Effect of Gefapixant (MK-7264/AF-219) on Cough Reflex Sensitivity in Healthy and Chronic Cough Participants (MK-7264-014)

Refractory Chronic Cough Clinical Trial

Official title:
A Study to Assess the Effect of MK-7264 (AF-219) on Cough Reflex Sensitivity in Both Healthy and Chronic Cough Subjects

Clinical Trial Summary

The primary objective of this study was to assess the effect of a single dose of gefapixant 100 mg on cough reflex sensitivity to various challenge agents (capsaicin, citric acid, adenosine triphosphate [ATP], and distilled water) in healthy and chronic cough participants.

Clinical Trial Description

The study had a Screening period to determine participant inclusion, two Baseline Visits, and two treatment periods with a minimum 48-hour washout between the treatment periods. At Baseline and during each treatment period, cough sensitivity was measured by standard clinical methodology incorporating four cough challenges. Daytime cough monitoring was performed at Baseline and during each of the two treatment periods (chronic cough participants only). ;
