July 2020: A federal judge preliminarily approved the settlement agreement. A final fairness hearing is scheduled for November 17, 2020.

June 2020: Plaintiffs moved for preliminary approval of a settlement agreement that would provide class members with a 30 percent cash refund of the company’s suggested retail price for Prevagen products. Class members with proof of purchase may receive a maximum award of $70 while class members without proof of purchase may receive a maximum award of $12. The company also agreed to stop marketing that Prevagen improves memory without adequate scientific evidence to support such claims or qualifying the advertising claim with a disclaimer. This settlement would resolve seven lawsuits: Collins, Engert, Karanthos, Racies, Spath, and Vanderwerff, as well as one state case Miloro v. Quincy Bioscience.

August 2019: The Vanderwerff case was transferred to a court in the Southern District of New York. (Case No. 19-cv-7582, S.D.N.Y.)

October 2018: The parties agreed to consolidate this case with Spath v. Quincy Bioscience. The lead case will be Vanderwerff. (Case No. 17-cv-784, D.N.J.)

February 2017: A class-action lawsuit was filed against Quincy Bioscience for allegedly falsely representing that Prevagen supplements improve memory and provide cognitive benefits, and that the benefits of Prevagen are clinically proven when such claims are not true and without adequate support to make them. (Vanderwerff et al v. Quincy Bioscience Holding Company, Inc. et al, Case No. 17-cv-784, D.N.J.).
