Sosei Group ( (JP:4565) ) has provided an update.
Nxera Pharma reported positive top-line results from a Phase 3 trial in South Korea of its insomnia drug daridorexant 50 mg, showing statistically significant improvements over placebo in subjective total sleep time, time to fall asleep and wake after sleep onset, with a safety profile comparable to placebo. With insomnia affecting an estimated 6.5–11 million adults in South Korea and current treatment needs remaining high, the data clear a key regulatory hurdle and position Nxera to file for marketing authorization in early 2026 and potentially launch in 2027, extending the global footprint of QUVIVIQ and strengthening the company’s competitive position in the rapidly evolving insomnia treatment market.
The most recent analyst rating on (JP:4565) stock is a Hold with a Yen720.00 price target. To see the full list of analyst forecasts on Sosei Group stock, see the JP:4565 Stock Forecast page.
