This is a multicenter, randomized, placebo-controlled, 2-part study to evaluate the safety and efficacy of AT-001 in adult patients (N=675) with Diabetic Cardiomyopathy at high risk of progression to overt heart failure.
The study consists of two consecutive parts: Part A and Part B. Part A will evaluate the safety and efficacy of two doses of AT-001 vs placebo. The primary objective of Part A is to demonstrate that AT-001 improves or prevents the decline of functional capacity in patients with Diabetic Cardiomyopathy. Part B is an extension of at least 12 months that will evaluate the safety and efficacy of chronic administration of AT-001 vs placebo in the same patients who had previously been evaluated in Part A. Assessments in Part B will include safety endpoints and exploratory clinical efficacy endpoints, i.e. death and hospitalization due to a cardiac event.

Peak VO2 during cardio-pulmonary exercise test (CPET);
Changes in Peak VO2 during cardio-pulmonary exercise test (CPET) from baseline to approximately Month 15 (15-18 months). A CPET may be repeated at approximately Month 27 (27-30 months).
Time frame: 15 months after randomization]
Progression to overt heart failure (Stage C Heart Failure)
Defined by the occurrence of one of the following events: cardiovascular death, hospitalization for heart failure, urgent heart failure visit, new diagnosis of heart failure
Time frame: 27 months after randomization
Changes in NT-proBNP
Changes in NT-proBNP may reflect worsening of cardiomyopathy over time
Time frame: 27 months after randomization
Changes in the modified Kansas City Cardiomyopathy Questionnaire (KCCQ) score
Changes in the modified KCCQ may reflect deterioration of clinical status over time
Time frame: 27 months after randomization
