The number and severity of phototoxic reactions, the type and duration of sun exposure, treatment-emergent adverse events and the use of concomitant medication will be recorded by patients in study diaries between Days 0 and 180. Quality of life will be measured using the DLQI and EPP-QoL at Days 0, 60, 120 and 180. Participants will visit the clinic on Days 60, 120 and 180 for assessments of adverse events.
A subset of patients will be photoprovoked on the lower back and dorsal surface of the hand and the minimal symptom dose (MSD) will be determined on Days 0, 30, 60, 90 and 120.
