The unipolar depression market is crowded and highly genericized. The prominent use of SSRIs and, to a lesser extent, SNRIs as early-line treatments contributes to the challenges branded therapies face when entering this market. Newer-to-market brands (e.g., Lundbeck / Takeda’s Trintellix / Brintellix, Lundbeck / Otsuka Pharmaceutical’s Rexulti / Rxulti) largely compete for use in treatment-resistant depression (TRD) patients, who make up one-third of the major depressive disorder population. The most recent entrant to the depression market, Janssen’s Spravato, offers the fastest onset of therapeutic effect among the approved therapies—fulfilling a key unmet need—but its use for TRD is constrained by multiple factors. Because of remaining unmet need, physicians will continue to look to emerging therapies—many of which offer novel mechanisms of action—as potential future treatment options in this market.

QUESTIONS ANSWERED:

  • What factors drive and constrain the use of branded antidepressants and atypical antipsychotics? What branded therapy is expected to experience the greatest commercial success during the forecast period?
  • What clinical role will Spravato (Janssen’s esketamine) play in the treatment of TRD?
  • Given the crowded, highly genericized unipolar depression market, what is the commercial potential of key emerging therapies for unipolar depression?
  • What are the greatest areas of unmet need in the treatment of unipolar depression and how are late-phase emerging therapies expected to address these unmet needs?
