A Phase 3, Randomized, Double-Blind, Placebo-Controlled, 12-Month Study to Evaluate the Efficacy and Safety of MK-7264 in Adult Participants With Chronic Cough (PN030)

The primary objective of this study will be to evaluate the efficacy of gefapixant (MK-7264)
in reducing cough frequency as measured over a 24-hour period. It is hypothesized that at
least one dose of gefapixant is superior to placebo in reducing coughs per hour (over 24
hours) at Week 24.

This study will have a main 24-week treatment period and a 28-week extension period of
treatment.

Inclusion Criteria:

Screening/Visit 1 and after the onset of chronic cough) not demonstrating any
abnormality considered to be significantly contributing to the chronic cough or any
other clinically significant lung disease in the opinion of the principal investigator
or the sub-investigator

or unexplained chronic cough

- Is currently taking an angiotensin converting enzyme inhibitor (ACEI), or has used an
ACEI within 3 months of Screening

function

- Has a history of malignancy <=5 years

- Is a user of recreational or illicit drugs or has had a recent history of drug or
