Trial summary

The purpose of this study is to evaluate the effects on cardiac repolarisation of supratherapeutic doses of AZD3480 compared to placebo in healthy male volunteers, subgrouped as extensive metabolisers and poor metabolisers according to CYP2D6 metabolic capacity, using moxifloxacin as positive control.

About this study

Official title: A Double-Blind, Randomised, Multicentre, Placebo-Controlled, 4-Ways Crossover Study to Investigate the Effect on the QT/QTc Interval of Repeated and Escalating Doses of AZD3480 During 6 Days, Using Moxifloxacin as a Positive Control, in Healthy Male Volunteers, CYP2D6 Extensive and Poor Metabolisers.

The purpose of this study is to evaluate the effects on cardiac repolarisation of supratherapeutic doses of AZD3480 compared to placebo in healthy male volunteers, subgrouped as extensive metabolisers and poor metabolisers according to CYP2D6 metabolic capacity, using moxifloxacin as positive control.

What is being measured

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

  1. QTcX interval (supratherapeutic doses in comparison to placebo).Subject-specific correction of QT, QTcF and QTcB (supportive outcome variables).Bazett QTcB=QT*RR-1/2Fridericia QTcF=QT'RR-1/3

    Measured: 11 dECG measurements x 4 (4-way crossover)

Secondary outcomes (3)
  1. QTcX (therapeutic doses in comparison to placebo).PR-, QRS-, RR-intervals

    Measured: 11 dECG measurements x 4 (4-way crossover)

  2. Plasma concentration (AUC, Cmax, tmax etc)

    Measured: 11 PK-measurements x 4 (4-way crossover)

  3. Registration of AEs, blood pressure, ECG, clinical laboratory tests

    Measured: From enrolment to follow-up

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AZD3480 and Moxifloxacin in people with Healthy, run by AstraZeneca.

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 2 inclusion and 3 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 25 Sep 2008. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

QTcX interval (supratherapeutic doses in comparison to placebo).Subject-specific correction of QT, QTcF and QTcB (supportive outcome variables).Bazett QTcB=QT*RR-1/2Fridericia QTcF=QT'RR-1/3 (time frame: 11 dECG measurements x 4 (4-way crossover)). 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 25 Sep 2008.
