About this study

It is also important to study other inflammatory and tumor biomarkers which would have a prognostic or even therapeutic value:

serum dosage of LDH (lactate dehydrogenase)
IL-6 (interleukin 6)
CRP (C-reactive protein)
absolute count of lymphocytes (CLA) and eosinophils
quantification of circulating tumor DNA before treatment and under treatment. The primary objective id to identify the epidemiological profile of the biological signature (PD-L1 / TMB / MSI/HRD/ TILs) of patients with locally advanced or metastatic breast carcinoma before and during the systemic treatment.

Questions about this trial

What is this clinical trial studying?

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 8 inclusion and 6 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: opening soon, as of the sponsor's last update on 23 May 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

Contact Monia Malek, MD (00216 28 101 505, monia.malek@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

number of eligible patients for immunotherapy (time frame: 2023 to 2027). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05871788.

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 23 May 2023; AzTrials last refreshed its copy on 8 Nov 2026.
