About this study

The WISPer study is looking at a new drug called MTX-463.

WISP1 is a protein that plays an important role in the development and progression of fibrosis (scarring). Because of this, it is being studied as a possible target for new treatments.

MTX-463 is a new type of drug designed to block the harmful effects of WISP1. This may act to help treat different types of fibrosis, such as in the lungs and liver. Researchers will look at the impact of this for people with IPF. This study aims to look at the effect of the drug and the impact it has on the body to see if it is safe and effective.

What is involved?

You will be randomly assigned to one of two groups. One group will receive an intravenous infusion of the study drug, MTX-463, and the other group will receive a matching placebo, which does not contain any active medication.

You will receive infusions every four weeks for 5 months, after this you will have monitoring appointments for 8 weeks. At each hospital visit you will also have various medical assessments and tests to see how your body responds to the drug. This will include blood tests every 4 weeks, lung function tests at each hospital visit and questionnaires at the start and end of the study.

You are still able to continue taking antifibrotic drugs (pifenidone or nintedanib) whilst taking part in this study.

Summary of involvement

Taking part in the study for up to 32 weeks

Taking either the study drug or a placebo via an infusion every four weeks

Medical assessments including lung function tests

Questionnaires

Can I take part?

You may be able to take part if you are over the age of 40 years and have a diagnosis of IPF.

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 the main criteria 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 without this effecting your usual care or treatment.

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 out more about other research opportunities visit our research finder main page.

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

You are age 40 years or older

You have a diagnosis of Idiopathic Pulmonary Fibrosis (IPF)

If you are taking pirfenidone or nintedanib, the dose of the medication must be stable for the last 90 days

If you are not taking nintedanib or pirfenidone you must have stopped this at least 30 days before the study, or have never taken it

There are also specific lung function requirements, which will be assessed by the research team

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

You have had an acute exacerbation of IPF within the last 6 months

You require continuous supplemental oxygen therapy

What difference could taking part make?

Taking part in this study may not bring direct benefit to you, but the information researchers learn from the study will help to understand the impact of the drug for people with IPF.
