HIGHLIGHTS OF PRESCRIBING INFORMATION

These highlights do not include all the information needed to use TRIKAFTA safely and effectively. See full prescribing information for TRIKAFTA.

TRIKAFTA™ (elexacaftor, tezacaftor and ivacaftor tablets; ivacaftor tablets), co-packaged for oral use
Initial U.S. Approval: 2019

INDICATIONS AND USAGE

TRIKAFTA is a combination of ivacaftor, a CFTR potentiator, tezacaftor, and elexacaftor indicated for the treatment of cystic fibrosis (CF) in patients aged 12 years and older who have at least one F508del mutation in the CFTR gene.

If the patient's genotype is unknown, an FDA-cleared CF mutation test should be used to confirm the presence of at least one F508del mutation. (1)

DOSAGE AND ADMINISTRATION

  • Adults and pediatric patients aged 12 years and older:
    • Morning dose: two elexacaftor 100 mg, tezacaftor 50 mg and ivacaftor 75 mg tablets
    • Evening dose: one ivacaftor 150 mg tablet
    • Morning and evening dose should be taken approximately 12 hours apart with fat-containing food. (2.1, 12.3)
  • Should not be used in patients with severe hepatic impairment. Use not recommended in patients with moderate hepatic impairment unless the benefit exceeds the risk. Reduce dose if used in patients with moderate hepatic impairment. Liver function tests should be closely monitored. (2.2, 5.1, 8.7, 12.3)
  • Reduce dose when co-administered with drugs that are moderate or strong CYP3A inhibitors. (2.3, 5.3, 7.2, 12.3)

DOSAGE FORMS AND STRENGTHS

  • Tablets: fixed dose combination containing elexacaftor 100 mg, tezacaftor 50 mg and ivacaftor 75 mg.

Co-packaged with:

  • Tablets: ivacaftor 150 mg. (3)

CONTRAINDICATIONS

None. (4)

WARNINGS AND PRECAUTIONS

  • Elevated liver function tests (ALT, AST or bilirubin): Liver function tests (ALT, AST, and bilirubin) should be assessed prior to initiating TRIKAFTA, every 3 months during the first year of treatment, and annually thereafter. In patients with a history of hepatobiliary disease or liver function test elevations, more frequent monitoring should be considered. Dosing should be interrupted in patients with ALT or AST >5 × upper limit of normal (ULN) or ALT or AST >3 × ULN with bilirubin >2 × ULN. Following resolution of transaminase elevations, consider the benefits and risks of resuming treatment. (5.1, 6)
  • Use with CYP3A inducers: Concomitant use with strong CYP3A inducers (e.g., rifampin, St. John's wort) significantly decrease ivacaftor exposure and are expected to decrease elexacaftor and tezacaftor exposure, which may reduce TRIKAFTA efficacy. Therefore, co-administration is not recommended. (5.2, 7.1, 12.3)
  • Cataracts: Non-congenital lens opacities/cataracts have been reported in pediatric patients treated with ivacaftor-containing regimens. Baseline and follow-up examinations are recommended in pediatric patients initiating TRIKAFTA treatment. (5.4, 8.4)

ADVERSE REACTIONS

The most common adverse drug reactions to TRIKAFTA (occurring in ≥5% of patients and at a frequency higher than placebo by ≥1%) were headache, upper respiratory tract infection, abdominal pain, diarrhea, rash, alanine aminotransferase increased, nasal congestion, blood creatine phosphokinase increased, aspartate aminotransferase increased, rhinorrhea, rhinitis, influenza, sinusitis and blood bilirubin increased. (6.1)

FULL PRESCRIBING INFORMATION

1 INDICATIONS AND USAGE

TRIKAFTA is indicated for the treatment of cystic fibrosis (CF) in patients aged 12 years and older who have at least one F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene.

If the patient's genotype is unknown, an FDA-cleared CF mutation test should be used to confirm the presence of at least one F508del mutation.

2 DOSAGE AND ADMINISTRATION

2.1 Dosing Information in Adults and Pediatric Patients Aged 12 Years and Older

The recommended dose is two tablets (each containing elexacaftor 100 mg, tezacaftor 50 mg and ivacaftor 75 mg) taken in the morning and one ivacaftor tablet (containing ivacaftor 150 mg) taken in the evening, approximately 12 hours apart. TRIKAFTA is for oral use. Instruct patients to swallow the tablets whole. TRIKAFTA should be taken with fat-containing food. Examples of meals or snacks that contain fat are those prepared with butter or oils or those containing eggs, cheeses, nuts, whole milk, or meats [see Clinical Pharmacology (12.3)].

If 6 hours or less have passed since the missed morning or evening dose, the patient should take the missed dose as soon as possible and continue on the original schedule.

If more than 6 hours have passed since:

  • the missed morning dose, the patient should take the missed dose as soon as possible and should not take the evening dose. The next scheduled morning dose should be taken at the usual time.
  • the missed evening dose, the patient should not take the missed dose. The next scheduled morning dose should be taken at the usual time.

Morning and evening doses should not be taken at the same time.

2.2 Dose Adjustment for Patients with Hepatic Impairment

TRIKAFTA has not been studied in patients with moderate or severe hepatic impairment. Patients with severe hepatic impairment should not be treated with TRIKAFTA. Use of TRIKAFTA is not recommended in patients with moderate hepatic impairment unless the benefit exceeds the risk. If used in patients with moderate hepatic impairment, TRIKAFTA should be used with caution and at a reduced dose (see Table 1). Liver function tests should be closely monitored [see Warnings and Precautions (5.1)].

No dose adjustment is recommended for patients with mild hepatic impairment [see Use in Specific Populations (8.7), Clinical Pharmacology (12.3), and Patient Counseling Information (17)].

    4 CONTRAINDICATIONS

    None.

    5 WARNINGS AND PRECAUTIONS

    5.1 Liver Function Test Elevations

    Elevated transaminases have been observed in patients with CF treated with TRIKAFTA. Bilirubin elevations have also been observed with TRIKAFTA treatment. Assessments of liver function tests (ALT, AST, and bilirubin) are recommended for all patients prior to initiating TRIKAFTA, every 3 months during the first year of treatment, and annually thereafter. For patients with a history of hepatobiliary disease or liver function test elevations, more frequent monitoring should be considered. In the event of significant elevations in liver function tests, e.g. ALT or AST >5 × the upper limit of normal (ULN) or ALT or AST >3 × ULN with bilirubin >2 × ULN, dosing should be interrupted and laboratory tests closely followed until the abnormalities resolve. Following the resolution of liver function test elevations, consider the benefits and risks of resuming treatment [see Adverse Reactions (6.1)].

    5.2 Concomitant Use with CYP3A Inducers

    Exposure to ivacaftor is significantly decreased and exposure to elexacaftor and tezacaftor are expected to decrease by the concomitant use of strong CYP3A inducers, which may reduce the therapeutic effectiveness of TRIKAFTA. Therefore, co-administration with strong CYP3A inducers is not recommended [see Drug Interactions (7.1), Clinical Pharmacology (12.3), and Patient Counseling Information (17)].

    5.3 Concomitant Use with CYP3A Inhibitors

    Exposure to elexacaftor, tezacaftor and ivacaftor are increased when co-administered with strong or moderate CYP3A inhibitors. Therefore, the dose of TRIKAFTA should be reduced when used concomitantly with moderate or strong CYP3A inhibitors [see Dosage and Administration (2.3), Drug Interactions (7.2), Clinical Pharmacology (12.3), and Patient Counseling Information (17)].

    5.4 Cataracts

    Cases of non-congenital lens opacities have been reported in pediatric patients treated with ivacaftor-containing regimens. Although other risk factors were present in some cases (such as corticosteroid use, exposure to radiation), a possible risk attributable to treatment with ivacaftor cannot be excluded. Baseline and follow-up ophthalmological examinations are recommended in pediatric patients initiating treatment with TRIKAFTA [see Use in Specific Populations (8.4) and Patient Counseling Information (17)].

    6 ADVERSE REACTIONS

    The following adverse reaction is discussed in greater detail in other sections of the label:

    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 profile of TRIKAFTA is based on data from 510 CF patients in two double-blind, controlled, Phase 3 trials of 24 weeks and 4 weeks treatment duration (Trials 1 and 2). Eligible patients were also able to participate in an open-label extension safety study (up to 96 weeks of TRIKAFTA). In the two controlled Phase 3 trials, a total of 257 patients aged 12 years and older received at least one dose of TRIKAFTA.

    In Trial 1, the proportion of patients who discontinued study drug prematurely due to adverse events was 1% for TRIKAFTA-treated patients and 0% for placebo-treated patients.

    Serious adverse reactions that occurred more frequently in TRIKAFTA-treated patients compared to placebo were rash (1% vs <1%) and influenza (1% vs 0). There were no deaths in Trials 1 and 2.

    Table 3 shows adverse reactions occurring in ≥5% of TRIKAFTA-treated patients and higher than placebo by ≥1% in the 24-week placebo-controlled, parallel-group Phase 3 trial (Trial 1).

    Additional adverse reactions that occurred in TRIKAFTA-treated patients at a frequency of 2 to <5% and higher than placebo by ≥1% include the following: Flatulence, abdominal distension, conjunctivitis, pharyngitis, respiratory tract infection, tonsillitis, urinary tract infection, c-reactive protein increased, hypoglycemia, dizziness, dysmenorrhea, acne, eczema, and pruritus.

    Rash Events

    In Trial 1, the overall incidence of rash events was 10% in TRIKAFTA-treated and 5% in placebo-treated patients (see Table 3). The incidence of rash events was higher in female TRIKAFTA-treated patients (16%) than in male TRIKAFTA-treated patients (5%).

    Hormonal contraceptives may play a role in the occurrence of rash. For patients taking hormonal contraceptives who develop rash, consider interrupting TRIKAFTA and hormonal contraceptives. Following the resolution of rash, consider resuming TRIKAFTA without the hormonal contraceptives. If rash does not recur, resumption of hormonal contraceptives can be considered.

    Laboratory and Vital Sign Abnormalities

    Liver Function Test Elevations

    In Trial 1, the incidence of maximum transaminase (ALT or AST) >8, >5, or >3 × ULN was 1%, 2%, and 8% in TRIKAFTA-treated patients and 1%, 1%, and 5% in placebo-treated patients. The incidence of adverse reactions of transaminase elevations (AST and/or ALT) was 11% in TRIKAFTA-treated patients and 4% placebo-treated patients.

    In Trial 1, the incidence of maximum total bilirubin elevation >2 × ULN was 4% in TRIKAFTA-treated patients and <1% in placebo-treated patients. Maximum indirect and direct bilirubin elevations >1.5 × ULN occurred in 11% and 3% of TRIKAFTA-treated patients, respectively. No TRIKAFTA-treated patients developed maximum direct bilirubin elevation >2 × ULN.

    Increased Creatine Phosphokinase

    In Trial 1, the incidence of maximum creatine phosphokinase elevation >5 × ULN was 10% in TRIKAFTA-treated and 5% in placebo-treated patients. Among the TRIKAFTA-treated patients with creatine phosphokinase elevation >5 × ULN, 14% (3/21) required treatment interruption and none discontinued treatment.

    Increased Blood Pressure

    In Trial 1, the maximum increase from baseline in mean systolic and diastolic blood pressure was 3.5 mmHg and 1.9 mmHg, respectively for TRIKAFTA-treated patients (baseline: 113 mmHg systolic and 69 mmHg diastolic) and 0.9 mmHg and 0.5 mmHg, respectively for placebo-treated patients (baseline: 114 mmHg systolic and 70 mmHg diastolic).

    The proportion of patients who had systolic blood pressure >140 mmHg and 10 mmHg increase from baseline on at least two occasions was 4% in TRIKAFTA-treated patients and 1% in placebo-treated patients. The proportion of patients who had diastolic blood pressure >90 mmHg and 5 mmHg increase from baseline on at least two occasions was 1% in TRIKAFTA-treated patients and 2% in placebo-treated patients.

    With the exception of sex differences in rash, the safety profile of TRIKAFTA was generally similar across all subgroups of patients, including analysis by age, sex, baseline percent predicted FEV1 (ppFEV1), and geographic regions.

    The safety profile for the CF patients enrolled in Trial 2 was similar to that observed in Trial 1.

    7 DRUG INTERACTIONS

    Potential for other drugs to affect elexacaftor/tezacaftor/ivacaftor

    7.1 Inducers of CYP3A

    Elexacaftor, tezacaftor and ivacaftor are substrates of CYP3A (ivacaftor is a sensitive substrate of CYP3A). Concomitant use of CYP3A inducers may result in reduced exposures and thus reduced TRIKAFTA efficacy. Co-administration of ivacaftor with rifampin, a strong CYP3A inducer, significantly decreased ivacaftor area under the curve (AUC) by 89%. Elexacaftor and tezacaftor exposures are expected to decrease during co-administration with strong CYP3A inducers. Therefore, co-administration of TRIKAFTA with strong CYP3A inducers is not recommended [see Warnings and Precautions (5.2), Clinical Pharmacology (12.3), and Patient Counseling Information (17)].

    Examples of strong CYP3A inducers include:

    • rifampin, rifabutin, phenobarbital, carbamazepine, phenytoin, and St. John's wort (Hypericum perforatum)

    7.2 Inhibitors of CYP3A

    Co-administration with itraconazole, a strong CYP3A inhibitor, increased elexacaftor AUC by 2.8-fold and tezacaftor AUC by 4.0 to 4.5-fold. When co-administered with itraconazole and ketoconazole, ivacaftor AUC increased by 15.6-fold and 8.5-fold, respectively. The dosage of TRIKAFTA should be reduced when co-administered with strong CYP3A inhibitors [see Dosage and Administration (2.3), Warnings and Precautions (5.3), Clinical Pharmacology (12.3), and Patient Counseling Information (17)].

    Examples of strong CYP3A inhibitors include:

    • ketoconazole, itraconazole, posaconazole, and voriconazole
    • telithromycin and clarithromycin

    Simulations indicated that co-administration with moderate CYP3A inhibitors may increase elexacaftor and tezacaftor AUC by approximately 1.9 to 2.3-fold and 2.1-fold, respectively. Co-administration of fluconazole increased ivacaftor AUC by 2.9-fold. The dosage of TRIKAFTA should be reduced when co administered with moderate CYP3A inhibitors [see Dosage and Administration (2.3), Warnings and Precautions (5.3), Clinical Pharmacology (12.3), and Patient Counseling Information (17)].

    Examples of moderate CYP3A inhibitors include:

    • fluconazole
    • erythromycin

    Co-administration of TRIKAFTA with grapefruit juice, which contains one or more components that moderately inhibit CYP3A, may increase exposure of elexacaftor, tezacaftor and ivacaftor; therefore, food or drink containing grapefruit should be avoided during treatment with TRIKAFTA [see Dosage and Administration (2.3), and Patient Counseling Information (17)].

    7.3 Ciprofloxacin

    Ciprofloxacin had no clinically relevant effect on the exposure of tezacaftor or ivacaftor and is not expected to affect the exposure of elexacaftor. Therefore, no dose adjustment is necessary during concomitant administration of TRIKAFTA with ciprofloxacin [see Clinical Pharmacology (12.3)].

    Potential for elexacaftor/tezacaftor/ivacaftor to affect other drugs

    7.4 CYP2C9 Substrates

    Ivacaftor may inhibit CYP2C9; therefore, monitoring of the international normalized ratio (INR) during co administration of TRIKAFTA with warfarin is recommended. Other medicinal products for which exposure may be increased by TRIKAFTA include glimepiride and glipizide; these medicinal products should be used with caution [see Clinical Pharmacology (12.3)].

    7.5 Transporters

    Co-administration of ivacaftor or tezacaftor/ivacaftor with digoxin, a sensitive P-gp substrate, increased digoxin AUC by 1.3-fold, consistent with weak inhibition of P-gp by ivacaftor. Administration of TRIKAFTA may increase systemic exposure of medicinal products that are sensitive substrates of P-gp, which may increase or prolong their therapeutic effect and adverse reactions. When used concomitantly with digoxin or other substrates of P-gp with a narrow therapeutic index such as cyclosporine, everolimus, sirolimus, and tacrolimus, caution and appropriate monitoring should be used [see Clinical Pharmacology (12.3)].

    Elexacaftor and M23-ELX inhibit uptake by OATP1B1 and OATP1B3 in vitro. Co-administration of TRIKAFTA may increase exposures of medicinal products that are substrates of these transporters, such as statins, glyburide, nateglinide and repaglinide. When used concomitantly with substrates of OATP1B1 or OATP1B3, caution and appropriate monitoring should be used [see Clinical Pharmacology (12.3)]. Bilirubin is an OATP1B1 and OATP1B3 substrate.

    7.6 Hormonal Contraceptives

    TRIKAFTA has been studied with ethinyl estradiol/levonorgestrel and was found to have no clinically relevant effect on the exposures of the oral contraceptive. TRIKAFTA is not expected to have an impact on the efficacy of oral contraceptives.

    8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    There are limited and incomplete human data from clinical trials on the use of TRIKAFTA or its individual components, elexacaftor, tezacaftor and ivacaftor, in pregnant women to inform a drug-associated risk. Although there are no animal reproduction studies with the concomitant administration of elexacaftor, tezacaftor and ivacaftor, separate reproductive and developmental studies were conducted with each active component of TRIKAFTA in pregnant rats and rabbits.

    In animal embryo fetal development (EFD) studies oral administration of elexacaftor to pregnant rats and rabbits during organogenesis demonstrated no teratogenicity or adverse developmental effects at doses that produced maternal exposures up to approximately 2 times the exposure at the maximum recommended human dose (MRHD) in rats and 4 times the MRHD in rabbits [based on summed AUCs of elexacaftor and its metabolite (for rat) and AUC of elexacaftor (for rabbit)]. Oral administration of tezacaftor to pregnant rats and rabbits during organogenesis demonstrated no teratogenicity or adverse developmental effects at doses that produced maternal exposures up to approximately 3 times the exposure at the MRHD in rats and 0.2 times the MRHD in rabbits (based on summed AUCs of tezacaftor and M1-TEZ). Oral administration of ivacaftor to pregnant rats and rabbits during organogenesis demonstrated no teratogenicity or adverse developmental effects at doses that produced maternal exposures up to approximately 5 and 14 times the exposure at the MRHD, respectively [based on summed AUCs of ivacaftor and its metabolites (for rat) and AUC of ivacaftor (for rabbit)]. No adverse developmental effects were observed after oral administration of elexacaftor, tezacaftor or ivacaftor to pregnant rats from the period of organogenesis through lactation at doses that produced maternal exposures approximately 1 time, approximately 1 time and 3 times the exposures at the MRHD, respectively [based on summed AUCs of parent and metabolite(s)] (see Data).

    The 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% to 4% and 15% to 20%, respectively.

    Data

    Animal Data

    Elexacaftor

    In an EFD study in pregnant rats dosed during the period of organogenesis from gestation Days 6-17, elexacaftor was not teratogenic and did not affect fetal survival at exposures up to 9 times the MRHD (based on summed AUC for elexacaftor and its metabolite at maternal doses up to 40 mg/kg/day). Lower mean fetal body weights were observed at doses ≥25 mg/kg/day that produced maternal exposures ≥4 times the MRHD. In an EFD study in pregnant rabbits dosed during the period of organogenesis from gestation Days 7-20, elexacaftor was not teratogenic at exposures up to 4 times the MRHD (based on AUC of elexacaftor at maternal doses up to 125 mg/kg/day). In a pre- and postnatal development (PPND) study in pregnant rats dosed from gestation Day 6 through lactation Day 18, elexacaftor did not cause developmental defects in pups at maternal doses up to 10 mg/kg/day (approximately 1 time the MRHD based on summed AUCs of elexacaftor and its metabolite). Placental transfer of elexacaftor was observed in pregnant rats.

    Tezacaftor

    In an EFD study in pregnant rats dosed during the period of organogenesis from gestation Days 6-17 and in pregnant rabbits dosed during the period of organogenesis from gestation Days 7-20, tezacaftor was not teratogenic and did not affect fetal development or survival at exposures up to 3 and 0.2 times, respectively the MRHD (based on summed AUCs of tezacaftor and M1-TEZ). Lower fetal body weights were observed in rabbits at a maternally toxic dose that produced exposures approximately 1 time the MRHD (based on summed AUCs of tezacaftor and M1-TEZ at a maternal dose of 50 mg/kg/day). In a PPND study in pregnant rats dosed from gestation Day 6 through lactation Day 18, tezacaftor had no adverse developmental effects on pups at an exposure of approximately 1 time the MRHD (based on summed AUCs for tezacaftor and M1-TEZ at a maternal dose of 25 mg/kg/day). Decreased fetal body weights and early developmental delays in pinna detachment, eye opening, and righting reflex occurred at a maternally toxic dose (based on maternal weight loss) that produced exposures approximately 1 time the exposure at the MRHD (based on summed AUCs for tezacaftor and M1-TEZ at a maternal oral dose of 50 mg/kg/day). Placental transfer of tezacaftor was observed in pregnant rats.

    Ivacaftor

    In an EFD study in pregnant rats dosed during the period of organogenesis from gestation Days 7-17 and in pregnant rabbits dosed during the period of organogenesis from gestation Days 7-19, ivacaftor was not teratogenic and did not affect fetal survival at exposures up to 5 and 14 times, respectively, the MRHD [based on summed AUCs of ivacaftor and its metabolites (for rat) and AUC of ivacaftor (for rabbit)]. In a PPND study in pregnant rats dosed from gestation Day 7 through lactation Day 20, ivacaftor had no effects on delivery or growth and development of offspring at exposures up to 3 times the MRHD (based on summed AUCs for ivacaftor and its metabolites at maternal oral doses up to 100 mg/kg/day). Decreased fetal body weights were observed at a maternally toxic dose that produced exposures 5 times the MRHD (based on summed AUCs of ivacaftor and its metabolites). Placental transfer of ivacaftor was observed in pregnant rats and rabbits.

    8.2 Lactation

    Risk Summary

    There is no information regarding the presence of elexacaftor, tezacaftor, or ivacaftor in human milk, the effects on the breastfed infant, or the effects on milk production. Elexacaftor, tezacaftor, and ivacaftor are excreted into the milk of lactating rats (see Data). The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for TRIKAFTA and any potential adverse effects on the breastfed child from TRIKAFTA or from the underlying maternal condition.

    Data

    Elexacaftor

    Lacteal excretion of elexacaftor in rats was demonstrated following a single oral dose (10 mg/kg) of 14C-elexacaftor administered 6 to 10 days postpartum to lactating dams. Exposure of 14C-elexacaftor in milk was approximately 0.4 times the value observed in plasma (based on AUC0-72h).

    Tezacaftor

    Lacteal excretion of tezacaftor in rats was demonstrated following a single oral dose (30 mg/kg) of 14C-tezacaftor administered 6 to 10 days postpartum to lactating dams. Exposure of 14C-tezacaftor in milk was approximately 3 times higher than in plasma (based on AUC0-72h).

    Ivacaftor

    Lacteal excretion of ivacaftor in rats was demonstrated following a single oral dose (100 mg/kg) of 14C-ivacaftor administered 9 to 10 days postpartum to lactating dams. Exposure of 14C-ivacaftor in milk was approximately 1.5 times higher than in plasma (based on AUC0-24h).

    8.4 Pediatric Use

    The safety and effectiveness of TRIKAFTA for the treatment of CF in pediatric patients 12 years and older who have at least one F508del mutation in the CFTR gene has been established. Use of TRIKAFTA for this indication was supported by evidence from two adequate and well-controlled studies in CF patients 12 years and older (Trial 1 and Trial 2) [see Clinical Studies (14)]. In these trials, a total of 72 adolescents (aged 12 to 17 years) received TRIKAFTA, including:

    The safety and effectiveness of TRIKAFTA in patients with CF younger than 12 years of age have not been established.

    Juvenile Animal Toxicity Data

    Findings of cataracts were observed in juvenile rats dosed from postnatal Day 7 through 35 with ivacaftor dose levels of 10 mg/kg/day and higher (0.24 times the MRHD based on systemic exposure of ivacaftor and its metabolites). This finding has not been observed in older animals [see Warnings and Precautions (5.4) and Patient Counseling Information (17)].

    8.5 Geriatric Use

    Clinical studies of TRIKAFTA did not include any patients aged 65 years and older.

    8.6 Renal Impairment

    TRIKAFTA has not been studied in patients with severe renal impairment or end-stage renal disease. No dosage adjustment is recommended in patients with mild (eGFR 60 to <90 mL/min/1.73 m2) or moderate (eGFR 30 to <60 mL/min/1.73 m2) renal impairment. Use with caution in patients with severe (eGFR <30 mL/min/1.73 m2) renal impairment or end-stage renal disease [see Clinical Pharmacology (12.3)].

    8.7 Hepatic Impairment

    Patients with severe hepatic impairment (Child-Pugh Class C) should not be treated with TRIKAFTA. Use of TRIKAFTA is not recommended in patients with moderate hepatic impairment (Child-Pugh Class B) unless the benefit exceeds the risk. If used in patients with moderate hepatic impairment, TRIKAFTA should be used with caution and at a reduced dose. Liver function tests should be closely monitored. No dose modification is recommended for patients with mild hepatic impairment (Child-Pugh Class A) [see Dosage and Administration (2.2), Warnings and Precautions (5.1), Clinical Pharmacology (12.3), and Patient Counseling Information (17)].

    8.8 Patients with Severe Lung Dysfunction

    Trial 1 included a total of 18 patients receiving TRIKAFTA with ppFEV1 <40 at baseline. The safety and efficacy in this subgroup were comparable to those observed in the overall population.

    10 OVERDOSAGE

    Chemical Structure

    12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Elexacaftor and tezacaftor bind to different sites on the CFTR protein and have an additive effect in facilitating the cellular processing and trafficking of F508del-CFTR to increase the amount of CFTR protein delivered to the cell surface compared to either molecule alone. Ivacaftor potentiates the channel open probability (or gating) of the CFTR protein at the cell surface.

    The combined effect of elexacaftor, tezacaftor and ivacaftor is increased quantity and function of F508del-CFTR at the cell surface, resulting in increased CFTR activity as measured by CFTR mediated chloride transport.

    12.2 Pharmacodynamics

    Sweat Chloride Evaluation

    In Trial 1 (patients with an F508del mutation on one allele and a mutation on the second allele that results in either no CFTR protein or a CFTR protein that is not responsive ivacaftor and tezacaftor/ivacaftor), a reduction in sweat chloride was observed from baseline at Week 4 and sustained through the 24-week treatment period [see Clinical Studies (14.1)]. In Trial 2 (patients homozygous for the F508del mutation), a reduction in sweat chloride was observed from baseline at Week 4 [see Clinical Studies (14.2)].

    Cardiac Electrophysiology

    At doses up to 2 times the maximum recommended dose of elexacaftor and 3 times the maximum recommended dose of tezacaftor and ivacaftor, the QT/QTc interval in healthy subjects was not prolonged to any clinically relevant extent.

    12.3 Pharmacokinetics

    The pharmacokinetics of elexacaftor, tezacaftor and ivacaftor are similar between healthy adult subjects and patients with CF. The pharmacokinetic parameters for elexacaftor, tezacaftor, and ivacaftor in patients with CF aged 12 years and older are shown in Table 4.

    Specific Populations

    Pediatric patients 12 to less than 18 years of age

    The following conclusions about exposures between adults and the pediatric population are based on population pharmacokinetic (PK) analyses.

    Following oral administration of TRIKAFTA to patients 12 to less than 18 years of age (elexacaftor 200 mg QD/tezacaftor 100 mg QD/ivacaftor 150 mg Q12h), the mean (±SD) AUCss was 149 (38.7) mcg∙h/mL, 97.1 (23.7) mcg∙h/mL and 10.6 (3.35) mcg∙h/mL, respectively for elexacaftor, tezacaftor and ivacaftor, similar to the AUCss in adult patients.

    Patients with Renal Impairment

    Renal excretion of elexacaftor, tezacaftor, and ivacaftor is minimal. Elexacaftor alone or in combination with tezacaftor and ivacaftor has not been studied in patients with severe (eGFR <30 mL/min/1.73 m2) renal impairment or end stage renal disease. Based on population PK analyses, the clearance of elexacaftor and tezacaftor was similar in patients with mild (eGFR 60 to <90 mL/min/1.73 m2) or moderate (eGFR 30 to <60 mL/min/1.73 m2) renal impairment relative to patients with normal renal function [see Use in Specific Populations (8.6)].

    Patients with Hepatic Impairment

    Elexacaftor alone or in combination with tezacaftor and ivacaftor has not been studied in subjects with hepatic impairment. Similar to tezacaftor and ivacaftor, higher exposure of elexacaftor is expected in patients with moderate (Child-Pugh Class B, score 7 to 9) and severe hepatic impairment (Child-Pugh Class B, score 10-15) [see Dosage and Administration (2.2), Use in Specific Populations (8.7), and Patient Counseling Information (17)].

    Tezacaftor and ivacaftor

    Following multiple doses of tezacaftor and ivacaftor for 10 days, subjects with moderately impaired hepatic function had an approximately 36% higher AUC and a 10% higher in Cmax for tezacaftor, and a 1.5-fold higher AUC but similar Cmax for ivacaftor compared with healthy subjects matched for demographics.

    Ivacaftor

    In a study with ivacaftor alone, subjects with moderately impaired hepatic function had similar ivacaftor Cmax, but an approximately 2.0-fold higher ivacaftor AUC0-∞ compared with healthy subjects matched for demographics.

    Male and Female Patients

    Based on population PK analysis, the exposures of elexacaftor, tezacaftor and ivacaftor are similar in males and females.

    Drug Interactions Studies

    Drug interaction studies were performed with elexacaftor, tezacaftor and/or ivacaftor and other drugs likely to be co-administered or drugs commonly used as probes for pharmacokinetic interaction studies [see Drug Interactions (7)].

    Potential for Elexacaftor, Tezacaftor and/or Ivacaftor to Affect Other Drugs

    Based on in vitro results, elexacaftor and tezacaftor have a low potential to inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6 and CYP3A4, whereas ivacaftor has the potential to inhibit CYP2C8, CYP2C9, and CYP3A. However, clinical studies showed that the combination regimen of tezacaftor/ivacaftor is not an inhibitor of CYP3A and ivacaftor is not an inhibitor of CYP2C8 or CYP2D6.

    Based on in vitro results, elexacaftor, tezacaftor and ivacaftor are not likely to induce CYP3A, CYP1A2 and CYP2B6.

    Based on in vitro results, elexacaftor and tezacaftor have a low potential to inhibit the transporter P-gp, while ivacaftor has the potential to inhibit P-gp. Co-administration of tezacaftor/ivacaftor with digoxin, a sensitive P-gp substrate, increased digoxin exposure by 1.3-fold in a clinical study. Based on in vitro results, elexacaftor and M23-ELX may inhibit OATP1B1 and OATP1B3 uptake. Tezacaftor has a low potential to inhibit BCRP, OCT2, OAT1, or OAT3. Ivacaftor is not an inhibitor of the transporters OCT1, OCT2, OAT1, or OAT3.

    The effects of elexacaftor, tezacaftor and/or ivacaftor on the exposure of co-administered drugs are shown in Table 5 [see Drug Interactions (7)].

    Potential for Other Drugs to Affect Elexacaftor, Tezacaftor and/or Ivacaftor

    In vitro studies showed that elexacaftor, tezacaftor, and ivacaftor are all metabolized by CYP3A. Exposure to elexacaftor, tezacaftor and ivacaftor may be reduced by concomitant CYP3A inducers and increased by concomitant CYP3A inhibitors.

    In vitro studies showed that elexacaftor and tezacaftor are substrates for the efflux transporter P-gp, but ivacaftor is not. Elexacaftor and ivacaftor are not substrates for OATP1B1 or OATP1B3; tezacaftor is a substrate for OATP1B1, but not OATP1B3. Tezacaftor is a substrate for BCRP.

    The effects of co-administered drugs on the exposure of elexacaftor, tezacaftor and/or ivacaftor are shown in Table 6 [see Dosage and Administration (2.3) and Drug Interactions (7)].

    13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    No studies of carcinogenicity, mutagenicity, or impairment of fertility were conducted with the combination of elexacaftor, tezacaftor and ivacaftor; however, separate studies of elexacaftor, tezacaftor and ivacaftor are described below.

    Elexacaftor

    A 6-month study in Tg.rasH2 transgenic mice showed no evidence of tumorigenicity at 50 mg/kg/day dose, the highest dose tested.

    Elexacaftor was negative for genotoxicity in the following assays: Ames test for bacterial gene mutation, in vitro mammalian cell micronucleus assay in TK6 cells, and in vivo mouse micronucleus test.

    Elexacaftor did not cause reproductive system toxicity in male rats at 55 mg/kg/day and female rats at 25 mg/kg/day, equivalent to approximately 6 times and 4 times the MRHD, respectively (based on summed AUCs of elexacaftor and its metabolite). Elexacaftor did not cause embryonic toxicity at 35 mg/kg/day which was the highest dose tested, equivalent to approximately 7 times the MHRD (based on summed AUCs of elexacaftor and its metabolite). Lower male and female fertility, male copulation, and female conception indices were observed in males at 75 mg/kg/day and females at 35 mg/kg/day, equivalent to approximately 6 times and 7 times, respectively, the MRHD (based on summed AUCs of elexacaftor and its metabolite).

    Tezacaftor

    A 2-year study in Sprague-Dawley rats and a 6-month study in Tg.rasH2 transgenic mice were conducted to assess the carcinogenic potential of tezacaftor. No evidence of tumorigenicity from tezacaftor was observed in male and female rats at oral doses up to 50 and 75 mg/kg/day (approximately 1 and 2 times the MRHD based on summed AUCs of tezacaftor and its metabolites in males and females, respectively). No evidence of tumorigenicity was observed in male and female Tg.rasH2 transgenic mice at tezacaftor doses up to 500 mg/kg/day.

    Tezacaftor was negative for genotoxicity in the following assays: Ames test for bacterial gene mutation, in vitro chromosomal aberration assay in Chinese hamster ovary cells, and in vivo mouse micronucleus test.

    There were no effects on male or female fertility and early embryonic development in rats at oral tezacaftor doses up to 100 mg/kg/day (approximately 3 times the MRHD based on summed AUC of tezacaftor and M1-TEZ).

    Ivacaftor

    Two-year studies were conducted in CD-1 mice and Sprague-Dawley rats to assess the carcinogenic potential of ivacaftor. No evidence of tumorigenicity from ivacaftor was observed in mice or rats at oral doses up to 200 mg/kg/day and 50 mg/kg/day, respectively (approximately equivalent to 2 and 7 times the MRHD, respectively, based on summed AUCs of ivacaftor and its metabolites).

    Ivacaftor was negative for genotoxicity in the following assays: Ames test for bacterial gene mutation, in vitro chromosomal aberration assay in Chinese hamster ovary cells, and in vivo mouse micronucleus test.

    Ivacaftor impaired fertility and reproductive performance indices in male and female rats at 200 mg/kg/day (approximately 7 and 5 times, respectively, the MRHD based on summed AUCs of ivacaftor and its metabolites). Increases in prolonged diestrus were observed in females at 200 mg/kg/day. Ivacaftor also increased the number of females with all nonviable embryos and decreased corpora lutea, implantations, and viable embryos in rats at 200 mg/kg/day (approximately 5 times the MRHD based on summed AUCs of ivacaftor and its metabolites) when dams were dosed prior to and during early pregnancy. These impairments of fertility and reproductive performance in male and female rats at 200 mg/kg/day were attributed to severe toxicity.

    14 CLINICAL STUDIES

    Efficacy:

    The efficacy of TRIKAFTA in patients with CF aged 12 years and older was evaluated in two Phase 3, double blind, controlled trials (Trials 1 and 2).

    Trial 1 was a 24-week, randomized, double-blind, placebo-controlled study in patients who had an F508del mutation on one allele and a mutation on the second allele that results in either no CFTR protein or a CFTR protein that is not responsive to ivacaftor and tezacaftor/ivacaftor. An interim analysis was planned when at least 140 patients completed Week 4 and at least 100 patients completed Week 12.

    Trial 2 was a 4-week, randomized, double-blind, active-controlled study in patients who are homozygous for the F508del mutation. Patients received tezacaftor 100 mg qd/ivacaftor 150 mg q12hr during a 4-week open-label run-in period and were then randomized and dosed to receive TRIKAFTA or tezacaftor 100 mg qd/ivacaftor 150 mg q12hr during a 4-week double-blind treatment period.

    Patients in Trials 1 and 2 had a confirmed diagnosis of CF and at least one F508del mutation. Patients discontinued any previous CFTR modulator therapies,

    but continued on their other standard-of-care CF therapies (e.g., bronchodilators, inhaled antibiotics, dornase alfa, and hypertonic saline). Patients had a ppFEV1 at screening between 40-90%. Patients with a history of colonization with organisms associated with a more rapid decline in pulmonary status, including but not limited to Burkholderia cenocepacia, Burkholderia dolosa, or Mycobacterium abscessus, or who had an abnormal liver function test at screening (ALT, AST, ALP, or GGT ≥3 × ULN, or total bilirubin ≥2 × ULN), were excluded from the trials. Patients in Trials 1 and 2 were eligible to roll over into a 96-week open-label extension study.

    14.1 Trial 1

    Trial 1 evaluated 403 patients (200 TRIKAFTA, 203 placebo) with CF aged 12 years and older (mean age 26.2 years). The mean ppFEV1 at baseline was 61.4% (range: 32.3%, 97.1%). The primary endpoint assessed at the time of interim analysis was mean absolute change in ppFEV1 from baseline at Week 4. The final analysis tested all key secondary endpoints in the 403 patients who completed the 24-week study participation, including absolute change in ppFEV1 from baseline through Week 24; absolute change in sweat chloride from baseline at Week 4 and through Week 24; number of pulmonary exacerbations through Week 24; absolute change in BMI from baseline at Week 24, and absolute change in CFQ-R Respiratory Domain Score (a measure of respiratory symptoms relevant to patients with CF, such as cough, sputum production, and difficulty breathing) from baseline at Week 4 and through Week 24.

    Of the 403 patients included in the interim analysis, the treatment difference between TRIKAFTA and placebo for the mean absolute change from baseline in ppFEV1 at Week 4 was 13.8 percentage points (95% CI: 12.1, 15.4; P<0.0001).

    The treatment difference between TRIKAFTA and placebo for mean absolute change in ppFEV1 from baseline through Week 24 was 14.3 percentage points (95% CI: 12.7, 15.8; P<0.0001). Mean improvement in ppFEV1 was observed at the first assessment on Day 15 and sustained through the 24-week treatment period (see Figure 1). Improvements in ppFEV1 were observed regardless of age, baseline ppFEV1, sex, and geographic region.

    See Table 7 for a summary of primary and key secondary outcomes in Trial 1.

    14.2 Trial 2

    Trial 2 evaluated 107 patients with CF aged 12 years and older (mean age 28.4 years). The mean ppFEV1 at baseline, following the 4-week open-label run-in period with tezacaftor/ivacaftor was 60.9% (range: 35.0%, 89.0%). The primary endpoint was mean absolute change in ppFEV1 from baseline at Week 4 of the double-blind treatment period. The key secondary efficacy endpoints were absolute change in sweat chloride and CFQ-R Respiratory Domain Score from baseline at Week 4. Treatment with TRIKAFTA compared to tezacaftor/ivacaftor resulted in a statistically significant improvement in ppFEV1 of 10.0 percentage points (95% CI: 7.4, 12.6; P<0.0001). Mean improvement in ppFEV1 was observed at the first assessment on Day 15. Improvements in ppFEV1 were observed regardless of age, sex, baseline ppFEV1, and geographic region. See Table 8 for a summary of primary and key secondary outcomes.

    17 PATIENT COUNSELING INFORMATION

    Advise the patient to read the FDA-approved patient labeling (Patient Information).

    Liver Function Test Elevations and Monitoring

    Inform patients that elevation in transaminases has occurred in patients treated with TRIKAFTA. Elevations in bilirubin have also been observed with TRIKAFTA treatment. Liver function tests (ALT, AST, and bilirubin) should be assessed prior to initiating TRIKAFTA, every 3 months during the first year of treatment, and annually thereafter. More frequent monitoring should be considered in patients with a history of hepatobiliary disease or liver function test elevations [see Warnings and Precautions (5.1)].

    Drug Interactions with CYP3A Inducers and Inhibitors

    Ask patients to tell you all the medications they are taking including any herbal supplements or vitamins. Co-administration of TRIKAFTA with strong CYP3A inducers (e.g., rifampin, St. John's wort) is not recommended, as they may reduce the efficacy of TRIKAFTA. Dose reduction to two elexacaftor/tezacaftor/ivacaftor tablets twice a week, taken approximately 3 to 4 days apart is recommended when co-administered with strong CYP3A inhibitors, such as ketoconazole. Advise the patient not to take the evening dose of ivacaftor. Dose reduction to two elexacaftor/tezacaftor/ivacaftor tablets and one ivacaftor tablet taken on alternate days is recommended when co-administered with moderate CYP3A inhibitors, such as fluconazole. Advise the patient not to take the evening dose of ivacaftor. Food or drink containing grapefruit should be avoided [see Dosage and Administration (2), Warnings and Precautions (5), Drug Interactions (7), and Clinical Pharmacology (12.3)].

    Use in Patients with Hepatic Impairment

    TRIKAFTA has not been studied in patients with moderate or severe hepatic impairment. Inquire and/or assess whether patients have liver impairment. Patients with severe hepatic impairment (Child-Pugh Class C, score 10-15) should not be treated with TRIKAFTA. Use of TRIKAFTA is not recommended in patients with moderate hepatic impairment (Child-Pugh Class B, score 7-9) unless the benefit exceeds the risk. If used in patients with moderate hepatic impairment, TRIKAFTA should be used with caution and at a reduced dose. Liver function tests should be closely monitored. No dose adjustment is recommended for patients with mild hepatic impairment (Child-Pugh Class A, score 5-6) [see Dosage and Administration (2.2), Warnings and Precautions (5.1), Use in Specific Populations (8.7), and Clinical Pharmacology (12.3)].

    Cataracts

    Inform patients that abnormality of the eye lens (cataract) has been noted in some children and adolescents receiving ivacaftor-containing regimens. Baseline and follow-up ophthalmological examinations should be performed in pediatric patients initiating treatment with TRIKAFTA [see Warnings and Precautions (5.4) and Use in Specific Populations (8.4)].

    Administration

    Inform patients that TRIKAFTA is best absorbed by the body when taken with food that contains fat. A typical CF diet will satisfy this requirement. Examples include eggs, butter, peanut butter, whole-milk dairy products (such as whole milk, cheese, and yogurt), etc. [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3)].

    Patients should be informed about what to do in the event they miss a dose of elexacaftor/tezacaftor/ivacaftor tablets or ivacaftor tablet:

    • If 6 hours or less have passed since the missed morning or evening dose is usually taken, patients should be instructed to take the prescribed dose with fat-containing food as soon as possible.
    • If more than 6 hours have passed since:
      • the time the morning dose is usually taken, patients should be instructed to take the morning dose as soon as possible, and not take the evening dose. Patients should take the next scheduled morning dose at the usual time.
      • the time the evening dose is usually taken, patients should be instructed to not take the missed evening dose. Patients should take the next scheduled morning dose at the usual time.
    • Patients should be instructed to not take the morning and evening doses at the same time.
    • Patients should be advised to contact their health care provider if they have questions.
