About this study

Official title: An Open-Label, Randomized, Single Dose Three-Period Partial Crossover Study to Determine the Bioequivalence and Food Effect of a Combination Capsule Formulation of Dutasteride and Tamsulosin Hydrochloride (0.5mg/0.4mg) Compared to Concomitant Dosing of AVODART™ 0.5mg and Flomax 0.4mg Commercial Capsules in Healthy Male Subjects

This study will be an open-label, randomized, single dose, three way partial crossover study in healthy male subjects. The aim of the study is to evaluate bioequivalence of a fixed dose combination (FDC) capsule of dutasteride and tamsulosin hydrochloride (HCl) (0.5 milligram [mg]/0.4 mg) relative to co-administration of dutasteride 0.5 mg capsules and tamsulosin hydrochloride 0.4 mg tablets in both the fed and fasted states. Approximately 98 healthy adult male subjects will be enrolled into the study. Subjects will receive single oral doses in 3 treatment periods and be randomized to one of twelve different treatment sequences (ABC, ACB, BAC, BCA, CAB, CBA, ABD, ADB, BAD, BDA, DAB, DBA) wherein A= commercially available tamsulosin hydrochloride 0.4 mg and dutasteride 0.5 mg in a fed state, B= fixed dose combination formulation of dutasteride and tamsulosin hydrochloride (0.5 mg dutasteride, 0.4 mg tamsulosin hydrochloride) in a fed state, C= commercially available tamsulosin hydrochloride 0.4 mg and dutasteride 0.5 mg in a fasted state, D= fixed dose combination formulation of dutasteride and tamsulosin hydrochloride (0.5 mg dutasteride, 0.4 mg tamsulosin hydrochloride) in a fasted state. Each treatment period will be separated by a minimum 28 day washout period. The total duration of a subject's involvement in this study is approximately 15-18 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Treatment sequence A, Treatment sequence B and Treatment sequence C in people with Prostatic Hyperplasia, run by GlaxoSmithKline at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Area under the curve (AUC) from time zero to 24 hours (AUC[0-24]) of plasma tamsulosin in fed state (time frame: Pre-dose and post dose at 1,2,3,4,5,6,7,8,10,12,16,24,36,48,72hrs). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2017.
