Active clinical trials for "Amyotrophic Lateral Sclerosis"

The investigators laboratory has been studying families with a history of ALS for more than 30 years and is continuing to use new ways to understand how genes may play a role in ALS, motor neuron disease and other neuromuscular disorders. The purpose of this study is to identify additional genes that may cause or put a person at risk for either familial ALS (meaning 2 or more people in a family who have had ALS), sporadic ALS, or other forms of motor neuron disease in the hopes of improving diagnosis and treatment. As new genes are found that may be linked to ALS in families or individuals, the investigators can then further study how that gene may be contributing to the disease by studying it down to the protein and molecular level. This includes all forms of ALS, motor neuron disease and ALS with fronto-temporal dementia(ALS/FTD). We also continue to study other forms of neuromuscular disease such as Miyoshi myopathy, FSH dystrophy and other forms of muscular dystrophy by looking at the genes that may be associated with them. There have been a number of genes identified that are associated with both familial and sporadic ALS, with the SOD1, C9orf72, and FUS genes explaining the majority of the cases. However, for about 25% of families with FALS, the gene(s) are still unknown. The investigators also will continue to work with families already identified to carry one of the known genes associated with ALS.

The goals of this study are: (1) to better understand the relationship between the phenotype and genotype of amyotrophic lateral sclerosis (ALS) and related diseases, including primary lateral sclerosis (PLS), hereditary spastic paraplegia (HSP), progressive muscular atrophy (PMA), and frontotemporal dementia (FTD); and (2) to develop biomarkers that might be useful in aiding therapy development for this group of disorders.

The investigators seek to validate Slow Vital Capacity (SVC) measurement in seated and supine positions using conventional and portable spirometry.

Amyotrophic Lateral Sclerosis (ALS) is a progressive neurological disorder characterized by amongst others asymmetric muscle weakness, respiratory insufficiency and spasticity. The disease is usually fatal within 2-3 years and until now there is no cure. ALS patients are usually supported by a multidisciplinary team. One of the members of this team is the physical therapist. The aim of physical therapy might be to enhance or to preserve cardiovascular fitness and muscle strength. Some authors suggest, however, that a moderate to high intensive exercise programme might lead to overuse weakness (an undesired fast progression of muscle weakness). The primary objective of this study is therefore to investigate whether regular moderate to high intensity exercise program in ALS can maintain or optimize cardiorespiratory fitness and muscle strength. A secondary objective is to investigate whether such a programme leads to overuse weakness and if there is a positive influence on patient's disability, fatigue and quality of life.

This is a Phase 1, single-center study conducted in 2 parts: Part 1a, single ascending dose (SAD-TDU16519): Double-blind, randomized, placebo-controlled sequential ascending single oral doses including up to 6 cohorts. Each cohort will include 8 participants (6 receiving SAR443820 and 2 placebo). Part 1b (TDU16519): - Open label, single SAR443820 dose in one or two separated cohort(s) for SAR443820 measurements in CSF and in plasma. Part 2, multiple ascending dose (MAD -TDR16520): Double-blind, randomized, placebo-controlled, sequential ascending repeated oral doses for 14 days, including up to 4 cohorts. Each cohort will include 10 participants (8 receiving SAR443820 and 2 placebo).

Part 1: This is an open label, balanced randomized, single dose, 2-sequence, 2-period (period 1 and period 2), 2-treatment crossover (between Treatment A and Treatment B for Part 1), study part to determine the relative bioavailability of SAR443820 in tablet formulation versus capsule formulation under fasted conditions. Two treatments are as follows: Treatment A: SAR443820 - tablet formulation in fasted condition Treatment B: SAR443820 - capsule formulation in fasted condition Each administration will be a single dose of SAR443820 separated by a wash out of at least 5 days. Part 2: This is an open-label, balanced randomized, single dose, 2-sequence, 2-period (period 1 and period 2), 2-treatment crossover (between Treatment C and Treatment D for Part 2) study part to perform a preliminary assessment of the effect of a high-fat meal on pharmacokinetic parameters of single dose of SAR443820 in tablet formulation. Two treatments are as follows: Treatment C: SAR443820 - tablet formulation in fasted condition Treatment D: SAR443820 - tablet formulation in fed condition Each administration will be a single dose of SAR443820 separated by a wash out of at least 5 days. Participants are not allowed to participate in more than one part of the study. In both Parts 1 and 2, the assessment of pharmacokinetic, safety and tolerability are performed at each treatment period at baseline (prior single dosing) up to 48-hour postdosing in healthy adult male and female participants.

This clinical trial is a phase 1 study in which investigations with the weakly radioactive substance [18F]-RoSMA-18-d6 are being carried out for the first time. This radiolabeled substance will be used to study a specific protein in the brain and spinal cord of patients with ALS and healthy individuals. This particular protein, the cannabinoid type 2 receptor, is thought to play a role in the disease process of ALS. Furthermore, it is assumed that this protein is found more frequently in the brain and spinal cord of patients with ALS compared to healthy individuals. The following questions will be answered by this clinical trial. Is this protein found, as suspected, increased in the brain and spinal cord of ALS patients compared to healthy individuals ? Does the amount of this protein change during the course of the disease? Are there any correlations between the observed changes in the amount of protein and the assessment of the course of the disease?

This study will evaluate the pharmacokinetics and safety of GDC-0134 in healthy female volunteers of non-childbearing potential. The first part of the study will compare the bioavailability of a prototype capsule of GDC-0134 relative to an existing GDC-0134 reference capsule (Periods 1 and 2). The second part of the study will assess the effect of GDC-0134-in-applesauce preparation under fasting conditions, the effect of low and high fat foods as well as the effect of elevated stomach pH via pre-treatment with rabeprazole, a proton pump inhibitor (PPI), under fasted and high-fat meal conditions (Periods 3 and 4).

This first-in-human, double-blind, placebo-controlled Phase I study will be conducted in participants with amyotrophic lateral sclerosis (ALS) to explore safety, tolerability, and pharmacokinetic (PK) properties of GDC-0134. It will include three components: a Single-Ascending-Dose (SAD) stage, a Multiple-Ascending-Dose (MAD) stage, and an Open-Label Safety Expansion (OSE) stage.

Amyotrophic lateral sclerosis (ALS) is a lethal degenerative disorder that upper motor and lower motor neurons are destroyed in brain stem and spinal cord. Riluzole is the only therapeutic option now. Recently several studies have shown that stem cell transplantation is safe and can be effective in reduction of disease progression and increase of quality of life.
