Mirogabalin: First Global Approval

Mirogabalin besylate (hereafter mirogabalin) [Tarlige®] is an orally administered gabapentinoid developed by Daiichi Sankyo for the treatment of peripheral neuropathic pain (PNP), including diabetic PNP and post-herpetic neuralgia. The drug binds to and modulates the α2δ-1 subunit of the voltage-gated calcium channels widely found in the nervous system in areas that mediate pain transmission and processing. Mirogabalin has a unique binding profile and long duration of action. The drug is approved in Japan for the treatment of PNP and is in clinical development for this indication elsewhere in Asia. Clinical development of the drug for fibromyalgia pain was discontinued in the USA and EU after the primary endpoint was not met in phase 3 trials. No recent reports of development have been identified for PNP in the USA or India or for fibromyalgia pain in Australia, India, New Zealand, Russia, Argentina, Belarus, Chile, Colombia, Israel, Mexico, Switzerland, Canada, Serbia or South Africa. This article summarizes the milestones in the development of mirogabalin leading to this first approval for PNP.
