NCT ID: NCT03445845 Recruiting - Clinical trials for Axial Spondyloarthritis

Rotation or Change of Biotherapy After TNF Blocker Treatment Failure for Axial Spondyloarthritis

Start date: December 14, 2018
Phase: Phase 4
Study type: Interventional

Axial spondyloarthritis (axSpA) is a chronic inflammatory disease characterized by inflammatory arthritis and enthesitis involving the spine. AxSpA prevalence is around 0.17% of the French population. Tumor necrosis factor (TNF) was the first target defined in axSpA. Since one third of axSpA patients failed to the first TNF blocker, many axSpA patients received a second biological Disease-Modifying AntiRheumatic Drugs (bDMARDs). Until few months, the only choice was to use a second TNF blocker.Since 2003, pharmaceutical companies investigated efficacy of TNF blockers already used in rheumatoid arthritis. Etanercept is a fusion protein with TNF receptor type II p75 and IgG1 Fc fragment, whereas adalimumab, infliximab, and golimumab are monoclonal antibodies. Certolizumab is a fusion between a fab fragment targeting TNF and a Peg fraction. All demonstrated efficacy versus placebo in a randomized double blinded study In case of failure to the first TNF blockers, rheumatologists will follow the "Treat-to-Target" principle. This approach already demonstrated its benefit in rheumatoid arthritis or in psoriatic arthritis. This concept was also suggested for axSpA with low levels of evidence and recommendation. So rheumatologist will provide the best treatment in case of failure to the first TNF blockers, which is a daily clinical situation. Since few months, rheumatologists have the choice between targeting IL-23/17 axis compared to a second TNF blocker.

NCT ID: NCT03313505 Not yet recruiting - Clinical trials for Mild Traumatic Brain Injury

PROtein S100B for Mild Trauma of the HEad in Emergency Patients

Start date: November 2017
Phase: N/A
Study type: Observational

Brain injury is a frequent purpose for consultation in emergency services. Management of brain injury is time and resource consuming, combining clinical monitoring and imaging. The stage prior to the management of the victims of brain injury is stratification of the severity, potential or proven. Severe brain injury requires emergent brain CT-scan, ideally within one hour of the first medical contact. Patients requiring this strategy present with focused neurological deficit, Glasgow score <15 to 2 hours after the trauma, suspicion of open fracture of the skull or dish pan fracture, any signs of fracture of the skull base (hemotympanum, bilateral peri-orbital ecchymosis), otorrhea or rhinorrhea of cerebrospinal fluid, more than one episode of vomiting in adults, and posttraumatic convulsion. Patients benefiting from anticoagulant therapy are included in this category. Victims of brain injury that do not fall into this category are considered less critical. By definition, mild traumatic brain injury : - a trauma of the cephalic extremity : - whose Glasgow score (30 min after the trauma or during the consultation) is 13-15, - associated with one or more of the following: confusion; disorientation; loss of consciousness of 30 min or less; post-traumatic amnesia of less than 24 hours; other transient neurological abnormalities (focal signs, epileptic seizures, non-surgical intracranial lesion). Among these patients, some are considered at risk of developing intracerebral lesions. Nevertheless, it should be noted that the prevalence of hemorrhagic complications is radically different between patients with a Glasgow score of 13 and those with a score of 15. Thus, the recommendations suggest a brain scan without injection of contrast media within 4 to 8 hours for patients with the following characteristics : - a retrograde amnesia of more than 30 minutes, - a loss of consciousness or amnesia associated with: - either a risk mechanism (pedestrian overturned by a motor vehicle, ejection of a vehicle, falling by more than one meter), - or an age> 65 years, - or coagulation disorders, including the use of platelet aggregation therapy. Patients who fall outside this definition are considered low risk of complication and should not benefit of imaging. Data from the scientific literature show that an early brain CT-scan allows identification of post-traumatic lesions in this population. Nevertheless, organizational problems, including the availability of the imaging, radiation, and disruption of surveillance related to patient displacement, are limitations to this strategy. In contrast, the low cost-effectiveness of CT scan is often advocated in patients with mild traumatic brain injury. For example, in the Octopus study, 52 of 1316 patients who received CT scan after mild head trauma had an intracerebral lesion. Among these patients, 39 (3%) had intracerebral lesion related to trauma; for 13 (1%) patients, the link with the trauma was uncertain. In fact, the search of alternatives for a safer, more conservative, more efficient practice, one of the objectives of which is to limit the undue use of cerebral scanning. Thus, many teams have been interested in the use of biological variables to guide the decision to use imagery. Among candidate biomarkers, the S100B protein has been the subject of many evaluations which allow it to be used in current practice. Indeed, the increase of the S100B protein carried out within 3 hours following a mild head trauma makes it possible to identify the patients at risk of intracerebral lesion and to target the indications of imaging. The purpose of the registry is to describe the use, interpretation and performance of the S100B protein in its use at bedside in emergency medicine.

NCT ID: NCT02754375 Recruiting - Depression Clinical Trials

SMTr-METAB : FDG-PET Assessment of Cerebral Metabolism in Resistant Depression Treated With rTMS

Start date: May 2016
Phase: N/A
Study type: Interventional

Biological markers of depressive states have been studied, but their usefulness to predict the therapeutic response is unknown. This issue is major in all depressive states which have not remitted after several lines of treatment. rTMS (repetitive transcranial magnetic stimulation) is a non-pharmacological alternative in the treatment of depression, but its effects on cerebral functioning are not known in episodes which have resist to conventional treatments. The investigators will include 50 depressive patients who have failed to respond to two successive antidepressant medication, and propose them a treatment with low frequency rTMS during 3 to 6 weeks. Cerebral functional imaging with 18FDG-PET (positon emission tomography) with be assessed at the beginning and at the end of rTMS acute treatment, in order to measure induced metabolic changes and their correlation with clinical states. Patients who have responded to rTMS acute treatment may continue this therapeutic for six months, and the investigators will assess if efficacy maintenance is related with cerebral metabolic variations

NCT ID: NCT02744989 Recruiting - Schizophrenia Clinical Trials

STIM'ZO : Examining tDCS as an add-on Treatment for Persistent Symptoms in Schizophrenia

Start date: May 30, 2016
Phase: N/A
Study type: Interventional

This project aims to provide the proof of concept for transcranial direct-current stimulation (tDCS) in the treatment of resistant/persistent Schizophrenia symptoms. The purpose is to investigate the effect of tDCS on symptoms in schizophrenic patients demonstrating a partial response to a first frequently prescribed antipsychotic medication. An early optimization of the therapeutic strategy must constitute an important factor for prognosis. Hypothesize is that tDCS should alleviate symptoms in patients depending on the clinical characteristics. In this study, stimulation is an add-on treatment to antipsychotic medication, and will be used in a broad variety of patients, i.e. in patients with varied durations of illness, various symptoms profiles, and various levels of treatment response. This in turn will allow the determination of the extent to which results can be generalized to varied patient populations, as well as the extent to which various therapeutic targets (e.g. different symptom dimensions, cognitive performance and brain connectivity) may be improved with tDCS. Despite interesting preliminary results, our team is unable to describe optimal non-invasive brain stimulation (NIBS) response markers. This study is a randomized, double blind, controlled, French multicenter study (11 centers). The investigators plan to include 138 patients with persistent symptoms in schizophrenia. Sixty-nine subjects will receive active tDCS and 69 subjects will receive sham tDCS (placebo). Hypothesize is a lasting effect of active tDCS on the schizophrenic symptoms as measured by the number of responders, defined as a decrease of at least 25% of symptoms as measured by a standardized clinical scale score (PANSS) between baseline and after the 10-session tDCS regimen. Furthermore, the participants believe that an in depth understanding of the cortical effects of tDCS could constitute an important step towards improving the technique and developing treatment response markers. An analysis of the effects on cortical activity and plasticity markers could be an interesting approach.

NCT ID: NCT02689622 Active, not recruiting - Clinical trials for Myelodysplastic Syndromes

PREDICTive FactOR of Overall Survival Among Geriatric Assessment Tools and Disease Related Factors in Elderly Patients With High Risk Myelodysplastic Syndromes.

Start date: April 20, 2016
Phase: N/A
Study type: Interventional

No prospective study was conducted in elderly patients with cancer to assess the relative value of disease-related and patient-related prognosis factors. Patient-related prognostic factors have been highlighted in elderly patients with cancer resulting in the necessity of a geriatric assessment. The impact on overall survival of all of these factors was recognized in elderly people with cancer but remains unknown in High Risk Myelodysplastic Syndromes (HR-MDS). Therefore this information could be crucial to better select geriatric assessment domains relevant for the prediction and to recommend simplified tool after stratification of geriatric assessment domains thanks to their predictive value. The main hypothesis is that patient-related factors will have a better capacity to predict survival and treatment tolerance than disease-related factors in HR-MDS aged 75 and over and that the predictive value will be different among assessment tools which allows a selection of reduced number of tools for clinical use. To best knowledge estimation of predictive value of geriatric assessment tools remains unknown and explains why no standardization of practice exists. In testing all tools at the same cohort of patients allows to compare different tools and to define minimal and optimal geriatric assessment for HR-MDS. To determine the best strategy of geriatric assessment will allow in a second time to measure the impact of the use of this geriatric standardized evaluation by comparing patients'care and prognosis according to the use or not by the doctors of the new scores. Research outcomes are various medical, economic and ethic. Medical because decision-making will be improved with simplified geriatric assessment; economic because a better knowledge of geriatric assessment will improve treatment toxicity prevention and decrease treatment costs. Ethic will be associated with this project because a better knowledge of geriatric assessment tools to predict survival and tolerance treatment could improve the choice of best supportive care if prognosis markers are not favorable to active therapy. This project could induce important modification of practice in this area to an improved personalized treatment and simplification of geriatric assessment allowing a large diffusion in hospitals and clinics.

NCT ID: NCT02547493 Recruiting - Clinical trials for Rheumatoid Arthritis

Vaccination Against Pneumococcal in Naïve Abatacept Rheumatoid Arthritis Patients

Start date: March 3, 2016
Phase: N/A
Study type: Interventional

Is pneumococcal conjugate vaccine (which induces a T-dependent humoral response) more efficient than pneumococcal polysaccharide vaccine (which induces a T-independent humoral response) in RA patients treated with abatacept, biotherapy targeting T-cells?

NCT ID: NCT02469753 Recruiting - Clinical trials for Ankylosing Spondylitis

Interest of Continuous Non-Steroidal Anti-Inflammatory Drug Treatment in Ankylosing Spondylitis Patients Treated by Anti-TNF Therapy in the Prevention of Radiographic Outcomes

Start date: October 23, 2015
Phase: Phase 3
Study type: Interventional

Ankylosing spondylitis (AS) is a frequent chronic inflammatory rheumatic disease that affects the axial skeleton, starting in the sacroiliac joints and spreading to the spine in most patients. Non-steroidal anti-inflammatory drugs (NSAIDs) are the primary treatment for AS. Even if the use of anti-TNF agents has demonstrated good clinical efficacy in controlling inflammation, in contrast to other conditions such as rheumatoid arthritis and psoriatic arthritis, anti-TNF treatment has failed to demonstrate any benefit on the structural progression of AS, some data even suggesting that it may accelerate the formation of syndesmophytes that seems to be an independent process of TNF. Conversely, NSAIDs inhibit ossification phenomena independently of their anti-inflammatory properties, owing to a specific action on bone formation via prostaglandin inhibition. Several features suggest that a continuous NSAID therapy is needed, in addition to anti-TNF treatment, to prevent syndesmophyte formation in AS patients.
