Filter by:This trial is conducted in Europe. The aim of this trial is to compare the absorption of estradiol after a single dose of two 25 mcg estradiol vaginal tablets, produced at two different production sites, in postmenopausal women with atrophic vaginitis.
This is an open-label, dose escalation, safety, tolerability and pharmacokinetic study, where active study drug (QPI-1007) will be given to all patients who participate. This study will determine whether QPI-1007 is safe when it is injected into the eye. The study will also reveal if there are any side effects of the drug and how long it takes for the body to clear the drug.
Background: - Spinal muscular atrophy (SMA) is a degenerative and incurable neuromuscular disorder that is caused by mutations in the survival motor neuron gene, SMN1, found on chromosome 5. It is the leading inherited cause of infant mortality. SMA carriers (those who have the genetic mutation but do not have the disease) are often unaware of their status until they are tested. - Researchers have been studying the prevalence of SMA carriers in the general population, but most of the information collected has come from populations within the United States, Europe, and Asia. Very few studies have been performed in Africa. Furthermore, this information does not provide much information regarding carrier frequency based on ethnic background and ancestry. To address this problem, researchers are interested in studying the prevalence of the SMA genetic mutation in the sub-Saharan nation of Mali. Objectives: - To collect blood samples for use in studying genetic data related to spinal muscular atrophy. Eligibility: - Healthy volunteers who are at least 18 years of age. - Volunteers will be of Malian ancestry and nationality. Study Location: -<TAB>Bamako, Mali, West Africa Design: - The study will first collect blood samples from a small group of volunteers to run initial SMA carrier testing and resolve any technical difficulties before continuing with the study. - Participants will complete questionnaires about their personal and family medical history, including questions about illnesses, stillborns, and miscarriages, and then will provide blood samples for genetic research and testing.
Background: Multiple System Atrophy (MSA) is an atypical parkinsonian syndrome including cerebellar impairment and poor response to dopatherapy. The objective of the study is to assess right-hand motor activation in MSA patients before and after an acute levodopa challenge and to compare these data with those obtained in patients with Parkinson Disease (PD) and healthy volunteers (HV). Methods: Eighteen MSA patients, eight PD patients and 10 age-matched HV will be included. rCBF measurements with H215O PET will be performed at rest and during a right hand movement. Statistical parametric mapping will be used to analyze motor versus rest in OFF and ON condition and effect of levodopa on motor activation. Hypothesis: MSA and PD patient should recruited different motor networks.
The purpose of this study is to determine if the treatment with valproic acid can increase the muscle strength and motor ability of children with spinal muscular atrophy.
The purpose of this study is to determine the safety and tolerability of multiple doses of RN6G in subjects with advanced dry, age-related macular degeneration including geographic atrophy.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of the investigational drug ACU-4429 in subjects with geographic atrophy.
To test the clinical effect of rasagiline on subjects with MSA of the parkinsonian subtype.
The Phase Ia, open-label, multicenter study will consist of a single-dose, dose-escalation study of the safety, tolerability, pharmacokinetics, and immunogenicity of an intravitreal (ITV) injection of FCFD4514S in patients with Geographic Atrophy (GA).
The primary objective is to determine the pharmacokinetics, safety and tolerability of SRT2104 in healthy elderly subjects following single and 28 days dosing. The secondary objectives of the study are: 1. To contrast changes in leg muscle function following repeat doses of SRT2104 or placebo: Endurance exercise tolerance 31P MRS measures of mitochondrial oxidative capacity in the gastrocnemius muscle 2. To test for a change in the ratio of visceral to subcutaneous body fat following repeat doses of SRT2104 relative to placebo using MRI 3. To estimate any changes in insulin sensitivity (using mOGTT) following repeat doses of SRT2104 or placebo 4. To test for dose-related effects on the exploratory pharmacodynamic measures above
