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.
Evaluation of the add-on effect on endothelial dysfunction of treatment of periodontitis in patients with chronic periodontitis and severe obstructive sleep apnea treated by CPAP. Patients with and without chronic periodontitis will be treated by CPAP for 20 weeks. At V2 (10 weeks), endothelial dysfunction will be assessed by the Reactive Hyperemia- Peripheral Artery Tone index. The endothelial dysfunction of the patients will be also assessed at V3 (20 weeks) after periodontitis treatment for the group of patients with chronic periodontitis.
From a cellular perspective, breast cancers appear to develop hierarchically from a small contingent of cancer stem cells (CSCs). The presence of CSCs in tumor tissue is associated with an increased risk of recurrence and metastasis, as well as a worse prognosis. Thus, these CSCs exhibit resistance to conventional anti-tumor treatments such as radiotherapy and chemotherapy. Moreover, these treatments would favor the emergence of these CSCs and the reprogramming of non-CSCs in CSCs. It has been demonstrated in neoadjuvant that the proportion of CSCs before any treatment is correlated with chemoresistance and that a resurgence of CSCs after chemotherapy is correlated with a poor prognosis. However, the mechanisms involved in the emergence of CSCs by reprogramming of non-CSCs are not yet known. The Oscar Lambret Center proposes a monocentric prospective interventional study based on the cellular and molecular analysis of the tumor, serum and circulating cells, before, during and at the end of the treatment for each patient receiving a neoadjuvant chemotherapy for breast cancer. The identification of the mechanisms contributing to the enrichment of CSCs resistant to chemotherapy could lead to therapeutic solutions.
The primary objective of this study is to evaluate the safety of ENTO with VCR in participants with relapsed or refractory B-cell NHL.
Treatment of periodontal diseases is influenced by several risk factors. Psychological stress is considered as one of them. Aim of this study is to assess if stress influences results of non surgical periodontal treatment in severe chronic forms of periodontitis.
The drastic reduction of nutritional intake in anorexia nervosa(AN) alters many hormonal factors that regulate the activity of bone cells. This alteration of bone remodeling is characterized by increased bone resorption and decreased bone formation, leading to a marked reduction of bone mineral density, osteoporosis and an increased risk of fracture. To date, there is a paucity of studies and no consensus on the management of bone loss in patients with AN. The few previous studies were performed with small samples and using short follow-up periods. Denosumab is a fully human monoclonal antibody that binds with high specificity to human RANKL (6, 7), thereby reducing the number and activity of osteoclasts and therefore decreasing bone resorption that was found increased in patients AN. Denosumab may transiently protect bone whilst psychonutritional management will induce a weight restoration
Pre-clinical and clinical evaluations show that PRTX- 100 has biological activity that may lead to improved platelet levels where these are decreased due to immunological pathologies and that PRTX-100 has an acceptable safety profile. In vivo treatment with PRTX-100 has been shown to raise platelet counts in a mouse model of immune thrombocytopenia (ITP). The primary objective of the study is to assess the efficacy of PRTX-100 in terms of platelet response in patients with chronic/persistent ITP.
Arthrodesis shoulder blade/humerus under arthroscopy. Implementation of an external fixative spray at the proximal level in the thorn of the scapula and distal in the diaphysis humerus.
Normal values for muscle strength using hand held dynamometer and muscle mass using echography are largely unknown. The objective of the present study is to establish normal values of these measurements in population living in France.
The aim of the study is to assess prospectively the impact of radiosurgery on the quality of life in patients with brain metastases.
The purpose of this study is to evaluate whether the use of bivalirudin will reduce extent of the damage done to the heart muscle in participants who suffered a heart attack, compared to the comparator treatment (heparin).
