Definitions
- GnRH receptor antagonists in the treatment of subjects suffering from, for example, endometriosis, uterine fibroids, polycystic ovary syndrome (PCOS), or adenomyosis.
- PCOS polycystic ovary syndrome
- adenomyosis BACKGROUND
- An orally-administered, nonpeptide small molecule competitive GnRH receptor antagonist, elagolix has recently been approved for the management of moderate to severe pain associated with endometriosis. Elagolix is currently in development for the management of heavy menstrual bleeding associated with uterine fibroids.
- Bupropion is an antidepressant of the aminoketone class that may be used for the treatment of major depressive disorder (MDD), for the prevention of seasonal affective disorder (SAD), and as an aid for smoking cessation treatment.
- MDD major depressive disorder
- SAD seasonal affective disorder
- Bupropion is primarily metabolized to hydroxybupropion by CYP2B6. Therefore, the potential exists for drug interactions between bupropion and drugs that are inhibitors or inducers of CYP2B6.
- Omeprazole a substituted benzimidazole
- Omeprazole is a proton pump inhibitor that inhibits gastric acid secretion.
- Omeprazole is metabolized via multiple pathways with CYP2C19- mediated formation of 5-hydroxyomeprazole and CYP3A-mediated formation of omeprazole sulfone being the main pathways responsible for omeprazole elimination. Therefore, the potential exists for drug interactions between omeprazole and drugs that are inhibitors or inducers of CYP2C19 and/or CYP3A.
- this disclosure provides a method for treating a gynecological disorder in a patient in need thereof.
- the method comprises orally administering to the patient sodium 4-( ⁇ (1R)-2-[5-(2-fluoro-3-methoxyphenyl)-3- ⁇ [2-fluoro-6- (trifluoromethyl)phenyl]methyl ⁇ -4-methyl-2,6-dioxo-3,6-dihydropyrimidin-1(2H)-yl]-1- phenylethyl ⁇ amino)butanoate (“elagolix sodium”), wherein the patient concomitantly receives treatment with a CYP2B6 substrate.
- the CYP2B6 substrate is bupropion.
- elagolix sodium is orally administered to the patient according to a recommended elagolix dosing schedule.
- the recommended elagolix dosing schedule comprises twice daily oral administration of elagolix sodium in an amount equivalent to 300 mg of elagolix free acid to achieve a total daily dose equivalent to 600 mg of elagolix free acid.
- concomitant administration of the CYP2B6 substrate and elagolix sodium according to the recommended elagolix dosing schedule results in an altered CYP2B6 substrate pharmacokinetic parameter relative to the CYP2B6 substrate pharmacokinetic parameter as obtained for administration of the CYP2B6 substrate alone.
- concomitant administration of a CYP2B6 substrate and elagolix sodium according to a recommended elagolix dosing schedule may result in an increased Cmax for the CYP2B6 substrate and/or a metabolite thereof relative to the C max for the CYP2B6 substrate and/or a metabolite thereof obtained following administration of bupropion alone.

- Table 1 Subject Demographic Characteristics a Arithmetic Mean ⁇ standard deviation (range)
- Methods In a single-sequence, two-period study, healthy women received single oral doses of 150 mg bupropion (extended-release tablets) in the morning on day 1 in period 1 and on day 11 in period 2. Elagolix 300 mg BID (as 300 mg immediate release tablets) was administered in the morning and evening on days 1 through 14 in period 2. The study design is shown in Figure 1.
- the doses of bupropion and elagolix were taken orally in the morning after at least an 8-hour fast with approximately 240 mL of water, breakfast was consumed 2 hours after dosing. No food was consumed for 2 hours prior to the evening doses of elagolix continuing through 2 hours after. The doses of elagolix were separated by approximately 12 hours. [00109] Intensive PK sampling was performed for bupropion (parent) and OH-bupropion (metabolite) when bupropion dosed alone and with elagolix. [00110] Plasma concentrations of bupropion, OH-bupropion, and elagolix were determined using validated liquid chromatography methods with tandem mass spectrometric detection.
- Example 2 Co-administration with a CYP2C19 substrate.
- DPI drug-drug interaction
- the objective of this study was to evaluate the effect of multiple doses of elagolix sodium on the pharmacokinetics of omeprazole and its metabolites using a single-arm study design in adult healthy premenopausal female subjects.
- Subjects Twenty adult premenopausal female subjects were enrolled in the study. All subjects completed the study and were included in the analyses (Table 3). [00124] Table 3.
- omeprazole On Day 11, subjects received elagolix 300 mg BID and a single dose of omeprazole 40 mg under fasting conditions. Doses of elagolix were separated by approximately 12 hours.
- omeprazole Pharmacokinetic parameters for omeprazole, 5-hydroxyomeprazole and omeprazole sulfone were estimated including Cmax, Tmax, AUCt and AUCinf, as well as t1/2. Additionally, the metabolite-to-parent (M:P) AUC ratios were calculated for both metabolites compared to omeprazole. [00129] Testing was performed for CYP2C19 variants including the *2 (rs4244285), *3 (rs4986893), *4 (rs28399504), *8 (rs41291556), *10 (rs6413438) and *12 (rs55640102) alleles.

- M:P AUC ratios the central value ratios as well as the point estimates and 90% confidence intervals for the Day 11 versus Day 1 comparison are presented in Table 5.
- Table 5 Comparison of Metabolite-to-Parent AUC Ratios for Omeprazole and its Metabolites with/without Elagolix Co-administration.
- Elagolix 300 mg BID dosing decreased the M:P AUC inf ratio for 5- hydroxyomeprazole by 60% and increase the M:P AUCinf ratio for omeprazole sulfone by only 25%.
- Twelve subjects were extensive metabolizers (EM) for CYP2C19, 5 were intermediate metabolizers (IM), and 3 were poor metabolizers (PM).
- EM extensive metabolizers
- IM intermediate metabolizers
- PM poor metabolizers
- the impact of elagolix co- administration on the pharmacokinetics of omeprazole and its metabolites is shown in Figure 6 for each CYP2C19 genotype.
- omeprazole exposures (AUCinf) by 2- to 2.5- fold in EM and IM subjects, but decreased omeprazole AUC inf by 40% in PMs.5- hydroxyomeprazole AUCinf decreased by 20-30% in all genotype subgroups, and omeprazole sulfone exposures increased by ⁇ 3-fold in EM and IM subjects.
- the regimens tested were generally well tolerated by the subjects in this study.
- Dose adjustments for concomitant therapy for a co-morbid condition for a given patient will depend on whether the patient is an extensive, intermediate or a poor metabolizer of CYP2C19.
- the objective of such dose adjustments would be to bring the AUC and Cmax of the elagolix and the CYP2C19 substrate (e.g. omeprazole) that is concomitantly administered to a patient (having a co-morbid condition who requires both), to be substantially similar to the observed AUC and Cmax, of the respective drugs, if the drug-drug interaction did not occur.
- the CYP2C19 substrate e.g. omeprazole
- ORIAHNN is a combination of elagolix, a gonadotropin-releasing hormone (GnRH) receptor antagonist, estradiol, an estrogen, and norethindrone acetate, a progestin, indicated for the management of heavy menstrual bleeding associated with uterine leiomyomas (fibroids) in premenopausal women.
- GnRH gonadotropin-releasing hormone
- ORIAHNN is dosed and administered as one capsule (elagolix 300 mg, estradiol 1 mg, norethindrone acetate 0.5 mg) in the morning and one capsule (elagolix 300 mg) in the evening for up to 24 months.
- DOSAGE FORMS AND STRENGTHS DOSAGE FORMS AND STRENGTHS
- ORIAHNN is presented as a Morning (AM) capsule having elagolix 300 mg, estradiol 1 mg, norethindrone acetate 0.5 mg and an Evening (PM) capsule having elagolix 300 mg.
- AM Morning
- PM Evening
- Elagolix is a weak to moderate inducer of cytochrome P450 (CYP3A).
- Co- administration with ORIAHNN may decrease plasma concentrations of drugs that are substrates of CYP3A.
- Elagolix is a weak inhibitor of CYP2C19. Co-administration with ORIAHNN may increase plasma concentrations of drugs that are substrates of CYP2C19 (e.g., omeprazole and esomeprazole) (see Table 6).
- Elagolix is an inhibitor of efflux transporter P-glycoprotein (P-gp). Co- administration with ORIAHNN may increase plasma concentrations of drugs that are substrates of P-gp (e.g., digoxin) (see Table 6).
- P-gp efflux transporter P-glycoprotein
- Co- administration with ORIAHNN may increase plasma concentrations of drugs that are substrates of P-gp (e.g., digoxin) (see Table 6).
- the effect of co-administration of ORIAHNN on concentrations of concomitant drugs and the clinical recommendations for these drug interactions are summarized in Table 6. Table
- Elagolix is a substrate of CYP3A, P-gp, and OATP1B1; estradiol and norethindrone acetate are metabolized partially by CYP3A.
- Concomitant use of ORIAHNN and strong CYP3A inducers may decrease elagolix, estradiol and norethindrone plasma concentrations and may result in a decrease in the therapeutic effects of ORIAHNN.
- the concomitant use of rifampin increased plasma concentrations of elagolix. Concomitant use of ORIAHNN and rifampin is not recommended.
- Concomitant use of ORIAHNN and strong CYP3A inhibitors e.g., ketoconazole, grapefruit juice
- ORIAHNN may increase elagolix, estradiol and norethindrone plasma concentrations and increase the risk of adverse reactions.
- Co-administration of ORIAHNN with drugs that inhibit OATP1B1 may increase elagolix plasma concentrations.
- Concomitant use of ORIAHNN and strong OATP1B1 inhibitors e.g., cyclosporine ) is contraindicated.
- Example 4 [00158] USE OF ORIAHNN IN SPECIFIC POPULATIONS [00159] Pregnancy [00160] Risk Summary [00161] Use of ORIAHNN is contraindicated in pregnant women. Exposure to elagolix early in pregnancy may increase the risk of early pregnancy loss.
- the exposure margins were 25 and 7 times the MRHD for the rat and rabbit, respectively.
- GnRH gonadotropin-releasing hormone
- the rat study is unlikely to identify pharmacologically mediated effects of elagolix on embryofetal development.
- the rat study is still expected to provide information on potential non-target-related effects of elagolix.
- elagolix was given in the diet to achieve doses of 0, 100 and 300 mg/kg/day (25 per dose group) from gestation day 6 to lactation day 20.
- ORIAHNN may delay the ability to recognize the occurrence of a pregnancy because it may reduce the intensity, duration and amount of menstrual bleeding. Exclude pregnancy before initiating treatment with ORIAHNN. Perform pregnancy testing if pregnancy
- Drug Interactions Change in Pharmacokinetics of Co-administered Drug in the Presence of Elagolix [00191] No clinically significant changes in sertraline, fluconazole, bupropion, or transdermal patch E2/NETA 0.51/4.8 mg exposures were observed when co-administered with elagolix 300 mg twice daily [00192] Pharmacogenomics [00193] Hepatic uptake of elagolix involves the OATP1B1 transporter protein.
