NCT ID: NCT04687007 Completed - Clinical trials for X-linked Adrenoleukodystrophy

SMART-ALD - A New Lifestyle Intervention to Improve Quality of Life in Women With X-linked Adrenoleukodystrophy (X-ALD)

Start date: May 20, 2022
Phase: N/A
Study type: Interventional

X-linked Adrenoleukodystrophy (X-ALD) is one of the most frequent inborn error of metabolism caused by mutations in the ABCD1 gene, which codes for the transporter of saturated very long-chain fatty acids (VLCFA) for peroxisomal degradation, thus causing their toxic accumulation in body fluids and tissues. The clinical spectrum ranges from adrenal insufficiency without neurological symptoms to a rapidly progressive, fatal cerebral demyelinating disease that may occur in childhood as well as later in life. The most frequent phenotype in adulthood is adrenomyeloneuropathy (AMN), a slowly progressive myelopathy and peripheral neuropathy, which may also be prevalent in up to 80% of females carrying the X-ALD gene defect. Since signs and symptoms in females are usually milder and with a later onset, they are frequently underestimated, overlooked or misinterpreted, e.g. as Multiple Sclerosis. Consequently, many women with X-ALD do not receive adequate treatment. Against this background, the development of new therapeutic interventions with the help of eHealth technology (e.g., counselling and treatment via digital communication tools) is of particular relevance, as it provides cost-effective, regular care even for patients who live remote from Leukodystrophy clinics. The aims of this study is to evaluate the effectiveness of a multi-approach intervention ("SMART-ALD") on physical and mental well-being and quality of life in n=30 X-ALD symptomatic heterozygous females compared to a waiting list control group (n=30) using electronic health (ehealth) technology.

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: NCT03852498 Completed - Clinical trials for Cerebral Adrenoleukodystrophy (CALD)

A Clinical Study to Assess the Efficacy and Safety of Gene Therapy for the Treatment of Cerebral Adrenoleukodystrophy (CALD)

Start date: January 24, 2019
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the efficacy and safety of Lenti-D Drug Product (also known as elivaldogene autotemcel or Skysona, hereafter referred to as eli-cel) after myeloablative conditioning with busulfan and fludarabine in participants with CALD. A participant's blood stem cells will be collected and modified (transduced) using the Lenti-D lentiviral vector encoding human adrenoleukodystrophy protein. After modification (transduction) with the Lenti-D lentiviral vector, the cells will be transplanted back into the participant following myeloablative conditioning. Enrollment and treatment in Study ALD-104 have been completed and further enrollment in this study is not expected, although participants follow-up remains ongoing in the long-term follow-up Study LTF-304 (NCT02698579).

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.
