What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is collecting blood samples from 300 cancer patients to look for immune cells that target tumors. Researchers want to understand how the immune system responds to cancer and treatments. The study does not test a new drug or therapy, but aims to gather knowledge that could help future research.

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 help researchers better understand how the immune system fights cancer, potentially guiding future treatments.
What could go wrong
This is an observational study, not a treatment trial. It is early-stage research and may not lead directly to new therapies.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 300 people

The number the study aims to enrol. It can still change while the study runs.

Started

Aug 2022

Expected to finish

Sep 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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

Inclusion Criteria: 1. Patient aged 18 or over, 2. Patient presenting an invasive tumor pathology (proven or suspected). The location and / or stage of which are defined for each cohort through an amendment to the protocol, 3. Patient treated with immune-modulators or other treatments likely to modify immunological parameters, 4. Suspicion of immune mediated response or toxicities (assessed by the immunologists), 5. Peripheral venous capital usable and compatible with the realization of 2 venous accesses for lymphapheresis and absence of cardiovascular problem (heart failure, arrhythmia ...), per investigator assessement, 6. Total circulating lymphocytes\> 1000 / mm3, 7. Availability of DNA and RNA from the tumor, 8. Information to the patient and signature of informed consent or his legal representative, 9. Affiliated with a social security scheme or such a scheme. Exclusion Criteria: 1. Inability to undergo study follow-up for geographical, social or psychological reasons, 2. Infection with HIV or hepatitis B or C viruses, 3. Patients on high dose corticosteroid treatment (\> 1 mg / kg continuously), 4. Any concomitant serious illness that may interfere with participation in the study or significantly affect the results of the study (pulmonary, heart or liver disease), 5. Contraindication to performing lymphapheresis (coagulation disorder, cardiovascular problems, venous access, hypocalcemia, psychological inability to undergo extracorporeal circulation, cachexia, etc.), 6. Pregnant patient or of childbearing age without effective contraception, 7. Persons deprived of their liberty, under guardianship or legal protection.
