About this study
Official title: Phase III, Multicenter, Randomized, Double-blind Clinical Trial to Assess the Efficacy and Safety of the DTT106 in the Treatment of Erectile Dysfunction Associated With Benign Prostatic Hyperplasia
The purpose of this study is to assess the safety and efficacy of the DTT106 in the treatment of erectile dysfunction associated with benign prostatic hyperplasia
Read the detailed description
After being informed about all risks and benefits and giving written informed consent, the subjects will undergo a 7-day screening to determine eligibility. After that, at visit 0 (V0), the subjects will be randomized to either the DTT106 or dutasteride + tamsulosin (0,5 mg + 0,4 mg).
- Being tested
- DTT106, Dutasteride-Tamsulosin
- Medical subject headings
- Prostatic Hyperplasia, Erectile Dysfunction

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in the Erectile Function domain score of the International Index of Erectile Function (IIEF-EF) at the end of treatment, from baseline.
The IIEF (International Index of Erectile Function) is a quantitative measure used in the diagnostic assessment of erectile dysfunction. The IIEF is the sum of the scores assigned to each question, with scores ranging from 1 to 5, where 1=never and 5=always. The questionnaire covers five domains
Measured: baseline and 12 weeks
Secondary outcomes (11)
Change in maximum urinary flow rate (Qmax)
The maximum urinary flow rate (Qmax) will be measured by a flowmeter, compared to the baseline value, at the end of treatment
Measured: baseline and 12 weeks
Decrease in post-void residual volume (PVR)
Change in post-void residual (PVR) volume, measured through prostate ultrasound
Measured: baseline and 12 weeks
Improvement in urinary symptoms.
Change in the total International Prostate Symptom Score (IPSS) in patients.The IPSS relies upon the responses to seven questions regarding urinary symptoms and one question related to the patient's quality of life. Each question about urinary symptoms allows the patient to select one of six responses indicating the severity of the particular symptom. These responses are assigned points from 0 to 5. Consequently, the total score can vary from 0 to 35, with higher scores representing more severe symptoms. A higher score on the IPSS implies a poorer outcome.
Measured: baseline and 12 weeks
Improvement in urinary emptying symptoms
Change in the score of the emptying domain of the IPSS (obstructive symptoms, questions 1, 3, 5, and 6). The IPSS relies upon the responses to seven questions regarding urinary symptoms and one question related to the patient's quality of life. Each question about urinary symptoms allows the patient to select one of six responses indicating the severity of the particular symptom. These responses are assigned points from 0 to 5. Consequently, the total score can vary from 0 to 35, with higher scores representing more severe symptoms. A higher score on the IPSS implies a poorer outcome.
Measured: baseline and 12 weeks
Improvement in urinary storage symptoms.
Change in the score of the storage domain of the IPSS (irritative symptoms, questions 2, 4, and 7). The IPSS relies upon the responses to seven questions regarding urinary symptoms and one question related to the patient's quality of life. Each question about urinary symptoms allows the patient to select one of six responses indicating the severity of the particular symptom. These responses are assigned points from 0 to 5. Consequently, the total score can vary from 0 to 35, with higher scores representing more severe symptoms. A higher score on the IPSS implies a poorer outcome.
Measured: baseline and 12 weeks
Improvement in the participant's quality of life in relation to their urinary condition
Change in the score of the quality-of-life item of the IPSS (IPSS-QoL). The IPSS relies upon the responses to seven questions regarding urinary symptoms and one question related to the patient's quality of life. Each question about urinary symptoms allows the patient to select one of six responses indicating the severity of the particular symptom. These responses are assigned points from 0 to 5. Consequently, the total score can vary from 0 to 35, with higher scores representing more severe symptoms. A higher score on the IPSS implies a poorer outcome.
Measured: baseline and 12 weeks
Improvement in the participant's sexual function
Change in the total IIEF score. The 15-question IIEF Questionnaire is a validated, multi-dimensional, self-administered investigation found to be useful in the clinical assessment and treatment of erectile dysfunction. It examines the four main domains of male sexual function: erectile function, orgasmic function, sexual desire, and intercourse satisfaction. Each question is scored between 0 and 5, resulting in a total score range of 0-75 (higher score = less dysfunction). Higher scores indicate a better outcome.
Measured: baseline and 12 weeks
Improvement in the participant's orgasmic function.
Change in the Orgasmic Function domain of the IIEF (IIEF-OF, questions 9 and 10). The 15-question IIEF Questionnaire is a validated, multi-dimensional, self-administered investigation found to be useful in the clinical assessment and treatment of erectile dysfunction. It examines the four main domains of male sexual function: erectile function, orgasmic function, sexual desire, and intercourse satisfaction. Each question is scored between 0 and 5, resulting in a total score range of 0-75 (higher score = less dysfunction). Higher scores indicate a better outcome.
Measured: baseline and 12 weeks
Effectiveness of the treatment in improving the participant's sexual desire
Change in the Sexual Desire domain of the IIEF (IIEF-SD, questions 11 and 12). The 15-question IIEF Questionnaire is a validated, multi-dimensional, self-administered investigation found to be useful in the clinical assessment and treatment of erectile dysfunction. It examines the four main domains of male sexual function: erectile function, orgasmic function, sexual desire, and intercourse satisfaction. Each question is scored between 0 and 5, resulting in a total score range of 0-75 (higher score = less dysfunction). Higher scores indicate a better outcome.
Measured: baseline and 12 weeks
Effectiveness in improving the participant's satisfaction with sexual relations
Change in the Satisfaction domain of Sexual Intercourse of the IIEF (IIEF-IS, questions 6, 7, and 8). The 15-question IIEF Questionnaire is a validated, multi-dimensional, self-administered investigation found to be useful in the clinical assessment and treatment of erectile dysfunction. It examines the four main domains of male sexual function: erectile function, orgasmic function, sexual desire, and intercourse satisfaction. Each question is scored between 0 and 5, resulting in a total score range of 0-75 (higher score = less dysfunction). Higher scores indicate a better outcome.
Measured: baseline and 12 weeks
Overall satisfaction of the participant regarding their sex life.
Change in the General Satisfaction domain of the IIEF (IIEF-OS, questions 13 and 14). The 15-question IIEF Questionnaire is a validated, multi-dimensional, self-administered investigation found to be useful in the clinical assessment and treatment of erectile dysfunction. It examines the four main domains of male sexual function: erectile function, orgasmic function, sexual desire, and intercourse satisfaction. Each question is scored between 0 and 5, resulting in a total score range of 0-75 (higher score = less dysfunction). Higher scores indicate a better outcome.
Measured: baseline and 12 weeks
