A protein called glial fibrillary acidic protein (GFAP) is found at higher levels in the blood of people with familial amyloid polyneuropathy (FAP), even before symptoms appear, relative to healthy people, a study finds. Also, blood levels of a protein called neurofilament light chain (NfL) were elevated only in…
Sudoscan, a test used to indirectly assess small nerve fiber damage through sweat gland function, may be a marker of disease severity and progression in people with hereditary transthyretin (ATTRv) amyloidosis, a group of diseases that includes familial amyloid polyneuropathy (FAP). That’s according to a small study in Italy that also showed…
Family members of people with late-onset familial amyloid polyneuropathy (FAP) may face emotional and practical challenges due to the onset of disease symptoms in late adulthood, with some seeking information and support while others avoiding discussing the disease.

The U.S. Food and Drug Administration (FDA) has granted orphan drug status to ART001, a gene editing candidate that Accuredit Therapeutics is developing as a one-time treatment for transthyretin (ATTR) amyloidosis, a group of diseases that includes familial amyloid polyneuropathy (FAP). Such a designation supports developing possible treatment…
Levels of a blood protein called NfL may be useful as a marker of disease activity in people with familial amyloid polyneuropathy (FAP), a new study reports — though the utility of this biomarker may vary depending on each patient’s underlying gene mutation, according to the researchers. While the…
The U.S. Food and Drug Administration (FDA) has extended the approval of Amvuttra (vutrisiran) to adults with cardiomyopathy (heart damage) due to nonhereditary or hereditary transthyretin amyloidosis (ATTR-CM).

Wainzua (eplontersen) is now approved in the European Union (EU) for treating adults with early-stage familial amyloid polyneuropathy (FAP). With the European Commission’s approval, Wainzua can treat adults in the first two stages of FAP — stage 1, when abnormal sensations appear, but the patient is still able to…
Alnylam Pharmaceuticals is planning to launch a Phase 3 clinical trial toward the end of this year to test its therapy candidate nucresiran in people with familial amyloid polyneuropathy (FAP) — though details on the trial’s design are still being discussed with global regulators.
