About this study

Official title: Molecular Profiling Using FoundationOne CDx in Young (<50 Years of Age) Patients With Metastatic Breast Cancer (ML41263)

Breast cancer is the most common cancer in women worldwide, especially in developed countries. In developing countries, including South Korea, the incidence and mortality rate of breast cancer is rapidly increasing. One of the most important characteristics of breast cancer in South Korea, as well as in other Asian countries, is the younger onset of disease compared to Western.

Medical treatment of breast cancer is evolving rapidly, incorporating immune checkpoint blockades and molecularly targeted agents. However, data and knowledge are still limited in terms of molecular characteristics of Asian breast cancer, compared to that of Western countries, and this remains a major hurdle for drug development in Asian breast cancer patients.

The primary objective of this study is to elucidate the genetic characteristic of young (<50 years of age) Korean patients with metastatic breast cancer using FoundationOne CDx.

Read the detailed description

Secondary Objective(s):

  1. To evaluate the prognostic and predictive role of tumor mutation burden.
  2. To reveal the correlation between genetic characteristics and immunohistochemical expression of selected proteins (including DNA damage repair (DDR) molecules and various immune modulating molecules including PD-L1, PD-1, IDO, and OX40).
  3. Compare molecular characteristics of breast cancer according to age groups (<35 years vs. 35-50 years).
  4. To offer genomic profiling guided therapy to patients as early as possible (preferably, 1st- or 2nd-line of treatment). In addition, to explore how genomic profiling guided therapy could improve patient outcome as an ad-hoc if sufficient number of patients can be followed up (compared to historic data).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Genetic characteristic of young (<50 years of age) Korean patients with metastatic breast cancer.

    Genetic characteristics will be evaluated using FoundationOne CDx.

    Measured: After the end of patient enrollment

Secondary outcomes (4)
  1. Evaluate the prognostic and predictive role of tumor mutation burden

    Tumor mutation burden will be analysed using FoundationOne CDx.

    Measured: After the end of patient enrollment

  2. Reveal the correlation between genetic characteristics and immunohistochemical expression of selected proteins.

    FoundationOne CDx results and immunohistochemical expression will be analysed.

    Measured: After the end of patient enrollment

  3. Compare molecular characteristics of breast cancer according to age groups.

    Genetic characteristics will be analysed according to age groups.

    Measured: After the end of patient enrollment

  4. To offer genomic profiling guided therapy to patients To explore how genomic profiling guided therapy could improve patient outcome as an ad-hoc if sufficient number of patients can be followed up (compared to historic data).

    The result of FoundationOne CDx will be used in patient treatment

    Measured: After the end of patient enrollment

Questions about this trial

What is this clinical trial studying?

A study testing FoundationOne CDx in people with Breast Cancer, run by Seoul National University Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 17 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Genetic characteristic of young (<50 years of age) Korean patients with metastatic breast cancer. (time frame: After the end of patient enrollment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Apr 2025.
