Viatris Provides Pipeline Update on Four Regulatory Milestones

• Receives U.S. Food and Drug Administration (FDA) Approval for Generic Version of Sandostatin^® LAR Depot (Octreotide Acetate for Injectable Suspension)
• U.S. FDA Accepts New Drug Application for Low Dose Estrogen Weekly Patch for Contraception
• U.S. FDA Clears Investigational New Drug Application for MR-146 in Neurotrophic Keratopathy
• Japan Pharmaceuticals and Medical Devices Agency Accepts Japanese New Drug Application Filing for Pitolisant in Obstructive Sleep Apnea Syndrome

PITTSBURGH, Dec. 18, 2025 /PRNewswire/ -- Viatris Inc. (Nasdaq: VTRS), a global healthcare company, today announced four recent regulatory milestones spanning across all stages of its global pipeline:

• Octreotide Acetate for Injectable Suspension: The U.S. Food and Drug Administration (FDA) has approved the Company's octreotide acetate for injectable suspension, a generic version of Sandostatin^® LAR Depot. The therapy is indicated for treatment in patients who have responded to and tolerated Sandostatin Injection subcutaneous injection for acromegaly, severe diarrhea/flushing episodes associated with metastatic carcinoid tumors, and profuse watery diarrhea associated with Vasoactive Intestinal Peptide secreting tumors.
• Low Dose Estrogen Weekly Patch: The U.S. FDA has accepted for review the New Drug Application (NDA) for the Company's investigational low dose estrogen weekly patch (150 mcg norelgestromin and 17.5 mcg ethinyl estradiol) for contraception. The NDA is accepted under the FDA's 505(b)(2) regulatory pathway, and the FDA has assigned a target action date (PDUFA) of July 30, 2026.
• MR-146: The U.S. FDA has cleared the Company's Investigational New Drug (IND) application for MR-146, an Enriched Tear Film^TM (ETF) Adeno-Associated Virus (AAV) gene therapy candidate targeted to treat people with neurotrophic keratopathy (NK). The Company plans to initiate a Phase 1 / 2 clinical trial, CORVITA, for MR-146 in patients with NK in the first half of 2026.
• Pitolisant: The Japan Pharmaceuticals and Medical Devices Agency (PMDA) has accepted the Company's Japanese New Drug Application (J-NDA) for pitolisant in obstructive sleep apnea syndrome (OSAS). The Company remains on track to submit a J-NDA for narcolepsy by the end of the year.

"We are proud of these recent regulatory achievements, which culminate a year of significant R&D advancement in 2025," said Viatris Chief R&D Officer Philippe Martin. "These important milestones not only demonstrate the strength of our scientific and regulatory capabilities, but also our dedication to addressing areas of significant unmet medical need for patients. We look forward to continuing to work closely with health authorities around the world as we progress our pipeline in 2026 and beyond." 

About Octreotide Acetate for Injectable Suspension
Octreotide acetate for injectable suspension is a long-acting medication used to help manage the symptoms of certain rare conditions, including acromegaly (a disorder in adults that causes abnormal growth of bones, organs and tissues) and complications associated with specific cancerous tumors. It is the Company's first approved injectable using microsphere technology.

This approval marks the Company's fourth injectable FDA approval in 2025 – joining iron sucrose, paclitaxel and liposomal amphotericin B – underscoring the Company's ability to successfully navigate complex regulatory pathways and strategy to expand its generics portfolio with technically complex, high-value products.

About Low Dose Estrogen Weekly Patch for Contraception
The investigational treatment is a once-weekly transdermal contraceptive patch being developed for women of childbearing potential with a BMI below 30 kg/m² who are appropriate candidates for combined hormonal contraception and who prefer a non-invasive, reversible option with a lower estrogen dose. The patch delivers approximately 150 mcg of norelgestromin and 17.5 mcg of ethinyl estradiol per day and is applied once weekly for three weeks, followed by a one-week patch-free period.

The planned 505(b)(2) NDA is supported by results from the Phase 3 Luminous Study, which demonstrated a favorable efficacy and safety profile and strong patch adhesion performance.

The patch represents the potential to meet an important unmet medical need for women seeking alternatives to regular estrogen dose and long-acting contraception treatments. This investigational treatment option builds upon the Company's established capability in transdermal drug delivery and represents a lifecycle advancement of the contraceptive patch Xulane^® (norelgestromin and ethinyl estradiol transdermal system) 150/35 mcg per day.

About MR-146 for Neurotrophic Keratopathy
NK is a rare but potentially sight-threatening corneal disease, which impacts approximately 73,000 people in the United States. It is a degenerative disease that causes progressive damage to the cornea. The most common causes of the disease are viral infections (herpes simplex, varicella zoster [shingles]), diabetes, multiple sclerosis, chemical burns, dry eye disease and corneal surgeries.

MR-146 utilizes an ETF^TM AAV gene therapy platform, a first-of-its-kind approach designed to be delivered directly to the lacrimal gland via a single injection, using non-replicating DNA delivery transporters for the production and delivery of human Nerve Growth Factor (hNGF) protein to the cornea via tears. NK is the first indication of many that could be treated with this platform.

About Pitolisant
Pitolisant is a selective histamine H3 receptor antagonist/inverse agonist that modulates the brain's sleep–wake pathways.

The J-NDA application is supported by positive Phase 3 data in Japanese patients. The Phase 3 trial evaluated the effect of pitolisant in Japanese patients with OSAS who were experiencing residual Excessive Daytime Sleepiness (EDS) despite treatment with CPAP therapy. At the end of the 12-week treatment period, patients receiving pitolisant scored lower on the Epworth Sleepiness Scale used to measure EDS compared to those in the placebo group, and this difference was statistically significant (p=0.007). Additionally, safety and tolerability were consistent with results from global clinical studies.
