Thalassemic Iron Overload Cardiomyopathy is Ameliorated by Taurine Supplementation (TICATS Study)
Hypothesis: Taurine, in combination with standard iron chelation therapy, is more effective than chelation therapy alone in reducing cardiac iron overload, oxidative stress and cardiac damage in β-Thalassemia. Protocol: Sixty subjects with transfusion dependent β-Thalassemia receiving deferasirox iron chelation therapy will be recruited and randomized in a 1:1 ratio to either (1) placebo and continuation of their iron chelation or (2) a combination of iron chelation plus taurine. Transfusion and safety visits will be scheduled monthly with clinical/biochemical assessment visits every three months. The efficacy of taurine combined with standard chelation therapy will be assessed at baseline and 12 months posttreatment by both cardiac T2\*MRI, and cardiac function. The recruitment period is projected to be 12 months from initiation.
⁃ Participants who meet all of the following criteria will qualify for entry into the study:
• Diagnosis of transfusion-dependent Thalassemia being followed at the RBC clinic at TGH
• Age 18 or older
• On a stable dose of iron chelation for \>30 days. Combination iron chelation regimen is allowed in the study
• Cardiac MRI T2\* ≥8ms measured within 3 months prior to randomization.
• Preserved left ventricular ejection fraction (LVEF) \>50% as measured by cardiac MRI measured within 3 months prior to randomization.
