Information provided by (Responsible Party):
Rodney H. Falk, MD, Brigham and Women's Hospital
  Purpose
The objective of the study is to determine whether the combination of the bile acid TUDCA, and doxycycline will slow the progression of familial and senile amyloidosis.

Condition Intervention Phase
Amyloidosis; Heart (Manifestation) Senile Cardiac Amyloidosis Drug: Tauroursodeoxycholic Acid and Doxycycline Phase 1 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An 18 Month, Open Label Study of the Tolerability and Efficacy of a Combination of Doxycycline and Tauroursodeoxycholic Acid (TUDCA) in Patients With Transthyretin Amyloid Cardiomyopathy.

Further study details as provided by Rodney H. Falk, MD, Brigham and Women's Hospital:

Primary Outcome Measures:
  • The rate of progression of transthyretin cardiac amyloidosis, as measured by changes in strain echocardiography, in a group of patients taking a combination of doxycycline and TUDCA. [ Time Frame: Time Frame: * (FDAAA) outcome measure is assessed every 6 months by serial echocardiography, with final measurement 18 months after enrollment. ]
    Outcome measure, namely changes in longitudinal echocardiographic strain, will be compared to previously determined changes derived from a cohort of patients with TTR cardiac amyloidosis who were not receiving specific therapy for amyloid deposition.


Secondary Outcome Measures:
  • Number of patients with adverse events to the medications over the period of therapy (18 months) [ Time Frame: 18 months ]
    Measurements of kidney function (BUN and creatinine) and blood counts will be done every 3 months.

  • To evaluate general and health related quality of life (QoL) in SSA and ATTR subjects. [ Time Frame: Measurements made every 6 months for 18 months. ]

Enrollment: 38
Actual Study Start Date: June 2013
Study Completion Date: May 31, 2015
Primary Completion Date: May 31, 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TUDCA and Doxycycline
TUDCA taken orally, 250 mg three times daily. Doxycycline taken orally, 100 mg twice daily
Drug: Tauroursodeoxycholic Acid and Doxycycline
