Alisertib and Fulvestrant in Treating Patients With Hormone Receptor Positive Breast Cancer That is Metastatic or Locally Advanced and Cannot Be Removed by Surgery

Study Overview
=================
Brief Summary
-----------------
This phase I trial studies the side effects and best dose of alisertib when given together with fulvestrant in treating patients with hormone positive breast cancer that has spread to other parts of the body or has spread from where it started to nearby tissue or lymph nodes and cannot be removed by surgery. Alisertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Estrogen and progesterone are type of hormones made by the body and they can cause the growth of breast cancer cells. Hormone therapy using fulvestrant may fight breast cancer by lowering the amount of estrogen or progesterone the body makes. Giving alisertib together with fulvestrant may be a better treatment for breast cancer.

Detailed Description
-----------------
PRIMARY OBJECTIVES: I. To determine the maximally tolerated dose of alisertib in combination with fulvestrant. SECONDARY OBJECTIVES: I. To describe the safety and tolerability of alisertib in combination with fulvestrant. II. To examine tumor response in postmenopausal women treated with alisertib in combination with fulvestrant. TERTIARY OBJECTIVES: I. To assess aurora A kinase expression in archived breast cancer tissue biospecimens of participants, and to describe levels in those who do or do not experience dose-limiting toxicities (DLTs) or objective response. OUTLINE: This is a dose-escalation study of alisertib. Patients receive fulvestrant intramuscularly (IM) on day 1 (days 1 and 15 of course 1 only) and alisertib orally (PO) twice daily (BID) on days 1-3, 8-10, and 15-17. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 1 month.

NOTE: patients known to be HIV positive, but without clinical evidence of an immunocompromised state, are eligible for this trial Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm Other active malignancy =< 5 years prior to registration;

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum tolerated dose (MTD) of alisertib in combination with fulvestrant graded according to National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 | The MTD is defined as the highest dose level among those under consideration where at most 1 of 6 patients develops a dose limiting toxicity and 2 or more of the 3-6 patients treated at the next higher dose level develop a dose limiting toxicity. The maximum grade of each type of toxicity will be recorded for each patient. For each toxicity reported by dose level, the percentage of patients developing any degree of that toxicity as well as the percentage of patients developing a severe degree (grade 3 or higher) will be determined. | 28 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Tumor response (complete or partial response) using Response Evaluation Criteria in Solid Tumors version 1.1 | The number of confirmed tumor response will be tabulated for each dose level. | Up to 1 month post-treatment |
