There are about 36633 clinical studies being (or have been) conducted in France. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The prevention of graft rejection after liver transplantation benefits nowadays from a variety of newly developed immunosuppressive agents. This allows more flexible and individualized immunoprophylaxis and gives an opportunity to reduce the long-term side effects (hypertension, renal failure, diabetes, etc.) of immunosuppression. The purpose of this study is to evaluate, in liver transplanted patients, if low doses of tacrolimus, given in combination with mycophenolate mofetil, can result in a lower rate of long-term side effects without increasing the rate of graft rejection.
Patients with congestive heart failure are usually treated with a combination of an ACE inhibitor (or an AT1 blocking agent), a diuretic and a beta-blocker. However, some patients remain symptomatic despite an optimal treatment with these drugs. In patients who also have coronary heart disease, nitrates or some calcium-channel blockers could help to relieve symptoms. Therefore, the aim of our study is to evaluate the additional benefit induced by a second generation calcium-channel blocker, amlodipine, in patients with chronic heart failure who remain symptomatic despite an optimal treatment.
The aim of this randomized study is to compare the effect of pioglitazone versus placebo on change in limb fat in HIV 1-infected patients treated with antiretroviral therapy for at least 6 months and with clinical lipoatrophy.
For HIV-infected individuals with highly resistant viruses, higher drug levels may be required to block the virus. This study investigates that concept by comparing the efficacy of standard fosamprenavir/ritonavir to an increased dose of boosted fosamprenavir and to a combination of fosamprenavir (increased dose)/lopinavir/ritonavir.
Evaluation of safety and efficacy of Tipranavir (TPV) boosted with Ritonavir (RTV) versus an active control arm (Lopinavir / RTV) in antiretroviral (ARV) therapy naïve HIV-1 infected patients
The DNA and Cell Bank of Instituts Federatifs de Recherche (IFR) of Neurosciences has been running for the last 15 years at the Institut National de la Santé Et de la Recherche Médicale (INSERM) Unit 679 (former unit 289). Since its creation, this structure has been the support of research projects in genetics for neurological and psychiatric disorders. The cohorts established have led to discoveries in monogenic disorders, such as cerebellar ataxias, spastic paraplegias, frontotemporal dementias, epilepsies, Parkinson’s and Alzheimer’s disease, Charcot-Marie-Tooth disease and related entities. The research projects based on the study of the genetic bases in Parkinson’s disease and epilepsies are especially developed for this grant. Concerning Parkinson’s disease, the project is based on the extension of the existing cohort throughout the French Parkinson’s Disease Study Group network. Concerning epilepsies, this project is the occasion to build this network with the constitution of a new cohort. The specific aims of the scientific projects are the following for Parkinson’s disease: - to evaluate the frequency, the nature and the phenotype associated with parkin mutations in familial or sporadic forms of the disease, according to the age at onset, and - to identify the genetic susceptibility factors in Parkinson’s disease with the study of affected sibpairs and with case/controls association studies. For epilepsies, the aims are: - to evaluate the frequency, the nature and the phenotype associated with SCN1A, SCNab and GABR2 gene mutations in familial or sporadic forms of the affection associated with febrile seizures, and - to search for an intervention SCN1A, SCN1B and GABRG2 as susceptible genes in these forms of epilepsies.
Parkinson’s disease is one of the most frequent neurodegenerative diseases, and for which the mechanisms remains unknown. Since the implication of susceptibility factors is highly suspect, we have recently shown that one monogenic form due to alterations in the Parkin gene was responsible for an important proportion of early onset familial and isolated cases. Nevertheless, it not has been determined yet the relationship between idiopathic Parkinson’s disease and secondary Parkinson’s disease with a Parkin gene mutation at the clinical, neuropsychological, metabolic and physiopathological levels. For establishing phenotype-genotype correlations, we propose to compare the phenotype of patients carrying a Parkin mutation (parkin « + », n=25) to those of early onset parkinsonians without a Parkin mutation (Parkin ” - ”, n = 25), and for some aspects (neuropsychological, behavioural and psychiatric evaluations) to the healthy brothers and sisters of Parkin cases “+”(n = 25). The evaluation will carry on the clinical aspects (quantification of the parkinsonian syndrome and reactivity to levodopa, neuropsychological, behavioural and psychiatric evaluations), molecular (types of abnormalities in the Parkin gene) and metabolic (PET – tomography by positron emission) of the disease. Parkinson’s disease caused by Parkin gene mutations is associated with an important and homogeneous loss of dopaminergic neurons of the substantia nigra pars compacta, which is different from those observed during the idiopathic Parkinson’s disease. The corresponding dopaminergic deficit should be associated with an excellent reactivity to levodopa, to a cognitive deficit and to behavioural and/or psychiatric attitudes, in relation with the massive alteration of dopaminergic efferences. This multidisciplinary approach on Parkin cases will be performed in the centers for of clinical investigations of Grenoble and Paris, with the help of the French Parkinson’s Disease Study Group, and two centers for TEP (Lyon and Orsay). This project will allow to a better definition of diagnostic criteria of Parkin « + » cases, which will help for the molecular diagnosis in early onset cases, and will study precisely the clinical, psychiatric and metabolic consequences of a massive and homogeneous dopaminergic denervation, which seems to be different of idiopathic Parkinson’s disease.
Comparing the short-term efficacy of rofecoxib versus placebo. Patients receive rofecoxib or placebo or diclofenac and fill out a patient diary on daytime pain severity during daily activities, night pain severity, and acetaminophen/paracetamol intake.
This study is a multicentric randomized trial evaluating the efficacy of the combination R-ACVBP in patients 18 to 65 years with low risk localized diffuse large B-cell lymphoma.
Gait disorders and falls are frequent in patients with parkinsonian syndromes. In patients with Parkinson's disease (PD), these signs occurred later during the course of the disease in comparison to patients with other degenerative parkinsonian disorders. The pathophysiology of these symptoms are still not fully understood. Gait initiation challenges the balance control system as the body moves from an upright stable static posture to a continuously unstable gait. The aim of this study is to analyse the gait initiation process in patients with parkinsonian disorders.
