2 Clinical Trials for Various Conditions
Non-ischemic cardiomyopathy and heart failure are highly influenced by the presence of systemic inflammation. Doxycycline is a FDA-approved drug to treat bacterial infections which also shows powerful anti-inflammatory effects. In this study we plan to determine the effects of Doxycycline in patients with stable heart failure and non-ischemic cardiomyopathy on peak of aerobic exercise capacity (peak V02) and ventilator efficiency measured with a cardiopulmonary test.
The proposed study is a sub-study of the CANTOS trial (A randomized, double-blind, placebo-controlled, event driven trial of quarterly subcutaneous canakinumab in the prevention of recurrent cardiovascular events among stable post-myocardial infarction patients with elevated high sensitivity C-reaction protein (hsCRP) \[CACZ885M2301\]). The study proposes to perform serial Cardiopulmonary Exercise Tests (CPX) to prospectively measure changes in aerobic exercise capacity in patients with prior myocardial infarction (MI), elevated C reactive protein plasma levels, and symptomatic heart failure with reduced systolic function, who are enrolled in the main CANTOS trial and are randomly assigned to Canakinumab (3 different doses) or Placebo. The subjects enrolled in this substudy will undergo repeated CPX and echocardiograms over the first 12 months of the CANTOS trial. The subjects will received the experimental treatment as randomized in the main CANTOS trial and they will not receive any additional experimental treatment as part of the sub-study. This study is a an Investigator-initiated (Dr. Abbate) single-center (Virginia Commonwealth University) sub-study of the CANTOS trial, supported by Novartis pharmaceuticals.
