About this study
The CORAL study is understanding whether a drug called nalbuphine extended release (ER) could treat chronic cough in people with Idiopathic Pulmonary Fibrosis (IPF). The extended release means that the drug is slowly and consistently released over a period of time.
Cough is one of the most common symptoms for people with IPF and there are currently no approved treatments to help reduce it. Doctors sometimes prescribe medicines that may slow down the scarring process or medications to reduce the inflammation in the lungs. However, patients may not experience relief from coughing.
This drug has been tested in a small group of people.
The aim of this clinical trial is to confirm if similar results are found in a larger number of people with IPF. This will help researchers to understand how the drug works and whether different doses of the study drug, nalbuphine, may help to reduce cough for people with IPF.
What is involved?
You will be assigned to one of four groups in this trial:
- placebo tablets twice a day
- oral nalbuphine ER 27mg twice a day
- oral nalbuphine ER 54mg twice a day
- oral nalbuphine ER 108mg twice a day
Three out of every four people will receive the study drug, nalbuphine as a tablet. One out of every four people will receive placebo. A placebo is a tablet that looks the same as the drug, but does not contain any of the active ingredients. You will not know which tablet you have been given.
If you would like to join the study, you will be assessed to confirm if you are eligible to take part. If you are able to take part, you will have 6 in-person study visits and 2 check-in phone calls. During the on-site visits, the study team will carry out various medical assessments and occasionally place a wearable cough monitor on you to use for a 24-hour period. Additionally, you will be asked to complete daily surveys on a digital tablet throughout the study.
Travel reimbursement will be made available to you.
Summary of involvement
6 weeks of taking nalbuphine ER tablets twice per day.
Medical assessments.
Wearing a 24-hour cough monitor four times throughout the study.
Completing surveys using an electronic diary.
Can I take part?
Approximately 160 people from around the world are expected to take part in this trial. To be able to take part, you must meet certain criteria. Please note that the list below is a summary, and does not include all the reasons why you may or may not be able to take part. The study physician will inform you whether you are eligible to participate in this study.
In research studies, there are lots of different reasons why you may or may not be able to take part. These are known as inclusion and exclusion criteria (see list below). Only the research team will be able to fully determine whether you are able to take part in the study. You can withdraw at any point.
If you are not able to take part in this research study, there may be other opportunities for you to take part in different studies.

What difference could taking part make?
As with all trials with new potential treatments, there is no guarantee that it will work. Currently, nothing is approved to treat chronic cough in IPF and continued research of nalbuphine ER may help you and other people with IPF in the future.
