Viatris Announces Positive Top-line Results from Phase 3 Study of EFFEXOR® in Japanese Adults with Generalized Anxiety Disorder (GAD)
VTRS 10.09.2024

Treatment with once-daily EFFEXOR®met primary and all secondary efficacy endpoints in outpatient adults with GAD
EFFEXOR®was generally well tolerated, consistent with its known safety profile
The study achieved its primary objective of superiority of anxiolytic effects of venlafaxine compared to placebo at 8 weeks, based on the change in the Hamilton Anxiety Rating Scale (HAM-A) total score from baseline (two-sided p-value=0.012). All seven secondary efficacy endpoints as defined by the trial protocol were met, which confirmed superiority compared to placebo.
In this study, EFFEXOR®was generally well tolerated with a profile consistent with its known safety profile in non-Japanese patients. In particular:
- Low discontinuation rates due to treatment emergent adverse events (TEAEs) were seen (7.3% vs 1.7% in placebo) with 3.9% vs 0.6% assessed as related to treatment.
- No serious TEAEs or TEAEs with severe intensity were observed (0% vs 1.1% and 0.6%, respectively, in placebo).
- Incidence of new suicidal ideation was lower in the EFFEXOR®treatment group than in placebo (2.8% vs 5.1%).
- Commonly observed TEAEs like nausea and somnolence were reported at a lower rate than outside of
Japan .
"We are very pleased with these top-line results, which consistently demonstrate the efficacy and safety of EFFEXOR®for the treatment of generalized anxiety disorder in Japanese patients with moderate to severe disease. The benefit-risk profile observed with EFFEXOR®in this study underscores its potential as a meaningful treatment option for patients with GAD in
"Despite generalized anxiety disorder being well-recognized globally, there is a large, general public awareness gap of GAD in

About Phase 3 Study B2411367The study was a randomized, double-blind, placebo-controlled, multicenter Phase 3 study that was conducted in
Patients were randomized equally to a flexible dose of 75-225 mg/day venlafaxine or placebo (once-daily, oral dosing) for an 8-week treatment period. The primary objective of the study was to show superiority over placebo in terms of the anxiolytic effects of venlafaxine, based on the change in the HAM-A total score from baseline at 8 weeks. The secondary objective was to evaluate the safety and tolerability of venlafaxine.
Key secondary endpoints were defined as absolute score/change from baseline at 8 weeks in:
- HAM-A psychic anxiety factor
- HAM-A somatic anxiety factor
- Clinical Global Impressions-Severity of Illness (CGI-S)
- Clinical Global Impressions-Global Improvement (CGI-I)
- Generalized Anxiety Disorder 7 (GAD-7)
- Zung Self-Rating Anxiety Scale (ZSRAS)
- Sheehan Disability Scale (SDISS)
