Since 1973 The INT Ethics Committee reviews all new clinical studies submitted by investigators and previously approved by the Scientific Institutional Review Board.

The Institutional Ethics Committee serves as the reference Committee for Scientific Institutes (IRCCS) of the Lombardy Region. In this capacity, it continued to organize approximately one meeting a month to discuss and share common issues. The Investigator-driven studies, the informed consent process and compassionate use of drugs were the major topics discussed.

In 2015, 200 new studies were submitted to the Ethics Committee for approval: 112 were interventional trials, of which 70 were sponsored by commercial companies and 42 were investigator-driven or sponsored by cooperative groups; 88 were observational, of which 6 were sponsored by commercial companies and 82 were investigator-driven or sponsored by cooperative groups.
