Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for children and teenagers with Down syndrome and moderate to severe obstructive sleep apnea, meaning breathing stops or gets shallow during sleep. It tests whether oxygen during sleep helps memory and other outcomes.

Age
5.0 to 17.9 years at screening
Sex
All sexes
Disease stage
Obstructive sleep apnea with an obstructive apnea hypopnea index (OAHI) of ≥5/hour. No serious low oxygen levels, meaning oxygen saturation <88% for 5 minutes or drops to 60%.
Earlier treatment
Children who use CPAP well now (> 4 hrs/night; > 70% of nights) cannot join. Children who use extra oxygen long-term during the day or night cannot join.
Biomarker or test result
During a sleep study, oxygen must work well: lowest oxygen saturation >92%, obstructive index falls below 5/hour or by > 50%, CO2 stays under 65 mmHg, and oxygen flow is no more than 3.0 LPM and FiO2 no more than 40 %.

Main reasons for not taking part

  • Oxygen saturation < 90% at rest while awake
  • Heart defect present from birth that has not been repaired
  • Moderate to severe high blood pressure in the lungs treated with oxygen or medicines that widen lung blood vessels
  • Someone smokes in the child's bedroom
  • Large tonsils and adenoids where the child can have surgery to remove them and parents agree to it

The registry criteria, word for word

Who can take part

  • Ages 5.0 to 17.9 years at the time of screening
  • Children with OSA and obstructive apnea hypopnea index (OAHI) ≥5/hour
  • Absence of clinically significant hypoxia defined as oxygen saturation <88% for 5 minutes or episodic desaturation to 60% as these levels would otherwise identify children eligible to routinely receive oxygen
  • Favorable response to oxygen therapy (allowing randomization) will be defined as follows:; Oxygen saturation nadir >92% and; Decrease in obstructive index < 5 / hour or by > 50% from screening PSG; Reaching an optimum oxygen flow which is defined as the flow that achieves the lowest level of AHI with maximum CO2 level less than 65 mmHg observed for 5 consecutive minutes and or an increase in CO2 by less than 15 points above baseline. The above criteria are observed while the patient spends a minimal of 30 minutes in the supine position and at least one cycle of rapid eye movement (REM) sleep; Oxygen flow required does not exceed 3.0 LPM and does not exceed a FiO2 > 40 %
  • Willingness to comply with all study procedures and available for duration of study
  • At baseline the participant attempts to perform the neuropsychological tests

Who cannot take part

  • Moderate to severe pulmonary hypertension requiring treatment with oxygen and or pulmonary vasodilator
  • Individuals who develop alveolar hypoventilation with oxygen as previously defined
  • Children with adenotonsillar hypertrophy who are candidates for adenotonsillectomy and parents agree to the surgery
  • Unrepaired congenital heart disease
  • Other severe chronic diseases determined by their provider as making them poor study candidates
  • Current CPAP use with documented compliance(> 4 hrs/ night; > 70% of nights)
  • Oxygen saturation < 90% at rest during wakefulness
  • Chronic daytime or nighttime use of supplemental oxygen
  • Smoker in the child's bedroom
  • Unable to participate in a PSG
  • Enrolled or planning to enroll in another study that may conflict with protocol requirements or confound results in this trial
  • Documented clinically significant untreated hypothyroidism

About the trial

What the trial wants to find out

The purpose of this study is to assess whether oxygen supplementation during sleep improves working memory and other clinical and patient-reported outcomes among children who have Down Syndrome (DS) with moderate to severe Obstructive Sleep Apnea (OSA).

The 2 groups in the trial

  • Oxygen plus supportive care (OXT)Existing treatment, for comparison

    Nocturnal oxygen therapy plus providing patient with healthy sleep habits materials, healthy diet materials and nasal dilators.

    Treatment: Oxygen

  • Supportive care (SC)No study treatment, for comparison

    Providing patient with healthy sleep habits materials, healthy diet materials and nasal dilators.

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
