), a traditional emergency contraceptionmethod used since 1977. Levonorgestrel mono therapy for emergencycontraception is listed as an essential drug by the WHO.
