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.
Data from cohorts, prospective studies and one randomized trial (ASCOG Z0011) support the hypothesis that omission of additional axillary dissection in case of positive sentinel node has a limited impact on overall survival and relapse free survival. However, these data are not sufficient enough to recommend, as a standard of care, to avoid axillary dissection in case of positive sentinel node. The ASCOG Z0011 trial has been closed before the end of inclusions and the predefined non inferiority margin was found to be too large (5% difference at 5 years for primary endpoint). Prospective randomized trial is then urgently mandatory before omission of axillary node dissection becomes a usual practice without a sufficient scientific level of proof. Indeed, in several reviews, the rate of omission of axillary node dissection in case of micrometastasis increased (Bilimoria) despite any strong proof has been demonstrated. The omission of axillary node dissection in case of positive sentinel node may have strong practical impacts on patients but also on medical and economical aspects: in avoiding a prolonged hospitalisation, secondary morbidities due to axillary dissection requiring secondary care and their costs, as well as costs for secondary axillary dissection (14 to 25% in case of positive sentinel node) and finally shortening surgery duration. The main investigator propose a Non Inferiority Randomized Multicenter Phase III Trial of Axillary Node Dissection Versus no Axillary Node Dissection in Case of Positive Sentinel Lymph Node in Invasive Breast Cancer
This open-label, randomized, 2-arm, multicenter, phase 3 study has the primary objective of comparing the modified progression-free survival (mPFS) obtained with brentuximab vedotin (ADCETRIS®) plus AVD (doxorubicin [Adriamycin], vinblastine, and dacarbazine; abbreviated A+AVD) versus that obtained with ABVD (doxorubicin [Adriamycin],bleomycin, vinblastine, and dacarbazine) for the frontline treatment of advanced classical Hodgkin lymphoma(HL)
The STIC CTC study is a randomized trial to evaluate the medico-economic interest of taking into account circulating tumor cells (CTC) to determine the kind of first line treatment for metastatic, hormone-receptors positive, breast cancers. In the standard arm, the kind of treatment will be decided by clinicians, taking into account the criteria usually used in this setting. In the CTC arm, the type of treatment will be decided by CTC count: hormone-therapy if <5CTC/7.5mll (CellSearch technique) or chemotherapy if =5. The main medical objective is to demonstrate the non-inferiority of the CTC-based strategy for the progression-free survival: 994 patients are needed, and will be accrued in French cancer centers. Secondary clinical objectives are to compare toxicity, quality of life and overall survival between the two arms. The medico-economic study will compare cost per progression-free life years gained of the two strategies. The financial impact of centralized (one platform) vs decentralized (several platforms) CTC testing will be evaluated.
The purpose of this study is to evaluate the safety of long-term ivacaftor treatment in subjects with cystic fibrosis (CF) from Studies 110 (NCT01614457), 111 (NCT01614470), and 113 (NCT01685801).
The main aim of this clinical trial is to find a way of giving ch14.18/CHO, in combination with subcutaneous aldesleukin (IL-2) and oral isotretinoin (13-cis-RA), to children and young people with primary refractory or relapsed neuroblastoma without intravenous morphine.
This post market clinical follow-up study is designed to confirm safety and performance of the Sidus Stem-Free Shoulder when used in hemi or total shoulder arthroplasty. The safety of the implant will be evaluated by monitoring the frequency and incidence of all kinds of adverse events. The performance will be determined by analyzing the implant survival, overall pain and functional performances (based on Constant & Murley score and ASES score), subject quality of life (EuroQol EQ5D) and radiographic parameters (e.g. radiolucencies, osteolysis, component migration) of study subjects who received the Sidus Stem-Free Shoulder. The Sidus Stem-Free Shoulder is not approved for use in the US.
A clinical research study to find out if it is safe to stop the drug nilotinib (Tasigna) in chronic myeloid leukemia (CML) patients. Patients who started treatment with imatinib (Gleevec) when they were first diagnosed with CML, then switched to nilotinib (Tasigna) for at least 2 years with the combined time on imatinib (Gleevec) and nilotinib (Tasigna) for at least 3 years and have very small amount of leukemia cells remaining after the nilotinib (Tasigna) treatment will qualify for the study.
The purpose of this study is to compare the effectiveness of spinal cord stimulation (SCS) using the Medtronic Specify® 5-6-5 multicolumn surgical lead plus optimal medical management (OMM) versus OMM alone in patients suffering from predominant low back pain due to failed back surgery syndrome (FBSS).
The purpose of this study is to determine whether mid-dilution hemodiafiltration is effective in the reduction of the crude mortality risk in patients who have been undergoing renal replacement treatment for less than 1 year. Patients will be randomized since the beginning of the study in two groups: standard HF dialysis and mid-dilution HDF.
Medical and Scientific Background: Colorectal cancers (CRC) are the leading cancers in both genders. This cancer is of prognostic severity. The prognosis of this cancer has not been significantly improved. The treatment of colonic cancer is primarily based on surgery. Adjuvant chemotherapy is proposed for metastatic cancers (stages III and IV). However nearly 30% of patients with localized cancer (stage II) will present a recurrence. Despite intense research efforts, no markers of sufficient prognostic value (independent of TNM) are available to identify this group of patients and justify intensified therapy. The natural history of cancer involves interactions between the tumor and the immune system of the host. The immune infiltration at the tumor site may be indicative of host response. We showed that the density of intratumor memory T cells (CD45RO) and cytotoxic T cells (CD8) in tumor regions (the core and the invasive margin) influenced the occurrence of early events of metastasis (tumor emboli) and was strongly associated with prognosis of patients with CRC (Pagès et al, NEJM-2005). This immune criterion was a better predictor of survival than the "gold standard" histoprognostic data of tumor invasion (T stage and N) and allowed to identify a group of patients at high risk of recurrence (*2). The availability of this immune criterion in clinical practice could improve the prognostic assessment of patients and better guide the therapeutic. A dedicated platform has been implemented in our hospital to speed up the transfer of this immune investigation into the clinic. The investigation takes into account the density of immune cell populations in tumor regions (the core and the invasive front of the tumor). This methodology has been validated for the markers CD45RO, CD3 and CD8 and leads to the creation of an immune score ("immunoscore" ranging from IO to I4). We validated the prognostic impact of the immunoscore in a retrospective series of 250 colorectal cancers. The main objective of this multicentric prospective clinical study is to assess in clinical practice the "immunoscore" and measure its prognostic value. The cohort study will include 400 patients with CRC stage I to IV (6 centers for inclusion; Paris-HEGP, Dijon, Bobigny-Avicenne, Besancon, Poitiers, Rouen). Two years of inclusion and a follow-up of 3 years for each patient will be performed (co-financing for data collection during the 4th and 5th year planned). For each patient, the pathologist of the center will send to the immunomonitoring platform of HEGP tissue sections from a paraffin block containing the tumor regions. The investigations will combine a step of immunostaining for CD3, CD8, and CD45RO (Ventana automate) markers, high-resolution scanning of the stained slides and quantification of digital images by an imaging module developed by our group from the program of Developer XD of Définiens company. The immunoscore will be calculated and the score will be correlated to the clinical data for the relapse and the survival. The secondary objective of this program is to evaluate the prognostic performance of the immune infiltrate on the biopsies performed for diagnostic purposes. This study will be conducted on patients of the cohort whose biopsies were performed in the same hospital than surgery and whose samples are available in pathology laboratories involved (representing 50% of cases). For the same patients will be conducted a genetic investigation of the tumor to assess the MSI status, the presence of a K-Ras and BRAF mutations. This investigation will be performed on tumor sections from the same tumor block selected for the immunohistochemical analyses. The sections will be processed by the Department of Biology, Hôpital Européen Georges Pompidou. The prognostic performance of the immune investigations performed on tumor sections and biopsies will be compared to that of genetic features of the tumor. Finally, a questionnaire will be sent every six months along the monitoring of the patients to obtain information concerning (i) the emergence of an immune disorder (such as allergy, autoimmunity, inflammatory process) and (ii) the psychological status of the patients. The potential impact of such parameters during the course of the disease on the prediction of the relapse and survival obtained with the immunoscore performed at the time of surgery will be evaluated. Expected results : This prospective study is an indispensable step for the clinical validation of the prognostic value of the immunoscore. The secondary objectives should help to precise the benefit of a concomitant analysis of the biopsy, the genetic features of the tumor. The questionnaire should help to identify the clinical parameters to track along the monitoring
