CDRH says it is undertaking research efforts to address scientific knowledge gaps in host responses to an implanted metal device, including adverse events, factors that help identify at-risk patients and tests or methods to better predict or identify exaggerated immune responses in patients. The research could also lead to additional actions that may be appropriate to further promote device safety, a Center notice says.  

One research area aims to better understand adverse events associated with metallic implants, particularly whether the events are tied to any specific metal alloy or the device characteristics. It intends to leverage real world clinical data to “identify correlations between patient/device characteristics and clinically manifested sequalae,” the notice says. “The hope is this effort will also provide insight into biological mechanisms that may underlie adverse health outcomes and contribute further to efforts in biomarker discovery and nonclinical test development for more predictive evaluation of device performance in patient subgroups.”

Another research area will aim to “better define the environment surrounding implants in different anatomical locations and use this information to develop more clinically relevant in vitro test methods and safety limits for the release of corrosion and wear debris from metallic devices,” CDRH says. “Evaluating medical devices under clinically relevant test conditions would enable better evaluation of the risks of corrosion and release of wear debris from metallic devices. Improved, clinically relevant safety limits will assist manufacturers in identifying test results which may imply safety concerns associated with a specific metallic device.”
