Assessing the Efficacy of Dapagliflozin as a Vasculoprotective Treatment in Septic Shock Patients With Microcirculatory Dysfunction (GLIFLOSHOCK)

March 23, 2026 updated by: University Hospital, Strasbourg, France

Microcirculatory dysfunction is a key driver of organ failure and mortality in septic shock, characterized by endothelial injury and impaired vasoregulation. Despite its strong prognostic value, it remains unaddressed by current therapies. SGLT-2 inhibitors (SGLT-2i) have shown promising vasculoprotective, anti-inflammatory, and glucose-lowering effects that may help restore endothelial function, reduce vascular leakage, and manage stress-induced hyperglycemia-factors central to septic shock pathophysiology. Preclinical and clinical observational studies suggest potential benefits, but clinical research in this specific context is lacking. This trial aims to evaluate the efficacy and safety of SGLT-2i in septic shock patients with clinical signs of microcirculatory failure, addressing a critical unmet medical need.

Septic shock management relies on rapid infection control, hemodynamic stabilization with fluids and vasopressors, and supportive care, with corticosteroids used in select cases. However, this standardized approach faces major limitations due to patient heterogeneity, treatment-related complications (e.g., fluid overload, vasopressor side effects), and rising antimicrobial resistance. Adjunctive therapies have largely failed to improve outcomes, reflecting the complex pathophysiology of septic shock. These challenges highlight a pressing need for novel, targeted interventions and a shift toward personalized treatment strategies.

The investigators hypothesize that early administration of SGLT-2 inhibitors within 14 hours of septic shock onset in patients showing signs of microcirculatory dysfunction will improve 28-day outcomes mainly by targeting endothelial and microvascular injury. Expected benefits include reduced mortality and organ dysfunction, faster recovery with lower resource use, a favorable safety profile, and potential for global implementation as a cost-effective adjunctive therapy.

This study will be a multicenter, prospective, randomized, and comparative double-blind trial. All patients admitted with septic shock in the ICU will be screened for trial eligibility criteria.

After verifying the eligibility criteria and obtaining patient or family consent, or after an emergency inclusion procedure, eligible patients will be randomized in a 1:1 ratio to receive either Dapagliflozin (10 mg once daily) or matching placebo in addition to standard-of-care.

Patients will be followed up for 1 year or until death, whichever occurs first.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No
