Bayer Maps Sepsis-Related Clotting Risks in Japan, Sharpening Its Critical Care Strategy

Bayer AG (BAYRY) announced an update on their ongoing clinical study.

Study Overview

Bayer is running a hospital-based cohort study in Japan titled “A Study for the Disseminated Intravascular Coagulation Among Patients With Sepsis in Japan: A Hospital-based Cohort Study.” The goal is to understand how often adults with sepsis develop disseminated intravascular coagulation (DIC), a dangerous blood clotting problem, and how these cases are treated and managed in routine care. Using existing hospital data, the study looks at patterns of DIC in sepsis, thrombocytopenic sepsis, and septic shock, giving Bayer and the market better insight into real-world disease burden in a country where DIC drugs are already approved.

Intervention/Treatment

This is an observational study only. There is no new drug or procedure being tested. Researchers are reviewing existing records from seven Japanese hospitals, focusing on current treatments used for sepsis and DIC in everyday practice. The aim is to map how patients are treated today, not to change therapy, which allows Bayer to better understand how its present and future products may fit into real-world care.

Study Design

The study is observational, retrospective, and cohort-based. That means the team looks back at past patient records rather than assigning any new treatments. Patients are grouped into cohorts: those with sepsis, those with sepsis-related DIC, and those with DIC without sepsis. There is no randomization, no blinding, and no control versus active treatment groups, since the main purpose is to describe what happens in normal hospital practice and how often DIC occurs in different sepsis situations.

Study Timeline

The hospital data cover the period from June 2018 to June 2023, giving a five-year snapshot of sepsis and DIC care in Japan. The study was first submitted on March 25, 2024, signaling Bayer’s formal move to analyze and disclose these data. The overall study status is listed as completed, meaning data collection and primary analysis are finished. The record was last updated on January 20, 2026, which is important for investors because it confirms that the dataset and interpretations are current and may soon feed into publications, guideline discussions, or internal pipeline planning.

Market Implications

While no new medicine is being tested, this update is still relevant for Bayer shareholders. A stronger understanding of DIC in sepsis can help Bayer size the market for clotting and sepsis-related therapies, refine trial design for future drugs, and support health economic arguments in Japan, where DIC medicines are already part of standard care. Better real-world data can also help defend or expand the use of existing agents and support pricing talks with payers. For investors, this work points to a deliberate build-out of Bayer’s position in critical care and thrombosis, an area that also involves competitors with anticoagulants and sepsis-related products. Any future pipeline moves or label-expansion trials informed by this dataset could improve long-term revenue visibility, even if the immediate share price impact of this update alone is likely modest.

The study is completed and has been recently updated, with further details available on the ClinicalTrials portal.
