*Please note that from time to time there are minor redactional changes in the protocol (for example, each time the Sponsor adds a new country and therefore a new Head of Steering Committee). When this occurs, the Sponsor only changes the last number of the Protocol. The last substantial amendment made to the Protocol was Version 5.0 (and therefore, the version approved by the ethical committee of the Coordinating Hospital in Italy). Since that approved version of the Protocol, the Sponsor declares to have only made redactional changes to the names of Heads of Steering Committees (5.0.1, 5.0.2, 5.0.3 and so on).
