Official title

CSP #526 - A Thyroid Hormone Analog to Fight Heart Failure: Phase II Trial (DITPA)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Congestive heart failure (CHF) affects 4-5 million Americans, and its prevalence is predicted to increase over the next few decades. Thyroid hormone has unique actions which make it a novel and potentially useful agent for treatment of CHF. Due to possible adverse affects of thyroid hormone, there is interest in developing analogs with fewer undesirable side effects. 3,5- diiodothyropropionic acid (DITPA) has been shown to improve diastolic function in both animal models and a recently completed double-blind placebo controlled trial in 19 humans. The goal of the proposed Phase II study is to show safety and demonstrate a medication of efficacy of DITPA needed in patients with CHF. This study is a prerequisite for a larger Phase III trial which would determine whether mortality is improved with DITPA. To better define the appropriate doses, prior to the Phase II study we will conduct an initial pharmacokinetic study.
