Resmed Corp. has agreed to acquire Noctrix Health Inc. for $340 million, boosting its sleep health portfolio. Noctrix has developed Nidra, a wearable neuromodulation device which treats restless legs syndrome (RLS) without disrupting sleep. With RLS impacting approximately 7% of adults globally, including about 17 million people in the U.S., the technology offers a non-drug option that could potentially treat a significant proportion of this patient population.
