In animal embryo fetal development (EFD) studies, oral administration of brensocatib to pregnant rats during organogenesis at maternal exposures 128 times the maximum recommended human dose (MRHD) on an AUC basis was associated with malformations. Oral administration of brensocatib to pregnant rabbits during organogenesis demonstrated no adverse developmental effects at doses that produced maternal exposures up to 20 times the MRHD. No adverse development effects were observed after oral administration of brensocatib to pregnant rats from the period of organogenesis through lactation at doses that produced maternal exposures 17 times the MRHD on an AUC basis (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population 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. Data Animal Data In a rat fertility and EFD study, brensocatib was administered at oral doses of 3, 20, and 100 mg/kg/day to female rats 2 weeks prior to mating, during mating, and through organogenesis until gestation Day 16. The malformation of bent scapula was observed at a maternal dose of 100 mg/kg/day (128 times the MRHD on an AUC basis). There were no adverse findings at maternal oral doses of 20 mg/kg/day (42 times the MRHD on an AUC basis). In a rabbit EFD study, brensocatib was administered at oral doses of 5, 15, or 50 mg/kg/day from gestation Days 7 to 19, a period that covers implantation and major organogenesis. Brensocatib was not associated with adverse effects on the fetus at maternal exposures up to 20 times the MRHD on an AUC basis. Maternal toxicity as indicated by reductions in body weight gain and food consumption was noted at maternal doses of 15 mg/kg/day and greater (greater than 5 times the MRHD on an AUC basis). In a pre- and postnatal development study, oral administration of brensocatib to pregnant rats at doses of 3, 9, or 20 mg/kg/day from gestation Day 6 through lactation Day 20 resulted in no adverse developmental effects in pups at maternal doses up to 20 mg/kg/day (17 times the MRHD on an AUC basis)."],"overdosage":["10 OVERDOSAGE Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for overdose management recommendations."],"description":["11 DESCRIPTION BRINSUPRI (brensocatib) is a dipeptidyl peptidase 1 (DPP1) inhibitor.

ASPEN was a 52-week trial that included 1721 adult and pediatric patients 12 years of age and older with NCFB (1680 adults and 41 pediatric patients 12 years of age to less than 18 years of age) who were randomized to BRINSUPRI 10 mg (n=583), BRINSUPRI 25 mg (n=575), or placebo (n=563) administered orally once daily. WILLOW was a 24-week trial that included 256 adult patients with NCFB who were randomized to BRINSUPRI 10 mg (n=82), BRINSUPRI 25 mg (n=87), or placebo (n=87) administered orally once daily. In both ASPEN and WILLOW, all adult patients had a history of confirmed NCFB by chest computed tomography with at least 2 documented pulmonary exacerbations (PEx) prior to screening in the past 12 months. In ASPEN, pediatric patients 12 years of age and older had at least one PEx in the prior 12 months. Demographics and baseline characteristics of patients in ASPEN and WILLOW are provided in Table 2 .

Following once daily administration of brensocatib 25 mg, the estimated geometric mean (CV%) C max is 259 ng/mL (31%) and AUC tau is 4060 ng*h/mL (39%). Brensocatib C max and AUC tau increase in a greater than dose proportional manner between doses of 10 mg and 1.6 times the highest recommended dose. Between doses of 10 mg and 1.6 times the highest recommended dose brensocatib once daily, brensocatib geometric mean steady state C max increased by 5.1-fold and AUC tau increased by 5.3-fold. In healthy subjects, at steady state, C max increased by about 1.5-fold and AUC tau increased by about 2-fold when compared to those observed following a single dose. No clinically relevant differences in brensocatib pharmacokinetics were observed between healthy subjects and patients with NCFB. Absorption The absolute oral bioavailability of brensocatib has not been studied in humans. Based on data from a mass balance study in healthy subjects, the oral absorption of brensocatib in humans is greater than 80%. Following a single dose of 10 mg or 25 mg brensocatib, the median (min, max) time to maximum plasma concentration (T max ) is 1.0-1.4 hours (0.5, 3.0 hours). Effect of Food No clinically relevant differences in brensocatib pharmacokinetics were observed following administration of brensocatib with a high-fat meal (990 calories, 52% fat). Distribution Following once daily administration of 10 mg or 25 mg brensocatib in patients with NCFB, the estimated volume of distribution at steady state ranged from 126 to 138 L. The protein binding of brensocatib in human plasma was 87.2%. Elimination Following a single oral administration of brensocatib at 10 mg or 25 mg in healthy subjects, the elimination half-life ranged from 25 to 39 hours and the apparent oral clearance ranged from 6.4 to 10.7 L/hour. Metabolism Brensocatib is primarily metabolized by CYP3A and to a lesser extent by CYP2C8 and CYP2D6. Brensocatib accounted for 16.2% of the total radioactivity in plasma. One major circulating metabolite, thiocyanate, was identified in plasma and accounted for 51% of the total radioactivity AUC following administration of a radio-labeled brensocatib dose. In patients with NCFB at recommended doses of brensocatib, no clinically meaningful changes of plasma thiocyanate from baseline were observed. Excretion Following administration of a single oral dose of radiolabeled brensocatib 1.6 times the highest recommended dose to healthy subjects, 54.2% of dose was recovered in urine (22.8% as unchanged brensocatib) and 28.3% of dose was recovered in feces (2.4% as unchanged brensocatib). Specific Populations No clinically significant differences in the pharmacokinetics of brensocatib were observed based on age (12 to 85 years), sex, race (72% White, 6% Black, and 12% Asian), or body weight (32 to 155 kg). No clinically significant differences in the pharmacokinetics of brensocatib were observed based on mild, moderate, or severe renal impairment (eGFR 15-89 mL/min/1.73 m 2 ); or mild, moderate, or severe hepatic impairment (Child-Pugh Class A, B, or C). Drug Interaction Studies Clinical Studies and Model-Informed Approaches Strong CYP3A4 and P-gp Inhibitors : Brensocatib C max increased by 68% and AUC increased by 55% following concomitant administration with clarithromycin (a strong CYP3A4 and P-gp inhibitor) 500 mg twice daily for 6 days. Moderate CYP3A4 and P-gp Inhibitors : Brensocatib C max increased by 53% and AUC increased by 32% following concomitant administration with verapamil (a moderate CYP3A4 and P-gp inhibitor) 240 mg once daily for 5 days. Strong CYP3A4 Inducers : Brensocatib C max decreased by 15% and AUC decreased by 33% following concomitant administration with rifampin (a strong CYP3A4 inducer) 600 mg once daily for 9 days. Acid-Reducing Agents : Brensocatib C max and AUC were unchanged following concomitant administration with esomeprazole (a proton-pump inhibitor) 40 mg once daily for 4 days. CYP3A4 Substrates : No clinically significant differences in the pharmacokinetics of midazolam (a sensitive CYP3A4 substrate) are predicted when used concomitantly with brensocatib. In Vitro Studies CYP450 Enzymes : Brensocatib is a substrate of CYP3A. Brensocatib does not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, or CYP3A. Brensocatib is a weak CYP3A inducer, but not an inducer of CYP1A2, CYP2B6, CYP2C8, CYP2C9, or CYP2C19.

Specific Populations No clinically significant differences in the pharmacokinetics of brensocatib were observed based on age (12 to 85 years), sex, race (72% White, 6% Black, and 12% Asian), or body weight (32 to 155 kg). No clinically significant differences in the pharmacokinetics of brensocatib were observed based on mild, moderate, or severe renal impairment (eGFR 15-89 mL/min/1.73 m 2 ); or mild, moderate, or severe hepatic impairment (Child-Pugh Class A, B, or C). Drug Interaction Studies Clinical Studies and Model-Informed Approaches Strong CYP3A4 and P-gp Inhibitors : Brensocatib C max increased by 68% and AUC increased by 55% following concomitant administration with clarithromycin (a strong CYP3A4 and P-gp inhibitor) 500 mg twice daily for 6 days. Moderate CYP3A4 and P-gp Inhibitors : Brensocatib C max increased by 53% and AUC increased by 32% following concomitant administration with verapamil (a moderate CYP3A4 and P-gp inhibitor) 240 mg once daily for 5 days. Strong CYP3A4 Inducers : Brensocatib C max decreased by 15% and AUC decreased by 33% following concomitant administration with rifampin (a strong CYP3A4 inducer) 600 mg once daily for 9 days. Acid-Reducing Agents : Brensocatib C max and AUC were unchanged following concomitant administration with esomeprazole (a proton-pump inhibitor) 40 mg once daily for 4 days. CYP3A4 Substrates : No clinically significant differences in the pharmacokinetics of midazolam (a sensitive CYP3A4 substrate) are predicted when used concomitantly with brensocatib. In Vitro Studies CYP450 Enzymes : Brensocatib is a substrate of CYP3A. Brensocatib does not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, or CYP3A. Brensocatib is a weak CYP3A inducer, but not an inducer of CYP1A2, CYP2B6, CYP2C8, CYP2C9, or CYP2C19. Transporter Systems : Brensocatib is a substrate of P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP), but is not a substrate of MATE1, MATE2-K, OAT1, OAT3, OATP1B1, OATP1B3, OCT1, and OCT2. Brensocatib is an inhibitor of BCRP, OATP1B, MATE1, and MATE2-K, but is not an inhibitor of P-gp, OAT1, OCT2, OAT3, or OATP1B3."],"indications_and_usage":["1 INDICATIONS AND USAGE BRINSUPRI is indicated for the treatment of non-cystic fibrosis bronchiectasis (NCFB) in adult and pediatric patients 12 years of age and older.

In animal embryo fetal development (EFD) studies, oral administration of brensocatib to pregnant rats during organogenesis at maternal exposures 128 times the maximum recommended human dose (MRHD) on an AUC basis was associated with malformations. Oral administration of brensocatib to pregnant rabbits during organogenesis demonstrated no adverse developmental effects at doses that produced maternal exposures up to 20 times the MRHD. No adverse development effects were observed after oral administration of brensocatib to pregnant rats from the period of organogenesis through lactation at doses that produced maternal exposures 17 times the MRHD on an AUC basis (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population 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. Data Animal Data In a rat fertility and EFD study, brensocatib was administered at oral doses of 3, 20, and 100 mg/kg/day to female rats 2 weeks prior to mating, during mating, and through organogenesis until gestation Day 16. The malformation of bent scapula was observed at a maternal dose of 100 mg/kg/day (128 times the MRHD on an AUC basis). There were no adverse findings at maternal oral doses of 20 mg/kg/day (42 times the MRHD on an AUC basis). In a rabbit EFD study, brensocatib was administered at oral doses of 5, 15, or 50 mg/kg/day from gestation Days 7 to 19, a period that covers implantation and major organogenesis. Brensocatib was not associated with adverse effects on the fetus at maternal exposures up to 20 times the MRHD on an AUC basis. Maternal toxicity as indicated by reductions in body weight gain and food consumption was noted at maternal doses of 15 mg/kg/day and greater (greater than 5 times the MRHD on an AUC basis). In a pre- and postnatal development study, oral administration of brensocatib to pregnant rats at doses of 3, 9, or 20 mg/kg/day from gestation Day 6 through lactation Day 20 resulted in no adverse developmental effects in pups at maternal doses up to 20 mg/kg/day (17 times the MRHD on an AUC basis). 8.2 Lactation Risk Summary There are no data on the presence of brensocatib and/or its metabolite(s) in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for BRINSUPRI and any potential adverse effects on the breastfed child from BRINSUPRI or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of BRINSUPRI for the treatment of NCFB have been established in pediatric patients aged 12 years and older. Use of BRINSUPRI for this indication is supported by evidence from an adequate and well-controlled trial (ASPEN), which enrolled 41 pediatric patients aged 12 years and older, and additional pharmacokinetic data in pediatric patients aged 12 to 17 years [see Clinical Pharmacology (12.3) and Clinical Studies (14) ]. Common adverse reactions in pediatric patients aged 12 years and older enrolled in ASPEN were consistent with those in adults [see Adverse Reactions (6.1) ] . The safety and effectiveness of BRINSUPRI have not been established in pediatric patients younger than 12 years of age. 8.5 Geriatric Use There were 988 patients 65 years of age and older in the clinical studies for non-cystic fibrosis bronchiectasis [see Clinical Studies (14) ] . Of the total number of BRINSUPRI-treated patients in these studies, 676 (51%) were 65 years of age and older while 201 (15%) were 75 years of age and older. No observed differences in safety and/or effectiveness in geriatric patients compared to younger adult patients [see Clinical Pharmacology (12.3) ] ."],"spl_patient_package_insert_table":["<table width=\"100%\"><col width=\"2%\" align=\"left\" valign=\"top\"/><col width=\"53%\" align=\"left\" valign=\"top\"/><col width=\"45%\" align=\"left\" valign=\"top\"/><thead><tr><th styleCode=\"Lrule Rrule\" colspan=\"3\" align=\"center\">Patient Information BRINSUPRI (brin-SOO-pree)  (brensocatib) tablets, for oral use</th></tr></thead><tfoot><tr><td align=\"left\" colspan=\"2\">This Patient Information has been approved by the U.S. Food and Drug Administration</td><td align=\"right\">Issued: 03/2026</td></tr></tfoot><tbody><tr styleCode=\"Botrule\"><td styleCode=\"Lrule Rrule\" align=\"left\" colspan=\"3\"><content styleCode=\"bold\">What is BRINSUPRI?</content> BRINSUPRI is a prescription medicine used to treat non-cystic fibrosis bronchiectasis (NCFB) in adults and children 12 years of age and older.
