Latuda Adjunctive Therapy for MDD Phase 3 IND Approved, Expansion of Indication Expected


  • BUKWANG PHARMACEUTICAL confirmed on June 2, 2026 that the MFDS approved its Phase 3 IND for Latuda (lurasidone) as adjunctive therapy for Major Depressive Disorder (MDD).
  • The trial enrolls 364 adult patients with inadequate response to existing antidepressants, randomized to daily lurasidone (20/40/60mg) or placebo for 8 weeks in a double-blind, multicenter design.
  • Primary endpoint: change in MADRS score from baseline; secondary endpoints: safety and tolerability. Estimated duration ~24 months (may extend based on enrollment rate).
  • Latuda, approved as a new drug in 2023, aims to expand its label to include MDD adjunctive therapy, offering more treatment options.
  • Per the disclosure, the statistical probability of final drug approval is approximately 10%. Failure may lead to changes or abandonment of commercialization plans, as warned.
  • [AI Summary]The Phase 3 IND approval for Latuda's MDD indication is a positive step for long-term growth, but given the low success probability (≈10%) and lengthy trial period (>2 years), the stock's upside may be limited to short-term momentum, requiring cautious investment risk assessment.
