NCT ID: NCT04925349 Recruiting - Clinical trials for Adrenoleukodystrophy

Modeling Macrophages Activation Pattern in X-linked Adrenoleukodystrophy, Metachromatic Leukodystrophy and Adult Onset Leukoencephalopathy With Axonal Spheroids and Pigmented Glia

MATRIX
Start date: August 30, 2021
Phase:
Study type: Observational

This study is a national, non-randomized, open-label, multi-site with minimal risk study in adult with adrenomyeloneuropathy (AMN), childhood and adult subjects with cerebral ALD (cALD), juvenile/adult metachromatic leukodystrophy (MLD) and adults with leukoencephalopathy and axonal spheroids and pigmented glia (ALSP). 49 subjects will be enrolled with one blood sample collection during one of their medical follow-up visit. This trial will evaluate the role of innate immunity to influence disease progression in X-ALD, MLD and ALSP, and if the mutations related to these leukodystrophies result in a specific immune response leading to the pathogenesis.

NCT ID: NCT04303416 Completed - Clinical trials for Adrenoleukodystrophy

Plasma Exchange With Albumin in AMN Patients

Start date: March 9, 2020
Phase: Phase 2/Phase 3
Study type: Interventional

Adrenoleukodystrophy (X-ALD) is the most common genetic disorder of the brain white matter with an incidence of 1:14,700 births. It is caused by mutations in the ABCD1 gene, which encodes a transporter of very long-chain fatty acids (VCLFA) into the peroxisome for degradation. As a consequence VLCFA accumulate in tissues and plasma being the pathognomonic biomarker for diagnosis. The excess of VLCFA produces mitochondrial ROS and oxidative damage, a major factor driving X-ALD pathogenesis. Other key dysregulated pathways are energy production, mitochondrial biogenesis and respiration, proteostasis, and ER stress. Current therapeutic options are unsatisfactory, restricted to bone marrow transplant and gene therapy, for which most patients do not qualify. The encouraging results of plasma exchange (PE) with albumin replacement for Alzheimer's Disease prompted us to start this study. Our rationale is the following: In plasma, VLCFA are transported by lipoproteins and albumin. Albumin is the major transporter of fatty acids (FA) to the brain. ABCD1 deficiency induces inflammation and increases blood-brain barrier leakage, which could facilitate increased permeability to albumin. We posit that replacement of albumin would lower VLCFA levels in plasma through peripheral sink mechanisms, diminishing the quantity of VLCFA reaching the brain, and would prevent lipid peroxidation. A pilot proof-of-concept study in 5 X-ALD patients will be carried out to replace endogenous albumin through PE applied, once a week the first month and monthly for 5 months. A 6 months follow-up after the end of the treatment will be carried out.

NCT ID: NCT03864523 Completed - Clinical trials for X-linked Adrenoleukodystrophy

Effect of Pioglitazone Administered to Patients With Adrenomyeloneuropathy

XAMNPIOP2011
Start date: January 2016
Phase: Phase 2
Study type: Interventional

X-linked adrenoleukodystrophy is a rare, demyelinating and neurodegenerative disorder, due to loss of function of a fatty acid transporter, the peroxisomal ABCD1 protein. Its more frequent phenotype, the adrenomyeloneuropathy in adults, is characterized by axonal degeneration in spinal cord, spastic paraparesis and a disabling peripheral neuropathy. Actually, there is no efficient treatment for the disease. The work of the researchers in the last twelve years dissecting the physiopathological basis of the disorder has uncovered an involvement of the early oxidative stress in the neurodegenerative cascade and mitocondrial depletion. In a preclinical trial they have observed that pioglitazone, a PPARγ/PGC-1α axis metabolic activator with immunomodulatory, anti-inflammatory and antioxidant response regulator properties, efficiently reverse the clinical symptoms and the axonal degeneration in the mouse model for the disease and normalize stress and mitochondrial depletion biomarkers. The researchers will test the effectiveness of the drug in terms of motor function and correction of oxidative damage markers in proteins and DNA and inflammation markers in an open trial. Fifteen-twenty patients will be included and clinically explored and assessed in the HU of Bellvitge and the HU of Donostia using clinical scales for spasticity, evoked potentials, electroneurinograms and cranial RMN. The information will be collected in a data base that will be of great value to improve the present attention and the future follow-up of the patients and to facilitate their inclusion in therapeutic randomized, double blind, against placebo, multicentric and international clinical trials.

NCT ID: NCT03627416 Completed - Clinical trials for Hereditary Spastic Paraplegia

Repetitive Transcranial Magnetic Stimulation as Therapy in Hereditary Spastic Paraplegia and Adrenomyeloneuropathy

Start date: January 9, 2017
Phase: N/A
Study type: Interventional

Hereditary spastic paraplegia (HSP) is the group of inherited disorders, characterized by progressive gait disturbance. There is no established therapy. Adrenoleukodystrophy (AMN) is an x-linked hereditary disease. One of its form, the adrenomyeloneuropathy has the same symptoms as HSP. Current therapeutic options for AMN are very limited. Repetitive Transcranial Magnetic Stimulation (rTMS) is a noninvasive method of modulation of brain plasticity. The purpose of this study is to compare the effectiveness of rTMS in improving the HSP- and AMN-related gait disturbance and other symptoms with sham stimulation. Intervention will include five daily sessions. In each session 1500 magnetic pulses will be administered to each of both primary motor areas for lower extremities. Assessment of gait and of strength and spasticity of lower extremities will be made before and after therapy, as well as two weeks later.

NCT ID: NCT03047369 Recruiting - Clinical trials for Adrenoleukodystrophy

The Myelin Disorders Biorepository Project

MDBP
Start date: December 8, 2016
Phase:
Study type: Observational [Patient Registry]

The Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago. Researchers working in the biorepository hope to use these materials to uncover new genetic etiologies for various leukodystrophies, develop biomarkers for use in future clinical trials, and better understand the natural history of these disorders. The knowledge gained from these efforts may help improve the diagnostic tools and treatment options available to patients in the future.

NCT ID: NCT02961803 Completed - Clinical trials for Adrenoleukodystrophy

MD1003-AMN MD1003 in Adrenomyeloneuropathy

Start date: October 2014
Phase: Phase 2/Phase 3

The primary objective of the trial is to demonstrate the superiority of biotin at 300 mg/day over placebo in the clinical improvement (walking tests) of patients with adrenomyeloneuropathy

NCT ID: NCT02699190 Active, not recruiting - Clinical trials for Adrenoleukodystrophy

LeukoSEQ: Whole Genome Sequencing as a First-Line Diagnostic Tool for Leukodystrophies

Start date: January 6, 2017
Phase:
Study type: Observational

Leukodystrophies, and other heritable disorders of the white matter of the brain, were previously resistant to genetic characterization, largely due to the extreme genetic heterogeneity of molecular causes. While recent work has demonstrated that whole genome sequencing (WGS), has the potential to dramatically increase diagnostic efficiency, significant questions remain around the impact on downstream clinical management approaches versus standard diagnostic approaches.
