Frequently asked questions about Nurandociguat

What is Nurandociguat?

Nurandociguat is an investigational small molecule developed by Bayer AG for nephrology and cardiovascular indications. It is being studied in Phase 1 clinical trials in chronic kidney disease and stable coronary artery disease. It is not described as an approved therapy and remains in early clinical development.

What is Nurandociguat used for in chronic kidney disease?

Nurandociguat is being studied in chronic kidney disease to learn how a new tablet formulation is absorbed and processed in the body compared with an older tablet, and how food affects absorption of the new tablet. This work is early Phase 1 formulation and pharmacokinetic research, not a test of kidney outcomes.

Who makes Nurandociguat?

Nurandociguat is developed by Bayer AG, which trades under the ticker BAYRY. Bayer is the sponsor behind the Phase 1 studies of the drug in chronic kidney disease and stable coronary artery disease.

What phase is Nurandociguat in?

Nurandociguat is in Phase 1 clinical development. Its studies are early-stage trials focused on how the drug is absorbed and processed and on its safety when co-administered with nitroglycerin. The program has not advanced beyond Phase 1 based on the trials conducted to date.

What clinical trials is Nurandociguat in?

Nurandociguat has been studied in NCT07722585, a completed Phase 1 trial in chronic kidney disease in Germany with 16 participants comparing an old and new tablet formulation and food effects. A second Phase 1 trial, NCT07431294, is not yet recruiting and will assess nitroglycerin safety with Nurandociguat in stable coronary artery disease across Bulgaria and Germany with 36 participants.

Is Nurandociguat the same as BAY3283142?

Yes, Nurandociguat is also known as BAY3283142. The compound appears under both names, and trial listings also distinguish formulation versions such as the old tablet and new tablet, sometimes labeled SD. Searches for BAY3283142 refer to the same investigational Bayer small molecule.
