12 Clinical Trials for Various Conditions
This is a Phase 1, cross-over, 2-part study for pharmacokinetic (PK) assessment of SAR443820 when co-administered with cytochrome P450 3A4 (CYP3A4) inhibitors (erythromycin ethyl succinate (EES) in Part A and possibly itraconazole in Part B). In Part A, the objective is to assess the effects of repeated administration of EES as CYP3A4 inhibitor, on the PK profile of a single oral dose of SAR443820 tablet in healthy male and female participants. In Part B, the objective is to assess the effects of repeated administration of itraconazole on the PK profile of a single oral dose of SAR443820 capsule in healthy male participants. Part A includes a screening period, Period 1 (SAR443820), a wash-out period and Period 2 (SAR443820 + EES). Part B includes a screening period, Period 1 (SAR443820), a wash-out period and Period 2 (SAR443820 + itraconazole). The washout period between single SAR443820 administration in Period 1 and the start of dosing with EES (Part A) or itraconazole (Part B) in Period 2 is at least 4 days. The study duration is approximately 7 weeks for each Part A and Part B. The treatment duration is: * For SAR443820 (both Part A and Part B): 1 day in each Period; single dose of SAR443830 on Period 1 (P1)-Day 1 and on Period 2 (P2)-Day 6 for each Part. * For EES (Part A): 9 days of treatment in Period 2 with P2-Day 1 starting at least 4 days after P1-Day 1. * For itraconazole (Part B): the treatment duration lasts 11 days in Period 2 and it is fixed once the results of Part A are issued, P2-Day 1 starting at least 4 days after P1-Day 1.
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 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).
This is a Phase 1/2 study to evaluate the safety and tolerability of 18F-OP-801 in subjects with ALS, AD, MS, PD and age-matched HVs. 18F-OP-801 is intended as a biomarker for PET imaging of activated microglia and macrophages in regions of neuroinflammation.
The primary objective of this study is to evaluate the effect of supratherapeutic exposures of ALS-008176 on the QT/ corrected QT interval (QTc) interval in healthy participants (Panel 2).
The primary objectives of this study are to investigate the safety and tolerability of VRG50635 and to determine how VRG50635 is absorbed by the body.
The primary purpose of this study is to evaluate the safety and tolerability of prosetin in healthy volunteers and participants with ALS.
To evaluate the PK, safety and tolerability of orally administered NPT520-34 in healthy subjects at single and multiple doses that may be therapeutically relevant.
The overall goal of this protocol is to evaluate microglial activation in the brain using \[18F\]PBR06 in patients with amyotrophic lateral sclerosis (ALS).
To evaluate whether dexpramipexole prolongs the QTc interval when orally administered to healthy volunteers.
This study will test whether primary lateral sclerosis (PLS) and amyotrophic lateral sclerosis (ALS) affect parts of the brain responsible for thinking, planning, memory and emotion. Healthy volunteers 18 years of age and older and patients with PLS and ALS may be eligible for this study. Participants undergo the following procedures: * Rating motor function: Subjects are asked to contract certain muscles in the face, arms and legs, to tap their finger on a keyboard rapidly, to walk 20 feet, and to read a paragraph out loud. * Electroencephalography (EEG): The electrical activity of the brain (brain waves) is recorded while subjects tap their finger very slowly. For this test, electrodes are placed on the scalp using a cap or an adhesive substance. A conductive gel is used to fill the space between the electrodes and the scalp to ensure good contact. * Surface electromyography (EMG): The electrical activity of the muscles is measured. Electrodes filled with a conductive gel are taped to the skin over the muscle tested. * Neuropsychological testing: Testing may include questionnaires, pen-and-paper or computerized tests, and motor tasks. * Magnetic resonance imaging (MRI): MRI uses a strong magnetic field and radio waves to produce images of the brain. The subject lies on a table that slides into the scanner. Scanning time varies from 20 minutes to 3 hours, with most scans lasting 45-90 minutes.
This study will use a magnetic resonance imaging technique called nuclear magnetic spectroscopy (H-MRS) to define the pathology and progression of primary lateral sclerosis, hereditary spastic paraplegia and amyotrophic lateral sclerosis and assess the usefulness of this technique in evaluating patients' response to therapy. H-MRS will be used to examine metabolic changes in the parts of the brain and spinal cord (motor cortex and corticospinal tract) involved in movement. Normal volunteers and patients with primary lateral sclerosis, hereditary spastic paraplegia or amyotrophic lateral sclerosis between 21 and 65 years of age may be eligible for this study. Participants will have up to five H-MRS studies, including baseline and follow-up tests. For this procedure, the subject lies on a stretcher that is moved into a strong magnetic field. Earplugs are worn to muffle the loud knocking noise that occurs during switching of radio frequencies. The subject will be asked to lie still during each scan, for 1 to 8 minutes at a time. Total scanning time varies from 20 minutes to 2 hours, with most examinations lasting between 45 and 90 minutes. Communication with the medical staff is possible at all times during the scan.
