Multiple Sclerosis, Secondary Progressive

This study aims to understand the mechanisms of a novel intervention involving breathing short durations of low levels of oxygen for persons with multiple sclerosis (MS). This intervention with low levels of oxygen is called Acute Intermittent Hypoxia (AIH), the levels of oxygen experienced are similar to breathing the air on a tall mountain, for less than 1 minute at a time. Previous studies have shown that AIH is a safe and effective way to increase strength in persons with MS. Here the investigators aim to look at brain activation and ankle strength before and after AIH to gain a better understanding of how the AIH may improve strength in those persons with MS.

A Study of Anti-CD19 Chimeric Antigen Receptor T Cell Therapy in Subjects with Non-relapsing and Progressive Forms of Multiple Sclerosis

This study seeks to explore changes in the neural pathways and arm function following a breathing intervention in the multiple sclerosis (MS) population. The breathing intervention, known as Acute Intermittent Hypoxia (AIH), involves breathing brief bouts of low levels of oxygen. Research has found AIH to be a safe and effective intervention resulting in increased ankle strength in people with MS. Here, the study examines arm and hand function before and after AIH. In order to better understand the brain and spinal cord response to AIH, the investigators will measure muscle response, and signals sent from the brain to the arm muscles before and after AIH.

This prospective cohort study is part of the Clinnova programme and aims to (i) identify clinical imaging and omics characteristics associated with early Multiple Sclerosis (MS) and with transitioning phases to progressive MS, as well as (ii) to investigate digital biomarkers allowing the continuous clinical monitoring of those patients.

A study of alloHCT with Orca-Q for the treatment of primary progressive multiple sclerosis (MS).

The purpose of this study is to develop a measurement of walking quality, called Gait Deviation Index (GDI) for people with Multiple Sclerosis (MS).

This study is being conducted to investigate risk factors for disability progression in Multiple Sclerosis and related disorders (MSRD). The primary goal is to assess whether combining information from visual assessment, blood markers, as well as historical and ongoing longitudinal MRIs of the brain, orbit (the part of the skull where eyes are located), and/or spinal cord can predict changes in quantitative disability measures related to MSRD and neurological disease.

The purpose of the study is to evaluate the efficacy and safety of subcutaneously administered cladribine versus placebo to stop inflammation and treat disease progression of non-active secondary progressive multiple sclerosis. Multiple sclerosis is an inflammatory disease of the central nervous system. In most patients, it starts with a relapsing course (RMS) which is caused by acute inflammatory lesions in the brain and spinal cord. RMS transforms at later stages into progressive disease (secondary progressive MS). Currently approved disease-modifying treatments are effective in reducing clinical relapses and brain and spinal lesions visible in MR, but they perform poorly in preventing disease progression and overall disability accumulation. The growing evidence shows that disease progression partially depends on chronic inflammation present in the CNS. Drugs, which may cross the blood-brain barrier and reach inflammatory cells residing in the CNS might be effective in this stage of the disease. Cladribine is one of the DMT approved for RMS. It is a synthetic purine analog with selective lymphocyte toxicity, which enter the CNS and is found in cerebrospinal fluid. In patients treated with cladribine, the oligoclonal bands tend to disappear proving that neuroinflammation is diminished. The participants of this clinical trial with the later non-active stage of MS are enrolled to be treated with cladribine subcutaneously or a non-active comparator (placebo) for 6 months and followed for the next 2 years, with an MRI scan and clinical evaluation every 6 months. The main questions it aims to answer are if in the non-active stage of MS cladribine is potent to lessen brain volume loss and if it is potent to attenuate inflammation in the CNS.
