Brief summary
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.
Detailed description
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.
Interventions
AT-001 will be administered as 3 capsules twice daily, before breakfast and before dinner. At present AT001 is the sole name for the active substance. No INN/genetic name is available to date
Matching placebo will be administered as 3 capsules twice daily, before breakfast and before dinner

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Peak VO2 during cardio-pulmonary exercise test (CPET); | 15 months after randomization] | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression to overt heart failure (Stage C Heart Failure) | 27 months after randomization | 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 |
| Changes in NT-proBNP | 27 months after randomization | Changes in NT-proBNP may reflect worsening of cardiomyopathy over time |
| Changes in the modified Kansas City Cardiomyopathy Questionnaire (KCCQ) score | 27 months after randomization | Changes in the modified KCCQ may reflect deterioration of clinical status over time |
Other
| Measure | Time frame | Description |
|---|---|---|
| Worsening of diabetic cardiomyopathy | 15 and 27 months after randomization | Defined by either ≥ 20% increase in NT-proBNP or ≥ 5 point decrease in the mKCCQ score |
| Changes in echocardiographic parameters | 27 months after randomization | Changes assessed on cardiac ultra-sound from baseline |
