Study Arms:
- Afamelanotide + NB-UVB: Experimental (Type: EXPERIMENTAL): Subject in this arm will receive both afamelanotide implants (one implant administered every 28 days, 4 implants in total) and NB-UVB light (administered thrice weekly, 72 treatments in total).
- NB-UVB alone: Active Comparator (Type: ACTIVE_COMPARATOR): Subjects in this arm will receive NB-UVB light only (administered thrice weekly, 72 treatments in total).

Based on this trial design, predict the completion outcome and termination type (if applicable).
