DAW1033D in Obstructive Sleep Apnea
A Phase 1/2 study testing DAW1033D oral capsule in people with Obstructive Sleep Apnea (OSA), run by Brigham and Women's Hospital at 1 site in United States.
Trial summary
Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. OSA patients show a marked reduction in upper airway (UA) dilator muscle activity at sleep onset and this phenomenon leads to increased collapsibility of UA compared to normal subjects.

About this study
Official title: Effect of DAW1033D on Obstructive Sleep Apnea and Its Phenotypic Traits
Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. OSA patients show a marked reduction in upper airway (UA) dilator muscle activity at sleep onset and this phenomenon leads to increased collapsibility of UA compared to normal subjects. In this protocol the investigators will test the effect of DAW1033D administered before sleep on OSA phenotype traits and OSA severity during sleep.
- Conditions
- Obstructive Sleep Apnea (OSA)
- Being tested
- Placebo oral capsule, DAW1033D oral capsule
- Medical subject headings
- Sleep Apnea, Obstructive

What is being measured
The primary outcome is the main question the study is designed to answer.
Apnea Hypopnea Index (AHI, Events/Hour of Sleep)
Based on previous studies the investigators anticipate that DAW1033D will reduce AHI more effectively in subjects with moderate sleep apnea, and mild to moderate pharyngeal collapsibility. AHI describes the frequency of obstruction of the upper airway during sleep and is commonly used to describe the presence and severity of obstructive sleep apnea.
Measured: 1 night
Secondary outcomes (1)
Collapsibility of the Upper Airway: VPassive
Ventilation when ventilatory drive is relatively low during sleep
Measured: 1 night

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing DAW1033D oral capsule in people with Obstructive Sleep Apnea (OSA), run by Brigham and Women's Hospital 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 1 inclusion and 10 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 25 Feb 2020. 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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 5 Feb 2020). 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?
Apnea Hypopnea Index (AHI, Events/Hour of Sleep) (time frame: 1 night). 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 NCT03383887, 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 25 Feb 2020; AzTrials last refreshed its copy on 28 Oct 2026.
