Sawai and Neurolief enter into Exclusive Development and Marketing Agreement for Relivion

Osaka, Japan – January 28, 2021 – Sawai Pharmaceutical Co., Ltd. (Sawai, Head office: Osaka, Japan, President: Kenzo Sawai) announced that it has entered into an exclusive development and marketing agreement with Neurolief Ltd. (Neurolief, Head office: Netanya, Israel, Chairman: Chris Richardson) for Relivion, a non-invasive digital medical device for migraine and depression.

Relivion is a non-invasive brain neuromodulation* device that is placed around the head and delivers unparalleled stimulation to the occipital and trigeminal nerves. This creates a cumulative effect by releasing neurotransmitters in the brainstem and modulating brain networks associated with control of pain and mood. Patients can use Relivion at home, and can share treatment data with their physician, in addition to uploading the data to the cloud database through a dedicated app. It is also designed to self-learn and analyze the treatments using AI technology in order to optimize the treatments for patients according to their symptoms. *Neuromodulation: A therapeutic technology to modulate neurological activities through the administration of electric/magnetic stimuli or drugs.

With the view to its launch in Japan, the applications are scheduled to be submitted to the Pharmaceuticals and Medical Devices Agency (PMDA) for migraine by 2022 and depression by 2023. If Relivion is approved by the agency, it will be the only brain neuromodulation device available for treatment at home in Japan. *In Europe, Neurolief obtained the CE Mark certification as a treatment device for migraine and is in preparation for the market launch. In the US, the application was filed to FDA in November 2020 as a 510(K) submission for migraine and is scheduled to be filed for depression by 2022.

Under the corporate philosophy of “Always Putting Patients First”, we strive to contribute even more to healthier lives with a novel neuromodulation treatment option, which is not yet well-known in Japan. By introducing the Relivion for use at home with doctor’s supervision, we are widening treatment options for patients who are suffering from either migraine or depression.
