The company also initiated its global Phase 3 HARMONIA trial and said enrollment in a registrational expansion cohort remains on track.<br/><br/>The firm ended the quarter with a sizable $972.2 million cash position, which management says should fund operations into the first quarter of 2028. Meanwhile, net losses widened slightly to $120.9 million.<br/><br/>For long-term investors, the key question going forward is whether Dyne can successfully transition from promising clinical data to commercial execution. The pipeline looks increasingly credible, but expectations are now much higher too.</p><h2>Should you buy stock in Dyne Therapeutics right now?</h2>
