BIORESEARCH MONITORING PROGRAM (BIMO) BIMO Program Comprehensive program of on-site inspections and data audits designed to monitor all aspects of the conduct and reporting of FDA-regulated research BIMO Program Objectives • Protect the rights, safety, and welfare of subjects in FDA-regulated trials • Determine the accuracy and reliability of clinical trial data submitted to FDA in support of research or marketing applications; and • Assess compliance with FDA’s regulations governing the conduct of clinical trials, including those for informed consent and ethical review BIMO Inspections • Each FDA Center has oversight of inspections of research related to the product(s) it regulates • Inspections are usually conducted by ORA field investigators – Field inspectors are NOT specifically assigned to CDER – All Field inspectors are responsible for conducting inspections for all centers (CBER, CDER, CDRH, CFSAN, etc.) BIMO Inspections Completed FY09 Center CI IRB Spon/Mon GLP Total CBER
