Dosage and administration

Take with food. Recommended dosage: 801 mg three times daily (2403 mg/day). ( 2 ) Upon initiation of treatment, titrate to the full dosage of 2403 mg/day over a 14-day period as follows: Treatment days Dosage Days 1 through 7 267 mg three times daily (801 mg/day) Days 8 through 14 534 mg three times daily (1602 mg/day) Days 15 onward 801 mg three times daily (2403 mg/day) Consider temporary dosage reduction, treatment interruption, or discontinuation for management of adverse reactions. ( 2.3 , 5.1 , 5.2 , 5.3 , 5.4 ) Prior to treatment, conduct liver function tests. ( 2.1 ) 2.1 Testing Prior to ESBRIET Administration Conduct liver function tests prior to initiating treatment with ESBRIET [see Warnings and Precautions (5.1) ]. 2.2 Recommended Dosage The recommended daily maintenance dosage of ESBRIET is 801 mg three times daily for a total of 2403 mg/day. Doses should be taken with food at the same time each day. Upon initiation of treatment, titrate to the full dosage of 2403 mg/day over a 14-day period as follows: Table 1. Dosage Titration for ESBRIET in Patients with IPF Treatment days Dosage Days 1 through 7 267 mg three times daily (801 mg/day) Days 8 through 14 534 mg three times daily (1602 mg/day) Days 15 onward 801 mg three times daily (2403 mg/day) Dosages above 2403 mg/day are not recommended for any patient. Patients should not take 2 doses at the same time to make up for a missed dose. Patients should not take more than 3 doses per day. 2.3 Dosage Modifications due to Adverse Reactions Patients who miss 14 or more days of ESBRIET should re-initiate treatment by undergoing the initial 2-week titration regimen up to the full maintenance dosage [see Dosage and Administration (2.2) ] . For treatment interruption of less than 14 days, the dosage prior to the interruption can be resumed. If patients experience significant adverse reactions (i.e., gastrointestinal, photosensitivity reaction or rash, severe cutaneous adverse reactions (SCAR)), consider temporary dosage reductions or interruptions of ESBRIET to allow for resolution of symptoms. If a SCAR is confirmed, permanently discontinue ESBRIET [see Warnings and Precautions (5.1 , 5.2 , 5.3 , 5.4) ] . Dosage Modification due to Elevated Liver Enzymes Dosage modifications or interruptions may also be necessary when liver enzyme and bilirubin elevations are exhibited. For liver enzyme elevations, modify the dosage as follows: If a patient exhibits >3 but ≤5 × the upper limit of normal (ULN) ALT and/or AST without symptoms or hyperbilirubinemia after starting ESBRIET therapy: Discontinue confounding medications, exclude other causes, and monitor the patient closely. Repeat liver chemistry tests as clinically indicated. The full daily dosage may be maintained, if clinically appropriate, or reduced or interrupted (e.g., until liver chemistry tests are within normal limits) with subsequent re-titration to the full dosage as tolerated. If a patient exhibits >3 but ≤5 × ULN ALT and/or AST accompanied by symptoms or hyperbilirubinemia: Permanently discontinue ESBRIET. Do not rechallenge patient with ESBRIET. If a patient exhibits >5 × ULN ALT and/or AST: Permanently discontinue ESBRIET. Do not rechallenge patient with ESBRIET. 2.4 Dosage Modification due to Drug Interactions Strong CYP1A2 Inhibitors (e.g., fluvoxamine, enoxacin) Reduce ESBRIET to 267 mg three times a day (801 mg/day). Moderate CYP1A2 Inhibitors (e.g., ciprofloxacin) With use of ciprofloxacin at a dosage of 750 mg twice daily, reduce ESBRIET to 534 mg three times a day (1602 mg/day).

Warnings and precautions

Elevated liver enzymes and drug-induced liver injury: ALT, AST, and bilirubin elevations have occurred with ESBRIET including cases of drug-induced liver injury. In the postmarketing setting, non-serious and serious cases of drug-induced liver injury, including severe liver injury with fatal outcomes, have been reported. Monitor ALT, AST, and bilirubin before and during treatment. Temporary dosage reductions or discontinuations may be required. ( 2.1 , 5.1 ) Photosensitivity and rash: Photosensitivity and rash have been noted with ESBRIET. Avoid exposure to sunlight and sunlamps. Wear sunscreen and protective clothing daily. Temporary dosage reductions or discontinuations may be required. ( 5.2 ) Severe Cutaneous Adverse Reactions (SCAR): Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reactions with eosinophilia and systemic symptoms (DRESS) have been reported in association with the use of ESBRIET in the postmarketing setting. Interrupt ESBRIET in case of signs or symptoms of SCAR. Permanently discontinue ESBRIET if a SCAR is confirmed. ( 5.3 ) Gastrointestinal disorders: Nausea, vomiting, diarrhea, dyspepsia, gastro-esophageal reflux disease, and abdominal pain have occurred with ESBRIET. Temporary dosage reductions or discontinuations may be required. ( 5.4 ) 5.1 Elevated Liver Enzymes and Drug-Induced Liver Injury Cases of drug-induced liver injury (DILI) have been observed with ESBRIET. In the postmarketing period, non-serious and serious cases of DILI, including severe liver injury with fatal outcome, have been reported. Patients treated with Esbriet 2403 mg/day in three Phase 3 trials had a higher incidence of elevations in ALT or AST ≥3× ULN than placebo patients (3.7% vs 0.8%, respectively). Elevations ≥10×ULN in ALT or AST occurred in 0.3% of patients in the Esbriet 2403 mg/day group and in 0.2% of patients in the placebo group. Increases in ALT and AST ≥3× ULN were reversible with dose modification or treatment discontinuation. Conduct liver function tests (ALT, AST, and bilirubin) prior to the initiation of therapy with ESBRIET, monthly for the first 6 months, every 3 months thereafter, and as clinically indicated. Measure liver function tests promptly in patients who report symptoms that may indicate liver injury, including fatigue, anorexia, right upper abdominal discomfort, dark urine, or jaundice. Dosage modification or interruption may be necessary for liver enzyme elevations [see Dosage and Administration (2.1 , 2.3) ] . 5.2 Photosensitivity Reaction or Rash Patients treated with ESBRIET 2403 mg/day in the three Phase 3 studies had a higher incidence of photosensitivity reactions (9%) compared with patients treated with placebo (1%). The majority of the photosensitivity reactions occurred during the initial 6 months. Instruct patients to avoid or minimize exposure to sunlight (including sunlamps), to use a sunblock (SPF 50 or higher), and to wear clothing that protects against sun exposure. Additionally, instruct patients to avoid concomitant medications known to cause photosensitivity. Dosage reduction or discontinuation may be necessary in some cases of photosensitivity reaction or rash [see Dosage and Administration (2.3) ] . 5.3 Severe Cutaneous Adverse Reactions Severe cutaneous adverse reactions (SCAR), including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported in association with the use of ESBRIET in the postmarketing setting. If signs or symptoms of SCAR occur, interrupt ESBRIET treatment until the etiology of the reaction has been determined. Consultation with a dermatologist is recommended. If a SCAR is confirmed, permanently discontinue ESBRIET. 5.4 Gastrointestinal Disorders In the clinical studies, gastrointestinal events of nausea, diarrhea, dyspepsia, vomiting, gastro-esophageal reflux disease, and abdominal pain were more frequently reported by patients in the ESBRIET treatment groups than in those taking placebo. Dosage reduction or interruption for gastrointestinal events was required in 18.5% of patients in the 2403 mg/day group, as compared to 5.8% of patients in the placebo group; 2.2% of patients in the ESBRIET 2403 mg/day group discontinued treatment due to a gastrointestinal event, as compared to 1.0% in the placebo group. The most common (>2%) gastrointestinal events that led to dosage reduction or interruption were nausea, diarrhea, vomiting, and dyspepsia. The incidence of gastrointestinal events was highest early in the course of treatment (with highest incidence occurring during the initial 3 months) and decreased over time. Dosage modifications may be necessary in some cases of gastrointestinal adverse reactions [see Dosage and Administration (2.3) ] .

Side effects

The following adverse reactions are discussed in greater detail in other sections of the labeling: Liver Enzyme Elevations and Drug-Induced Liver Injury [see Warnings and Precautions (5.1) ] Photosensitivity Reaction or Rash [see Warnings and Precautions (5.2) ] Severe Cutaneous Adverse Reactions [see Warnings and Precautions (5.3) ] Gastrointestinal Disorders [see Warnings and Precautions (5.4) ] The most common adverse reactions (≥10%) are nausea, rash, abdominal pain, upper respiratory tract infection, diarrhea, fatigue, headache, decreased appetite, dyspepsia, dizziness, vomiting, gastro-esophageal reflux disease, sinusitis, insomnia, weight decreased, and arthralgia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Genentech at 1-888-835-2555 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 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 practice. The safety of pirfenidone has been evaluated in more than 1400 subjects with over 170 subjects exposed to pirfenidone for more than 5 years in clinical trials. ESBRIET was studied in 3 randomized, double-blind, placebo-controlled trials (Studies 1, 2, and 3) in which a total of 623 patients received 2403 mg/day of ESBRIET and 624 patients received placebo. Subjects ages ranged from 40 to 80 years (mean age of 67 years). Most patients were male (74%) and Caucasian (95%). The mean duration of exposure to ESBRIET was 62 weeks (range: 2 to 118 weeks) in these 3 trials. At the recommended dosage of 2403 mg/day, 14.6% of patients on ESBRIET compared to 9.6% on placebo permanently discontinued treatment because of an adverse event. The most common (>1%) adverse reactions leading to discontinuation were rash and nausea. The most common (>3%) adverse reactions leading to dosage reduction or interruption were rash, nausea, diarrhea, and photosensitivity reaction. The most common adverse reactions with an incidence of ≥10% and more frequent in the ESBRIET than placebo treatment group are listed in Table 2 . Table 2. Adverse Reactions Occurring in ≥10% of ESBRIET-Treated Patients and More Commonly Than Placebo in Studies 1, 2, and 3 Adverse Reaction % of Patients (0 to 118 Weeks) ESBRIET 2403 mg/day (N = 623) Placebo (N = 624) Nausea 36% 16% Rash 30% 10% Abdominal Pain Includes abdominal pain, upper abdominal pain, abdominal distension, and stomach discomfort. 24% 15% Upper Respiratory Tract Infection 27% 25% Diarrhea 26% 20% Fatigue 26% 19% Headache 22% 19% Decreased Appetite 21% 8% Dyspepsia 19% 7% Dizziness 18% 11% Vomiting 13% 6% Gastro-esophageal Reflux Disease 11% 7% Sinusitis 11% 10% Insomnia 10% 7% Weight Decreased 10% 5% Arthralgia 10% 7% Adverse reactions occurring in ≥5 to <10% of ESBRIET-treated patients and more commonly than placebo are photosensitivity reaction (9% vs. 1%), pruritus (8% vs. 5%), asthenia (6% vs. 4%), dysgeusia (6% vs. 2%), and non-cardiac chest pain (5% vs. 4%). 6.2 Postmarketing Experience In addition to adverse reactions identified from clinical trials the following adverse reactions have been identified during post-approval use of ESBRIET. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency. Blood and Lymphatic System Disorders: Agranulocytosis Hepatobiliary Disorders: Drug-induced liver injury Immune System Disorders: Angioedema Skin and Subcutaneous Tissue Disorders: Severe Cutaneous Adverse Reactions (SCAR)

Drug interactions

Moderate (e.g., ciprofloxacin) and strong inhibitors of CYP1A2 (e.g., fluvoxamine) increase systemic exposure of ESBRIET and may alter the adverse reaction profile of ESBRIET. Discontinue fluvoxamine prior to administration of ESBRIET or reduce to 267 mg three times a day . Consider dosage reduction with use of ciprofloxacin. ( 7.1 ) 7.1 CYP1A2 Inhibitors Pirfenidone is metabolized primarily (70 to 80%) via CYP1A2 with minor contributions from other CYP isoenzymes including CYP2C9, 2C19, 2D6 and 2E1. Strong CYP1A2 Inhibitors The concomitant administration of ESBRIET and fluvoxamine or other strong CYP1A2 inhibitors (e.g., enoxacin) is not recommended because it significantly increases exposure to ESBRIET [see Clinical Pharmacology (12.3) ]. Use of fluvoxamine or other strong CYP1A2 inhibitors should be discontinued prior to administration of ESBRIET and avoided during ESBRIET treatment. In the event that fluvoxamine or other strong CYP1A2 inhibitors are the only drug of choice, dosage reductions are recommended. Monitor for adverse reactions and consider discontinuation of ESBRIET as needed [ see Dosage and Administration (2.4) ] . Moderate CYP1A2 Inhibitors Concomitant administration of ESBRIET and ciprofloxacin (a moderate inhibitor of CYP1A2) moderately increases exposure to ESBRIET [see Clinical Pharmacology (12.3) ] . If ciprofloxacin at the dosage of 750 mg twice daily cannot be avoided, dosage reductions are recommended [see Dosage and Administration (2.4) ]. Monitor patients closely when ciprofloxacin is used at a dosage of 250 mg or 500 mg once daily. Concomitant CYP1A2 and other CYP Inhibitors Agents or combinations of agents that are moderate or strong inhibitors of both CYP1A2 and one or more other CYP isoenzymes involved in the metabolism of ESBRIET (i.e., CYP2C9, 2C19, 2D6, and 2E1) should be discontinued prior to and avoided during ESBRIET treatment. 7.2 CYP1A2 Inducers The concomitant use of ESBRIET and a CYP1A2 inducer may decrease the exposure of ESBRIET and this may lead to loss of efficacy. Therefore, discontinue use of strong CYP1A2 inducers prior to ESBRIET treatment and avoid the concomitant use of ESBRIET and a strong CYP1A2 inducer [see Clinical Pharmacology (12.3) ] .

Use in specific populations

Hepatic Impairment: Monitor for adverse reactions and consider dosage modification or discontinuation of ESBRIET as needed. ESBRIET is not recommended for use in patients with severe hepatic impairment. ( 8.6 , 12.3 ) Renal Impairment: Monitor for adverse reactions and consider dosage modification or discontinuation of ESBRIET as needed. ESBRIET is not recommended for use in patients with end stage renal disease on dialysis. ( 8.7 , 12.3 ) Smokers: Decreased exposure has been noted in smokers which may alter the efficacy profile of ESBRIET. ( 8.8 ) 8.1 Pregnancy Risk Summary The data with ESBRIET use in pregnant women are insufficient to inform on drug associated risks for major birth defects and miscarriage. In animal reproduction studies, pirfenidone was not teratogenic in rats and rabbits at oral doses up to 3 and 2 times, respectively, the maximum recommended daily dose (MRDD) in adults [see Data ] . 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 Animal reproductive studies were conducted in rats and rabbits. In a combined fertility and embryofetal development study, female rats received pirfenidone at oral doses of 0, 50, 150, 450, and 1000 mg/kg/day from 2 weeks prior to mating, during the mating phase, and throughout the periods of early embryonic development from gestation days (GD) 0 to 5 and organogenesis from GD 6 to 17. In an embryofetal development study, pregnant rabbits received pirfenidone at oral doses of 0, 30, 100, and 300 mg/kg/day throughout the period of organogenesis from GD 6 to 18. In these studies, pirfenidone at doses up to 3 and 2 times, respectively, the maximum recommended daily dose (MRDD) in adults (on mg/m 2 basis at maternal oral doses up to 1000 mg/kg/day in rats and 300 mg/kg/day in rabbits, respectively) revealed no evidence of impaired fertility or harm to the fetus due to pirfenidone. In the presence of maternal toxicity, acyclic/irregular cycles (e.g., prolonged estrous cycle) were seen in rats at doses approximately equal to and higher than the MRDD in adults (on a mg/m 2 basis at maternal doses of 450 mg/kg/day and higher). In a pre- and post-natal development study, female rats received pirfenidone at oral doses of 0, 100, 300, and 1000 mg/kg/day from GD 7 to lactation day 20. Prolongation of the gestation period, decreased numbers of live newborn, and reduced pup viability and body weights were seen in rats at an oral dosage approximately 3 times the MRDD in adults (on a mg/m 2 basis at a maternal oral dose of 1000 mg/kg/day). 8.2 Lactation Risk Summary No information is available on the presence of pirfenidone in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. The lack of clinical data during lactation precludes clear determination of the risk of ESBRIET to an infant during lactation; therefore, the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for ESBRIET and the potential adverse effects on the breastfed child from ESBRIET or from the underlying maternal condition. Data Animal Data: A study with radio-labeled pirfenidone in rats has shown that pirfenidone or its metabolites are excreted in milk. There are no data on the presence of pirfenidone or its metabolites in human milk, the effects of pirfenidone on the breastfed child, or its effects on milk production. 8.4 Pediatric Use Safety and effectiveness of ESBRIET in pediatric patients have not been established. 8.5 Geriatric Use Of the total number of subjects in the clinical studies receiving ESBRIET, 714 (67%) were 65 years old and over, while 231 (22%) were 75 years old and over. No overall differences in safety or effectiveness were observed between older and younger patients. No dosage adjustment is required based upon age. 8.6 Hepatic Impairment ESBRIET should be used with caution in patients with mild (Child Pugh Class A) to moderate (Child Pugh Class B) hepatic impairment. Monitor for adverse reactions and consider dosage modification or discontinuation of ESBRIET as needed [ see Dosage and Administration (2.3) ] . The safety, efficacy, and pharmacokinetics of ESBRIET have not been studied in patients with severe hepatic impairment. ESBRIET is not recommended for use in patients with severe (Child Pugh Class C) hepatic impairment [see Clinical Pharmacology (12.3) ] . 8.7 Renal Impairment ESBRIET should be used with caution in patients with mild (CL cr 50–80 mL/min), moderate (CL cr 30–50 mL/min), or severe (CL cr less than 30 mL/min) renal impairment [see Clinical Pharmacology (12.3) ]. Monitor for adverse reactions and consider dosage modification or discontinuation of ESBRIET as needed [ see Dosage and Administration (2.3) ] . The safety, efficacy, and pharmacokinetics of ESBRIET have not been studied in patients with end-stage renal disease requiring dialysis. Use of ESBRIET in patients with end-stage renal diseases requiring dialysis is not recommended. 8.8 Smokers Smoking causes decreased exposure to ESBRIET [see Clinical Pharmacology (12.3) ], which may alter the efficacy profile of ESBRIET. Instruct patients to stop smoking prior to treatment with ESBRIET and to avoid smoking when using ESBRIET.

Pediatric use

8.4 Pediatric Use Safety and effectiveness of ESBRIET in pediatric patients have not been established.

Geriatric use

8.5 Geriatric Use Of the total number of subjects in the clinical studies receiving ESBRIET, 714 (67%) were 65 years old and over, while 231 (22%) were 75 years old and over. No overall differences in safety or effectiveness were observed between older and younger patients. No dosage adjustment is required based upon age.

Overdosage

There is limited clinical experience with overdosage. Multiple dosages of ESBRIET up to a maximum tolerated dose of 4005 mg per day were administered as five 267 mg capsules three times daily to healthy adult volunteers over a 12-day dose escalation. In the event of a suspected overdosage, appropriate supportive medical care should be provided, including monitoring of vital signs and observation of the clinical status of the patient.
