Familial Amyloid Neuropathy clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT03190577 Completed - Clinical trials for Transthyretin Amyloidosis

Assessment of the Prevalence of TTR Amyloid Neuropathy in a Population of Patients With Neuropathy of Unknown Aetiology

PRE-TRANS

Start date: September 21, 2017
Phase: N/A
Study type: Interventional

Familial amyloid neuropathy due to transthyretin gene mutations (TTR-FAP) is a rare autosomal dominant inherited disease resulting in the abnormal multi-system deposition of amyloid proteins. These deposits produce a multi-organ disease. AP is usually fatal 10 to 15 years after onset of symptoms if untreated. The prevalence of the disease remains still poorly understood and usually the search for this pathology is done in a third line of investigation. So the average time to diagnosis is extremely long, from 12 to 24 month. Now that the investigators have etiological treatment ( famidis (Vyndaqel®) and Diflunisal (Dolobid)) of this disease, it is essential to be able to detect FAP patients as early as possible. With this study, investigator decided to test for TTR mutation all patients presented with neuropathy of unknown etiology at the first line of investigation. The goal of this study is to evaluate the prevalence of FAP-TTR among neuropathy and defined the best strategy to test this population for TTR mutations.
