NEW YORK—A federal judge on Wednesday dismissed a proposed class action lawsuit by consumers who accused Pfizer Inc. of failing to disclose the presence of cancer-causing agents in Chantix before recalling the anti-smoking drug.
U.S. District Judge Denise Cote in Manhattan found no plausible allegations that Pfizer had a duty to disclose that Chantix was contaminated by a type of carcinogen known as a nitrosamine, or was unfit to help consumers quit smoking. She also found no proof that Pfizer’s labels were misleading.
