Filter by:This is an open-label, multicenter, Phase 2 study in subjects with newly diagnosed systemic light chain (AL) amyloidosis. Approximately 40 subjects will receive therapy with bortezomib, pomalidomide, and dexamethasone. The primary outcome is hematologic very good partial response and complete response rate at 6 months.
This single-practice prospective cohort study aims to enhance the diagnosis of cardiac amyloidosis in high-risk patients undergoing standard cardiac device implantation. By analyzing chest wall fat tissue, which is usually discarded, we aim to determine the diagnostic yield of such biopsies for amyloidosis and to develop a predictive screening model based on clinical, lab, and imaging data. The study, running from December 2023 to December 2024, expects to enroll 100 patients and may provide a new, non-invasive diagnostic avenue for this condition.
The goal of this research study is to determine whether changes in organ-specific uptake of 124I- AT-01 can be measured by PET/CT imaging and further, whether these values correlate with changes in a subject's disease status and thereby enable monitoring of disease response over time in terms of organ-specific amyloid load.
This study will investigate 99mTc-p5+14, an amyloid-reactive synthetic peptide, p5+14, radiolabeled with technetium-99m, as a radiotracer for detecting paamyloid deposits in patients with AL or ATTR-associated systemic amyloidosis, notably with cardiac involvement.
This study is based on the hypothesis that MRI could make it possible to non-invasively detect these amyloid deposits at the level of the wrist using parametric sequences known as T1 mapping, in the form of an extension of T1 in the wrists. areas where amyloid deposits are found in the wrist.
Systemic amyloidosis is a multi-system disease caused by extracellular deposition of insoluble amyloid fibrils in various tissues and organs, leading to progressive organ dysfunction. The clinical manifestations of different types of amyloidosis are complex and diverse, and the prognosis is very poor. Early detection and classification of amyloid deposition is becoming increasingly important. However, conventional imaging techniques including ultrasound and magnetic resonance are not sensitive or specific. Endocardial biopsy is the gold standard for the diagnosis of cardiac amyloidosis, but it is an invasive procedure with a clinical complication rate of 6%. Positron emission tomography (PET) provides a valuable tool for diagnosing systemic amyloidosis. Recently, amyloid PET imaging agents (11C-PIB or 18F-florbetapir) have been shown to be effective as novel positron tracers to detect potential amyloid deposition in some small sample studies. The investigators will use the most advanced imaging equipment, integrated PET/MR with amyloid PET imaging agents(11C-PIB or 18F-florbetapir) to image patients suspected or confirmed systemic amyloidosis, the aim is to explore the value of hybrid PET/MR for systemic amyloidosis.
This is a single-center, exploratory, Phase 1 Positron Emission Tomography/x-ray Computed Tomography (PET/CT) imaging study to detect amyloidosis that will enroll patients with a confirmed diagnosis of systemic amyloidosis. The purpose of this exploratory trial is to assess the safety and efficacy of 124I-p5+14 Injection at a single-injection dose adequate for imaging amyloid deposits by using PET/CT imaging in subjects with confirmed systemic Immunoglobulin Light Chain-associated Amyloidosis (AL), Transthyretin-associated Amyloidosis (ATTR), Leukocyte Chemotactic Factor 2-associated Amyloidosis (ALect2) as well as other types.
