Outcome Measures

Primary Outcome Measures

  1. Objective response rate [4 months]

    Complete or partial tumour response according to RECIST 1.1 criteria accounting for objective response rate in solid tumours at 4 cycles., based on the CT-Scan

Secondary Outcome Measures

  1. Progression-free survival [12 months]

    Time from inclusion to progression or death (all-cause) or last follow-up whichever occurs first

  2. Overall survival [12 months]

    Time from inclusion to death (all-cause) or last follow-up whichever occurs first

  3. Tumoral response [12 months]

    Partial Response or Complete Response or Stable Disease, as per to RECIST 1.1 criteria for tumoral response, based on CT-Scan

  4. Duration of response [12 months]

    Time to treatment failure, defined as time between inclusion and treatment discontinuation (any reason: death, disease progression, toxicity) or last follow-up

  5. Adverse event rate [72 months]

    Adverse events (clinical and biological) between inclusion and 72 months

  6. Quality of Life variation [12 months]

    European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life C30 Questionnaire, evaluated every 3 months, from inclusion to 12 month

Eligibility Criteria

Criteria

Ages Eligible for Study:
18 Years and Older
Sexes Eligible for Study:
All
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  • Adult patients over 18 years

  • PALB2 germline heterozygous mutation carrier, wild type BRCA1&2 (breast cancer 1&2) affected with metastatic breast cancer in first metastatic treatment line or beyond

  • Histologically or cytologically confirmed breast cancer with evidence of metastatic disease.

  • Triple Negative breast cancer; Patients affected with triple negative cancers should have received anthracyclines and taxanes in neo/adjuvant therapy.

  • Or patients with Hormonal receptor positive (HR+)/ Human epidermal growth factor receptor 2 negative (HER2-) breast cancer, with treatment failure after a second line of therapy; Estrogen Receptor/ProgesteroneReceptor breast cancer positive patients must have received and progressed on currently recommended therapies in this indication (endocrine therapy, CDK4/6 inhibitors (adjuvant or metastatic)), or have a disease form that the treating physician believes to be inappropriate for recommended therapies in this indication.

  • Prior therapy with an anthracycline and a taxane in an adjuvant setting.

  • Prior platinum allowed as long as no breast cancer progression occurred on treatment or if given in adjuvant/neoadjuvant setting, at least 12 months elapsed from last dose to study entry.

  • Eastern Cooperative Oncology Group (ECOG) performance status 0-2.

  • Adequate bone marrow, kidney and liver function.

  • Patients without visceral crisis

Exclusion Criteria:
  • Patients with HER2 positive disease.

  • Untreated and/or uncontrolled brain metastases.

  • Patients in visceral crisis requiring chemotherapy

  • Cytopenia, defined with the following thresholds: (i) Neutrophil count < 1500/mm3; Platelet count< 100 000/mm3; Hemoglobin <9g/dL

  • Prior malignancy unless curatively treated and disease-free for > 5 years prior to study entry. Prior adequately treated non-melanoma skin cancer, in situ cancer of the cervix, ductal carcinoma in situ (DCIS) or stage I grade 1 endometrial cancer allowed.

  • Known HIV (Human Immunodeficiency Virus) infection.

  • Pregnant or breast-feeding women.

  • Lack of affiliation to a social security benefit plan (as a beneficiary or assignee)
