Filter by:Myelodysplastic syndromes (MDS) are a pre-leukemic condition with an extremely poor prognosis despite current treatments that justify new therapeutic approaches. Various studies have described the potential involvement of both immune compartment and cellular metabolism in the pathophysiology of MDS. The aim of this study is to determine the specific immune and metabolic profiles of the different classes of MDS and to identify predictive markers of progression/survival/response to therapy.
Rationale: Health related Quality of life (HRQoL) is impaired in patients with Turner and Klinefelter syndrome (TS and KS). It is unknown what the optimal endocrine treatment target values are that maximize HRQoL in patients with these syndromes. Therefore the relation between HRQoL and biochemical parameters will be studied in large cohorts of patients with TS and KS. This information will give essential insight that will help to improve endocrine treatment and HRQoL in these patients. Research objectives: To explore the relationship between biochemical parameters and HRQoL in patients with TS and KS. Hypothesis: Biochemical parameters are related to HRQoL in patients with TS and KS. Study design: Cross-sectional, observational, multicentre study Study population: Patients with KS or TS, 18 years or older Methods and procedures: To measure fatigue the Checklist Individual Strength (CIS-20) will be used, for QoL the 5-level EQ-5D (EQ-5D-L5) will be used and for stress the Perceived Stress Scale (PSS) and hair cortisol levels. For patients with KS the anxiety scale from the Liebowitz social anxiety scale (LSAS) will be used to measure social anxiety. To measure the long-term exposure to testosterone in KS patients, testosterone concentrations in hair will be measured. For patients with KS, all questions from the questionnaires will be discussed orally during a visit to the outpatients clinic. One extra tube of blood and a strand of hair will be collected during routine blood withdrawal. All other variables are already part of the standard patient care and are available in patient records. For patients with TS all information including the questionnaires and laboratory values is already available and will be collected from clinical records. Main study parameters/endpoints: The relationship between different hormonal parameters and HRQoL as measured by questionnaires. The main hormonal parameter that will be investigated in KS is testosterone in hair. For patients with Turner syndrome, free thyroxine (FT4), thyroid stimulating hormone (TSH) and liver enzymes, which have already been collected, will be investigated. The relationships between the EQ-5D-L5 score and testosterone in hair (in patients with KS) and thyroid hormone status (in patients with TS) are the primary outcomes.
This phase II trial studies the effect of adding pomalidomide to usual chemotherapy treatment (daunorubicin and cytarabine liposome) in treating patients with newly diagnosed acute leukemia with myelodysplastic syndrome-related changes. Pomalidomide may stop the growth of blood vessels, stimulate the immune system, and kill cancer cells. Chemotherapy drugs, such as daunorubicin and cytarabine liposome, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding pomalidomide to chemotherapy treatment with daunorubicin and cytarabine liposome may be effective in improving some treatment outcomes in patients with newly diagnosed acute leukemia with myelodysplastic syndrome-related changes.
This study is a prospective, single-arm study conducted under a common implant and follow-up protocol. The objective will be to follow fifty-seven (57) adolescents and young adults (10-21 years of age), with Down syndrome, moderate to severe sleep apnea, and post-adenotonsillectomy, for 12 months after undergoing implant of the Inspire Upper Airway Stimulation (UAS) System. The study is being conducted in order to evaluate objective change in cognition and expressive language after implant and therapy with the Inspire UAS System.
This study is a multi-institution, open-label, Phase 1b/2 clinical trial evaluating the toxicity and efficacy of canakinumab in combination with darbepoetin alfa in patients with lower-risk MDS who have failed prior treatment with an Erythropoietin Stimulating Agent (ESA)
This study compares the efficacy of Tamibarotene in combination with azacitidine to azacitidine in combination with placebo in participants who are Retinoic Acid Receptor Alpha (RARA) positive, and newly diagnosed with higher-risk myelodysplastic syndrome (HR-MDS), and who have not received treatment for this diagnosis. The primary goal of the study is to compare the complete remission rate between the two treatment arms.
This study is designed to evaluate the efficacy and safety of eltrombopag monotherapy in Japanese adult patients with platelet transfusion-dependent lower-risk Myelodysplastic syndromes (LR-MDS).
Colorectal cancer (CRC) is the second cause of cancer-related death in western countries. CRC prevention and screening are major public health issues. Better knowledge of colorectal carcinogenesis could lead to better prevention. Gut microbiota (GM) is a complex community of bacteria, fungi, protozoa, viruses and bacteriophages which live in a symbiotic and epigenetic relationship with the host. GM can promote either digestive health or CRC through inflammatory and proliferative effects. Lynch syndrome (LS) is the most common familial CRC syndrome with a lifetime CRC risk of 52% in women and 69% in men. The risk of CRC depends upon type of altered mismatch-repair gene and environmental factors (diet, exercise, obesity, tobacco and alcohol intake, etc.). Regular surveillance including annual or biannual colonoscopy is recommended in LS patients. Chemoprevention has the potential to represent a cost-effective intervention in these high-risk patients and could allow a delay in colonoscopy surveillance. Regular low dose aspirin use is associated with a 20 to 30% reduction in the risk of sporadic colonic adenomas and CRC. The real benefit of aspirin is still to be consolidated. AAS-Lynch trial is an ongoing prospective multicenter (n=37), double-blind, placebo-controlled, randomized clinical trial, designed to investigate whether daily aspirin, at a dose of 100 or 300 mg compared with placebo, would decrease the occurrence or recurrence of colorectal adenomas in LS patients. The primary endpoint is the number of patients with at least one adenoma detected by chromo-endoscopy 48 months after initial colon clearance. At randomization and at the end of study, stool collection, blood collection, quality of life questionnaire, validated food frequency questionnaire (SU-VI-MAX2) and physical activity questionnaire are performed. The ongoing AAS-Lynch study allow accessing to a unique fecal collection in very well characterized LS patients including a comprehensive dietary evaluation at high risk for colorectal neoplasia and planned colonoscopy surveillance during a 48 months follow-up, exposed or not exposed to chronic low dose aspirin. The expertise of the scientific consortium with state of the art microbiota analysis, the comprehensive collection of data and the prospective design of the study will allow the evaluation of the true role of gut microbiota in CRC carcinogenesis.
Background: It has been proposed that a hyperactivity of the endocannabinoids system could be involved in the cognitive deficits involved in Down Syndrome (DS). Hyperactivation of the type-1 cannabinoid (CB1) receptor by exogenous cannabinoids, such as the active principle of cannabis tetrahydrocannabinol (THC), induces several modifications of the electroencephalogram (EEG). The goal of this study is to compare those CB1-dependent EEG parameters in subjects with DS and age-matched typically developing subjects (TD, control group). These investigations can increase our knowledge of the involvement of the CB1 receptor in DS cognitive deficits and potentially identify biomarkers of target engagement of new therapies of this condition. Hypothesis: It was recently showed in pre-clinical DS models that the endocannabinoid system is hyperactivated in the brain and that human adult subjects with DS showed higher plasma concentrations of the main endocannabinoids 2-arachidonoylglycerol (2-AG) and anandamide (N-arachidonoylethanolamine, 2-AEA) as compared with those found in typically developing subjects. Alterations of neural oscillations induced by the consumption of THC preparations are well established and it is hypothesized that they would be similar to those found in subjects with DS. Objectives: To assess different neural markers using electroencephalography (EEG) in typically developing subjects and in subjects with DS in resting state and while conducting selected cognitive tasks. Methods: Non-interventional, cross-sectional, monocenter study in male and female adult subjects with DS and typically developing subjects (total n=48).
