These patients will be followed up during 30 months (2,5 years) with mutated TP53 mutation detection or during 42 months (3,5 years) with mutated TP53 mutation detection and circulating tumor cells detection… Read more about this study

  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patient with no evidence of any invasive tumor mass at inclusion (clinical and, if any, radiological exams)

About this study

BRCA1 carriers who are at high risk of developing either a relapse and/or a new cancer growth will be included. These patients will be followed up during 30 months (2,5 years) with mutated TP53 mutation detection or during 42 months (3,5 years) with mutated TP53 mutation detection and circulating tumor cells detection (CTC) performed at each hospital visit (for technical reason only patients included at Institut Curie will be proposed to participate to the CTC substudy).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Blood samplingProcedure or surgery

    Patients will have a blood draw at each visit to the hospital,

    • with a maximum of 1 blood draw every 3 months, in absence of any abnormal clinical/radiological exam
    • with a maximum of 1 blood draw every week, in case of abnormal clinical/radiological exam that requires further investigation

What is being measured

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

  1. Sensitivity of plasma TP53 mutation detection as a test to detect any tumor growth (relapse and/or new tumor) during the follow-up of women known to carry BRCA1 germline mutation

    Sensitivity = % of patients with detectable levels of mutated TP53 ctDNA among those who experience a new tumor growth (relapse and/or new tumor).

    Measured: Up to 42 months

  2. Specificity of plasma TP53 mutation detection as a test to detect any tumor growth (relapse and/or new tumor) during the follow-up of women known to carry BRCA1 germline mutation

    Specificity = % of patients with undetectable levels of mutated TP53 ctDNA among those who don't experience a new tumor growth (diagnosed within 6 months after the blood draw).

    Measured: Up to 42 months

Secondary outcomes (6)
  1. Positive predictive value for mutated TP53 ctDNA

    Positive predictive value = Probability of having a tumor growth (relapse and/or new tumor) when mutated TP53 ctDNA is detectable.

    Measured: Up to 42 months

  2. Negative predictive value for mutated TP53 ctDNA

    Negative predictive value = Probability of being without tumor growth when mutated TP53 ctDNA is not detectable.

    Measured: Up to 42 months

  3. Sensitivity of circulating tumor cells detection as a test to detect any tumor growth (relapse and/or new tumor) during the follow-up of women known to carry BRCA1 germline mutation

    Sensitivity = % of patients with detectable levels of circulating tumor cells among those who experience a new tumor growth (relapse and/or new tumor).

    Measured: Up to 42 months

  4. Specificity of circulating tumor cells detection as a test to detect any tumor growth (relapse and/or new tumor) during the follow-up of women known to carry BRCA1 germline mutation

    Specificity = % of patients with undetectable levels of circulating tumor cells among those who don't experience a new tumor growth (diagnosed within 6 months after the blood draw).

    Measured: Up to 42 months

  5. Positive predictive value for circulating tumor cells

    Positive predictive value = Probability of having a tumor growth (relapse and/or new tumor) when circulating tumor cells is detectable.

    Measured: Up to 42 months

  6. Negative predictive value for circulating tumor cells

    Negative predictive value = Probability of being without tumor growth when circulating tumor cells is not detectable.

    Measured: Up to 42 months

Questions about this trial

What is this clinical trial studying?

A study testing Blood sampling in people with Women With BRCA1 Germline Deleterious Mutation, run by Institut Curie at 4 sites in France.

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 7 inclusion and 7 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 31 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in France. 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?

Sensitivity of plasma TP53 mutation detection as a test to detect any tumor growth (relapse and/or new tumor) during the follow-up of women known to carry BRCA1 germline mutation (time frame: Up to 42 months). The study lists 2 primary outcomes in all. 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 31 Jan 2024.
