Emulation of the STEP-HFpEF DM Heart Failure Trial in Healthcare Claims Data

Completed · Has a placebo group

Conditions studied: Diabetes Mellitus, Type 2, HFpEF - Heart Failure With Preserved Ejection Fraction

In brief

Investigators are building an empirical evidence base for real-world data through large-scale emulation of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.

LV hypertrophy with septal thickness or posterior wall thickness ≥1.2cm
• Hospitalization with a primary diagnosis of decompensated heart failure which required intravenous loop diuretic treatment, within the previous 12 months in combination with at least two of the following (documented by echocardiography within 12 months prior to or at screening): i. Septal é < 7cm/sec or lateral é < 10cm/sec or average E/é ≥15 ii. PA systolic pressure >35mmHg iii.

• Diagnosed with T2D ≥ 90 days prior to the day of screening.
• Subject treated with diet, exercise, and/or antidiabetic treatment* according to local label in stable dosing for at least 30 days prior to screening: o *OAD(s): unchanged drug(s), dose and dosing frequency o *Insulin(s): unchanged regimen (basal, basal + bolus, premix combination) with stable total daily insulin dose as judged by the investigator

You may not qualify if…

• Myocardial infarction, stroke, hospitalization for heart failure, unstable angina pectoris or transient ischemic attack within 30 days prior to the day of screening.
• Systolic blood pressure > 160 mmHg at screening.
• Any other condition judged by the investigator to be the primary cause of dyspnea (such as heart failure due to restrictive cardiomyopathy or infiltrative conditions (e.g. amyloidosis), hypertrophic obstructive cardiomyopathy, primary pulmonary arterial hypertension, chronic obstructive pulmonary disease, right heart failure due to pulmonary disease, complex congenital heart disease, anemia, or more than moderate heart valve disease).
• Bariatric surgery prior to screening or planned bariatric surgery within the trial time course.
• History of type 1 diabetes (history of gestational diabetes is allowed).
• Treatment with any GLP-1 receptor agonist within 90 days prior to the day of screening.
• Uncontrolled and potentially unstable diabetic retinopathy or maculopathy.

• Female who is pregnant, breast-feeding or intends to become pregnant or is of child-bearing potential and not using a highly effective contraceptive method.
• Any disorder, including severe psychiatric disorder, suicidal behavior within 90 days before screening, and suspected drug abuse, which in the investigator´s opinion might jeopardize subject´s safety or compliance with the protocol.
