Can a blood protein flag sepsis before it strikes?
NCT ID NCT07813767
First seen Sep 10, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
Researchers are testing whether a protein called Pancreatic Stone Protein (PSP) can identify emergency room patients with infection who are at risk of developing sepsis. Adults with suspected infection receive either a single dose of the antibiotic meropenem or a placebo. The trial tracks survival and organ function over 28 and 90 days to see if early treatment helps.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- meropenem, an antibiotic given as an infusion
- What this could lead to
- If it works, this could give emergency doctors a fast blood test to spot sepsis risk and a way to treat it before organs are damaged.
- What could go wrong
- Sepsis is complex and a single early antibiotic dose may not stop it. The trial may show no benefit, and antibiotics carry risks like allergic reactions and resistant infections.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Written informed consent * Adult (≥18 years) patients of both sexes * Infection suspicion defined as the presence of at least one of: i) fever ≥38°C; ii) tachycardia (\>90 beats/min); iii) acute presence of shortness of breath or dysuria, or diarrhea or abdominal pain; and iv) complaints that according to investigator's discretion indicate/are correlated with the presence of infection * Presence of only one of qSOFA signs (mental confusion, systolic blood pressure less than 100mmHg, respiratory rate more than 22 breaths/min) OR NEWS2 equal to 5 or 6. It is explicitly stated that patients with 0 qSOFA signs may be enrolled in the study if the NEWS2 is 5 or 6. It is also explicitly stated that patients with NEWS2 less than 5 may be enrolled in the study if qSOFA is equal to one. * PSP ≥300 ng/ml measured at the Triage Exclusion Criteria: * Deny to consent * Age less than 18 years * Presence of nil, two or three signs of qSOFA * NEWS2 ≥7 * Full-blown sepsis with overt organ dysfunction (defined as need of high flow oxygen or mechanical ventilation or vasopressors) * Pregnancy (pregnancy test either blood or uninary will be conducted at the ED for female patients of reproductive age) or lactation * Hypersensitivity to meropenem, or to any other antibacterial agent that includes meropenem. Severe hypersensitivity to any antibacterial agent belonging to beta lactam class (eg. penicillins or cephalosporins). * Patients receiving probenecid, valproic acid or warfarin. * Documented acute organ dysfunction compatible with sepsis, as reflected by an increase in SOFA-2 score by ≥2 points.
