Genetic roadmap for metastatic breast cancer: CATCH trial aims to match patients to targeted therapies
NCT ID NCT05652569
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
