Active clinical trials for "Amyloidosis"

A Phase 1, open-label study of intravenous (IV) PRX004 as a single agent in subjects with hereditary amyloid transthyretin (hATTR) amyloidosis. The study will consist of 3 phases and will enroll up to a total of 36 subjects. A 3+3 dose escalation component to determine the safety, tolerability, PK, PD, and MTD. An expansion component in anticipated PRX004 RP2D cohorts selected from the Dose Escalation Phase. An extended dosing component for eligible subjects from the Dose Escalation or Expansion phases.

Previous studies detected that up to 15% of patients undergoing aortic valve replacement (AVR) for degenerative aortic stenosis have concomitant transthyretin amyloidosis (ATTR) cardiomyopathy (Castano, 2017). The aim of this study is to investigate the effectivity and practicability of a systematic ATTR-Screening in patients undergoing planned AVR. Moreover, we plan to develop a screening algorithm to detect ATTR in aortic stenosis (AS).

This is a single arm, open label study designed to evaluate the safety and efficacy of propylene glycol-free melphalan hydrochloride in patients with AL amyloidosis. Treatment will be comprised of propylene glycol-free melphalan hydrochloride administered intravenously at a dose of 70-100 mg/m2/day on Days -3 and -2 as conditioning prior to autologous stem cell transplantation.

The rationale for this study is to provide additional treatment with NEOD001 for subjects who complete Study NEOD001-001, and to continue to evaluate long term safety and tolerability. All subjects in the current NEOD001 trials are being dosed at 24 mg/kg, which will be continued in this study.

This phase I trial studies the side effects and best dose of pomalidomide and bortezomib when given together with dexamethasone in treating patients with amyloid light-chain amyloidosis or light chain deposition disease. Biological therapies, such as pomalidomide, may stimulate the immune system in different ways and stop abnormal cells from growing. Bortezomib may stop the growth of abnormal cells by blocking some of the enzymes needed for cell growth. Giving pomalidomide and bortezomib together with dexamethasone may be an effective treatment for amyloid light-chain amyloidosis or light chain deposition disease

Iododoxorubicin may dissolve protein deposits and be an effective treatment for primary systemic amyloidosis. Phase I trial to determine the effectiveness of iododoxorubicin in treating patients who have primary systemic amyloidosis

The primary objective of this study is to evaluate the diagnostic performance of an algorithm in identifying patients with ATTR amyloidosis.

This registry is a observational, multi-center study designed to collect data and analyze it retrospectively on patients with cardiac amyloidosis who have been evaluated and treated at major amyloid centers across the US and internationally between 1997 and 2025.

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.

The goal of the present study is to determine the occurrence of wild-type and hereditary transthyretin amyloidosis cardiomyopathy among patients with the diagnosis of idiopathic peripheral neuropathy in the setting of a state-of-the-art diagnostic work-up; the investigators believe that the identification of patients with ATTR-CM in this setting can contribute to the early diagnosis of a largely underrecognized condition and, therefore, offer conditions to timely initiation of appropriate therapy with impact on prognosis of patients.
