6.1 Clinical Trials Experience

CLINICAL TRIALS EXPERIENCE SECTION

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 practice.

The safety data below reflect the safety of BRINSUPRI in adult and pediatric patients aged 12 years and older with non-cystic fibrosis bronchiectasis (NCFB). A total of 1721 patients with NCFB were randomized in a double-blind, placebo-controlled clinical trial of 52 weeks duration (ASPEN) [see Clinical Studies (14)]. The safety of BRINSUPRI was based on data from 1719 adult and pediatric patients aged 12 years and older who received at least one dose of BRINSUPRI or placebo. A total of 1156 patients received at least one dose of BRINSUPRI 10 mg or 25 mg orally once daily.

Table 1 shows the adverse reactions occurring at an incidence of ≥2% and higher in BRINSUPRI-treated patients compared to placebo in the safety population from ASPEN.

8 USE IN SPECIFIC POPULATIONS

USE IN SPECIFIC POPULATIONS SECTION

8.1 Pregnancy

PREGNANCY SECTION

SPL UNCLASSIFIED SECTION

Risk Summary

There are no available data on BRINSUPRI use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes.

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.

SPL UNCLASSIFIED SECTION

Data

SPL UNCLASSIFIED SECTION

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

LACTATION SECTION

SPL UNCLASSIFIED SECTION

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

PEDIATRIC USE SECTION

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

GERIATRIC USE SECTION

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)].

BRINSUPRI tablets are available for oral administration in strengths of 10 mg and 25 mg brensocatib with the following inactive ingredients: dibasic calcium phosphate dihydrate, glyceryl dibehenate, microcrystalline cellulose, silicon dioxide, and sodium starch glycolate. The film coating contains ferrosoferric oxide/black iron oxide, iron oxide yellow, and iron oxide red (10 mg) or ferrosoferric oxide/black iron oxide (25 mg), macrogol/PEG, polyvinyl alcohol-partially hydrolyzed, talc, and titanium dioxide.

12 CLINICAL PHARMACOLOGY

CLINICAL PHARMACOLOGY SECTION

12.1 Mechanism of Action

MECHANISM OF ACTION SECTION

Brensocatib is a competitive, reversible inhibitor of dipeptidyl peptidase 1 (DPP1). DPP1 activates pro-inflammatory neutrophil serine proteases (NSPs) during neutrophil maturation in the bone marrow. Activated NSPs are implicated in the pathogenesis of neutrophil-mediated NCFB inflammation. In cell-based assays, DPP1 inhibition by brensocatib reduces the activity of NSPs including neutrophil elastase, cathepsin G, and proteinase 3.

12.2 Pharmacodynamics

PHARMACODYNAMICS SECTION

Brensocatib prevents the activation of NSPs via DPP1 inhibition resulting in decreases in NSP activity in patients. In exploratory assays, brensocatib was associated with dose-dependent reductions in NSP activity in patients with NCFB.

SPL UNCLASSIFIED SECTION

Cardiac Electrophysiology

At concentrations approximately 2 times the steady state peak concentration of the maximum recommended daily dose of brensocatib in adult and adolescents with NCFB, clinically significant QTc interval prolongation was not observed.

12.3 Pharmacokinetics

PHARMACOKINETICS SECTION

Following once daily administration of brensocatib 10 mg, the estimated geometric mean (CV%) Cmax is 85.4 ng/mL (33%) and AUCtau is 1360 ng*h/mL (41%). Following once daily administration of brensocatib 25 mg, the estimated geometric mean (CV%) Cmax is 259 ng/mL (31%) and AUCtau is 4060 ng*h/mL (39%).

Brensocatib Cmax and AUCtau 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 Cmax increased by 5.1-fold and AUCtau increased by 5.3-fold. In healthy subjects, at steady state, Cmax increased by about 1.5-fold and AUCtau 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.

SPL UNCLASSIFIED SECTION

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 (Tmax) is 1.0-1.4 hours (0.5, 3.0 hours).

SPL UNCLASSIFIED SECTION

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).

SPL UNCLASSIFIED SECTION

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%.

SPL UNCLASSIFIED SECTION

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.

SPL UNCLASSIFIED SECTION

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.

SPL UNCLASSIFIED SECTION

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).

SPL UNCLASSIFIED SECTION

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 m2); or mild, moderate, or severe hepatic impairment (Child-Pugh Class A, B, or C).

13 NONCLINICAL TOXICOLOGY

NONCLINICAL TOXICOLOGY SECTION

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION

A two-year study in Han Wistar rats and a 6-month study in Tg.rasH2 transgenic mice were conducted to assess the carcinogenic potential of brensocatib. No evidence of tumorigenicity was observed in male or female rats at an exposure approximately 56 times the MRHD on an AUC basis. No evidence of tumorigenicity was observed in male and female Tg.rasH2 mice at oral doses up to 50 mg/kg/day, the highest dose tested. Brensocatib was negative for genotoxicity in the following assays: in vitro bacterial reverse mutation (Ames) assay, in vitro mouse lymphoma mutation assay, and in vivo micronucleus assay in rats.

Oral administration of brensocatib to male and female rats at up to 50 and 100 mg/kg/day, respectively, had no adverse effects on fertility and reproductive performance indices (150 and 231 times the MRHD on an AUC basis, respectively).

14 CLINICAL STUDIES

CLINICAL STUDIES SECTION

The efficacy of BRINSUPRI was evaluated in two randomized, double-blind, placebo-controlled, parallel-group, multicenter, multinational clinical trials (ASPEN [NCT04594369] and WILLOW [NCT03218917]).

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.

SPL UNCLASSIFIED SECTION

ASPEN

The primary efficacy endpoint in ASPEN was the annualized rate of PEx over the 52-week treatment period.

Pulmonary exacerbations were defined as worsening of 3 or more of the following major symptoms over 48 hours: increased cough, increased sputum volume or change in sputum consistency, increased sputum purulence, increased breathlessness, decreased exercise tolerance, fatigue and/or malaise, and hemoptysis, resulting in a healthcare provider's decision to prescribe systemic antibiotics. Pulmonary exacerbations were considered severe if requiring treatment with intravenous antibacterial drugs and/or resulted in hospitalization.

Treatment with BRINSUPRI 10 mg or 25 mg in patients with NCFB demonstrated reductions in the mean rate of PEx over 52 weeks compared with placebo (Figure 1). Table 3 provides the results of the annualized rate of PEx, and the results of the key secondary endpoints in ASPEN of time to first PEx, proportion of patients remaining exacerbation free throughout the 52-week treatment period, annualized rate of severe PEx, and the change from baseline in post-bronchodilator FEV1.
