The primary objective of this study is to assess the safety and tolerance of transurethral photodynamic therapy (PDT) with QLT0074.
Secondary objectives are:

Study Design: | Treatment, Non-Randomized, Open Label, Uncontrolled, Single Group Assignment, Safety/Efficacy Study |
Official Title: | A Phase I/II Dose Escalation Study to Assess the Safety, Tolerability, and Preliminary Efficacy of Transurethral Photodynamic Therapy With QLT0074 for Benign Prostatic Hyperplasia |
This will be a multicenter, uncontrolled, dose escalation, exploratory study in subjects with symptomatic BPH. Six study centers are planned.
Each subject will receive a fixed dose of QLT0074 (0.4 mg) injected transurethrally into the prostate followed by transurethral light application to activate the drug. Five light dose cohorts will be investigated sequentially (25, 50, 80, 120, and 150 J/cm2), with 3 subjects in the first cohort and 6 subjects in cohorts 2-5 for a total of 27 subjects. The follow-up period for each subject is 180 days. There will be a minimum 30-day interval between treatment of the last subject in one cohort (Day 0) and treatment of the first subject in the next cohort to monitor predefined toxicities and ensure safety and tolerance in subjects of the previous cohort.
A Safety Monitoring Committee will evaluate toxicity related to PDT effects, and approve escalation of the light dose for each cohort. The light dose will not be escalated if any of the following predefined toxicity criteria occur and are judged to be related to a PDT effect by the Safety Monitoring
Committee:
In addition to the above events, the Safety Monitoring Committee will evaluate the incidence, timing, severity, and frequency of other adverse events and serious adverse events to assess the safety of transurethral PDT and the treatment procedures (such as the use of the cystoscope, InjectTx device, treatment balloon-catheter, etc).
To prevent treating subjects with a light dose greater than that which already provides substantial clinical benefit, the Safety Monitoring Committee will review preliminary efficacy data (AUA SI scores and Qmax values) after all subjects in a cohort (for each of the first 4 cohorts) have completed the Day 90 visit. Further enrollment will be curtailed if more than 75% of subjects in a cohort experience both of the following efficacy stopping criteria by Day 90:
