Drug Interaction | Drug Names |
---|---|
Elacestrant/Strong and Moderate CYP3A4 Inducers SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Elacestrant is metabolized by CYP3A4. Strong and moderate inducers of CYP3A4 may increase the metabolism of elacestrant.(1) CLINICAL EFFECTS: Concurrent use of a strong or moderate inducer of CYP3A4 may result in decreased levels and effectiveness of elacestrant.(1) PREDISPOSING FACTORS: Induction effects may be more likely with regular use of the inducer for longer than 1-2 weeks. PATIENT MANAGEMENT: Avoid concomitant use of elacestrant with strong or moderate CYP3A4 inducers.(1) DISCUSSION: Coadministration of 200 mg dose of elacestrant with rifampin (a strong CYP3A inducer) decreased the maximum concentration (Cmax) and area-under-curve (AUC) of elacestrant by 73% and 86%, respectively.(1) Efavirenz is predicted to decrease the Cmax and AUC of elacestrant by 44 to 63% and 55% to 73%, respectively.(1) Strong inducers of CYP3A4 include: apalutamide, barbiturates, carbamazepine, encorafenib, enzalutamide, fosphenytoin, ivosidenib, lumacaftor, mitotane, phenobarbital, phenytoin, primidone, rifampin, rifapentine, and St. John's wort.(2,3) Moderate inducers of CYP3A4 include: belzutifan, bosentan, cenobamate, dabrafenib, dipyrone, efavirenz, elagolix, etravirine, lesinurad, lorlatinib, mavacamten, mitapivat, modafinil, nafcillin, pacritinib, pexidartinib, repotrectinib, rifabutin, sotorasib, telotristat, thioridazine, and tovorafenib.(2,3) |

Elacestrant/Strong and Moderate CYP3A4 Inhibitors SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Inhibitors of CYP3A4 may inhibit the metabolism of elacestrant.(1) CLINICAL EFFECTS: Concomitant use of a strong or moderate CYP3A4 inhibitor increases elacestrant plasma concentrations, which may increase the incidence and severity of adverse reactions.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Avoid concomitant use of strong or moderate CYP3A4 inhibitors with elacestrant.(1) DISCUSSION: Coadministration of itraconazole (a strong CYP3A4 inhibitor) increased elacestrant area-under-curve (AUC) and maximum concentration (Cmax) by 5.3-fold and 4.4-fold, respectively.(1) Coadministration of fluconazole (a moderate CYP3A4 inhibitor) is predicted to increase elacestrant AUC and Cmax by 2.3-fold and 1.6-fold, respectively.(1) Strong inhibitors of CYP3A4 include: adagrasib, boceprevir, ceritinib, clarithromycin, cobicistat, idelalisib, indinavir, itraconazole, josamycin, ketoconazole, levoketoconazole, lonafarnib, lopinavir, mibefradil, mifepristone, nefazodone, nelfinavir, nirmatrelvir, paritaprevir, posaconazole, ribociclib, saquinavir, telaprevir, telithromycin, tipranavir, troleandomycin, tucatinib, and voriconazole.(2) Moderate CYP3A4 inhibitors include: amprenavir, aprepitant, atazanavir, avacopan, berotralstat, clofazimine, conivaptan, crizotinib, darunavir, diltiazem, dronedarone, duvelisib, erythromycin, fedratinib, fluconazole, fluvoxamine, fosamprenavir, fosnetupitant, imatinib, isavuconazonium, oral lefamulin, lenacapavir, letermovir, netupitant, nilotinib, nirogacestat, schisandra, tofisopam, treosulfan, verapamil, and voxelotor.(2) |

Fluoroestradiol F-18/Estrogen Receptor Blockers (ERBs) SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Drugs that bind to the estrogen receptor (ER) may compete with the binding of radioactive diagnostic agent fluoroestradiol F-18.(1) CLINICAL EFFECTS: Concurrent use of estrogen receptor blockers such as selective estrogen receptor modulators (SERMs) and selective estrogen receptor down-regulators (SERDs) may reduce the detection of ER-positive lesions with fluoroestradiol F-18.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Before administering fluoroestradiol F-18, discontinue drugs that bind to the ER, such as SERMs and SERDs, for at least 5 biological half-lives.(1) The following washout periods apply when discontinuing ERBs, prior to fluoroestradiol F-18 administration: - Bazedoxifene = 7 days - Clomiphene = 25 days - Elacestrant = 11 days - Fulvestrant = 28 weeks - Ospemifene = 5 days - Raloxifene = 7 days - Tamoxifen = 8 weeks - Toremifene = 5 weeks DISCUSSION: The following ERBs are linked to this monograph: SERDs: elacestrant and fulvestrant. SERMs: bazedoxifene, clomiphene, ospemifene, raloxifene, tamoxifen and toremifene. |

Elacestrant use during pregnancy can cause fetal harm based on findings in an animal study and the mechanism of action of the drug. Human data on elacestrant use during pregnancy are not available to determine the drug-associated risk. Administration of oral elacestrant to pregnant rats during the period of organogenesis resulted in structural abnormalities and embryofetal death at maternal exposures below the recommended dose based on AUC.
Maternal toxicity (reduced weight gain, low food consumption, red vulvar discharge) was also observed in rats. Verify pregnancy status in females of reproductive potential prior to initiating elacestrant. Apprise patients of the potential hazard to the fetus if elacestrant is used during pregnancy.
Maternal toxicity (reduced weight gain, low food consumption, red vulvar discharge) was also observed in rats. Verify pregnancy status in females of reproductive potential prior to initiating elacestrant. Apprise patients of the potential hazard to the fetus if elacestrant is used during pregnancy.
It is unknown whether elacestrant distributes into human milk, or affects milk production or the breast-fed infant. Because of the potential for serious adverse reactions in breast-fed infants, advise women to not breast-feed during treatment with elacestrant and for 1 week after the last dose.
In the EMERALD trial, 43 and 17% of patients were >=65 and >=75 years of age. There were no overall differences in the safety or efficacy of elacestrant between patients >=65 years and younger adults. There was an insufficient number of patients >=75 years of age to assess age-related differences in safety or efficacy. No clinically important differences in elacestrant pharmacokinetics were observed based on age (range 24-89 years).
