Frequently asked questions about BAY 3389934

What is BAY 3389934?

BAY 3389934 is an investigational small molecule developed by Bayer AG for sepsis and sepsis associated disseminated intravascular coagulation (DIC). It is in Phase 1 clinical development and has not been approved. The program includes a completed Phase 1 study in healthy Japanese volunteers and a recruiting Phase 1 study in patients with sepsis induced coagulopathy.

What is BAY 3389934 used for in sepsis associated disseminated intravascular coagulation (DIC)?

BAY 3389934 is being studied for sepsis and sepsis associated disseminated intravascular coagulation (DIC), conditions in which abnormal blood clotting accompanies severe infection. It remains investigational and is not approved for any use. Clinical testing so far has focused on safety, tolerability, and dose selection rather than confirmed efficacy.

Who makes BAY 3389934?

Bayer AG develops BAY 3389934. Bayer trades on the OTC market under the ticker BAYRY. The company is running the Phase 1 program for this small molecule in sepsis and sepsis associated disseminated intravascular coagulation (DIC), with studies conducted in Japan, the United States, Belgium, France, Germany, and the Netherlands.

What phase is BAY 3389934 in?

BAY 3389934 is in Phase 1 clinical development. One Phase 1 trial has been completed and one Phase 1 trial is currently recruiting. The drug is investigational and has not received FDA approval. The completed study enrolled 16 healthy Japanese volunteers, and the recruiting study plans to enroll 36 participants.

What clinical trials is BAY 3389934 in?

BAY 3389934 has two Phase 1 trials. NCT07176728, completed, assessed safety and dose effects in 16 healthy Japanese volunteers and enrolled in Japan. NCT06854640 is recruiting 36 adults with sepsis induced coagulopathy across the United States, Belgium, France, Germany, and the Netherlands. Both trials require participants aged 18 years or older.

Is BAY 3389934 the same as BAY3389934?

Yes, BAY 3389934 and BAY3389934 refer to the same investigational compound from Bayer AG. The spelling without a space is a common alternate form used in study records and search queries. Both names identify the same Phase 1 small molecule being studied in sepsis and sepsis associated disseminated intravascular coagulation (DIC).
