NCT03343834
Scientific context Epstein-Barr virus has a causal role in the pathogenesis of multiple distinct lymphomas. Post-transplant lymphoproliferative diseases (PTLD) are the most frequent EBV-induced proliferations. PTLD after allogeneic stem cell transplantation has an incidence lower than 5% but may increase up to 10-20% in patients with established risk factors. EBV-DNAemia is predictive of EBV-PTLD and is routinely performed using qPCR on whole blood. Preemptive therapeutic strategies with anti-CD20 antibody are used when patients are above a defined EBV-DNAemia threshold. This approach remains limited since it does not discriminate between an EBV-induced lymphoproliferation (latent cycle) and/or a replicating virus (replicative cycle). Epigenetic modifications plays a central role in regulating the switch from latent to lytic gene expression. Specific DNA modifications can be regarded as molecular signatures for EBV genomes associated with the status of the viral infection (latent vs lytic). Accordingly, these signatures may be envisioned as a potent tool to characterize the state of the viral infection in vivo. Description of the project Our primary objective is to estimate the respective percentages of EBV-lytic and EBV-latent genomes (proliferating cells) in patients presenting with a high EBV-DNAemia after allogeneic stem cell transplantation HSCT by analysing the epigenetic modifications of EBV genome on specific sites. Our secondary objectives are i) to determine risk factors associated with each "latent versus lytic EBV" profiles and ii) to correlate the "latent versus lytic EBV" profiles with response to rituximab infusion and patient outcomes. For this purpose, a retrospective study (n=80) and a prospective study (estimation n=58) will be established. The different steps of this project are: 1. To study epigenetic modifications. The laboratory is developing a new approach to distinguish between latent and lytic genomes. 2. To realize quantitative analysis by RT-PCR of different EBV transcripts specific of the latent or of the lytic phase of the virus This method will be applied on RNA extracted from patient blood samples with elevated EBV viral load, under condition preserving RNA integrity. The results will be validated on a prospective cohort of HSCT patients (n=58) (Saint-Antoine Hospital and La Pitié-Salpêtrière Hospital). 3. To perform quantitative analysis of EBV genomes in plasma, saliva and total blood samples by current routine procedures In addition to total blood samples, plasma and saliva will be collected since free viral particles are known to accumulate in these biological fluids upon EBV reactivation. These samples will be treated by normalized procedures that are routinely used in the medical virology laboratory to quantify EBV in human samples. Expected results By establishing a simple method for studying epigenetic modifications of EBV genomes, we expect to understand the significance of high EBV viral load and the pathophysiology of post-HSCT PTLD. We aim to distinguish between the latent / lytic profiles of HSCT patients and to correlate their respective risks for developing PTLD. Establishing the epigenetic EBV profile in the post-HSCT setting when facing increase viral load and PTLD will improve our understanding of the biological mechanisms determining EBV-status in post-HSCT. This should improve major medical and economical issues. These results could have a major therapeutic
NCT05090956
Since January 2010, a new magnetic resonance imaging scanner (Philips 3T, Achieva) is installed on the Baudot Building in Toulouse hospital. This tool, is completely dedicated to the research. It was installed with sequences RMN supplied by the manufacturer. Imagers also contain an instrumentation susceptible to evolution and/or to adjustment (antennas radio frequency, sheath of gradients, elements of physiological monitoring (for example control of the breath), regulation of the homogeneity of the magnetic field). This MRI scanner and this instrumentation are used for anatomical examinations or for paradigms of cognitiveresearch (for example of detection of intellectual activations following simple stimuli of fingers movement, visual tasks, or of mental processes). The developpement of this equipment is going to favor the emergence of numerous projects and new themes, up to there adressed by other techniques (psychophysics, EEG). To obtain good quality signals and know the practical limits of this imager, it is thus necessary that the researchers doctors, physicists and engineers, can finalize on volunteers' significant number, all the sequences RMN necessary for the use of these tools for the research. These developments are going to get organized around four main axes: 1 the control of the geometrical distortions (generated by the introduction of an object within the magnetic field) 2 Optimization of the parameters of sequences to improve the contrast and the spatial resolution of the obtained images 3 the development of new sequences 4 the feasibility study of the protocols of functional MRI

NCT02664597
Background : About 25% of adnexal masses remain indeterminate after transvaginal ultrasonography, as evidenced by the published literature. According to a multicenter study conducted in France by Huchon et al., surgery is mainly indicated based on tumor size and ultrasonographic appearances and a high rate of benignity is finally found at pathology (83.3%). MRI is the most accurate second-line imaging technique for characterizing adnexal masses with an accuracy\>95%. However, among physicians, a debate exists on the relevance of MR imaging to characterize adnexal masses possibly due to the absence of standardization of the MR report. In 2013, the first MR scoring system for adnexal masses named "ADNEXMR score" was developed and found to be accurate, with an AUROC\>0.94 to distinguish benign from malignant adnexal masses. Indeed, our hypothesis is that ADNEXMR score that relays the radiologist's suspicion of malignancy to clinician has the potential aim of improving patient management, in particular by limiting the number of patients undergoing inappropriate surgery. Main objective: To compare the rate of inappropriate surgery that occurs when patients are managed according to the therapeutic strategy based on ADNEXMR score with the therapeutic strategy performed in clinical routine. Primary endpoint: The rate of inappropriate surgical intervention during the two first months after MR imaging (i.e. unnecessary diagnostic surgery for benign lesions and incomplete staging for borderline or invasive cancer). Study design: * The study is a prospective multicenter randomized diagnostic study. 606 patients will be included by 9 hospitals (17 centers). * Total duration of the study is 56 months with 32 months for patient inclusions. * At D0, following informed written consent, patients will be randomized in one of two groups (intervention group or control group). In the intervention group, patients will undergo a pelvic MR imaging (1.5T or 3T) as routinely performed, including morphological sequences (T2, T1 with and without fat suppression and T1 after dynamic gadolinium injection) and functional sequences (perfusion and diffusion-weighted sequences). Prospectively, a senior radiologist analyzes the different MR criteria to characterize adnexal masses. The reader will classify the mass using ADNEXMR SCORING system and the patient will be managed according to the score. In control group, the complex adnexal mass will be managed according to the standard strategy and treatment plan routinely used by the multidisciplinary team. Clinical, biological, ultrasonographic and/or MR data and the type of treatment will be recorded. If a surgery is required, surgical procedure will be performed within the two months after initial diagnostic imaging (as routinely recommended). At M6/M12, follow-up will be performed. If the lesion has increased or changed with suspicious criteria, surgery will be performed as routinely recommended in both groups. At M24, adnexal masses status will be recorded by clinical and imaging follow up.

NCT01635192
Probiotics have become very popular and are by WHO defined as "Live microorganisms which when administered in adequate amounts confer a health benefit on the host". For example, probiotics have been shown to contribute to improvements of abdominal discomfort and intestinal inflammation. The main hypothesis behind the present study is that probiotics influences mucosal regulatory systems, particularly the actions of the hormone Angiotensin II locally in the intestinal mucosa.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Biological therapies use different ways to stimulate the immune system and stop cancer cell from growing. Combining more than one chemotherapy drug with biological therapy may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy, isotretinoin, and interferon alfa in treating patients who have acute myelogenous leukemia.
NCT01799135
This is a pilot study. A pilot study is done with a small number of participants to see if a technique works before using it in a larger research study. This pilot study is evaluating a special kind of MRI scan of the lungs called dynamic contrast enhanced MRI (DCE-MRI). DCE-MRI can demonstrate how much blood flows through the tumor and lungs and tell us how active the tumor is, as well as how functional the lungs are. As part of this scan, participants will receive an intravenous (into the blood via puncture of a vein) injection of gadolinium contrast, a dye that helps us see the tumor and lung tissue more clearly. Gadolinium is approved by the FDA and is routinely used for MRI. The goal of the study is to determine whether DCE-MRI can provide images of the response of the tumor and the normal lung tissue to SBRT and to potentially hep improve treatment-planning methods for patients treated with SBRT in the future. We will also study how the final DCE-MRI scan compares with another form of imaging, called 4-dimensional computed tomography (4D-CT), that looks at the breathing capacity of the lungs. Although we are researching the usefulness of DCE-MRI in early stage non-small cell lung cancer treated with SBRT in this study, DCE-MRI with the dye injection is not an experimental technology and is routinely used in the clinic for other indications. The 4D-CT scan is also not experimental and is used for radiation planning and imaging of the lungs. The SBRT you will receive will be standard treatment and will not be affected by your participation in this study or by these DCE-MRI scans. That means that the findings on the scan will not be used to alter your planned treatment in any way. Additionally, participants will undergo the routine work-up prior to SBRT and surveillance studies after treatment is complete.

NCT02298166
The main trial is a double-blinded, placebo-controlled, randomized, phase III, multi-center trial in adult patients with relapsed or refractory AML harboring an activating FLT3 mutation as defined in the inclusion /exclusion criteria. An initial open label dose-finding run-in phase I of the study will be performed administering the study drug crenolanib with salvage chemotherapy consisting of mitoxantrone and cytarabine (MC) in 18 patients according to the experimental arm of the study. After completion of this dose-finding run-in phase I, toxicity and response data will be provided to the external Data and Safety Monitoring Board (DSMB) and the Trial Committee by the Coordinating Investigator. The Trial Committee will decide on the basis of these data and the recommendation of the DSMB on dose modification and the further conduct of the study with regard to the double-blinded, placebo-controlled, randomized phase of the study. The double-blinded, placebo-controlled randomized portion will start after the completion of the dose-finding run-in phase I and positive opinion of the Trial Committee. Crenolanib starts on day 7 of MC and is given continuously until 48 hours prior to the next chemotherapy; if receiving allogeneic HCT, crenolanib is held 48 hours prior to conditioning and restarts no sooner than 30 days and not later than day 100 after transplant. Sample size randomized phase: 276 patients Primary objective: To evaluate the impact of crenolanib given in combination with salvage chemotherapy and consolidation including allogeneic hematopoietic cell transplantation and ongoing single agent maintenance therapy with crenolanib on event-free (EFS) and overall survival (OS) in adult patients with relapsed or refractory AML harboring FLT3 activating mutations.
NCT02853318
This phase II trial studies the combination of pembrolizumab, bevacizumab, and low dose oral cyclophosphamide in treating patients with recurrent ovarian, fallopian tube, or primary peritoneal cancer. Monoclonal antibodies, such as pembrolizumab and bevacizumab, may block tumor growth in different ways such as boosting your own immune system to find, recognize and kill tumor cells as well as by blocking the growth of new blood vessels necessary for tumor growth and nutrition. Drugs used in chemotherapy, such as low dose oral cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, as well as by further enhancing your own body's immune response against cancer cells. As these three drugs have all been shown to improve the immune response against cancer cells giving pembrolizumab, bevacizumab, and cyclophosphamide together may work better in treating patients with recurrent ovarian, fallopian tube, or primary peritoneal cancer.
