Study Endpoints

Primary Endpoints

Number of Events of Acute Urinary Retention (AUR) or Benign Prostatic Hyperplasia (BPH)-Related Prostatic Surgery at the Indicated Time Periods.
Years 1, 2, 3, and 4

A participant was considered to have AUR when he was unable to urinate and required bladder catheterization. BPH is also known as an enlarged prostate. When symptoms of BPH become bothersome, surgery may be required. When events of AUR and BPH-related surgery were participant-reported or identified, they were recorded in the participants' clinic record.

Frequently asked questions about dutasteride once daily for 4 years

What is dutasteride once daily for 4 years used for?

Dutasteride once daily for 4 years is a treatment regimen for benign prostatic hyperplasia, also called prostatic hyperplasia, an enlargement of the prostate gland in men. The four-year duration refers to the long-term dosing period studied in a Phase 3 clinical trial in men aged 50 years and older with this condition.

What does dutasteride once daily for 4 years target?

Dutasteride targets the enzymes SRD5A1, SRD5A2, and SRD5A3, which are 5-alpha reductase isoenzymes. It acts as an inhibitor of these targets. By inhibiting all three isoenzymes, the drug blocks conversion of testosterone to dihydrotestosterone, the androgen that drives prostate growth in benign prostatic hyperplasia.

Who makes dutasteride once daily for 4 years?

GSK plc, which trades under the ticker GSK, is the developer of dutasteride once daily for 4 years. The company sponsored the Phase 3 clinical program evaluating this four-year dosing regimen in men with prostatic hyperplasia.

What phase is dutasteride once daily for 4 years in?

Dutasteride once daily for 4 years has been studied in Phase 3 clinical development. It is an investigational long-term dosing regimen rather than a separately approved product, and the Phase 3 trial supporting this four-year regimen has been completed.

What clinical trials is dutasteride once daily for 4 years in?

The regimen was evaluated in the Phase 3 trial NCT00090103, titled Benign Prostatic Hyperplasia Trial With Dutasteride And Tamsulosin Combination Treatment. That completed trial enrolled 4,844 men aged 50 years and older across 37 countries. It was randomized, double-blind, and active-controlled, and it did not select patients by biomarker.
