Repeat PET/CT Imaging in People With CAPS and Anakinra-Induced Amyloidosis Using an Amyloid-Reactive Peptide to Measure Changes in Organ-Specific Amyloid Load
Description

Background: Anakinra is a drug used to treat people with certain diseases that affect their immune systems. Sometimes anakinra can cause proteins under the skin to clump together. These clumps are called amyloidosis; they can spread to other organs. The only way to diagnose amyloidosis is to remove a piece of tissue (biopsy). Researchers want to find a way to locate amyloidosis in internal organs using positron emission tomography (PET)/computed tomography (CT). Objective: To test a new tracer used during PET/CT scans in people with amyloidosis. A tracer is a radioactive dye injected into the body. Eligibility: Adults aged 18 years or older with amyloidosis from anakinra injections. They must be enrolled in NIH protocol 17-I-0016. Design: Participants will come to the clinic once every 6 months for 2 years. Each visit will be 1 day. They will have a PET/CT scan with the new tracer at each visit: The tracer will be given through a tube attached to a needle inserted into a vein. The PET/CT scanner is a machine shaped like a doughnut. Participants will lie still on a padded table. The table will move in and out of the machine. The scan takes about 1 hour. Radiation from the tracer will remain in the body for 24 hours after each scan. Participants will need to follow rules to avoid exposing pets and other people. Participants will collect a 24-hour urine sample before each visit. They will also have blood tests and a physical exam at each visit. Participants will receive a follow-up phone call about 1 week after each visit.

Acoramidis Transthyretin Amyloidosis Prevention Trial in the Young (ACT-EARLY) Study in Asymptomatic Carriers of a Pathogenic TTR Variant
Description

Transthyretin amyloidosis (ATTR) is a disease where the normally occurring transthyretin (TTR) protein falls apart and forms amyloid, a sticky plaque- like substance that accumulates in different organs in the body and can cause damage to the organ. There are two ways that the TTR protein can fall apart. One way occurs as a person ages, where the normal TTR protein can fall apart and form amyloid that may no longer be sufficiently cleared by the body. This type of ATTR is known as wild-type ATTR (ATTRwt). The other way occurs when a person inherits a defective TTR gene that causes the TTR protein to spontaneously fall apart. This form of the disease is known as variant ATTR (ATTRv) and can be detected in adults by a genetic test of their TTR gene before they age. Amyloid build-up in the heart causes the heart wall to become thick and stiff and can result in heart failure and even death. Accumulation of TTR amyloid in the heart is known as transthyretin amyloid cardiomyopathy or ATTR-CM. Amyloid can also deposit in the nerve tissues leading to nerve problems. Accumulation of TTR in the nerves is known as transthyretin amyloid polyneuropathy or ATTR-PN. Acoramidis is an experimental drug designed to bind tightly to TTR in the blood and stabilize its structure, so it does not form the harmful amyloid plaques that can cause damage to organs. This study is intended to determine if treatment with acoramidis in participants with ATTRv who have not yet developed any symptoms of disease can prevent or delay the development of ATTR-CM or ATTR-PN disease. If adults with an inherited defective TTR gene are treated early before any of the symptoms of disease have developed, it may be possible to delay the onset or prevent the disease entirely.

Carpal Tunnel Release With Risk Factors for Amyloidosis
Description

Bilateral carpal tunnel syndrome has been demonstrated in previous literature to be a warning sign for potential amyloidosis. One study has been performed in which patients with bilateral carpal tunnel syndrome underwent tissue biopsy (either tendon sheath or transverse carpal ligament) at the time of carpal tunnel release to determine the strength of association as well as most common subtypes. However, no study has been done demonstrating whether or not patients with amyloid-positive carpal tunnel biopsy would benefit from an early referral to cardiology for a work-up of potential cardiac amyloidosis. In our study, patients with bilateral carpal tunnel symptoms who are indicated for carpal tunnel release would be identified in clinic and undergo biopsy for congo red staining at the time of surgery. All patients with positive biopsy results would be referred to cardiology. Outcomes would include the rate of amyloid positivity, common subtypes, and echocardiographic findings after cardiac referral.

Characterizing Iodine-124 Evuzumitide (AT-01) in Systemic Amyloidosis
Description

This is a single center prospective study evaluating 124I-evuzumitide in patients with systemic amyloidosis. The purpose of this study is to 1)identify and characterize the distribution and uptake of 124I-evuzumitide in patients with transthyretin amyloid cardiomyopathy (ATTR-CM) and 2) Correlate the uptake with the structure and function of different organs, including the heart. To achieve these goals, eligible patients will undergo primarily hybrid positron emission tomography and magnetic resonance imaging (PET/MRI). In a subgroup of patients who are unable to undergo PET/MR, computed tomography will be used instead of MRI (i.e. PET/CT). In a subgroup of patients, repeat imaging with the same modality will be done at a interval of 6-12 months. Clinically available data (demographics, phenotype, imaging, laboratory) will also be collected to characterize the disease in each patient.

Molecular Imaging of Myocardial Fibrosis in Cardiac Amyloidosis
Description

The primary aim of our pilot study is to determine whether fibrosis in the heart can be measured with \[68Ga\]CBP8, a positron emission tomography (PET) probe, using PET/magnetic resonance imaging (MRI) imaging, in 30 individuals with documented cardiac amyloidosis. The investigators will also enroll 15 individuals with recent myocardial infarction and 15 individuals with hypertrophic cardiomyopathy as positive controls for fibrosis, and the investigators will enroll 5 individuals without cardiovascular disease to undergo \[68Ga\]CBP8 PET/MRI imaging as a healthy control group. The primary hypothesis of this study is that \[68Ga\]CBP8 will bind to interstitial collagen and quantify myocardial fibrosis in patients with cardiac amyloidosis. The investigators hypothesize that \[68Ga\]CBP8 uptake will be greater in patients with cardiac amyloidosis, myocardial fibrosis, and hypertrophic cardiomyopathy than in healthy controls. Secondly, the investigators also hypothesize that \[68Ga\]CBP8 activity more strongly correlates with standard MRI measures in patients with recent myocardial infarction and hypertrophic cardiomyopathy (where extracellular expansion is caused by myocardial fibrosis/collagen deposition) than in patients with cardiac amyloidosis (where myocardial fibrosis is combined with infiltration).

Subclinical Transthyretin Cardiac Amyloidosis in V122I TTR Carriers
Description

Approximately 1.5 million of the 44 million Blacks in the United States are carriers of the valine-to-isoleucine substitution at position 122 (V122I) in the transthyretin (TTR) protein. Virtually exclusive to Blacks, this is the most common cause of hereditary cardiac amyloidosis (hATTR-CA) worldwide. hATTR-CA leads to worsening heart failure (HF) and premature death. Fortunately, new therapies that stabilize TTR improve morbidity and mortality in hATTR-CA, especially when prescribed early in the disease. However, hATTR-CA is often diagnosed at an advanced stage and conventional diagnostic tools lack diagnostic specificity to detect early disease. The overall objectives of this study are to determine the presence of subclinical hATTR-CA and to identify biomarkers that indicate amyloid progression in V122I TTR carriers. The central hypothesis of this proposal is that hATTR-CA has a long latency period that will be detected through subclinical amyloidosis imaging and biomarker phenotyping. The central hypothesis will be tested by pursuing 2 specific aims: Aim 1) determine the association of V122I TTR carrier status with CMRI evidence of amyloid infiltration; Sub-aim 1) determine the association of V122I TTR carrier status with cardiac reserve; Aim 2) determine the association between amyloid-specific biomarkers and V122I TTR carrier status; and Sub-aim 2) determine the association of amyloid-specific biomarkers with imaging-based parameters and evaluate their diagnostic utility for identifying subclinical hATTR-CA. In Aim 1, CMRI will be used to compare metrics associated with cardiac amyloid infiltration between a cohort of V122I TTR carriers without HF formed by cascade genetic testing and age-, sex-, and race-matched non-carrier controls. For Sub-Aim 1, a sub-sample of carriers and non-carrier controls enrolled in Aim 1 will undergo novel exercise CMRI to measure and compare cardiac systolic and diastolic reserve. Aim 2 involves measuring and comparing amyloid-specific biomarkers in V122I TTR carriers without HF with samples matched non-carriers (both from Aim 1) and individuals with symptomatic V122I hATTR-CA from our clinical sites. These biomarkers detect and quantify different processes of TTR amyloidogenesis and include circulating TTR, retinol binding protein 4, TTR kinetic stability, and misfolded TTR oligomers. Sub-aim 2 will establish the role of these biomarkers to detect imaging evidence of subclinical hATTR-CA disease.

Cardiac Amyloidosis Discovery Trial
Description

This is a single center, diagnostic clinical trial in which the investigators aim to prospectively validate a deep learning model that identifies patients with features suggestive of cardiac amyloidosis, including transthyretin cardiac amyloidosis (ATTR-CA). Cardiac Amyloidosis is an age-related infiltrative cardiomyopathy that causes heart failure and death that is frequently unrecognized and underdiagnosed. The investigators have developed a deep learning model that identifies patients with features of ATTR-CA and other types of cardiac amyloidosis using echocardiographic, ECG, and clinical factors. By applying this model to the population served by NewYork-Presbyterian Hospital, the investigators will identify a list of patients at highest predicted risk for having undiagnosed cardiac amyloidosis. The investigators will then invite these patients for further testing to diagnose cardiac amyloidosis. The rate of cardiac amyloidosis diagnosis of patients in this study will be compared to rate of cardiac amyloidosis diagnosis in historic controls from the following two groups: (1) patients referred for clinical cardiac amyloidosis testing at NewYork-Prebysterian Hospital and (2) patients enrolled in the Screening for Cardiac Amyloidosis With Nuclear Imaging in Minority Populations (SCAN-MP) study.

A Trial to Learn if Linvoseltamab is Safe and Works in Adults With Relapsed or Refractory Systemic Light Chain Amyloidosis (AL Amyloidosis)
Description

This study is researching an experimental drug called linvoseltamab ("study drug"). This study is focused on patients who have AL amyloidosis that has returned or have failed other therapies and need to be treated again. The study consists of 2 phases (Phase 1 and Phase 2): * In Phase 1, linvoseltamab will be given to a small number of participants to study the side effects of the study drug and to determine the recommended doses of the study drug to be given to participants in Phase 2. * In Phase 2, linvoseltamab will be given to more participants to continue to assess the side effects of the study drug and to evaluate the ability of linvoseltamab to treat AL amyloidosis. The study is looking at several other research questions, including: * How many participants treated with linvoseltamab have improvement in the abnormal proteins that cause organ problems and for how long * How many participants treated with linvoseltamab have improvement in the heart or kidney and for how long * What the right dosing regimen is for linvoseltamab * What side effects may happen from taking linvoseltamab * How much linvoseltamab is in the blood at different times * Whether the body makes antibodies against linvoseltamab (which could make the drug less effective or could lead to side effects)
