ARIMIDEX® (anastrozole) tablets for oral administration contain 1 mg of anastrozole, a non-steroidal aromatase inhibitor.
ARIMIDEX is indicated for adjuvant treatment of postmenopausal women with hormone receptor positive early breast cancer.
The effectiveness of ARIMIDEX in early breast cancer is based on an analysis of recurrence-free survival in patients treated for a median of 31 months (see CLINICAL PHARMACOLOGY
-- Clinical Studies subsection). Further follow-up of study patients will be required to determine long-term outcomes.
ARIMIDEX is indicated for the first-line treatment of postmenopausal women with hormone receptor positive or hormone receptor unknown locally advanced or metastatic breast cancer.
ARIMIDEX is indicated for the treatment of advanced breast cancer in postmenopausal women with disease progression following tamoxifen therapy. Patients with ER-negative disease and patients who did not respond to previous tamoxifen therapy rarely responded to ARIMIDEX.

Published Studies Related to Arimidex (Anastrozole)
Lipid profiles within the SABRE trial of anastrozole with and without
Lipid profiles in women with early breast cancer receiving anastrozole with or
without risedronate were examined within an international Phase III/IV study to
assess for possible treatment related changes. Postmenopausal women with hormone
receptor-positive breast cancer were assigned to 1 of 3 strata by risk of
Weight change associated with anastrozole and tamoxifen treatment in
postmenopausal women with or at high risk of developing breast cancer. 
Weight gain is commonly reported by breast cancer patients on tamoxifen or
aromatase inhibitors. Since weight gain may impact on outcome and compliance we
have prospectively assessed the effects of these agents on weight change in three
randomised trials for the treatment or prevention of breast cancer...

Randomized phase II neoadjuvant comparison between letrozole, anastrozole, and exemestane for postmenopausal women with estrogen receptor-rich stage 2 to 3 breast cancer: clinical and biomarker outcomes and predictive value of the baseline PAM50-based intrinsic subtype--ACOSOG Z1031. [2011.06.10]
PURPOSE: Preoperative aromatase inhibitor (AI) treatment promotes breast-conserving surgery (BCS) for estrogen receptor (ER)-positive breast cancer. To study this treatment option, responses to three AIs were compared in a randomized phase II neoadjuvant trial designed to select agents for phase III investigations... CONCLUSION: Neoadjuvant AI treatment markedly improved surgical outcomes. Ki67 and PEPI data demonstrated that the three agents tested are biologically equivalent and therefore likely to have similar adjuvant activities. LumA tumors were more likely to have favorable biomarker characteristics after treatment; however, occasional paradoxical increases in Ki67 (12% of tumors with > 5% increase after therapy) suggest treatment-resistant cells, present in some LumA tumors, can be detected by post-treatment profiling.
