AT-02, to clear amyloid deposits, named orphan drug by FDA

The U.S. Food and Drug Administration (FDA) has given orphan drug designation to AT-02, Attralus’ investigational candidate for the treatment of transthyretin amyloidosis (ATTR), a group of diseases that includes familial amyloid polyneuropathy (FAP). Orphan drug status supports the development of potential treatments for rare diseases, those…

FAP therapy Amvuttra closer to reimbursement in Canada

Adults with familial amyloid polyneuropathy (FAP) living in Canada may soon be able to receive Amvuttra (vutisiran) at little or no cost through public drug plans, the therapy’s developer said. Amvuttra is approved in the country for adult FAP patients with stage 1 or stage 2 polyneuropathy or…

Eplontersen approved in UK for FAP; recommended for EU approval

The Medicines and Healthcare products Regulatory Agency (MHRA) in the U.K. has approved the injection therapy eplontersen — under the brand name Wainzua — for treating adults with familial amyloid polyneuropathy (FAP). Additionally, a European Union regulatory committee has recommended the treatment’s approval in the EU for adults…

Green tracer may detect ATTR protein deposits at routine eye exam

Applying a fluorescent green tracer called AMDX-9101 during a routine eye exam may enable the detection of the toxic transthyretin protein deposits that cause symptoms of transthyretin amyloidosis (ATTR), a group of conditions that include familial amyloid polyneuropathy (FAP). It’s too early to know if the approach would work…

TTR gene mutation, unique to China, tied to eye condition, neuropathy

Gly103Arg, a mutation in the TTR gene that has been exclusively reported in Chinese people, is associated with a familial amyloid polyneuropathy-like profile marked by eye and neurological involvement, according to a case report and literature review study. All three patients from a single family carrying the mutation had…

Noninvasive eye test can help diagnose hATTR at early stage

People with hereditary transthyretin amyloidosis (hATTR), a group of diseases that includes familial amyloid polyneuropathy (FAP), have significantly shorter nerve fibers in their corneas, the eye’s outermost layer, relative to healthy people, a study showed. Shorter corneal nerve fibers could be detected using a noninvasive technique known as corneal…

Excess blood acid from kidney problem common in hATTR: Study

Nearly every fifth adult with hereditary transthyretin amyloidosis (hATTR), a group of conditions that includes familial amyloid polyneuropathy (FAP), has renal tubular acidosis (RTA) — a problem that occurs when the kidneys fail to remove acids from the blood into the urine. That’s according to a new study from…

2 proteins may be familial amyloid polyneuropathy biomarkers

People with familial amyloid polyneuropathy (FAP) and other forms of hereditary transthyretin amyloidosis (hATTR) have abnormal blood levels of two proteins, called growth differentiation factor-15 (GDF-15) and uromodulin (Umod), a small study reports. The preliminary findings from 16 patients in Italy suggest GDF-15 and Umod may serve as biomarkers of…
