Transthyretin (TTR) is a plasma protein mainly synthesized in the liver, recognized as a transporter of thyroxine and retinol-binding protein. Unstable changes in two types of TTR (wild type or variant) become misfolded, aggregate, and ultimately forms amyloid fibrils. Amyloid Transthyretin Cardiac amyloidosis (ATTR-CA) is an infiltrative cardiomyopathy caused by extracellular deposition of insoluble transthyretin (TTR) amyloid fibrils in the heart muscle. Cardiac amyloidosis (CA) has been recognized as a common cause of heart failure with preserved ejection fraction (HFpEF) among elderly persons, with increasing incidence. There are different ways of diagnosing ATTR-CA. These include cardiac magnetic resonance imaging, nuclear scintigraphy, and tissue biopsy, the gold standard. Tissues biopsy extracted from the adipose, lip salivary gland (LSG), and heart muscle (endomyocardial biopsy or EMB). Tissue diagnosis is the prerequisite of provincial support of the disease-modifying agent. However, with the convenience, ease, less risk of bleeding, and high sensitivity, LSG may offer an alternative to the more invasive EMB to diagnose suspected CA. To test the hypothesis that LSGB can replace EMB in tissue diagnosis of ATTR-CM. This Pilot study is designed to evaluate two invasive diagnostic methodologies: LSGB and the EMB. A total of 20 patients who underwent EMB within the last six months with confirmed Amyloid Transthyretin -wild type (ATTRwT) will be invited to participate. In addition, patients who signed the informed consent form will be scheduled for LSGB within two weeks.
The purpose of the study is to evaluate and compare different tools that are used to detect evidence of peripheral neuropathy in patients with TTRv.
The primary aim is to establish a prospective cohort of patients with plasma cell disorders (PCDs). All of the hospitalized PCD patients who are willing to sign the informed consent form (ICF) will be included in this study. Clinical characteristics, treatment options and responses will be collected. Peripheral blood, bone marrow aspirate and urine samples before and after the treatment will banked for future research. Our team will focus on the clinical and pathological features of PCDs, the correlation between the minimal residual disease (MRD) status and prognosis, and the role of Tumor Microenvironment (TME) in the pathogenesis and progress of PCDs.
The purpose of this protocol is to generate a registry of Chinese patients with AL amyloidosis treated with subcutaneous/intravenous daratumumab alone or subcutaneous/intravenous daratumumab combined with chemotherapy.
A Clinical Study on the Safety and Effectiveness of CD19/BCMA Chimeric Antigen Receptor T Cells in the Treatment of Refractory POEMS Syndrome, Amyloidosis, Autoimmune Hemolytic Anemia, and Vasculitis
It is essential to improve clinical efficiency and management of hematological and oncological patients treated on an outpatient basis. The most promising operative way to achieve this result is the development of tele-oncology platforms, that allow not only a telemedicine visit, but also the patient support in the daily management of the disease and related disorders, as well as treatments and their complications. In this perspective, the RITA communication platform should be able to support the patient, the caregiver, the physician and the general practitioner in the management of the disease and its treatments.
The investigators will evaluate the change in myocardial uptake of 99m-technetium pyrophosphate (Tc-99m PYP) tracer on serial planar and SPECT imaging in patients enrolled in the CARDIO-TTRansform clinical trial (NCT04136171).
The purpose of this study is to characterize cardiac safety of Daratumumab, Cyclophosphamide, Bortezomib, and Dexamethasone (D-VCd) treatment regimens (Arm A: daratumumab + immediate VCd treatment and Arm B: daratumumab + deferred VCd) in newly diagnosed systemic amyloid light chain (AL) amyloidosis with cardiac involvement and to identify potential mitigation strategies for cardiac toxicity (cohort 1); to characterize the pharmacokinetics of subcutaneous (SC) daratumumab, among racial and ethnic minorities, including Black or African American, with newly diagnosed AL amyloidosis treated with D-VCd (cohort 2).
This study is designed to assess the repeatability of organ-specific quantitation of radiotracer uptake following Positron Emission Tomography/Computed Tomography (PET/CT) imaging of AT- 01 in subjects with amyloid light chain (AL) or amyloid transthyretin (ATTR) systemic amyloidosis.
