[Access to medicines for rare diseases: regulatory aspects and public health priorities.]

The legislation on rare diseases has developed in different directions, and drug legislation has undoubtedly played a major role in terms of the results achieved. However, orphan drugs enter the market with a high price, which increasingly represents a problem of sustainability for health systems but notwithstanding Italy shows a high ratio between the level of social protection and access times. In this perspective, it is necessary to be provided with tools for a better system balance with a view to optimize these timeframes. Introducing in Italy a system for tracking the negotiation process that considers the clock stops as the EMA does, would allow to know at what point the negotiation process is. In addition, once the 100-day period is over (net of any clock stops) and in case of failure to reach a negotiation agreement, a second 60-day negotiation round could be proposed and so on. In this way, all the parts involved the system would have a clear scope of action to conclude the process in a flexible but certain timeframe. In this regard, the joint clinical assessments foreseen by the new HTA Regulations provide an additional opportunity to harmonize central decisions with national requirements.
