A Study of Mezagitamab in Adults With Kidney Condition Called IgA Nephropathy

Immunoglobulin A nephropathy (IgAN) is a kidney condition. It happens when the body's immune system creates groups of proteins (called immune complexes) that build-up in the kidneys causing swelling (inflammation). Over time, this inflammation may lead to kidney damage and cause the kidneys to no longer work properly. The main aim of this study is to check how well mezagitamab changes protein levels in the urine (proteinuria) compared to placebo in adults with primary IgAN. A placebo looks like medicine but doesn't have any active ingredients in it. Other aims are to check how safe mezagitamab is and how well participants with primary IgAN can tolerate it compared to placebo, and to find out if and how well mezagitamab continues to maintain kidney function over the long term compared to placebo. Participants will be placed in 1 of the 2 treatment groups; the main group and the open-label group. In the main group, participants will be placed in 1 of the 2 treatment groups by chance (either mezagitamab or placebo) at a 2:1 ratio. This means that out of 3 participants, 2 will receive mezagitamab and 1 will receive placebo. The participants will receive either mezagitamab or placebo for almost half a year in two 1-year cycles. They will be observed for another half year in each 1-year cycle and will have check-ups about every month during this time. In the open-label group, a small number of participants who have lower levels of protein in their urine or have kidneys that do not filter the blood well, will receive mezagitamab treatment. This will include participants who have previously received mezagitamab in another study, TAK-079-1006. Every participant will receive mezagitamab in the same way as those in the main group receiving mezagitamab. During the study, participants will visit their study clinic several times.

Clinical Information System Impact on Hospitalized Patients With Chronic Disease

This is a retrospective, observational study using routinely collected information collected by Alberta Health Services. The study will identify patients with chronic disease, defined by one or more of the following conditions; diabetes mellitus, heart failure, coronary artery disease, chronic kidney disease, or chronic lung disease. Adult residents of Alberta with a chronic disease of interest present upon hospital admission and who survive to hospital discharge will be included in the study cohort. The primary outcome will be the composite of hospital readmission or death within 30 days of discharge. Secondary outcomes will include components of the composite, length of stay, patient experiences related to their hospital to home transition of care, and processes of care. Multi-level interrupted time series analysis will be used to compare outcomes before versus after implementation of the Connect Care CIS.

RaDIANT Health Systems Intervention

The overarching goal of the proposed study is to determine whether the addition of structural interventions at the health system level targeting upstream barriers in the transplant process will improve access to transplant evaluation start.

A Study of GSK4771261 in Healthy Participants Aged 25 to 55 Years of Age Inclusive

This is a first time in Asia (FTIA) study of GSK4771261 in healthy participants of Chinese, Japanese, and White/European ancestry. The study will test whether GSK4771261 is safe, well-tolerated, how it is processed in the body, and whether it triggers an immune response.

Adia Med of Winter Park LLC Chronic Kidney Disease Research Study

The goal of this clinical trial is to learn whether a new regenerative treatment called AdiaVita, made from umbilical cord blood-derived stem cells and exosomes combined with glutathione, is safe and can help improve kidney function in adults with chronic kidney disease (CKD). In this condition, the kidneys gradually lose their ability to filter blood as well as they should. The main questions it aims to answer are whether AdiaVita plus glutathione improves kidney function better than control treatments, as measured by blood tests for estimated glomerular filtration rate (eGFR) and creatinine levels, and whether the treatment is safe with acceptable side effects. Researchers will compare three groups. One group will receive AdiaVita plus glutathione. A second group will receive glutathione plus a placebo for AdiaVita. The third group will receive placebos for both treatments. A placebo looks like the real treatment but contains no active ingredients. This will help determine if the full treatment works better than the controls. Approximately 100 adults aged 18 to 80 with stage 2 to 4 chronic kidney disease may participate. Participants will be randomly assigned to one of the three treatment groups. They will receive monthly intravenous infusions at the clinic for the first three months and apply a skin spray twice daily at home during that period. The study lasts 12 months total for each participant, with regular visits for blood tests, physical exams, and safety monitoring. Certain participants in the control groups may switch to the active AdiaVita treatment after three months if they meet safety criteria. This is a single-blind study, meaning participants will not know which treatment they receive. Participant safety is closely monitored by the research team and an independent board throughout the study.

Red Propolis Supplementation as a Strategy in Chronic Kidney Disease

The objective of this study is to evaluate the effects of red propolis on inflammation and oxidative stress in patients with chronic kidney disease on conservative management.

Immune System Related Kidney Disease

Kidney diseases related to the immune system include, nephrotic syndrome, glomerulonephritis, membranous nephropathy, lupus nephritis, and nephritis associated with connective tissue disorders. This study will allow researchers to admit and follow patients suffering from autoimmune diseases of the kidney. It will attempt to provide information about the causes and specific abnormalities associated with autoimmune kidney disease. Patients with kidney disease as a result of their immune system, and patients with diseases of the immune system who may later develop kidney disease, will be potential subjects for this study. Patients will undergo a history and physical examination, and standard laboratory test to more closely understand the causes, signs, symptoms, and responses to medication of these diseases. Based on these evaluations the patients may qualify as candidates for other experimental studies. At any time these patients may be asked to submit blood or urine samples for further research.

Optimizing Referral Pathways for Patients With Hematuria and Moderate-Severe Proteinuria

The purpose of the study is to evaluate prospectively the impact of an electronic health record (EHR) alert on primary care providers' (PCP) referral to Nephrology of Geisinger patients with high risk signs (blood and protein in the urine) of glomerulonephritis. This will help quantify the relative effectiveness of EHR alerts on PCPs' referral patterns.

How Exercise, a Controlled Diet and Education Improve the Health of People with Early-Stage Renal Failure: A Study at Ciudad Guzmán Hospital

Rutgers University Study of the Genetics of Kidney Disease

The goal of this observational study is to learn more about how genes impact the risk of kidney disease. Anyone 18 or older living in the US is eligible, and a diagnosis of kidney disease is NOT required. Study participation is online, and it takes about 20 minutes to complete health surveys and request a saliva collection kit sent through US mail. In return, study participants may opt to receive information about their genetic ancestry at no cost.

Transgender Analysis of Nephrological Studies Focused on Renal Metrics

This study investigates how sex hormones affect kidney function in people undergoing gender-affirming hormone therapy (GAHT). We know men have a faster progression of kidney disease. Earlier studies suggest that the female sex hormone estradiol may have a protective effect on kidney function while the male sex hormone testosterone may have the opposite effect. But the reasons why this happens remain unclear. By studying participants undergoing (GAHT) we gain insight into the mechanisms by which testosterone and estradiol influence the kidneys. People undergoing GAHT provide a unique chance to study how sex hormones interact with the kidneys. The results may help us to understand why men and women exhibit differences in kidney disease development. This study will include 30 men and 30 women, aged 18 to 40, who start GAHT. Participants will have three study visits, two of which will happen during their scheduled healthcare appointments. During the first visit, a screening will take place to check if patients can take part in the study. At study visits before and after one year of therapy, kidney function is measured, kidney MRI is performed, urine is collected and a small sample of fat tissue. Taking part in the study does not delay the start of GAHT.

Developing a Learning Health System for Primary Care in Thailand

Research question: Can a Learning Health System (LHS) approach improve delivery of care and reduce inequalities in outcomes for people with hypertension and related non-communicable diseases (NCDs) compared to routine care in primary care settings in Thailand? Background: NCDs account for 74% of all deaths in Thailand. Electronic health record data is used in Thailand to monitor how well whole regions deliver care, but is not directly available to healthcare teams in an actionable format which allows them to identify individuals in need of earlier, or more active management. LHS' are an effective framework for empowering healthcare teams to drive quality improvement (QI), reduce inequalities, and translate electronic health record data into actionable clinical insight. Aims and objectives: The investigators will conduct a stratified cluster randomized controlled trial to compare the LHS approach to routine care in two Thai provinces. The investigators will randomize 16 primary care units to the intervention over three phases: targeting management of people with hypertension in phase 1, type 2 diabetes in phase 2 and chronic kidney disease (CKD) in phase 3. In each phase, the investigators will: 1. Co-design a LHS with healthcare teams, policymakers, researchers and the public 2. Train healthcare and analytic teams to deliver the LHS and establish local champions to support it 3. Trial the LHS approach for 12 months 4. Compare performance between intervention and control practices and evaluate the benefits and costs of implementing the LHS 5. Identify provider and patient barriers and facilitators to inform long-term QI for NCDs Methods: The investigators will create four strata of primary care units according to practice size and case-mix. Within each stratum, the investigators will randomize four practices to the intervention arm. In each of the three phases of the intervention, the investigators will hold a series of stakeholder workshops to co-design quality improvement pathways, training materials, and computerised decision support tools (Aim 1); train multidisciplinary healthcare, analytic and research teams to implement the LHS and establish clinical and community champions to support it (Aim 2). The investigators will trial the LHS for 12 months. Monthly data on key metrics will be used to monitor progress and iterate the LHS based on data analytics and shared learning across healthcare teams (Aim 3). The investigators will conduct formal statistical comparisons between intervention and control arms, undertake health economic and mixed-methods realist evaluations to understand what works in promoting change and associated costs and benefits. (Aims 4 \& 5). Timeline: Trial setup (months 0-6), Hypertension (months 3-21), Diabetes (months 15-33), CKD (months 24-45), Evaluation (months 24-48) Impact and dissemination: Results will be disseminated via publication in high-impact journals, conference presentations, stakeholder meetings, and the media. The investigators will co-produce locally relevant educational materials and clinical guidelines. Impact will include the generation of longitudinal epidemiological data on management and outcomes of NCDs, including factors which facilitate continuous QI, and associated costs and benefits. The decision support tools, training resources, and economic evaluative frameworks will be made freely available by the Thai Ministry of Health and the regional WHO office. Capacity building will ensure the next generation of clinical, community, and research leaders promulgate this way of working across the region.

Renal and Hepatic Abnormal Doppler Patterns in Trauma

The goal of this observational study is to learn about renal and hepatic blood flow abnormalities detected by bedside ultrasound in adult patients admitted to the intensive care unit (ICU) following major trauma. The main questions it aims to answer are: * How reliably can trained operators measure renal Doppler and venous congestion scores (RDRI and VExUS) across different hospitals? * How common are abnormal kidney and liver blood flow patterns in major trauma patients during the first 72 hours of ICU admission? * Are these abnormal patterns associated with acute kidney injury or the need for mechanical ventilation? Participants admitted to ICUs or high-dependency units (HDUs) with major trauma (Injury Severity Score \>15) will undergo non-invasive bedside ultrasound assessments at admission and at 24, 48, and 72 hours. No additional treatments or interventions will be given as part of this study. Kidney function will also be checked at 6 months after hospital discharge.

Digital Support for Reducing Salt Intake Among Patients With Diabetic Kidney Disease: Protocol for a Controlled Clinical Trial

Sensor-based Congestion ALert for Events in Peritoneal Dialysis (SCALE-PD)

To explore the use of the Bodyport Cardiac Scale in predicting worsening of events due to fluid overload in patients with kidney disease on peritoneal dialysis.

A Study of Eloralintide (LY3841136) in Participants With Renal Impairment and in Participants With Normal Renal Function

The purpose of the study is to assess the amount of Eloralintide (LY3841136) that reaches the bloodstream and the time it takes for the body to get rid of it when given to participants with renal (kidney) impairment and to healthy participants. The study drug will be administered subcutaneously (SC) (under the skin). For each participant, the study will last about 14 weeks, excluding screening.

Older Kidney Patient Optimisation Pretransplant

The goal of this clinical trial is to learn if a kidney transplant-specific comprehensive geriatric assessment (KT-CGA) can improve the way older adults are assessed for kidney transplantation. The main questions it aims to answer are: Is it feasible and acceptable to deliver a KT-CGA alongside routine transplant assessment in older adults with advanced kidney disease? What is the effect of KT-CGA on decision-making about transplant listing and on patient-reported outcomes such as quality of life and frailty? Researchers will compare participants who receive the KT-CGA plus usual care to those who receive usual care alone. Participants will: Continue with their usual transplant assessment process If randomised to the intervention group, also complete the KT-CGA (a structured set of questionnaires, short memory and function tests, and discussions about wellbeing and support needs, taking about 45-60 minutes)

Cobas® Lumira Collection of Venous and Capillary Blood Samples for the Research, Optimization and Calibration of New Diagnostic Devices

This study is a blood sample collection study, collecting venous and capillary blood samples from adult patients in the UK, with a range of health conditions. The purpose of this study is to collect blood samples to help develop, improve, and fine-tune new and existing diagnostic tests for the cobas® lumira instrument. This instrument is a diagnostic medical device with single-use test strips, that allows diagnostic testing right at the patient's side. The aim is to improve doctors' ability to monitor health conditions more quickly and easily. Approximately 30,000 patients are expected to participate in this study, across multiple UK sites.

Randomized Trial of SGLT2i in Heart Transplant Recipients

Heart transplant (HTx) is an established therapy for advanced heart disease that restores quality of life and improves survival. However, due to preexisting comorbidities combined with the immunosuppressive therapies required after transplantation, HTx recipients remain at high risk for kidney, cardiovascular (CV), and metabolic disease. Large randomized clinical trials have recently shown that sodium-glucose cotransporter 2 inhibitors (SGLT2i) have potent kidney protective and CV benefits in many populations of patients with chronic kidney disease (CKD), CV disease and/or diabetes. SGLT2i have not been studied prospectively in HTx recipients, which represents a barrier to their use in this population. In this multicenter randomized controlled trial in Veterans with HTx, investigators will evaluate the potential benefits of empagliflozin on kidney function, cardiometabolic risk, erythropoiesis, and functional status. A total of 200 Veterans will be randomly assigned to receive either empagliflozin 10 mg daily or a matching placebo for 12 months.

Inspire HER: Inspiring the Heart and Emotions for Radical Health

Poor heart health puts Black women at risk for a shorter life with more illness than people of any other non-indigenous racial group. We will refine and conduct a randomized, wait-list controlled trial of Inspire HER (a heart health lifestyle intervention for Black women that provides health education, physical activity, and social resources). We will also compare Inspire HER and Black Impact (a heart health intervention for Black men) data to study how women and men respond differently to stress. This trial aligns with American Heart Association's pledge to address heart health equity through new interventions that consider the person and the circumstances with which they live.

Identification and Characterisation of IgA With Nephritogenic Potential in IgA Deposition Nephropathies (Rep-IgAN)

IgA nephropathy (IgA Nephropathy), or Berger's disease, is the most common form of primary glomerulonephritis. It is a major cause of end-stage renal failure, often leading to dialysis or kidney transplantation. Recurrence is common after transplantation, compromising graft survival. Rheumatoid purpura (or IgA vasculitis) shares a common pathophysiology with IgA N, characterised by mesangial deposits containing IgA-rich immune complexes, but differs in its systemic involvement (skin, joints and digestive system). In terms of pathophysiology, the histological signature of these conditions is based on the accumulation of abnormal IgA within the glomerulus. The mechanisms responsible for the nephrotoxicity of these IgA remain partially unclear. In patients with NIgA, several qualitative abnormalities of IgA have been well described, including a glycosylation defect that promotes IgA polymerisation and the emergence of anti-IgA autoantibodies. These immune complexes, found in glomerular deposits, induce a local inflammatory reaction. Experimental work conducted on mouse models developed at the CRIBL laboratory has shown that these abnormalities may be linked to a dysregulation of the immune response, leading to the production of IgA with physicochemical properties that promote their deposition in the kidney. However, the location of nephritogenic IgA-secreting B cells remains poorly understood. Recent data suggest that this production could occur directly within the renal parenchyma, where activated B lymphocytes would locally produce pathogenic IgA. Following on from these observations, our study aims to characterise the immunoglobulin (Ig) repertoires in patients with IgA nephropathy, particularly those from renal lymphoid infiltrates, and to compare them with the repertoires of circulating B cells. We hypothesise that certain sequence motifs within the variable domains of IgA, particularly the CDR3 regions, could constitute specific biomarkers of NIgA. Their detection in peripheral blood could enable non-invasive or predictive diagnosis, complementing the renal biopsy that is currently essential.

Long-term Follow-up of the Offspring Born to Mothers With a Solid Organ Transplant, Transplantlines Next Generation

Background Pregnancy after all types of solid organ transplantation (SOT) is possible, although these have higher risk of pregnancy complications for mother and child, such as preeclampsia and preterm birth. Thus, the development of the unborn child seems to be affected by the transplant and its consequences such as the immunosuppressive medication use. Worldwide data regarding follow-up after birth is scarce. The very limited existing data existing only in young children are reassuring. However, the investigators hypothesize that there are health risks for the children. Given the side effects of the immunosuppressive medication on patients and limited knowledge from animal studies, the investigators particularly expect cardiovascular effects such as hypertension and kidney damage. These develop over a long time-period and lead late to symptoms. Aims Aim of this study is to gain more insight into the overall health of offspring born after SOT. Primary aim is to assess the cardiovascular health and the presence of kidney disease, and compare these with reference values from the general population or birth cohorts. Secondary aims are the immunological status including the microbiome of the child given the maternal immunosuppressive medication use, and the overall development of the offspring, including qualitative research regarding the quality of life. Third aim is to assess if there are differences in health between offspring born to mothers with a kidney, liver, pancreas (including pancreas islet), heart and lung transplantation (KTx, LiTx, PTx, HTx, LuTx resp.). The investigators also want to establish a biobank for later follow-up research. Study design This will be a cross-sectional monocenter cohort study. All offspring ≥16 years of age born after KTx or LiTx and all offspring born at any age after PTx, HTx and LuTx in the Netherlands will be eligible for inclusion. The investigators estimate that there will be about 150(-220) participants. Before the study visit, participants will be asked to complete a questionnaire. Participants will be invited for a one-time study visit consisting of physical tests (including ultrasound of the kidneys and a 24-hour ambulatory blood pressure measurement) and biological sample (urine, blood and feces) collection, including sample collection for biobanking. Information about the growth and development of the offspring and, if present, diseases and medication use will be collected from the medical files of the general practitioner and pharmacy (LSP) and from data from the youth healthcare check-ups. As a control group pseudoanonymized data from the Lifelines cohort will be used. Deliverables To the best of our knowledge, this will be the first study worldwide that will gather and analyze detailed information about the cardiovascular, kidney and immunological health at a later age (≥16 years) in the offspring born to mothers after KTx, LiTx, PTx, HTx and LuTx. This information will be important for the preconceptional counseling of families with a pregnancy wish after transplantation and thereby contribute to the health of women with a SOT. Next to that, find adverse effects of the pregnancy after transplantation on the offspring are found, the investigators expect there will be modifiable factors and/or early screening/interventions that can reduce these risks and thereby contribute to the health of the offspring.
