Description of intervention(s) / exposure
Treatment: Drugs - BAY2586116
Treatment: Drugs - Placebo

Placebo comparator: Placebo - Placebo (saline) nasal spray, taken before bedtime. Dosage is taken on one instance for one night only.

Eligibility
Key inclusion criteria
* Male or female participants aged 18 years or older at screening
* Must have completed Part A of the KOALA study (NCT04236440)

* Must be willing to refrain from drinking alcohol on the study days.
* Must be willing to limit consumption of tobacco to four cigarettes or one cigar a day and not smoke while at the sleep laboratory. This might be up to 12 hours.
