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.
Aortic stenosis is one of the most common cardiology diseases. Trans aortic valve implantation (TAVI) has been developed since 2002, first to treat rejected patients from conventional surgery, then to treat high surgical risk patients and nowadays probably intermediate surgical risk patient. TAVI related complications are still recurrent and the investigators are searching a way to decrease them. One of them could be image fusion, since it may decrease radiation exposure and contrast agent use. It may also improve valve placement position leading to decreased complications. 40 prospective and consecutive patients will be included. Participants will be divided into two groups: the 20 first included will be control group, the 20 following patients will be the fusion group. For control group TAVI procedure will be the usual one, for fusion group the procedure will be the usual one with addition of computed tomography 3D images fusion with fluoroscopy 2D images. Main evaluation criteria will be radiation exposure, measured by dose area product (DAP). Secondary evaluation criterion will be procedural as contrast agent volume used, procedure duration, subjective usefulness of image fusion or procedure failure evaluated immediately after procedure. The investigators will also evaluated procedure induced complications as de novo pacemaker implantation, de novo left bundle branch, vascular complication, major bleeding, acute kidney failure, significant aortic regurgitation. These complications occurrence will be evaluated after 1 month follow up, during the usual following consultation.
Regulatory T lymphocytes play a major role in the protection from autoimmune pathology. Defects in immunosuppression mediated by these cells is therefore suspected to contribute to these diseases. This issue has very little been studied in humans.Regulatory T cells emigrated from the thymus will be isolated from the blood of patients and healthy controls. The repertoire of antigen-receptors will be analysed by high throughput sequencing and its diversity estimated using appropriate statistical models borrowed from ecology.
The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) in combination with daratumumab in participants with relapsed refractory multiple myeloma (rrMM). The primary outcome measure for this study is the assessment of Objective Response Rate (ORR) in participants with rrMM.
Social cognition concerns the understanding of how people think about others and how that, in turn, influences our behavior, feelings, and social interactions. schizophrenia social-cognitive impairment is profound (effect size D>1.2), medication resistant and critically limits functional well-being . Social cognition involves complex patterns of coordinated activity within numerous cortical and subcortical networks, making it a difficult target for clinical neuroscience investigation. Yet, prior research demonstrates that sensory-perceptual dysfunction in schizophrenia can upwardly generalize into higher-order social-cognitive impairment making perception a tractable and fruitful approach for studying social cognition in schizophrenia. Here, the investigators explore how distortions in perception of temporal coincidence can contribute to the aberrant inferences of physical causation and social agency.
This is a phase I/II, open label dose escalation study of multiple dose levels of NV1205 with a long-term treatment phase.
To investigate the safety and efficacy of abatacept with steroid treatment in comparison to steroid treatment alone in up to a 28 week taper of steroid treatment to sustain remission of Giant Cell Arteritis in adults.
The primary objective of this study is to compare an experimental organization for chemotherapy session planning based on early, standardized, and prioritized means of data transmission via secure e-mail (laboratory results) and the use of a smart phone (for clinical toxicity data) compared to the regular organization, in terms of the rate of prescriptions of chemotherapy prepared at the latest the day before a session and then administered in full (over a 6-month observation period) among colorectal cancer patients in need of cancer treatment in an outpatient setting.
Asthma is a major public health problem. The main treatments against asthma are delivered to the lung through several dry-powder inhaler such as Turbuhaler ®, Diskus® and the new Ellipta® device. In real life, patient's ability to handle a device is not routinely assessed by their practitioner. We hypothesized that many asthmatics cannot properly prepare and prime their device, which may alter the positive effects observed in clinical trials.
The supra ventricular tachycardia is the most common symptomatic arrhythmia in pediatrics. Amiodarone is an antiarrhythmic drug used in this indication. Pharmacokinetic, efficacy and safety data are not known in the pediatric population due to the lack of a suitable specialty available on the market. The development of an amiodarone oral solution formulation adapted to this age group should provide a therapeutic alternative and collect data on the pharmacokinetics, efficacy, acceptability and tolerability of the drug.
The initial hypothesis of this work is that the genesis and the evolution of the atheromatous plaque are partly controlled at the molecular level and in particular by the microRNAs through their role as regulator of the genes. The study of the tissue and serum profile over time of specific microRNAs involved in the regulation of atheromatous plaque correlated with clinical data and restenosis imaging will allow to define biological markers of restenosis in the patient with an arteritis of the lower limbs . This study is a pioneer in the field and it would be imprudent to conclude that a biomarker would be used clinically at the end of this work alone. Nevertheless this study will make a major advance in this topic, in vivo intervention studies with inhibition or over-expression of microRNA will obviously be necessary to confirm the use of these as biomarkers of arteritis of the lower limbs. Regular assay of reliable biomarkers in arterial patients will ultimately suggest early management to best adapt surgical and medical treatment.
