( 5.2 , 8.1 , 8.3 ) 5.1 QTc Interval Prolongation VEPPANU can cause QT (QTc) interval prolongation [see Clinical Pharmacology ( 12.2 )] . In VERITAC-2, QTc interval prolongation was reported in 10% of patients; Grade 3 occurred in 1.6% of patients. The heart-rate corrected QTc interval using Fridericia's method was greater than 500 msec in 1.6% of patients, and the increase from baseline QTc was greater than 60 msec in 2.6% of patients. VEPPANU dose reduction was required for 0.3% of patients due to QTc interval prolongation [see Adverse Reactions ( 6.1 )] . Correct electrolyte abnormalities, including hypokalemia and hypomagnesemia, prior to and during treatment with VEPPANU. Perform an ECG prior to initiation of treatment with VEPPANU, and do not initiate VEPPANU in patients with QTc > 470 msec. Repeat ECG approximately 4 weeks after initiating treatment and as clinically indicated. In patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval, additional ECG monitoring may be necessary. Avoid concomitant use of VEPPANU with strong CYP3A inhibitors or drugs known to prolong the QTc interval. Reduce VEPPANU dose when concomitant use with strong CYP3A inhibitors cannot be avoided [see Dosage and Administration ( 2.4 ), Drug Interactions ( 7.1 , 7.3 ), and Clinical Pharmacology ( 12.2 )] . If concomitant use with other QTc-prolonging agents cannot be avoided, increase the frequency of ECG monitoring. Withhold, reduce dose, or permanently discontinue based on severity [see Dosage and Administration ( 2.3 )] . 5.2 Embryo-Fetal Toxicity Based on findings from animal studies and its mechanism of action, VEPPANU can cause fetal harm when administered to a pregnant woman. In an animal reproduction study, oral administration of vepdegestrant to pregnant rats during the period of organogenesis 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 VEPPANU and for 2 weeks after the last dose.

( 8.2 ) 8.1 Pregnancy Risk Summary Based on findings in animals and its mechanism of action, VEPPANU can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12.1 ) ]. There are no available human data on the use of VEPPANU in pregnant women to inform the drug-associated risk. In an animal reproduction study, oral administration of vepdegestrant to pregnant rats during the period of organogenesis caused adverse developmental outcomes, including embryo-fetal mortality and structural abnormalities at maternal exposures below the recommended dose based on AUC ( see Data ). Advise pregnant women and females of reproductive potential of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In an embryo-fetal development study in pregnant rats, administration of oral doses of vepdegestrant up to 300 mg/kg/day during the period of organogenesis resulted in embryo-fetal mortality (increased resorptions, post-implantation loss and reduced number of live fetuses) at ≥30 mg/kg/day (approximately 0.3 times the human AUC at the recommended dose). Additional adverse effects at ≥30 mg/kg/day included reduced fetal weight and skeletal abnormalities including delays in skeletal ossification (reduced number of ossification sites, incompletely ossified cervical arches or thoracic centra), skeletal malformations (fusion of sacral centra, hemivertebrae of the sacrum), and/or increased incidence of fetal variations (short cervical ribs, misaligned caudal vertebrae, misshapen cervical arches, and misaligned sacral vertebrae). 8.2 Lactation Risk Summary There are no data on the presence of vepdegestrant or its metabolites in human milk, or its effects on milk production or the breastfed child. Because of the potential for serious adverse reactions in the breastfed child, advise lactating women not to breastfeed during treatment with VEPPANU and for 2 weeks after the last dose. 8.3 Females and Males of Reproductive Potential VEPPANU can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . Pregnancy Testing Verify the pregnancy status in females of reproductive potential prior to initiating VEPPANU treatment. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with VEPPANU and for 2 weeks after the last dose. Males Advise male patients with female partners of reproductive potential to use effective contraception during treatment with VEPPANU and for 2 weeks after the last dose. Infertility Based on findings from animal studies, VEPPANU may impair fertility in females and males of reproductive potential. The effects of vepdegestrant on fertility were reversible in female animals [see Nonclinical Toxicology ( 13.1 )] . 8.4 Pediatric Use The safety and effectiveness of VEPPANU in pediatric patients have not been established. 8.5 Geriatric Use Of 313 patients who received VEPPANU in the VERITAC-2 study, 39% were 65 years of age or older and 13% were 75 years of age or older. No overall differences in safety or effectiveness of VEPPANU were observed between patients 65 years of age or older compared to younger patients. There is an insufficient number of patients 75 years of age or older to assess whether there are differences in safety or effectiveness." ], "description": [ "11 DESCRIPTION Vepdegestrant is a heterobifunctional protein degrader. It is a small molecule comprised of an estrogen receptor binding domain joined by a linker to an E3 ligase binding domain. The chemical name of vepdegestrant is 2,6-piperidinedione, 3-[1,3-dihydro-1-oxo-5-[4-[[1-[4-[(1 R ,2 S )-1,2,3,4-tetrahydro-6-hydroxy-2-phenyl-1-naphthalenyl]phenyl]-4-piperidinyl]methyl]-1-piperazinyl]-2 H -isoindol-2-yl]-, (3 S )-. The chemical structure of vepdegestrant is: Vepdegestrant is white to off-white to pale yellow solid with the molecular formula of C 45 H 49 N 5 O 4 and a molecular weight of 723.90 Daltons. Vepdegestrant solubility is pH dependent. The solubility ranges from freely soluble under gastric pH conditions to slightly soluble under intestinal pH conditions. VEPPANU is supplied as blue film-coated, immediate release tablets containing either 100 mg or 200 mg vepdegestrant together with: colloidal silicon dioxide, croscarmellose sodium, hypromellose, lactose monohydrate, microcrystalline cellulose, sodium stearyl fumarate, vitamin E-polyethylene glycol succinate, and Opadry ® QX Blue as inactive ingredients. Opadry ® QX Blue film-coating contains: FD&C Blue No. 2 (indigo carmine) aluminum lake, ferric oxide yellow (yellow iron oxide), ferrosoferric oxide (black iron oxide), glyceryl mono and dicaprylocaprate (glycerol monocaprylocaprate), polyvinyl alcohol, polyvinyl alcohol polyethylene glycol graft copolymer [macrogol poly (vinyl alcohol) grafted copolymer], talc, and titanium dioxide. chemstructure" ], "clinical_pharmacology": [ "12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Vepdegestrant is a heterobifunctional protein degrader that binds to estrogen receptor (ER) and the E3 ligase cereblon (CRBN). This interaction results in the degradation cascade through CRBN-mediated polyubiquitination and degradation of ER by the proteasome, leading to reduction of ER protein levels in breast cancer cells. Vepdegestrant induced degradation of wild-type (WT) and mutant ER, inhibited ER-dependent breast cancer cell line proliferation in vitro and demonstrated antitumor activity in vivo in both WT and mutant ESR1 breast cancer models. 12.2 Pharmacodynamics The exposure-response relationship and time-course of pharmacodynamic response of vepdegestrant have not been fully characterized. Cardiac Electrophysiology The largest mean increase in QTc interval was 12 ms (upper confidence interval = 15 ms) after administration of vepdegestrant at the recommended dosage of 200 mg once daily in patients with ESR1 mutation-positive breast cancer. 12.3 Pharmacokinetics Vepdegestrant pharmacokinetics were observed at steady state in patients with ER+/HER2- breast cancer at the approved recommended dosage of 200 mg once daily and are presented as mean (coefficient of variation (CV%)) unless otherwise specified. Vepdegestrant maximum concentration (C max ) is 926 ng/mL (39%), and the total systemic exposure (AUC) is 17,155 ng•hr/mL (36%). Vepdegestrant AUC and C max increase in an approximately dose proportional manner over the dose range of 100 mg (0.5 times the approved recommended dose) to 500 mg (2.5 times the approved recommended dose). Vepdegestrant accumulation is approximately 1.4-fold for AUC and 1.3-fold for C max . Vepdegestrant steady state is reached in approximately 7 days. Absorption Vepdegestrant median (min, max) time to maximum plasma concentration (T max ) is approximately 6 (4, 8) hours. Effect of Food Vepdegestrant AUC increased 2.9-fold and C max 3.2-fold following administration with a high-fat meal (approximately 800 to 1,000 calories; ≥50% fat). Distribution Vepdegestrant plasma protein binding is >99%. The apparent (oral) volume of distribution is 764 L (26%) following a single 200 mg dose. Elimination Vepdegestrant effective elimination half-life is 19 hours (50%) with an apparent (oral) clearance of 12 L/h (36%). Metabolism Vepdegestrant is primarily metabolized through direct sulfation via multiple SULT isoforms and oxidation via CYP3A4 and to a lesser extent by CYP2C8, CYP2C9 and CYP3A5. Unchanged total vepdegestrant represented 92% of total radioactivity in plasma. Excretion Following a single oral dose of radiolabeled vepdegestrant 200 mg to healthy subjects, approximately 68% of the dose was recovered in feces (18% unchanged) and 1.5% in urine (<0.02% unchanged). Specific Populations No clinically significant differences in the pharmacokinetics of vepdegestrant were observed based on age (26 to 89 years), sex, body weight (37 to 181 kg), race (60% White, 27% Asian, 2.2% Black or African American, and 10% other), CLcr 30 mL/min to 90 mL/min (estimated by Cockcroft Gault equation) or mild hepatic impairment (total bilirubin ≤ULN and AST>ULN or total bilirubin >1 to 1.5 × ULN and any AST). The effect of moderate hepatic impairment (total bilirubin >1.5 to 3 × ULN and any AST), severe hepatic impairment (total bilirubin > 3 × ULN and any AST), CLcr 15 to < 30 mL/min, and end-stage renal disease (CLcr < 15 mL/min) on the pharmacokinetics of vepdegestrant is unknown. Drug Interaction Studies Clinical Studies and Model-Informed Approaches Strong CYP3A Inhibitors : Vepdegestrant AUC increased 1.7-fold and C max 1.5-fold following concomitant use of itraconazole (strong CYP3A inhibitor) 200 mg once daily. Strong CYP3A Inducers: Vepdegestrant AUC decreased to 64% and C max to 80% following concomitant use of carbamazepine (strong CYP3A inducer) 200 mg three times daily. Acid Reducing Agents: Vepdegestrant AUC decreased to 84% and C max to 74% following concomitant use of esomeprazole (proton-pump inhibitor) 40 mg once daily. CYP3A Substrates : Midazolam (CYP3A substrate) AUC increased 1.7-fold and C max 1.2-fold following concomitant use of VEPPANU 200 mg once daily. P-gp Substrates : Dabigatran etexilate (P-gp substrate) AUC increased 2-fold and C max 1.9-fold following concomitant use of a single dose of VEPPANU 200 mg. Breast Cancer Resistance Protein (BCRP) Substrates : Rosuvastatin (BCRP substrate) AUC increased 1.2-fold and C max 1.2-fold following concomitant use of a single dose of VEPPANU 200 mg. UGT1A9 Substrates : Dapagliflozin (UGT1A9 index substrate) AUC is predicted to increase approximately 2-fold following multiple doses of VEPPANU. In vitro studies: CYP450 Enzymes: Vepdegestrant does not inhibit CYP1A2, CYP2C8, CYP2C9, CYP2C19 or CYP2D6 and does not induce CYP1A2, CYP2C8, CYP2C9, or CYP2C19.Vepdegestrant is an inhibitor of CYP2B6. UDP-Glucuronosyltransferases (UGT): Vepdegestrant does not inhibit UGT1A1, UGT1A4, UGT1A6, UGT2B7, or UGT2B15. Transporter Systems: Vepdegestrant is not a substrate of P-gp, BCRP, OATP1B1, or OATP1B3. Vepdegestrant does not inhibit MATE1, MATE2-K, OAT1, OAT3, OATP1B1, OATP1B3, or OCT2." ], "nonclinical_toxicology": [ "13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Vepdegestrant was not carcinogenic in a 6-month carcinogenicity study in rasH2 transgenic mice with daily oral administration of vepdegestrant up to 800 mg/kg/day. Mutagenesis Vepdegestrant was not mutagenic in an in vitro bacterial reverse mutation assay (Ames) or clastogenic in an in vitro human lymphocyte micronucleus assay or an in vivo rat micronucleus assay. Impairment of Fertility Fertility studies with vepdegestrant in animals have not been conducted. In repeat-dose toxicity studies up to 26 weeks duration in rats and 39 weeks duration in dogs, oral administration of vepdegestrant resulted in adverse female reproductive effects including atrophy of the uterus, oviduct, cervix and vagina and follicular cysts in rats at doses ≥30 mg/kg/day (0.3 times the human AUC at the recommended dose) and in dogs at doses ≥10 mg/kg/day (0.4 times the human AUC at the recommended dose). Additional findings in the ovary in rats included decreased corpora lutea and follicle hemorrhage at ≥30 mg/kg/day. Oral administration of vepdegestrant resulted in adverse male reproductive effects including decreased epididymis and prostate weights with decreased secretion and decreased secretion in the seminal vesicle in rats at doses ≥30 mg/kg/day, and seminiferous tubular degeneration, hypoplasia of seminiferous tubules, and epididymal epithelial cell necrosis in dogs at 90 mg/kg/day (approximately 2 times the human AUC at the recommended dose). The effects of vepdegestrant on female reproductive organs were reversible following a 4-week recovery period. The effects on male reproductive organs were not reversible following a 4-week recovery period. 13.2 Animal Toxicology and/or Pharmacology In a 6-month repeat-dose toxicity study, oral administration of vepdegestrant to rats resulted in granulosa cell hyperplasia in the ovary at 300 mg/kg/day (5 times the human AUC at the recommended dose). In a 9-month repeat-dose toxicity study, oral administration of vepdegestrant to dogs resulted in interstitial cell hypertrophy/hyperplasia in the testis at doses ≥10 mg/kg/day (0.4 times the human AUC at the recommended dose). Reversibility was not assessed." ], "clinical_studies": [ "14 CLINICAL STUDIES The efficacy of VEPPANU was evaluated in VERITAC-2 (NCT05654623), a randomized, open-label, active-controlled, multicenter trial that enrolled 624 adult patients with ER-positive, HER2-negative, advanced or metastatic breast cancer, of whom 270 patients had tumors carrying ESR1 mutations. Patients were required to have disease progression on 1 to 2 prior lines of endocrine therapy, including 1 line with a CDK4/6 inhibitor. Progression during or within 12 months from the end of adjuvant therapy was counted as 1 line of endocrine therapy for advanced/metastatic setting. Pre-menopausal and peri-menopausal women and men received a gonadotropin-releasing hormone (GnRH) agonist. Patients were excluded if they had received chemotherapy for advanced or metastatic disease or fulvestrant in any line of therapy, or if progression on the most recent line of endocrine therapy occurred within the first 6 months. Patients were randomized 1:1 to receive VEPPANU 200 mg orally once daily (N=313), or fulvestrant 500 mg intramuscularly on Days 1 and 15 of Cycle 1 and then once monthly thereafter (N=311). Randomization was stratified by ESR1 mutation status (detected vs. not detected) and visceral metastasis (yes vs. no). ESR1 mutational status was determined by blood circulating tumor deoxyribonucleic acid (ctDNA) using central or local testing. Patients were treated until disease progression or unacceptable toxicity. Among the patients whose tumors had ESR1 mutations (N=270), the median age was 60 (range: 26 to 87) years; all but 1 were female; 47% were White; 41% Asian; 3.3% Black; 8% unknown/not reported; 7% were Hispanic/ Latino, 83% were Not Hispanic or Latino and 10% not reported. Of the 269 women, 20% were pre/perimenopausal. Baseline Eastern Cooperative Oncology Group (ECOG) performance status was 0 (57%) or 1 (43%). Most patients (68%) had visceral disease; 81% had received 1 line of endocrine therapy and 19% had received 2 lines of endocrine therapy in the advanced or metastatic setting. All patients had received prior treatment with a CDK4/6 inhibitor. The major efficacy outcome was progression-free survival (PFS) as assessed by blinded independent central review (BICR) in the population of patients whose tumors had an ESR1 mutation and in the overall population evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. Additional efficacy outcomes were overall survival (OS) and objective response rate (ORR) as assessed by BICR. A statistically significant difference in PFS by BICR was observed for the patients whose tumors had ESR1 mutations for VEPPANU compared with fulvestrant. Overall survival was immature with 16% of deaths in this population at the time of the PFS analysis. Efficacy results are provided in Table 7 and Figure 1 .
