About this study

Official title: A Phase 3 Open Label Continuation Protocol of a Fixed Dose Combination of Aroxybutynin and Atomoxetine (AD109) in Obstructive Sleep Apnea

The combination drug composed of aroxybutynin and atomoxetine, designated AD109, is being developed by Apnimed for the treatment of obstructive sleep apnea (OSA). The present study is a Phase 3 open label continuation protocol enrolling qualifying participants who completed one of the parent Phase 3 double-blind placebo-controlled studies, APC-APN-304 or APC-APN-305.

What is being measured

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

  1. Number of Participants With Adverse Events (AES) and Serious Adverse Events (SAEs)

    An AE is any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study treatment. An SAE was an AE during any study phase that fulfills one or more of the following criteria: results in death, life threatening (The term 'life-threatening' in the definition of 'serious' refers to an event in which the participant was at risk of death at the time of the event. It does not refer to an event, which hypothetically might have caused death, if it were more severe), requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity.

    Measured: through study completion, an average of 1 year

  2. Number of Participants With Vital Signs Abnormalities

    Vital signs that are planned to be assessed include parameters such as weight,heart rate and systolic and diastolic blood pressure.

    Measured: through study completion, an average of 1 year

  3. Number of Participants With Concomitant Therapy (Medication or Devices)

    Concomitant therapy with devices (i.e., CPAP) and concomitant medications are other prescription medications, over-the-counter (OTC) drugs or dietary supplements that a study participant takes in addition to the drug under investigation.

    Measured: through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Aroxybutynin and Atomoxetine in people with OSA, run by Apnimed at 99 sites in 2 countries.

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 2 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: enrolling by invitation, as of the sponsor's last update on 13 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 99 sites in United States, Canada. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Number of Participants With Adverse Events (AES) and Serious Adverse Events (SAEs) (time frame: through study completion, an average of 1 year). The study lists 3 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 13 May 2025.
