In 2001, DePuy, a wholly-owned subsidiary of Johnson & Johnson (J&J/DePuy), initiated a seeding study called the "Multi-center, Prospective, Clinical Evaluation of Pinnacle Acetabular Implants in Total Hip Arthroplasty" (PIN Study). J&J/DePuy designed this study to develop new business opportunities during the launch of their Pinnacle Hip System (PHS) and generate survivorship data for marketing. This article, the first review of a seeding trial for a medical device, examines internal company documents relating to the PIN Study; the analysis herein focuses on the integrity of J&J/DePuy's research practices in conception, implementation, and analysis. J&J/DePuy violated the study protocol and manipulated data; consented participants in violation of standards protecting human subjects; and did not secure Institutional Review Board approval for all study sites. J&J/DePuy used PIN Study results as the "fundamental selling point" for the PHS. Medical device seeding trials are distinct from previously-documented pharmaceutical seeding trials because companies can profit directly from device sales and because these studies may be the first clinical evaluation of the device (as was the case for the PIN Study). Seeding trials are malleable marketing projects, not rigorous scientific studies. Regulatory bodies, physicians, and others should be vigilant for persuasive marketing accounts disguised as science.
