Objective: Although the safety and efficacy of desvenlafaxine have been demonstrated, long-term evidence in Asians is lacking. We examined the safety and effectiveness of desvenlafaxine for up to 6 months in routine clinical practice in Korea.
Methods: This multicenter, open-label, prospective observational study was conducted from February 2014 to February 2020 as a postmarketing surveillance study of desvenlafaxine (ClinicalTrials.gov identifier: NCT02548949). Adult patients with major depressive disorder (MDD) were observed from the initiation of treatment for 8 weeks (acute treatment phase) and then up to 6 months (continuation treatment phase) in a subsample. Safety was evaluated by incidence of adverse events (AE) and adverse drug reactions. Treatment response was assessed using the Clinical Global Impression- Improvement (CGI-I) scale.
Results: We included 700 and 236 study subjects in the analysis of acute and continuation treatment phase, respectively. In acute treatment phase, AE incidence was 9.86%, with nausea being most common (2.00%). In continuation treatment phase, AE incidence was 2.97%, with tremor occurring most frequently. After acute treatment (n = 464), the treatment response rate according to the CGI-I score at week 8 was 28.9%. In long-term users (n = 213), the response rate at month 6 was 45.5%. During the study period, no clinically relevant changes in BP were found regardless of concomitant use of antihypertensive drugs.
Conclusion: This study provides evidence on the safety and effectiveness of desvenlafaxine in adults with MDD, with a low incidence of AE, consistent AE profile with previous studies, and improved response after long-term treatment.
