FDA Approves Onpattro (patisiran) Targeted RNA-based Therapy for Polyneuropathy Caused by hATTR

August 10, 2018 -- The U.S. Food and Drug Administration today approved Onpattro (patisiran) infusion for the treatment of peripheral nerve disease (polyneuropathy) caused by hereditary transthyretin-mediated amyloidosis (hATTR) in adult patients....

Authors: N M, Soni P, Anand R, Bali S, Hari Abstract Amyloidosis is a conglomeration of diseases due to production and deposition of amyloid, a proteinaceous substance, into organs, tissues, nerves and other places in the body affecting their normal function. This case report is of a 65 year old gentleman, resident of Bihar admitted with a short history of two months. He came with chief complaints of swelling in both lower limbs associated with heaviness in legs, shortness of breath, dizziness, fatigue and passage of frothy urine for two months. He was investigated and found to have proteinuria, low voltage ECG, Ec...

Contributors : Richard M Giadone ; George J Murphy ; Taylor M MatteSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensThe systemic amyloidoses are diverse disorders in which misfolded proteins are secreted by effector organs and deposited as proteotoxic aggregates at downstream tissues. Although well-described clinically, the contribution of synthesizing organs to amyloid disease pathogenesis is unknown. Here, we utilize hereditary transthyretin amyloidosis (ATTR amyloidosis) induced pluripotent stem cells (iPSCs) to define the contribution of HLCs to the proteotoxicity of secreted TTR. ...

Transthyretin and light-chain amyloidosis are the 2 main causes of cardiac amyloidosis. Recent developments in molecular imaging have transformed our ability to diagnose transthyretin cardiac amyloidosis noninvasively and unmasked a hitherto unrecognized prevalence of the disease. This review summarizes the current and evolving imaging approaches, their molecular structural basis, and the gaps in imaging capabilities that have arisen as a result of parallel developments in pharmacotherapy delivering the first effective treatment options for this condition.

Conclusion: 11C-metoclopramide can measure ABCB1 induction in the mouse brain without the need to consider an arterial input function and may find potential application in Alzheimer disease patients to noninvasively evaluate strategies to enhance the clearance properties of the BBB.

a Stoppacciaro Monoclonal Gammopathies of Renal Significance (MGRS) are a rather heterogeneous group of renal disorders caused by a circulating monoclonal (MC) immunoglobulin (Ig) component, often in the absence of multiple myeloma (MM) or another clinically relevant lymphoproliferative disorder. Nevertheless, substantial kidney damage could occur, despite the “benign” features of the bone-marrow biopsy. One example is renal amyloidosis, often linked to a small clone of plasma cells, without the invasive features of MM. However, patients with amyloidosis may present with a nephrotic syndrome and ren...

We sought to study the clinical characteristics and prognosis of both diseases. METHODS: We conducted a single-centre, retrospective review of all patients di...

Abstract Vutrisiran (ALN-TTRsc02) is a liver-directed, investigational, small interfering ribonucleic acid drug for the treatment of transthyretin (TTR)-mediated amyloidosis. This Phase 1, randomized, single-blind, placebo-controlled, single ascending dose study evaluated the pharmacodynamics, pharmacokinetics, and safety profile of subcutaneously-administered vutrisiran (5-300 mg) in healthy subjects (n = 80). Vutrisiran treatment achieved potent and sustained TTR reduction in a dose-dependent manner, with mean maximum TTR reduction of 57-97%, maintained for ≥90 days post-dose. Vutrisiran was rapidly absorbed ...
