Blood pressure drug study in septic shock halted early
NCT ID NCT06426407
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This observational study aimed to understand why some septic shock patients respond better to the drug vasopressin. Researchers planned to compare blood markers, heart ultrasound images, and tissue oxygen levels between responders and non-responders. However, the study was terminated after enrolling only 2 participants, so no meaningful conclusions can be drawn.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vasopressin
- What this could lead to
- If successful, this could help doctors identify which septic shock patients benefit most from vasopressin, potentially leading to more personalized treatment.
- What could go wrong
- The study was terminated early with only 2 participants, so results are very limited and may not be reliable or generalizable.

Who is studied
Adult patients with septic shock are eligible for this study. Patients ordered vasopressin as an adjunct to norepinephrine as part of routine care comprise the primary cohort of interest. An active control cohort of patients who are only receiving norepinephrine will also be enrolled.

Inclusion Criteria: * Adult patients (≥18 years old) * Septic shock (as defined by Sepsis-3) * Receiving norepinephrine * Admitted to a medical, surgical, NeuroSciences, or mixed intensive care unit * Central venous catheter in place * Ordered fixed-dose vasopressin as an adjunct to norepinephrine by the primary care team (unless in active control cohort) Exclusion Criteria: * Vasopressin ordered for an indication other than septic shock * Vasopressin initiated at another institution * Receiving a primary vasopressor other than norepinephrine (eg, phenylephrine) * Positive test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within the preceding 28 days * Blood hemoglobin concentration \<7 g/dL * Primary treatment team determines that vasopressin initiation is emergent * Patient or their legal authorized representative opts to not participate in the study
