Assess the efficacy and the safety of olesoxime in SMA type 2 or type 3 non ambulant patients aged 3-25 years
The purpose of this Phase III trial is to confirm the efficacy of intravaginal dehydroepiandrosterone (DHEA) in postmenopausal women with vaginal atrophy.
The purpose of this Phase III trial is to assess the long-term safety of intravaginal dehydroepiandrosterone (DHEA) in non-hysterectomized postmenopausal women with vaginal atrophy aged 40 to 75 years.
This is a Phase Ib/II, multicenter, randomized, single-masked, sham-injection-controlled study of safety, tolerability, and evidence of activity of FCFD4514S intravitreal injections administered monthly or every other month in patients with geographic atrophy.
The purpose of this study is to assess the efficacy and safety of Adapalene Gel 0.3% in the treatment of atrophic acne scars.
This study is being conducted to test whether exercise can be effectively used as an intervention to treat Spinal Muscular Atrophy (SMA). In order to answer this question, the investigators will enroll 14 subjects with SMA between ages 8 and 50 and ask them to complete an 18 month training schedule. At some points subjects will be asked to closely follow a specific training regimen and at other points they may be asked to exercise in the same manner they do normally. The exercises they will be asked to perform include biking on a stationary cycle and lifting hand weights. Subjects will be asked to come in to the clinic seven times over the course of the study to perform tests. These tests include motor function measures, a physical exam, questionnaires, a exercise capacity test which involves riding a stationary bicycle, and test where the subject is asked to walk as far as they can in six minutes. The main goal of the study is to see if the subjects who participate in the exercise protocol have larger increases in the distance they can walk in six minutes than those who do not.
This is a French national trial, conducted using a double-blind, placebo-controlled, randomised design involving 15 centers and 88 patients of both sexes. The primary objective of the trial is to evaluate the effect of a selective inhibitor of serotonin reuptake, the Fluoxétine, at a higher dose (40 mg/day) than usually recommended for depressed patients, after three months in patients suffering from an atypical Parkinson's disease called Multiple System Atrophy, compared to the placebo effect. Secondary objectives of the trial are the evaluation of the effects of Fluoxétine after six weeks at the dose of 20 mg/day, after six months at the dose of 40mg/day, and assess the effects on mortality, quality of life, autonomic disorders, particularly orthostatic hypotension, mood and others symptoms such as sleep, apathy, pain and fatigue.
Multiple system atrophy (MSA) is a sporadic neurodegenerative disorder of the adult associated to a poor prognosis. MSA is clinically characterized by the association of extra-pyramidal, dysautonomic, cerebellar and pyramidal symptoms. Histological and biological studies have raised the hypothesis that, beside the well known dopamine deficiency, some of the symptoms could be related to a dysfunction in serotoninergic neurotransmission. Serotonin is involved in the modulation of several functions impaired in MSA, such as mood, motricity or sleep. The recent description of an association between loss of brainstem serotonin neurons and sudden death in patients with MSA reinforced the hypothesis of a critical role played by this neurotransmitter in the pathophysiology of this disease. Autoreceptors called 5-HT1a are strongly involved in the regulation of serotonin neurotransmission. During the last years several radio-ligands allowing in vivo PET quantification of 5-HT1a receptors, such as 18F-MPPF (4-(2'-methoxyphenyl)-1-[2'-(N-2''-piridinyl)-p-fluorobenzamide]methylpiperazine), were developed. Moreover, the investigators recently demonstrated the ability of this brain functional imaging method to investigate, in healthy volunteers, the functional properties of 5-HT1a autoreceptors through an evaluation of their desensitization after a single oral dose of fluoxetine.
The first objective is to asses influence of age on amyloid load measured by PET imaging using Pittsburgh B compound (PiB) radio-tracer, in Alzheimer's disease(AD). This will allow the determination of brains age-specific deterioration factors by comparing Early onset AD (EOAD), Late onset AD (LOAD)and atypical focal cortical AD (PCA and LPA). The amount of brain lesions in AD patients is estimated by: 1. measuring the rate of cortical brain atrophy, 2. FDG imaging of glucose metabolism reflecting neuronal activity, and 3. for patients who benefited from a lumbar puncture; Cortical-spinal fluid (CSF) amounts of amyloïd and tau proteins are measured.
