MIROCALS (Modifying Immune Response and Outcomes in Amyotrophic Lateral Sclerosis) is a clinical trial currently taking place in the UK and France. It is testing a new potential therapy for ALS, the most common form of MND.

Now recruiting MND patients in Glasgow, who meet the criteria, the study will focus on types of immune cells in the blood, which are capable of influencing the speed at which ALS progresses. This is because these immune cells are believed to play a part in protecting the motor neurones.

What is the MIROCALS Clinical Trial?

MIROCALS (Modifying Immune Response and OutComes in ALS) is recruiting for participants in Glasgow, who meet a list of certain criteria, however patients from across Scotland can find out more about participating using the contact details below. 

The trial will focus on those affected by Amyotrophic Lateral Sclerosis (ALS) - the most common form of Motor Neurone Disease.

The study will focus on some types of immune cells in the blood which are capable of influencing the speed at which ALS progresses. This is because these immune cells, called Regulatory T Cells, are believed to play a part in protecting the motor neurones.

A substance which is naturally produced in the body, called Interleukin-2, can increase the production of these special immune cells in the blood.

As a result, the trial will test the safety and effectiveness of introducing low doses of Interleukin-2 in people with ALS. The purpose of this is to stimulate the production of the immune cells and to explore whether increased levels of these can slow down the progression of the disease.

Interleukin-2 is already used, at higher levels, to treat some forms of cancer. However, due to some of its undesirable side effects on the immune system, only small doses are recommended for non-cancerous diseases.

Who can apply for the MIROCALS trial?

There are entry requirements for the trial which include the fact that patients who wish to participate cannot be taking or ever have taken Riluzole. Please read this information sheet for more details on the trial criteria.

The trial is currently recruiting in Glasgow, however patients from across Scotland can register their interest. See contact details below.

Patients who are recruited to the trial will need to travel to Glasgow to participate.

How will we know if it works?

To test the effectiveness of the treatment, researchers will measure its success based on rate of progression, changes in day-to-day activities and quality of life. In addition, any side effects that people may experience when taking this drug will be closely monitored.

As a secondary goal, the researchers will search for biomarkers, unique biological signatures, in the blood and cerebrospinal fluid (CSF). Finding biomarkers for ALS would allow researchers to determine whether a drug is working. The discovery of these biomarkers would also mean that clinicians are able to diagnose ALS faster and to better monitor the progression of the disease.

What are clinical trials?

A clinical trial is a scientifically controlled study exploring both the effectiveness and safety of a particular therapeutic treatment, such as a drug.

In most clinical trials, including MIROCALS, the impact of a treatment is determined by comparing groups of patients who do receive treatment (treatment or experimental group) and do not receive the treatment (control or placebo group).

The approach means that participating in a clinical trial does not guarantee that an experimental treatment will be received.

Any therapy approaching the first small-scale trials in humans will already have undergone a lengthy period of development and testing in the laboratory.

The involvement of human patients only occurs at the last stage of testing before a drug is licensed for general use.

Participating in a clinical trial – what you need to know

  • Clinical trials are not treatments – they are experiments which aim to develop treatments
  • Neither the person with MND, nor the doctors, will be aware of who is receiving the treatment and who is receiving the placebo
  • Criteria (age, type and stage of MND, and previous/current treatments) may determine eligibility
  • It is important to consider the potential benefits and risks of taking part in a clinical trial
  • The very presence of clinical trials into MND is a positive step in the search for a cure
