Addresses a Significant Unmet Need in Japan as First and Only Approved Treatment Option for GAD

PITTSBURGH, March 23, 2026 /PRNewswire/ -- Viatris Inc. (Nasdaq: VTRS), a global healthcare company, today announced that Japan's Ministry of Health, Labour and Welfare (MHLW) has approved Effexor^® SR 37.5 mg / 75 mg capsules (venlafaxine hydrochloride), a serotonin-noradrenaline reuptake inhibitor (SNRI), for the treatment of adults with generalized anxiety disorder (GAD). Following the MHLW's decision, Effexor^® becomes the first and only approved treatment option in Japan for adults living with GAD, addressing a long-standing unmet medical need in mental health and enabling new access to care. Effexor^® is currently approved in Japan for the indication of major depressive disorder in adults, and with this approval, is now available to patients with GAD.

GAD is among the most prevalent and highly disabling mental health conditions, negatively impacting patients' quality of life and disrupting activities of daily living. A recent study reported the prevalence of probable GAD in Japan as 7.6% of the general population.¹

"The approval of Effexor^® in Japan for generalized anxiety disorder demonstrates the successful execution of our strategy to advance a differentiated and increasingly innovative portfolio in Japan, bringing forward value-added therapies that address a significant unmet need," said Philippe Martin, Viatris Chief R&D Officer. "This approval also reflects our ability to effectively implement an optimized lifecycle strategy for our established brands and to leverage our deep local expertise."

"This approval marks the introduction of a new treatment option for adults in Japan living with GAD," said Corinne Le Goff, Viatris Chief Commercial Officer. "We look forward to leveraging our strong infrastructure and deep expertise in central nervous system therapies in Japan to bring access to this much needed treatment to patients."

The approval of Effexor^® for GAD is based on a Phase 3 placebo-controlled, randomized, double-blind, multicenter study of venlafaxine in patients with GAD conducted in Japan (Study B2411367), which 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. 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).

These results and the results of a long-term extension study of venlafaxine in Japanese outpatients with GAD were included as part of the applications for approval. Effexor^® is currently approved to treat GAD in more than 80 countries outside of Japan.

About Generalized Anxiety Disorder (GAD) 
Generalized Anxiety Disorder (GAD) is a mental health disorder whose central symptom is chronic and uncontrollable "anxiety" or "worry" about everyday life events or activities. Other symptoms include difficulty to get enough sleep, muscle tension/stiffness, feeling restless, irritable, or finding it difficult to concentrate, which may cause impairment in social, occupational, or other areas of functioning. In Japan, the World Health Organization reports that 2.6% of the population will suffer from GAD in their lifetime. A recent study in Japan reported the prevalence of probable GAD is 7.6%¹, suggesting that this condition may be significantly underdiagnosed.
