Industry Relationships

Cleveland Clinic physicians and scientists collaborate with industry to advance medical breakthroughs. These partnerships help commercialize discoveries for public benefit while maintaining scientific integrity. To ensure transparency and minimize potential bias, Cleveland Clinic reviews these relationships and publicly discloses when physicians/scientists receive significant compensation for consulting, serve in fiduciary roles, receive royalties, or hold equity interests related to their work. We manage potential conflicts through approval processes, annual reporting, and targeted management plans.

In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers' discoveries to the public, but can present the potential for conflicts of interest related to their research activities.
