Study summary
What the protocol is testing.
This study is being done to look at the efficacy and safety of NNC0487-0111 in participants with excess body weight and obstructive sleep apnoea not treated with positive airway pressure lose weight and improve sleep apnoea. There are 2 study treatments in this study taken as injections under the skin once a week. Participants will either get NNC0487-0111, (the treatment being tested) or Placebo (a treatment that has no active medicine in it) and which treatment participants get is decided by chance.
Interventions
Treatment arms and agents.
DRUG
Placebo (matched to NNC0487-0111)
Placebo matched to NNC0487-0111 will be administered subcutaneously using PDS290 pre-filled pen-injectors to one of the body parts: thigh, abdomen or upper arm.

Outcomes
What the study measures.
Primary outcomes
Relative change in body weight
Time frame · From baseline (week 0) to (week 80)
Measured as percentage (%) change in body weight.
Change in apnoea-hypopnoea index (AHI)
Time frame · From baseline (week 0) to (week 80)
Measured as events/hour.
Secondary outcomes
Relative change in AHI
Time frame · From baseline (week 0) to (week 80)
Measured as percentage change in AHI.
Achievement of 50% reduction in AHI (Yes/No)
Time frame · From baseline (week 0) to (week 80)
Measured as number of participant.
Achievement of: AHI less than (<) 5
Time frame · From baseline (week 0) to (week 80)
Measured as number of participants.
Achievement of: AHI 5-14 with Epworth Sleepiness Scale (ESS) ≤ 10 (Yes/No)
Time frame · From baseline (week 0) to (week 80)
Measures as number of participants
Change in sleep apnoea specific hypoxic burden (SASHB)
Time frame · From baseline (week 0) to (week 80)
Measured as percentage minutes per hour (%min/h).
Change in ESS score
Time frame · From baseline (week 0) to (week 80)
Measured as score on a scale. ESS measures the level of daytime sleepiness or average sleep propensity. The measure consists of 8 items yielding one total score. Total score ranges from 0-24. Higher scores indicate higher sleepiness or average sleep propensity in daily life.
Change in Patient-Reported Outcomes Measurement Information System (PROMIS) Short Form v1.0 Sleep-Related Impairment 8a score
Time frame · From baseline (week 0) to (week 80)
Measured as score on a scale. PROMIS-SRI measures perceptions of alertness, sleepiness, and tiredness during usual waking hours, and the perceived functional impairments during wakefulness associated with sleep problems or impaired alertness. The measure consists of 8 items each rated on a 5-point scale ranging from "not at all" to "very much". Individual item scores will be combined and converted to a T-score using a response pattern scoring approach. The T-score standardises the raw score to a distribution with a mean of 50 and standard deviation of 10. Total score (T-score range): Sleep-related impairment (ranging approximately from 30-80.1). Higher scores indicate more sleep-related impairment.
Change in PROMIS Short Form v1.0 Sleep Disturbance 8b score
Time frame · From baseline (week 0) to (week 80)
Measured as score on a scale. PROMIS-SD measures perceptions of sleep quality, sleep depth, and restoration associated with sleep. The measure consists of 8 items each rated on a 5-point scale ranging from "not at all" to "very much," "never" to "always," or "very poor" to "very good". Individual item scores will be combined and converted to a T-score using a response pattern scoring approach. The T-score standardises the raw score to a distribution with a mean of 50 and standard deviation of 10. Total score (T-score range): Sleep disturbance (ranging approximately from 30-80.1). Higher scores indicate more sleep disturbance.
Change in body weight
Time frame · From baseline (week 0) to (week 80)
Measured as kilogram (Kg).
Change in body mass index (BMI)
Time frame · From baseline (week 0) to (week 80)
Measured as kilograms per meter square (kg/m\^2).
