A Phase III Trial of Niraparib Versus Physician's Choice in HER2 Negative, Germline BRCA Mutation-positive Breast Cancer Patients

Brief Summary

The purpose of this study is to compare progression-free survival (PFS) in patients with advanced/metastatic breast cancer who have a BRCA mutation when treated with niraparib as compared to those treated with physician's choice

Beschreibung

This is a phase III, randomized, open label, multicenter, controlled trial of niraparib versus physician's choice in previously-treated, HER2 negative, germline BRCA mutation-positive breast cancer patients. Niraparib is an orally active PARP inhibitor. Niraparib (in a 2:1 ratio) will be administered once daily continuously during a 21-day cycle. Physician's choice will be administered on a 21-day cycle. Health-related quality of life will be measured. The safety and tolerability will be assessed by clinical review of adverse events (AEs), physical examinations, electrocardiograms (ECGs), and safety laboratory values.

• prior therapy should have included a taxane and/or anthracycline (unless contraindication to those) in the neoadjuvant, adjuvant, or advanced/metastatic setting.

• a. hormone receptor positive patients must also have hormone resistant disease; either relapsed while on adjuvant endocrine treatment, or within one year of completing adjuvant endocrine treatment, or progression on at least one line of endocrine treatment for advanced cancer.

• ecog performance status 0-2

• adequate bone marrow, kidney and liver function

Ausschlusskriterien

• patients with platinum resistant cancer

• symptomatic uncontrolled brain metastases

• prior diagnosis of stage iv ovarian cancer; stage iii ovarian cancer must have a 5-year disease-free interval; stage ii ovarian cancer must have a 2-year disease-free interval

• known hypersensitivity to the components of niraparib

• invasive cancer other than breast cancer within 2 years (except basal or squamous cell carcinoma of the skin that has been definitely treated)

• pregnant or breast feeding patients

• immunocompromised patients

• known active hepatitis b or c

• prior treatment with a parp inhibitor

• known history of myelodysplastic syndrome (mds).
