Filter by:Study design: Single arm open-label clinical trial in ataxia-telangiectasia to test the effects of nicotinamide riboside on ataxia scales, immune function, and neurofilament light chain. Study population: 6-10 patients with Ataxia-Telangiectasia. Dose: Nicotinamide riboside 25 mg/kg/day in 3 equal divided doses. Primary endpoint: Scales for assessment and rating of ataxia (SARA), and International Cooperative Ataxia Rating Scale (ICARS). Improvement of at least ½ standard deviation in key clinical scales which includes either; a) significant improvement in total combined scores from the SARA and ICARS scales, and /or b) significant improvements any aspects of the SARA and ICARS scales individually, especially pertaining to; Postural and gait improvements, Improved syllable speed and articulation, Improved fine motor skills. Secondary endpoints: Serum analysis of neurofilament light chain (Nfl), Type 1 Interferon (INFs) epigenetic signature
This is an international, multi-center, randomized, prospective, double-blind, placebo-controlled, Phase 3 study, designed to assess the effect of EryDex (dexamethasone sodium phosphate [DSP] in autologous erythrocytes), administered by intravenous (IV) infusion once every 28 days, on neurological symptoms of patients with Ataxia Telangectasia (A-T).
Ataxia Telangiectasia (A-T) is an autosomal recessively inherited neurodegenerative disorder that also has dramatic effects on the immune and endocrine systems. The disorder results from mutations in the A-T mutated gene (ATM) leading to a loss in the production of the ATM protein. The active compound in MBM-01 (4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl) may substitute for the loss of ATM by protecting cells from DNA damage, preventing and reducing oxidative damage, triggering an increase in cellular survival proteins, and preserving the brain and peripheral immune system.
Ataxia-telangiectasia (AT) is a rare genetic disorder characterized by gait disorders, neuromotor dysfunction, eye abnormalities and immune deficiency. AT patients are vulnerable to cancer and infection and usually die during their 2nd or 3rd decade due to these complications. The main cause of death is respiratory infections because these patients are known to have severe type of immunodeficiency. Consequently, pneumonia is the most common infection seen in AT patients, and is usually caused by S. pneumoniae. Therefore, a routine schedule of pneumococcal vaccine is highly recommended in AT cases where immunoglobulin replacement therapy was not already initiated. Until recently, AT patients were immunized with the pneumococcal polysaccharide vaccine (PPV23, Pneumovax® Aventis Pasteur MSD). However, data have shown that they do not respond well to these vaccines. Recently, the Israeli Ministry of Health has approved the pneumococcal 7-valent conjugate vaccine (PCV7, Prevenar®, Wyeth Lederle) for AT patients of all ages. This conjugate vaccine is known to stimulate the immune system through a different mechanism and the response is expected to be higher. The approved Israeli schedule for immunization of AT patients includes children older than 2 years that are entitled to receive 2 doses of PCV7 (8 weeks apart) boosted by PPV23, eight weeks after the second dose of PCV7. Assessment of the antibody response of such pneumococcal vaccination protocol in AT patients has never been performed. The "Safra" Children's Hospital is the national multi-disciplinary center caring for AT patients. Approximately 50 patients from all over the country (including Jewish, Druze, Bedouin and other Muslim patients - 3 of whom are Palestinians) are followed in the clinic on a monthly basis. Approximately 20 AT patients are not receiving IVIG replacement therapy, therefore are entitled to receive pneumococcal vaccination as stated above (mean age 10.6, 3 -23 years, 3 less than 5 years) The aim of this study is to evaluate the responsiveness, determined by specific antibody production, of AT patients receiving this new vaccine protocol.
