Trial summary

The conventional hypoxic challenge test might not predict 'fitness-to-fly' equally well in all patients. Patients at risk of hypercapnia with supplemental oxygen are not well studied. Read more about this study

About this study

Official title: 'Fitness To Fly' Testing In Children With Neuromuscular Weakness Or Central Hypoventilation: A Feasibility Study

The conventional hypoxic challenge test might not predict 'fitness-to-fly' equally well in all patients. Patients at risk of hypercapnia with supplemental oxygen are not well studied. Th investigators will study children who have either neuromuscular weakness or central hypoventilation and who require nocturnal or intermittent daytime ventilator support.

The study also aims to assess feasibility of a randomised controlled trial (RCT) comparing the standard hypoxic standard test to a modified test designed to better suit children with type two respiratory failure.

Read the detailed description

This study will assess feasibility of pulse oximetry (SpO2), end tidal carbon dioxide (ETCO2) and transcutaneous carbon dioxide partial pressure (TcCO2) measurement during a modified Hypoxic challenge test (HCT) in 12 children with neuromuscular weakness and 12 with central hypoventilation.

What is being measured

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

  1. proof of concept outcome 1

    number of children/infants with SpO2 <90/85%

    Measured: during hypoxic challenge test

  2. proof of concept outcome 2

    number of children with >15 mmHg rise in TcCO2/EtCO2

    Measured: during hypoxic challenge test

Questions about this trial

What is this clinical trial studying?

A study testing Hypoxic challenge test in people with Neuromuscular Diseases and Central Hypoventilation, run by Great Ormond Street Hospital for Children NHS Foundation Trust at 1 site in United Kingdom.

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 3 inclusion and 2 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 8 Dec 2021. 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 Kingdom. 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?

proof of concept outcome 1 (time frame: during hypoxic challenge test). The study lists 2 primary outcomes in all. 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 8 Dec 2021.
