简要总结
This is a phase l/II study. The purpose of this study is to test the safety of the study drug neratinib in combination with a standard chemotherapy drug called capecitabine at different doses to find out what effects, if any, it has on people. Capecitabine (Xeloda®) is approved by the Food and Drug Administration (FDA) for advanced breast cancer treatment. Neratinib is an investigational drug, meaning the FDA has not approved the use of this drug for advanced breast cancer. The combination of capecitabine and neratinib has been studied before in another study where capecitabine was administered using the standard dosing schedule. In this study, the investigators want to find out if a different dosing schedule of capecitabine combined with neratinib is safer. This different dosing schedule is experimental, meaning the administration schedule of capecitabine and neratinib is not FDA approved for treatment for HER2 positive advanced breast cancer.

- •Negative β-human chorionic gonadotropin (hCG) pregnancy test for premenopausal women of reproductive capacity (those who are biologically capable of having children) and for women less than 12 months after menopause.
- •Women of childbearing potential must agree and commit to the use of a highly effective method of contraception as determined to be acceptable by the investigator, from the time of informed consent until 28 days after the last dose of the investigational product. Men must agree and commit to use a barrier method of contraception while on treatment and for 3 months after last dose of investigational products.
- •Provide written, informed consent to participate in the study and follow the study procedures
排除标准
- •Active uncontrolled cardiac disease, including cardiomyopathy, congestive heart failure (New York Heart Association functional classification of ≥2), unstable angina, myocardial infarction within 12 months of enrollment, or ventricular arrhythmia
- •Received prior therapy resulting in a cumulative epirubicin dose >900 mg/m2 or cumulative doxorubicin dose >450 mg/m
- •If another anthracycline or more than one anthracycline has been used, the cumulative dose must not exceed the equivalent of 450 mg/m^2 doxorubicin.
- •Any major surgery ≤28 days prior to the initiation of investigational products, or received anti-cancer therapy (including chemotherapy, biological therapy, hormonal therapy, investigational agents, or other anti-cancer therapy) administered ≤14 days prior to the initiation of investigational products.

研究组 & 干预措施
capecitabine 7/7 with neratinib
In the phase I portion of the study, a 3+3 design will be used. Once the MTD is reached, the phase II portion will enroll up to 24 patients. Capecitabine will be taken orally in AM and PM (at the assigned dose per cohort) 7 days on and 7 days off. Neratinib is given as 240 mg daily continuously without stopping. A cycle is 28 days. Patients will be seen on Day 1 of each cycle (+/- 3 days).
The MD has been determined as 240mg of neratinib and 1000mg BID of capecitabine.

结局指标
主要结局
Maximum Tolerated Dose (MTD)
时间窗: 1 year
If 0 of the 3 patients entered at a dose level experiences a DLT, another 3 patients will be treated at the next higher dose level. If 1 of 3 patients in a cohort experiences a DLT, then up to 3 additional patients will be treated at the same dose level. If none of these 3 additional patients experience a DLT, then the dose will be escalated to the next higher dose level. If \> 2 of the initial 3 or 6 patients at a dose level experience a DLT, then the MTD will have been exceeded, and de-escalation is warranted. De-escalation will continue if \> 2 of the initial 3 or 6 patients in a dose level cohort experience a DLT. There will be 2 dose de-escalation levels (dose levels -1 and -2) and one dose escalation (dose level +1) as shown in the table below. If \< 1 of 6 patients, at that dose level, experience a DLT, then that dose level will be confirmed as the MTD.
