| Eligibility |
Inclusion Criteria:

Diabetes/Body Mass Index (BMI) • Presence of type 2 diabetes and/or BMI between 27 and 43
kg/m2 for men, or 45 kg/m2 for women, inclusive.
Obstructive Sleep Apnea (OSA) History and Measures
- Home Sleep Apnea Testing (HSAT) criteria ( Mean Respiratory Event Index (REI4)
(Hypopneas defined by 4% oxygen desaturation) of >5 and <45. REI is determined as a
mean number collected across 2 nights of testing initiated at Visit 2; = 25% central
or mixed apneas (as proportion of total apneas and hypopneas)
- Participants with a history of using devices for OSA treatment, including Continuous
Positive Airway Pressure (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
HSAT and are not used during participation in the study.
Weight
- For the subjects in the incretin arm the following criteria must be met (Patients must
have an identified prescriber and adhere to drug labelling considerations; A patient's
individual dose is stable over the past 4 weeks without intention to increase to
decrease dosing based on side effects or efficacy; Willingness to maintain a
medication administration diary during the study.
- The following agents and doses are acceptable to meet inclusion criteria: (
Tirzepatide (Mounjaro®, Zepbound®): doses of 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg, 15mg can
be given once weekly by subcutaneous injection; Semagultide (Ozempic®, Wegovy®): doses
of 0.25mg, 0.5mg, 1mg, 1.7mg, or 2.4mg can be given once weekly by subcutaneous
injection)
Male participants:
• If male and sexually active with female partner(s) of childbearing potential, participant
must agree, from Study Day 1 through 1 week after the last dose of study drug, to practice
the protocol specified contraception (see Appendix 4: Contraceptive Guidance and Collection
of Pregnancy Information).
Female participants:
• If a woman of childbearing potential (WOCBP), the participant must agree, from Study Day
1 through 1 week after the last dose of study drug, to practice the protocol specified
contraception (See Appendix 4: Contraceptive Guidance and Collection of Pregnancy
Information). All WOCBP must have negative result of a serum pregnancy test performed at
screening ( Females of non-childbearing potential include postmenopausal or permanently
sterile.)
Informed Consent
- Participant voluntarily agrees to participate in this study and signs an Institutional
Review Board (IRB)-approved informed consent prior to performing any of the Screening
Visit procedures.
- Participant must be able to understand the nature of the study and must have the
opportunity to have any questions answered.
Exclusion Criteria:
Participants are excluded from the study if any of the following criteria apply:
Medical Conditions
- Narcolepsy, restless leg syndrome requiring medication, rapid eye movement (REM) sleep
behavior disorder
- Current bothersome symptoms of insomnia (difficulty initiating or maintaining sleep,
as distinct from unrefreshing sleep or other symptoms attributable to OSA).
Participants being treated for insomnia can be enrolled only if the condition is
stable and generally controlled.
- Pierre Robin, Treacher Collins, or other craniofacial malformation syndrome, or grade
=3 tonsillar hypertrophy.
- Clinically significant or medically uncontrolled cardiovascular disease, e.g.,
ventricular arrhythmia requiring medical or device therapy, unstable atrial
fibrillation (including cardioversion, ablation, or change in antiarrhythmic regimen
within past 3 months [patients in whom anticoagulation is indicated must be on such
treatment for enrollment], or resting heart rate >100), untreated or unstable coronary
artery disease (including revascularization within 3 months), cardiac failure,
cerebrovascular event or transient ischemic attack or revascularization within 3
months.
- Neuromuscular disorder (e.g., motor neuron disease, muscular dystrophy, or myopathy,
myasthenic syndrome); epilepsy; Parkinson, Alzheimer, or other neurodegenerative
disease.
- Schizophrenia, schizoaffective disorder, generalized anxiety disorder or bipolar
disorder according to Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5)
or International Classification of Disease tenth edition criteria.
- Attempted suicide within 1 year prior to screening, or current suicidal ideation.
- Severe or frequent constipation considered currently bothersome by the patient, or
symptomatic gastric motility disorder.
- Current bothersome symptoms of bladder outlet obstruction including difficulty
initiating or maintaining urinary flow, straining, or sensation of incomplete bladder
emptying; participants being treated with alpha-1 adrenergic antagonist for benign
prostatic hypertrophy can be enrolled only if the condition is stable and generally
controlled.
- Active substance use disorder as defined in DSM-5, or other substance use that in the
investigator's opinion would present an unreasonable risk to the participant, or which
would interfere with their participation in the study or confound study
interpretation. Positive screen for drugs with abuse liability is an important but not
sole determinant of substance use disorder and study eligibility. Participants who use
marijuana daily should be excluded.
- A serious illness or infection in the past 30 days as determined by investigator.
- Clinically significant cognitive dysfunction as determined by investigator.
- Narrow angle glaucoma.
- Women who are pregnant or nursing. Prior/Concomitant Therapy
- Participants with prior use of mandibular advancement devices, nasal devices, or
sleeping position devices for the treatment of OSA may enroll as long as the devices
are not used during participation in the study.
- Participants with history of chronic oxygen therapy are excluded.
- Participants with implanted devices for the treatment of OSA are excluded (e.g.,
hypoglossal nerve stimulator, or investigational devices).
Prior/Concurrent Clinical Study Experience
• Use of another investigational agent within 30 days or 5 half-lives, whichever is longer,
prior to dosing.
Diagnostic Assessments
- Montgomery-Asberg Depression Rating Scale (MADRS-S) "zest for life" question response
of thinking of or planning suicide.
- Systolic blood pressure up to 140 mm Hg or diastolic blood pressure up to 90 mm Hg is
allowed in participants not currently treated with antihypertensives. If the
participant is under the care of a healthcare provider managing blood pressure and on
stable (at least 1 month) antihypertensive therapy, systolic blood pressure up to
145/90 is allowed at enrollment. If initial blood pressure (measured in triplicate,
use average of final two readings) is above this enrollment threshold, it may be
repeated up to a total of 3 times (each in triplicate) to confirm that the reading was
not due to measurement technique or transient factors, with selection of the lowest
repeated measure. The determination that blood pressure meets enrollment criteria
involves the clinical judgment of the investigator interpreting blood pressure
readings.
- Unexplained or new identification of hepatic transaminases (AST or ALT) >2X the upper
limit of normal (ULN) generally is exclusionary. However, elevation between 2-2.5 may
be allowed with prior consent of the sponsor if evidence suggests it is due to
nonalcoholic fatty liver disease (NAFLD) or other condition that would not be expected
to acutely worsen or require medical intervention during the course of the study.
- Total bilirubin >1.5X ULN (unless confirmed Gilbert syndrome).
- Estimated glomerular filtration rate < 50 ml/min.
- ECG abnormality indicative of clinically significant cardiac disease that may be
adversely affected by AD109 Other Exclusions
- Night- or shift-work sleep schedule which causes the major sleep period to be during
the day, including on a rotating basis.
- Frequent travel or jet lag is likely to interfere with study procedures or
evaluations.
- Employment as a commercial driver or other vehicle operator (includes independent
contractors and ride-share services).
- History of sleepiness-related motor vehicle accident (MVA).
- Unwilling to use specified contraception.
- Any condition that in the investigator's opinion would present an unreasonable risk to
the participant, including nature or severity of OSA symptoms, or which would
interfere with their participation in the study or confound study interpretation.
- Participant considered by the investigator, for any reason, an unsuitable candidate to
receive AD109 or unable or unlikely to understand or comply with the dosing schedule
or study evaluations.
