_________________ KAREN NELSON MOORE, Circuit Judge. Vicki Marsh, Shay Blair, David Tiefenthal, and the Estate of Eddie Muniz (co llectively, “Marsh”), the plaintiffs in these consolidated products-liability actions, brought suit against drug manufacturers Genentech, Inc. and Xoma (U.S.) LLC (collec tively, “Genentech”) to recover for injuries allegedly sustained from use of the psoriasis medication Raptiva. The district court granted Genentech’s motion to dismiss, holding that Gene ntech was entitled to immunity under the Michigan Products Liability Act (the Act) and that Marsh’s claim that immunity did not apply was preempted by federal law. Because the allegations underlying Marsh’s argument that immunity does not apply are essentially the type of claim that Supreme Court and Sixth Circu it precedent holds is preempted, we AFFIRM.

I. BACKGROUND Genentech designed, manufactured, and so ld the psoriasis medication Raptiva, which was approved by the federal Food and Drug Administration (“FDA”) in 2003 and sold in the United States from 2003 until 2009. Raptiva works by suppressing T-cells to prevent them from migrating to the skinand causing psoriasis. Because T-cells helpfight infections, however, their suppression has the potential to cause potentially lifethreatening side effects. Following reports of adverse health effects, including a rare brain infection, in patients treated with Raptiva, Genentech voluntarily removed Raptiva from the market in 2009. Marsh began using Raptiva in 2004 and subsequently suffered viral meningitis and a collapsed lung; she attributes th ese conditions to her use of Raptiva. 1 She brought suit against Genentech in 2011, alleging strict products liability under design-defect and failure-to-warn theories, negligence, breach of warranty, and fraud. She contends that,Nos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 3

2 With the exception of factual allegations related to each plaintiff’s use of Raptiva and adverse health effects, the four complaints are identical. Wefollow both the parties’ briefs and the district court in citing Marsh’s complaint. both prior to and after FDA approval of Raptiva, Genentech knew of dangerous side effects that it concealed from the public and did not include in the drug’s label. Marsh also alleged that Genentech “intentionally and negligently failed to update statement of contraindications, warnings, precautions, and adverse reactions that Defendant affirmatively knew about” and “intentionallyand negligently failed to comply with various but not limited to, 21 CF R 201, 21 CFR 202, 21 CF R 314.80, and 21 CFR 314.81.” R.1 (Marsh Complaint) at ¶¶ 110–111 (PageID #27). 2
Following a transfer of venue, Genentechmoved to dismiss on the grounds that it was immune from suit under the state Act, which provides that drug manufacturers are not liable in products-liability actions if th e allegedly dangerous drug and its label were approved by the FDA and were in compliance with the FDA’s approval at the time that the drug left the manufacturer’s control. See Mich. Comp. Laws § 600.2946(5). Marsh countered that Genentech was not entitled to immunity because it failed to submit updated safety information to the FDA after Raptiva had gone to market or otherwise comply with various FDA regulations regarding post-marketing reporting, which was a condition of FDA approval. The district court granted Genentech’s motion to dismiss, holding that Genentech was immune from suit because neither st atutory exception to immunity for drug manufacturers—that the manufacturer had defrauded or bribed the FDA—applied. Citing our decision in Garcia v. Wyeth-Ayerst Laboratories , 385 F.3d 961 (6th Cir. 2004), the district court explained that federal law preempts tort claims premised on the Act’s exceptions absent a finding by the FDA itself that the manufacturer had committed fraud or bribery. The district court concl uded that, because Marsh had not alleged that the FDA had found that Genentech committe d fraud, her claim was preempted. The district court subsequently denied Marsh’s motion for reconsideration. Marsh timely appealed.Nos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 4

On appeal, Marsh again contends th at immunity does not apply becauseGenentech’s failure to submit updated safety information rendered Raptiva noncompliant with the FDA’s approval at the time it left Genentech’s control. Because her claim is premised on non-compliance rather than the fraud exception, she argues that it is not preempted under Garcia . In addition, she characterizes this suit as the type of state-law tort claim that the Suprem e Court held was not preempted in Wyeth v. Levine , 555 U.S. 555 (2009). Finally, Marsh argues that immunity is an affirmative defense and thus that the district court erred by not requiring Genentech to prove Raptiva’s compliance with the FDA’s approval after Marsh alleged non-compliance in the complaint. In response, Genentech characterizes failure to submit safety update reports as a species of fraud that falls within the Act’ s first exception and is thus preempted absent a finding of fraud by the FDA. Alternatively, Genentech argues that Marsh’s claim is preempted under Garcia regardless of how it is characterized.

II. JURISDICTION AND STANDARD OF REVIEW We have jurisdiction over this diversity action pursuant to 28 U.S.C. § 1332. Both parties agree that Michig an law applies. We review the district court’s grant of Genentech’s motion to dismiss de novo. Brown v. Cassens Transp. Co. , 675 F.3d 946, 953 (6th Cir. 2012).

III. ANALYSIS A. Implied Preemption and Michigan Products-Liability Law Michigan’s products-liability regime is statutory. A drug manufacturer or seller is not liable for injuries caused by the use of its products “if th e drug was approved for safety and efficacy by the United States f ood and drug administration, and the drug and its labeling were in compliance with the United States food and drug administration’s approval at the time the drug left the contro l of the manufacturer or seller.” Mich. Comp. Laws § 600.2946(5). As a matter of law, “a drug is not defective or unreasonablyNos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 5

3 We also held that the Act’s exceptions are not preempted when the FDA itself has determined that the manufacturer committed fraud or bribery. Because Marsh does not contend that the FDA made such a determination, this aspect of Garcia has no bearing on this case.
4 As relevant for this case, fede ral law impliedly preempts a state law if the state law “creates an unacceptable ‘obstacle to the accomplishment and ex ecution of the full purposes and objectives of Congress.’” Wyeth , 555 U.S. at 563–64 (quoting Hines v. Davidowitz , 312 U.S. 52, 67 (1941)). The Supreme Court has identified two “cornerstones of . . . pre-emption jurispruden ce”: “First, the purpose of Congress is the ultimate touchstone in every pre- emption case. Second, in 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 hi storic police powers of the States were not to be superseded by the Federal Act unless that was the clear and manifest purpose of Congress.” Id. at 565 (internal quotation marks, citations, and alterations omitted). dangerous” if such criteria are met. Id. Statutory immunity does not apply, however, if the manufacturer or seller: (a) Intentionally withholds from or misrepresents to the United States food and drug administration inform ation concerning the drug that is required to be submitted under the fe deral food, drug, and cosmetic act, chapter 675, 52 Stat. 1040, 21 U.S.C. 301 to 321, 331 to 343-2, 344 to 346a, 347, 348 to 353, 355 to 360, 360b to 376, and 378 to 395, and the drug would not have been approved, or the United States food and drug administration would have withdrawn approval for the drug if the information were accurately submitted.

or (b) Makes an illegal payment to an official or employee of the United States food and drug administration for the purpose of securing or maintaining approval of the drug.

Id. The Michigan Supreme Court has described the Act’s immunity provision as “an absolute defense to a products liability claim” premised on the determination that “compliance with federal governmental standards (established by the FDA) is conclusive on the issue of due care for drugs.” Taylor v. SmithKline Beecham Corp. , 658 N.W.2d 127, 130–31 (Mich. 2003).

In Garcia , 385 F.3d at 965–66, we held that fede ral law impliedly preempts the Act’s two exceptions. 3 In so holding, we relied on Buckman Co. v. Plaintiffs’ Legal Committee , 531 U.S. 341 (2001), in which the Supreme Court held that the federal Food, Drug, and Cosmetic Act (“FDCA”) impliedly preempts state-law fraud-on-the-FDA claims. 4Nos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 6

The plaintiffs in Buckman brought suit against a medical-device manufacturer under state law, alleging that the manufacturer had made fraudulent representations to the FDA in the course of the approval process and that, as a result, the device was improperly placed on the market. 531 U.S. at 346–47. The Court held that such claims are preempted because they in terfere with the federal regulatory scheme for the approval of drugs and medical devices, id. at 348–50, and because they implicate the “inherently federal” issue of “the relationship between a federal agency and the entity it regulates,” id. at 347. Indeed, because “[p]olicing fraud ag ainst federal agencies is hardly ‘a field which the States have traditionally occupied,’” the traditional presumption against preemption did not apply. Id. (quoting Rice v. Santa Fe Elevator Corp. , 331 U.S. 218, 230 (1947)). The FDCA sets forth a “comprehensive scheme” of disclosure requirements as part of the approval process. Id. at 348. Along with these requirements, the FDCA empowers the FDA to investigate and penali ze fraud in a manufacturer’s disclosures or elsewhere in the approval process. Id. at 348–49. The Court viewed these provisions of the FDCA as evidence that Congress in tended exclusively federal enforcement. Id. at 352. State-law fraud-on-the-FDA claims would thus “inevitably conflict with the FDA’s responsibility to police fraud consistently with the Administration’s judgment and objectives” by allowing state courts to rule on the adequacy of a manufacturer’s disclosures. Id. at 350. These claims could also interfere with the FDA’s approval process, because the possibility that “disclosures to the FDA, although deemed appropriate by the Administration, will later bejudged insufficient in state court” could lead manufacturers to oversubmit information and thus burden the evaluation process. Id. at 351.
At its core, a fraud-on-the-FDA claim im plicates “the relationship between a federal agency and the entity it regulates,” a relationship that is “inherently federal in character.” Id. at 347. Moreover, the basis for the cl aim is violation of a federal statute or regulation. Unlike a common-law tort claim, these “fraud claims exist solely by virtue of the FDCA disclosure requirements.” Id. at 352–53. The alleged wrong isNos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 7

5 We also held that the fraud exceptions are not preempted “when the federal agency itself determines that fraud marred the regulatory-approval process.” Garcia , 385 F.3d at 966. Accordingly, “claims based on federal findings of bribery or fraud on the FDA” can defeat manufacturer immunity under the state Act. Id.
6 At oral argument, Marsh cited the Second Circuit’s opinion in Desiano v. Warner-Lambert & Co. , 467 F.3d 85 (2d Cir. 2007), aff’d by an equally divided court sub nom. Warner-Lambert Co. v. Kent , 552 U.S. 440, 441 (2008), which held that the Michigan Act’s exceptions were not preempted because, unlike in a stand-alone fraud-on-the-FDA claim, plaintiffs’ claims under the Act are traditional tort claims that do not contain fraud as an element. We are, of course, bound by our own published precedent in Garcia to the contrary. inadequate disclosure to a federal agency rather than breach of the common-law duty to use reasonable care. Id. Following Buckman , we held in Garcia that suits against drug manufacturers under Michigan law in which the plaintiff seeks to defeat immunity by invoking the Act’s fraud exceptions are equivalent to fraud-on-the-FDA claims and are thus preempted. Garcia , 385 F.3d at 965–66. 5 Even though, under Michigan law, fraud on the FDA is an exception to a gr ant of immunity to the manufacturer rather than a standalone cause of action, it nonetheless ultimately “requir[es] proof of fraud committed against the FDA” to succeed. Id. (internal quotation marks omitted). Garcia thus essentially requires treating a plaintiff’s fraud arguments against manufacturer immunity as a threshold “claim” that can be preempted. 6 We subsequently held that Garcia applied to claims that the manufacturer mi srepresented or withheld information about a drug from the FDA after the FDA had approved it. In re Aredia & Zometa Prods. Liab. Litig. , 352 F. App’x 994, 995 (6th Cir. 2009) (unpublished opinion) (holding that such claims are preempted under the FDCA “unless some federal agency has already found the requisite fraud on the FDA”). Subsequent to Buckman and Garcia , the Supreme Court again dealt with the implied preemptive effect of the FDCA on state-law tort claims against drug manufacturers. In Wyeth , 555 U.S. at 558–59, the Court heldthat a state-law failure-towarn claim premised on the inadequacy of a brand-name drug’s label was not preempted simply because the FDA had approved the label. The manufacturer could still be liable under state law for failing to update th e drug’s label based on newly acquired information. See id. at 571. Because Congress has not provided a federal cause ofNos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 8

action for consumers harmed by unsafe drugs, state-law failure-to-warn claims provide “an additional, and important, layer of c onsumer protection that complements FDA regulation.” Id. at 579. B. Compliance With FDA Approval Marsh would protest that the above analysis is an irrelevant detour, because she does not invoke the Act’s fraud exception. In stead, her argument that immunity does not apply is premised on Genentech’s alleged non-compliance with the terms of the FDA’s approval of Raptiva. Whatever vitality this distinction might have in other circumstances, the nature of Marsh’s allegations of non-compliance does not take this case outside of Garcia ’s precedential reach. As described above, the state Act provide s immunity from liability if “the drug and its labeling were in compliance with the United States food and drug administration’s approval at the time the drug left the control of the manufacturer or seller.” Mich. Comp. Laws § 600.2946(5). The Act does not define “compliance with [FDA] approval,” and the parties have not cited, and we have not found, any Michigan caselaw interpreting this requirement. The nature of Marsh’s allegations of non-compliance is somewhat obscure, but she seems to allege that Genentech failed to comply with the FDA’s post-marketing reporting requirements. The complaint alleges that Genentech “intentionally and negligently failed to update statement of contraindications, warnings, precautions, and adverse reactions that Defendant affirmatively knew about” and “intentionally and negligently failed to comply with various but not limited to, 21 CFR 201, 21 CFR 202, 21 CFR 314.80, and 21 CFR 314.81.” R.1 at ¶¶ 110–111 (Page ID #27). Marsh contends that these failure s constitute non-compliance withthe FDA’s approval because, as part of its application for approval of Raptiva, Genentech signed FDA Form 356h, which requires the applicant to certify as follows: “I agree to update this application w ith new safety information about the product that may reasonably affect the statement of contraindicaitons [sic], warnings, precautions or advers e reactions in the draft labeling. INos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 9

7 The complaint’s C.F.R. citations support this vi ew of Marsh’s allegations. Sections 314.80 and 314.81 set forth post-marketing reporting requirements. Section 201 governs labeling, which would seem more relevant, but that section has seven subparts and seventy-one subsections, and Marsh does not specify with which regulation therein Genentech failed to comply. In her response to Genentech’s motion to dismiss, Marsh attempted to clarify, stating that “Plaintiffs allege post-marketing failure to warn” and “21 C.F.R. 201 covers warnings and th erefore, a failure to warn is a failure to comply with 21 C.F.R. 201.” R.15 at 16 (Pl.’s Resp. to Defs.’ Mot. to Dismi ss) (Page ID #100). If Marsh means failure to warn consumers or physicians with an adequate label, th is action does not constitute non-compliance if the FDA has approved the label. If she means failure to “warn” the FDA by reporting new safety information, she is essentially reiterating her allegation of non-compliance with the FDA’s reporting requirements. Section 202 poses a similar problem; that section governs adve rtising, which, like the regulations governing postmarketing reporting, does not go to the issue of whether a drug itself complies with the terms of FDA approval. agree to submit safety update reports as provided for by regulation or as requested by the FDA. If this app lication is approved, I agree to comply with all applicable laws and re gulations that apply to approved applications. . . .”

Id. ¶ 108 (Page ID #27). Such allegations do not fit comfortably within the statutory language requiring compliance for immunity to apply. Marsh’s complaint alleges that Genentechdid not comply with the terms of the FDA approval by failing to update its application or submit safety reports, not that “the drug and its labeling” did notcomply. Mich. Comp. Laws § 600.2946(5); see also Taylor , 658 N.W.2d at 129–30 (explaining that the Act limits a manufacturer’s liability when “the drug at issue was . . . labeled in compliance with FDA standards”). Put another way, the statutory language suggests that immunity requires substantive compliance with FDA approval, but Marsh essentially alleges procedural non-compliance. Marsh does not allege that the dose of Raptiva she received was adulterated or that its label varied from the label that the FDA approved. 7
Moreover, failure to submit reports to the FDA that the FDA requires is arguably a species of fraud on the agency under the state Act. Indeed, the Michigan Act’s fraud exception specifically encompasses at least some of the misconduct Marsh alleges—a manufacturer “[i]ntentionally withhold[ing] fr om . . . the [FDA] information concerning the drug that is required to be submitted under the [FDCA]” when the FDA “would haveNos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 10

8 The district court interpreted Marsh’s argument as an allegation of fraud. Marsh’s contention on appeal that the district court ignored the Act’s requirement of compliance with the FDA’s approval or held that immunity does not apply only if non-compliance was intentional rather than negligent stems from a misreading of the district court’s opinion. The di strict court never held that a drug’s compliance with FDA approval is not a condition precedent to immunity for the manufacturer under the Act, but instead concluded that Marsh was not alleging non-compliance. Nor did the district court hold that only intentional fraud, rather than negligence, could result in a finding of non-compliance. Such a holding would be incorrect. Because the district court did not believe that the non-compliance element was implicated, however, its ruling did not address wh at is required for a showing of non-compliance.
9 Because the only alleged act of non-compliance in this case is the manufacturer’s failure to comply with generally applicable requirements of disclosure to the agency, we take no position as to whether an allegation of substantive non-compliance that is unique to the terms of approval of a particular drug or that more directly involves a consumer, such as a chemical variance or an inaccurate label, would be preempted under Garcia

. We also note that, as in Garcia , a claim of non-compliance based on failure to submit safety withdrawn approval for the drug if the info rmation were accurately submitted.” Mich. Comp. Laws § 600.2946(5)(a). 8
If Marsh’s allegations do constitute non- compliance within the meaning of the Act, her “claim” that immunity does not appl y triggers the same concerns that animated Buckman and Garcia . Marsh alleges that Genentech failed to submit updated safety information to the FDA as required of all applicants by FDA Form 356h and generally applicable FDA regulations, and thus relies on “federal enactments [a]s a critical element in [her] case.” Buckman , 531 U.S. at 353. Moreover, this alleged wrong was perpetrated upon the agency, and thus implicates the “inherently federal” relationship described in Buckman

. Id. at 347. Finally, Marsh’s suit would require a court to rule on the adequacy of Genentech’s post-marketing disc losures to the FDA, which is the kind of “inter-branch[]meddling” that concerned the Court in Buckman

. See Garcia , 385 F.3d at 966. The FDA regulates post-marketing reporting, requiring manufacturers to report, inter alia, “adverse drug experience information,” 21 C.F.R. § 314.80(c), and “significant new information . . . that might affect the safety, effectiveness, or labeling of the drug product,” id. § 314.81(b)(2)(i). The FDA also has the discretionary authority to withdraw approval of a drug based on failure to submit these reports. Id. §§ 314.80(j), 314.81(d). Having a court determine whether any non-disclosed information “‘may reasonably affect the statement of contrai ndications, warnings, precautions or adverse reactions in the draft labeling,’” R.1 at ¶ 108 (Page ID #27) (quoting FDA Form 356h), would both usurp the agency’s role and go beyond the court’s institutional expertise. 9Nos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 11

update reports would not be preempted if the FDA itself had found that the manufacturer had failed to report. The fact that Marsh’s substantive clai ms sound in negligence and strict products liability would not enable her to avoid pr eemption, because so did the claims in Garcia

. Marsh alleges that Raptiva was “defective and unreasonably dangerous,” R.1 ¶ 128 (Page ID #30), but Michigan has concluded th at a drug that is approved by the FDA and is in compliance with that approval is, as a matter of law, “not defective or unreasonably dangerous,” Mich. Comp. Laws § 600.2946(5). Inorder to reach her substantive claim under Michigan law, Marsh must first defeat immunity, and, as noted above, Garcia essentially treats this task as a threshold claim that can be preempted. Although Marsh’s allegations of failure to report are a “claim” against immunity rather than the substantive basis of her tort claim, Garcia conflates the two for preemption purposes; under Garcia , the nature of Marsh’s underlying substantive claim is immaterial to the preemption analysis. Finally, Marsh attests that her claim, like the failure-to-warn claim in Wyeth , complements rather than conflicts with th e FDA’s regulatory regime and thus survives preemption. This argument confuses the validity of her substantive claim with the validity of her argument that immunity does not apply. Marsh is correct that Wyeth preserves a role for state law in post-marketing enforcement of drug safety; as a general matter, FDA approval of a drug label does not preempt a state common-law failure-towarn suit premised on the claim that the FDA-approved label is nonetheless inadequate. See Wyeth , 555 U.S. at 558–59. Absent the Michig an Act’s immunity provision, Marsh could bring such a claim. Wyethdoes not help plaintiffs in Michigan, however. Although preemption principles do not foreclos e state-law failure-to-warn claims once the FDA has approved a drug, Michigan law doe s so. Absent a successful “claim” that immunity does not apply, the Act prevents Mi chigan plaintiffs from recovering on the type of claim brought by the plaintiff under Vermont law in Wyeth

.Nos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 12

C. Affirmative Defense Marsh argues that immunity is an affirmative defense and thus that the district court should have required Genentech to prove that the dose of Raptiva that Marsh received was in compliance with the FDA’s approval when it left Genentech’s control before granting immunity to Genentech. Marsh does not cite any authority for the proposition that immunity under the Act is anaffirmative defense, but we will assume for present purposes that it is. If immunity is an affirmative defens e, a defendant manufacturer would normally bear the burden of proving that the FDA approved the allegedly defective drug and that the drug was in compliance with that approva l when it left the manufacturer’s control. A motion to dismiss can be premised on an affirmative defense, however, if “the plaintiff’s own allegations show that a defens e exists that legally defeats the claim for relief.” 5B Charles Alan Wright, Arthur Miller, Mary Kay Kane & Richard Marcus, Federal Practice & Procedure § 1357 at 713 (3d ed. 2004). Here, Marsh’s complaint quoted the Act’s immunity provision and preemptively alleged non-compliance in order to defeat immunity. After setting forth the allegations that Genentech failed to submit updated safety information, the complaint concludes that “[a]s Raptiva was not in compliance with the United States food and drug administration’s approval at the time it left the control of the Defendant, Mic h. Comp. Laws § 600.2946(5) will not shield the Defendants from liability in this action.” R.1 at ¶112 (Page ID #28) (capitalization omitted). In her response to Genentech’s motion to dismiss, Marsh references these allegations and states that she “has pled that Raptiva was not in compliance with its approval at the time it left Defendants control.” R.15 at 13 (Page ID #97). Although the fact that “the plaintiff merely has anticipated the defendant’s answer and tried to negate a defense he believes his opponent will attempt to use against him” is generally not enough to merit dismissal based on an affirmative defense, 5B Wright & Miller, Federal Practice & Procedure § 1357 at 713, Marsh anticipated the defense of immunity in a way that shows that her response to the defense lacks merit.Nos. 11-2373/ 2385/ 11-2417/ 2419 Marsh et al. v. Genentech et al. Page 13

The complaint makes clear that Marsh could not defeat Genentech’s arguments for immunity.

IV. CONCLUSION The State of Michigan has decided to limit the availability of tort remedies against drug manufacturers. As a federal c ourt sitting in diversity, we are of course required to apply Michigan law. We are also bound by our precedent interpreting that law. Even characterized as non-compliance, Marsh’s “claim” that Genentech is not entitled to immunity under the Act triggers the same concerns that animated Buckman and Garcia —it is premised on violation of federal law, implicates the relationship between a federal agency and the entity it regul ates, and asks the court to assume a role usually held by the FDA—and is thus preem pted. We AFFIRM the judgment of the district court.
