E.3 | Principal inclusion criteria |
1. Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form. 2. Male subjects of 45 years of age and above. 3. Body weight ≥ 50 kg (inclusive). 4. Subject should have been on and agree to continue to stay on a stable dose of BPH treatment with either a) alpha blocker monotherapy or b) alpha blocker + 5 ARI. Subjects on alpha blockers should have started their therapy at least 3 months prior to screening and be on a stable dose at the start of screening. Subjects on a 5-ARI should have started therapy at least 6 months prior to screening and be on a stable dose at screening. 5. Has a history of overactive bladder symptoms (frequency of ≥ 8 micturition episodes per day and urgency episodes of ≥ 3 per day with or without incontinence) while taking pharmacological therapy for at least 2 months to treat LUTS due to BPH. 6. Subject has an IPSS total score of ≥ 8 at Screening and Visit 3 (Baseline). 7. Subject has a prostate-specific antigen (PSA) level < 4 ng/mL, or if ≥ 4 ng/mL but ≤ 10 ng/mL, prostate cancer has been ruled out to the satisfaction of the investigator. 8. Subjects agrees to not participate in another interventional drug or device clinical trial during the study. 9. In the opinion of the investigator, is able and willing to comply with the requirements of the protocol, including completing study questionnaires and the Bladder Diary. 10. At Visit 2 (Run-in) and Visit 3 (Baseline) visits, subject must have both additional qualifications based on the 3-day Bladder Diary period: a) having an average of ≥ 8 but ≤ 20 micturition episodes per day over the 3-day diary period, and (b) having an average of ≥ 3 urgency episodes per day over the 3-day diary period. 11. Subject must have a post void residual (PVR) volume value of < 100 mL at Screening, Visit 2 (Run-In) and Visit 3 (Baseline). 12. At Visit 2 (Run-in) and Visit 3 (Baseline) visits, having at least 2 average nocturia episodes per night based on 3-day Bladder Diary at baseline. Nocturia is defined as waking to pass urine during the main sleep period. |
|
E.4 | Principal exclusion criteria |
1. Subject has a history of 24-hour urine volume greater than 3,000 mL or over 3,000 mL based on 3-day Bladder Diary at Visit 2 (Run-In ) or Visit 3 (Baseline) visits. 2. Has lower urinary tract pathology that could, in the opinion of the investigator, be responsible for urgency, frequency, or incontinence; including, but not limited to, bladder stones, interstitial cystitis, prostate cancer, persistent urethral stricture, urogenital tuberculosis, and urothelial tumor. 3. Has a history of prostate surgery, including minimally invasive transurethral or transrectal procedures, procedural treatments for BPH within 6 months of Screening or has a planned prostate surgery, including minimally invasive prostate procedures, during the study period. Has a previous or planned pelvic radiation, low anterior resections (LAR), or any abdominoperineal resections (APR) during the study period. 4. Has a history of urinary retention requiring an intervention (eg, catheterization) for any reason. 5. Has maximum urinary flow (Qmax) < 5.0 mL/second with a minimum voided volume of 125 mL at Screening and Visit 3 (Baseline). 6. Has a history of or current nocturnal polyuria at Visit 2 (Run-In ) or Visit 3 (Baseline) visits, based on 3-day Bladder Diary. Nocturnal polyuria is defined as more than one third of the total urine output per 24 hours occurring at night time. 7. Has an active or recurrent (> 3 episodes per year) urinary tract infection by clinical symptoms or laboratory criteria (≥ 5 white blood cells [WBC]/hpf with presence of red blood cell [RBC] and/or a positive urine culture, defined as ≥ 10^5 colony forming units [CFU]/mL [ie, 100 × 10^3 CFU/mL] in a single specimen). Subjects diagnosed with a urinary tract infection (UTI) at the Screening Visit may be treated until the infection has resolved. 8. Has an implanted sacral neurostimulation (SNS) or use of any posterior tibial nerve stimulation (PTNS) device. 9. Has uncontrolled hyperglycemia (defined as fasting blood glucose > 150 mg/dL or 8.33 mmol/L or non-fasting blood glucose > 200 mg/dL or 11.1 mmol/L) or, if in the opinion of the investigator, is uncontrolled. 10. Has uncontrolled hypertension (systolic blood pressure of ≥ 180 mmHg and/or diastolic blood pressure of ≥ 100 mmHg) or has a resting heart rate (by pulse) > 100 beats per minute. 11. Subjects who have systolic blood pressures ≥ 160 mmHg but < 180 mmHg are excluded, unless deemed by the investigator as safe to proceed in this study and able to complete the study per protocol; these subjects must be on stable hypertension medication for at least 3 months prior to Screening Visit.
