“Safe and Effective,” Without More, Does Not Warrant Unqualified Safety and Efficacy

The Third Circuit in In re: Avandia Marketing Sales Practices & Products Liability Litigation recently refused to revive a putative class action accusing GlaxoSmithKline PLC (“GSK”) of violating an express warranty allegedly contained on the label of its diabetes drug, Avandia, which declared the drug “safe and effective.” In so doing, the Court reaffirmed the narrow scope of a breach-of-express-warranty claim under New Jersey law and the requirements necessary to sustain such a claim.
