WYETH, PETITIONER v. DIANA LEVINE

 
SUPREME COURT OF THE UNITED STATES

 

March 4, 2009, Decided

SYLLABUS

Petitioner Wyeth manufactures the antinausea drug Phenergan. After a clinician injected respondent Levine with Phenergan by the "IV-push" method, whereby a drug is injected directly into a patient's vein, the drug entered Levine's artery, she developed gangrene, and doctors amputated her forearm. Levine brought a state-law damages action, alleging, inter alia, that Wyeth had failed to provide an adequate warning about the significant risks of administering Phenergan by the IV-push method. The Vermont jury determined that Levine's injury would not have occurred if Phenergan's label included an adequate warning, and it awarded damages for her pain and suffering, substantial medical expenses, and loss of her livelihood as a professional musician. Declining to overturn the verdict, the trial court rejected Wyeth's argument that Levine's failure-to-warn claims were pre-empted by federal law because Phenergan's labeling had been approved by the federal Food and Drug Administration (FDA). The Vermont Supreme Court affirmed.

Held: Federal law does not pre-empt Levine's claim that Phenergan's label did not contain an adequate warning about the IV-push method of administration.

(a) The argument that Levine's state-law claims are pre-empted because it is impossible for Wyeth to comply with both the state-law duties underlying those claims and its federal labeling duties is rejected. Although a manufacturer generally may change a drug label only after the FDA approves a supplemental application, the agency's "changes being effected" (CBE) regulation permits certain preapproval labeling changes that add or strengthen a warning to improve drug safety. Pursuant to the CBE regulation, Wyeth could have unilaterally added a stronger warning about IV-push administration, and there is no evidence that the FDA would ultimately have rejected such a labeling change. Wyeth's cramped reading of the CBE regulation and its broad assertion that unilaterally changing the Phenergan label would have violated federal law governing unauthorized distribution and misbranding of drugs are based on the fundamental misunderstanding that the FDA, rather than the manufacturer, bears primary responsibility for drug labeling. It is a central premise of the Food, Drug, and Cosmetic Act (FDCA) and the FDA's regulations that the manufacturer bears responsibility for the content of its label at all times.

(b) Wyeth's argument that requiring it to comply with a state-law duty to provide a stronger warning would interfere with Congress' purpose of entrusting an expert agency with drug labeling decisions is meritless because it relies on an untenable interpretation of congressional intent and an overbroad view of an agency's power to pre-empt state law. The history of the FDCA shows that Congress did not intend to pre-empt state-law failure-to-warn actions. In advancing the argument that the FDA must be presumed to have established a specific labeling standard that leaves no room for different state-law judgments, Wyeth relies not on any statement by Congress but on the preamble to a 2006 FDA regulation declaring that state-law failure-to-warn claims threaten the FDA's statutorily prescribed role. Although an agency regulation with the force of law can pre-empt conflicting state requirements, this case involves no such regulation but merely an agency's assertion that state law is an obstacle to achieving its statutory objectives. Where, as here, Congress has not authorized a federal agency to pre-empt state law directly, the weight this Court accords the agency's explanation of state law's impact on the federal scheme depends on its thoroughness, consistency, and persuasiveness. Under this standard, the FDA's 2006 preamble does not merit deference: It is inherently suspect in light of the FDA's failure to offer interested parties notice or opportunity for comment on the pre-emption question; it is at odds with the available evidence of Congress' purposes; and it reverses the FDA's own longstanding position that state law is a complementary form of drug regulation without providing a reasoned explanation.

JUDGES: STEVENS, J., delivered the opinion of the Court, in which KENNEDY, SOUTER, GINSBURG, and BREYER, JJ., joined. BREYER, J., filed a concurring opinion. THOMAS, J., filed an opinion concurring in the judgment. ALITO, J., filed a dissenting opinion, in which ROBERTS, C. J., and SCALIA, J., joined.

JUSTICE STEVENS delivered the opinion of the Court.

Directly injecting the drug Phenergan into a patient's vein creates a significant risk of catastrophic consequences. A Vermont jury found that petitioner Wyeth, the manufacturer of the drug, had failed to provide an adequate warning of that risk and awarded damages to respondent Diana Levine to compensate her for the amputation of her arm. The warnings on Phenergan's label had been deemed sufficient by the federal Food and Drug Administration (FDA) when it approved Wyeth's new drug application in 1955 and when it later approved changes in the drug's labeling. The question we must decide is whether the FDA's approvals provide Wyeth with a complete defense to Levine's tort claims. We conclude that they do not.

Wyeth makes two separate pre-emption arguments: first, that it would have been impossible for it to comply with the state-law duty to modify Phenergan's labeling without violating federal law, and second, that recognition of Levine's state tort action creates an unacceptable "obstacle to the accomplishment and execution of the full purposes and objectives of Congress," Hines v. Davidowitz, 312 U.S. 52, 67 (1941), because it substitutes a lay jury's decision about drug labeling for the expert judgment of the FDA. As a preface to our evaluation of these arguments, we identify two factual propositions decided during the trial court proceedings, emphasize two legal principles that guide our analysis, and review the history of the controlling federal statute.

The trial court proceedings established that Levine's injury would not have occurred if Phenergan's label had included an adequate warning about the risks of the IV-push method of administering the drug. In finding Wyeth negligent as well as strictly liable, the jury also determined that Levine's injury was foreseeable. That the inadequate label was both a but-for and proximate cause of Levine's injury is supported by the record and no longer challenged by Wyeth.

The trial court proceedings further established that the critical defect in Phenergan's label was the lack of an adequate warning about the risks of IV-push administration. Levine also offered evidence that the IV-push method should be contraindicated and that Phenergan should never be administered intravenously, even by the IV-drip method. The jury verdict established only that Phenergan's warning was insufficient. It did not mandate a particular replacement warning, nor did it require contraindicating IV-push administration: "There may have been any number of ways for [Wyeth] to strengthen the Phenergan warning without completely eliminating IV-push administration." We therefore need not decide whether a state rule proscribing intravenous administration would be pre-empted. The narrower question presented is whether federal law pre-empts Levine's claim that Phenergan's label did not contain an adequate warning about using the IV-push method of administration.

Our answer to that question must be guided by two cornerstones of our pre-emption jurisprudence. First, "the purpose of Congress is the ultimate touchstone in every pre-emption case." Medtronic, Inc. v. Lohr, 518 U.S. 470, 485 (1996). Second, "[i]n all pre-emption cases, and particularly in those in which Congress has 'legislated . . . in a field which the States have traditionally occupied,' . . . we 'start with the assumption that the historic police powers of the States were not to be superseded by the Federal Act unless that was the clear and manifest purpose of Congress.'"

Wyeth first argues that Levine's state-law claims are pre-empted because it is impossible for it to comply with both the state-law duties underlying those claims and its federal labeling duties. The FDA's premarket approval of a new drug application includes the approval of the exact text in the proposed label. Generally speaking, a manufacturer may only change a drug label after the FDA approves a supplemental application. There is, however, an FDA regulation that permits a manufacturer to make certain changes to its label before receiving the agency's approval. Among other things, this "changes being effected" (CBE) regulation provides that if a manufacturer is changing a label to "add or strengthen a contraindication, warning, precaution, or adverse reaction" or to "add or strengthen an instruction about dosage and administration that is intended to increase the safe use of the drug product," it may make the labeling change upon filing its supplemental application with the FDA; it need not wait for FDA approval.

Wyeth argues that the CBE regulation is not implicated in this case because a 2008 amendment provides that a manufacturer may only change its label "to reflect newly acquired information." Resting on this language, Wyeth contends that it could have changed Phenergan's label only in response to new information that the FDA had not considered. And it maintains that Levine has not pointed to any such information concerning the risks of IV-push administration. Thus, Wyeth insists, it was impossible for it to discharge its state-law obligation to provide a stronger warning about IV-push administration without violating federal law. Wyeth's argument misapprehends both the federal drug regulatory scheme and its burden in establishing a pre-emption defense.

We need not decide whether the 2008 CBE regulation is consistent with the FDCA and the previous version of the regulation because Wyeth could have revised Phenergan's label even in accordance with the amended regulation. As the FDA explained in its notice of the final rule, "'newly acquired information'" is not limited to new data, but also encompasses "new analyses of previously submitted data." The rule accounts for the fact that risk information accumulates over time and that the same data may take on a different meaning in light of subsequent developments: "[I]f the sponsor submits adverse event information to FDA, and then later conducts a new analysis of data showing risks of a different type or of greater severity or frequency than did reports previously submitted to FDA, the sponsor meets the requirement for 'newly acquired information.'"

The record is limited concerning what newly acquired information Wyeth had or should have had about the risks of IV-push administration of Phenergan because Wyeth did not argue before the trial court that such information was required for a CBE labeling change. Levine did, however, present evidence of at least 20 incidents prior to her injury in which a Phenergan injection resulted in gangrene and an amputation. After the first such incident came to Wyeth's attention in 1967, it notified the FDA and worked with the agency to change Phenergan's label. In later years, as amputations continued to occur, Wyeth could have analyzed the accumulating data and added a stronger warning about IV-push administration of the drug.

Wyeth argues that if it had unilaterally added such a warning, it would have violated federal law governing unauthorized distribution and misbranding. Its argument that a change in Phenergan's labeling would have subjected it to liability for unauthorized distribution rests on the assumption that this labeling change would have rendered Phenergan a new drug lacking an effective application. But strengthening the warning about IV-push administration would not have made Phenergan a new drug. Nor would this warning have rendered Phenergan misbranded.

Wyeth's cramped reading of the CBE regulation and its broad reading of the FDCA's misbranding and unauthorized distribution provisions are premised on a more fundamental misunderstanding. Wyeth suggests that the FDA, rather than the manufacturer, bears primary responsibility for drug labeling. Yet through many amendments to the FDCA and to FDA regulations, it has remained a central premise of federal drug regulation that the manufacturer bears responsibility for the content of its label at all times. It is charged both with crafting an adequate label and with ensuring that its warnings remain adequate as long as the drug is on the market.

Indeed, prior to 2007, the FDA lacked the authority to order manufacturers to revise their labels. When Congress granted the FDA this authority, it reaffirmed the manufacturer's ultimate responsibility for its label. Thus, when the risk of gangrene from IV-push injection of Phenergan became apparent, Wyeth had a duty to provide a warning that adequately described that risk, and the CBE regulation permitted it to provide such a warning before receiving the FDA's approval.

Of course, the FDA retains authority to reject labeling changes made pursuant to the CBE regulation in its review of the manufacturer's supplemental application, just as it retains such authority in reviewing all supplemental applications. But absent clear evidence that the FDA would not have approved a change to Phenergan's label, we will not conclude that it was impossible for Wyeth to comply with both federal and state requirements. Wyeth has offered no such evidence. We accordingly cannot credit Wyeth's contention that the FDA would have prevented it from adding a stronger warning about the IV-push method of intravenous administration.

Impossibility pre-emption is a demanding defense. On the record before us, Wyeth has failed to demonstrate that it was impossible for it to comply with both federal and state requirements. The CBE regulation permitted Wyeth to unilaterally strengthen its warning, and the mere fact that the FDA approved Phenergan's label does not establish that it would have prohibited such a change.

IV

Wyeth also argues that requiring it to comply with a state-law duty to provide a stronger warning about IV-push administration would obstruct the purposes and objectives of federal drug labeling regulation. Levine's tort claims, it maintains, are pre-empted because they interfere with "Congress's purpose to entrust an expert agency to make drug labeling decisions that strike a balance between competing objectives." We find no merit in this argument, which relies on an untenable interpretation of congressional intent and an overbroad view of an agency's power to pre-empt state law.

Wyeth contends that the FDCA establishes both a floor and a ceiling for drug regulation: Once the FDA has approved a drug's label, a state-law verdict may not deem the label inadequate, regardless of whether there is any evidence that the FDA has considered the stronger warning at issue. The most glaring problem with this argument is that all evidence of Congress' purposes is to the contrary. Building on its 1906 Act, Congress enacted the FDCA to bolster consumer protection against harmful products.

If Congress thought state-law suits posed an obstacle to its objectives, it surely would have enacted an express pre-emption provision at some point during the FDCA's 70-year history. But despite its 1976 enactment of an express pre-emption provision for medical devices, Congress has not enacted such a provision for prescription drugs. Its silence on the issue, coupled with its certain awareness of the prevalence of state tort litigation, is powerful evidence that Congress did not intend FDA oversight to be the exclusive means of ensuring drug safety and effectiveness. As Justice O'Connor explained in her opinion for a unanimous Court: "The case for federal pre-emption is particularly weak where Congress has indicated its awareness of the operation of state law in a field of federal interest, and has nonetheless decided to stand by both concepts and to tolerate whatever tension there [is] between them." Bonito Boats, Inc. v. Thunder Craft Boats, Inc., 489 U.S. 141, 166-167 (1989).

In short, Wyeth has not persuaded us that failure-to-warn claims like Levine's obstruct the federal regulation of drug labeling. Congress has repeatedly declined to pre-empt state law. Although we recognize that some state-law claims might well frustrate the achievement of congressional objectives, this is not such a case.

V

We conclude that it is not impossible for Wyeth to comply with its state and federal law obligations and that Levine's common-law claims do not stand as an obstacle to the accomplishment of Congress' purposes in the FDCA. Accordingly, the judgment of the Vermont Supreme Court is affirmed.

 

JUSTICE THOMAS, concurring in the judgment.

I agree with the Court that the fact that the Food and Drug Administration (FDA) approved the label for petitioner Wyeth's drug Phenergan does not pre-empt the state-law judgment before the Court. I write separately, however, because I cannot join the majority's implicit endorsement of far-reaching implied pre-emption doctrines. In particular, I have become increasingly skeptical of this Court's "purposes and objectives" pre-emption jurisprudence. Under this approach, the Court routinely invalidates state laws based on perceived conflicts with broad federal policy objectives, legislative history, or generalized notions of congressional purposes that are not embodied within the text of federal law. Because implied pre-emption doctrines that wander far from the statutory text are inconsistent with the Constitution, I concur only in the judgment.
