Funding to accelerate commercial growth and expand clinical and health economic evidence for ReActiv8® Restorative NeuromodulationTM System

Mainstay Medical Holdings plc today announced an equity financing in which it will receive gross proceeds of US$125 million. Mainstay intends to use the funds to support the company’s continued commercial growth of ReActiv8® Restorative Neurostimulation in the U.S., Europe and Australia, additional post-market clinical studies and research, and general operations.

The financing was led by new investor Gilde Healthcare and joined by new investor, Viking Global Investors. Key existing investors who participated in the financing include Ally Bridge Group, Sofinnova Partners (Crossover Fund), Fountain Healthcare Partners, and Perceptive Advisors.

“A financing of this magnitude will allow us to accelerate our efforts to revolutionize the treatment of mechanical low back pain through ReActiv8 Restorative Neurostimulation, including by continuing our rapid commercial growth and building on our insurance coverage for ReActiv8,” said Jason Hannon, CEO of Mainstay Medical. “We are now strongly capitalized to execute on our corporate objectives.  In addition to commercial expansion in our target markets, these objectives include the generation of additional clinical and health economic data to further demonstrate that ReActiv8’s purpose-built, restorative approach to the treatment of mechanical chronic low back pain is superior to competitive therapies originally designed for other indications, as well as the continued development and enforcement of our dominant intellectual property portfolio.”

“We are excited to lead this financing and to work with Mainstay to continue to unlock the potential of ReActiv8 therapy,” said Geoff Pardo, Partner at Gilde Healthcare, who also joins the Mainstay Medical Board of Directors. “Patients with mechanical chronic low back pain have had very limited treatment options, and the restorative mechanism of action offered by ReActiv8 is both unique and very promising.”
