Unipolar Depression | Unmet Need | Treatment Resistant Depression | US/EU | 2020

Numerous antidepressant therapies are available to treat major depressive disorder (MDD), many of which have long been generic and are entrenched in medical practice. However, most current therapies suffer from shortcomings in efficacy and/or safety and tolerability, resulting in inadequate patient response and remission rates and creating opportunities for new, improved therapies for treatment-resistant depression (TRD). Although newer-to-market agents such as Lundbeck / Takeda’s Trintellix / Brintellix (vortioxetine) and Janssen’s Spravato (esketamine) have expanded the armamentarium of therapeutic options and, in the case of Spravato, provided a novel, fast-acting option, unmet need remains for new therapies. This report provides quantitative insight into psychiatrists’ perceptions of key treatment drivers and goals and assesses the current level of unmet need and opportunity in the treatment of TRD.


  • What are the treatment drivers and goals for TRD?
  • What are surveyed psychiatrists’ opinions of the relative performance of select therapies, including Trintellix / Brintellix (Lundbeck / Takeda), Spravato (Janssen), and aripiprazole (Otsuka Pharmaceutical’s Abilify, generics) on key efficacy, safety / tolerability, and convenience of administration attributes?
  • What drug attributes are key influencers, which have limited impact, and which are hidden opportunities?
  • What trade-offs across different clinical attributes and prices are acceptable to U.S. and European psychiatrists for a hypothetical new drug to treat TRD?


Unmet Need supports clinical development decisions by identifying key attributes and assessing areas of unmet need for a specific disease or subpopulation. Based on surveys with U.S. and European physicians, this report provides insight into key treatment drivers and goals, the performance of current therapies, and the remaining commercial opportunities. One market scenario is profiled in detail by DRG experts, and additional customized market scenarios can be evaluated with the corresponding TPP simulator.
