| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
The objective of this phase-III trial is to compare the efficacy and safety of sorafenib in combination with capecitabine versus capecitabine in combination with placebo in the treatment of subjects with locally advanced or metastatic HER2-negative breast cancer who are resistant to or have failed prior taxane and an anthracycline or for whom further anthracycline therapy is not indicated.
The primary efficacy endpoint is progression-free survival (PFS). |
|
| E.2.2 | Secondary objectives of the trial |
Secondary efficacy endpoints are overall survival (OS), time to progression (TTP), overall response rate (ORR), disease control rate (DCR) and duration of response (DoR). Patient reported outcomes (PROs) include an evaluation of breast cancer symptoms using the Functional Assessment of Cancer Therapy-Breast Symptom Index (8 item) (FBSI-8) questionnaire and health-related quality of life (HRQoL) using the EuroQoL 5 Dimension Questionnaire.
Safety evaluations comprise adverse event reporting and assessment of laboratory abnormalities.
In addition, this trial includes an exploratory analysis of biomarkers and estimation of capecitabine, 5-FU, and sorafenib exposures.

|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
•Age is ≥18 years.
•Life expectancy is at least 12 weeks (3 months).
•Subject has histologically or cytologically confirmed HER2-negative adenocarcinoma of the breast. HER2 status should be determined by an accredited laboratory by immunohistochemistry (IHC), fluorescence in situ hybridization (FISH), or chromogenic in situ hybridization (CISH). Note: local accreditation is acceptable.
•Subject has locally advanced or metastatic disease; locally advanced disease must not be amenable to resection with curative intent (Stage IIIb or IIIc; American Joint Committee on Cancer [AJCC] Staging System, Sixth Edition).
•Subject has measurable or non-measurable (but radiologically evaluable) disease (according to RECIST 1.1).
•All computer tomography [CT] [with contrast] and magnetic resonance imaging [MRI]) used to document disease must have been done ≤ 4 weeks before randomization. Bone scans (if clinically indicated) must be done ≤ 12 weeks prior to randomization.
•Subject must have received up to two prior chemotherapy regimens (adjuvant/neo adjuvant treatments are considered one regimen), and no more than one prior regimen for advanced and/or metastatic disease. Chemotherapy regimens include both targeted and biologic therapy.
•Prior regimens must have included an anthracycline (eg, doxorubicin, epirubicin) and a taxane (eg, paclitaxel, docetaxel), either in combination or in separate regimens, in either the neo-adjuvant/adjuvant or the metastatic setting or both, as either monotherapy or as part of a combination with another agent. Sequential regimens will count as a single regimen; multiple neo-adjuvant / adjuvant regimens will count as a single regimen.
•Subject must meet at least one of the following scenarios to be eligible for the study (see Appendix 14.19 in the protocol for definitions of treatment resistance and failure):
-Resistant to or have failed prior taxane and anthracycline
OR
-Resistant to or have failed prior taxane AND for whom further anthracycline therapy is not indicated (eg, intolerance or cumulative doses of doxorubicin or doxorubicin equivalents [eg, epirubicin]).
NOTE: No minimum dose of prior anthracycline or anthracycline equivalents is required.
•Subjects who relapse beyond 12 months after the last taxane or anthracycline dose given in the adjuvant, neo-adjuvant, or metastatic setting are eligible. Further therapy with the agent(s) for a subsequent regimen must have been considered and ruled out for example due to: prior toxicity, intolerance, or local standard of practice (see Appendix 14.19 in the protocol for definitions of treatment intolerance).
•Single agent experimental (not approved) chemotherapy is not allowed. Prior experimental chemotherapy treatment is allowed, provided it is given in combination with at least one drug approved for the treatment of breast cancer (excluding drugs that target VEGF or VEGFR, eg, bevacizumab, brivanib, sunitinib, vatalinib).
•Subject must have discontinued prior chemotherapy, including both targeted and biologic therapies, prior therapeutic radiation therapy, or prior hormonal therapy for locally advanced or metastatic disease ≥ 4 weeks (28 days) before randomization. Start of study treatment is allowed within less than 28 days of the prior therapy provided that 5 half-lives of the prior treatment drug(s) have elapsed before randomization. Previously radiated areas must not be the only site of disease, unless the site had subsequent evidence of progression. Palliative radiation to bone metastasis for pain control is permitted with provisions (see Section 6.9).
•ECOG performance status 0 or 1 (see Appendix 14.1 in the protocol).
•Adequate bone marrow, liver, and renal function within 7 days prior to randomization as assessed by:
-Hemoglobin (Hgb) ≥ 9 g/dL (transfusion and growth factor independent).
-Prothrombin time (PT), prothrombin time-international normalized ratio (PT-INR) ≤ 1.5 X ULN and partial thromboplastin time (PTT) or activated partial thromboplastin time (aPTT) ≤ 1.5 X ULN.
-Prophylactic anticoagulation as described below is permitted:
- Low dose warfarin (1 mg orally [PO], once daily [QD]) with PT-INR ≤ 1.5 x ULN. For subjects receiving prophylactic doses of warfarin, the PT-INR should be measured prior to initiation of trial drugs (sorafenib/placebo and capecitabine) and should be monitored at least weekly, or as defined by the local standard of care, until it is stable.
- Low-dose aspirin (≤ 100 mg daily).
- Prophylactic doses of heparin/heparinoids. |
|
| E.4 | Principal exclusion criteria |
•HER2-positive breast cancer (IHC ≥ 3+, positive FISH, or positive CISH); equivocal or unknown HER2 status. Subjects with equivocal HER2 status may consent to having their HER2 status retested prior to enrollment by an accredited laboratory.
•Unknown hormone receptor status (estrogen and progesterone receptor).
•No prior taxane and anthracycline for the treatment of breast cancer (either in adjuvant, neo-adjuvant or metastatic setting).
•Bilateral breast cancer or a history of two distinct breast cancers are excluded.
•Inflammatory breast carcinoma are excluded.
•Subject must NOT have
oactive or clinically significant cardiac disease.
othrombotic, embolic, venous, or arterial events within 6 months before randomization.
oany hemorrhage/bleeding event of NCI-CTCAE v4.0 Grade 3 or above within 4 weeks before randomization.
•Radiation to any lesions < 4 weeks prior to randomization. Palliative radiation to bone metastasis for pain control is permitted with provisions. |

| E.5 End points |
| E.5.1 | Primary end point(s) |
| The primary efficacy variable will be progression free survival, measured from the date of randomization to the date of first observed disease progression (radiological assessment according to RECIST 1.1 criteria for progression of non-measurable and measurable disease) or the date of death due to any cause (if death occurs before disease progression). |
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
| The main analysis of the study will be performed when approximately 250 PFS events (including progression being based on the assessments of the blinded independent central review panel and death if death occurs before progression) are observed. At the time approximately 250 PFS events are reached, if the observed number of deaths is less than approximately 270, the trial will continue and remain blinded until approximately 270 deaths are observed. In such a case, the analysis of PFS will include all PFS data up to the later data cutoff date for approximately 270 deaths. A second analysis will be done when approximately 405 deaths are observed. |

| E.5.2 | Secondary end point(s) |
Secondary efficacy endpoints are OS, TTP, ORR, DCR and duration of response (DoR).
