Study information
Scientific title
Window study of the PARP inhibitor rucaparib in patients with primary triple negative or BRCA1/2 related breast cancer (RIO)
Acronym
RIO
Study hypothesis
The aim of the RIO trial is to determine the percentage of primary TNBCs or BRCA1/2 related breast cancers that display sensitivity to the PARP inhibitor rucaparib by measuring change in tumour cells multiplying after 12-14 days of rucaparib treatment. RIO will also aim to identify biomarkers that can identify patient groups sensitive to this medication to allow further analysis of rucaparib in these cancers.

Eligibility
Participant inclusion criteria
1. Male or female patients aged 16 years or older
2. Histologically proven carcinoma of the breast amenable to biopsy
3. Either breast tumour size 2cm or greater OR <2cm tumour with cytologically or histologically confirmed axillary lymph node metastases
4. WHO performance status 0, 1 or 2
5. Either:
5.1. Primary sporadic triple negative breast cancer defined as oestrogen receptor (ER) negative, progesterone receptor (PgR) negative (as defined by Allred score 0/8 or 2/8 or stain in <1% of cancer cells) and HER2 negative (immunohistochemistry 0/1+ or negative in situ hybridization) as determined by local laboratory. Patients should not be known to have a germline pathogenic BRCA1 or BRCA2 mutation at study entry.
OR
5.2. Primary BRCA1/2 related breast cancer as defined by a breast carcinoma of any phenotype (ER +ve or –ve, PgR +ve or –ve, HER2 +ve or –ve) occurring in a patient with a known germline pathogenic BRCA1 or BRCA2 mutation
6. Adequate organ function confirmed by the following laboratory values obtained within 14 days prior to the first dose of rucaparib:
6.1. Bone marrow function: ANC ≥ 1.5 x 109/L; Platelets >100×109/L; Hemoglobin ≥9 g/dL
6.2. Hepatic function: Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 x upper limit of normal (ULN); Bilirubin ≤1.5 x ULN
6.3. Renal function: serum creatinine ≤1.5 x ULN
7. Patients or patients with partners of childbearing potential must use adequate contraception during trial participation. A negative pregnancy test is required by female patients prior to the of therapy. Female patients will be deemed not of childbearing potential if they are postmenopausal (aged >50 and amenorrhoeic for at least 12 months) or have had irreversible surgical sterilization
8. ER negative patients may enter the trial whether or not they have taken hormone replacement therapy (HRT) or the oral contraceptive pill (OCP) within the last four weeks. ER positive patients on HRT or the OCP must either continue HRT/OCP for the duration of the study or must not have taken HRT/OCP within the last four weeks before trial entry. The possible benefits and risks of continuing HRT/OCP must be discussed with the patient
9. Patients with primary breast cancer and evidence of metastatic disease on first presentation are eligible providing they have not had prior treatment
10. Patients must be willing and able to provide informed consent and to comply with all study procedures (including providing additional tumour biopsies for research purposes) and visit schedules
