Study Summary

This trial is testing whether the thyroid hormone T3 is safe and effective in treating heart failure. Participants will be randomly assigned to either receive the hormone or not, and then monitored for a year. If successful, this could result in a new treatment for heart failure.

Who is the study for?
This trial is for adults aged 18-80 with ischemic heart failure and a left ventricular ejection fraction (LVEF) ≤ 40%. They must be stable, on standard heart failure therapies including metoprolol succinate, and have an ICD or CRT-D device. Excluded are those with recent cardiac events, other drug trials within 3 months, endocrine disorders like thyroid disease, severe blood pressure issues, liver or kidney dysfunction, severe neurological disorders, life-limiting cancer history or planning major surgery.Check my eligibility
What is being tested?
The study tests if Triiodothyronine (T3), a thyroid hormone can safely improve symptoms of ischemic heart failure. Participants have equal chances to receive T3 or no treatment initially; non-treated in Phase 1 may get T3 in Phase 2. The first group stays at the GCRC for monitoring over five days plus follow-ups; the second has outpatient visits.See study design
What are the potential side effects?
Potential side effects of T3 treatment could include abnormal heart rhythms due to hormonal changes affecting the cardiovascular system. Other general side effects might involve alterations in metabolism leading to weight changes, temperature sensitivity issues and potential impact on mood.

Trial Design

4Treatment groups
Experimental Treatment
Placebo Group
Group I: Experimental Phase IIExperimental Treatment1 Intervention
Patients who were enrolled in the open-label control group of Phase I and who have completed the 3-month follow-up will be permitted to enroll in Phase II. This Phase will start treatment after completion of Phase I and approval from the Data and Safety Monitoring Board (DSMB) to proceed with a single cohort that will receive a stable dose of the study drug (20 µg T3 orally twice daily for 5 days).
Group II: Experimental Phase IBExperimental Treatment1 Intervention
In Phase IB, dose adjustments will be calculated while accounting for laboratory and safety data from the first two participants (Phase IA) for the remaining 3 participants within the treatment arm of Phase I. Participants 3 to 5 will receive 10 µg T3 orally twice daily on day 1 and 20 µg T3 twice daily from day 2 to 5.
Group III: Experimental Phase IAExperimental Treatment1 Intervention
In Phase IA two participants (1 and 2) will receive ascending dose levels of the study drug (5 µg T3 orally twice daily for the first 2 days and 10 µg T3 orally twice daily for the next 3 days).
Group IV: Control Group-Phase IA and IBPlacebo Group1 Intervention
The control group will have testing as the experimental group but will not be given any medications.
