简要总结
The primary objective of this study is to assess the safety and tolerance of transurethral photodynamic therapy (PDT) with QLT0074.
Secondary objectives are:
- To determine if transurethral PDT with QLT0074 has a therapeutic effect on benign prostatic hyperplasia (BPH), evaluated by the American Urological Association Symptom Index (AUA SI), urinary flow rate (Qmax), and post-void residual volume (PVR).
- To determine the extent of systemic exposure to QLT0074 following transurethral intraprostatic injection.
- To select up to two transurethral PDT drug-light regimens for further clinical development.
详细描述
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:
- 1 or more subjects in the cohort experience macroscopic urinary bleeding not resolved by Day 14, or
- 2 or more subjects in the cohort experience intolerable urinary pain not controlled with over-the-counter medication by Day 14, or
- 1 or more subjects in the cohort experience any other clinically significant urological adverse event, as judged by the Investigator and confirmed 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).
