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.
A wide spectrum of methods is used to image brain activation in vivo. It can be directly detected by neurons electrical activity imaging (cortical simulation mapping, calcium imaging, voltage sensitive dyes) or indirectly by imaging hemodynamic changes induced by the neurovascular coupling in the vessels surrounding the activated neurons (intrinsic optical imaging, photoacoustic imaging, positron emission tomography (PET), functional magnetic resonance imaging (fMRI)). Ultrasound as the potential to complement these functional imaging techniques at low cost. Ultrasound imaging can do real-time in-depth imaging of brain. However, its use to imaging of major vessels has been limited until now due to its poor sensitivity. To overcome this limitation functional ultrasound (fUS) was developed in Institut Langevin since 2011. This technique enables high spatio-temporal resolution imaging of whole-brain microvasculature dynamics in response to brain activation without the need of contrast agent. This fUS method relies on a new power Doppler imaging sequence sensitive enough to detect blood flow in most of cerebral vessels (arterioles, big venules and larger vessels). Repeating the acquisition of such ultrasensitive Doppler images over time enables to follow flow dynamics in such vessels modulated by local neuronal activity. Applied to the rat brain, fUS was proved able to map brain activation at high spatiotemporal resolution and high signal to noise ratio. The aim of this study is now to apply fUS on human brain in intraoperative condition. The main objective of this study is to find activation maps through intraoperative ultrasensitive Doppler compared to gold standard cortical simulation mapping and functional MRI. Secondly the investigators want to test sensitivity of this new Doppler mode. fUS method will be used for different types of stimuli and intensity and the investigators will do some control acquisitions. Blood vessel density observed with a conventional Doppler will be compared to the one measured with the ultrasensitive Doppler to prove that this new Doppler mode enhance micro vessel visualization.
Determine the PK and safety and tolerability of aztreonam-avibactam (ATM-AVI) in the treatment of hospitalized adults with cIAI
Part A: The study is a double-blind, randomized, single ascending doses, study in 24 healthy elderly male and female volunteers. Each subject will be randomized for two subsequent doses in three cohorts. Part B: The study is a double-blind, randomized, multiple ascending doses study in 36 healthy elderly male and female volunteers. Subjects will be randomized to receive study product or placebo for 28 days.
This study will determine the pharmacokinetic profile of the salbutamol concentration in the urine while athletes are resting or during exercise.
This study evaluates the effect of iron chelation as a therapeutic strategy to slow the progression of Parkinson's disease. Half of participants will receive the deferiprone to 15 mg / kg twice daily morning and evening (30mg / kg per day), while the other half will receive a placebo. The treatment lasts nine months.
Brief Summary: In schizophrenia, dislocation of psychic functions involving a loss of contact with reality is frequently found. A fragmentation of motor and sensory perceptions could be held responsible. However, automatic integration between perception and action is the necessary condition to be in "relationship with the world." Affordance is the experimental link between object perception and potentially associated actions (Gibson, 1977, 1979) explored by Stimulus Response Compatibility (SRC) paradigm. With Tucker & Ellis sensory motor compatibility task (1998), with a modified response device (responses given with grasp), we study the impact of motor activation on these affordance effects. In this study, a group of controls will also be included in order to understand, as precisely as possible, the mechanisms involved (i.e., interference between the perception of the object and the response gesture).
NOTE: The study data was transferred to zr pharma& following the divestment of Panobinostat to pharma&. Prior to study completion under the sponsorship of Secura Bio, the study was initiated and conducted in part under the sponsorship of Novartis. The purpose of this study is to investigate the safety and efficacy of three different regimens of PAN (20 mg TIW, 20 mg BIW, and 10 mg TIW) in combination with s.c. BTZ and Dex and to provide exposure, safety and efficacy data to identify the optimal regimen of PAN in a randomized, 3-arm parallel design. This study will also assess the impact of administering s.c. BTZ (in combination with PAN and Dex) twice weekly for 4 cycles, and then weekly starting from Cycle 5 until disease progression in patients ≤ 75 years of age. Patients > 75 years of age will receive for the entire treatment period s.c. BTZ weekly (in combination with PAN and Dex) until disease progression. Patients will be treated until disease progression or until they discontinue earlier due to unacceptable toxicity or for other reasons. Patients who discontinued study treatment for reasons other than disease progression will be followed for efficacy every 6 weeks. All patients will be followed for survival until the last patient entering long-term follow-up has completed a 3-year survival follow-up or discontinued earlier.
the decrease in thoracopulmonary compliance after cardiac surgery is well known . The investigators hypothesize that the major factor determining pulmonary outcome after cardiac surgery is the alteration of pulmonary compliance during cardiopulmonary bypass(CBP) and that this alteration is due to CBP itself through pulmonary blood emptying.
In France, about 1 million people 65 and older are diagnosed with dementia syndrome characterized by cognitive decline and impairment of functional capacity. The assessment of the level of functional autonomy is therefore an essential step in monitoring patients in Memory Clinic and can be estimated by the Lawton IADL questionnaire, assessing the patients' ability to perform daily tasks. In the Memory Clinic, the first estimate of the level of patient autonomy is achieved during a face-to-face interview between their primary caregiver and a nurse, using the IADL questionnaire. This assessment should be renewed every year. The IADL questionnaire is part of the information that the memories consultations shall transmit to the Alzheimer's National Bank (BNA). However, current practice has shown that the systematic collection is problematic in the organization of Memory Clinic. It is thus expected to collect this questionnaire by phone in order to measure changes in the level of autonomy during the disease, and improve the completeness of this collection. A study is conducted with the main objective to measure the reliability of the assessment of IADL questionnaires conducted during a telephone interview with the caregiver of the patient, in comparison to the reference mode: the face-to-face interview with the caregiver. Materials and methods The experimental design of the study will be a randomized crossover trial (crossover), including 394 patients divided into two branches. In the first part, the collection of the IADL questionnaire will be performed according to the reference method in the consultation (face-to-face interview with the nurse), the measurement will be repeated at 1 month intervals by phone. In the second part the sequence of execution modes will be reversed. The reliability of the measurement of the level of autonomy will be studied by comparing repeated measurements based on handover modes. The correspondence between the repeated measures will also be considered in terms of patient characteristics. The feasibility of administration of the questionnaire by phone mode will be evaluated. Expected results The mode of administration by phone should allow to obtain a reliable measurement of the level of patient autonomy when the administration is carried out in a standardized way. The study should also identify patients and situations for which this method of administration by phone may be appropriate.
