Detailed Narrative
Pipeline Expansion and Diversification
Merck is actively expanding and advancing its research program, currently conducting over 80 Phase III studies across various therapeutic areas. The company highlights over 20 new and potential future growth drivers, including recent successful launches like WINREVAIR and CAPVAXIVE. Novel late-phase compounds such as enlicitide, tulisokibart, sac-TMT, and MK-3000 are expected to drive significant scientific and commercial opportunities, reinforcing confidence in the company's ability to grow beyond the KEYTRUDA LOE period.
New Product Launch Momentum
WINREVAIR, for pulmonary arterial hypertension, achieved over $1 billion in cumulative net sales within 15 months of launch, demonstrating strong patient impact and commercial execution. CAPVAXIVE, a pneumococcal vaccine, generated $129 million in sales, driven by demand from retail pharmacies and non-retail customers. ENFLONSIA, a monoclonal antibody for RSV prevention in infants, recently received FDA approval and ACIP recommendation, with orders already being taken, positioning it for a successful launch ahead of the upcoming RSV season.
Strategic Portfolio Optimization and Reinvestment
Merck announced a multiyear optimization initiative to redirect $3 billion of cost savings from lower-growth areas of the business to higher-potential areas. This program aims to enhance productivity and streamline operations, allowing for full reinvestment into the robust early- and late-phase pipeline and key growth drivers. The company expects overall investment to continue increasing, reflecting compelling opportunities and a commitment to long-term innovation-driven growth.
Cardiopulmonary and Cardiometabolic Pipeline Progress
The acquisition of Verona Pharma, expected to close in Q4, brings Ohtuvayre, a novel first-in-class treatment for COPD, complementing Merck's growing cardiopulmonary program. Positive top-line results were announced for enlicitide, an oral PCSK9 inhibitor, from two Phase III trials (CORALreef heterozygous familial hypercholesterolemia and CORALreef AddOn), showing statistically significant and clinically meaningful reductions in LDL-cholesterol. Enrollment for the Phase III CORALreef Outcomes trial is complete, with detailed findings to be presented at future medical meetings.
Oncology Leadership and Pipeline Beyond KEYTRUDA
KEYTRUDA continues to expand its indications, with a recent FDA approval for its 42nd indication and 10th earlier-stage approval in head and neck squamous cell carcinoma. The broader oncology pipeline includes advancements in tissue targeting with three Phase III trials for ifinatamab deruxtecan through the Daiichi Sankyo collaboration. Positive progression-free survival and overall survival results were also announced for KEYTRUDA plus chemotherapy in ovarian cancer, marking a significant milestone for immune checkpoint inhibitors in this setting.
GARDASIL China and Japan Headwinds
GARDASIL sales were significantly impacted by a 55% decrease, primarily due to a $1.3 billion decline in China. Elevated channel inventories and soft demand mean shipments to China will not resume through at least the end of 2025. Additionally, Japan is expected to be a more significant headwind in the second half of 2025 as the company laps the increased vaccinations from the 2024 catch-up📎 cohort. Despite these challenges, Merck expects full-year growth for GARDASIL excluding China.
