Official title: Mechanisms of Change in Behavioral Cough Suppression Treatment for Refractory Chronic Cough

Funded at University of Montana · NIH-11418499 · Data updated 2026-11-12

A multi-site study will test how a behavioral therapy for stopping cough works alone and with capsaicin to help people with stubborn chronic cough.

Who could benefit from this research

Could help

Adults with refractory chronic cough who can undergo behavioral therapy and capsaicin exposure.

Less likely to help

Some participants may not experience noticeable improvement or may experience discomfort from capsaicin exposure.

What this research studies

This trial explores how teaching patients to suppress cough and pairing it with capsaicin exposure may reduce coughing in people with refractory chronic cough. Participants will be randomly assigned to three groups and will complete 12 treatment sessions over the study period. Researchers will look at changes in cough frequency and the sensitivity of cough responses to capsaicin, aiming to understand why the therapy helps some patients more than others. The study builds on earlier pilot work and uses a rigorous, multi-site design to uncover the mechanisms behind therapeutic responses. Overall, the goal is to improve practical treatment options for RCC and reduce its burden on patients and healthcare systems.

Why it matters

Potential benefit: If successful, patients may experience fewer coughing episodes and better control over their symptoms, improving quality of life.

How similar studies have gone: Preliminary pilot data suggested promise for the combined approach, with prior small studies showing potential benefits.
