Filter by:International, multicenter, observational, longitudinal study to identify biomarker/s for the development of a new MS-based biomarker for the early and sensitive diagnosis of Transthyretin-Related Familial Amyloidotic Polyneuropathy from blood and number of correctly identified patients with Transthyretin-Related Familial Amyloidotic Polyneuropathy
The primary objective for this study is to evaluate the efficacy of doxycycline + ursodeoxycholic acid (UDCA) on disease progression in Transthyretin Amyloidosis (ATTR) subjects with cardiomyopathy with or without neuropathy.
This study is being conducted to explore the potential benefits of a twelve-month doxycycline (at the best tolerated dose of 200 mg/day) and tauroursodeoxycholic acid (750 mg/day) treatment on disease progression in patients affected by transthyretin amyloidosis, including: 1) patients not eligible for liver transplantation; 2) patients eligible for liver transplantation, as a "bridge" therapy between the time of diagnosis and surgery, with the aim of stabilizing the disease; 3) patients showing disease progression after liver transplantation performed since at least 1 year. It is a phase II, therapeutic exploratory, two-part, 18-month, single centre, prospective study. Part I is a 12-month, open label treatment period in which doxycycline (200 mg/day, continuously) and tauroursodeoxycholic acid (750 mg/day continuously) are administered to 40 consenting subjects with transthyretin amyloidosis. Part II is a withdrawal period in which subjects will be monitored for disease progression. During part I, subjects will be evaluated at baseline (study Day 0), and then after 3, 6, 9 and 12 months of doxycycline plus tauroursodeoxycholic acid treatment or at premature treatment discontinuation; during part II, they will be assessed at months 15 and 18. Monthly phone contacts and blood tests will be performed to monitor potential adverse events.
THAOS is a global, multi-center, longitudinal observational survey open to all patients with transthyretin amyloidosis (ATTR), including ATTR-PN (polyneuropathy), ATTR-CM (cardiomyopathy) and wild-type ATTR-CM. It is open-ended with a minimum duration of 10 years. Patients will be followed as long as they are able to participate. The principal aims of this outcome survey are to better understand and characterize the natural history of the disease by studying a large and heterogenous patient population. Survey data may be used to develop new treatment guidelines and recommendations, and to inform and educate clinicians about the management of this disease.
