|Familial ATTR-CM (ATTRm-CM, or FAC) and Wild-type ATTR-CM (ATTRwt-CM)||Drug: AG10 Drug: Placebo Oral Tablet||Phase 2|
A Phase 2, Randomized, Placebo-controlled, Dose-ranging Study of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of AG10 in Patients with Symptomatic Transthyretin Amyloid Cardiomyopathy.
The primary objective of this study is to evaluate the safety and tolerability of AG10 administered to adult patients with symptomatic transthyretin amyloid cardiomyopathy (ATTRCM).
This study will be a Phase 2, randomized, placebo-controlled, dose-ranging study in 45 male and/or female patients with symptomatic ATTR-CM aged 18 through 90 years.
If all doses are well tolerated, the duration of each patient's participation in the study will be 28 days of treatment. In addition, there will be a 28-day screening period before treatment and a 30-day follow-up period before the final Follow-up Visit.
This prospective, randomized, multicenter, double-blind, parallel group, placebo-controlled, dose-ranging study will evaluate the safety, tolerability, PK and PD of AG10 compared to placebo administered on a background of stable heart failure therapy. Screening and randomization will be followed by a 28-day blinded, placebo-controlled treatment period. secondary objectives of this study are: to characterize the pharmacokinetics (PK) of AG10 administered orally twice daily in patients with symptomatic ATTRCM, and to describe the pharmacodynamic (PD) properties of AG10 as assessed by established assays of transthyretin (TTR) stabilization, including Fluorescent Probe Exclusion (FPE) assay and Western blot, and to describe the PKPD relationship of AG10 in adult patients with symptomatic ATTRCM.
Eligible patients will be randomized in a 1:1:1 ratio to placebo or one of two different doses of AG10 administered twice daily. A minimum of 30% of patients enrolled will be mutant ATTR-CM.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||49 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||A randomized, doubleblind, placebo-controlled, dose-ranging design is considered to be the most appropriate study design for meeting this objective. On the basis of information gained from previous clinical experience with AG10, the doses used in this study will be selected to determine the dose with the better safety and tolerability profile.|
