About this study

This study is conducted to evaluate the effectiveness of DIC075V on ventricular repolarization in healthy subjects compared to placebo after a single dose of DIC075V administered intravenously (IV) and to evaluate ECG assay sensitivity by evaluating the baseline-adjusted effect of a single oral (PO) moxifloxacin 400 mg dose on ventricular repolarization in healthy subjects compared to placebo. Other secondary objectives are as follows:

  • To evaluate the effect of DIC075V on ventricular repolarization in healthy subjects compared to placebo at the Tmax of diclofenac and hydroxypropyl-β-cyclodextrin (HPβCD).
  • To determine if there is a pharmacokinetic/pharmacodynamic (PK/PD) relationship between the duration of the QTc intervals and diclofenac and HPβCD plasma concentrations.
  • Obtain additional pharmacokinetic (PK) information on diclofenac and HPβCD in healthy subjects.
  • Provide additional safety information.
Read the detailed description

This is a randomized, single-dose, comparative, positive and placebo controlled, 4 period, 4-way crossover study evaluating the effect of DIC075V on QTc intervals in healthy subjects. Two doses of DIC075V are tested and include moxifloxicin as a positive control and normal saline as the placebo arm. On 4 separate occasions separated by at least 72 hours, subjects are given single IV or oral (moxifloxicin) treatments. ECGs are acquired from a continuous Holter monitor and selected timepoints will be evaluated. These ECGs will be 15 seconds in duration and extracted in triplicate. Monitoring will continue for 24 hours with each treatment. The primary ECG endpoint is the baseline-adjusted QTc using the Fridericia correction (QTcF). Secondary endpoints include the baseline-adjusted QTc using the Bazett correction formula (QTcB). In addition, a population-specific regression model will be constructed with QT plotted against RR (the time elapsed between 2 consecutive R-waves). Finally, QT parameters are explored graphically in relation to PK variables Cmax, Tmax and AUC.

What is being measured

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

  1. Time-matched active drug-placebo difference in baseline-adjusted QTc interval

    The primary ECG endpoint is the time-matched active drug-placebo difference in baseline-adjusted QTc interval using the Fridericia correction formula (QTcF). The QTcF is evaluated at the time point where the maximal baseline and placebo-adjusted value is observed. These measurements are consistent with ICH E14 guidance.

    Measured: At -1.5, -1.0, and -0.5 hours (pre-dose), and 5, 10, 15, and 30 minutes (2-min window) and 1, 2, 4, 6, 8, 12, and 23.5 hours (5-min window) on Study Days 1, 4, 7, and 10.

Secondary outcomes (3)
  1. Time-matched active drug-placebo difference in baseline-adjusted QTc interval using the Bazett's correction formula (QTcB) evaluated at the timepoint where the maximum mean baseline- and placebo-adjusted QTcB is observed for each active treatment arm

    Measured: At -1.5, -1.0, and -0.5 hours (pre-dose), and 5, 10, 15, and 30 minutes (2-min window) and 1, 2, 4, 6, 8, 12, and 23.5 hours (5-min window) on Study Days 1, 4, 7, and 10.

  2. Time matched active drug-placebo difference in baseline adjusted QTcF at the subject-specific Tmax or the next available ECG timepoint

    Measured: At -1.5, -1.0, and -0.5 hours (pre-dose), and 5, 10, 15, and 30 minutes (2-min window) and 1, 2, 4, 6, 8, 12, and 23.5 hours (5-min window) on Study Days 1, 4, 7, and 10.

  3. Time-matched active drug-placebo difference in the maximum baseline-adjusted QTcF of each subject at each active treatment period.

    Measured: At -1.5, -1.0, and -0.5 hours (pre-dose), and 5, 10, 15, and 30 minutes (2-min window) and 1, 2, 4, 6, 8, 12, and 23.5 hours (5-min window) on Study Days 1, 4, 7, and 10.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing DIC075V in people with Ventricular Repolarization, run by Hospira, now a wholly owned subsidiary of Pfizer at 1 site 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 23 inclusion and 29 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 24 Jul 2015. 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 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. 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?

Time-matched active drug-placebo difference in baseline-adjusted QTc interval (time frame: At -1.5, -1.0, and -0.5 hours (pre-dose), and 5, 10, 15, and 30 minutes (2-min window) and 1, 2, 4, 6, 8, 12, and 23.5 hours (5-min window) on Study Days 1, 4, 7, and 10.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01812538, which also lists 1 linked publication.

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 24 Jul 2015; AzTrials last refreshed its copy on 27 Oct 2026.
