Benign Prostatic Hyperplasia (BPH) describes a common medical condition in men over 45 associated with voiding (obstructive) and storage (irritative) lower urinary tract symptoms and is in part related to prostate enlargement and obstruction. The standard medical therapy for this condition includes 5-alpha reductase inhibitors -5ARI (eg dutasteride) or alpha blocker therapy (eg tamsulosin), while the most effective medical therapy for BPH is the combination of these two medications. Approximately 10 to 20% of patients diagnosed with BPH also have either a diagnosis of or symptoms of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) with typical genito-urinary pain and discomfort. This particular subset of patients of BPH patients with prostatitis symptoms pose a therapeutic dilemma. CP/CPPS (organ specific phenotype) is the third most prevalent prostate disease after prostate cancer and BPH. CP/CPPS is very prevalent (3-9% of men) and represents a significant percentage of urology outpatients (3-8% of male outpatient visits)resulting in a major impact on quality of life of patients and economic costs to society. Clinical phenotyping allows for prediction of the patients with CP/CPPS most likely to respond to dutasteride and tamsulosin (age, Lower Urinary Tract Symptoms [LUTS] and prostate related phenotypes [BPH]). It can be estimated that up to 30% of men currently diagnosed with CP/CPPS will include men with co-existing Benign Prostatic Hyperplasia (BPH) We propose to determine the efficacy of JALYN (dutasteride-tamsulosin combination) in the amelioration of prostatitis symptoms in men diagnosed with CP/CPPS who have the following clinical phenotype; age = 45 years, Lower Urinary Tract Symptoms (LUTS), enlarged prostate and Organ (prostate) specific symptoms (eg. BPH and CP/CPPS).

Further study details as provided by Queen's University:

Primary Outcome Measures:
  • Chronic Prostatitis Symptom Index (CPSI) [ Time Frame: 6 months ]
    The primary endpoint will be the mean change in NIH CPSI from baseline in the treated group compared to the mean change in NIH CPSI from baseline in the placebo group at 6 months.

Secondary Outcome Measures:
  • Pain subdomain [ Time Frame: 6 months ]
    Secondary endpoints will include analyses of CPSI subdomains (pain, urinary, quality of life)

  • IPSS [ Time Frame: 6 months ]
    International Prostate Symptom Score changes (IPSS)from placebo

  • GRA [ Time Frame: 6 months ]
    Seven point Global Response Assessment (GRA) where responders will be defined as those who report a moderate or marked improvement.

  • Urinary subdomain [ Time Frame: 6 months ]
    Secondary endpoints will include analyses of CPSI subdomains (pain, urinary, quality of life)

  • Quality of Life subdomain [ Time Frame: 6 months ]
    Secondary endpoints will include analyses of CPSI subdomains (pain, urinary, quality of life)

Other Outcome Measures:
  • Safety [ Time Frame: 6 months ]
    Examination of AE and SAEs numbers

  Show Detailed Description


Ages Eligible for Study:   45 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Men will be eligible for the study if:

  1. age at least 45 years
  2. report symptoms of discomfort or pain in the pelvic region during at least 3 of the previous 6 months
  3. total score of at least 12 (out of 43) points on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) at both a screening and randomization visit
  4. IPSS score of at least 8 points 5 tenderness on light palpation of the prostate

6. prostate size estimated to be at least 30cc on digital rectal examination

Exclusion Criteria:

Participants are excluded if

  1. prior treatment with dutasteride or finasteride. Alpha blocker therapy within 3 months of randomization.
  2. documented urinary tract infection (>105 colony forming units per ml of a recognized uropathogen)
  3. history of renal failure (or calculated creatinine clearance of < 60 ml/min)
  4. symptomatic genital herpes in the last 3 months.
  5. unilateral orchalgia without pelvic symptoms
  6. a history of active urogenital cancer
  7. active urethral stricture.
  8. surgery of the lower urinary tract (not including simple diagnostic cystoscopy) in the previous 6 months (including TURP, bladder neck incision, bladder tumor resection, urethrotomy).
  9. History of alcohol abuse
  10. neurologic disease affecting voiding or the bladder
  11. Psychiatric condition that would make it difficult (in opinion of investigator) for patient to participate in the study
  12. Other acute or chronic medical condition that would make it difficult (in opinion of investigator) for patient to participate in the study
