Trial summary

This project aims to investigate the role of MMA in breast cancer. To this end, we will measure MMA on serum samples collected at the time of breast cancer diagnosis, to investigate the role of MMA in predicting long-term recurrence risk, response to neoadjuvant chemotherapy, and its association with age and clinical… Read more about this study

About this study

Official title: A Retrospective Study Exploring the Role of Serum Methylmalonic Acid (MMA) in Breast Cancer---focusing on Metastasis, Chemotherapy Resistance, and Ageing Effects

This project aims to investigate the role of MMA in breast cancer. To this end, we will measure MMA on serum samples collected at the time of breast cancer diagnosis, to investigate the role of MMA in predicting long-term recurrence risk, response to neoadjuvant chemotherapy, and its association with age and clinical frailty.

This project aims to investigate the role of MMA in breast cancer. To this end, we will measure MMA on serum samples collected at the time of breast cancer diagnosis, to investigate the role of MMA in predicting long-term recurrence risk, response to neoadjuvant chemotherapy, and its association with age and clinical frailty. If the role of baseline serum MMA in therapy resistance and/or metastasis is confirmed, our study could be further extended by evaluating SOX4 expression in the tumor tissues (SOX4 is activated by MMA, and SOX4 induces EMT (epithelial to mesenchymal transition) and the metastasis process.

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by KU Leuven at 1 site in Belgium.

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 5 inclusion and 5 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: finished, as of the sponsor's last update on 22 Jul 2022. 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 Belgium. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

MMA levels (time frame: baseline). 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 22 Jul 2022.
