MK2206 in Combination With Anastrozole, Fulvestrant, or Anastrozole and Fulvestrant in Treating Postmenopausal Women With Metastatic Breast Cancer
A Phase 1 Trial of MK-2206 in Combination With Anastrozole, Fulvestrant, or Anastrozole Plus Fulvestrant in Postmenopausal Women With Estrogen Receptor Positive Metastatic Breast Cancer

This phase I trial studies the side effects and the best dose of MK 2206 (Akt inhibitor MK2206) when given with anastrozole, fulvestrant, or anastrozole and fulvestrant in treating postmenopausal women with breast cancer that has spread to other parts of the body. Estrogen can cause the growth of breast cancer cells. Hormone therapy using anastrozole or fulvestrant may fight breast cancer by lowering the amount of estrogen the body makes. Akt inhibitor MK2206 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving Akt inhibitor MK2206 together with anastrozole, fulvestrant, or anastrozole and fulvestrant may kill more tumor cells.

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of MK-2206 in combination with anastrozole based on toxicities observed during cycle 1 therapy. (Phase IA) II. To evaluate the tolerability of prolonged administration (3 months) of MK-2206 in combination with anastrozole at the MTD defined in Phase IA. (Phase IB) III. To determine the recommended phase II treatment dosing (RPTD) of MK-2206 in combination with anastrozole based on toxicities observed with prolonged drug administration. (Phase IB) IV. To determine the tolerability of fulvestrant (Arm C), or fulvestrant plus anastrozole (Arm D), respectively, in combination with MK-2206 (at the RPTD defined in Phase 1B). (Arms C and D) V. To determine the recommended phase II treatment dose (RPTD) of fulvestrant (Arm C) or fulvestrant plus anastrozole (Arm D), respectively, in combination with MK-2206 based on toxicities observed with prolonged drug administration (3 months). (Arms C and D) VI. To evaluate the toxicity profile of MK-2206 in combination with fulvestrant (Arm C) or fulvestrant plus anastrozole (Arm D), respectively, with prolonged drug administration. (Arms C and D)

SECONDARY OBJECTIVES:

I. To evaluate the toxicity profile of MK-2206 in combination with anastrozole, or fulvestrant, or anastrozole plus fulvestrant.

II. To evaluate the clinical benefit rate (CBR: complete response [CR]+partial response [PR]+stable disease [SD] > 6 months), response rate (CR+PR), and percent of patients progression free at 6 months with the treatment of MK-2206 in combination with anastrozole, or fulvestrant or anastrozole plus fulvestrant in patients with estrogen receptor positive (ER+) metastatic breast cancer.

III. To examine serum levels of estradiol prior to and following 1 cycle of MK-2206 therapy.

TERTIARY OBJECTIVES:

I. To examine baseline tumor specimens for phosphatidylinositol 3 kinase (PI3K) pathway abnormalities and to explore its relationship with treatment response.

II. To evaluate the effect of MK-2206 on tumor cell v-akt murine thymoma viral oncogene homolog 1 (AKT) signaling, proliferation, and apoptosis using serially collected tumor samples in available cases.

III. To examine changes in tumor cell glucose uptake by positron emission tomography (PET) with 2-[18F]fluoro-2-deoxy-D-glucose (FDG) at baseline and 24 h post day 1 MK-2206. (Phase IA) IV. To examine the phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) mutation status in circulating deoxyribonucleic acid (DNA) at baseline and following study therapy and to correlate with tumor tissue PIK3CA status and treatment response.

ARM B: The RPTD of Akt inhibitor MK2206 with anastrozole is determined after 3 courses, administered as in Arm A.

ARM C: Patients receive Akt inhibitor MK2206 PO on days 1, 8, 15, and 22, fulvestrant intramuscularly (IM) on day 1 and day 15 of course 1 and then on day 1 of each course in each subsequent courses. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM D: Patients receive Akt inhibitor MK2206 PO as in Arm A, anastrozole PO on days 1-28 and fulvestrant IM on day 1. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up for 30 days.
