NCT07189325
Multiple sclerosis (MS), the main central nervous system autoimmune disorder, is the first cause of non-traumatic disability in young adults and has thus significant individual consequences with elevated public health cost. It commonly starts during the third and fourth decades. Over the last twenty years, several disease-modifying therapies with variable benefit/risk profiles have been introduced leading to dramatic changes in the prognosis of MS. First, several moderately effective therapies , with good safety profile, have allowed to decrease the frequency of relapses along with a possible, albeit limited, effect on medium- and long-term disability. More recently highly effective therapies (HET), with immunosuppressive properties, have dramatically reduced clinical and MRI disease activity and significantly improved patient's prognosis. Anti-CD20 therapies (B-cells depleting therapies, given either intravenous or subcutaneous), one of the main HET, have demonstrated higher efficacy than platform therapies in several phase 3 randomized clinical trials and their use within the very first years of the disease seems to be associated with improved long-term outcomes. Taking all of this into account, the investigators hypothesize that RRMS patients who experience a de-escalation from anti-CD20 therapies to platform therapies after 40 years will not experience disease activity accrual and disability worsening.
NCT06614725

NCT07663500
This prospective, three-arm, non-randomized quasi-experimental study aims to evaluate integrated intrapartum supportive care combined with different pushing strategies among women at 37-42 weeks of gestation who receive low-dose epidural analgesia. Participants receive integrated intrapartum supportive care combined with spontaneous pushing, integrated intrapartum supportive care combined with immediate pushing, or routine intrapartum care combined with immediate pushing. The primary outcomes are the durations of the first and second stages of labor. Secondary outcomes include mode of birth, obstetric interventions, maternal outcomes, and neonatal outcomes.
NCT01432847
Background: \- Best Vitelliform Dystrophy (Best disease), Late-Onset Retinal Degeneration (L-ORD), and Age-Related Macular Degeneration (AMD) all affect the retina, the light sensing area at the back of the eye. Doctors cannot safely obtain retinal cells to study these diseases. However, cells collected from hair follicles, skin, saliva, urine, and blood can be used for research. Researchers want to collect cells from people with Best disease, L-ORD, and AMD, and compare their cells with those of healthy volunteers. Objectives: \- To collect hair, skin, saliva, urine, and/or blood samples to study three eye diseases that affect the retina: Best disease, L-ORD, and AMD. Eligibility: * Individuals affected with ocular condition is one year of age or older. * Individuals affected with Best disease, L-ORD, or AMD is 18 years of age or older. * Unaffected individuals are seven years of age or older. Design: * The study requires one visit to the National Eye Institute. * Participants will be screened with a medical and eye disease history. They may also have an eye exam. * Participants will provide a hair sample, saliva sample, urine sample, blood sample, and/or a skin biopsy. The hair will be collected from the back of the head, and the skin will be collected from the inside of the upper arm.
NCT06159335
The goal of this clinical trial is to use new imaging methods to help in finding out whether the imaging shows that there is a tumor in people with a brain metastasis. The main question it aims to answer is whether positron emission tomography (PET) and magnetic resonance imaging (MRI) find cancerous tissue better than other types of imagining. Participants will undergo a single PET/MRI scan, followed by a separate MRI scan with a tracer. Study participation will last about 3 hours.
NCT07660614
This study will examine what happens when patients with amyotrophic lateral sclerosis (ALS) are given an investigational medication (study drug) known as LTX-002. Specifically, the researchers will be looking at safety, tolerability (if someone has any side effects from the drug), pharmacokinetics (what the body does to the study drug) and pharmacodynamics (what the study drug does to the body). The study will also investigate the effect of the drug on indicators of the severity of ALS, such as markers in blood and in the cerebrospinal fluid (the fluid that surrounds the brain and spinal cord, CSF) and on measures of the participant's ability to move, speak, and breathe.
NCT06472973
Transplantation for end-stage-liver disease (ESLD) in the context of Alcohol-Associated Liver Disease (AALD) has been increasing and represents the main indication for Liver Transplantation (LT) in the world. Alcohol Use Disorder (AUD) is considered a brain chronic disease and requires a transdisciplinary approach that includes medical treatment and behavioral interventions. In the context of LT, alcohol relapse occurs in 26 % up to 50% of LT recipients. Among Liver transplant recipients for AALD, severe alcoholic relapse (defined as more than 3 alcoholic drinks per day for women and 4/day for men) after LT leads to impaired longterm survival due to recurrent alcoholic cirrhosis (RAC), cardiovascular events and de novo cancer. Several strategies have been developed to prevent alcohol relapse. After LT, integrating an addiction team into the LT program has been advocated by the latest guidelines in Europe and the United States, in order to bring the management of alcohol-use disorder (AUD) in transplantation units, through the association of psychosocial and pharmacological interventions previously reported in AALD. However, those guidelines were based on descriptive studies, and the effect of this management needs to be confirmed through a randomized, controlled, multicenter study, involving centers that still do not include an addiction team in their LT programs. This study will therefore assess prospectively and comparatively the impact of an addiction intervention after LT on return to alcohol use rates. We hypothesize that standardized targeted addiction monitoring of Liver Transplant recipients decreases the rates of alcohol relapse two years post-liver transplantation.
NCT07369076
The purpose of this trial is to learn about the effects of NB-4746 compared with placebo in people with amyotrophic lateral sclerosis. The questions this trial aims to answer in comparing NB-4746 to placebo are: * What adverse events associated with taking NB-4746 are reported during this trial? (An adverse event is any sign or symptom that participants have during a trial. Adverse events may or may not be caused by treatments in the trial.) * How does NB-4746 move into, through, and out of the body of the participants? * What is the change in the level of neurofilament light (NfL) in the participants' blood? (NfL is a marker used to measure the extent of damage to the nerve cells.) This trial has 2 parts. The trial doctors will start Part A before starting Part B of the trial. Participants have an option to enter the open label extension after completing Part A or Part B. Part A: Participants will be randomly placed into 1 of the 3 groups. There are equal chances to be assigned to either group. Group 1: Participants will receive NB-4746 capsules at a low dose to take by mouth twice daily for 1 month. Group 2: Participants will receive NB-4746 capsules at a high dose to take by mouth twice daily for 1 month. Group 3: Participants will receive placebo capsules to take twice daily for approximately 1 month. Part B: Participants will be randomly placed into 1 of the 2 groups. There are equal chances to be assigned to either group. Group 1: Participants will receive NB-4746 capsules at a dose determined by Part A to take by mouth twice daily for 12 weeks. Group 2: Participants will receive placebo capsules to take twice daily for approximately 12 weeks. None of the participants, trial doctors, or trial staff will know which treatment the participants will receive during Part A or B. Some trials are done this way because knowing what treatment the participants receive can affect the results of the trial. Doing a trial this way helps to make sure that the results are looked at with fairness across all treatments. Open-Label Extension: Upon the completion of Part A or Part B, the doctor will verify the participant's willingness to continue receiving study treatment. This open label extension continues until each participant completes up to 1 year of treatment. The trial doctors will check participants' ALS and general health throughout the trial.
NCT07659808
This is a multi-center study in which the performance of the Visby Medical Men's Sexual Health Test is evaluated when run by male subjects of 14 years of age and older on self-collected first catch urine samples using the audio-visual instructions provided by the Visby App and/or written instructions provided by the printed User Instructions.
NCT07659301
This study examines whether exposition to hyperbaric oxygen after a road-race simulation can help competitive cyclists recover and perform better the following day. Hyperbaric oxygen, which involves breathing oxygen inside a pressurized chamber, is used as a recovery method in elite and professional sport. Its effectiveness, however, remains controversial: despite this widespread use, there is a lack of solid scientific evidence that a single HBO session after strenuous endurance exercise actually improves recovery, or that clarifies how the amount of oxygen exposure influences any benefit. The study includes healthy male road cyclists between 18 and 40 years of age who compete at the national level in Belgium. After completing a fatiguing cycling session, each participant is randomly assigned to one of four groups receiving different levels of oxygen exposure during recovery. Two groups breathe oxygen under increased pressure inside a chamber at either 2.5 or 1.4 atmospheres absolute. A third group breathes oxygen at normal pressure. The fourth group receives a sham condition that reproduces the treatment setting without active oxygen exposure. The study is double-blind, meaning that neither the participants nor the researchers assessing the outcomes know which condition each participant receives. The main goal is to determine whether a single session of post-exercise HBO improves next-day endurance performance, and whether higher oxygen exposure produces greater effects. The researchers also collect blood samples and physiological measurements to better understand how the body recovers.
NCT07565545
The purpose of this study is to evaluate outcomes in patients treated with iFuse INTRA Ti for chronic SI joint pain.
NCT07660653
This study is a five-arm, parallel-group, assessor-blinded randomized controlled trial designed to evaluate the effects of resistance-dominant multicomponent training combined with nutritional supplementation on intrinsic capacity and disability risk among rural Chinese older adults. A total of 220 participants aged 60 years or older with mobility decline, nutritional risk, sarcopenia risk, or pre-frailty/frailty will be randomly assigned to one of five groups: control, nutrition supplementation alone, resistance training alone, resistance training plus nutrition supplementation, or resistance-dominant multicomponent training plus nutrition supplementation. The intervention will last 12 weeks. Exercise interventions will be conducted three times per week, and nutritional supplementation will include leucine-enriched whey protein and vitamin D. The primary outcomes are the Short Physical Performance Battery score, FRAIL score, and activities of daily living/instrumental activities of daily living scores. Secondary outcomes include gait speed, Timed Up and Go test, sit-to-stand performance, handgrip strength, nutritional status, protein intake, serum 25-hydroxyvitamin D, calf circumference, and appendicular skeletal muscle mass index.
NCT07654231
The overall objective of this pilot randomized clinical trial is to determine whether low-dose Colchicine (LoDoCo) improves vascular disease including vascular calcification, peripheral arterial disease (PAD), and chronic kidney disease-mineral and bone disorder (CKD-MBD) biomarkers in patients with chronic kidney disease (CKD) stage 3 over a 12-month intervention period, compared with usual care. Successful completion of this study will generate critical preliminary data to support a larger clinical trial aimed at evaluating inflammation-targeted therapies to mitigate CKD-MBD, including vascular calcification and related PAD, as well as osteoporosis, ultimately reducing cardiovascular events and mortality in patients with CKD. Additionally, this work has the potential to redefine the diagnostic framework for CKD-MBD.
NCT07661693
This prospective, randomized, double-blind study compares the analgesic efficacy of ultrasound-guided erector spinae plane (ESP) block and subcostal transversus abdominis plane (TAP) block in patients undergoing laparoscopic cholecystectomy. The primary outcome is 24-hour postoperative opioid consumption. Secondary outcomes include postoperative pain scores, time to first analgesic request, shoulder pain, postoperative nausea and vomiting, and block-related complications.
NCT03222531
This is an open-label, pilot trial to test the safety and efficacy of transplantation of hearts from HCV seropositive non-viremic (HCV Ab+/NAT-) and HCV seropositive viremic (HCV Ab+/NAT+) donors to HCV seronegative recipients on the heart transplant waitlist. Treatment and prophylaxis will be administered, using a transmission-triggered approach for the first scenario (HCV Ab+/NAT- donors, arm 1) and a prophylaxis approach for the later scenario (HCV Ab+/NAT+ donors, arm 2).
NCT07426003
This research study is being conducted to determine the effects of enteral nutrition on healthy people. Enteral nutrition for the purpose of this study refers to the use of a specially developed formula taken by mouth that provides all essential nutrition either in the absence of food or to supplement the intake of foods. Enteral nutrition can be used for many reasons, such as to gain or lose weight, to treat food allergies, or to reduce inflammation in certain intestinal diseases. We would like to understand the effects of enteral nutrition in the absence of intestinal inflammation.
NCT07658794
Early allograft dysfunction (EAD) remains one of the most important complications following orthotopic liver transplantation (OLT). Currently, there is no established intraoperative biomarker that reliably predicts graft dysfunction at an early stage. Near-infrared spectroscopy (NIRS) combined with the vascular occlusion test (VOT) is a non-invasive method for assessing tissue oxygenation and microcirculatory reserve. This prospective observational study aims to investigate whether VOT-derived parameters, including desaturation slope, recovery slope and post-ischemic hyperemic area under the curve (AUC-H), can predict EAD in liver transplant recipients. Measurements will be performed at four predefined intraoperative timepoints: after induction of anesthesia, during the anhepatic phase, during the neohepatic phase and at the end of surgery. The primary outcome is the occurrence of EAD according to Olthoff criteria.
NCT05322226
Addiction care is "a la carte treatment", adapted to the motivation and time constrains of users. Thus, various types of psychotherapeutic follow-up can be considered, different addictolytic medications or opioid maintenance therapies can be offered during treatment and hospitalization must be adaptable. In liver transplantation (LT), sustained alcohol relapse is a critical issue because it increases medium and long-term morbidity and mortality. In recent years, the issue of severe acute alcoholic hepatitis as an indication for LT has necessitated increased focus on appropriate alcohol monitoring around liver transplantation. Previously, alcohol consumption in pre- and post-LT period was mainly self-reported. More recently, the biological markers of excessive alcohol consumption have been validated in liver disease and can play a role in liver transplant recipients follow-up. The investigator hypothesize that standardized targeted addiction monitoring of LT patients decreases the rates of sustained alcohol relapse one year post liver transplantation.
NCT07658586
This study aims to develop a comprehensive artificial intelligence model system integrating preoperative multimodal data (CT/MRI imaging, clinical laboratory data, and radiology report text) to achieve two core objectives. First, to develop a multimodal fusion diagnostic model for non-invasive and accurate preoperative differentiation of liver cancer subtypes, including distinguishing benign from malignant lesions and differentiating hepatocellular carcinoma from intrahepatic cholangiocarcinoma. Second, to develop a prognostic prediction model for patients with confirmed liver cancer undergoing radical surgery to assess postoperative progression-free survival and overall survival. This is a multicenter retrospective cohort study with an anticipated sample size of ≥600 patients. Model performance will be evaluated using AUC, accuracy, sensitivity, specificity, C-index, and calibration curves. Subgroup analysis will be conducted based on whether patients received neoadjuvant therapy.
NCT06943664
This phase II trial tests how well photoimmunotherapy (PIT) with ASP-1929 in combination with cemiplimab works in treating patients with stage IIIB-IV non-small cell lung cancer (NSCLC) that has not responded to previous treatment (refractory), that is not suitable for surgery (inoperable), or that has spread from where it first started to other places in the body (metastatic). PIT is a treatment that combines drugs that become active when exposed to light, such as ASP-1929, with immunotherapy to target and kill tumor cells. ASP-1929 combines cetuximab with a light-sensitive component, sarotalocan. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called epidermal growth factor receptor (EGFR), which is found on some types of tumor cells. This may help keep tumor cells from growing. Sarotalocan is a fluorescent dye, infrared-activated fluorescent dye 700, that is light sensitive, and when activated by a special type of laser light, helps destroy or change tumor cells. Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving PIT with ASP-1929 in combination with cemiplimab may kill more tumor cells in patients with refractory, inoperable, or metastatic stage IIIB-IV NSCLC.
