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.
After curative surgical resection, detection of metastatic lymph node remains the main prognostic validated criteria on which is based the decision of adjuvant therapy. To date, none of the molecular alterations, identified as potentially predictive factor, are used in routine for therapeutic decision. The circulating markers, either in the form of free circulating DNA or in the form of circulating tumoral cells seems important potential candidates. To investigators knowledge, only one study estimated with several interesting results the prognostic interest of a coupled detection of the free circulating mutant DNA (gene KRAS) and by the hypermethylation of the p16 gene. Definitive conclusions remain however difficult to achieve because of the small number of patient included (n=58) and the fact that this study included different stages. For colorectal cancer a Chinese team presented a series of results suggesting that the presence of CTC during the postoperative course is a factor significantly related to the risk of recurrence. In multivariate analysis integrating the lymph node status and the vascular invasion, the presence of CTC appeared as an independent factor for recurrence with a hazard ratio of 29.5. The aim of the present study is to compare the prognostic value of two circulating tumoral markers KRAS point mutations and RASSF2A methylation (free tumoral DNA) and Circulating tumoral cells (CTC). The primary objective is to compare sensibility and specificity of two circulating markers (free tumoral DNA and tumoral cells) on 2 years disease free survival rate. Secondary objective is to confirm the prognostic value of circulating free tumoral DNA and circulating tumoral cells in localised colorectal cancer.
Investigating the interrelation of stroke and sleep-disordered breathing (SDB) is of major importance. First because of the high occurrence rate of stroke and the fact that it is a frequent cause of long-term disability in adulthood. Second because SDB (obstructive, central and mixed forms) affects more than 50% of stroke survivors and has a detrimental effect on clinical stroke outcome. Third, spontaneous and learning-dependent sleep-associated neuroplasticity may be affected by SDB following stroke worsening stroke rehabilitation. Therefore, it is crucial to investigate whether early treatment of SDB with Adaptive Servo-Ventilation (ASV), the treatment device of choice to treat obstructive, central and mixed forms of SDB, has a beneficial effect on the evolution of the lesion volume and on clinical stroke outcome. To this end, the investigators recruit and prospectively follow 3 groups of patients with ischemic stroke over 1 year. During the first night after hospital admission due to acute stroke, nocturnal breathing is assessed by means of a respiratory polygraphy. Patients with significant sleep disordered breathing, defined as an Apnea-Hypopnea-Index (AHI) > 20/h, are randomized to ASV treatment or no treatment (sSDB ASV+ or sSDB ASV-). ASV treatment starts the second night following hospital admission and ends 90 days later. Stroke patients without SDB (AHI < 5 / h) serve as a control group (no SDB) to observe the evolution of the lesion volume and stroke outcome without the additional burden of SDB. Lesion volume one day after hospital admission due to acute stroke (after potential lysis therapy) measured by Diffusion Weighted Imaging will be subtracted from lesion volume measured by T2-weighted volumetry assessed 90(+/-7) days following stroke and compared between patients with and without ASV treatment (sSDB ASV+ and sSDB ASV-) as well as patients without SDB (no SDB). Short- and long-term clinical stroke outcomes are assessed by clinical scales and questionnaires 4 to 7 days, 3 months and 1 year following stroke. Cognitive outcome is assessed during hospitalization (within the first week following stroke) and after the treatment period of 90 days by neuropsychological tests assessing attention and memory. In addition, baseline assessment of physiological parameters such as blood pressure and endothelial function/arterial stiffness are assessed during the first weeks following stroke and at the end of the treatment period, i.e. approximately 90 days following stroke.
The purpose of this study is to determine whether the combination therapy of CC-486 (oral azacitidine) and pembrolizumab provides improved patient outcomes compared to pembrolizumab alone in patients with previously treated locally advanced or metastatic non-small cell lung cancer.
This is an open label, multi-drug, biomarker-directed, multi-centre, multi-arm, Phase 1b study in patients with muscle invasive bladder cancer (MIBC) (urothelial) who have progressed on prior treatment. This study is modular in design, allowing evaluation of the safety, tolerability, pharmacokinetics and anti-tumour activity of multiple agents as monotherapy and as combinations of different novel anti-cancer agents. The study will consist of a number of study modules (sub-studies), each evaluating the safety and tolerability of a specific agent or combination.
The purpose of this study is to evaluate if the addition of daratumumab to Bortezomib, Thalidomide and Dexamethasone will increase the stringent complete response rate after consolidation therapy and increase the progression free survival after daratumumab maintenance therapy in transplant eligible participants with previously untreated Multiple Myeloma.
The FANTOM II trial is intended to assess safety and performance of the Fantom Bioresorbable Coronary Scaffold in native coronary arteries.
Medtronic is sponsoring the Micra Registry to further confirm safety and effectiveness of the Micra Transcatheter Pacing System (Micra system) when used as intended, in "real-world" clinical practice, following commercial release. The Micra Registry is conducted within Medtronic's Product Surveillance Registry.
The purpose of this study is to determine if apalutamide plus gonadotropin releasing hormone (GnRH) agonist in participants with high-risk, localized or locally advanced prostate cancer receiving primary radiation therapy (RT) results in an improvement of metastasis-free survival based on conventional or prostate specific membrane antigen-positron emission tomography (PSMA-PET) imaging evaluated by blinded independent central review (BICR).
Total hip arthroplasty (THA) is one of the most effective medical procedures. Except for the few early complications (acute infections and dislocations), the patient made a PTH can be assured of a significant improvement in its function and its short-term quality of life. However, clinical studies and records have shown that the lifetime of these implants was limited. The main cause of failure is the "aseptic loosening" influenced by many factors, foremost of which is due to periprosthetic osteolysis debris. This is a major concern for orthopedic surgeons loosening leads, in most cases, the recovery, the importance of osteolysis is a major cause of difficulties and poorer results. The main objective of the study is to compare, 2 years after the intervention, the penetration of the femoral head in the polyethylene and X3 in the acetabulum in N2VAC® conventional polyethylene.
The total hip replacement, with over 120,000 cases per year in France, provides short term, excellent functional results and a significant improvement in quality of life, in almost all cases. However, the observation has shown that the lifetime of the implants is limited due to aseptic loosening. One of the factors associated with these failures is a peri-prosthetic osteolysis wherein the polyethylene wear debris (PE) have been implicated. Several solutions have been proposed: change the friction torque (hard-hard pairs using ceramic or metal on the two components of the couple) or improving quality polyethylene. Improving the resistance of polyethylene wear is the primary objective evaluated in this study.
