The prevalence of familial amyloid polyneuropathy (FAP) in Taiwan in recent years is consistent with other mid-to-high prevalence countries, but survival rates are lower than in other nations, according to a recent study. From 2008-2020, FAP prevalence, or the total number of people living with the disease, in Taiwan ranged…
Onpattro (patisiran), a liver-directed gene-silencing therapy, successfully slowed progression of symptoms that emerged in two brothers with hereditary transthyretin amyloidosis (hATTR) decades after their disease was stabilized by liver transplants, a study showed. In the reemergence of disease symptoms, the brothers showed also brain and eye problems that were…
Intellia Therapeutics is planning to launch pivotal clinical trials of its gene-editing therapy NTLA-2001 in people with familial amyloid polyneuropathy (FAP) and ATTR amyloidosis with cardiomyopathy (ATTR-CM). A pivotal trial is one where the data are expected to support an application for a therapy’s regulatory approval. Intellia is…
Amvuttra (vutrisiran) and Onpattro (patisiran) showed similar safety and efficacy for familial amyloid polyneuropathy (FAP) patients, according to new analyses from the Phase 3 HELIOS-A trial that supported Amvuttra’s regulatory approval. Both therapies led to similar reductions in transthyretin, the protein that accumulates in FAP, and they were…
Treatment with Onpattro (patisiran) or Amvuttra (vutrisiran) leads to a reduction in blood levels of neurofilament light chain (NfL), a nerve cell damage marker, among people with familial amyloid polyneuropathy (FAP), according to a new analysis of clinical trial data. Findings suggest that patients with a greater…
People with hereditary transthyretin amyloidosis (hATTR) who are treated with a combination of therapies appear to have better health outcomes than those given only one type of medication. That’s according to new findings presented at the 75th American Academy of Neurology (AAN) annual meeting, being held April 22-27 in Boston…
Changes in the nerve fibers of the cornea — the eye’s clear protective outer layer — may help in the early diagnosis of hereditary transthyretin amyloidosis (hATTR), a group of disorders that includes familial amyloid polyneuropathy (FAP), a study shows. A noninvasive imaging method, called corneal confocal microscopy (CCM), identified…
In the U.S., one-third of people with hereditary transthyretin amyloidosis (hATTR) — a group of disorders that includes familial amyloid polyneuropathy (FAP) — are diagnosed with carpal tunnel syndrome years before a hATTR diagnosis, a study indicated. This finding suggests that a history of carpal tunnel, a condition that affects…
More than one year of treatment with eplontersen safely reduced symptoms of nerve damage and improved quality of life for adults with familial amyloid polyneuropathy (FAP), according to top-line data from the Phase 3 NEURO-TTRansform trial. The experimental therapy from Ionis Pharmaceuticals and AstraZeneca also significantly…
Tegsedi (inotersen) slows the progression of symptoms, particularly muscle weakness and sensation loss, in people with familial amyloid polyneuropathy (FAP), according to a post-hoc analysis of the Phase 3 NEURO-TTR trial. “These results support previous evidence demonstrating the efficacy of [Tegsedi] in this patient population,” its researchers wrote. Post-hoc analyses…
