Frequently asked questions about Fulacimstat

What is Fulacimstat?

Fulacimstat is an investigational small molecule developed by Bayer AG under the code BAY1142524. It has been studied in clinical trials for diabetic kidney disease and for patients after acute myocardial infarction with left-ventricular dysfunction. It is not an approved medicine and remains in clinical development.

What is Fulacimstat used for in diabetic kidney disease?

Fulacimstat was studied as a treatment for patients with type II diabetes and a clinical diagnosis of diabetic kidney disease. A completed Phase 2 trial, NCT03412006, enrolled 152 patients across Bulgaria, Denmark, Finland, Israel, Italy, Spain and Sweden to investigate its efficacy, safety and tolerability.

What does Fulacimstat target?

Fulacimstat targets CMA1, also known as chymase, and acts as an inhibitor of this enzyme. CMA1 inhibition is the mechanism explored in its clinical program. The compound is a small molecule and was tested in diabetic kidney disease and after acute myocardial infarction.

Who makes Fulacimstat?

Fulacimstat is developed by Bayer AG, which trades on the OTC market under the ticker BAYRY. Bayer sponsored the clinical trials of the compound, including the Phase 2 studies in diabetic kidney disease and in patients after acute myocardial infarction with left-ventricular dysfunction.

What phase is Fulacimstat in?

Fulacimstat is in Phase 1 development overall, with completed Phase 2 studies also conducted. It is investigational and has not been approved by the FDA. The Phase 1 renal impairment study, NCT03402438, enrolled 36 healthy volunteers in Germany and has been completed.

What clinical trials is Fulacimstat in?

Fulacimstat has been evaluated in three completed trials: NCT03412006, a Phase 2 study in diabetic kidney disease with 152 patients; NCT02976467, a Phase 2 study after acute myocardial infarction with left-ventricular dysfunction with 107 patients; and NCT03402438, a Phase 1 renal impairment study with 36 healthy volunteers.

Is Fulacimstat the same as BAY1142524?

Yes, Fulacimstat is also known as BAY1142524. BAY1142524 is the Bayer development code for the same compound, and both names refer to the CMA1 inhibitor studied in diabetic kidney disease and after acute myocardial infarction. Searches for either name refer to the same investigational drug.
