What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study follows 300 adults in intensive care with septic shock to track how their immune systems change over time. Researchers will analyze blood samples taken alongside routine care to measure different types of immune cells. The goal is to understand why some patients develop long-lasting immune suppression, which can lead to secondary infections and worse outcomes. This knowledge could help identify patients who might benefit from future immune-stimulating treatments.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could point toward new ways to identify which septic shock patients might benefit from immune-boosting therapies.
What could go wrong
This is an observational study, not a treatment trial. It may reveal patterns but cannot prove that any intervention improves outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Men or women aged 18 years or over * Hospitalised patients with septic shock that began less than 48 hours prior to screening, defined by: * the presence of a diagnosed or suspected site of infection requiring microbiological sampling * the need for vasopressor therapy to maintain a mean arterial pressure ≥ 65 mm Hg * hyperlactataemia \> 2 mmol/L (18 mg/dL) within 24 hours of the start of vasopressor therapy despite adequate fluid resuscitation (30 ml/kg). * A patient or relative who has been informed of the study protocol and has not objected to participating in the study Exclusion Criteria: * Pregnant or breastfeeding women * People not covered by a social security scheme or similar scheme * Adults subject to legal guardianship (guardianship, curatorship) * Patients with a language barrier * Persons deprived of their liberty by a judicial or administrative decision * Subjects participating in another interventional research study involving an exclusion period that is still ongoing at the time of pre-inclusion and which, in the investigator's judgement, may interfere with this study
