NCT ID: NCT03680963 Not yet recruiting - Clinical trials for Acute Circulatory Failure

Early Versus Differed Arterial Catheterization in Critically Ill Patients With Acute Circulatory Failure:

Start date: October 31, 2018
Phase: N/A
Study type: Interventional

The objective of the present research is a combination of a one-sided test of non-inferiority and a one-sided test of superiority. A stepped approach will be used to evaluate these hypotheses: 1. a less invasive intervention (i.e., no indwelling arterial catheter insertion until felt absolutely needed, according to consensual and predefined safety criteria) is non inferior to usual care (i.e., systematic indwelling arterial catheter insertion in the early hours of shock) in terms of mortality at day 28 (non-inferiority margin of 5%). 2. a less invasive intervention is not only non-inferior but also superior to usual care in terms of mortality. Multi-centre, pragmatic, randomised, controlled, open, two-parallel group, non-inferiority clinical trial.

NCT ID: NCT03680937 Not yet recruiting - Cancer Clinical Trials

Methods for Fertility Preservation: Impact of Vitrification on in Vitro Matured Oocytes

Start date: September 20, 2018
Study type: Observational

During the last decades, there was an improvement of the cancer treatments of the woman and the teenagers. Therefore higher survival rate is described. However, cancer treatments can alter the reproduction functions and reduce considerably the window of the fertility to the adulthood. Therefore, it is recommended to proceed to a fertility preservation by oocytes vitrification when it is possible. The vitrification is a freezing technique allowing high survival rate and similar results by assisted reproductive technologies compared with the use of fresh oocytes. An innovative method of automated vitrification was recently developed. The usual protocol consist to vitrify mature oocytes. However, this strategy cannot be used for hormone -sensitive cancer or when ovarian stimulation is not possible. In these situations, immature oocytes can be collected. It is also necessary to realize an in vitro maturation step for a use by assisted reproductive technology. According to the recent data of the literature, it remains unclear whether the vitrification of ovocytes must be performed before or after in vitro maturation (IVM). Therefore the aim of this study is to study the impact on structure and functions of ovocytes when vitrification is performed before or after IVM. The vitrification will be performed by a semi-automatic method which is an innovative method.

NCT ID: NCT03680794 Recruiting - Clinical trials for Diabetic Retinopathy

Soluble Cluster of Differentiation 160 (sCD160) in Sera and Intra-ocular Fluids: Association With Ischaemic Retinopathies

Start date: May 2, 2018
Phase: N/A
Study type: Interventional

CD160 represents a new angiogenic factor as its specific engagement by an agonist monoclonal antibody directed against human CD160 reduced angiogenesis of endothelial cells with a distinct mechanism from current angiogenic therapies that target the VEGF/VEGF-R pathway. A soluble form of CD160, sCD160, has been found to be highly expressed in the vitreous and the sera of patients with severe diabetic retinopathies, and can now be dosed with help of an ELISA test. The investigators aim to evaluate the association between ischaemic retinopathies (patients with or without) and sCD160 concentrations in the vitreous, the aqueous humour and the serum.

NCT ID: NCT03680651 Recruiting - Prenatal Disorder Clinical Trials

Frequency and Type of Genetic Abnormalities Found in Antenatal Corpus Callosum Malformation

Start date: June 18, 2018
Study type: Observational

Corpus callosum malformation (CCM) is the most frequently detected cerebral defect diagnosed in the prenatal setting. The most common CCM is corpus callosum agenesis (CCA) which is found in 2 to 3% of patients presenting with intellectual disability. When CCM is diagnosed, the risk of chromosomal disorder is estimated to be 16%, be it aneuploidy such as trisomy 18, trisomy 13 or mosaic trisomy 8, or a chromosome structure anomaly, copy number variation or more complex rearrangement In France, since 2013 oligoarray-based comparative genomic hybridization (aCGH) analysis is performed in the prenatal period for most malformations after approval by a multidisciplinary prenatal diagnosis ethics committee (Centre Pluridisciplinaire de Diagnostic Prénatal, CPDPN) . However, to date only a few studies have been published which report recurrent Copy Number Variations (CNV) associated with CCM and estimate the risk for a chromosomal disorder, thus making counseling difficult in this context of prenatal diagnosis.

NCT ID: NCT03680430 Not yet recruiting - Clinical trials for Sarcoma, Soft Tissue

Evaluation of Adaptive Radiation Therapy in Pre-operative or Exclusive Radiation Therapy for Limb Soft Tissues Sarcomas

Start date: June 20, 2019
Phase: N/A
Study type: Interventional

Soft tissue sarcomas (STS) is generally treated by surgery, followed or preceded by radiotherapy and chemotherapy. Preoperative irradiation has been shown to be effective in a randomized trial, and is often indicated in locally advanced Soft tissue sarcomas of the limbs, in order to reach R0 resection, or in case of rapid tumor growth despite first chemotherapy. For inoperable sarcomas, radiotherapy is an efficient palliative treatment, increasing local control. Adaptive radiotherapy is defined as the set of procedures leading to the modification of a treatment plan based on the individual variations observed during irradiation. The place of this technique is increasing since the development of image-guided-radiotherapy allowing the visualization of daily variations in position, shape or volume of the tumor and organs at risk. Its implementation in current practice however remains limited because of the cumbersome processes involved (new delineation, new dose calculation, or even re-optimization) and resources to commit, especially in human time. Irradiation of soft tissue sarcomas always begins with a planning CT scan, where the target-volumes and organ at risk are delineated, and dosimetric calculations are performed prior to radiotherapy initiation. During the radiotherapy, the variations leading to a mismatch between the planned dose and the dose delivered are multiple. These may be due to positioning errors or morphological changes in the patient (weight loss), or in the tumor or organs at risk (modifications in shape, size or position). The volume of soft tissue sarcomas changes also during radiotherapy (response, progression or pseudo- progression of the tumor). However, to date, few data are available in the literature both on the volume variation of soft tissue sarcomas during preoperative radiotherapy, and on the interest of adaptive radiotherapy in the management of these tumors. It is therefore necessary to evaluate whether modifications of growth or macroscopic tumor volume are observed during the treatment, and to evaluate dosimetric impact on the target volume coverage that could impact the results of the treatment. This a prospective multicentric phase II trial conducted to evaluate the interest of adaptive radiotherapy in the preoperative or exclusive management of limb sarcomas Patients will be treated by preoperative or definitive radiotherapy for a limb soft tissue sarcomas, using an intensity-modulated conformal irradiation (with a static or dynamic technic), over 5 to 7 consecutive weeks. The total dose delivered will be of 50 Gray (preoperative radiation therapy), or 60 to 70 Gray (exclusive radiation therapy). The delineation of growth or macroscopic tumor volume,clinical target volume, and planning target volume, as well as healthy surrounding tissues will be carried out in each of the centers, and under the responsibility of the radiotherapist, on The simulation CT-scan, used for dosimetry, and 3 CT scan performed on day 1 of radiotherapy (d1), at a dose of 30Gy (d30Gy) and 50Gy (d50GY). The dosimetric re-planning according to the variations of the volume of the planning target volume will be done in case of significant variation of the target volume according to de definition mentionned in the main and secondary objectives. Main objective: The aim of this study is to evaluate the interest of adaptive radiotherapy in the preoperative or exclusive management of limb sarcomas. This is the first prospective trial focused on the evaluation of the volume variation of soft tissue sarcomas during preoperative radiotherapy, and also on the interest of adaptive radiotherapy in the management of these tumors, whereas indications of preoperative and/or exclusive radiation therapy are very frequent.

NCT ID: NCT03679546 Not yet recruiting - Ulcerative Colitis Clinical Trials

EFFICACI : EFFicacy of Intravenous Infliximab Versus Vedolizumab After Failure of subCutaneous Anti-TNF in Patients With UlCerative Colitis

Start date: December 1, 2018
Phase: Phase 4
Study type: Interventional

Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) that results from immune dysregulation. Arguably, the development of Tumor Necrosis Factor (TNF) antagonists (including infliximab, adalimumab and golimumab) revolutionized the management of immune-mediated chronic diseases in the past two decades. However, about one third of patients will not respond to a first anti-TNF treatment and 10% to 30% will loose response to anti-TNF during the follow-up. Historically, a switch between anti-TNF was performed to recapture remission and response to anti-TNF. Recently, a new biologic therapy blocking another target has been approved and is now reimbursed during ulcerative colitis, namely vedolizumab. Vedolizumab is an anti-integrin agent avoiding the recruitment of lymphocytes specifically in inflamed gut tissue. Emerging data suggest that a switch of therapeutic class (meaning a change of biologic target with Non-TNF-targeted biologic) in case of clinical failure or insufficient response to anti-TNF may be the best choice. This idea of a switch out of the anti-TNF class is also supported by data on drug monitoring that may help physician decision making in case of loss of response. However, no trial is currently available and ongoing to assess the best therapeutic strategy. The aim of the proposed study is to assess the best biological based strategy in patient losing response to a first subcutaneous anti-TNF (golimumab and/or adalimumab).
