Clinical Trial Summary

Investigation of the efficacy and safety of the stable combination of dutasteride and tamsulosin (Dinaplex®) in the Greek population as well as the evaluation of the quality of life of patients with benign prostatic hyperplasia (BPH) in treatment with a stable combination of dutasteride and tamsulosin (Dinaplex®)

Description:

Combination therapy with the 5-α reductase inhibitor, dutasteride, and the α-blocker, tamsulosin, in men with moderate to severe benign prostatic hyperplasia and prostate enlargement, was studied in the Combination of Avodart ™ and Tamsulosin (CombAT) which was a four-year, global, multicenter, randomized, double-blind, parallel design (3 arms) study. The aim of the study was to investigate the benefits of combination therapy (dutasteride-tamsulosin) compared to monotherapy in terms of improvement of symptoms and long-term results (AUR and surgery), in men with moderate to severe BPH. The primary endpoint in the two years since the start of the study was the change in the IPSS score, while the primary endpoint, after four years of treatment, was the time until the long-term results manifested (i.e. AUR or CF surgery) as well as the percentage of participants who were led to them. Patients were at least 50 years old with a prostate tumor ≥30 cm3 and a PSA level ≥ 1.5 ng / mL. 4838 men (39) participated in this study.
