YUPELRI is a sterile, clear, colorless, aqueous solution of revefenacin. Revefenacin, the active component of YUPELRI, is an anticholinergic. The chemical name for revefenacin is 1-(2-{4-[(4-carbamoylpiperidin-1-yl)methyl]- N -methylbenzamido}ethyl)piperidin-4-yl N -({1,1’-biphenyl}-2-yl)carbamate; its structural formula is: Revefenacin has a molecular weight of 597.76 and its empirical formula is C 35 H 43 N 5 O 4 . Revefenacin is a white to off-white crystalline powder and is slightly soluble in water. YUPELRI is supplied as 3 mL of revefenacin solution packaged in a unit-dose low-density polyethylene vial overwrapped in a foil pouch. Each vial contains 175 mcg of revefenacin in 3 mL of an isotonic, sterile aqueous solution containing citric acid, sodium chloride, sodium citrate, and water for injection at pH 5.0. Hydrochloric acid or sodium hydroxide may be used to adjust the pH. YUPELRI does not require dilution prior to administration by nebulization. Like all other nebulized treatments, the amount delivered to the lungs will depend on patient factors, the nebulization system used, and compressor performance. Using the PARI LC ® Sprint nebulizer connected to a PARI Trek ® S compressor under in vitro conditions, the mean delivered dose from the mouthpiece was approximately 62 mcg (35% of label claim), at a mean flow rate of 4 LPM. The mean nebulization time was 8 minutes. YUPELRI should only be administered via a standard jet nebulizer connected to an air compressor with an adequate airflow, and equipped with a mouthpiece. Revefenacin Structural Formula

YUPELRI is indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). YUPELRI is an anticholinergic indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD) .

The recommended dosage is 175 mcg YUPELRI (one 175 mcg unit‑dose vial) administered by oral inhalation once daily by nebulizer using a mouthpiece. Administration Overview YUPELRI should be administered by the orally inhaled route via a standard jet nebulizer connected to an air compressor (See Instructions for Use) . The safety and efficacy of YUPELRI have been established in clinical trials when administered using the PARI LC ® Sprint nebulizer with a mouthpiece and the PARI Trek ® S compressor. The safety and efficacy of YUPELRI delivered from non‑compressor based nebulizer systems have not been established. The YUPELRI unit-dose vial should only be removed from the foil pouch and opened IMMEDIATELY BEFORE USE. The vial and any residual content should be discarded after use. No dosage adjustment is required for geriatric patients, or patients with renal impairment [see  Use in Specific Populations (8.5 , 8.7) and Clinical Pharmacology (12.3) ] . The drug compatibility (physical and chemical), efficacy, and safety of YUPELRI when mixed with other drugs in a nebulizer have not been established. For oral inhalation use only. Do not swallow YUPELRI. • One 175 mcg vial (3 mL) once daily. ( 2 ) • For use with a standard jet nebulizer with a mouthpiece connected to an air compressor. ( 2 )

Inhalation solution: 175 mcg of revefenacin in 3 mL of sterile, clear, colorless, aqueous solution in unit dose vials. Inhalation solution: 175 mcg of revefenacin per 3 mL solution in unit dose vials. ( 3 )

YUPELRI is contraindicated in patients with hypersensitivity to revefenacin or any component of this product. YUPELRI is contraindicated in patients with hypersensitivity to revefenacin or any component of this product. ( 4 )

• Do not initiate YUPELRI in acutely deteriorating COPD or to treat acute symptoms. ( 5.1 ) • If paradoxical bronchospasm occurs, discontinue YUPELRI and institute alternative therapy. ( 5.2 ) • Worsening of narrow-angle glaucoma may occur. Use with caution in patients with narrow-angle glaucoma and instruct patients to contact a healthcare provider immediately if symptoms occur. ( 5.3 ) • Worsening of urinary retention may occur. Use with caution in patients with prostatic hyperplasia or bladder-neck obstruction and instruct patients to contact a healthcare provider immediately if symptoms occur. ( 5.4 ) • Immediate hypersensitivity reactions may occur. If such a reaction occurs, therapy with YUPELRI should be stopped at once and alternative treatments should be considered. ( 5.5 ) YUPELRI should not be initiated in patients during acutely deteriorating or potentially life-threatening episodes of COPD. YUPELRI has not been studied in subjects with acutely deteriorating COPD. The initiation of YUPELRI in this setting is not appropriate. YUPELRI is intended as a once-daily maintenance treatment for COPD and should not be used for relief of acute symptoms, i.e. as rescue therapy for the treatment of acute episodes of bronchospasm, and extra doses should not be used for that purpose. Acute symptoms should be treated with an inhaled, short-acting beta 2 -agonist. COPD may deteriorate acutely over a period of hours or chronically over several days or longer. If YUPELRI no longer controls symptoms of bronchoconstriction, the patient's inhaled, short-acting beta 2 -agonist becomes less effective, or the patient needs more inhalations of a short-acting beta 2 -agonist than usual, these may be markers of deterioration of disease. In this setting, a re-evaluation of the patient and the COPD treatment regimen should be undertaken at once. Increasing the daily dose of YUPELRI beyond the recommended dose is not appropriate in this situation. As with other inhaled medicines, YUPELRI can produce paradoxical bronchospasm that may be life-threatening. If paradoxical bronchospasm occurs following dosing with YUPELRI, it should be treated immediately with an inhaled, short-acting bronchodilator; YUPELRI should be discontinued immediately and alternative therapy should be instituted. YUPELRI should be used with caution in patients with narrow-angle glaucoma. Prescribers and patients should be alert for signs and symptoms of acute narrow-angle glaucoma (e.g. eye pain or discomfort, blurred vision, visual halos or colored images in association with red eyes from conjunctival congestion and corneal edema). Instruct patients to consult a physician immediately if any of these signs or symptoms develops. YUPELRI should be used with caution in patients with urinary retention. Prescribers and patients should be alert for signs and symptoms of urinary retention (e.g. difficulty passing urine, painful urination), especially in patients with prostatic hyperplasia or bladder-neck obstruction. Instruct patients to consult a healthcare provider immediately if any of these signs or symptoms develops. Immediate hypersensitivity reactions may occur after administration of YUPELRI. If such a reaction occurs, therapy with YUPELRI should be stopped at once and alternative treatments should be considered.

The following clinically significant adverse reactions are described elsewhere in labeling:

• Anticholinergics: May interact additively with concomitantly used anticholinergic medications. Avoid administration of YUPELRI with other anticholinergic-containing drugs. ( 7.1 ) • Transporter-related drug interactions: Coadministration of YUPELRI with OATP1B1 and OATP1B3 inhibitors (e.g. rifampicin, cyclosporine, etc.) may lead to an increase in exposure of the active metabolite. Therefore, coadministration with YUPELRI is not recommended. ( 7.2 , 12.3 ) There is potential for an additive interaction with concomitantly used anticholinergic medicines. Therefore, avoid coadministration of YUPELRI with other anticholinergic-containing drugs as this may lead to an increase in anticholinergic adverse effects [see Warnings and Precautions (5.3 , 5.4 )] . OATP1B1 and OATP1B3 inhibitors (e.g. rifampicin, cyclosporine, etc.) could lead to an increase in systemic exposure of the active metabolite. Therefore, coadministration with YUPELRI is not recommended [see Clinical Pharmacology (12.3) ] .

Hepatic impairment: Avoid use of YUPELRI in patients with hepatic impairment. ( 8.6 , 12.3 ) There are no adequate and well-controlled studies with YUPELRI in pregnant women. Women should be advised to contact their physician if they become pregnant while taking YUPELRI. In animal reproduction studies, subcutaneous administration of revefenacin to pregnant rats and rabbits during the period of organogenesis produced no evidence of fetal harm at respective exposures approximately 209 times the exposure at the maximum recommended human dose (MRHD) (on an area under the curve [AUC] basis) (see  Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. In an embryo‑fetal development study in pregnant rats dosed during the period of organogenesis from gestation days 6 to 17, revefenacin was not teratogenic and did not affect fetal survival at exposures up to 209 times the MRHD (based upon summed AUCs for revefenacin and its active metabolite at maternal subcutaneous doses up to 500 mcg/kg/day). In an embryo‑fetal development study in pregnant rabbits dosed during the period of organogenesis from gestation days 7 to 19, revefenacin was not teratogenic and did not affect fetal survival at exposures up to 694 times the MRHD (based upon summed AUCs for revefenacin and its active metabolite at maternal subcutaneous doses up to 500 mcg/kg/day). Placental transfer of revefenacin and its active metabolite was observed in pregnant rabbits. In a pre- and postnatal development (PPND) study in pregnant rats dosed during the periods of organogenesis and lactation from gestation day 6 to lactation day 20, revefenacin had no adverse developmental effects on pups at exposures up to 196 times the MRHD (based upon summed AUCs for revefenacin and its active metabolite at maternal subcutaneous doses up to 500 mcg/kg/day). There is no information regarding the presence of revefenacin in human milk, the effects on the breastfed infant, or the effects on milk production. However, revefenacin was present in the milk of lactating rats following dosing during pregnancy and lactation (see Data ) . The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for YUPELRI and any potential adverse effects on the breastfed infant from YUPELRI or from the underlying maternal condition. In a PPND study [see Pregnancy (8.1) ], revefenacin and its active metabolite were present in milk of lactating rats on lactation day 22. Milk-to-plasma concentration ratios were up to 10 for revefenacin and its active metabolite. The safety and effectiveness of YUPELRI have not been established in pediatric patients. YUPELRI is not indicated for use in children. Based on available data, no adjustment of the dosage of YUPELRI in geriatric patients is necessary. Clinical trials of YUPELRI included 441 subjects aged 65 years and older, and of those, 101 subjects were aged 75 years and older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. The systemic exposure of revefenacin is unchanged while that of its active metabolite is increased in subjects with moderate hepatic impairment. The safety of YUPELRI has not been evaluated in COPD patients with mild-to-severe hepatic impairment. YUPELRI is not recommended in patients with any degree of hepatic impairment. [see Clinical Pharmacology (12.3) ] . No dosage adjustment is required in patients with renal impairment. Monitor for systemic antimuscarinic side effects in COPD patients with severe renal impairment. [see Clinical Pharmacology (12.3) ] .

Inhalation solution: YUPELRI is supplied as a 175 mcg/3 mL sterile, clear, colorless, aqueous solution in unit-dose low‑density polyethylene vials. Each vial is overwrapped in a foil pouch and supplied in cartons containing either 30 individually pouched unit‑dose vials (NDC 49502-806-93) or 7 individually pouched unit-dose vials (NDC 49502-806-77). Storage and Handling • Store YUPELRI in the protective foil pouch. • Store at room temperature from 68°F to 77°F (20°C to 25°C); excursions permitted from 59°F to 86°F (15°C to 30°C) [See USP Controlled Room Temperature]. Protect from direct sunlight and excessive heat. The YUPELRI solution unit-dose vial should only be removed from the foil pouch and opened IMMEDIATELY BEFORE USE. The vial and any residual content should be discarded after use. • Discard any solution that is not clear and colorless. • YUPELRI should only be administered via a standard jet nebulizer connected to an air compressor with an adequate airflow, and equipped with a mouthpiece. • Do not swallow or inject YUPELRI.

Revefenacin is a long-acting muscarinic antagonist, which is often referred to as an anticholinergic. It has similar affinity to the subtypes of muscarinic receptors M1 to M5. In the airways, it exhibits pharmacological effects through inhibition of M3 receptor at the smooth muscle leading to bronchodilation. The competitive and reversible nature of antagonism was shown with human and animal origin receptors and isolated organ preparations. In preclinical in vitro as well as in vivo models, prevention of methacholine- and acetylcholine-induced bronchoconstrictive effects was dose-dependent and lasted longer than 24 hours. The clinical relevance of these findings is unknown. The bronchodilation following inhalation of revefenacin is predominantly a site-specific effect. QTc interval prolongation was studied in a randomized, double-blind, placebo- and positive‑controlled, single dose, crossover trial in 48 healthy subjects. Following a single dose of revefenacin 700 mcg (4 times the recommended dosage), no effects on prolongation of QTc interval were observed. Revefenacin pharmacokinetic parameters are presented as the mean [standard deviation (SD)] unless otherwise specified. Following repeat dosing of inhaled YUPELRI, steady-state was achieved within 7 days with <1.6‑fold accumulation. Revefenacin exposure (C max and AUC) in COPD patients is approximately 60% lower as compared to healthy subjects. Exposure (C max and AUC) of the active metabolite in COPD patients is approximately 2-fold higher as compared to healthy subjects. Revefenacin C max was 0.16 ng/mL (0.11) and AUC was 0.22 ng·hr/mL (0.20) at steady-state after inhaled YUPELRI 175 mcg dose in COPD patients. C max of the active metabolite was 0.20 ng/mL (0.13) and AUC was 0.69 ng·hr/mL (0.53) at steady-state after inhaled YUPELRI 175 mcg dose in COPD patients. Revefenacin and its active metabolite exposure increased in a slightly greater than dose proportional manner with increasing revefenacin dose. After single or multiple once-daily dosing of YUPELRI, both AUC and C max of revefenacin and its active metabolite increased by approximately 11-fold over the 88 to 700 mcg (8‑fold) dose range. Following inhaled administration of YUPELRI in healthy subjects or COPD patients, C max of revefenacin and its active metabolite occurred at the first postdose sampling time which ranged from 14 to 41 minutes after start of nebulization. The absolute bioavailability following an oral dose of revefenacin is low (<3%). Following intravenous administration to healthy subjects, the mean steady-state volume of distribution of revefenacin was 218 L suggesting extensive distribution to tissues. In vitro protein binding of revefenacin and its active metabolite in human plasma was on average 71% and 42%, respectively. The terminal half-life of revefenacin and its active metabolite after once-daily dosing of YUPELRI in COPD patients is 22 to 70 hours. In vitro and in vivo data showed that revefenacin is primarily metabolized via hydrolysis of the primary amide to a carboxylic acid forming its major active metabolite. Following inhaled administration of YUPELRI in COPD patients, conversion to its active metabolite occurred rapidly, and plasma exposures of the active metabolite exceeded those of revefenacin by approximately 4- to 6-fold (based on AUC). The active metabolite is formed by hepatic metabolism and possesses activity at target muscarinic receptors that is lower (approximately one-third to one-tenth) than that of revefenacin. It could potentially contribute to systemic antimuscarinic effects at therapeutic doses. Following administration of a single intravenous dose of radiolabeled revefenacin to healthy male subjects, approximately 54% of total radioactivity was recovered in the feces and 27% was excreted in the urine. Approximately 19% of the administered radioactive dose was recovered in the feces as the active metabolite. Following administration of a single radiolabeled oral dose of revefenacin, 88% of total radioactivity was recovered in the feces and <5% was present in urine, suggesting low oral absorption. There was minimal renal excretion (<1%) of revefenacin and its active metabolite following inhaled administration of YUPELRI in COPD patients. Population pharmacokinetic analysis showed no evidence of a clinically significant effect of age (44 to 79 years), gender (59% male), smoking status (42% current smoker), or weight (46 to 155 kg) on systemic exposure of revefenacin and its active metabolite. The pharmacokinetics of YUPELRI was evaluated in subjects with moderate hepatic impairment (Child-Pugh score of 7-9). There was no increase in C max of revefenacin and 1.5-fold increase in C max of the active metabolite. There was 1.2-fold increase in AUC of revefenacin and up to 4.7-fold increase in AUC of the active metabolite. YUPELRI has not been evaluated in subjects with severe hepatic impairment. The pharmacokinetics of YUPELRI was evaluated in subjects with severe renal impairment (CrCl <30 mL/min). There was 1.5-fold increase in C max of revefenacin and up to 2-fold increase in C max of the active metabolite. There was up to 2.3‑fold increase in AUC inf of revefenacin; the active metabolite exposure (AUC inf ) was increased by up to 2.5-fold. YUPELRI has not been evaluated in subjects with end-stage renal disease. Neither revefenacin nor its active metabolite inhibits the following cytochrome P450 isoforms: CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4/5. Neither revefenacin nor its active metabolite induces CYP1A2, CYP2B6, and CYP3A4/5. Revefenacin is a substrate of P-gp and BCRP. Neither revefenacin nor its active metabolite is an inhibitor of these efflux transporters. The active metabolite of revefenacin is a substrate of OATP1B1 and OATP1B3. Neither revefenacin nor its active metabolite is an inhibitor of the uptake transporters OATP1B1, OATP1B3, OAT1, OAT3, or OCT2.

Two-year inhalation studies in Sprague-Dawley rats and CD1 mice were conducted to assess the carcinogenic potential of revefenacin. No evidence of tumorigenicity was observed in male and female rats at inhaled doses up to 338 mcg/kg/day (approximately 35 times the MRHD based upon summed AUCs for revefenacin and its active metabolite). No evidence of tumorigenicity was observed in male and female mice at inhaled doses up to 326 mcg/kg/day (approximately 40 times the MRHD based on summed AUCs for revefenacin and its active metabolite). Revefenacin and its active metabolite were negative for mutagenicity in the Ames test for bacterial gene mutation. Revefenacin was negative for genotoxicity in the in vitro mouse lymphoma assay and in vivo rat bone marrow micronucleus assay. There were no effects on male or female fertility and reproductive performance in rats at subcutaneous revefenacin doses up to 500 mcg/kg/day (approximately 30 times the MRHD on an mg/m 2 basis for revefenacin).

The safety and efficacy of YUPELRI 175 mcg once daily were evaluated in two dose‑ranging trials, two replicate 12-week, Phase 3 confirmatory clinical trials, and a 52-week safety trial. The efficacy of YUPELRI is primarily based on the two replicate 12-week, Phase 3 placebo-controlled trials in 1,229 subjects with COPD. Dose selection for YUPELRI was supported by a 28-day, randomized, double-blind, placebo-controlled, parallel-group trial of 355 subjects diagnosed with moderate to severe COPD, which was conducted to evaluate four doses of YUPELRI. YUPELRI 44, 88, 175, and 350 mcg, or matching placebo were taken once daily in the morning via a standard jet nebulizer (PARI LC ® Sprint Reusable Nebulizer) and evaluated using the primary efficacy endpoint of change from baseline in trough (predose) FEV 1 measured on Day 29. The LS mean differences in change from baseline in trough FEV 1 compared to placebo for the 44 mcg, 88 mcg, 175 mcg, and 350 mcg once-daily doses were 52 mL [95% CI: -17.3, 121.0], 187 mL [95% CI: 118.8, 256.1], 167 mL [95% CI: 97.3, 236.0], and 171 mL [95% CI: 101.9, 239.3], respectively. Evaluations of the dosing interval by comparing once- and twice-daily dosing of YUPELRI in a 7-day, randomized, double-blind, placebo-controlled, crossover trial in 64 patients supported selection of the once-daily dosing interval for further evaluation in the confirmatory COPD trials. The dose-ranging results supported the evaluation of two doses of YUPELRI, 88 mcg and 175 mcg once daily, in the confirmatory COPD trials. The clinical development program for YUPELRI included two 12-week, randomized, double-blind, placebo-controlled, multiple-dose, parallel-group, confirmatory trials in subjects with moderate to very severe COPD designed to evaluate the efficacy of once-daily YUPELRI’s effect on lung function (Trial 1: NCT02459080 and Trial 2: NCT02512510). To be enrolled, subjects needed to be 40 years of age or older, have a clinical diagnosis of COPD, a history of smoking greater than or equal to 10 pack-years, moderate to very severe COPD (post‑ipratropium FEV 1 less than or equal to 80% of predicted normal values but at least 700 mL), and an FEV 1 /FVC ratio of 0.7 or less. Trials 1 and 2 included 1,229 subjects of which 395 received the 175 mcg dose administered via a standard jet nebulizer (PARI LC ® Sprint Reusable Nebulizer). The study population had a mean age of 64 years (range: 41 to 88) and mean smoking history of 53 pack-years, with 48% identified as current smokers. At screening, the mean post-bronchodilator percent predicted FEV 1 was 55% (range: 10% to 90%), and the post-bronchodilator FEV 1 /FVC ratio was 0.54 (range: 0.3 to 0.7). In addition, of the subjects enrolled, 37% were taking LABA or ICS/LABA therapy at study entry and remained on this concomitant therapy throughout the study. Trials 1 and 2 evaluated YUPELRI 175 mcg once daily and placebo once daily. The primary endpoint was change from baseline in trough (predose) FEV 1 at Day 85. In both trials, YUPELRI 175 mcg demonstrated significant improvement in lung function (mean change from baseline in trough (predose) FEV 1 ) compared to placebo. Table 2 presents the results from Trial 1 and Trial 2. The change from baseline in trough FEV 1 over time from Trial 1 is depicted in Figure 1.
