Defendants manufacture and distribute FDA-approved prescription eye drop medications for treating conditions such as glaucoma. Bottles are pre-packaged with a fixed volume of medication; labeling does not indicate how many doses or days of treatment a patient can extract from the bottle. The dimensions of the bottle’s dropper tip dictate the size of the drop dispensed. Scientific research indicates that a normal adult’s inferior fornix – the area between the eye and the lower eyelid – has a capacity of approximately 7-10 microliters (µLs) of fluid. If a drop exceeding that capacity is placed into an eye, excess medication is expelled, providing no pharmaceutical benefit to the patient. Expelled medication also may flow into a patient’s tear ducts and move into his bloodstream, increasing the risk of certain harmful side effects. These studies conclude that eye drops should be 5-15 µLs. Defendants’ products emit drops that are considerably larger so that at least half of every drop goes to waste. The Third Circuit reversed dismissal of a putative class action (Class Action Fairness Act, 28 U.S.C. 1332) under state consumer protection statutes. The consumers’ allegations of injury were sufficient to confer standing. Plaintiffs claim economic interests in the money they spent on medication that was impossible for them to use; their concrete and particularized injury claims fit comfortably in categories of “legally protected interests” readily recognized by federal courts.

Consolidated appeals involve allegations that the patent-holders for Lipitor and Effexor XR delayed entry into the market by generic versions of those drugs by engaging in a monopolistic scheme that involved fraudulently procuring and enforcing the underlying patents, then entering into a reverse-payment settlement agreement with a generic manufacturer. In 2013, the Supreme Court recognized that reverse payment schemes can violate antitrust laws and that it is normally not necessary to litigate patent validity to answer the antitrust question. The district judge dismissed several claims. The Third Circuit remanded after rejecting an argument that plaintiffs’ allegations required transfer of the appeals to the Federal Circuit, which has exclusive jurisdiction over appeals from civil actions “arising under” patent law, 28 U.S.C. 1295(a)(1). Not all cases presenting questions of patent law necessarily arise under patent law; here, patent law neither creates plaintiffs’ cause of action nor is a necessary element to any of plaintiffs’ claims. Plaintiffs plausibly allege the existence of agreements between the patent holders and the generic manufacturers. The court remanded one of the Lipitor appeals, brought by California pharmacists, and involving claims solely under California law, for determination of whether remand to state court was appropriate. The Lipitor plaintiffs made plausible allegations of fraudulent patent procurement and enforcement, and other related misconduct. View "In re: Lipitor Antitrust Litigation" on Justia Law

Direct purchasers of Wellbutrin XL, a drug for treating depression, sued, alleging that GSK violated the Sherman Antitrust Act by entering into an unlawful conspiracy with Biovail, GSK’s partner in the development of Wellbutrin XL, to delay the launch of generic versions of the drug. Indirect-purchasers asserted similar theories under state law. The purchasers claim that GSK delayed the launch of generic versions by supporting baseless patent infringement suits and a baseless FDA Citizen Petition aimed at generic drug companies and by entering into an unlawful reverse payment settlement agreement with potential competitors. The district court granted GSK summary judgment, finding insufficient evidence that GSK’s patent litigation was a sham or that the settlement delayed the launch of generic Wellbutrin XL. The court granted GSK’s Daubert motion to exclude the testimony of the purchasers’ economic expert; decertified the indirect-purchaser class for lack of ascertainability; dismissed the indirect-purchaser claims brought under the laws of states that were not the home of a named class representative; and denied Aetna’s motion to intervene. The Third Circuit affirmed. After considering the Supreme Court’s 2013 decision, FTC v. Actavis, the court concluded that the purchasers failed to establish a genuine dispute of fact either as to whether GSK engaged in sham litigation or whether GSK’s actions delayed the launch of generic Wellbutrin XL.

In multi-district litigation involving 315 product liability claims, plaintiffs alleged that Pfizer’s drug, Zoloft, a selective serotonin reuptake inhibitor (SSRI), caused cardiac birth defects. The Plaintiffs’ Steering Committee introduced several experts to establish causation. The testimony of each of these experts was excluded in whole or in part. In particular, Nicholas Jewell, Ph.D., a statistician, used the “Bradford Hill” criteria to analyze existing literature on the causal connection between Zoloft and birth defects. The district court conducted a Daubert hearing, excluded Jewell's testimony, and granted summary judgment to defendants, stating that Jewell: “failed to consistently apply the scientific methods he articulates, has deviated from or downplayed certain well-established principles of his field, and has inconsistently applied methods and standards to the data so as to support his a priori opinion.” The Third Circuit affirmed, holding that the district court did not require replication of significant results to establish reliability, but merely made a factual finding that teratologists generally require replication of significant results, and this factual finding did not prevent it from considering other evidence of reliability.
