Press Release - Oslo, Norway, September 17, 2024: Photocure ASA (OSE: PHO), the
Bladder Cancer Company, announces that its partner Asieris Pharmaceuticals (SSE:
688176) has communicated today that international multicenter Phase III clinical
trial data for its non-surgical treatment for cervical HSIL (High-Grade Squamous
Intraepithelial Lesion) product candidate Cevira[® ](APL-1702) have been
accepted for oral presentation by the International Photodynamic Therapy &
Photodiagnosis Update Conference in Germany on September 17, 2024, focusing on
the efficacy data related to the regression of the histological grade of
cervical precancerous lesions.

The Phase III trial is a prospective, randomized, double blind, placebo
controlled, multi-center clinical study, which has reached its primary efficacy
endpoint and exhibited good safety. Additionally, the study found that at 6
months after the first treatment, the regression rate (RR) in the APL-1702 group
was significantly higher than that in the placebo group (47.0% vs. 29.5%, p <
0.01). Subgroup analysis data also showed that in all HPV-negative, HPV16
-positive, and HPV18/others-positive subgroups, the APL-1702 group demonstrated
favorable rates of histological regression comparing to placebo (64.7% vs.
25.0%, 37% vs. 25.4%, 60.0% vs. 36%). At 6 months after first treatment, the
improvement rate for the two groups were 54% and 36%, respectively (p < 0.01).
Among them, 38% of the subjects had cervical tissue restored to normal tissue at
6 months in the APL-1702 group, while only 19% had restoration to normal tissue
in the placebo group. In the APL-1702 group, 79.1% of subjects had no disease
progression, compared to 67.4% in the placebo group (p = 0.0171).
