About this study

Official title: Long QT & Hearing Loss Prospective Study Registry

The purpose of this study is to determine the true incidence of long QT (LQT) amongst a large cohort of subjects diagnosed with unilateral (right/left) or bilateral sensorineural hearing loss.

Read the detailed description

The purpose of this study is to determine the true incidence of long QT (LQT) amongst a large cohort of subjects diagnosed with unilateral (right/left) or bilateral sensorineural hearing loss.

The goal of this study is to answer the following questions:

  1. What is the incidence of an abnormal ECG (QTc > 450 msec) in neonates greater than a week of age with either unilateral or bilateral Sensorineural hearing loss?
  2. What percentage of neonates greater than one week of age with either bilateral or unilateral sensorineural hearing loss and an abnormal ECG have an identifiable genetic mutation?
  3. What is the incidence of an abnormal genetic mutation consistent with long QT regardless of the ECG in neonates with bilateral sensorineural hearing loss?

What is being measured

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

  1. The incidence of an abnormal ECG (QTc > 450) in neonates greater than a week of age with either unilateral or bilateral sensorineural hearing loss

    ECG results to determine QTc length

    Measured: 6 months

Secondary outcomes (1)
  1. In neonates > 1 week of age with either bilateral or unilateral sensorineural hearing loss and an abnormal ECG, percentage have an identifiable genetic mutation

    Audiology diagnostic results

    Measured: One year

Questions about this trial

What is this clinical trial studying?

An observational study of Sensorineural Hearing Loss and Long QT Syndrome, run by Pediatrix at 12 sites 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 6 inclusion and 5 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 5 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

The incidence of an abnormal ECG (QTc > 450) in neonates greater than a week of age with either unilateral or bilateral sensorineural hearing loss (time frame: 6 months). 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 NCT02082431, 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 5 Oct 2020.
