Cevira® data published in American Journal of Obstetrics & Gynecology

Phase 2b results demonstrate significant and sustained efficacy in treating human papilloma virus and precancerous lesions of the cervix.

Oslo, Norway, 4 November 2014:  Photocure ASA (OSE: PHO), a specialty pharmaceutical company focused on photodynamic technologies in dermatology and cancer, announces the Phase 2b study of Cevira in patients with human papilloma virus (HPV) related disease of the cervix, has been published in the prestigious American Journal of Obstetrics and Gynecology.

Cevira, a novel and easy to use integrated drug-delivery device, demonstrated significant and sustained efficacy in the eradication of oncogenic HPV infections and precancerous lesions in CIN2 patients as compared to placebo.

Kjetil Hestdal, President and CEO of Photocure, said: “There is a high unmet medical need for a therapeutic alternative for the large number of women globally who suffer from HPV infections. The easy to use technology, high patient and gynecologist acceptance will allow this treatment to be used widely. The publication of this data in such an esteemed journal is testament to the potential of Cevira as a promising new treatment option, and endorses our ongoing partnership discussions for Cevira’s development and commercialization.”

Oncogenic HPV infection is the most common sexually transmitted disease causing approx. 500,000 new cases of cervical cancer annually world-wide. CIN1 is a mild, low-grade lesion caused by persistent oncogenic HPV infections. High-grade lesions - CIN2, CIN3, or CIN2/3 - are more severe precancerous abnormalities that have a higher likelihood of progressing to cancer if left untreated. Standard treatment for CIN2/3 is surgical intervention which negatively impacts the function of the cervix leading to an increased risk of miscarriages and preterm births.

Professor Peter Hillemanns, Head of Department of Gynecology and Obstetrics at the Medical University of Hannover, Germany and Principal Investigator, said: “The increased morbidity from surgical treatment of precancerous lesions of the cervix is well established. There is a need for well tolerated and convenient therapeutic alternatives. Cevira is a promising product as a potential treatment in the large group of women in need of cervix preserving treatments.”

The final study results were announced in April 2013. The Phase 2b trial was carried out in 262 patients with low to moderate grade cervical intraepithelial neoplasia (CIN1/2) caused by oncogenic Human papilloma virus (HPV) infections. It demonstrated a statistically significant and sustained lesion response compared to placebo in patients with precancerous CIN2 lesions, 95% vs 62% respectively at six months, (p<0.02). This was further supported by high clearance of the highest risk oncogenic HPV subtypes 16 and 18 in the CIN2 cohort, of 83% vs 33% at six months. Additionally, high clearance of HPV 16 and 18 was also demonstrated in the overall CIN1/2 population, 62% vs. 33% as compared to placebo.
