Treatment regimen utilizing neratinib for breast cancer
View Patent ↗An extended regimen for treatment of HER-2/neu overexpressed/amplified cancer is described, with involves delivering a course of neratinib therapy to HER-2/neu overexpressed/amplified cancer patients following the completion of surgical and adjuvant therapy. The neratinib regimen may be continued for upwards of twelve months to five years. Also provided are pharmaceutical kits designed to facilitate compliance with the regimen.
1. A regimen for treatment of early stage HER-2 positive breast cancer comprising delivering neratinib therapy to early stage HER-2 positive breast cancer patients at the completion of at least twelve cycles of trastuzumab adjuvant therapy; wherein the neratinib therapy is started about 2 weeks to about one year from the completion of surgical and standard adjuvant therapy.
2. The regimen according to claim 1 , wherein the course of neratinib therapy is in the range of 8 months to 5 years.
3. The regimen according to claim 1 , wherein the cancer patients are treated with neratinib for at least about 12 months.
4. The regimen according to claim 1 , wherein neratinib is delivered orally.
5. The regimen according to claim 4 , wherein neratinib is delivered in tablet form.
6. The regimen according to claim 1 , wherein neratinib is administered daily.
7. The regimen according to claim 1 , wherein neratinib is delivered at a dose of 120 mg to 300 mg daily.
8. The regimen according to claim 7 , wherein neratinib is delivered at a dose of 240 mg.
9. A method for improving invasive disease-free survival (IDFS) or disease-free survival (DFS)-HER 2 positive ductal carcinoma in situ (DCIS) and/or improvements in overall survival, time to distant recurrence, and/distant disease-free survival in an early stage HER-2 positive breast cancer patient, said method comprising delivering neratinib to said patient following the completion of at least twelve cycles of trastuzumab adjuvant therapy; wherein the neratinib therapy is started about 2 weeks to about one year from the completion of surgical and standard adjuvant therapy.
10. The method according to claim 9 , wherein the patient received standard adjuvant therapy consisting of trastuzumab and one or more chemotherapy.
11. The method according to claim 10 , wherein the chemotherapy involved one or more of doxorubicin, cyclophosphamide, paclitaxel, docetaxel, carboplatin, lapatinib, pertuzumab, bevacizumab, trastuzumab-DM-1, and anthracycline based therapy.
12. A regimen for improving invasive disease free survival, disease-free survival-HER 2 positive ductal carcinoma in situ, overall survival, time to distant recurrence, and/or distant disease-free survival comprising treating early stage HER-2 positive breast cancer patients with neratinib for at least twelve months, wherein said treatment with neratinib following the completion of at least at least twelve cycles of adjuvant therapy with trastuzumab; and wherein the neratinib therapy is started about 2 weeks to about one year from the completion of surgical and standard adjuvant therapy.
13. The regimen according to claim 12 , wherein the neratinib therapy commences about six months to about twelve months following the completion of trastuzumab therapy.
14. The regimen according to claim 12 , wherein the patients are further undergoing concomitant therapy selected from one or more of bisphosphonates for osteopenia or osteoporosis and endocrine therapy.
15. The regimen according to claim 1 , wherein the early stage HER-2 positive breast cancer patient is a hormone receptor positive patient.
16. The regimen according to claim 15 , wherein the hormone receptor positive patient is an estrogen receptor or progesterone receptor positive patient.
17. The regimen according to claim 9 , wherein the early stage HER-2 positive breast cancer patient is a hormone receptor positive patient.
18. The regimen according to claim 17 , wherein the early stage HER-2 positive breast cancer patient is an estrogen receptor or progesterone receptor positive patient.
