E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to compare progression-free survival (PFS), as assessed by blinded central review, of patients with advanced/metastatic HER2-negative gBRCAmut breast cancer when treated with niraparib as compared to those treated with physician’s choice single agent chemotherapy standards (eribulin, vinorelbine, gemcitabine or capecitabine). |
|
E.2.2 | Secondary objectives of the trial |
(1) Key Secondary Objective: To compare overall survival of patients with advanced/metastatic HER2-negative gBRCAmut breast cancer when treated with niraparib as compared to those treated with physician’s choice single agent chemotherapy standards.
(2) Other Secondary Objectives:
- To evaluate safety and tolerability as measured by all AEs
- To compare PFS using investigator assessment of progression
- To evaluate time to treatment failure
- To compare response rate and duration of response
- To compare time to deterioration of health-related quality of life (HRQoL
- To describe subsequent therapies and potential relationships with outcomes
- To assess genetic and non-genetic biomarkers relating to treatment efficacy.
- To assess outcomes by germline mutation BRCA1 vs BRCA2 |

9. No prior treatment with a known or putative PARP inhibitor (except iniparib). No other anticancer agent (chemotherapy, hormonal therapy, or other agent) is to be permitted during the course of the study for any patient.

c. Hemoglobin ≥ 9 g/dL
d. Serum creatinine ≤ 1.5 × upper limit of normal (ULN) or ≥ 60 mL/min using Cockcroft-Gault equation
e. Total bilirubin ≤ 1.5 × ULN OR direct bilirubin ≤ ULN
f. Aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 2.5 × ULN or < 5 × ULN with liver metastases
13. Patients able to swallow and retain oral tablets
14. Female patients must not be pregnant or breast feeding
a. Female patient of childbearing potential must have a negative serum pregnancy test.
15. Patients of child bearing potential and their partners with whom they are sexually active must agree to the use of 2 highly effective forms of contraception from randomization, throughout the study and until 3 months after the last dose of study drug.
16. No known hypersensitivity to the components of niraparib or any of its analogs.
17. No major surgery within 2 weeks prior to registration. Patients must have recovered from earlier major surgery before registration.
18. No prior diagnosis of Stage IV ovarian cancer
-Patients with history of Stage III ovarian cancer must have a 5-year disease-free interval and a normal serum carcinoma antigen 125 (CA125)
-Patients with Stage I or II ovarian cancer must have a disease-free interval of 2 years and a normal serum carcinoma antigen 125 (CA 125)
19. No prior diagnosis, detection, or treatment of invasive cancer other than breast cancer within 2 years (except basal or squamous cell carcinoma of the skin that has been definitively treated)
20. Patients must not be considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease, or active, uncontrolled infection. |
