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.
Multiple sclerosis (MS) in children, a rare disease, follows a relapsing remitting course with a shorter interval between the first 2 clinical events and higher annualized relapse rate as compared with MS in adults. Residual deficits following clinical events are less frequent. The vast majority of children and adolescents with MS are thought to have a greater potential for myelin repair than adults. However convincing data in the literature to support this hypothesis are lacking, because until now no imaging technique has been validated to measure remyelination in vivo.
In image-guided radiotherapy (IGRT), the repeated and increasingly intensive use of on-board positioning imaging, using 2D or 3D Mega-Volt (MV) or kilo-Volt (kV) imaging devices (cone-beam or CBCT scanners), is leading the international medical community to question the potential impact of these additional doses delivered to the patient, especially in at-risk populations such as children and young adults. The doses delivered to the patient by positioning imaging are still relatively unknown, due to the lack of experimental means and software available in clinical routine to easily and accurately evaluate these doses. The main objective is to estimate by personalized Monte Carlo calculation the physical doses delivered to the patient's organs by the onboard imaging systems during their radiotherapy treatment. The obtained imaging doses will be compared according to different irradiation scenarios commonly used in clinical routine as well as according to the treated location.
This is a Phase 2b study investigating the efficacy and safety of pirepemat as adjunct therapy on falls frequency in patients with Parkinson disease. Pirepemat is taken for 84 days.
Patients hospitalized in the ICU are likely to develop sarcopenia due to a progressive and generalized decrease in muscle mass that is responsible for generalized muscle weakness known as resuscitation neuromyopathy. This neuromyopathy is known make weaning from mechanical ventilation more difficult, which prolongs the hospitalization of patients in the ICU and in hospital. The factors identified as being partly responsible for this neuromyopathy are: immobilization, undernutrition, prolonged duration of mechanical ventilation, inflammation (notably secondary to sepsis), and multivisceral failure. These factors are essentially found in patients in septic shock, which represents about 20% of patients admitted to the ICU, with a mortality rate close to 50%. If the management of septic shock is now well codified (i.e. vascular filling, antibiotics and/or treatment of the infectious focus by surgery +/- organ replacement therapy) as well as the early rehabilitation of ICU patients, no treatments has yet been proven to be effective in limiting the appearance of resuscitation neuromyopathy. For the last ten years, research using electrostimulation (ES) to improve muscle contraction seems to give encouraging results, both for length of hospital stay and the duration of mechanical ventilation, notably through the preservation or a significant increase in muscle strength. On the other hand, other studies did not show a significant effect on muscle strength. These conflicting results are partly related to the heterogeneity of the populations included in the studies and to the different ES approaches used to assess and recondition motor function. In the present STIMUREA study, an original approach is proposed based on experimental research work carried out for many years within U1093 (Pr Charalambos Papaxanthis) which focuses on ES, not of the muscle surface as in most studies carried out in the ICU, but an approach based on ES of the motor nerve. Indeed, the intensity of ES used in previous studies was based on a maximum tolerated intensity leading to a direct recruitment of the most fatiguable motor units (via the activation of motor axons) but leading, in fine, to a decrease in muscle strength. The U1093 research team and previous studies have shown that protocols using high stimulation frequencies (100Hz) associated with pulse widths of 1ms and delivered at low intensities (5-10% of the maximum voluntary contraction, MVC) at the level of the motor nerve, could increase the force developed during the contraction, while decreasing the discomfort induced by the high intensities. This increase in force would be due to the indirect activation of motor neurons via large diameter sensory afferents, thus leading to a recruitment of motor units similar to that observed during voluntary contractions. In a very recent study conducted in our laboratory (INSERM U1093), it was demonstrated that the application of ES to the motor nerve at low intensities did not induce discomfort in healthy subjects, but could induce substantial strength gains (+25%) with adaptations occurring at both in the muscles and the nerves. The proposed study is an innovative, randomized, pilot study based on motor nerve ES in a highly selected population of ICU patients in septic shock and therefore with a high risk of developing neuromyopathy, which is responsible for a significant increase in morbidity and mortality.
Chronic inflammatory demyelinating polyradiculoneuritis (CIDP) is an autoimmune disorder of the peripheral nervous system, most commonly affecting the myelin sheath. The pathophysiology of CIDP is not completely understood, but both humoral and cellular immunity appear to be involved in the genesis of this disease. Some diseases are particularly associated with CIDP such as diabetes, monoclonal gammopathies and hematological diseases. CIDP can occur before, after or simultaneously with the onset of systemic diseases. The systemic diseases most often seen in association with polyneuropathies are lupus, Gougerot-Sjögren's syndrome and sarcoidosis. Ultrasound of peripheral nerves is a useful and accessible tool. In CIDP, this examination can reveal diffuse or segmental nerve hypertrophy. In addition to the size of the nerve, this exploration analyzes the echogenicity and the aspect of the different fascicles within the nerve. S. Goedee et al have shown that nerve ultrasound has very good diagnostic parameters and low interobserver variability in the diagnosis of CIDP. F. Härtig et al suggests that nerve ultrasound can predict the therapeutic response and describes 3 main patterns: hypoechoic enlargement (active inflammation), nerve enlargement with hyperechoic add-on fascicles (axonal degeneration) and almost no enlargement ("cured" CIDP).
