An interventional study of ASV therapy in Insomnia and Insomnia (Moderate), sponsored by ResMed. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-05-19.
Sponsored by ResMed · Not applicable, Interventional, and Treatment
This will be a single center, prospective study designed to evaluate the effect of adaptive servo ventilation therapy on insomnia severity among patients with moderate to severe chronic insomnia.
The primary objective of the study is to evaluate the effectiveness of adaptive servo ventilation therapy to reduce insomnia severity in primary insomnia patients.
2,722 studies on the registry are indexed under Sleep Initiation and Maintenance Disorders; 726 are open to participants now.
This study's planned enrollment of 25 is below the median of 68 across 2,350 interventional studies indexed under Sleep Initiation and Maintenance Disorders.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Device: ASV therapy
Adaptive servo ventilation (ASV) therapy using ResMed AirCurve 11 device will be used to target potential upper airway resistance and respiratory related arousals in patients with insomnia. The ASV device is approved for the treatment of obstructive sleep apnea, and this will be designated as the investigational device for this study with appropriate labelling.

Change in insomnia severity from baseline to 4 weeks after treatment initiation, as measured by subjective questionnaire
Time frame: 4 weeks after therapy start
Sleep Onset Latency
Change in from baseline to end of treatment in sleep onset time
Time frame: 4 weeks after treatment initiation

Started Mar 2026 (actual). Primary completion is estimated for Dec 2026, 9 months after the start.
Of 78 industry-sponsored interventional studies with no phase under Sleep Initiation and Maintenance Disorders, half reached primary completion within 6 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 23. This study's planned 9 months is above that.
Counting every sponsor, half of 1,285 studies reached it within 15 months; a quarter within 6 and three quarters within 34.
