History

Chordate Medical is a Swedish medical technology company that has spent more than ten years developing the Ozilia® treatment, which is based on Kinetic Oscillation Stimulation (KOS), a technique for treating chronic migraine and chronic rhinitis. The company is registered as Chordate Medical Holding AB (publ), company number 556962-6319, and is listed on the Nasdaq First North Growth Market in Stockholm under the ticker CMH. Ozilia® was initially developed and CE-marked exclusively as a treatment for rhinitis. Over time, doctors observed that many patients also experienced improvement in their migraine symptoms, which led the company to investigate how Ozilia® could be used against chronic migraine. The rhinitis treatment has been CE-marked for a long time and is available in the Nordics, on selected markets in the EU, in Israel and in Saudi Arabia. The migraine indication reached a major milestone in May 2021, when Ozilia® received CE marking for the preventive treatment of chronic migraine in adults over 18 years of age, more than a year earlier than the initial plan. In August 2021, the Ozilia® Migraine treatment began to be used for the treatment of chronic migraine in regular clinical practice in Sweden. Marketing and introduction of the migraine indication is now taking place in Germany, the UK, Italy, Israel and Finland, and the treatment is sold in selected European markets as well as in Israel. A clinical study was finalized in July 2022, with indications described as very positive. Chordate Medical has built a patent portfolio covering Ozilia® in the EU and the United States, as well as in many other countries. The company describes its strategy as building value for an exit by expanding its patent portfolio, carrying out clinical trials and demonstrating commercial traction. Chordate Medical operates in the neurostimulation/neuromodulation sector, which it expects to be worth around SEK 132.8 billion globally in 2024. It targets the global migraine drug market, which it expects to be worth around SEK 83.7 billion a year within the next five years. The company's premises are at Kista Science Tower, Färögatan 33, Kista, Sweden. Its annual general meeting in 2025 was held on 21 May 2025, and an extra general meeting was scheduled for 24 April 2026.
