Patent Cliff Analysis

The projected revenue decline for Ozempic follows a structured trajectory, beginning with gradual exposure and culminating in accelerated erosion post-2030. In the near term, specifically 2025, the revenue impact remains minimal, estimated at a range of 0-2%. This limited impact is attributed to the absence of biosimilars in the market, with competitive pressure primarily stemming from the newer GLP-1 class drugs, rather than any direct biosimilar competition.

As the timeline progresses into 2026-2027, the revenue loss is expected to be more pronounced. This period marks the onset of localized patent expirations in key emerging markets such as China, Brazil, India, and Canada, which are projected to result in a 5-8% share loss. This decline aligns with an estimated revenue impact of USD 1.1-1.9 billion, consistent with the anticipated losses depicted in the accompanying chart. The erosion during this phase is driven by the gradual introduction of generic alternatives and local competitors, following the expiration of patents in these regions. 

In 2028-2029, share loss is expected to rise to 12-18%, driven by several factors including payer renegotiations in established markets and the preparation of tenders in Europe. Additionally, a growing presence of generics in the Asia-Pacific (APAC) and Latin American (LATAM) regions will contribute to this increase. This period of heightened competition and erosion of market share aligns with the mid-range increase depicted in the graph. The intensified competitive landscape, combined with regional price adjustments and cost-cutting measures, is likely to push sales further downward.

The most significant revenue loss for Ozempic is anticipated between 2030 and 2032, a period where the rate of share erosion accelerates sharply to 25-50%. This steep decline is largely driven by the expiration of exclusivity in major markets such as the European Union and Japan, as well as the impending U.S. patent cliff. The loss of exclusivity in these regions will trigger a rapid shift toward biosimilars and generic alternatives, further intensifying the competitive pressure. The chart reflects this accelerated loss, with both the expected decline in market share and the sales at risk growing significantly during this phase. 

By 2033, the global share loss is expected to stabilize at 55-60%, which reflects the mature penetration of biosimilars in key markets and the eventual plateau in the erosion of sales. This phase marks the maturation of the biosimilar market, where competition becomes more established, and the impact of additional generic products is already embedded in the market structure. The overall trend demonstrates a clear, systematic erosion of market share for Ozempic, largely driven by the expiration of patents, the rise of generics, and the increasing market penetration of alternative therapies.

Current Market Scenarios 

Semaglutide (Ozempic), currently protected by patents, grants Novo Nordisk market exclusivity in major regions, but this will change as the patent expiration approaches. The dynamics of the market will shift significantly with new entrants and competitors preparing for biosimilar and generic launches. 

In the United States and the European Union, the primary patent expiration is expected in the early 2030s. This will open the market to alternative treatments, with competitors preparing to launch biosimilars and generics. The pace of these market entries will be influenced by the regulatory approval process, which can differ by region. The approval of biosimilars and generics will alter market share and pricing, directly affecting Novo Nordisk's position. Regulatory hurdles could delay some entrants, but eventual competition will pressure prices and erode exclusivity. 

In Canada, China, and India, the patent expiration timeline is expected to be earlier, potentially allowing competitors to gain market access sooner. In China, ongoing legal challenges to patents may fast-track the availability of competing treatments, making it a key market for early generic entries. Similarly, India’s regulatory landscape will influence the speed at which competitors can launch products, increasing competition in a price-sensitive market.

Other factors such as global demand for GLP-1 receptor agonists and increasing adoption of diabetes and obesity treatments will continue to drive market growth. However, the rise of biosimilars and generics will challenge pricing and profit margins. Moreover, emerging markets with increasing healthcare access present growth opportunities, but they also bring additional competitive pressures as patents expire. 

Market Dynamics

Growing Demand for Comprehensive Diabetes Solutions

The market for semaglutide (Ozempic) is strongly driven by the increasing global prevalence of type 2 diabetes, which is rapidly becoming a major public health concern. Recent studies indicate that more than 460 million adults worldwide are affected by diabetes, a condition that is directly contributing to the rising demand for effective treatments like semaglutide. The dual-action mechanism of GLP-1 receptor agonists like semaglutide makes it a highly sought-after treatment, providing a comprehensive solution for patients struggling with blood sugar management. 

As healthcare systems increasingly emphasize patient outcomes and treatment efficacy, therapies that offer robust solutions for managing type 2 diabetes are gaining traction. Semaglutide's proven ability to effectively manage blood sugar levels will continue to drive its adoption, even as competitive pressures from biosimilars and generics increase post-patent expiration. Furthermore, regions such as the U.S. and the EU, where regulatory processes for biosimilars and generics tend to be more stringent, may face delays in the approval of competing products. This could provide a temporary extension of market exclusivity for the branded semaglutide product, further supporting its continued market leadership in the near term. 

The Pressure of Pricing and Market Erosion Post-Patent

The expiration of the semaglutide patent will lead to increased competition in the form of biosimilars and generics, significantly affecting the pricing dynamics and market share distribution. In the post-patent environment, the market will likely experience downward pricing pressure, especially in price-sensitive regions where healthcare systems prioritize cost-effective solutions. As new entrants emerge with lower-cost alternatives, there will be an erosion of Novo Nordisk’s market share, as patients and healthcare providers opt for more affordable options. Additionally, the regulatory approval process in different markets will impact the timing and speed at which competitors enter the market. For example, in markets like the U.S. and EU, the approval timelines for biosimilars could delay the market penetration of these alternatives, although they will eventually intensify competition. In contrast, in regions like Canada, India, and China, biosimilars and generics are likely to enter the market much sooner, exerting downward pressure on pricing and leading to faster shifts in market dynamics. The entry of biosimilars will also raise concerns regarding clinical efficacy, as healthcare providers may be cautious about switching patients to alternatives based solely on price, especially in a therapeutic area where patient outcomes are critical.

“Innovating Beyond the Patent - Unlocking Future Growth Paths”

Despite the inevitable competition post-patent expiration, the market will present several growth opportunities. One of the most significant opportunities lies in the development of next-generation formulations of semaglutide. These could include longer-acting formulations, such as monthly injections or extended-release versions, which could cater to patients who prefer less frequent dosing. Combination therapies that target multiple aspects of metabolic disorders, such as cardiovascular disease, could also offer a differentiated market position. This type of innovation can help maintain the relevance of the original branded product in the market despite increasing competition. In addition, the continued rise of biosimilars presents an opportunity to increase market access, particularly in emerging markets where affordability has been a barrier to treatment. As healthcare systems in these regions become more accessible and capable of absorbing new treatments, the availability of affordable alternatives will allow more patients to benefit from therapies like semaglutide. Another opportunity lies in expanding into emerging markets where diabetes and obesity are rising rapidly. Countries in Asia, Latin America, and Africa are experiencing a surge in these conditions, and as healthcare infrastructure improves, there will be a greater push for effective treatment options.

Case Study (Recent Engagement): Keytruda Patent-Cliff & Price-Erosion Impact Model

PROJECT OBJECTIVE

To evaluate the potential revenue, price, and patient access implications of Keytruda’s 2028 patent cliff, incorporating biosimilar entry dynamics, country-specific adoption curves, and Merck’s lifecycle defense strategies (remarkably the subcutaneous formulation). The goal was to provide the client with a transparent, scenario-based model to anticipate outcomes and inform strategy.

GVR SOLUTION

• Built a bottom-up commodity-flow and analogue-based model, anchored on Merck’s $29.5B Keytruda sales in 2024.

• Integrated jurisdictional LOE timelines (EU mid-2028, U.S. 2028-2029 pending litigation outcomes).

• Modeled biosimilar adoption S-curves calibrated to oncology antibody analogues (EU faster via tenders, U.S. slower via contracting).

• Applied price-erosion benchmarks (EU -15-30% Yr-1, deepening to -45-60% by Yr-3; U.S. -10-25% net decline over same horizon).

• Layered lifecycle defenses (SC uptake assumptions of 25-40% of innovator units, combo refresh, contracting) to quantify buffers.

• Delivered outputs as a dynamic Excel scenario tool and a management-ready PPT deck with revenue bridges, sensitivity tornadoes, and SC migration visuals.

IMPACT FOR CLIENT

• Enabled the client to quantify downside vs. defense-optimized revenue trajectories:

  • Base case: 30-40% global revenue decline by Year-3 post-LOE.

  • Downside: 45-55% decline in tender-heavy markets.

  • Defense-optimized: Contained erosion to ~-20-25% with strong SC adoption.

• Gave the client a clear view of which markets drive early erosion (EU) and where strategic contracting or SC migration can preserve share (U.S.).

• Equipped decision-makers with a playbook of watch-points (tender concentration, litigation outcomes, SC IP coverage, combo pipeline) to guide commercial strategy.

• Provided a transparent methodology that could be presented to boards/investors with evidence-backed assumptions

WHY THIS MATTERS

• Keytruda is the world’s best-selling cancer drug, representing nearly one-third of Merck’s revenue.

• Patent expiry will reshape both Merck’s earnings profile and global oncology access dynamics.

• Payers and governments stand to benefit from biosimilar entry through lower costs, but manufacturers need to manage cliff risk while capturing upside from lifecycle innovations.

• Understanding how quickly revenues erode and how patient access expands post-biosimilar is critical for:

  • Biopharma companies (strategic planning, pipeline prioritization).

  • Investors (valuing Merck’s cash flows beyond 2028).

  • Payers and policymakers (budgeting for oncology drug spend).

• A robust patent cliff model helps clients navigate the dual challenge of price erosion and patient expansion, ensuring strategies are grounded in real-world benchmarks.
