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.

Appellee was charged with a single count of possession with intent to distribute, or possession, of a “designer drug,” a substance similar to a scheduled controlled substance, not the same. The trial court here determined experts have been unable to reach an agreement on a method for analyzing and determining the similarities between the chemical structures the controlled substance and its designer analogue, leading it to conclude this disagreement rendered the Pennsylvania designer drug statute unconstitutionally vague. The Pennsylvania Supreme Court reversed, finding the common pleas court did not account for the difference between the concepts of analogue and substantial similarity, the latter of which is more readily apprehensible to the lay citizen in the context of comparing chemical structures; nor did it recognize that, unlike the controlled-substance provision, the designer drug provision included a narrowing scienter specification. Moreover, the Court found in this case that there were “considerable similarities” as between the two molecules based on their two-dimensional diagrams. View "Pennsylvania v. Herman" on Justia Law

Apicore owns, and Mylan Is the exclusive licensee of, the 992, 616, and 050 patents, which relate to isosulfan blue (ISB), a triarylmethane dye used to map lymph nodes. The 992 and 616 patents (together, “the process patents”) are directed to a process for preparing ISB by reacting isoleuco acid with silver oxide in a polar solvent, followed by reaction with a sodium solution. In response to Aurobindo’s FDA application to market a generic version of Myland’s drug, Lymphazurin®, Apricore and Myland obtained a preliminary injunction precluding Aurobindo from making, using, selling, offering to sell, and importing the accused ISB product that allegedly infringes the patents. The Federal Circuit affirmed. While the district court’s “equivalents analysis” was deficient and there remains a substantial question concerning infringement, so that the court’s grant of a preliminary injunction based on the process patents constituted an abuse of discretion, the injunction stands under the 050 patent.

The First Circuit affirmed the district court’s dismissal of this putative class action alleging violations under sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The district court concluded that the initial amended complaint failed to meet the heightened pleading requirements of the Private Securities Litigation Reform Act (PSLRA). Thereafter, the court denied Plaintiffs’ subsequent motion to vacate the judgment and for leave to file a second amended complaint to include purportedly new evidence. The First Circuit held, on de novo review, that (1) the initial amended complaint failed to plead particularized facts giving rise to a strong inference of scienter, as required by the PSLRA; and (2) the district court did not abuse its discretion in denying the motion to vacate the judgment and for leave to file a second amended complaint.

The Supreme Court's opinion in CRST Van Expedited Inc. v. E.E.O.C., 136 S. Ct. 1642, 1646 (2016), effectively overruled Branson v Nott's holding that when a defendant wins because the action is dismissed for lack of subject matter jurisdiction he is never a prevailing party. In this case, Amphastar filed a qui tam action against Aventis under the False Claims Act (FCA), 31 U.S.C 3730, alleging that Aventis obtained an illegal monopoly over the drug enoxaparin and then knowingly overcharged the United States. The district court dismissed the suit based on lack of subject matter jurisdiction. The Ninth Circuit held that Amphastar's allegations were based on publicly disclosed information, and it lacked the direct and independent knowledge needed to be an original source. Therefore, the panel upheld the district court's judgment on the merits. However, the panel held that the district court erroneously concluded that it could not award attorneys' fees, because the FCA's fee-shifting provision contained an independent grant of subject matter jurisdiction and because a party who wins a lawsuit on a non-merits issue is a "prevailing party." The panel remanded for resolution of the attorneys' fees issue. View "Amphastar Pharmaceuticals v. Aventis Pharma" on Justia Law

The Eighth Circuit affirmed the dismissal of relator's False Claims Act (FCA), 31 U.S.C. 3729 et seq., suit based on the public disclosure bar. Relator alleged that CSL Behring conspired with pharmacies to submit false claims to the United States for reimbursement for prescription drugs. The Eighth Circuit concluded that, viewed collectively, the public disclosures provided enough information about the participants in the scheme to directly identify the defendants and the subject drugs; the disclosures would have set the government squarely on the trail of the defendants' participation in the purported fraudulent reporting; and the essential elements of relator's claims -- the purported fraud -- were publicly disclosed prior to him filing suit.

The Cervenys sued the manufacturer of Clomid (Aventis, Inc.), asserting various tort claims under Utah law: failure to warn under theories of strict liability and negligence, breach of implied warranty, negligent misrepresentation, and fraud. They presented two theories, pointing to two types of warning labels that Aventis had allegedly failed to provide: (1) a label that warned of risks to the fetus when a woman takes Clomid before becoming pregnant; and (2) a label that unmistakably warned about harm to the fetus when Clomid is taken during pregnancy. The district court rejected the Cervenys’ claims based on preemption. The Tenth Circuit held that the district court ruling was correct on the Cervenys’ first theory, because the undisputed evidence showed that the FDA would not have approved a warning about taking Clomid before pregnancy. But on the second theory, the Tenth Circuit found the district court did not explain why a state claim based on the FDA’s own proposed language would be preempted by federal law. The district court also erred in failing to distinguish the remaining claims (breach of implied warranty, negligent misrepresentation, and fraud) from the failure-to-warn claims. These claims are based at least partly on affirmative misrepresentations rather than on a failure to provide a warning. The district court failed to explain why claims involving affirmative misrepresentations would have been preempted. View "Cerveny v. Aventis, Inc." on Justia Law

Qui tam relator failed to satisfy the False Claims Act’s materiality requirement in alleging that the manufacturer of a widely-prescribed cancer drug, Avastin, suppressed data that caused doctors to certify incorrectly that Avastin was “reasonable and necessary” for certain at-risk Medicare patients. Avastin is FDA-approved and has accounted for $1.13 billion a year in Medicare reimbursements. The relator, formerly the head of healthcare data analytics for the manufacturer, claimed the company ignored and suppressed data that would have shown that Avastin’s side effects for certain patients were more common and severe than reported and that such analyses would have required the company to file adverse event reports with the FDA, and could have resulted in changes to Avastin’s FDA label. He claimed the company caused physicians to submit Medicare claims that were not “reasonable and necessary.” The Third Circuit affirmed dismissal of the claim, stating the allegations may be true but a False Claims Act suit is not the appropriate way to address them. The manufacturer followed all pertinent statutes and regulations. If those laws and regulations are inadequate to protect patients, it falls to the other branches of government to reform them.

The Leahy-Smith America Invents Act did not change the statutory meaning of “on sale” under 35 U.S.C. 102, in a case involving patents that were ready for patenting and subject to an invalidating contract for sale prior to the critical date of January 30, 2002. Teva had invoked the provision as a defense in a suit charging infringement based on Teva’s filing of an Abbreviated New Drug Application (ANDA). The district court upheld, as valid, Helsinn’s patents, directed to intravenous formulations of palonosetron for reducing chemotherapy-induced nausea and vomiting, and rejected Teva’s “on sale” defense. In reversing, the Federal Circuit noted that the invention worked for its intended purpose, that the evidence that the formulation was ready for patenting was “overwhelming,” and that there was no tenable argument that, before the critical date, Helsinn was unable to file a patent application that met the requirements of 35 U.S.C. 112. The district court clearly erred by applying too demanding a standard. The completion of Phase III studies and final FDA approval are not pre-requisites for the invention here to be ready for patenting. View "Helsinn Healthcare S.A. v. Teva Pharmaceuticals USA, Inc." on Justia Law

Serena Kwan appealed the dismissal of her second amended complaint for failing to state a claim upon which relief can be granted. In 2014, Kwan, On Behalf of Herself and All Others Similarly Situated, filed a class action against Defendants-Appellees, SanMedica International, LLC (“SanMedica”), and Sierra Research Group, LLC (“Sierra”), alleging violations of California’s Unfair Competition Law (“UCL”) and California’s Consumers Legal Remedies Act (“CLRA”). The complaint was based on an allegation that the defendants falsely represented that their product, SeroVital, provided a 682% mean increase in Human Growth Hormone (“HGH”) levels, that it was clinically tested, and that “peak growth hormone levels” were associated with “youthful skin integrity, lean musculature, elevated energy production, [and] adipose tissue distribution." The Ninth Circuit concluded the district court correctly concluded that California law did not provide for a private cause of action to enforce the substantiation requirements of California’s unfair competition and consumer protection laws. Further, the district court did not err in concluding that Kwan’s second amended complaint failed to allege facts that would support a finding that SanMedica International’s claims regarding its product, SeroVital, were actually false. Accordingly, the Court affirmed dismissal. View "Kwan v. Sanmedica Int'l" on Justia Law
