ব্যবহার

Elacestrant is an estrogen receptor antagonist indicated for: treatment of postmenopausal women or adult men, with ERpositive, HER2-negative, ESR1-mutated advanced or metastatic breast cancer with disease progression following at least one line of endocrine therapy.

ফার্মাকোলজি

Elacestrant is an estrogen receptor antagonist that binds to estrogen receptor-alpha (ERα). In ERpositive (ER+) HER2-negative (HER2-) breast cancer cells, elacestrant inhibited 17β-estradiol mediated cell proliferation at concentrations inducing degradation of ERα protein mediated through proteasomal pathway. Elacestrant demonstrated in vitro and in vivo antitumor activity including in ER+ HER2- breast cancer models resistant to fulvestrant and cyclin-dependent kinase 4/6 inhibitors and those harboring estrogen receptor 1 gene (ESR1) mutations.

সেবনবিধি

Patient Selection: Select patients for treatment of ER-positive, HER2-negative advanced or metastatic breast cancer withElacestrant based on the presence of ESR1 mutation(s) in plasma specimen using an FDA-approved test.Recommended Dosage: The recommended dosage of Elacestrant is 345 mg taken orally with food once daily until disease progression or unacceptable toxicity occurs.

সতর্কতা

Dyslipidemia: Hypercholesterolemia and hypertriglyceridemia occurred in patients taking Elacestrant at an incidence of 30% and 27%, respectively. The incidence of Grade 3 and 4 hypercholesterolemia and hypertriglyceridemia were 0.9% and 2.2%, respectively.Embryo-Fetal Toxicity: Based on findings in animals and its mechanism of action, Elacestrant can cause fetal harm when administered to a pregnant woman. Administration of elacestrant to pregnant rats resulted in adverse developmental outcomes, including embryo-fetal mortality and structural abnormalities, at maternal exposures below the recommended dose based on area under the curve (AUC). Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with Elacestrant and for 1 week after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with Elacestrant and for 1 week after the last dose.

গর্ভাবস্থায় ও স্তন্যদানকালে ব্যবহার

Based on findings in animals and its mechanism of action, Elacestrant can cause fetal harm when administered to a pregnant woman. There are no available human data on Elacestrant use in pregnant women to inform the drug-associated risk. There are no data on the presence of elacestrant in human milk, its effects on milk production, or the breastfed child. Because of the potential for serious adverse reactions in the breastfed child, advise lactating women to not breastfeed during treatment with Elacestrant and for 1 week after the last dose.

সংরক্ষণ
