Testing nerve blockers and cough control for chronic cough
Treatments studied
Part of Lungs & breathing clinical trials.
This study tests two treatments—nerve blockers and a cough control therapy—for people with chronic cough that hasn't improved with standard treatments or has no clear cause. The goal is to find better ways to reduce coughing and improve quality of life.
Summary written for real people, not researchers, by Clin2.

Other trials that look related to this one.
This Phase 2 study tests whether two doses of duloxetine and amitriptyline can reduce symptoms in people with chronic cough that hasn’t responded to usual care. You may join to see if these medicines lessen cough severity over an 8-week blinded treatment period.
This trial tests whether an extended-release medication called nalbuphine can reduce coughing in people with chronic cough that hasn't improved with other treatments. You may be eligible if you've had a persistent cough for at least a year and have already tried treatments for conditions that could cause it.
This study tests a behavior-based therapy to help you gain control over a persistent cough that hasn't responded to other treatments. You will learn techniques to reduce coughing during a 4-week program.
This trial studies an office-based injection to calm a specific nerve in the neck to treat chronic cough that seems to come from nerve irritation (“neurogenic/sensory neuropathic” cough). It may help people whose cough has lasted at least 8 weeks and continues despite standard treatments for common cough causes.
This study tests a behavioral therapy delivered through group video calls to help people with a chronic dry cough that has no clear cause. It may offer a non-drug way to reduce coughing.
This 24-week study tests whether a new medicine called BLU-5937 can help adults whose chronic cough hasn't improved with standard treatments. Chronic cough that lasts a year or longer can seriously affect quality of life, and this trial explores whether this drug might provide relief.
