NCT ID NCT05652569

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

The CATCH trial is a large observational study for people with metastatic breast cancer. It uses advanced genetic testing on tumor biopsies to find unique biomarkers and drug targets. The goal is to create a precision medicine platform that helps guide patients toward the most promising clinical trials and targeted treatments. This study does not test a new drug itself but aims to improve how treatments are chosen.

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 platform could help match more metastatic breast cancer patients with targeted therapies and clinical trials tailored to their tumor's genetic profile.
What could go wrong
This is an observational diagnostic study, not a treatment trial. It may not directly improve outcomes, and genomic profiling may not always find actionable targets.

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

Inclusion Criteria: * Female and male breast cancer patients ≥ 18 or if the legal guardian has agreed to the respective informed consent form (ICF) * Patients with advanced or metastatic breast cancer (irrespective of clinical parameters such as TNM, subgroups, therapy lines) * Patients, who agreed to and were able to sign the informed consent form. Exclusion Criteria: * Early breast cancer * Inability to take a tissue bioptic sample due to reasons such as physical location of the lesion or health of the patient * Any physical or mental handicap or severe comorbidities that would hamper the adequate cooperation with the patient.
