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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 investigating why some melanomas stop responding to immunotherapy. Researchers will take biopsies from 20 patients with advanced melanoma before and after treatment to see how tumor metabolism changes. The goal is to understand resistance mechanisms and find new ways to target cancer cells without harming immune cells.

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 research could point toward new ways to overcome immunotherapy resistance in melanoma, potentially leading to more effective treatments.
What could go wrong
This is a small, early-stage observational study with only 20 participants. It is not testing a treatment, so it may not directly lead 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 20 people

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

Started

May 2022

Expected to finish

Oct 2028

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: * Female or male, 18 years of age or older * Stage III unresectable or histologically confirmed stage IV cutaneous melanoma (melanoma of unknown origin is accepted), treatment naïve (metastatic stage) and for which immunotherapy will be started * Performance Status ≤1 * BRAF status available; BRAF status determination is required but patient will be eligible regardless of BRAF status * For women of childbearing potential, effective contraception must be initiated during the study. * Patient affiliated to social security plan * Patient having signed informed consent Exclusion Criteria: * Breastfeeding or pregnant patients: for women of childbearing age, a urine pregnancy test will be performed * Patients with ocular or mucosal melanoma of metastatic ocular melanoma * Patients with metastatic melanoma not treated with immunotherapy (i.e. treated with a combination of targeted therapies). * Contraindication to the initiation of immunotherapy: HIV and/or HCV and/or HBV positive, active autoimmune disease (chronic inflammatory bowel disease such as ulcerative colitis, Crohn's disease, vasculitis, etc.), patients with autoimmune motor neuropathy (such as Guillain Barré syndrome). * Vulnerable patients: minors, adults under guardianship or curatorship, deprived of liberty * Vulnerable persons (minors, patients under guardianship or curatorship, deprived of liberty, under court protection, etc.). * A psychiatric or addiction history that will compromise the patient's ability to consent and follow the proper protocol procedures * Any other clinical finding that, in the opinion of the principal investigator, could interfere with the results of the study or pose a risk to the patient during the study.
