About this study

The study is randomised control trial which looks at the effects of a new drug called Zelasudil (RXC007), for people diagnosed with IPF.

Zelasudil targets a point in the lung cells that are involved in cell signalling, which plays a key role in both inflammation and changes in the lung structure that drives disease progression in many fibrotic conditions.

The aim of the study is to gain greater understanding about how the body responds to the drug and if it is suitable for people with IPF.


What is involved?

You will be involved in the study for up to 12 weeks. You will be randomly assigned into different groups. One group will be given the drug, Zelasudil, whereas the other group will be given a placebo. A placebo does not contain any active ingredients of the study drug and is a lookalike medication. If you are in the group that is given the drug, it will be given at different doses, depending on the timepoint at which you take part in the study.

When you take part in the study, the researchers will record your vital sign measurements at different timepoint, such as blood pressure, pulse rate, respiration rate and temperature; ECG recordings; and blood tests to gain understanding of how your body responds to the drug. Lung function tests will also be carried out.

After the study has finished, you will also be given an opportunity to take the drug for an additional 12 weeks, if you would like to. This option is available to both groups.

Can I take part?

You may be able to take part if you are aged between 40 and 80 years, and have a diagnosis of IPF within the last 5 years

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 clinical trial 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.

To find our more about other research opportunities visit our research finder main page.

You may be able to join this study if all of these apply:

Aged between 40 and 80 years

Any gender

Diagnosis of IPF within the last 5 years

If taking nintedanib or pirfenidone, the participant must have been receiving treatment for at least 3 months, and on a stable dose for at least 4 weeks

There is a set lung function criteria to be able to take part in the study, which will be assessed by the research team

You will not be able to join the study of any of the following applies:

Currently or planning to receive treatment for IPF that is not approved for the disease

Lower respiratory tract infection requiring antibiotics within the last 4 weeks

Oxygen therapy for more than 15 hours per day

Acute exacerbation within the last 6 months

Diagnosis of connective tissue disease or interstitial pneumonia with autoimmune features

Other disease where life expectancy is less than 12 weeks

What difference could taking part make?

People affected by idiopathic pulmonary fibrosis IPF currently have limited treatment options to slow the progression of disease. New research studies, such as this one, are needed to gain valuable knowledge about potentially better treatment options.

Taking part in this study will help researchers to understand if Zelasudil could be an effective treatment for patients with IPF. The study will help to gain greater understanding of the medication, if it is safe and well tolerated, along with how the body responds to the drug.

Participation in research has the potential to make a difference for people who have PF now and for future generations.
