Official Title: A Pivotal, Open-label Trial Assessing the Safety and Efficacy of the 0.5 mg Dutasteride and 0.4 mg Tamsulosin Combination Once Daily for Six Months in Patients With Benign Prosta

Brief Summary:

Open-label, 6 month-treatment with the IP in all subjects. - Sample size: A total of 90 subjects will be enrolled so that among them at least 57 will complete the 6-month treatment period and evaluable for analysis.

-Primary objective: To assess the safety of 0.5 mg dutasteride/0.4 mg tamsulosin combination therapy for six month in BPH patients by monitoring category, frequency and severity of adverse events encountered during the treatment period.

-Secondary objective: To assess the efficacy of 0.5 mg dutasteride/0.4 mg tamsulosin combination therapy with regard to symptom improvement in BPH patients by monitoring and analyzing of changes in IPSS and Qmax after 6 months of treatment.


Detailed Summary: Visit 0 or Screening Visit (M0) - D0 + 2): Following tasks will be performed: ICF collection, subject code assignment, physical examination (vital signs, demographic data, medical history); checking of inclusion and exclusion criteria: prostate symptom score according to IPSS, laboratory tests (hematology, blood chemistry, electrolytes, total PSA level, free-to-total PSA ratio, Qmax, urinalysis, transrectal prostate ultrasonography (TRUS), 12-lead electrocardiography (ECG), scoring of Sexual Function Questionnaire (SFQ), concomitant medication assessment, IP dispensing. • Visit 1 (Month 1 (M1) - D30 ± 3): Following items will be recorded: treatment compliance, vital signs, blood chemistry, ECG, adverse events (AEs), concomitant medication; dispensing of new IP doses and collecting of dispensed IP at the last visit. • Visit 2 (Month 2 (M2) - D60 ± 3): Following items will be recorded: treatment compliance, AEs, concomitant medication; dispensing of new IP doses and collecting of dispensed IP at the last visit. • Visit 3 (Month 3 (M3) - D90 ± 3): Following items will be recorded: vital signs, laboratory tests (hematology, blood chemistry, electrolytes, Qmax, urinalysis, 12-lead ECG, total PSA level), concomitant medication, SFQ score, AE assessment, collecting of dispensed IP at the last visit and dispensing of new IP doses. • Visit 4 (Month 4.5 (M4) - D135 ± 3): Following items will be recorded: treatment compliance, vital signs, AEs, concomitant medication; dispensing of new IP doses and collecting of dispensed IP at the last visit. Visit 5 (Month 6 (M6)- D180 ± 3): Following items will be recorded: treatment compliance, vital signs, prostate symptom score according to IPSS, laboratory tests (hematology, blood chemistry, electrolytes, Qmax, urinalysis, 12-lead ECG, total PSA level, free-to-total PSA ratio, TRUS; concomitant medication, SFQ score, AE assessment, collecting of the previous dispensed IPs .

Current Primary Outcome:

  • Number of Participants With Any On-treatment Adverse Events (AEs) or Any Serious Adverse Event (SAEs) and Treatment-related AEs [ Time Frame: From start of study medication until follow-up (up to 7 months) ]
    An AE is defined as any untoward medical occurrence in a participant temporally associated with the use of a medicinal product at any dose, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, is an important medical event that jeopardizes the participants or may require medical or surgical intervention to prevent one of the other outcomes listed in the above definition, and is associated with liver injury and impaired liver function.
  • Number of Participants With Any Post-treatment Adverse Events (AEs) or Any Serious Adverse Event (SAEs) and Treatment-related AEs [ Time Frame: From start of study medication until follow-up (up to 7 months) ]
    An AE is defined as any untoward medical occurrence in a participant temporally associated with the use of a medicinal product at any dose, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product.

    Original Primary Outcome: Use the number of participants with adverse events,serious adverse events and treatment-related adverse events as a measure of Safety [ Time Frame: 6 months treatment and 1 month follow up ]

    Using the catergory,frequency and severity of adverse events,serious adverse events and treatment-related adverse events including abnormalities in heamatology,biochemistry,electrolytes,PSA and ECG encountered during the treatment period.


    Current Secondary Outcome:

    • Change From Baseline in the International Prostate Symptom Score (IPSS) at Month 6 [ Time Frame: Baseline and Month 6 ]
      The IPSS is a screening tool used to assess the symptoms of prostate related disease. The IPSS questionnaire consists of seven symptoms questions including feeling of incomplete bladder emptying, frequency, intermittency, urgency, weak stream, straining and nocturia, each referring to during the last month, and each involving assignment of a score from 0 to 5 (no symptoms to almost always symptoms) for a total of maximum 35 points. IPSS total is the sum of the scores of seven questions; therefore, the possible total score ranges from 0 to 35 (0-7: Mildly symptomatic; 8-19: Moderately symptomatic; 20-35: Severely symptomatic). IPSS was assessed at Baseline and Month 6. Change from Baseline was calculated as Month 6 IPSS score- minus Baseline IPSS score.
    • Change From Baseline in Maximum Rate of Urinary Flow (Qmax) at the Indicated Time Points [ Time Frame: Baseline, Month 3 and Month 6 ]
      The Qmax is used as an indicator for the diagnosis of enlarged prostate. A lower Qmax may indicate that the enlarged prostate. Qmax was assessed at Baseline (screening), Month 3 and Month 6. Change from Baseline was calculated as Qmax score at specified timepoint minus the Baseline Qmax score.


    Original Secondary Outcome: Use changes in International Prostate symptom score (IPSS) and Qmax (Maximum rate of Urinary Flow (ml/sec) as a measure of Efficacy [ Time Frame: 6 months ]

    expect to see a decrease in IPSS and an increase Qmax compared to baseline visit
