Background and study aims
Amyotrophic Lateral Sclerosis (ALS; also known as motor neuron disease) is an incurable disease of the nervous system which causes the movement or 'motor' cells that control the muscles in the body to die. This leads to weakness, muscle loss and death within 5 years. A drug called Riluzole is the only drug currently available to slow down ALS progression, but this can only prolong survival by a few months at most and so better treatments are urgently needed. The aim of this study is to use magnetic resonance imaging (MRI), a type of scan that produces detailed images of the inside of the body, to better understand the way in which nerve cells die in ALS, particularly the role that inflammation may have in the damage to the brain.
Who can participate?
Patients aged 18 to 75 with ALS participating in the MIROCALS study
What does the study involve?
The study runs alongside another study called MIROCALS which tests whether a low dose of a chemical called interleukin-2, which is used by cells in the immune system to signal to each other, can safely improve the survival times of patients with ALS. All patients participating in MIROCALS take standard Riluzole treatment for 3 months, then are randomly allocated into one of two groups: one group receives additional low dose interleukin-2 (ld-IL-2); the other receives additional placebo (dummy drug) treatment. A range of substances, called biomarkers, which relate to nerve cell damage and immune system function, are measured from patients' spinal fluid and blood, and the severity of their disease is assessed. This study recruits 50 patients from MIROCALS for MRI scanning at the start of the study (whilst on Riluzole only) and again 4-6 months after allocation to either additional treatment. The healthy volunteers only require one scan whereas patients with ALS have two scans roughly 5-7 months apart. The types of scan include Neurite Orientation Dispersion and Density Imaging (NODDI), which provides data on nerve cell density and the extent of their branching connections with other cells; quantitative magnetisation transfer (qMT) imaging, which measures primarily nerve cell insulation (myelin) content and composition; and resting state functional MRI (rsfMRI) to study the degree to which various brain regions communicate with each other at rest. The scans take about 50 minutes to complete in total. The brain scans are then compared with similar brain scans from a group of healthy volunteers (recruited into a separate study called MultiNICS), and between the two groups of patients treated with either Riluzole and Placebo or Riluzole and ld-IL-2. The degree of change on the MRI scans is also compared to the levels of the biomarkers and measures of disease severity.
What are the possible benefits and risks of participating?
It is hoped that the study will yield vital clues as to the processes by which the brain becomes damaged in ALS and not only assist in the development of further treatments but assist with the design of future studies in this field. Some of the MRI techniques used are relatively new but are as safe as having a 'normal' MRI brain scan and none require any invasive tests such as injections.

| Scientific title | Analysing Neuroinflammation and Neurodegeneration in Amyotrophic Lateral Sclerosis: Quantitative Imaging in a Clinical Trial |
| Study acronym | ANNALS-QuICT |
| Study objectives | Current study hypothesis as of 24/03/2017: 1. Baseline parameters measured by the detailed magnetic resonance imaging (MRI) will be significantly different in patients with ALS compared to a group of healthy control subjects (recruited into a separate study called MultiNICS) 2. Baseline parameters in patients with ALS will be able to predict rate of progression and relate significantly to the ‘intensity’ of nerve cell damage & inflammation reflected by biomarker levels of, for instance, neurofilament proteins and inflammatory cytokines, respectively, as measured by the MIROCALS study 3. MRI parameters will demonstrate progression over time between the baseline and follow-up scan in patients with ALS 4. If the MIROCALS trial is positive, there will be greater progressive change in MRI parameters between baseline and follow-up in patients treated with Riluzole + placebo compared to Riluzole + ld-IL-2 Previous study hypothesis: The main hypotheses are: 1. That parameters of neural disruption measured by the detailed magnetic resonance imaging (MRI) brain images, including Neurite Orientation Dispersion and Density Imaging (NODDI), quantitative magnetization transfer imaging (qMTi) and resting state fMRI (rsfMRI) sequences, will be significantly increased in patients compared to controls at baseline. 2. That the degree of disruption on MRI for each patient will be able to predict their rate of disease progression and be significantly associated with ‘intensity’ of neurodegeneration and neuroinflammation reflected by biomarker levels of, for instance, neurofilament proteins and inflammatory cytokines, respectively, as measured in the MIROCALS study. 3. That changes in MRI indices between baseline and follow-up scans in patients will be reflected by changes in clinical progression, as well as their ‘intensity’ of neurodegeneration and neuroinflammatory measured by the MIROCALS biomarkers. |

| Health condition(s) or problem(s) studied | Motor neuron disease, also referred to as amyotrophic lateral sclerosis |
| Intervention | Current interventions as of 24/03/2017: The “Analysing Neuroinflammation and Neurodegeneration in Amyotrophic Lateral Sclerosis (ALS): Quantitative Imaging in a Clinical Trial” (ANNALS-QuICT) study will perform detailed quantitative magnetic resonance brain imaging (MRI) on patients with ALS. ANNALS-QuICT is an ancillary study to a double-blind randomised placebo-controlled trial called MIROCALS and only UK patients enrolled into MIROCALS are eligible. 50 patients from MIROCALS will undergo baseline MRI scans and again 4-6 months after they have been randomised to treatment. The MRI techniques to be used include Neurite Orientation Dispersion and Density Imaging (NODDI) which provides data on nerve cell architecture and density; quantitative magnetisation transfer (qMT) imaging which provides measures primarily about nerve cell insulation (myelin) content and composition; and resting state functional MRI (rsfMRI) to study the degreeto which brain regions communicate at rest. The principal brain regions of interest for analysis will be the brain surface controlling movement (primary motor cortices), the projection of these fibres into the spinal cord (corticospinal tracts), a major connection between the two brain hemispheres (the corpus callosum) and a known resting state (sensorimotor) network, although whole brain analyses will be possible with the extensive imaging data acquired. There is no active intervention or additional follow-up as the parent trial MIROCALS will do this over 18 months and share its data with ANNALS-QuICT. Previous interventions: This is an ancillary study to a double-blind randomised placebo-controlled trial called MIROCALS, which will perform detailed quantitative MR brain imaging on a proportion of patients enrolled into MIROCALS along with a healthy age-matched control group This project will use detailed quantitative magnetic resonance imaging (MRI) to understand the mechanisms of the neurodegeneration in ALS, particularly the role of neuroinflammation in this process. The project will run in the context of a unique double-blind, randomised controlled trial called MIROCALS (Modifying Immune Responses and Outcomes in ALS) using low dose interleukin-2 (ld IL-2) to increase white blood cells known as regulatory T-cells (Tregs). Treg numbers correlate positively with survival in ALS, perhaps by altering the balance of harmful inflammation occurring in the brain and spinal cord. Patients with ALS recruited to MIROCALS will all take Riluzole for 3 months, then be randomised to receive additional ld IL-2 or placebo treatment for a further 18 months. A range of spinal fluid and blood molecular ‘biomarkers’ will be measured serially to correlate with clinical outcomes such as survival and functional status. 50 patients from MIROCALS will undergo MRI scans at baseline (on Riluzole only) and again 4-6 months after randomisation to treatment, along with 25 healthy age-matched controls for comparison. The novel MRI techniques to be used include Neurite Orientation Dispersion and Density Imaging (NODDI) which provide data on nerve cell architecture and density; quantitative magnetisation transfer (qMT) imaging which provides measures primarily on nerve cell insulation (myelin) content and composition; and resting state functional MRI (rsfMRI) to study the degree to which brain regions communicate at rest. The principal brain regions of interest for analysis will be the brain surface controlling movement (primary motor cortices), the projection of these fibres into the spinal cord (corticospinal tracts) and a known resting state (sensorimotor) network, although whole brain analyses will be possible with the extensive imaging data acquired. There is no active intervention or additional follow-up as the parent trial MIROCALS will do this over 18 months and share its data. |
