Takeda Pharmaceutical Company Limited (TSE:4502) has launched ORZEYFUL (oveporexton) in Japan and China. The simultaneous rollout gives physicians in both countries their first opportunity to prescribe the new treatment to patients diagnosed with narcolepsy type 1.

ORZEYFUL is a first-in-class OX2R agonist that targets the underlying mechanism of narcolepsy type 1 rather than addressing symptoms alone. In Phase 3 clinical trials, the therapy demonstrated broad symptom gains compared to placebo, along with a generally well-tolerated safety profile. The launch advances the company's orexin franchise into commercial distribution across two major Asian markets. Following the news, shares of Takeda rose 2.77% to 6,052 JPY.

Investors and market observers will be watching early prescription adoption by specialists, reimbursement developments in both regions, and potential future label expansions or regulatory submissions in the United States and Europe.
