PALB2-PARPi-01: PARP-inhibitor on Advanced Metastatic Breast Cancer in Germline PALB2 Mutations Carriers
Study Details
Study Description
Brief Summary
The study aims at exploring the potential benefit of a PARP-inhibitor, Niraparib, in metastatic breast cancer developing in germline-PALB2 mutations carriers. This study is designed as a multicentre one-arm two-stage phase 2 clinical trial

Outcome Measures
Primary Outcome Measures
- 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
- Progression-free survival [12 months]
Time from inclusion to progression or death (all-cause) or last follow-up whichever occurs first
- Overall survival [12 months]
Time from inclusion to death (all-cause) or last follow-up whichever occurs first
- 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
- 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
- Adverse event rate [72 months]
Adverse events (clinical and biological) between inclusion and 72 months
- 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
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.

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.
