UNITED STATES DISTRICT COURT EASTERN DISTRICT OF LOUISIANA

STEPHANIE FULLER, ET AL. CIVIL ACTION

VERSUS No. 20-1675

EISAI INC., ET AL. SECTION I

ORDER & REASONS Before the Court are the defendants, Eisai, Inc.’s (“Eisai”) and Arena Pharmaceuticals, Inc.’s (“Arena”), motions1 to dismiss, pursuant to Federal Rule of Civil Procedure 12(b)(6), counts two, three, and four of the plaintiffs’ amended complaint2 for failure to state a claim. The plaintiffs oppose3 the motions, to which the defendants filed replies.4 For the following reasons, the motions are granted in part and denied in part. I. BACKGROUND Stephanie Fuller (“Fuller”) and Robert Fuller5 (collectively, “the plaintiffs”) filed this lawsuit against Eisai and Arena for distributing and manufacturing the

1 R. Doc. No. 26 (Eisai motion to dismiss); R. Doc. No. 27 (Arena motion to dismiss); see R. Doc. No. 27-1, at 1 (stating that Arena “fully joins and adopts the law and arguments set forth in the Memorandum in Support of Defendant Eisai Inc.’s Rule 12(b)(6) Motion to Dismiss Plaintiffs’ Amended Complaint In Part”). 2 R. Doc. No. 20. 3 R. Doc. No. 28. 4 R. Doc. Nos. 32, 34. 5 Robert Fuller, Stephanie’s spouse, alleges a claim for loss of consortium due to Stephanie’s alleged injuries. R. Doc. No. 20, at 1 ¶ 3. The Court refers only to Stephanie when it uses the shorthand “Fuller” herein. supplemental weight-loss drug Belviq, which Fuller used for approximately two months in 2018.6 Fuller claims that Belviq caused her to develop breast cancer.7 As relevant here, the plaintiffs brought three claims under the Louisiana

Products Liability Act (“LPLA”), alleging that the defendants: (1) defectively designed Belviq, (2) defectively manufactured the Belviq doses consumed by Fuller, and (3) breached an express warranty regarding the safety and effectiveness of Belviq.8 Much of the plaintiffs’ allegations relate to what the defendants learned about Belviq throughout its testing and approval process with the Food and Drug Administration (“FDA”). The following is an overview of those allegations as set forth in the amended

complaint, which the Court accepts as true for purposes of deciding the present motions. A. Initial Testing of Belviq & the FDA’s Initial Denial In the first stage of testing, before seeking FDA approval, the defendants conducted two cancer-risk studies on Belviq: one on rats,9 and the other on mice.10 The rat study identified Belviq as a potential carcinogen—at least among rats.11 In

6 R. Doc. No. 20, at 3 ¶ 15. 7 Id. at 2–3 ¶¶ 10–11. Plaintiffs also allege that Fuller suffers from pain and anguish, “diminished enjoyment of life,” and “fear of developing any of the above[-]named consequences.” Id. at 3 ¶ 10. Plaintiffs state that Fuller began to “suffer from breast cancer on or about June 19, 2019.” Id. at 3 ¶ 16. 8 Id. at 17, 20, 22. The plaintiffs also bring an inadequate warning claim, id. at 15, and a claim for Robert Fuller’s loss of consortium, id. at 24, neither of which are challenged by the defendants’ instant motions. 9 Id. at 7 ¶ 52. 10 Id. at 8 ¶ 56. 11 Id. at 7 ¶ 52. particular, the rat study found an increase in “mammary tumors” in both sexes.12 The mouse study produced similar results.13 The plaintiffs argue that, because of these studies, the defendants had “notice” that Belviq could cause cancer in

humans.14 But, as discussed below,15 a pathology working group later reexamined these studies and found that the results were less conclusive than initially thought. The defendants also conducted two human studies between 2006 and 2009, which examined Belviq’s efficacy in reducing body weight.16 These studies “revealed only a 3.3% mean weight loss after one year with [Belviq] over that of the placebo group.”17 And from 2007 to 2010, the defendants conducted a third trial focused on

Belviq’s efficacy among patients with diabetes.18 This third trial, published in 2012, indicated a 3.1% mean weight loss with Belviq over that of the placebo group.19 The plaintiffs argue that these studies prove Belviq’s ineffectiveness as a weight-loss drug. Examining these studies, an FDA advisory committee voted 9-5 against Belviq’s approval, explaining that “the potential benefits did not outweigh the potential risks based on concerns about the preclinical carcinogenicity findings . . .

12 Id. 13 Id. at 8 ¶ 56 (noting that the mouse study “demonstrated an increase in [cancer] in males and . . . females”). 14 Id. at 8–9 ¶ 57. 15 See infra notes 23–27 and accompanying text. 16 Id. at 9 ¶ 58. 17 Id. at 9 ¶ 60. 18 Id. at 10 ¶ 66. 19 Id. and marginal weight loss demonstrated by the clinical trials.”20 In October 2010, the FDA issued a final rejection of Belviq.21 The FDA’s Complete Response Letter stated the reasons for the rejection: “uncertainty in diagnosis of mammary masses in rats,”

the causal link between Belviq and “mammary adenocarcinoma,” and “marginal weight loss results.”22 As explained next, however, the FDA reversed its position and approved Belviq based on a reexamination of the rat study described above. B. The FDA’s Approval of Belviq The defendants sought to address the FDA’s concerns. They convened a working group to reassess the data collected in the rat study.23 That research

clarified Belviq’s cancer risk: “a decreased number of adenocarcinoma” (i.e., cancer), “and an increased number of fibroadenoma” (i.e., noncancerous tumors), “in both the control and [Belviq] groups.”24 The defendants concluded that Belviq’s cancer risk, to the extent one was previously shown, was a “rodent-specific phenomenon.”25 The plaintiffs allege—without explanation—that the working group’s process was “skewed in favor of . . . a finding that [Belviq] was not a carcinogen.”26 Simultaneously, the plaintiffs also state that the FDA, when later reviewing the

working group’s data, itself “disregarded as irrelevant to [the] risk of carcinoma” (i.e.,

20 Id. at 9–10 ¶ 62. 21 Id. at 10 ¶ 63. 22 Id. The letter also cited a “failure to identify a mode of action and a clear safety margin for brain astrocytoma.” Id. 23 Id. at 10 ¶ 64. 24 Id. at 11 ¶ 68 (emphasis added). 25 Id. at 10–11 ¶ 67. 26 Id. at 11 ¶ 70. cancer) the results relating to “fibroadenoma” (i.e., non-cancerous tumors) in rats.27 In other words, the FDA agreed with the working group—concluding that Belviq’s association with certain tumors in rats was not relevant to Belviq’s cancer risk in

humans. In May 2012, an FDA panel voted eighteen-to-four (with one abstention) that “the benefits of Belviq outweighed the risks for an overweight and obese population.”28 The FDA’s Deputy Division Director, when reviewing the defendants’ renewed application, agreed—finding that “he did not believe Belviq posed a risk for mammary adenocarcinoma in humans.”29 Following FDA approval, Arena, as

manufacturer, and Eisai, as the exclusive distributor, jointly launched Belviq in the United States.30 However, the FDA required the defendants to “conduct six . . . post- marketing studies” on Belviq.31 As discussed next, those studies led to Belviq’s withdrawal from the market. C. Subsequent Testing of Belviq As required by the FDA,32 the defendants conducted a post-marketing trial of Belviq. The trial, published in September 2018, involved 12,000 patients across

several countries.33 Although the trial was conducted to assess Belviq’s
