Circulating Tumor DNA and Follow-up of BRCA1 Mutation Carriers (CirCa 01)

January 29, 2024 updated by: Institut Curie
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).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

30 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Patient with no evidence of any invasive tumor mass at inclusion (clinical and, if any, radiological exams)
  2. Carriers of known germline BRCA1 deleterious mutation (a personal history of cancer is NOT mandatory).
  3. Age ≥ 30 years for patient with personal previous history of cancer
  4. Age ≥ 40 years for patient without personal previous history of cancer
  5. Patient who a follow-up visit is scheduled in the including center at least once a year
  6. Patient having health care insurance
  7. Signed informed consent by patient

Exclusion Criteria:

  1. Patient presenting with invasive tumor masses (e.g. stage IV cancer or localized cancer not yet surgically removed)
  2. Carriers of germline BRCA1 variant of unknown significance
  3. Carriers of germline BRCA2 deleterious mutation or variant
  4. Individuals with a low risk of BRCA1-related tumor growth, i.e. women who underwent prophylactic bilateral mastectomy AND adnexectomy.
  5. Any medical or other condition that in the Investigator's opinion rendered the patient unsuitable for this study
  6. Patient deprived from ability to decide on her own.
  7. Patient unable to have a regular follow up for geographical, social or psychological reasons.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: Blood sampling
Procedure: Blood sampling

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 the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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
Sensitivity = % of patients with detectable levels of mutated TP53 ctDNA among those who experience a new tumor growth (relapse and/or new tumor).
Up to 42 months
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
Time Frame: Up to 42 months
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).
Up to 42 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time Frame
Positive predictive value for mutated TP53 ctDNA
