入选标准
- •Signed informed consent obtained before any trial-related activity is performed

- •Moderate to severe LUTS at screening, as defined by International Prostate Symptom Score (IPSS) ≥13
- •An IPSS QoL score of ≥3 at screening
- •Prostate specific antigen (PSA) at screening ≤10 ng/mL (responsibility of the Investigator to rule out prostate cancer when PSA is >4 ng/mL, except in the USA where patients with a PSA >4 and ≤10 ng/mL should undergo a prostatic biopsy or have a negative prostatic biopsy within 12 months prior to participation in the trial)
- •Maximum urinary flow (Qmax) ranging between 5 to 15 mL/second with a minimum voided volume >125 mL at screening
排除标准
- •Post void residual volume (PVR) >250 mL
- •Stone in the bladder or urethra causing symptoms
- •Acute or chronic prostatitis
- •Interstitial cystitis / painful bladder syndrome
- •Acute or recurrent urinary tract infections
- •History of acute urinary retention (AUR)
- •Lower urinary tract instrumentation (including prostate biopsy) within 30 days of dosing at Visit 2
- •Clinical evidence of any of the following urinary tract conditions:
- •Mullerian duct cysts
- •Atonic, decompensated, or hypocontractile bladder
- •Detrusor-sphincter dyssynergia (contraction of the detrusor without sphincter relaxation)
- •History of any of the following pelvic conditions:
- •Pelvic surgery or any other pelvic procedure, including radical prostatectomy, pelvic surgery for removal of malignancy, or open lower colonic or rectal surgery
- •Pelvic radiotherapy
- •Any prior surgical procedure of the urinary tract, including minimally invasive LUTS/BPH therapies
- •Lower tract malignancy or trauma
- •Clinically significant microscopic haematuria at screening
- •History of significant renal insufficiency, defined as receiving renal dialysis or having an estimated creatinine clearance <30 mL/minute at screening
- •Systolic blood pressure >180 or <90 mmHg or diastolic blood pressure >110 or <50 mmHg at screening or malignant hypertension
- •Any causes other than BPH, which may affect evaluation of symptoms of urine flow (e.g. neurogenic bladder, bladder neck contracture, urethral stricture, and bladder malignancy) as judged by the Investigator
- •Use of any prohibited therapies
- •Elevated liver function tests at screening:
- •Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) >2 times the upper limit of normal
- •Total bilirubin >1.5 times the upper limit of normal

- •History or current evidence of drug, alcohol, or substance abuse within 6 months prior to screening
- •Hypersensitivity towards any component of the investigational medicinal product (IMP)
- •Previous participation in any degarelix trial

主要结局
Mean Change in International Prostate Symptom Score (IPSS)
时间窗: From Baseline to Month 3 after Dosing
This outcome measure was used to assess the dose-response of the 3 degarelix dose groups in terms of severity of lower urinary tract symptoms (LUTS) and progress of the disease process, versus the placebo group. One treatment month equals 28 days. The IPSS questionnaire is a tool commonly used to assess the severity of LUTS, and to monitor the progress of the symptoms during treatment. It contains 7 questions regarding incomplete emptying, frequency, intermittency, urgency, weak stream, straining, and nocturia. Each question is assigned a score of 0-5 (i.e. minimum total score is 0 and the maximum score is 35), where "0" corresponds to a response of "not at all" for the first six symptoms and "none" for nocturia, and "5" corresponds to a response of "almost always" for the first six symptoms and "5 times or more" for nocturia. The IPSS also includes a question to evaluate a patient's quality of life in relation to his urinary symptoms, which is not included in the total IPSS score.
次要结局
- Mean Change in IPSS(From Baseline to Month 4, Month 5 and Month 6 after Dosing)
- Mean Change in Maximum Urinary Flow (Qmax)(From Baseline to Month 3 and Month 6 after Dosing)
- Mean Percentage Change in Total Prostate Volume (TPV)(From Baseline to Month 3 and Month 6 after Dosing)
- Odds Ratio (as Compared to Placebo) of Treatment Response in IPSS(At Month 3, Month 4, Month 5 and Month 6 after Dosing)
