Why have clinical trials in sepsis failed?

Area of Science:

• Critical care medicine
• Immunology
• Translational science

Background:

• The systemic inflammatory response is a complex biological process triggered by various factors.
• Modulating this response in sepsis has been a therapeutic target, but with limited success.
• Over 100 clinical trials have failed to produce effective treatments for sepsis.

Purpose of the Study:

• To analyze the challenges and conceptual failures in current sepsis research.
• To propose a new direction for future sepsis treatment development.

Main Methods:

• Review of over 100 randomized clinical trials on sepsis treatment.
• Analysis of the conceptual framework guiding sepsis research.
• Identification of limitations in existing research models.

Main Results:

• Despite extensive research, no significant survival improvements have been achieved through modulating the septic response.
• The current research model for sepsis is considered ineffectual.
• A need exists to abandon outdated research concepts.

Conclusions:

• Sepsis research faces a critical challenge due to a failure of concept and a reluctance to abandon ineffective models.
• Future success in developing sepsis treatments depends on large-scale clinical and biochemical epidemiology studies.
• Integrating basic and clinical science, alongside patient stratification, is crucial for targeted and effective sepsis therapies.
