Active clinical trials for "Amyloidosis"

This phase II clinical trial studies the addition of selinexor to lenalidomide in patients with multiple myeloma following transplant. Selinexor is an oral medication approved for use in patients with multiple myeloma following failure of other regimens, and lenalidomide is an oral medication approved for use in patients with multiple myeloma following transplant. This study is testing if the combination of selinexor and lenalidomide is more effective than lenalidomide alone in this setting.

The aging of the population is a reality in our society, with a strong increase in the number of elderly patients hospitalized for heart failure in our institutions. Heart failure in these patients is more present than to younger patients, with preserved ejection fraction form (HFpEF). Aging is responsible for the onset of senile amyloid cardiomyopathy. This pathology is still imperfectly understood and its link with the increase in the frequency of HFpEF is important. In addition, specific treatments have just shown their effectiveness. It is therefore urgent to better identify the prognostic predictive parameters of this cardiomyopathy. The pathophysiological involvement of the coronary microcirculation responsible for a true microvascular coronary disease (CMVD) has been described as predictive factor in all cardiomyopathies. However the implementation of preventive strategies and / or therapeutic of the coronary microcirculation dysfunction are limited because we lack of diagnostic tests available and applicable to large cohorts of patients. Our team INSERM U1039 Radiopharmaceutiques Biocliniques in collaboration with the laboratory GIPSA-lab (Grenoble Images Speech Signal Automatique), laboratory specialized in the signal analysis, has developed a new method of analysis allowing to measure the coronary microcirculation dysfunction usable in SPECT thanks to the measurement of a myocardial perfusion heterogeneity index (IHPM) (patented technique). The 3C registry (NCT03479580) is a registry studying the prevalence and cardiovascular prognosis of macro and microcirculatory coronary artery disease using the latest coronary evaluation techniques in patient with cardiomyopathy. This registry deployed on interventional cardiology centers on the Alpine Arc is therefore also addressed to patients with senile cardiomyopathy. The data collected will provide a better understanding of the factors influencing the prognosis of senile cardiomyopathy and the prognostic contribution of the measurement of the IHPM will be evaluated.

This is a follow-up study of subjects who received NTLA-2001 in a previous clinical trial as an observational evaluation of the long-term effects of the investigational therapy.

The goal of this clinical trial is to learn about malnutrition and weight loss in patients with Amyloidosis. The main question it aims to answer is: Is it feasible to use a low-cost nutrition-based application (apps) for use on a smartphone to obtain detailed information on caloric intake in Amyloidosis patients Participants will be asked to: Download the MyFitnessPal application on their smartphone and view an online tutorial After a week of practice, from weeks 2-9, participants will enter daily dietary intake as well as daily herbal/alternative supplement intake into the MyFitnessPal application on their smartphone. complete a questionnaire prior to starting the application, after week 2 and at week 10 after starting the application

This study evaluates the safety, tolerability, recommended phase II (RP2) dose, and efficacy of Belantamab mafodotin for participants with Relapsed Refractory AL Amyloidosis (RRAL.)

The investigators are researching patients with diseases of their plasma cells in order to improve their quality and length of life. The investigators have created a database of patient information, blood samples, and bone marrow tissue in order to achieve the following three goals: Surveillance: The investigators want to track what treatments patients get or don't get, how effective they are, how they feel, what complications they suffer, how long they stay in remission, and how long they live. Contact: Because myeloma and amyloidosis are rare, less than 700 patients are diagnosed in the state of Ohio each year, patients often feel they don't have accurate information. The investigators want to provide them access to our clinical team (both phone and email consultations, even office visits for patients that can come to Columbus) as well as information regarding informational events pertaining to your disease and local support groups. Research: Because nearly all myeloma and amyloid patients relapse and treatment is eventually unsuccessful, our focus is to develop more effective treatments that not only prolong life, but cure the disease. Periodically the investigators will inform them about clinical trials studying new drugs or treatment paradigms.

This pilot phase I clinical trial studies how well copper 64Cu-DOTA-daratumumab positron emission tomography works in diagnosing patients with multiple myeloma that has come back. Diagnostic procedures, such as copper 64Cu-DOTA-daratumumab positron emission tomography, may help evaluate the extent of multiple myeloma in patients prior to the initiation of treatment and ultimately monitor disease status/response during and post treatment.

Cardiac transthyretin amyloidosis (ATTR), caused by ventricular depositions of misfolded transthyretin, results in an infiltrative cardiomyopathy, progressing from pronounced myocardial wall thickening, diastolic and systolic dysfunction to the development of terminal heart failure. Recently, treatment options for TTR amyloidosis have become available. However costs for therapy are enormous and previous trials were not able to differentiate between patients that might benefit from treatment and those without a need for treatment. the investigators study aims to determine markers, as assessed by cardiac magnet resonance imaging (CMR) feature tracking (FT) and T1- and T2- mapping, that might reliably indicate disease severity and could help to identify patients that might benefit from (ongoing) TTR stabilization treatment.

Cerebral amyloid angiopathy (CAA) is one of the major types of cerebral small vessel disease, and a leading cause of spontaneous intracerebral hemorrhage and cognitive decline in elderly patients. Although increasingly detected, a number of aspects including the pathophysiology, the clinical and neuroradiological phenotype and the disease course are still under investigation. The incomplete knowledge of the disease limits the implementation of evidence based guidelines on patient's clinical management and the development of treatments able to prevent or reduce disease progression. The SENECA (SEarchiNg biomarkErs of Cerebral Angiopathy) project is the first Italian multicentre cohort study aimed at better defining the disease natural history and identifying clinical and neuroradiological markers of disease progression. By a multidisciplinary approach and the collection of a large and well phenotyped series and biorepository of CAA patients, the study is ultimately expected to improve the diagnosis and the knowledge of CAA pathophysiological mechanisms.

Transthyretin is a protein produced in the liver that transports thyroid hormone and vitamin A. A single substitution of an amino acid in the structure of TTR can result in a relatively unstable protein, the breakdown products of which (predominantly monomers) aggregate abnormally and produce proteinaceous deposits in nerves and the heart. These deposits are known as amyloid and produce progressive nerve and heart damage. Amyloidosis due to a mutant TTR is usually an autosomal dominant and hence is a familial condition. Wild-type TTR is also capable of producing amyloid deposits which predominantly involves the heart (rather than the nervous system) resulting in a progressive decrease in cardiac function with increasing signs of heart failure. This study aims to determine whether subcutaneous injection of an antisense oligonucleotide drug, known as ION-682884, that has been specifically designed to reduce production of the protein transthyretin by the liver, can slow or stop the progression of TTR amyloid cardiomyopathy as compared to historical controls, using advanced echocardiography and cardiac MRI. This study drug will only be administered to patients who have completed a 24-month study of a similar drug, inotersen (clinicaltrials.gov identifier NCT037028289).The study also aims to determine the tolerability and safety of this drug when administered over a 36+-month period to patients with TTR amyloid cardiomyopathy. The study duration is open-ended and will continue either until this agent is approved by the FDA, or production is discontinued based on results of ongoing double-blinded studies.
