Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a phase 2 study to evaluate the safety and effectiveness of light-activated talaporfin sodium in patients with LUTS due to benign prostatic hyperplasia (BPH).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

4. Patients who understand and have the ability to sign written informed consent prior to any study procedures and/or discontinuation of exclusionary medications;
5. Patients with an International Prostate Symptom Score of ≥ 15 points;
6. Patients with moderate to severe BPH (Bother Score ≥ 3);
7. Maximum urinary flow rate (Qmax) ≤ 15 mL/sec;
8. Post void residual volume (PVR) ≤ 300 mL;
9. Length of prostatic urethra ≥ 4.0 cm.

Exclusion Criteria

17. Patient has an interest in future fertility.
18. Patients with prolonged QT interval at baseline and/or who are currently taking medication that prolongs QT interval ("prolonged QT interval" defined as \> 450 ms).
19. Inadequate organ function as evidenced by the following: Platelet count \<100,000/mm3; WBC \<4,000/mm3; Neutrophils \<1,800/mm3; Hemoglobin \<10 g/dL; AST and ALT \>3 x ULN; Creatinine \>1.5 x ULN
20. Known sensitivity to porphyrin-type drugs or known history of porphyria.
