In third party payor litigation over prescription medical products, we have often marveled at the causation arguments that plaintiffs have offered and the willingness of some courts to accept collective proof over what really should involve individualized proof. Like here, here and here. (This same dynamic plays out when governmental entities seek reimbursement for such products too.) Usually, though, the plaintiffs allege that the manufacturer’s fraud—under whatever particular statutes or headings it is pursued—was unknown to them during the time for which they seek damages for amounts paid for the product and that the damages stopped once they found out. In Teamsters Local 237 Welfare Fund v. Astrazeneca Pharms. LP, No. 415, 2015, 2016 Del. LEXIS 236 (Del. Apr. 12, 2016), the plaintiff payors were undone by their concession that they knew about the alleged fraud and kept paying for the drug at issue anyway. Based on its self-described common sense analysis, the Delaware Supreme Court affirmed the dismissal for lack of causation without weighing in on the Superior Court’s rejection of causation where individual physicians made individual decisions about what to prescribe. This is a good result, but we are concerned about the implications for the practices of payors who seem increasingly interested in signing up with contingency fee lawyers to sue medical product manufacturers. (In case you were wondering, that was a teaser, designed to get you to read all the way to the end of the post.)
The basic facts are that the plaintiff filed a purported nationwide class action on behalf of third-party payors in Delaware state court in 2004, alleging that the defendant violated state consumer fraud laws by falsely marketing Nexium as being more effective than Prilosec, an older product with allegedly one-half of the same active ingredient per dose. Adding some facts omitted in the opinion, the initial NDA for Prilosec had been approved in 1989 (under the name Losec) and lost exclusivity in 2001, around which time FDA approved the NDA for Nexium, which had an enantiomer (here, the left hand chiral image) of the Prilosec’s active ingredient as its active ingredient. The indications for both drugs were expanded through the years, with Prilosec going over-the-counter in 2015. These drugs together accounted for a large chunk of the prescriptions written for heartburn, gastroesophageal reflux disease, and related complaints. Plaintiffs claimed that the development of Nexium and the marketing campaign after its introduction were designed to get the defendant paid a high price for its newer branded product instead of money going to pay for cheaper generic versions of the older product. They claimed they had been harmed by paying for the Nexium prescribed by physicians for the patients participating in their plans. The same group of lawyers apparently filed other “essentially identical class actions” with different sets of named plaintiffs, including one in Delaware federal court that resulted in the dismissal of a New York consumer fraud claim. Ignoring some history and details much like the plaintiffs ignored the marketing for Prilosec over the last fifteen years and the difference between a racemic mixture and an enantiomer, the Delaware state court action woke up from a long slumber in 2014 with its second amended complaint asserting the same claims the federal court had disposed of a few years before.
The Superior Court first determined that the law of New York, where the named plaintiffs were based, applied instead of the law of Delaware, where the defendant was based, or the laws of thirteen other states. Id. at *9. The court found that plaintiffs had not alleged the causation required for a consumer fraud claim: the “purported chain of causation that runs from the allegedly deceptive advertisements that may have influenced the decisions of individual doctors to prescribe a drug to their patients to causally affect the payer unions in this case is simply too attenuated,” as the doctors would be “presumed to go beyond advertising medium and use their independent knowledge in making medical decisions.” Id. at **9-10. We certainly like this reasoning, which would apply to a bunch of these cases. We also like that the court did not give plaintiffs a fourth chance to frame a complaint that stated a claim.Continue Reading TPPs Fail to Put Their Money Where Their (Litigation) Mouth Is and Lose
