Detailed Description

OBJECTIVES:

Primary

• Assessment of Anti tumour activity to PARP-1 inhibitor rucaparib in patients with locally advanced or metastatic breast or advanced ovarian cancer shown to express the BRCA 1 or 2 mutations.
• To evaluate the toxicity of treatment with Rucaparib in these population's.

Secondary

• To evaluate the time to progression and overall survival in patients treated with this drug.
• To study pharmacokinetics of this drug in these patient populations.
• To evaluate the Poly(ADP-ribose) polymerase (PARP) activity in peripheral blood lymphocytes from BRCA 1 and 2 heterozygotic patients.
• To determine a tolerable and effective dosing regimen of the Rucaparib oral formulation.

OUTLINE: This is a dose-escalation study followed by an open label multicenter study. The study was originally set up with an IV formulation. An oral formulation of the PARP-1 inhibitor rucaparib will be used from now on. Patients are stratified according to tumor type (breast vs ovarian) and mutation status ( BRCA 1 vs BRCA 2). In addition, patient with high-grade serous ovarian cancer can be enrolled into Stage 1 of the study. All patients enrolled will receive PARP-1 inhibitor rucaparib oral formulation once daily for either 7, 14, or 21 days of each cycle, (two possible dosages for 21 days treatment). Treatment repeats every 21 days for 12 courses in the absence of disease progression or unacceptable toxicity. Patients who achieve stable or responding disease may receive additional courses of treatment at the discretion of the chief investigator or Drug Development Office (DDO).

Patients undergo blood sample collection periodically for pharmacokinetic and pharmacodynamic studies. Samples are analyzed for tumor marker (CA 125 and/or CA 15.3) measurements, rucaparib plasma levels via liquid chromatography/mass spectrometry/mass spectrometry, PARP activity, and PARP protein expression via western blotting immunoassays. Paraffin embedded sections from original diagnostic biopsy are also collected and analyzed for PARP protein expression via immunohistochemical technique. Pleural and ascitic fluid may be collected and analyzed for DNA DS break repair proficiency via immunohistochemical technique. Some patients also undergo biopsy of tumors and samples are analyzed for BRCA 2 mutation as well as PARP activity via validated PARP immunoblotting assay.

After completion of study treatment, patients are followed for 28 days.

Description

INCLUSION CRITERIA

1. All stages of the study (IV and oral):

   Patients must be proven known carriers of a mutation of BRCA1 or BRCA2 or considered to be highly likely to be carriers of a BRCA1 or 2 mutation* (score of ≥ 20 as per Manchester criteria) and have histologically documented locally advanced or metastatic breast cancer or advanced ovarian cancer.

   *Patients considered highly likely to be carriers will be tested after consenting and a BRCA1 or 2 mutation must be confirmed for the patient to be eligible to receive treatment.

   Oral stage 1 only:

   In addition to the above, patients with high grade serous ovarian cancer with unknown BRCA status may be entered into oral stage 1.

2. Patients with ovarian cancer (including epithelial, fallopian tube cancer and primary peritoneal cancer) who have had no more than 5 prior chemotherapy regimens in the last 5 years. For the BRCA carriers > 2 months must have elapsed since their last treatment with a carboplatin- or cisplatin-containing regimen or for high grade serous ovarian cancer patients ≥ 6 months.
3. Patients with breast cancer who have had no more than 5 prior chemotherapy regimens in the last 5 years.
4. Measurable disease as measured by X-ray, computerised tomography (CT), or MRI scan as defined by RECIST criteria. These measurements must be done within 4 weeks of the patient going on study. Clinical measurements must be done within one week of the patient going on study. Patients with bone disease must have other measurable disease for evaluation. Previously irradiated lesions cannot be used for measurable disease.
5. Life expectancy of at least 12 weeks
6. World Health Organisation (WHO) performance status of 0 or 1 (Appendix 1)

7. Haematological and biochemical indices within the ranges shown below. These measurements must be performed within one week before the patient goes on study.

   Lab Test Value Required Haemoglobin (Hb) ≥9.0 g/dl Neutrophils ≥1.5 x 10^9/L Platelets (Plts) ≥100 x 10^9/L Serum bilirubin ≤1.5 x upper normal limit Alanine amino-transferase (ALT) and/or ≤ 2.5 x upper limit of normal (ULN) aspartate amino-transferase (AST) unless due to tumour in which case up to 5 x ULN is permissible Glomerular Filtration Rate (GFR) calculated either by the Wright formula ≥50 ml/min or Cockcroft-Gault formula or by isotope clearance measurement

8. 18 years or over
9. Written (signed and dated) informed consent and be capable of co-operating with treatment and follow-up

EXCLUSION CRITERIA

1. Radiotherapy (except for palliative reasons), endocrine therapy, immunotherapy, chemotherapy, biological agents or investigational agents during the previous 4 weeks (6 weeks for nitrosoureas and Mitomycin-C) before treatment.
2. Ongoing toxic manifestations of previous treatments. Exceptions to this are alopecia or certain Grade 1 toxicities, which in the opinion of the Investigator and the Drug Development Office (DDO) should not exclude the patient.
3. Known brain metastases.
4. Female patients able to become pregnant (or already pregnant or lactating). However, those female patients who have a negative serum or urine pregnancy test before enrolment and agree to use two highly effective forms of contraception (oral, injected or implanted hormonal contraception and condom, have an intrauterine device and condom, diaphragm with spermicidal gel and condom, or are surgically sterilised) 4 weeks before entering the trial, during the trial and for 6 months afterwards are considered eligible.
5. Male patients with partners of child-bearing potential (unless they agree to use one form of highly effective contraception such as a barrier method of condom plus spermicide during the trial and for 6 months afterwards).
6. Major thoracic and/or abdominal surgery in the preceding 4 weeks from which the patient has not recovered.
7. At high medical risk because of non-malignant systemic disease including active uncontrolled infection.
8. Concurrent malignancies at other sites, with the exception of adequately treated cone-biopsied in situ carcinoma of the cervix uteri and basal or squamous cell carcinoma of the skin and concurrent breast and ovarian carcinoma. Cancer survivors, who have undergone potentially curative therapy for a prior malignancy, are eligible for the study.
9. Patients with active or unstable cardiac disease or history of myocardial infarction within 6 months. Patients with cardiovascular signs or symptoms should have a MUGA scan or echocardiogram, and those patients with left ventricular ejection fraction (LVEF) below the institutional limit of normal should be excluded.
10. Any other condition which in the Investigator's opinion would not make the patient a good candidate for the clinical trial.
11. Patients who have already received a PARP inhibitor.
