About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Potential Effect of a Single Oral Dose of Moxidectin on the Cardiac QT Interval of Healthy Volunteers

This study will investigate the effect of a single oral dose of moxidectin on the QT interval associated with moxidectin plasma concentrations.

The effect of moxidectin on other ECG intervals, and on safety, will also be assessed, as will preliminary pharmacokinetics and metabolism

Read the detailed description

Moxidectin is being developed as a treatment for Onchocerciasis (river blindness), a serious, debilitating, disease caused by a parasitic worm, Onchocerca volvulus.

Five dose levels of moxidectin will be administered to healthy volunteers and ECG assessments undertaken at pre-specified pharmacokinetic time points to correlate QT interval with moxidectin concentration in plasma.

Being tested
Moxidectin, Placebo

What is being measured

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

  1. Mean Change From Baseline in QTc Interval (Corrected by Friderica's Formula, dQTcF) Associated With Plasma Moxidectin Concentrations After a Single Dose

    Triplicate 10-second ECG recordings taken 1 minute apart using a Mortara continuous 12-lead digital ECG recorder connected to each subject during the Baseline to 72-hour post dose confinement period. Baseline only and baseline and placebo adjusted changes in QTc interval (corrected using the Friderica formula, QTcF) at each timepoint for each dose level were determined. The mean change from baseline (without and with placebo correction, dQTcF and ddQTcF respectively) at each of the 14 time points was calculated for each dose level. The primary outcome measure was the mean dQTcF for all subjects(the dQTcF gradient). The mean dQTcF for each active treatment group was determined at each post dose timepoint but the mean dQTcF by dose level was not calculated. The mean dQTcF at approximate moxidectin Tmax (hour 3 or hour 4) for each active treatment group and at hour 3 for the placebo group is reported.

    Measured: Baseline (pre-dose) and 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48, 60, and 72 hours post dosing

Secondary outcomes (1)
  1. Concentrations of Moxidectin in Plasma

    Concentrations of moxidectin in plasma were assessed by collection of plasma samples at pre-specified intervals after oral dosing with moxidectin. The concentration of moxidectin was determined using a validated LC MS/MS method.The pharmacokinetic time points coincided with ECG collection timepoints (within 5 minutes and no later than 10 minutes after ECG recordings). Plasma PK parameters were estimated from the concentration measurements, including maximum concentration (Cmax) for each individual and mean for each dose cohort.

    Measured: Pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 12*, 24, 36, 48, 60, and 72 hours and days 8,15 and 22 post dosing

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Moxidectin in people with QT Effects in Healthy Volunteers, run by Medicines Development for Global Health 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 4 inclusion and 21 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 14 Mar 2019. 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?

Yes. Results are posted in the registry (first posted 14 Mar 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Mean Change From Baseline in QTc Interval (Corrected by Friderica's Formula, dQTcF) Associated With Plasma Moxidectin Concentrations After a Single Dose (time frame: Baseline (pre-dose) and 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48, 60, and 72 hours post dosing). 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 NCT03012828, 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 14 Mar 2019.
