Challenges to Arkansas’ Pharmacy Benefit Manager Law
AR SB 688 – Rutledge vs. Pharmaceutical Care Management Association
The Pharmaceutical Care Management Association (PCMA) filed suit against a 2015 Arkansas law that ties reimbursement rates paid to pharmacies by pharmacy benefit managers (PBMs) to pharmacy acquisition cost. The US Court of Appeals for the Eighth Circuit ruled that the law was preempted by the Employee Retirement Income Security Act (ERISA) of 1974. In December 2020, the U.S .Supreme Court ruled that ERISA did not preempt the Arkansas legislation, finding that the statute was primarily directed at cost regulation. In 2021, the Court reaffirmed this decision in a substantively similar case arising from a different Eighth Circuit opinion — Pharm. Care Mgmt. Ass’n v. Tufte (2020).

Challenges to Drug Price Transparency Laws
Pharmaceutical Research and Manufacturers of America (PhRMA) filed suit against a 2017 California law (CA SB 17) that requires pharmaceutical manufacturers to report price increases that meet specified thresholds for drugs sold in the state and to provide a 60-day notice of certain price increases to public and private payers. PhRMA’s complaint claims the law violates the Dormant Commerce Clause (DCC) by regulating interstate commerce, the First Amendment by compelling speech, and the Fourteenth Amendment’s Due Process Clause because it is impermissibly vague. In January 2021, the US District Court for the Eastern District of California rejected both PhRMA’s DCC and First Amendment claims, denying PhRMA’s request for a summary judgement.

Amgen filed suit against California Correctional Health Care Services (CCHCS) to block the release of advance notice of drug price increases per a public record request.
California’s law CA SB 17 requires drug manufacturers to submit a notice to public and private payers 60 days before a drug price increase that surpasses a specified threshold. In 2018, Amgen submitted a notice of pending drug price increases to purchasers registered with the state, including CCHCS. CCHCS later notified Amgen that it planned to release the information to a reporter in response to a California Public Records Act request. Though Amgen obtained a preliminary injunction, CCHCS challenged the ruling, and the injunction was later lifted by the California Court of Appeal, allowing CCHCS to share the information.

The Pharmaceutical Research and Manufacturers of America (PhRMA) challenged two Oregon drug cost transparency laws. HB 4005 requires drug manufacturers to submit pricing information for drugs whose prices increase above a certain threshold, and HB 2658 requires manufacturer to report specified price increases to the state at least 60 days before they take effect.
PhRMA argues the laws violate the Dormant Commerce Clause by restricting drug prices nationwide, the First Amendment by compelling speech, and the Fifth Amendment Takings Clause. PhRMA also claims the laws are preempted by the Defend Trade Secrets Act.

PhRMA’s Initial Complaint 12/9/19
Pharmaceutical Research and Manufacturers of America (PhRMA) and the Biotechnology Innovations Organization (BIO) challenged a Nevada law SB 539 that requires manufacturers and pharmacy benefit managers to report pricing information for essential diabetes medications. PhRMA and BIO argued that the law was pre-empted by federal patent law and the Defend Trade Secrets Act and that it violated the Fifth Amendment Takings Clause and the Dormant Commerce Clause.
The associations dropped the lawsuit in June 2018 after Nevada’s Department of Health and Human Services adopted regulations that allow manufacturers and pharmacy benefit managers to request that specific price report information be kept confidential.

- PhRMA and BIO’s initial complaint 9/1/2017

CA AB 824 Challenge to California’s Pay-for-Delay Law (Association for Accessible Medicines vs. Becerra)
CA AB 824 established that if a generic manufacturer receives anything of value from a brand-name drug manufacturer that has sued for patent infringement, such “pay-for-delay” agreements are anticompetitive – unless a company can prove otherwise. The Association for Accessible Medicines (AAM) claims the California’s pay-for-delay law violates the Dormant Commerce Clause, prohibitions on excessive fines, due process and federal patent law.
In December 2019, the U.S. District Court for the Eastern District of California denied AAM’s request for a preliminary injunction. AAM then appealed to the Ninth Circuit Court of Appeals, which recommended the District Court dismiss the case because AAM did not establish standing. The District Court dismissed the case, in line with the Ninth Circuit’s recommendation. In August 2020, AAM refiled its complaint with the US District Court, including additional evidence in an attempt to establish standing. The District Court granted AAM’s motion for a preliminary injunction in December 2021. In February 2022, however, the federal District Court modified the injunction to permit California to enforce only those “provisions of AB 824 with respect to settlement agreements negotiated, completed, or entered into within California’s borders.” The District Court reasoned this would avoid DCC concerns since these agreements only “regulate conduct occurring wholly within California’s borders.” The modified preliminary injunction will remain in effect as the parties prepare for trial, unless the court further amends its order.

- US District Court (E.D. Cal.) modifies preliminary injunction to enforce provisions against wholly California-based settlement agreements
- AAM’s initial complaint 11/12/19

Challenge to Minnesota’s Insulin Affordability Law
MN HF 3100: Pharmaceutical Research and Manufacturers of America vs. Williams et al – Pharmaceutical Research and Manufacturers of America (PhRMA) filed a lawsuit against the members of the Board of Pharmacy and the Board of MNSure to stop the implementation of a law that requires insulin manufacturers to make insulin available to eligible individuals who are in urgent need of affordable insulin. PhRMA argues that HF 3100 violates the Fifth Amendment Takings Clause because it requires manufacturers to provide insulin for a certain price. In March 2021, the U.S. District Court of Minnesota dismissed the lawsuit, ruling that there had been no “taking” when the case was filed, and that PhRMA would have to show that they had sought compensation for the alleged taking and had been unsuccessful. PhRMA appealed the District Court’s ruling to the Eighth Circuit, arguing before a three-judge panel in December 2021.
Filings:
- PhRMA’s initial complaint 6/30/20
- Board of Pharmacy and Board of MNSure’s motion to dismiss PhRMA’s lawsuit 8/27/2020
Challenge to Maryland’s Anti-Price-Gouging Law
MD HB 631: Association for Accessible Medicines vs. Frosh
The Association for Accessible Medicines (AAM) filed a lawsuit challenging Maryland’s anti-price-gouging law in US District Court for the District of Maryland. AAM argued that the law violated the Dormant Commerce Clause (DCC) by regulating commerce outside the state and that it was impermissibly vague. The District Court for Maryland dismissed most of AAM’s suit, but AAM appealed and the Fourth Circuit Court of Appeals overturned the District Court’s decision, ruling that the law violated the DCC. The US Supreme Court rejected the attorney general’s request to review the Fourth Circuit’s decision.

These legal analyses, written by NASHP experts, address key issues that the pharmaceutical industry raises in its legal challenges of state actions to contain drug costs.
States have passed an unprecedented number of laws addressing drug prices over the past few years and some have faced legal challenges. This NASHP legal brief, Navigating Legal Challenges to State Efforts to Control Drug Prices: PBM Regulation, Price Gouging, and Price Transparency, by Katherine L. Gudiksen, PhD, Samuel M. Chang, JD, and Jaime S. King, JD, PhD, explores those challenges. The brief analyzes the arguments industry groups have made against pharmacy benefit manager regulations, anti-price-gouging laws, and drug price transparency requirements using the Dormant Commerce Clause and federal patent and trade secret laws.
Dormant Commerce Clause
When states pass laws designed to control prescription drug costs, the pharmaceutical industry often responds with lawsuits claiming states are hindering interstate commerce and violating the federal Dormant Commerce Clause (DCC). NASHP’s legal experts believe states can craft drug cost policies that can withstand industry challenges.
This brief by Anna Zaret, JD, and Darien Shankse, PhD, JD, MA, provides insight and analysis about DCC case law and highlights what state policymakers need to consider when drafting drug cost polices.

For individuals living with complex, often chronic conditions, and their families, palliative care can provide relief from symptoms, improve satisfaction and outcomes, and help address critical mental and spiritual needs during difficult times. Now more than ever, there is growing recognition of the importance of palliative care services for individuals with serious illness, such as advance care planning, pain and symptom management, care coordination, and team-based, multi-disciplinary support. These services can help patients and families cope with the symptoms and stressors of disease, better anticipate and avoid crises, and reduce unnecessary and/or unwanted care. While this model is grounded in evidence that demonstrates improved quality of life, better outcomes, and reduced cost for patients, only a fraction of individuals who could benefit from palliative care receive it.
