Transthyretin Amyloidosis Clinical Trial
Official title:
A Single Center, Twelve-month, Open-label, Prospective Study Followed by a Six-month Withdrawal Period to Evaluate the Efficacy, Tolerability, Safety and Pharmacokinetics of Doxycycline in Combination With Tauroursodeoxycholic Acid in Transthyretin Amyloidosis
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.
