Study Evaluating Neratinib Versus Lapatinib Plus Capecitabine For ErbB2 Positive Advanced Breast Cancer
This is a study of an experimental drug (neratinib) versus a combination of drugs (lapatinib and capecitabine) in women who have erbB-2 (HER-2) positive metastatic or locally advanced breast cancer. The goal of this study is to compare the two regimens in shrinking tumors and extending the lives of women with erbB2 (HER2) positive breast cancer. The study will also compare the safety of the two regimens and to compare quality of life of patients taking the two regimens.

A Study of Neratinib Plus Capecitabine Versus Lapatinib Plus Capecitabine in Patients With HER2+ Metastatic Breast Cancer Who Have Received Two or More Prior HER2 Directed Regimens in the Metastatic Setting
This is a randomized, multi-center, multinational, open-label, active-controlled, parallel design study of the combination of neratinib plus capecitabine versus the combination of lapatini...
This is a world wide phase 1/2, open-label, study of neratinib in combination with capecitabine, conducted in 2 parts. In Part 1, 3 to 9 subjects with solid tumors will be enrolled in eac...
This is a Phase III, randomized, multicenter, international, two-arm, open-label clinical trial designed to compare the safety and efficacy of T-DM1 with that of capecitabine + lapatinib f...
This is an open-label, phase 1 study of ascending single cohort of neratinib (HKI-272) combination with capecitabine.
This study will compare the anti-tumor efficacy of apricoxib and lapatinib/capecitabine with placebo and lapatinib/capecitabine as measured by time to disease progression and evaluate urin...
Capecitabine and S-1 are orally administered fluorinated pyrimidines with high-level activity against metastatic breast cancer (MBC). This randomized, multicenter, phase II study compared the activiti...
Abstract We report a case of phenytoin intoxication caused by an interaction between phenytoin and capecitabine. A 41-year-old woman was started on phenytoin (200 mg p.o. daily) for convulsive attacks...
ERBB2/HER2 belongs to the EGFR-family of receptor tyrosine kinases and its overexpression can promote tumor progression. Breast cancer patients with ERBB2 amplifications are currently treated with lap...
We aimed to the addition of synthetic 3-hydroxy-3-methyglutaryl coenzyme A (HMG-CoA) reductase inhibitor, simvastatin to capecitabine-cisplatin (XP) in patients with previously untreated advanced gast...
Medical and Biotech [MESH] Definitions
An antineoplastic agent that is a derivative of progesterone and used to treat advanced breast cancer.
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
An aromatase inhibitor that produces a state of "medical" adrenalectomy by blocking the production of adrenal steroids. It also blocks the conversion of androgens to estrogens. Aminoglutethimide has been used in the treatment of advanced breast and prostate cancer. It was formerly used for its weak anticonvulsant properties. (From Martindale, The Extra Pharmacopoeia, 30th ed, p454)
Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
