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.
