Objectives:
Primary: The primary study objective is to determine a clinical response as assessed by the
Mayo score to low dose PDT in patients with moderate to severe active distal UC.
Secondary: The secondary study objectives are to assess the effect on inflammation and the
safety and tolerability of low dose PDT in patients with moderate to severe active distal UC.
This is a multicenter, open phase II study that will enroll a maximum of 20 eligible patients
with moderate to severe active distal UC. The first 10 eligible patients, the first cohort,
will receive PDT at a 10 Joule per square centimetre (J/cm2) dose intensity. If no clinical
response is observed in the first 7 eligible patients, the study will be stopped due to lack
of efficacy. If at least 1 clinical response is observed in the first 7 patients, the first
cohort will be completed to a total of 10 eligible patients
