What years of registry data add to the trials

Randomized trials prove an effect over months; registries show what happens over years. For EPP, multiple national cohorts have followed afamelanotide patients well beyond the trial windows, and this unit summarizes what they found.

The recurring themes are sustained quality-of-life gains, unusually high continuation rates, and a hint of liver benefit, all pointing in the same direction as the pivotal trials.
