Understanding Treatment-Resistant Depression (TRD)

Treatment-Resistant Depression (TRD) is a subset of major depressive disorder (MDD) where patients do not respond adequately to at least two different antidepressant treatments of appropriate dose and duration. According to Johns Hopkins Medicine, approximately 30% of individuals with MDD experience TRD, with young adults and late teens being particularly susceptible. This high prevalence underscores the urgent need for alternative and more effective therapeutic options.

Market Size and Share

The global TRD market is experiencing significant growth due to increasing awareness and the pressing need for effective treatments. In 2024, the market was valued at approximately USD 3.5 billion and is projected to reach USD 6.7 billion by 2035, growing at a CAGR of 6.11% during the forecast period of 2025-2035 . North America holds the largest market share, attributed to advanced healthcare infrastructure and a high prevalence of depression check out Expert Market Research's Treatment-Resistant Depression Drug Pipeline Analysis report.
