A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the Investigator in consultation with the GSK Medical Monitor if required agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.

About this study

Official title: An Open-label, Randomised, Single Dose, Two-way Crossover Pilot Study to Determine the Relative Bioavailability of One 8mg Tablet Formulation of Candesartan Cilexetil (GW615775) Relative to One 8mg Reference Tablet of Candesartan Cilexetil (Atacand) in Healthy Adult Human Subjects Under Fasting Conditions

This will be an open-label, randomized, single dose, two-way crossover study. Each subject will participate in both treatment periods and will receive single oral doses of candesartan cilexetil (GW615775) and reference candesartan cilexetil (ATACAND™); the treatment periods will be separated by a washout period of at least 7 days and no greater than 14 days. This study aims to determine the relative bioavailability of an 8mg test formulation tablet of candesartan cilexetil (GW615775) compared to an 8mg reference tablet of candesartan cilexetil in healthy adult subjects. ATACAND is a registered trademark of the AstraZeneca group of companies.

Secondary outcomes (4)
  1. PK parameters assessed by tmax, %AUCex and t1/2

    PK parameters include: Percentage of AUC(0-infinity) obtained by extrapolation (%AUCex), time of occurrence of Cmax (tmax), terminal phase half-life (t1/2).

    Measured: Pre dose, 0.5 hr, 1 hr, 1.5 hr, 2 hr, 2.5 hr, 3 hr, 3.5 hr, 4 hr, 4.5 hr, 5 hr, 5.5 hr, 6 hr, 7 hr, 8 hr, 10 hr, 12 hr, 16 hr, 24 hr, 36 hr and 48 hr of each treatment period.

  2. Safety and tolerability assessment as assessed by adverse events (AEs)

    Measured: Up to 35 days

  3. Safety and tolerability assessment as assessed by vital signs

    Vital sign measurements will include systolic and diastolic blood pressure, and pulse rate.

    Measured: Up to 35 days

  4. Safety and tolerability assessment as assessed by clinical laboratory values

    Clinical laboratory assessments will include hematology, clinical chemistry, routine urinalysis and additional parameters.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Candesartan cilexetil (GW615775, Test formulation) and Candesartan cilexetil (Reference treatment) in people with Hypertension, run by GlaxoSmithKline at 1 site in India.

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 8 inclusion and 15 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 15 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in India. 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?

Plasma pharmacokinetic (PK) parameters assessed by Cmax, AUC(0-infinity) and AUC(0-t) (time frame: Pre-dose, 0.5 hour (hr), 1 hr, 1.5 hr, 2 hr, 2.5 hr, 3 hr, 3.5 hr, 4 hr, 4.5 hr, 5 hr, 5.5 hr, 6 hr, 7 hr, 8 hr, 10 hr, 12 hr, 16 hr, 24 hr, 36 hr and 48 hr of each treatment period.). 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 15 May 2017.
