Overactive Bladder in Adults The safety of GEMTESA was evaluated in a 12-week, double-blind, placebo- and active-controlled study (Study 3003) in patients with OAB [see Clinical Studies ( 14.1 )] . A total of 545 patients received GEMTESA. The majority of the patients were White (78%) and female (85%) with a mean age of 60 years (range 18 to 93 years). Adverse reactions that were reported in Study 3003 at an incidence greater than placebo and in ≥2% of patients treated with GEMTESA are listed in Table 1 . Table 1: Adverse Reactions, Exceeding Placebo Rate, Reported in ≥2% of Patients Treated with GEMTESA 75 mg for up to 12 Weeks in Study 3003 GEMTESA 75 mg n (%) Placebo n (%) Number of Patients 545 540 Headache 22 (4.0) 13 (2.4) Nasopharyngitis 15 (2.8) 9 (1.7) Diarrhea 12 (2.2) 6 (1.1) Nausea 12 (2.2) 6 (1.1) Upper respiratory tract infection 11 (2.0) 4 (0.7) Other adverse reactions reported in <2% of patients treated with GEMTESA included: Gastrointestinal disorders: dry mouth, constipation Investigations: residual urine volume increased Renal and urinary disorders: urinary retention Vascular disorders: hot flush GEMTESA was also evaluated for long-term safety in an extension study (Study 3004) in 505 patients who completed the 12-week study (Study 3003). Of the 273 patients who received GEMTESA 75 mg once daily in the extension study, 181 patients were treated for a total of one year. Adverse reactions reported in ≥2% of patients treated with GEMTESA 75 mg for up to 52 weeks in the long-term extension study, and not already listed above, were urinary tract infection (6.6%) and bronchitis (2.9%). Overactive Bladder in Adult Males with BPH The safety of GEMTESA was evaluated in a 24-week double-blind, randomized, placebo-controlled study (Study 3005) in male patients with OAB on pharmacological therapy for BPH. A total of 553 patients received GEMTESA [see Clinical Studies ( 14.2 )] . Adverse reactions that were reported in Study 3005 at an incidence greater than placebo and in ≥2% of patients treated with GEMTESA are listed in Table 2 .

Number of Patients 553 551 Hypertension* 50 (9.0) 46 (8.3) Urinary tract infection 14 (2.5) 12 (2.2) GEMTESA was also evaluated for long-term safety in a 28-week extension study (Study 3006) in 276 patients who completed the 24-week study (Study 3005). Of the 276 patients who received GEMTESA 75 mg once daily in the extension study, 124 patients were treated for a total of one year. There were no additional adverse reactions reported in Study 3006 that are not already included in Section 6.1 above. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of vibegron. 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. The following adverse events have been reported in association with vibegron use in worldwide postmarketing experience: Urologic disorders : urinary retention Skin and subcutaneous tissue disorders : angioedema of the face and larynx; hypersensitivity reactions, including urticaria, pruritus, rash and drug eruption; eczema Gastrointestinal disorders : constipation

Drug interactions

Concomitant use of GEMTESA increases digoxin maximal concentrations (C max ) and systemic exposure as assessed by area under the concentration-time curve (AUC) [see Clinical Pharmacology ( 12.3 )] . Serum digoxin concentrations should be monitored before initiating and during therapy with GEMTESA and used for titration of the digoxin dose to obtain the desired clinical effect. Continue monitoring digoxin concentrations upon discontinuation of GEMTESA and adjust digoxin dose as needed. Digoxin : Measure serum digoxin concentrations before initiating GEMTESA. Monitor serum digoxin concentrations to titrate digoxin dose to desired clinical effect. ( 7 )

Use in specific populations

Pediatric use : Safety and effectiveness in pediatric patients have not been established. ( 8.4 ) End-stage Renal Disease with or without Hemodialysis : Not recommended. ( 8.6 ) Severe Hepatic Impairment : Not recommended. ( 8.7 ) 8.1 Pregnancy Risk Summary There are no available data on GEMTESA use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal studies, no effects on embryo-fetal development were observed following administration of vibegron during the period of organogenesis at exposures approximately 275-fold and 285-fold greater than clinical exposure at the recommended daily dose of GEMTESA, in rats and rabbits, respectively. Delayed fetal skeletal ossification was observed in rabbits at approximately 898-fold clinical exposure, in the presence of maternal toxicity. In rats treated with vibegron during pregnancy and lactation, no effects on offspring were observed at 89-fold clinical exposure. Developmental toxicity was observed in offspring at approximately 458-fold clinical exposure, in the presence of maternal toxicity. No effects on offspring were observed at 89-fold clinical exposure (see Data ). The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies carry some 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 2-4% and 15-20%, respectively. Data Animal Data In an embryo-fetal developmental toxicity study, pregnant rats were treated with daily oral doses of 0, 30, 100, 300, or 1000 mg/kg/day vibegron during the period of organogenesis (Days 6 to 20 of gestation). These doses were associated with systemic exposures (AUC) 0-, 9-, 89-, 275-, and 1867-fold higher, respectively, than in humans treated with the recommended daily dose of GEMTESA. No embryo-fetal developmental toxicity was observed at doses up to 300 mg/kg/day. Treatment with the high dose of 1000 mg/kg/day was discontinued due to maternal toxicity. In an embryo-fetal developmental toxicity study, pregnant rabbits were treated with daily oral doses of 0, 30, 100, or 300 mg/kg/day vibegron during the period of organogenesis (Days 7 to 20 of gestation). These doses were associated with systemic exposures (AUC) 0-, 86-, 285-, and 898-fold higher, respectively, than in humans treated with the recommended daily dose of GEMTESA. No embryo-fetal developmental toxicity was observed at doses of vibegron up to 100 mg/kg/day. Maternal toxicity (decreased food consumption), reduced fetal body weight, and an increased incidence of delayed skeletal ossification, were observed at 300 mg/kg/day. In a pre- and post-natal developmental toxicity study, pregnant or lactating rats were treated with daily oral doses of 0, 30, 100, or 500 mg/kg/day vibegron from day 6 of gestation through day 20 of lactation. These doses were associated with estimated systemic exposures (AUC) 0-, 9-, 89-, and 458-fold higher, respectively, than in humans treated with the recommended daily dose of GEMTESA. No developmental toxicity was observed in F1 offspring at doses up to 100 mg/kg/day. Maternal toxicity was observed during lactation (decreased body weight gain) at doses ≥100 mg/kg/day and during gestation (decreased body weight gain and food consumption) at 500 mg/kg/day. Developmental toxicity was observed in F1 offspring (increased stillborn index, lethality, reduced viability and weaning indices, decreased body weight and body weight gains, low physical development differentiation indices, and effects on sensory function and reflexes) at 500 mg/kg/day. 8.2 Lactation Risk Summary There are no data on the presence of vibegron in human milk, the effects of the drug on the breastfed infant, or the effects on milk production. When a single oral dose of radiolabeled vibegron was administered to postnatal nursing rats, radioactivity was observed in milk (see Data ). 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 GEMTESA and any potential adverse effects on the breastfed infant from GEMTESA or from the underlying maternal condition. Data Animal Data In a lactational transfer study, lactating rats were treated with a single oral dose of 10 mg/kg radiolabeled [ 3 H] vibegron on postpartum day 10. Levels of radioactivity were determined in milk and plasma collected at 1, 4, 12, and 24 after dosing. The C max of total radioactivity in milk and plasma were observed at 9 and 2 hours after dosing, respectively, with a maximum milk-to-plasma concentration ratio of 2.2 observed at 12 hours after dosing. Vibegron elimination from milk showed a similar trend as that from plasma. The radioactivity concentration in milk at 24 hours after administration was approximately 25% of the C max . 8.4 Pediatric Use The safety and effectiveness of GEMTESA in pediatric patients have not been established. 8.5 Geriatric Use Of 526 patients who received GEMTESA in the clinical studies for OAB with symptoms of urge urinary incontinence, urgency, and urinary frequency, 242 (46%) were 65 years of age or older, and 75 (14%) were 75 years of age or older [see Clinical Studies ( 14.1 )] . No overall differences in safety or effectiveness of GEMTESA have been observed between patients 65 years of age and older and younger adult patients. Of the total number of GEMTESA-treated patients in clinical studies for OAB with symptoms of urge urinary incontinence, urgency, and urinary frequency in adult males on pharmacological therapy for benign prostatic hyperplasia (BPH), 347 (63%) were 65 years of age and older, while 100 (18%) were 75 years of age and older [see Clinical Studies ( 14.2 )] .
