Study information
Scientific title
A double-blind, placebo-controlled, pilot study to assess the safety and preliminary efficacy of PSD506 in treatment-naïve or previously treated (washed out) patients with benign prostatic obstruction and lower urinary tract symptoms
Acronym
Study hypothesis
Symptoms of lower urinary tract dysfunction are associated with Bladder Outlet Obstruction (BOO) as a result of Benign Prostatic Enlargement (BPE). The symptoms experienced may be characteristic of OverActive Bladder (OAB) or secondary to Detrusor Overactivity (DO). OAB symptoms may be exacerbated by BOO that results from BPE. Treating the bothersome symptoms of OAB is therefore an important goal for the management of comorbid symptomatic DO and BOO. PSD506 is a novel antimuscarinic agent that is being studied for the treatment of OAB. This study aims to assess the safety of PSD506 in men with Lower Urinary Tract Symptoms (LUTS) and BPE/BOO and an International Prostatic Symptom Score (IPSS) of 8 -19, in line with American Urological Association recommendations.

Drug names
PSD506
Primary outcome measure
To demonstrate the similarity in safety profiles between PSD506 and placebo as assessed by a urodynamic measure of bladder outlet obstruction (BOO).
Secondary outcome measures
1. To measure the change in Post Void Residual volumes (PVR) and other urodynamic parameters
2. To obtain a preliminary assessment of efficacy by measuring the change in International Prostatic Symptom Score (IPSS) from baseline
3. To demonstrate the overall safety of PSD506 in this subject population

13. History of clinically significant liver disease, e.g., hepatitis B
14. Prohibited medications taken within two weeks prior to baseline
15. Concomitant use of any agent that has a significant interaction with CYP3A4 or P glycoprotein (Pgp)
16. Clinically significant abnormalities in laboratory test results (including hepatic and renal panels, complete blood count [CBC], chemistry panel)
17. Participation in an investigational drug or device study within 30 days prior to screening

22. Concomitant disease or condition that could interfere with, or for which the treatment might interfere with, the conduct of the study; or that would, in the opinion of the investigator, pose an unacceptable risk to the subject in this study. This would include, but is not limited to, cancer, alcoholism, drug dependency or abuse, or psychiatric disease
23. Any clinically significant abnormality on 12-lead ECG
