The federal drug pricing landscape continues to undergo significant transformation as executive branch agencies advance an ambitious suite of regulatory and model testing initiatives intended to lower the costs associated with the Medicare and Medicaid programs. In response to ongoing concerns about rising out-of-pocket costs, increasing pressure to align US prices with those paid internationally, and the continued implementation of the Inflation Reduction Act (IRA), federal agencies are reshaping how prescription drugs are priced, reimbursed, and negotiated in federally financed programs.
The current policy environment reflects a growing emphasis on benchmarking drug prices to those in peer nations, referred to as 鈥渕ost favored nation鈥� (MFN) benchmarks, and accelerating actions that require or encourage manufacturers to offer lower net prices. 红领巾瓜报 (红领巾瓜报), is tracking these developments in the public payer space, replicating Centers for Medicare & Medicaid Services (CMS) payment methodologies, and modeling alternative policies to assist life science companies, payers, and other stakeholders.
In this article, we review the administration鈥檚 recent efforts to reduce Medicare and Medicaid spending on drugs and biologics, including confidential manufacturer negotiations and three new models that together could reshape pricing dynamics across federal programs.
Executive Branch Negotiations Seek to Drive Access to MFN Discounts
In 2025, the administration issued an directing federal agencies to pursue strategies to establish MFN pricing, linking US prices for certain drugs to the lowest (or second lowest) adjusted net prices among a targeted set of peer countries. Following the order, federal officials sent to 17 major pharmaceutical and biotechnology manufacturers, urging them to negotiate agreements that would voluntarily align prices with MFN-based benchmarks.
To date, 14 manufacturers have signed , though full details remain confidential. These agreements are understood to accomplish the following:
- Provide听state听Medicaid听programs with听access to听MFNbased听discounts听
- Require that new drugs be launched in the United听States听at听MFNaligned听prices听
- Offer certain drugs at discounted听directtoconsumer听prices through a forthcoming 鈥淭rumpRx鈥� program, expected to launch later this year听
Reports suggest that manufacturers entering these MFN-related arrangements may receive exemptions from several federal actions, including the Center for Medicare and Medicaid Innovation (Innovation Center) demonstration models described below and certain tariff-related policies.
MFNLinked Models Designed to Lower Drug Costs Across Medicare and Medicaid
Along with the negotiation efforts, the CMS Innovation Center has proposed three models that would test MFNbased pricing through structured rebate mechanisms. Each model targets different segments of the market while testing how international benchmarks could be integrated into federal drug payment policy.
New Models Test Alternatives to Inflation Rebates
Announced in December 2025, the and the are designed to test alternative approaches to the Inflation Reduction Act鈥檚 (IRA) policies. CMS plans to test the models鈥� potential for market driven price reductions if manufacturers choose to lower list prices instead of paying MFN-based rebates.
Key features of the GLOBE Model are as follows:
- Applies听to听25 percent of听Medicare听fee-for-service听(FFS)听beneficiaries听using certain听Part B drugs听
- Beginning in October 2026,听becomes听mandatory听for select drugs and targets听highspending,听physicianadministered听Part B categories, excluding products already subject to IRA听negotiations, generics, biosimilars, and certain听lowspend听products听
- No changes to听physician and hospital听reimbursement,听although beneficiaries听expected to听see reduced cost sharing听
The GUARD Model will similarly test whether applying MFN-based rebates to Medicare Part D drugs will lower Medicare costs. Key aspects of this model include:
- Fiveyear听model听that would start听January 1, 2027听
- Target听therapeutic categories with more than $69 million in annual Part D spending听
- No impact on听plan bids and beneficiary cost sharing听
These models rely on pricing data from 19 countries. Manufacturers that voluntarily submit net price information would trigger quarterly benchmark updates; otherwise, CMS will use a fixed list price based benchmark for the entire pilot period.
CMS is seeking on whether additional categories, for example cell and gene therapies, should be excluded from GLOBE. GUARD is also open for through February 23, 2026.
GENErating cost Reductions fOr US Medicaid (GENEROUS) Model
The , expected to begin in 2026, creates a voluntary pathway for state Medicaid programs and manufacturers to enter supplemental rebate agreements tied to MFNaligned prices. MFN pricing under this model is based on the second lowest net price in G7 countries plus Denmark and Switzerland. GENEROUS is also expected to align with pricing commitments negotiated through the administration鈥檚 manufacturer agreements.
Key Considerations and Potential Impacts
The combined effect of federal negotiations and Innovation Center models could be substantial, though outcomes will depend on manufacturer participation, benchmark stability, and operational feasibility. Key considerations include:
- State听Medicaid savings, especially听the extent to which听MFN鈥憀inked rebates exceed existing supplemental rebates听
- Reduced Medicare beneficiary cost sharing for Part B included in GLOBE听
- Shifts in manufacturer pricing strategies, including potential changes to US launch prices听
- Interactions with the IRA, particularly Part D redesign and Part B inflation penalties听
