NCT ID: NCT06278337 Recruiting - Autoimmune Diseases Clinical Trials

X-linked Moesin Associated Immunodeficiency

Start date: August 12, 2021
Study type: Observational

Moesin deficiency was initially described in 7 male participants aged 4 to 69 years and is characterized by lymphopenia of the 3 lineages and moderate neutropenia. Genetically, 6 out of 7 participants had the same missense mutation in the moesin gene located on the X chromosome. The 7th patient has a mutation leading to the premature introduction of a STOP codon into the protein.Clinically the 7 participants with X-linked moesin-associated immunodeficiency all presented with recurrent bacterial infections of the respiratory, gastrointestinal or urinary tracts, and some had severe varicella.Therapeutically, in the absence of a molecular diagnosis and due to his SCID-like phenotype, one patient was treated with geno-identical hematopoietic stem cell transplantation . The remaining are untreated or treated with immunoglobulin substitution and/or prophylactic antibiotics. Since this study, the moesin gene has been integrated into DNA chips used for the molecular diagnosis of immune deficiencies in several countries. Physicians in Canada, the United States, Japan, South Africa and Europe have contacted us with a total of 16 known participants to date. Because of their very low severe, uncontrolled CMV infection and the absence of treatment recommendations, two 2 American participants were treated with allogeneic transplantation with severe post-transplant complications (1), and one of the participants died as a result of the transplant. Management of XMAID participants therefore varies widely from country to country, depending on age at diagnosis and clinical picture. It ranges from no treatment treatment (associated with recurrent infections and skin manifestations), IgIv substitution and/or antibiotic prophylaxis antibiotic prophylaxis, with low toxicity and apparent efficacy, and allogeneic transplantation, with all the risks risks involved (graft-related toxicity, graft versus host, disease, rejection, risk of infection). The Investigators therefore feel it is important to review the diagnosis, clinical presentation and management of X-MAID participants. The study the investigator propose will enable to understand the presentation of X-MAID participants, establish guidelines and provide the best treatment for each patient according to his or her clinical picture

NCT ID: NCT06275958 Not yet recruiting - Colorectal Cancer Clinical Trials

DOSAGE Study: Upfront Dose-Reduced Chemotherapy in Older Patients With Metastatic Colorectal Cancer

Start date: June 2024
Phase: Phase 3
Study type: Interventional

The goal of this phase III, open-label, non-inferiority randomized controlled clinical trial is compare upfront dose-reduced chemotherapy with the standard dose chemotherapy in older patients ( ≥70 years) with metastasized colorectal cancer, with regard to progression-free survival (PFS). The choice between monotherapy (a fluoropyrimidine) and doublet chemotherapy (a fluoropyrimidine with oxaliplatin) will be made for each individual patient based on expected risk of chemotherapy toxicity (according to the G8 screening). Patients classified as low risk of toxicity will be randomized between doublet chemotherapy in either full-dose, or with an upfront dose-reduction of 25%. Patients classified as high risk will be randomized between monotherapy in either full-dose or upfront dose-reduction. Primary outcome is PFS. Secondary endpoints include grade ≥3 toxicity, QoL, physical functioning, overall survival, number of treatment cycles, dose reductions, hospital admissions, cumulative received dosage and cost-effectiveness.

NCT ID: NCT06275776 Not yet recruiting - Clinical trials for Wound Healing Disturbance of

HIP-STITCH (Wound Recovery After THA)

Start date: March 1, 2024
Phase: N/A
Study type: Interventional

This prospective randomised trial will investigate the effect of four different suturing techniques (Monocryl, Vicryl Rapide with Indermil skin glue, Dermabond Prineo, and Stryker Zip) on the amount of aberrant wound recovery within 14 days after total hip arthroplasty at the RHOC in Zoetermeer, The Netherlands. This will be done by assessing photographs of the plaster and photographs of the operation wound with a self-developed classification model. The photographs of the plaster will be taken by the test subject at home at 3 days and 11 days postoperatively. The photographs of the operation wound will be taken by a member of the research team, and the doctor's assistant, respectively, during a visit to the outpatient clinic at 7 days and 14 days postoperatively. Hypothesis: Monocryl sutures give the highest amount of aberrant wound recovery within fourteen days after primary THA.

NCT ID: NCT06273865 Not yet recruiting - Hemophilia A Clinical Trials

Version Testing of EnzySystem Version A for Hemophilia A

Start date: March 15, 2024
Study type: Observational

Background of the study: To measure blood clotting, blood is taken from a vein. This blood is processed in the laboratory and then tested. A new device has been developed that requires only a very small volume of blood (5-10 drops of blood) to perform the laboratory tests. The long-term goal is that this device can be used by a doctor or at home to quickly measure blood clotting. In this research we want to compare this new system with the standard methods - measurement in the laboratory - and evaluate whether the correct value is determined. Objective of the study: The primary objective of this study is to demonstrate that the EnzySystem HemA version A can record thrombin generation TG and quantify FVIII activity levels within a time frame of 60 min in fresh whole blood samples of healthy volunteers and patients with hemophilia A in the Enzyre laboratory (for healthy volunteers) and the Radboudumc (for patients with hemophilia A). Study design: This is a cross-sectional observational study. All participants are asked to fill a questionnaire prior to blood collection. The blood of healthy volunteers will be collected in an office of Enzyre BV, the blood of patients will be collected in the Radboudumc. Blood collection, by venepuncture, will be conducted by a Radboudumc research nurse or physician of the research team in both locations. In total, four blood tubes with citrate as anticoagulant will be drawn (a total of around 11 mL). Study population: The study population consists of 20 healthy volunteers: evenly distributed between male and female; ages spread over the range from 20 to 70 years old; recruited by Enzyre via advertisement. 20 Patients: 5 severe hemophilia A; 5 moderate hemophilia A; 10 mild hemophilia A; recruited from the Hemophilia Treatment Center (HTC) Nijmegen-Eindhoven-Maastricht (NEM) (location Radboudumc). Primary study parameters/outcome of the study: Demonstrate that the EnzySystem HemA version A can record TG and quantitative FVIII activity levels within a time frame of 60 min in fresh blood samples of healthy volunteers and patients with hemophilia A. Secondary study parameters/outcome of the study (if applicable): Secondary study parameters are composed whether the measured values comply with the desired assay specificity and accuracy. Outcomes are analysed for equivalence compared to one-stage FVIII assay, FVIII chromogenic assay, thrombin generation via the Nijmegen Hemostasis Assay, and possibly via the Technoclone assay. Is it possible to measure FVIII activity with the EnzySystem HemA version A in fresh blood samples of healthy volunteers and patients with hemophilia A, compared to the gold standard with; - Precision in the normal range (60-140%): min. 30% - Precision in the low range (3-10%): min. 50% - Limit of Detection range min. 100 % FVIII activity - Limit of Detection low range min. 3 % FVIII activity Is it possible to measure TG with the EnzySystem HemA version A in fresh blood samples of healthy volunteers and patients with hemophilia A, compared to the gold standard with; - Precision in the normal range (60-140%) of control samples: min. 30% - Precision in patient with hemophilia A: min. 50% - Limit of Detection, high range > 400 nM thrombin activity - Limit of Detection measured with Plasma, low range < 50 nM thrombin Other study parameters All samples will also be tested for other hemostasis specific parameters as these parameters may affect a proper measurement of both FVIII activity and Thrombin Generation. The following parameters will be measured in plasma obtained from the whole blood vacutainers. Moreover, left over samples (plasma) will eventually be used to develop other coagulation related parameters. - von Willebrand Factor antigen levels - von Willebrand Factor ristocetin activity levels - Prothrombin Fragment 1+2 levels - ADAMTS13 activity - FVIII antigen levels - blood group

NCT ID: NCT06273800 Not yet recruiting - Breast Cancer Clinical Trials

NCT ID: NCT06273176 Recruiting - Glioblastoma Clinical Trials

The RECMAP-study: Resection With or Without Intraoperative Mapping for Recurrent Glioblastoma

Start date: January 1, 2023
Study type: Observational

Resection of glioblastoma in or near functional brain tissue is challenging because of the proximity of important structures to the tumor site. To pursue maximal resection in a safe manner, mapping methods have been developed to test for motor and language function during the operation. Previous evidence suggests that these techniques are beneficial for maximum safe resection in newly diagnosed grade 2-4 astrocytoma, grade 2-3 oligodendroglioma, and recently, glioblastoma. However, their effects in recurrent glioblastoma are still poorly understood. The aim of this study, therefore, is to compare the effects of awake mapping and asleep mapping with no mapping in resections for recurrent glioblastoma. This study is an international, multicenter, prospective 3-arm cohort study of observational nature. Recurrent glioblastoma patients will be operated with mapping or no mapping techniques with a 1:1 ratio. Primary endpoints are: 1) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks, 3 months, and 6 months after surgery and 2) residual tumor volume of the contrast-enhancing and non-contrast-enhancing part as assessed by a neuroradiologist on postoperative contrast MRI scans. Secondary endpoints are: 1) overall survival (OS), 2) progression-free survival (PFS), 4) health-related quality of life (HRQoL) at 6 weeks, 3 months, and 6 months after surgery, and 4) frequency and severity of Serious Adverse Events (SAEs) in each arm. Estimated total duration of the study is 5 years. Patient inclusion is 4 years, follow-up is 1 year. The study will be carried out by the centers affiliated with the European and North American Consortium and Registry for Intraoperative Mapping (ENCRAM).

NCT ID: NCT06270628 Not yet recruiting - Neoplasms Clinical Trials

Personalized Live-remote Exercise Training for Cancer Survivors

Start date: February 20, 2024
Phase: N/A
Study type: Interventional

Background Many people with cancer face ongoing problems from their disease and treatments, like fatigue, reduced physical fitness, feeling anxious or down, and neuropathy. While exercise might help with these problems, most studies did not focus on tailoring exercise to address these specific complaints. Exercise programs under supervision (like with a trainer) seem to work better, but barriers for following such sessions are travel distance and time. Therefore, following an exercise program at home with a trainer guiding via video (live-remote) might be a good solution. But, it is unclear how effective this remote exercise program is for cancer patients. Goal of the study: The main goal of this study is to assess the effectiveness of a personalized, live-remote exercise intervention for cancer survivors on quality of life and the patients' main complaint. The four complaints tackled in this study are: 1) fatigue, 2) reduced physical functioning, 3) anxiety and/or depressive symptoms, and 4) neuropathy. Design of the study In the LION study, 350 cancer patients will be randomly divided into the exercise group or control group. These patients all have at least one of these complaints: 1) fatigue, 2) reduced physical functioning, 3) anxiety and/or depressive symptoms, and/or 4) neuropathy. Patients cannot participate in the study if they are already very active. The exercise group will start a 12-week exercise program right away, and the other group will wait for 12 weeks before starting. The exercise program consists of three sessions per week. Two sessions per week include aerobic training and strength training. These sessions will be followed by all patients; and aim to improve fitness and strength. The third session specifically aims at improvement of the main complaint, for example fatigue. Participants will get an app and a fitness tracker to help them stay on track with their exercises. Furthermore, patients get information on the effects of exercise for cancer patients and why exercise is important for specific complaints. Measurements The main outcomes of this study are quality of life and the main side-effect of the patient. Other measurements include all kind of patient reported outcomes (like sleep problems and pain), physical fitness, muscle strength, balance, anthropometrics, and (inflammatory) markers in blood. Conclusion: This study investigates if personalized exercises done at home, with video guidance, can make cancer survivors feel better and manage their side effects more effectively.
