A scientific committee will be constituted to monitor data and overall safety. In Phase II, the same scientific committee is planned to review safety and events (relapse, deaths). No Independent Data Monitoring Committee is foreseen in phase I/II because centres selected to participate are restricted to few centres used to phase I/II management and practices.
