Important Safety Information and Indication
AROMASIN® (exemestane tablets) is contraindicated in patients with known hypersensitivity to the drug or to any of the excipients and in women who are premenopausal, pregnant, or who may become pregnant; the patient should be apprised of the potential hazard to the fetus.
AROMASIN should not be co-administered with estrogen-containing agents as these could interfere with its pharmacologic action.
Reductions in bone mineral density (BMD) over time are seen with AROMASIN use. Clinical fractures were reported in 4.2% of patients receiving AROMASIN and in 3.1% of patients receiving tamoxifen. Therefore, women with osteoporosis or at risk of osteoporosis should have their BMD formally assessed at the commencement of adjuvant treatment with exemestane. Patients treated with exemestane should be carefully monitored for BMD loss and treatment for osteoporosis should be initiated as appropriate.
Prior to initiation of aromatase inhibitor treatment, a routine assessment of 25-hydroxy vitamin D levels should be performed due to the high prevalence of Vitamin D deficiency in women with early breast cancer (EBC). Women with vitamin D deficiency should receive supplementation with vitamin D.
Adverse Events (AEs):
AROMASIN was generally well tolerated and adverse events were usually mild to moderate.
Early breast cancer: AEs occurring in ≥10% of patients in any treatment group (AROMASIN vs tamoxifen) were hot flushes (21.2% vs 19.9%), fatigue (16.1% vs 14.7%), arthralgia (14.6% vs 8.6%), headache (13.1% vs 10.8%), insomnia (12.4% vs 8.9%), and increased sweating
(11.8% vs 10.4%). Discontinuation rates due to AEs were similar between AROMASIN and tamoxifen. The incidence of cardiac ischemic events (myocardial infarction, angina, and myocardial ischemia) were 1.6% with AROMASIN, and 0.6% with tamoxifen. The incidence of cardiac failure was 0.4% with AROMASIN, and 0.3% with tamoxifen.
Advanced breast cancer: The most common AEs (AROMASIN vs megestrol acetate) were hot flushes (13% vs 5%), nausea (9% vs 5%), fatigue (8% vs 10%), increased sweating (4% vs 8%), and increased appetite
(3% vs 6%).
Dose modification is recommended for patients co-medicated with a potent CYP 3A4 inducer such as rifampin, phenytoin, carbamazepine, phenobarbital, or St John's wort.
The safety of chronic dosing in patients with moderate or severe hepatic or renal impairment has not been studied.
IndicationAROMASIN is indicated for:
the adjuvant treatment of postmenopausal women with estrogen-receptor positive early breast cancer who have received 2 to 3 years of tamoxifen and are switched to AROMASIN for completion of a total of 5 consecutive years of adjuvant hormonal therapy.
the treatment of advanced breast cancer in postmenopausal women whose disease has progressed following tamoxifen therapy.
