Hypersensitivity reactions have included anaphylaxis [see Warnings and Precautions (5.1) ] . taking pimozide. Inhibition of CYP3A4 by aprepitant could result in elevated plasma concentrations of pimozide, which is a CYP3A4 substrate, potentially causing serious or life-threatening reactions, such as QT prolongation, a known adverse reaction of pimozide [see Drug Interactions (7.1) ] . Known hypersensitivity to any component of this product. ( 4 , 5.1 ) Concurrent use with pimozide. ( 4 )

Warnings and precautions

Hypersensitivity Reactions (including anaphylaxis) : May occur during or soon after administration. If symptoms occur, administer appropriate medical therapy. ( 4 , 5.1 ) CYP3A4 Interactions : Aprepitant is a substrate, weak-to-moderate inhibitor, and inducer of CYP3A4; see full prescribing information. ( 5.2 , 7.2 ) Warfarin (a CYP2C9 substrate) : Risk of decreased INR of prothrombin time; monitor INR in 2-week period, particularly at 7 to 10 days, following administration of APONVIE. ( 5.3 , 7.1 ) Hormonal Contraceptives : Efficacy of contraceptives may be reduced for 28 days following administration of aprepitant. Use effective alternative or back-up methods of non-hormonal contraception. ( 5.4 , 7.1 , 8.3 ) 5.1 Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis, during or soon after administration of aprepitant have occurred. Symptoms including dyspnea, eye swelling, flushing, pruritus, and wheezing have been reported [see Adverse Reactions (6.2) ] . Monitor patients during and after administration. If hypersensitivity reactions occur, administer appropriate medical therapy. Do not administer APONVIE in patients who experience these symptoms with previous use of aprepitant. 5.2 Clinically Significant CYP3A4 Drug Interactions Aprepitant is a substrate, a weak-to-moderate (dose-dependent) inhibitor, and an inducer of CYP3A4. Use of pimozide, a CYP3A4 substrate, with APONVIE is contraindicated [see Contraindications (4) ] . Use of APONVIE with strong CYP3A4 inhibitors (e.g., ketoconazole) may increase plasma concentrations of aprepitant and result in an increased risk of adverse reactions related to APONVIE [see Drug Interactions (7.2) ] . Use of APONVIE with strong CYP3A4 inducers (e.g., rifampin) may result in a reduction in aprepitant plasma concentrations and decreased efficacy of APONVIE [see Drug Interactions (7.2) ]. 5.3 Decrease in INR with Concomitant Warfarin Use of aprepitant with warfarin, a CYP2C9 substrate, may result in a clinically significant decrease in the International Normalized Ratio (INR) of prothrombin time [see Clinical Pharmacology (12.3) ] . Monitor the INR in patients on chronic warfarin therapy in the 2-week period, particularly at 7 to 10 days, following administration of APONVIE [see Drug Interactions (7.1) ] . 5.4 Risk of Reduced Efficacy of Hormonal Contraceptives The efficacy of hormonal contraceptives may be reduced for 28 days following administration of APONVIE [see Clinical Pharmacology (12.3) ] . Advise patients to use effective alternative or back-up methods of non-hormonal contraception for 1 month following administration of APONVIE [see Drug Interactions (7.1) and Use in Specific Populations (8.3) ] .

Side effects

The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] Most common adverse reactions (incidence ≥3%) are ( 6.1 ): Single-dose APONVIE: constipation, fatigue, and headache. Single-dose oral aprepitant: constipation and hypotension. To report SUSPECTED ADVERSE REACTIONS, contact Heron Therapeutics, Inc. at 1-844-437-6611 and www.APONVIE.com or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The safety of APONVIE for prevention of PONV was evaluated as a single dose in healthy subjects and established from adequate and well-controlled studies of oral aprepitant [see Clinical Studies (14) ] . Adverse reactions observed in these studies are described below. Safety of APONVIE A total of 51 healthy subjects received a single 32 mg dose of APONVIE as a 30 second intravenous injection. Adverse reactions reported in at least 3% of subjects were constipation (8%), fatigue (6%), and headache (4%). Safety of Oral Aprepitant In 2 active-controlled, double-blind clinical studies in patients receiving general anesthesia (Studies 1 and 2), 40 mg oral aprepitant was compared to 4 mg intravenous ondansetron [see Clinical Studies (14) ] . There were 564 patients treated with oral aprepitant and 538 patients treated with ondansetron. The most common adverse reactions reported in patients treated with oral aprepitant for PONV in pooled Studies 1 and 2 are listed in Table 1. Table 1: Most Common Adverse Reactions in Oral Aprepitant-Treated Patients in a Pooled Analysis of PONV Studies Reported in ≥3% of patients treated with oral aprepitant 40 mg and at a greater incidence than with ondansetron. Oral Aprepitant 40 mg (N = 564) Ondansetron (N = 538) Constipation 9% 8% hypotension 6% 5% In a pooled analysis of PONV studies, less common adverse reactions reported in more than 0.5% of patients treated with oral aprepitant and at a greater incidence than ondansetron were dizziness and urticaria. In addition, two serious adverse reactions were reported in PONV clinical studies of oral aprepitant in patients taking a higher than recommended dose: one case of constipation, and one case of sub-ileus. Other Studies Angioedema, urticaria, and Stevens-Johnson syndrome were reported as serious adverse reactions in patients receiving oral aprepitant in non-PONV studies. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of aprepitant. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Skin and subcutaneous tissue disorders : pruritus, rash, urticaria, Stevens-Johnson syndrome/toxic epidermal necrolysis [see Warnings and Precautions (5.1) ] . Immune system disorders : hypersensitivity reactions including anaphylaxis and anaphylactic shock [see Contraindications (4) and Warnings and Precautions (5.1) ] . Nervous system disorders : ifosfamide-induced neurotoxicity reported after aprepitant and ifosfamide coadministration.

Use in specific populations

Pregnancy : May cause fetal harm. ( 8.1 ) 8.1 Pregnancy Risk Summary There are insufficient data on aprepitant use in pregnant women to identify a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Avoid use of APONVIE in pregnant women due to the alcohol content (see Clinical Considerations ) . In animal reproduction studies, no adverse developmental effects were observed in rats or rabbits exposed during the period of organogenesis to systemic drug concentrations (area under the plasma-concentration time curve [AUC]) of oral aprepitant approximately 4.8 times the exposure at the recommended human dose of APONVIE (see Data ) . The background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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. Clinical Considerations Fetal/Neonatal Adverse Reactions APONVIE contains alcohol. Published studies have demonstrated that alcohol is associated with fetal harm including central nervous system abnormalities, behavioral disorders, and impaired intellectual development. There is no safe level of alcohol exposure in pregnancy; therefore, avoid use of APONVIE in pregnant women. Data Animal Data In embryofetal development studies in rats and rabbits, aprepitant was administered during the period of organogenesis at oral doses up to 1000 mg/kg twice daily (rats) and up to the maximum tolerated dose of 125 mg/kg/day (rabbits). No embryofetal lethality or malformations were observed at any dose level in either species. The exposures (AUC) in pregnant rats at 1000 mg/kg twice daily and in pregnant rabbits at 125 mg/kg/day were approximately 4.8 times the exposure at the recommended human dose of APONVIE. Aprepitant crosses the placenta in rats and rabbits. 8.2 Lactation Risk Summary There are no data on the presence of aprepitant in human milk, the effects on the breastfed infant, or the effects on milk production. Aprepitant is present in rat milk. When a drug is present in animal milk, it is likely that the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for APONVIE and any potential adverse effects on the breastfed infant from APONVIE or from the underlying maternal condition. 8.3 Females and Males of Reproductive Potential Contraception Upon administration of APONVIE, the efficacy of hormonal contraceptives may be reduced. Advise females of reproductive potential using hormonal contraceptives to use an effective alternative or back-up non-hormonal contraceptive (such as condoms or spermicides) for 1 month following administration of APONVIE [see Warnings and Precautions (5.4) , Drug Interactions (7.1) , and Clinical Pharmacology (12.3) ] . 8.4 Pediatric Use The safety and effectiveness of APONVIE have not been established in pediatric patients. Juvenile Animal Study A study was conducted in young rats to evaluate the effects of aprepitant on growth and on neurobehavioral and sexual development. Rats were treated at oral doses up to the maximum feasible dose of 1000 mg/kg twice daily from the early postnatal period (Postnatal Day 10) through Postnatal Day 58. Slight changes in the onset of sexual maturation were observed in female and male rats; however, there were no effects on mating, fertility, embryonic-fetal survival, or histomorphology of the reproductive organs. There were no effects in neurobehavioral tests of sensory function, motor function, and learning and memory. 8.5 Geriatric Use Of the 1120 adult patients treated with oral aprepitant in PONV clinical studies, 7% were aged 65 and over, while 2% were aged 75 and over. Clinical studies of aprepitant did not include sufficient numbers of subjects aged 65 and over to determine whether they responded differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. No clinically meaningful differences in the pharmacokinetics of oral aprepitant were observed in healthy geriatric subjects compared to younger adult subjects [see Clinical Pharmacology (12.3) ] .

Overdosage

Headache, fatigue, and dizziness were reported in healthy subjects receiving a single dose of 100 or 130 mg aprepitant injectable emulsion (3.1 to 4 times the recommended dose). Drowsiness and headache were reported in one patient who ingested 1440 mg of oral aprepitant. In the event of overdose, general supportive treatment and monitoring should be provided. Aprepitant is not removed by hemodialysis.

Description

11 DESCRIPTION APONVIE injectable emulsion contains the active ingredient, aprepitant. Aprepitant is a substance P/neurokinin 1 (NK 1 ) receptor antagonist, an antiemetic agent, and chemically described as 5-[[(2 R ,3 S )-2-[(1 R )-1-[3,5-bis(trifluoromethyl)phenyl]ethoxy]-3-(4-fluorophenyl)-4-morpholinyl]methyl]-1,2-dihydro-3 H -1,2,4-triazol-3-one. Its empirical formula is C 23 H 21 F 7 N 4 O 3 , and its structural formula is: Aprepitant is a white to off-white crystalline solid, with a molecular weight of 534.43. It is practically insoluble in water. Aprepitant is sparingly soluble in ethanol and isopropyl acetate and slightly soluble in acetonitrile. APONVIE (aprepitant) injectable emulsion is a sterile, opaque, off-white to amber liquid in a single-dose vial for intravenous use. Each vial contains 32 mg aprepitant in 4.4 mL of emulsion. The emulsion also contains the following inactive ingredients: dehydrated alcohol (125 mg), egg lecithin (636 mg), sodium oleate (21 mg), soybean oil (424 mg), sucrose (238 mg), and water for injection (2968 mg). Chemical Structure

Mechanism of action

12.1 Mechanism of Action Aprepitant is a selective high-affinity antagonist of human substance P/neurokinin 1 (NK 1 ) receptors. Aprepitant has little or no affinity for serotonin (5-HT 3 ), dopamine, and corticosteroid receptors, the targets of existing therapies for postoperative nausea and vomiting (PONV). Aprepitant has been shown in animal models to inhibit emesis via central actions. Animal and human Positron Emission Tomography (PET) studies with aprepitant have shown that it crosses the blood brain barrier and occupies brain NK 1 receptors.
