Study of Light-Activated Talaporfin Sodium in Patients With Lower Urinary Tract Symptoms (LUTS) Due to Benign Prostatic Hyperplasia (BPH)
A Phase 2 Study to Evaluate the Safety and Effectiveness of Using the Litx™ BPH System in Patients With Lower Urinary Tract Symptoms (LUTS) Due to Benign Prostatic Hyperplasia (BPH) Who Are Candidates for Interventional Therapy
Study Overview
Status
Intervention / Treatment
Detailed Description
This is a phase 2 study to evaluate the safety and effectiveness of using light-activated talaporfin sodium in patients with LUTS due to BPH who are candidates for interventional therapy.
The eligible patient will undergo placement of a proprietary drug activator into the prostatic urethra. Following the placement of the drug activator, patients will receive talaporfin sodium at 1 mg/kg intravenously by slow push over 3-5 minutes. Fifteen minutes after injection a light dose of 100 Joules per centimeter (J/cm) will be delivered at 20 mW/cm to each patient for a treatment duration of 1 hour 23 minutes.
SAE reporting will occur from the day of treatment (Day 0) through end of study (month 12), inclusive. Any SAE that is still ongoing at the end of the study will be followed until assessed as chronic, stable or resolved.

- Patients who understand and have the ability to sign written informed consent prior to any study procedures and/or discontinuation of exclusionary medications;
- Patients with an International Prostate Symptom Score of ≥ 15 points;
- Patients with moderate to severe BPH (Bother Score ≥ 3);
