About this study

Official title: An Open-label, Randomized, Single Dose, Three-way Crossover, Six Sequence Pilot Study to Determine the Relative Bioavailability of Candesartan Cilexetil 16mg From Two Candidate Tablet Formulations of GW615775 Relative to One 16mg Tablet of Reference Candesartan Cilexetil in Healthy Adult Human Subjects Under Fasting Conditions

This study will investigate the relative bioavailability of two candidate tablet formulations of 16 milligram (mg) Candesartan cilexetil (GW615775) compared with the reference product ATACAND™ containing 16 mg Candesartan cilexetil in healthy human subjects. This is an open-label, randomized, single dose, three-way crossover, six sequence study enrolling 18 healthy human subjects to ensure at least 14 subjects complete the study as planned. Each subject enrolled will participate in all three treatment periods and will be assigned to one of the six treatment sequences, in accordance with the randomization schedule. The treatment periods will be separated by a washout period of at least 7 days and no more than 14 days between dosing occasions. A follow up visit will be conducted 14-21 days post last dosing. ATACAND is a registered trademark of the AstraZeneca group of companies.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Composite of pharmacokinetic (PK) parameters.

    Pharmacokinetic parameters will be measured to estimate the relative bio-availability following administration of two candidate tablet formulations of Candesartan cilexetil relative to reference Candesartan cilexetil tablet. Pharmacokinetic parameters include: maximum observed concentration (Cmax), area under the concentration-time curve from time zero (pre-dose) extrapolated to infinite time (AUC[0-infinite]), Area under the concentration-time curve from time zero (pre-dose) to last time of quantifiable concentration within a subject across all treatments (AUC[0-t]).

    Measured: PK samples will be collected at pre-dose, 0.5, 1, 1.5, 2, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24, 36 and 48 hours post dose in each treatment period.

Secondary outcomes (4)
  1. Plasma PK profile

    Pharmacokinetic parameters to be estimated include: time of occurrence of Cmax (Tmax), terminal phase half-life (t1/2) and percentage of AUC(0-infinity) obtained by extrapolation (%AUCex).

    Measured: PK samples will be collected at pre-dose, 0.5, 1, 1.5, 2, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24, 36 and 48 hours post dose in each treatment period.

  2. Vital sign assessment as a safety measure

    Vital sign assessment include: blood pressure and pulse rate measurements.

    Measured: Up to 30 days

  3. Number of subjects with adverse events as a safety measure

    Adverse events will be collected from the start of Study Treatment until the subject's final discharge from study at the end of Treatment Period 3, follow-up call or last outpatient visit, whichever is the latest.

    Measured: 50 days

  4. Laboratory parameter assessment as a safety measure

    Laboratory parameters include: hematology, clinical chemistry, urinalysis and additional parameters.

    Measured: Up to 30 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Candesartan Cilexetil in formulation 1, Candesartan Cilexetil in formulation 2 and ATACAND in people with Cardiovascular Disease, 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 16 inclusion and 19 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 12 Mar 2018. 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?

Composite of pharmacokinetic (PK) parameters. (time frame: PK samples will be collected at pre-dose, 0.5, 1, 1.5, 2, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24, 36 and 48 hours post dose in 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 12 Mar 2018.
