OsteoDex is DexTech's lead candidate for the treatment of castration-resistant prostate cancer and has completed clinical phase 2. In October 2023, the Company filed a patent application with the EPO (European patent office, application No. 23203437.1). The application concerned GMP (Good Manufacturing Practice) manufacturing of OsteoDex. The application has now been approved, and a patent has been granted. The patent is of great importance for the continued clinical development of OsteoDex and future market exclusivity. The patent is valid until 2045 and is very positive for the Company's partnership/out-licensing talks.

"This is gratifying news as OsteoDex's patent protection is a key factor in our partnership discussions. Licensees have a requirement for a longer period of market exclusivity after registration, which we meet with the patent by far," says CEO Anders R Holmberg
