Clinical Trial Summary

The goal of this observational study is to evaluate the slowing/reduction of cognitive dysfunction progression and to evaluate grey matter (GM) and thalamus structural changes in Relapsing-Remitting Multiple Sclerosis (RRMS) patients after 12 months of treatment with Dimethyl Fumarate (DMF). The main questions it aims to answer are: - Can DMF slow or reduce the progression of cognitive dysfunction in RRMS patients? - Can DMF slow the reduction of brain volume in RRMS patients? At baseline visit, RRMS patients undergo extensive neurological examination in which their disability is evaluated by using Expanded Disability Status Scale (EDSS). The efficacy assessments of this study are: 1. The Brief Repeatable Neuropsychological Battery (BRB); 2. Executive functions: Delis-Kaplan Function System (DKEFS) scale - Sorting Test. All RRMS patients undergo MRI: conventional MRI measures (T2-, T1-enhancing and T1-hypointense lesions), global brain atrophy, regional brain atrophy and Diffusion Tensor Imaging (DTI) (GM and thalamus) examinations. Six and 12 months after the baseline visit, the RRMS patients in treatment with DMF undergo the BRB, DKEFS and MRI/DTI study and neurological evaluation (EDSS).


Description:

Dimethyl fumarate (DMF) is an oral disease-modifying therapy (DMT) approved for management of Relapsing-Remitting Multiple Sclerosis (RRMS) patients. Clinical trials have shown that DMF has a significant beneficial impact on relapse rate, disability accrual and the number of new lesions along with their volumes. In addition, a neuroprotective role of DMF has been suggested to occur on both the gray matter (GM) and thalamus. However, there are no correlation data in the literature between the effects of DMF on cognitive performance and those on the GM, with a focus on thalamic pathology in MS patients. The primary objectives of this study are: i) to evaluate the slowing/reduction of cognitive dysfunction progression in RRMS patients after 12 months of treatment with DMF; ii) to evaluate the effects of DMF on Magnetic Resonance Imaging (MRI) parameters in GM and thalamus. The secondary objective is to evaluate how the effects on cognitive dysfunction progression are associated to the effect of slowing the brain volume reduction at MRI (antiatrophic effect) and to change of Diffusion Tensor Imaging (DTI) parameters that DMT might have in RRMS patients, in the GM and thalamus. The tertiary objective is to assess whether differences exist between patients with RRMS de novo to DMF treatment and patients switching from first-line DMT to DMF. After signing informed consent, demographics, medical history and current therapies are collected for each RRMS patient enrolled. RRMS patients undergo extensive neurological examination in which their disability is evaluated by using EDSS. The efficacy assessments of this study are: 1. The Brief Repeatable Neuropsychological Battery (BRB) 2. Executive functions: Delis-Kaplan Function System (DKEFS) scale - Sorting Test. All MS patients undergo MRI: conventional MRI measures (T2-, T1-enhancing and T1-hypointense lesions), global brain atrophy, regional brain atrophy and DTI (GM and thalamus) examinations. Six and 12 months after the baseline visit, the RRMS patients in treatment with DMF undergo the BRB, DKEFS and MRI/DTI study and neurological evaluation (EDSS).

Type Measure Description Time frame Safety issue
Other Difference between the two cohorts Difference between the two cohorts in terms of mean changes in total score of BRB and DKEFS scale and in terms of mean changes in brain volume and DTI parameters (in GM and thalamus). Baseline and 6 and 12 months after.
Primary Change in subjects' cognitive performance Change from baseline in Selective Reminding Test - Long-Term Storage (SRT-LTS) Raw Score of Brief Repeatable Battery (BRB) at 6 months. This is one of the five tests of BRB for episodic memory (verbal learning and delayed recall). A word recalled on two consecutive trials is considered to have entered long-term storage (LTS) on the first of these trials and scored as LTS on all following trials. The total score ranged from 0 to 72. Higher values represent a better outcome. Month 0 Baseline to Month 6 Follow-up
Primary Change in subjects' cognitive performance Change from baseline in Selective Reminding Test - Consistent Long Term Retrieval (SRT-CLTR) Raw Score of Brief Repeatable Battery (BRB) at 6 months. This is one of the five tests of BRB for episodic memory (verbal learning and delayed recall). A word recalled on two consecutive trials is considered to have entered long-term storage (LTS) on the first of these trials and scored as LTS on all following trials. The total of the words in LTS of all six trials is then summed. If a word in LTS is consistently recalled on all subsequent trials, it is then scored as Consistent Long Term Retrieval (CLTR). The total of the words in CLTR of all six trials is summed. The total score ranged from 0 to 72. Higher values represent a better outcome. Month 0 Baseline to Month 6 Follow-up
Primary Change in subjects' cognitive performance Change from baseline in Spatial Recall Test (SPART) Raw Score of Brief Repeatable Battery (BRB) at 6 months.

Primary Change in subjects' cognitive performance Change from baseline in Word List Generation (WLG) of Brief Repeatable Battery (BRB) at 6 months. Word List Generation (COWAT/WLG): The COWAT assesses verbal fluency on semantic stimulus by asking the patient to produce as many words as possible belonging to a semantic category. No maximum range is available. Higher values represent a better outcome. The score is the number of correct words. The more words the patient pronounces, the better it is. We can imagine that the minimum value might be zero words, but it is not a score scale. Month 0 Baseline to Month 6 Follow-up
