Primary outcomePrimary: Progression-Free Survival (PFS) — 2.0; 3.1 months
Summary
The purpose of this study is to determine whether IMC-A12 offers increased progression-free survival (PFS) associated with IMC-A12 monotherapy and IMC-A12 in combination with an antiestrogen therapy in patients with hormone receptor positive advanced or metastatic breast cancer that have experienced disease progression on antiestrogen therapy.

Eligibility Criteria
Inclusion Criteria
- The patient has histologically or cytologically-confirmed invasive breast cancer, which at the time of study entry is either stage III (locally advanced) disease not amenable to curative therapy or stage IV disease. Histological confirmation of recurrent/metastatic disease is not required if clinical evidence of stage IV disease recurrence is available
- Tumors are positive for estrogen receptors (ER), progesterone receptors (PgR), or both (ie, 10% or more of infiltrating cancer cells exhibit nuclear staining for ER and/or PgR; positive biochemical test results are also acceptable)
- The patient has received prior antiestrogen therapy:
- With at least one antiestrogen agent (with or without ovarian suppression) administered for ≥ 3 months in the adjuvant or metastatic setting; and
- Experienced disease progression while on or within 12 months after receiving the last dose of endocrine therapy
- The patient is postmenopausal and/or meets at least one of the following criteria:
- Age ≥ 18 years with an intact uterus and amenorrhea for ≥ 12 months, with estradiol and/or follicle-stimulating hormone (FSH) values in the postmenopausal range
- History of bilateral oophorectomy
- History of bilateral salpingo-oophorectomy
- History of radiation castration and amenorrheic for ≥ 3 months
- The patient has fasting serum glucose < 120 mg/dL or below the ULN
Exclusion Criteria
- The patient has received more than two regimens of prior chemotherapy in the metastatic (or locally advanced and inoperable breast cancer) and adjuvant setting
- The patient has poorly controlled diabetes mellitus. Patients with a history of diabetes mellitus are allowed to participate, provided that their blood glucose is within normal range (fasting glucose at study entry < 120 mg/dL or below ULN) and that they are on a stable dietary and/or therapeutic regimen for this condition
- The patient is known to be positive for infection with the human immunodeficiency virus
