`
`-----------------WARNINGS AND PRECAUTIONS-----------------
`• Drug-induced hepatitis (e.g., acute hepatitis, cytolytic hepatitis)
`
`
`has been reported with PREZISTA/ritonavir. Monitor liver
`function before and during therapy, especially in patients
`with underlying chronic hepatitis, cirrhosis, or in patients
`who have pre-treatment elevations of transaminases. (5.2, 6)
`• Skin reactions ranging from mild to severe, including Stevens-
`
`
`Johnson Syndrome and toxic epidermal necrolysis, have been
`
`reported. Discontinue treatment if severe reaction develops.
`(5.3, 6)
`• Use with caution in patients with a known sulfonamide allergy.
`
`
`(5.4)
`• Patients may develop new onset diabetes mellitus or
`
`
`hyperglycemia. Initiation or dose adjustments of insulin or
`
`oral hypoglycemic agents may be required. (5.6)
`• Patients may develop redistribution/accumulation of body fat
`
`(5.7) or immune reconstitution syndrome. (5.8)
`• Patients with hemophilia may develop increased bleeding
`
`events. (5.9)
`• PREZISTA/ritonavir should not be used in pediatric patients
`
`
`below 3 years of age. (5.11)
`
`
`-----------------------ADVERSE REACTIONS-------------------------
`• The most common clinical adverse drug reactions to
`
`PREZISTA/ritonavir (incidence ≥ 5%) of at least moderate
`
`intensity (≥ Grade 2) were diarrhea, nausea, rash, headache,
`
`
`abdominal pain and vomiting. (6)
`

`
`
`
`INDICATIONS AND USAGE
`1
`
`1.1 Adult Patients
`
`PREZISTA®, co-administered with ritonavir (PREZISTA/ritonavir), and with other antiretroviral agents, is indicated
`
`for the treatment of human immunodeficiency virus (HIV-1) infection.
`
`This indication is based on analyses of plasma HIV RNA levels and CD4+ cell counts from 2 controlled Phase 3
`
`
`
`
`trials of 48 weeks duration in antiretroviral treatment-naïve and treatment-experienced patients and 2 controlled
`
`
`Phase 2 trials of 96 weeks duration in clinically advanced, treatment-experienced adult patients.
`
`
`Pediatric Patients
`1.2
`PREZISTA, co-administered with ritonavir (PREZISTA/ritonavir), and with other antiretroviral agents, is indicated
`
`
`
`
`for the treatment of HIV infection in pediatric patients 6 years of age and older [see Use in Specific Populations
`
`
`(8.4)].
`
`
`This indication is based on 24-week analyses of plasma HIV RNA levels and CD4+ cell counts from an open-label
`
`Phase 2 trial in antiretroviral treatment-experienced pediatric patients 6 to < 18 years of age.
`
`
`
`In treatment-experienced adult and pediatric patients, the following points should be considered when initiating
`
`
`
`therapy with PREZISTA/ritonavir:
`
`
`• Treatment history and, when available, genotypic or phenotypic testing should guide the use of
`
`
`
`
`PREZISTA/ritonavir [see Clinical Pharmacology (12.4)].
`
`• The use of other active agents with PREZISTA/ritonavir is associated with a greater likelihood of treatment
`
`response [see Clinical Pharmacology (12.4) and Clinical Studies (14.3)].
`
`
`
`2 DOSAGE AND ADMINISTRATION
`
`
`2.1 Adult Patients
`
`PREZISTA must be co-administered with ritonavir to exert its therapeutic effect. Failure to correctly co-administer
`
`
`PREZISTA with ritonavir will result in plasma levels of darunavir that will be insufficient to achieve the desired
`
`antiviral effect and will alter some drug interactions.
`
`Treatment-Naïve Adult Patients
`The recommended oral dose of PREZISTA tablets is 800 mg (two 400 mg tablets) taken with ritonavir 100 mg once
`
`
`
`
`
`daily and with food.
`
`
`Treatment-Experienced Adult Patients
`The recommended oral dose of PREZISTA tablets is 600 mg (one 600 mg tablet or two 300 mg tablets) taken with
`
`
`
`
`ritonavir 100 mg twice daily and with food. Once daily administration of PREZISTA is not recommended in
`
`treatment-experienced adult patients.
`
`
`Pediatric Patients (age 6 to < 18 years)
`2.2
`
`Do not use once daily dosing in pediatric patients.
`
`
`
`Healthcare professionals should pay special attention to accurate dose selection of PREZISTA, transcription of the
`
`medication order, dispensing information and dosing instruction to minimize risk for medication errors, overdose,
`
`and underdose.
`
`Prescribers should select the appropriate dose of PREZISTA/ritonavir for each individual child based on body
`
`weight (kg) and should not exceed the recommended dose for treatment-experienced adults.
`
`
`
`
`
`
`
`
`
`
`
`4
`
`
`
`
`Before prescribing PREZISTA, children should be assessed for the ability to swallow tablets. If a child is unable to
`
`
`
`reliably swallow a tablet, the use of PREZISTA tablets may not be appropriate.
`
`
`
`The recommended dose of PREZISTA/ritonavir for pediatric patients (6 to < 18 years of age and weighing at least
`
`
`
`44 lbs (20 kg)) is based on body weight (see Table 1) and should not exceed the recommended treatment-
`
`
`experienced adult dose (PREZISTA/ritonavir 600/100 mg b.i.d.). PREZISTA tablets should be taken with ritonavir
`
`
`twice daily and with food.

`
`
`
`The safety and efficacy of PREZISTA/ritonavir in pediatric patients 3 to < 6 years of age have not been established.
`
`Do not use PREZISTA/ritonavir in pediatric patients below 3 years of age [see Warnings and Precautions (5.11)
`
`
`
`
`and Nonclinical Toxicology (13.2)].
`
`
`
`Patients with Hepatic Impairment
`2.3
`No dose adjustment is required in patients with mild or moderate hepatic impairment. No data are available
`
`regarding the use of PREZISTA/ritonavir when co-administered to subjects with severe hepatic impairment;
`
`
`
`therefore, PREZISTA/ritonavir is not recommended for use in patients with severe hepatic impairment [see Use in
`Specific Populations (8.6) and Clinical Pharmacology (12.3)].

`4 CONTRAINDICATIONS
`
`Co-administration of PREZISTA/ritonavir is contraindicated with drugs that are highly dependent on CYP3A for
`
`
`
`clearance and for which elevated plasma concentrations are associated with serious and/or life-threatening events
`
`
`(narrow therapeutic index). These drugs and other contraindicated drugs (which may lead to reduced efficacy of
`
`darunavir) are listed in Table 2 [also see Drug Interactions (7.3), Table 7].

`Potential for serious and/or life-threatening
`
`reactions such as cardiac arrhythmias.
`Orally administered Midazolam, Triazolam Triazolam and orally administered
`
`midazolam are extensively metabolized by
`CYP3A. Co-administration of triazolam or
`
`
`orally administered midazolam with
`PREZISTA/ritonavir may cause large
`increases in the concentrations of these
`benzodiazepines. Potential for serious
`and/or life-threatening events such as
`prolonged or increased sedation or
`
`
`respiratory depression.
`Patients taking PREZISTA/ritonavir should
`
`not use products containing St. John’s wort
`
`because co-administration may result in
`reduced plasma concentrations of
`darunavir. This may result in loss of
`
`therapeutic effect and development of
`resistance.

`
`Rifampin is a potent inducer of CYP450
`
`metabolism. PREZISTA/ritonavir should
`not be used in combination with rifampin,
`
`
`as this may cause significant decreases in
`
`darunavir plasma concentrations. This may
`
`result in loss of therapeutic effect to
`
`PREZISTA.
`A safe and effective dose for the treatment
`
`of pulmonary arterial hypertension has not
`
`been established with PREZISTA/ritonavir.
`There is an increased potential for
`
`
`sildenafil-associated adverse events (which
`
`include visual disturbances, hypotension,
`prolonged erection, and syncope).
`
`
`Due to the need for co-administration of PREZISTA with ritonavir, please refer to ritonavir prescribing information
`for a description of ritonavir contraindications.
`
`
`5 WARNINGS AND PRECAUTIONS
`
`5.1 General
`
`
`PREZISTA must be co-administered with ritonavir and food to achieve the desired antiviral effect. Failure to
`administer PREZISTA with ritonavir and food may result in a loss of efficacy of darunavir.
`
`
`
`Please refer to ritonavir prescribing information for additional information on precautionary measures.
`
`
`
`5.2 Hepatotoxicity
`Drug-induced hepatitis (e.g., acute hepatitis, cytolytic hepatitis) has been reported with PREZISTA/ritonavir. During
`the clinical development program (N=3063), hepatitis was reported in 0.5% of patients receiving combination
`therapy with PREZISTA/ritonavir. Patients with pre-existing liver dysfunction, including chronic active hepatitis B
`
`or C, have an increased risk for liver function abnormalities including severe hepatic adverse events.
`
`
`Post-marketing cases of liver injury, including some fatalities, have been reported. These have generally occurred in
`
`
`patients with advanced HIV-1 disease taking multiple concomitant medications, having co-morbidities including
`
`
`hepatitis B or C co-infection, and/or developing immune reconstitution syndrome. A causal relationship with
`
`PREZISTA/ritonavir therapy has not been established.
`
`
`
`Appropriate laboratory testing should be conducted prior to initiating therapy with PREZISTA/ritonavir and patients
`
`
`
`
`should be monitored during treatment. Increased AST/ALT monitoring should be considered in patients with
`
`
`
`underlying chronic hepatitis, cirrhosis, or in patients who have pre-treatment elevations of transaminases, especially
`during the first several months of PREZISTA/ritonavir treatment.
`
`
`
`Evidence of new or worsening liver dysfunction (including clinically significant elevation of liver enzymes and/or
`
`symptoms such as fatigue, anorexia, nausea, jaundice, dark urine, liver tenderness, hepatomegaly) in patients on
`
`
`
`PREZISTA/ritonavir should prompt consideration of interruption or discontinuation of treatment.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`7
`
`
`
`
`
`Severe Skin Reactions
`5.3
`During the clinical development program (n=3063), severe skin reactions, accompanied by fever and/or elevations
`
`of transaminases in some cases, have been reported in 0.4% of subjects. Stevens-Johnson Syndrome was rarely
`
`
`(<0.1%) reported during the clinical development program. During post-marketing experience toxic epidermal
`
`necrolysis has been reported. Discontinue PREZISTA/rtv immediately if signs or symptoms of severe skin reactions
`
`
`
`
`
`develop. These can include but are not limited to severe rash or rash accompanied with fever, general malaise,
`
`fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, hepatitis and/or eosinophilia.
`
`Rash (all grades, regardless of causality) occurred in 10.3% of subjects treated with PREZISTA/rtv [also see
`
`
`Adverse Reactions (6)]. Rash was mostly mild-to-moderate, often occurring within the first four weeks of treatment
`
`
`
`
`and resolving with continued dosing. The discontinuation rate due to rash in subjects using PREZISTA/rtv was
`
`
`
`0.5%.
`
`
`Sulfa Allergy
`5.4
`Darunavir contains a sulfonamide moiety. PREZISTA should be used with caution in patients with a known
`
`
`sulfonamide allergy. In clinical studies with PREZISTA/ritonavir, the incidence and severity of rash was similar in
`
`
`subjects with or without a history of sulfonamide allergy.
`
`
`
`
`5.5 Drug Interactions
`See Table 2 for a listing of drugs that are contraindicated for use with PREZISTA/ritonavir due to potentially life-
`
`
`threatening adverse events, significant drug-drug interactions, or loss of therapeutic effect to PREZISTA [see
`
`Contraindications (4)]. Please refer to Table 7 for established and other potentially significant drug-drug interactions
`
`[see Drug Interactions (7.3)].
`
`
`
`
`5.6 Diabetes Mellitus / Hyperglycemia
`New onset diabetes mellitus, exacerbation of pre-existing diabetes mellitus, and hyperglycemia have been reported
`during postmarketing surveillance in HIV-infected patients receiving protease inhibitor (PI) therapy. Some patients
`required either initiation or dose adjustments of insulin or oral hypoglycemic agents for treatment of these events. In
`
`
`
`some cases, diabetic ketoacidosis has occurred. In those patients who discontinued PI therapy, hyperglycemia
`
`persisted in some cases. Because these events have been reported voluntarily during clinical practice, estimates of
`frequency cannot be made and causal relationships between PI therapy and these events have not been established.
`
`
`
`
`
`
`Fat Redistribution
`5.7
`Redistribution/accumulation of body fat, including central obesity, dorsocervical fat enlargement (buffalo hump),
`peripheral wasting, facial wasting, breast enlargement, and “cushingoid appearance” have been observed in patients
`
`receiving antiretroviral therapy. The mechanism and long-term consequences of these events are currently unknown.
`
`A causal relationship has not been established.
`
`
`
`
`Immune Reconstitution Syndrome
`5.8
`During the initial phase of treatment, patients responding to antiretroviral therapy may develop an inflammatory
`
`response to indolent or residual opportunistic infections (such as Mycobacterium avium complex, cytomegalovirus,
`
`Pneumocystis jirovecii pneumonia, and tuberculosis), which may necessitate further evaluation and treatment.
`
`5.9
`Hemophilia
`
`There have been reports of increased bleeding, including spontaneous skin hematomas and hemarthrosis in patients
`
`
`
`with hemophilia type A and B treated with PIs. In some patients, additional factor VIII was given. In more than half
`
`
`
`
`of the reported cases, treatment with PIs was continued or reintroduced if treatment had been discontinued. A causal
`
`relationship between PI therapy and these episodes has not been established.
`
`Resistance/Cross-Resistance
`
`5.10
`Because the potential for HIV cross-resistance among PIs has not been fully explored in PREZISTA/ritonavir
`treated patients, the effect therapy with PREZISTA will have on the activity of subsequently administered PIs is
`
`unknown [see Microbiology (12.4)].

`
`Pediatric Patients
`5.11
`Do not administer PREZISTA/ritonavir in pediatric patients below 3 years of age in view of toxicity and mortality
`
`
`
`observed in juvenile rats dosed with darunavir (from 20 mg/kg to 1000 mg/kg) up to days 23 to 26 of age [see Use in
`
`
`
`
`Specific Populations (8.1 and 8.4), Clinical Pharmacology (12.3), and Nonclinical Toxicology (13.2)]. The safety
`and efficacy of PREZISTA/ritonavir in pediatric patients 3 to < 6 years of age have not been established.
`
`
`
`ADVERSE REACTIONS

`The safety assessment is based on all safety data from the Phase 2b studies (Studies TMC114-C213, TMC114-C202,
`
`TMC114-C215, and TMC114-C208) and Phase 3 studies (TMC114-C211, TMC114-C214, TMC114-C209, DUET
`
`1 (TMC125-C206), and DUET-2 (TMC125-C216)) reported with PREZISTA/ritonavir in a total of 3063 subjects.
`
`
`
`
`
`
`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.
`
`Due to the need for co-administration of PREZISTA with ritonavir, please refer to ritonavir prescribing information
`for ritonavir-associated adverse reactions.

`
`6.1 Clinical Trials Experience: Treatment-Naïve Adults
`Study TMC114-C211
`
`The safety assessment is based on all safety data from the Phase 3 trial TMC114-C211 comparing
`
`PREZISTA/ritonavir 800/100 mg once daily versus lopinavir/ritonavir 800/200 mg per day in 689 antiretroviral
`
`
`treatment-naïve HIV-1-infected adult subjects. The total mean exposure for subjects in the PREZISTA/ritonavir
`800/100 mg once daily arm and in the lopinavir/ritonavir 800/200 mg per day arm was 95.0 and 91.4 weeks,
`
`
`respectively.
`
`The majority of the adverse drug reactions (ADRs) reported during treatment with PREZISTA/ritonavir 800/100 mg
`
`
`once daily were mild in severity. The most common clinical ADRs to PREZISTA/ritonavir 800/100 mg once daily
`
`
`(≥ 5%) of at least moderate intensity (≥ Grade 2) were diarrhea, headache, abdominal pain and rash. 2.3% of
`
`
`subjects in the PREZISTA/ritonavir arm discontinued treatment due to ADRs.
`
`ADRs to PREZISTA/ritonavir 800/100 mg once daily of at least moderate intensity (≥ Grade 2) in antiretroviral
`
`
`
`treatment naïve HIV-1-infected adult subjects are presented in Table 3 and subsequent text below the table.
