EU JCA and US MFN collision: The next global pricing and market access risk frontier
When the European Union (EU) adopted the Joint Clinical Assessment (JCA) as the cornerstone of its Health Technology Assessment Regulation (HTAR),1 review of its implications largely sat with European market access, Health Economics and Outcomes Research (HEOR), and regulatory-adjacent teams. Meanwhile, separate teams reviewed US pricing policy, government affairs, and commercial leadership.
With the introduction of Most-Favored-Nation (MFN) policy in the United States (US),2 that separation is becoming increasingly difficult to sustain — and the risk this poses has potentially broad strategic implications. A strong JCA can significantly assist a company’s value story. However, an unfavorable, uncertain, or contested JCA could shape the clinical evidence narrative used in national pricing and reimbursement (P&R) negotiations across Europe. Those national outcomes may then influence European price corridors through international reference pricing (IRP).
This matters because US MFN-style policy mechanisms are increasingly looking to international prices as benchmarks for US drug pricing. The United States Department of Health and Human Services (HHS) has described MFN targets linked to prices in economically comparable countries, and the Centers for Medicare & Medicaid Services (CMS) has since advanced MFN-related models across Medicaid and proposed Medicare Part B and Part D mechanisms.4,5,6
This creates a new global Pricing & Market Access (P&MA) risk frontier that has far-reaching implications. If multiple European payers raise the specter of clinical uncertainty in their negotiations, others may follow suit. IRP can then amplify that pattern, reducing pricing potential, and US MFN-style mechanisms may be used as a benchmark against those unfavorable pricing outcomes.
While this complex new P&MA environment creates uncertainty for biopharma companies, these issues are not insurmountable with careful and early planning around potential price anchors, and a holistic approach to global pricing exposure.
JCA: Not a price decision, but a powerful evidence signal
However, “not binding” should not be confused with “not influential.” A JCA report may become the common clinical evidence starting point for multiple national processes. If the report highlights uncertainty — around comparator relevance, immature survival data, indirect comparisons, subgroup robustness, endpoint validity, or generalizability to European clinical practice — those concerns may weigh on national negotiations.
While a challenging JCA does not automatically lead to poor access or a low price, it can change the burden of proof. It can make national payers more cautious, increase pressure for access restrictions, strengthen demands for rebates or managed entry agreements, and weaken the manufacturer’s ability to build the value narrative across countries.
This differs from national HTA negotiations, where a less favorable conclusion in one market could sometimes be balanced by a more favorable assessment elsewhere. Under the JCA framework, the clinical evidence layer becomes more coordinated, making it harder to compartmentalize evidence challenges market by market.
US MFN: International prices are becoming more relevant
HHS subsequently described expectations that manufacturers align US prices for certain brand products without generic or biosimilar competition with prices in economically comparable countries.3 The US government has reached voluntary MFN agreements with 17 of the largest pharmaceutical companies and other companies are preparing for an expansion of MFN,8 which would likely mean many more brand name drugs and biologics will be impacted.
Additionally, CMS has introduced the voluntary GENEROUS Medicaid model,4 which aims to align Medicaid net prices with prices paid in selected other countries. CMS has also released proposed mandatory MFN initiatives through its GLOBE5 and GUARD6 models for Medicare Part B and Part D, respectively, which would use international benchmarks to assess rebates when US prices exceed prices in comparable countries.
While legal, operational, political, and implementation questions may continue to evolve, the strategic direction is clear: European price outcomes may increasingly matter for US pricing exposure.
Compounding the challenge is the fact that many European markets are economically comparable, commercially significant, and embedded in IRP systems, despite differences in methods across countries.
Meeting the policy collision with smart planning
1. Conduct global price exposure planning
2. Build a cross-functional pricing forum
3. Stress-test the evidence narrative early
4. Map IRP transmission markets
5. Revisit launch sequencing
6. Prepare for multiple US MFN scenarios
The strategic imperative: Integrate — do not retreat
Instead, European launch planning now needs to be more globally integrated. Evidence planning, HTA readiness, national P&R preparation, launch sequencing, contracting, IRP management, and US policy monitoring can no longer be managed in isolation. They need to be connected earlier, governed more tightly, and evaluated through a global pricing lens.
Biopharma leaders should shift their thinking away from “How do we prepare for EU JCA?” or “How do we manage US MFN?” Instead, they should ask: “How do we manage the global pricing consequences of evidence and access decisions in a world where markets are increasingly linked?”
Companies that can answer this question will be better positioned to preserve patient access, sustain price integrity, retain crucial global clinical insights, and maintain strategic flexibility. Early and careful scenario planning will enable companies to be more resilient in a world where evidence narratives and price benchmarks collide.
