IMPROVE-DiCE: Study to Evaluate Effect of IMB-1018972 on Cardiac Energetics in T2DM & Obesity (Pt 1) With HFpEF (Pt 2)

June 25, 2025 updated by: Imbria Pharmaceuticals, Inc.

A Pharmacodynamic Study to Evaluate the Effects of IMB-1018972 on Myocardial Energetics, Metabolism, and Function in Patients With Type 2 Diabetes.

The purpose of this study is to assess the activity of IMB-1018972 on cardiac energetic reserve at rest and during stress and to assess safety and tolerability

Time Frame: Baseline, End of Treatment (up to 16 weeks)
Baseline, End of Treatment (up to 16 weeks)
Change in cardiac PCr/ATP ratio with dobutamine stress (Stage 1 only) measured by 31P-MRS at baseline and at EOT with 200 mg BID of IMB-1018972
Time Frame: Baseline, End of Treatment (up to 8 weeks)
Baseline, End of Treatment (up to 8 weeks)

Secondary Outcome Measures

Outcome Measure
Time Frame
