Canagliflozin Targeting Vascular Inflammation

Официальное название

Canagliflozin Targeting Vascular Inflammation: An Ottawa Imaging Study - A Pilot Study

Обзор

CANTOR SING is a pilot single center double blinded randomized study. The investigators will compare the effect of canagliflozin (300 mg daily - intervention arm) vs. placebo (control group) on the FDG aortic uptake in patients with stable CAD (over 60 days post-myocardial infarction) after a 6-month period of treatment. The investigators plan to enroll 8 patients in each arm (total sample size: 16 patients). Primary endpoint is the change in FDG aortic uptake between baseline and 6 months in each arm.

Подробное описание

CANTOR SING is a pilot single center double blinded randomized study to determine the effect of targeted anti-inflammation therapy using canagliflozin, on aortic inflammation using imaging, i.e. ascending aortic FDG uptake. The current proposal uses a randomized design to evaluate the effect of canagliflozin vs. placebo on aortic inflammation activity over 6 months measured using FDG PET.

At the University of Ottawa Heart Institute (UOHI) patients with diabetes and stable CAD (defined as patients over 60 days post-myocardial infarction) will be recruited.

Patients who meet inclusion/exclusion criteria will undergo clinical evaluation, FDG PET imaging with contrast-CT, and blood sample collection. HbA1C, Fasting Blood Sugar (FBS), lipids, C-reactive protein (CRP), creatinine (CR), glomerular filtration rate (GFR), complete blood count (CBC), hemoglobin, liver function tests - AST, ALT, creatine kinase (CK) will be collected from the patient's clinical data or if not available may be collected as part of the study.

Patients recruited into the CANTOR SING study will be randomized to receive either an oral canagliflozin 300 mg capsule or placebo capsule administered once daily for 6 months. Patients will take the medication for 6 months. The study will be conducted in a double-blinded fashion.

Patients will be followed up every 3 months for the 6-month evaluation period. Clinical evaluation and blood collection for labs (CBC, electrolytes, CPK, ALT, AST, creatinine) will performed at baseline and will be repeated every 3 months for a a total of 6 months of follow-up. FDG PET imaging with contrast-CT will be repeated at 6 months. Finally, blood will be collected at baseline and 6 months.
