Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Between 18 to 65 years of age for men and 18-75 for women, inclusive, at the Screening Visit.
  • Mean AHI 10 to 45 events/h, inclusive
  • PGI-S: >1
  • BMI between 18.5 and 38 kg/m2 for men and 40 kg/m2 for women, inclusive.

Exclusion Criteria:

  • Current clinically significant sleep disorder other than OSA
  • Clinically significant craniofacial malformation.
  • Clinically significant cardiac disease (e.g. rhythm disturbances, coronary artery disease or heart failure or hypertension requiring more than 2 medications for control).
  • Participants with a history of using devices for OSA treatment, including CPAP, oral or nasal devices, or positional devices, may enroll as long as the devices have not been used for at least 2 weeks prior to first PSG and are not used during participation in the study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Apnea-Hypopnea Index (AHI4) From Baseline: Combined AD109 Arms vs. Placebo
Time Frame: Baseline (mean of PSG Visits 2 and 3) to Day 21 and Day 28 (PSG Visits 5 and 6)
Change in AHI4 (apnea-hypopnea index, 4% oxygen desaturation criterion; average respiratory events per hour of sleep) measured by in-lab polysomnography. Baseline was the mean of two pre-treatment PSG nights (Visits 2 and 3). Change from baseline was assessed at treatment PSG nights at approximately Day 21 (Visit 5) and Day 28 (Visit 6), modeled as repeated measures, with the reported value representing the model-based LS mean using equal (0.5/0.5) weighting between the Day 21 and Day 28 visits.
Baseline (mean of PSG Visits 2 and 3) to Day 21 and Day 28 (PSG Visits 5 and 6)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
