ResMed dreams bigger with latest acquisition deal

Australian-founded Resmed has completed its $US360 million acquisition of Noctrix Health, a medical device company developing clinically validated wearable therapeutics for chronic neurological disorders.
The acquisition expands Resmed’s clinical sleep health portfolio into an adjacent area of significant unmet need, including the treatment of Restless Legs Syndrome (RLS) which is the third most prevalent sleep disorder. It adds to Resmed’s wide-ranging offerings, which include its respiratory therapies for obstructive sleep apnea (OSA) and digital platforms.
“Our acquisition of Noctrix Health marks an important step forward in advancing our 2030 strategy and expanding our clinical sleep health portfolio,” said Mick Farrell, Chairman and CEO of Resmed. “We are excited to welcome the Noctrix team to Resmed and scale solutions that improve lives through better sleep and home health technologies.”
Noctrix’s Nidra Tonic Motor Activation (TOMAC) Therapy is an FDA De Novo classified, non-invasive, non-pharmacologic treatment designed to reduce symptoms of moderate-to-severe RLS and improve sleep quality in adults who have not found sufficient relief with drug therapy. For many patients, this therapy can deliver meaningful improvement in daily life and overall sleep health.
Their legs will pivot and kick, and it’s very bad for the bed partner, obviously,” Farrell said. “It can be treated by drugs, but they have awful side effects, so many people don’t; they just go without treatment, and have this awful thing all their lives.”
Noctrix has rapidly built a strong foundation of clinical validation for its breakthrough therapy, including 10 peer-reviewed publications and inclusion in the American Academy of Sleep Medicine (AASM) clinical practice guidelines for the treatment of RLS, notable achievements that reflect both scientific validation and growing clinical adoption.
Resmed plans to integrate Noctrix’s technology into its portfolio of connected devices and digital health solutions to help expand access, improve care pathways and enhance patient outcomes over time.
“Since founding Noctrix, our mission has been to deliver innovative, non-pharmacologic solutions for people living with RLS who have limited treatment options,” said Shri Raghunathan, President and CEO of Noctrix Health. “Joining Resmed will help us advance that mission, enabling us to expand access to TOMAC therapy and reach more patients with a clinically validated solution that can help meaningfully improve sleep and quality of life.”
