A Phase I Trial to Evaluate the Safety of the Addition of Alisertib to Fulvestrant in Women With Advanced Hormone Receptor Positive (HR+) Breast Cancer

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.

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.

Inclusion Criteria:

- Histologic proof of metastatic or locally advanced, unresectable breast cancer which
is estrogen receptor positive and/or progesterone positive per institutional standards

- Ability to provide informed written consent

- Willing to return to enrolling institution for follow-up (during the active monitoring
phase of the study)

- Life expectancy >= 4 months

- Willing to provide tissue samples for research purposes

- Prior therapies:

- All women: at least one prior line of hormonal therapy for de novo disease (stage
IV metastatic at diagnosis, no prior adjuvant therapy) or relapse > 1 year after
completion of adjuvant therapy; relapse on adjuvant hormonal therapy will count
as the one prior line of therapy

- All women: at least 1 prior line of chemotherapy in the adjuvant and/or
metastatic setting, but not more than 2 regimens in the metastatic setting

- Capable of swallowing tablets

Exclusion Criteria:

- Known standard therapy for the patient's disease that is potentially curative or
definitely capable of extending life expectancy

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements

- Any of the following prior therapies:

- Chemotherapy =< 21 days prior to registration

- Mitomycin C/nitrosoureas =< 42 days prior to registration

- Immunotherapy =< 28 days prior to registration

- Biologic therapy =< 28 days prior to registration

- Radiation therapy =< 21 days prior to registration

- Radiation to > 25% of bone marrow prior to registration

- Hormonal therapy =< 14 days prior to registration

- Failure to recover to grade =< 1 from acute, reversible effects of prior chemotherapy
regardless of interval since last treatment

- Uncontrolled central nervous system (CNS) metastases

- NOTE: metastases have been treated by surgery and/or radiotherapy and patients
have been neurologically stable and off of steroids > 12 weeks are eligible

- Other concurrent chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy
considered investigational (utilized for a non-Food and Drug Administration
[FDA]-approved indication and in the context of a research investigation)

- Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment
of the investigator, would make the patient inappropriate for entry into this study or
interfere significantly with the proper assessment of safety and toxicity of the
prescribed regimens

- Immunocompromised patients and patients known to be human immunodeficiency virus (HIV)
positive and currently receiving antiretroviral therapy; 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; EXCEPTIONS: non-melanotic
skin cancer or carcinoma-in-situ of the cervix; NOTE: patients must not be receiving
other active treatment for another cancer

- History of myocardial infarction =< 6 months prior to registration, or congestive
heart failure requiring use of ongoing maintenance therapy for life-threatening
ventricular arrhythmias

pan-aurora kinase inhibitor)

permitted from the day prior (day -1) through to the end of alisertib dosing (e.g.,
day 7), except as required for premedication for a protocol-specific agent (e.g.,
taxane); neutralizing antacids and calcium-containing supplements cannot be taken from
2 hours prior to alisertib dosing until up to 2 hours after dosing
