Asieris Announces First Patient Treated in Europe in APRICITY, the Multinational Phase III Clinical Trial of APL-1702, Cevira®

SHANGHAI,June 22,2021 -- Asieris Pharmaceuticals(Asieris)today announced dosing of the first patient in Europe in its multinational,multicenter,Phase III clinical trial (APRICITY) of its photodynamic drug-device combination product APL-1702,Cevira® which is being developed for a novel non-surgical treatment of cervicalhigh-grade squamous intraepithelial lesions (HSIL).

HSIL is a pre-cancerous condition caused by a persistent HPV infection. Each year there are approximately 10 million cases of high-grade disease and over 500,000 new cases of cervical cancer worldwide. In China,approximately 2% of women develop HSIL each year.In 2019,the number of women with precancerous cervical lesions in China was approximately 3.5 million,and the compound annual growth rate from 2015 to 2019 was 1.3%. With wider use of cervical cytology and HPV screening,more cervical lesions are detected at precancerous stage,and the number of diagnosed patients is expected to continue to rise in the future. Conventional surgical treatment may cause adverse reactions like bleeding,infection,and organic injury of the cervix,which may cause a series of reproductive dysfunctions such as premature delivery and miscarriage.Currently,no non-surgical approach is available for the treatment of precancerous cervical lesions globally.

In China,the clinical trial application for APL-1702,Cevira® multinational Phase III trial was approved by the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) in July 2020,and the first patient was dosed in November.

"As a local non-surgical treatment option,APL-1702,Cevira® has clear advantages in its safety profile over surgical treatment,which helps patients,especially women of childbearing age,to avoid surgery and its related complications," according to Dr. Xue Yong,MD,PhD,Chief Medical Officer at Asieris. "We will endeavor to accelerate the clinical trial progress and bring this potential novel therapy to patients globally."
