Study on the Safety of Drug BAY2586116 and How it Works in Patients With Obstructive Sleep Apnea (a Sleep Disorder Caused by the Narrowing and Collapse of the Airway During Sleep) Including the Blood Level of the Drug and Effect of Its Doses and Routes of Administration — KOALA  

Sleep Apnea, Obstructive Clinical Trial

Official title: Proof-of-mechanism Single-center, Randomized, Double-blind, Placebo-controlled 2-way Crossover Study to Investigate Pharmacodynamics, Safety, Tolerability and Exposure of BAY 2586116 (Part A) and an Open-label Comparison of Different Application Modes for Single Nasal/Pharyngeal Dose Administrations (Part B and Part C) in 12 Participants With Obstructive Sleep Apnea

Status Completed

Clinical Trial Summary

The researchers in this study want to learn how drug BAY2586116 works in patients with obstructive sleep apnea (OSA). OSA is a sleep disorder marked by breathing pauses during sleep due to repetitive obstructions of the upper airway. BAY2586116 is a new drug under development for the treatment of OSA. It blocks protein channels expressed on the surface of the upper airways in small mechanoreceptors (a type of molecule that sense and pass stimulus outside a cell on to the inside of the cell through mechanical gate on the surface of the cell). Thus, the negative pressure reflex alerting the brain of inspiration is triggered more easily leading to a stronger activation of throat muscles. This prevents narrowing or collapse of the upper airways during sleep which is one of the pathological key factors in OSA.

Researchers will study the effects of different routes of administration (drops into the nose, spray into the nose or throat or spray into the throat by endoscopy). Endoscopy allows the doctor to look at areas in the throat that cannot be seen with a mirror: a thin tube-like instrument is inserted through the nose to check and give the medication. Different doses of the test drug will be given.

They also want to find out if participants experience any medical problems during the study.

Patients participating in this study will undergo three study parts. After completing Part A and Part B, participants will be asked to join Part C. In Part A, participants will receive both the test drug and placebo (a placebo looks like the test drug but does not have any medicine in it); in Part B, participants will receive the test drug twice via different routes of administration (drops in nose and spray in nose or throat) and in Part C, the participants would receive the test drug once via spray in throat by endoscopy. The sleep of the participants will be monitored by medical equipment. Participants will be asked to visit the clinic 7 times in 14 weeks in total.
