Viatris Announces Positive Top-Line Results from Second Pivotal Phase 3 VEGA-3 Trial of MR-141 in Presbyopia

MR-141 Met Primary And All Secondary Endpoints, Demonstrating Rapid And Sustained Improvement In Near Visual Acuity Without Compromising Distance Vision Safety Profile Consistent With Previous Clinical Trials And No Treatment-Related Serious Adverse Events Reported In This Study Targeting Application To U.S. FDA In Second Half of 2025 , /PRNewswire/ -- Viatris Inc. (Nasdaq: VTRS), a global healthcare company, today announced positive top-line results from VEGA-3, the second pivotal Phase 3 trial evaluating MR-141 (phentolamine ophthalmic solution 0.75%) in treating presbyopia. Presbyopia is the progressive loss of the ability to focus on close objects that results in blurred near vision and eye strain, particularly in dim lighting conditions. The VEGA-3 Phase 3 trial is a randomized, placebo-controlled, double-blind study, with a total of 545 patients who were randomized 3:2 to receive either MR-141 or placebo, once daily in the evening. In summary: Significantly more patients treated in the MR-141 arm achieved the primary endpoint of Early Treatment Diabetic Retinopathy Study (ETDRS) (≥3-line) gain in binocular distance-corrected near visual acuity (DCNVA) and with less than 5 letters of loss in binocular best-corrected distance visual acuity (BCDVA) from baseline at 12 hours post-dose on Day 8, compared to placebo (p<0.0001). Significantly more patients treated in the MR-141 arm achieved ≥15-letters ETDRS (≥3-line) gain in DCNVA and with less than 5 letters of loss in BCDVA at 1-hour post-dose on Day 1 compared to those receiving placebo (p=0.0002). Significant patient-reported functional benefit at Days 3, 8, and Week 6 were observed with patients reporting satisfaction with near vision upon awakening (p<0.0001) and satisfaction with their improvement in near vision (p<0.0001). Patient reported significant improvement in near vision in dim/low light at Days 3, 8 and Week 6 compared with placebo (p<0.0001). No evidence of tachyphylaxis was observed during 6-week follow up. MR-141 demonstrated a safety profile consistent with previous trials, with no new safety signal identified and no treatment-related serious adverse events reported in this study. The most common (≥5%) treatment-emergent adverse events included conjunctival hyperemia, instillation site irritation, and dysgeusia and were predominantly mild. Low rate of headache (2.6%) was reported over the study period. Viatris Chief R&D Officer Philippe Martin said, "Presbyopia is a very common condition affecting approximately 90 percent of adults in the U.S. over the age of 45, who often experience blurred near vision and eye strain. We are pleased with the positive results from the second pivotal Phase 3 trial, which reinforce our confidence in MR-141 and its benefit-risk profile as a potential, non-invasive option to support the millions of patients impacted by this condition." VEGA-3 patients will continue to be monitored for long-term safety over 48 weeks. For more information on the VEGA-3 study design, refer to ClinicalTrials.gov (NCT06542497).

It is a nearly universal condition that, when uncorrected, contributes significantly to vision-related disability. Presbyopia leads to symptoms like eye strain and blurred near vision, impacting daily tasks and productivity. The condition is associated with reduced quality of life, functional independence, and work efficiency. It affects nearly 128 million people in the United States—about 90% of adults over 45. By age 50, most Americans require some form of near-vision correction, such as reading glasses or multifocal lenses. Globally, an estimated 1.8 billion people were presbyopic in 2015, projected to rise to 2.1 billion by 2030. With global productivity losses estimated at $11–25 billion due to uncorrected cases, there is significant economic consequences from lost productivity and increased healthcare utilization. Timely access to affordable near-vision correction is essential to reducing its impact. About ViatrisViatris Inc.
