Nimorazole is an antimicrobial with activity against anaerobic bacteria and protozoa. Its actions and properties are similar to metronidazole. It has also been used in trials studying the treatment of Hypoxia, Radiotherapy, Hypoxic Modification, Gene Profile, Gene Signature, and Head and Neck Squamous Cell Carcinoma, among others. Azanta is developing, nimorazole, as an oral hypoxic radio-sensitiser for the treatment of patients with head and neck cancer who are undergoing radiotherapy. Previously, nimorazole has been approved for use as an anti-protozoal agent and has been launched worldwide. Nimorazole, for the treatment of head and neck cancer patients undergoing radiotherapy received orphan designation by EMA in 2011.
