1.1 Treatment of HIV-1 in Treatment-Naïve Patients

EDURANT and EDURANT PED, in combination with other antiretroviral agents, is indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in antiretroviral treatment-naïve patients 2 years of age and older and weighing at least 14 kg with plasma HIV-1 RNA less than or equal to 100,000 copies/mL at the start of therapy.

1.2 Treatment of HIV-1 in Combination with Cabotegravir

EDURANT is indicated in combination with VOCABRIA (cabotegravir) for short-term treatment of HIV-1 infection in adults and adolescents 12 years and older and weighing at least 35 kg who are virologically suppressed (HIV-1 RNA less than 50 copies/mL) on a stable antiretroviral regimen with no history of treatment failure and with no known or suspected resistance to either cabotegravir or rilpivirine, for use as [see Dosage and Administration (2.6)] :

• oral lead-in to assess the tolerability of rilpivirine prior to administration of rilpivirine extended-release injectable suspension, a component of CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension).
• oral therapy for patients who will miss planned injection dosing with CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension).

2.1 Overview of Different Dosage Forms

EDURANT is available in two dosage forms:

• EDURANT 25 mg film-coated tablets for adults and pediatric patients weighing at least 25 kg.
• EDURANT PED 2.5 mg tablets for oral suspension should only be given to pediatric patients weighing at least 14 kg to less than 25 kg [see Dosage and Administration (2.3)] .

Do not substitute EDURANT tablets and EDURANT PED tablets for oral suspension on a milligram-per-milligram basis due to differing pharmacokinetic profiles. A difference in bioavailability between 1 × 25 mg film-coated tablet and 10 × 2.5 mg tablets for oral suspension was observed; therefore, they are NOT substitutable [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.3)].

Take EDURANT and EDURANT PED once daily with a meal in combination with other antiretrovirals [see Clinical Pharmacology (12.3)].

2.2 Recommended Dosage in Treatment-Naïve Adult Patients

The recommended dosage of EDURANT in adult patients is one 25 mg tablet taken orally once daily with a meal [see Use in Specific Populations (8.1) and Clinical Pharmacology (12.3)] .

2.3 Recommended Dosage in Treatment-Naïve Pediatric Patients 2 Years of Age and Older and Weighing at least 14 kg

The recommended dosage of EDURANT and EDURANT PED in pediatric patients 2 years of age and older and weighing at least 14 kg is based on body weight (see Table 1). Both EDURANT and EDURANT PED should be taken orally once daily with a meal [see Use in Specific Populations (8.4) and Clinical Pharmacology (12.3)] .

2.4 Preparation and Administration Instructions for EDURANT PED Only

Advise patients or caregivers of patients taking EDURANT PED to refer to the Instructions for Use to properly prepare and take the medication.

EDURANT PED must be dispersed in drinking water and taken immediately with a meal. If not taken immediately, then the oral suspension should be discarded, and a new dose of medicine should be prepared. The patient should not chew or swallow EDURANT PED whole. The following instructions should be followed:

• Place the tablets for oral suspension in a cup, add 5 mL (1 teaspoon) of drinking water at room temperature. Do not crush the tablets.
• Swirl the cup carefully for 1–2 minutes to disperse the tablets. The oral suspension will start to look cloudy.
• Take all the prepared oral suspension immediately or to aid in administration, the oral suspension can be further diluted with 5 mL (1 teaspoon) of drinking water, milk, orange juice or applesauce. Swirl and take all the medicine immediately. A spoon can be used if needed.
• Make sure the entire dose is taken and no medicine is left in the cup. If required, add another 5 mL (1 teaspoon) of drinking water (or alternative beverage or soft food), swirl and drink immediately.

2.5 Recommended Dosage During Pregnancy

For pregnant patients who are already on a stable EDURANT regimen prior to pregnancy and who are virologically suppressed (HIV-1 RNA less than 50 copies per mL) the recommended dosage in adults and pediatric patients weighing at least 25 kg is one 25 mg tablet once daily taken orally with a meal. Refer to Table 1 for dosing recommendations for pediatric patients [see Dosage and Administration (2.2, 2.3)]. Lower exposures of rilpivirine were observed during pregnancy, therefore viral load should be monitored closely [see Use in Specific Populations (8.1) and Clinical Pharmacology (12.3)] .

2.6 Recommended Dosage in Combination with Cabotegravir in Adults and Adolescents 12 Years of Age and Older and Weighing at least 35 kg

Consult the prescribing information for CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension) before initiating EDURANT to ensure therapy with CABENUVA is appropriate.

2.7 Recommended Dosage with Rifabutin Coadministration

If EDURANT is coadministered with rifabutin, the EDURANT dose should be increased to 50 mg (two 25 mg tablets) once daily, taken with a meal. When rifabutin coadministration is stopped, the EDURANT dose should be decreased to 25 mg once daily, taken with a meal [see Drug Interactions (7) and Clinical Pharmacology (12.3)].

Note that use of CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension) with rifabutin is contraindicated. Refer to CABENUVA labeling for additional detail.

EDURANT 25 mg Film-Coated Tablets

25 mg white to off-white, film-coated, round, biconvex, tablet of 6.4 mm, debossed with "TMC" on one side and "25" on the other side. Each tablet contains 27.5 mg of rilpivirine hydrochloride, which is equivalent to 25 mg of rilpivirine.

EDURANT PED 2.5 mg Tablets for Oral Suspension

2.5 mg white to almost white, round 6.5 mm tablet, debossed with "TMC" on one side and "PED" on the other side. Each tablet for oral suspension contains 2.75 mg of rilpivirine hydrochloride equivalent to 2.5 mg rilpivirine.

5.1 Skin and Hypersensitivity Reactions

Severe skin and hypersensitivity reactions have been reported during the postmarketing experience, including cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), with rilpivirine-containing regimens. While some skin reactions were accompanied by constitutional symptoms such as fever, other skin reactions were associated with organ dysfunctions, including elevations in hepatic serum biochemistries. During the Phase 3 clinical trials, treatment-related rashes with at least Grade 2 severity were reported in 3% of subjects receiving EDURANT. No Grade 4 rash was reported. Overall, most rashes were Grade 1 or 2 and occurred in the first four to six weeks of therapy [see Adverse Reactions (6.1 and 6.2)] . Discontinue EDURANT or EDURANT PED immediately if signs or symptoms of severe skin or hypersensitivity reactions develop, including but not limited to, severe rash or rash accompanied by fever, blisters, mucosal involvement, conjunctivitis, facial edema, angioedema, hepatitis or eosinophilia. Clinical status including laboratory parameters should be monitored and appropriate therapy should be initiated.

5.2 Hepatotoxicity

Hepatic adverse events have been reported in patients receiving a rilpivirine-containing regimen. Patients with underlying hepatitis B or C virus infection, or marked elevations in transaminases prior to treatment may be at increased risk for worsening or development of transaminase elevations with use of EDURANT or EDURANT PED. A few cases of hepatic toxicity have been reported in adult patients receiving a rilpivirine-containing regimen who had no pre-existing hepatic disease or other identifiable risk factors. Appropriate laboratory testing prior to initiating therapy and monitoring for hepatotoxicity during therapy with EDURANT or EDURANT PED is recommended in patients with underlying hepatic disease such as hepatitis B or C virus infection, or in patients with marked elevations in transaminases prior to treatment initiation. Liver enzyme monitoring should also be considered for patients without pre-existing hepatic dysfunction or other risk factors.

5.3 Depressive Disorders

The adverse reaction depressive disorders (depressed mood, depression, dysphoria, major depression, mood altered, negative thoughts, suicide attempt, suicidal ideation) has been reported with EDURANT. Patients with severe depressive symptoms should seek immediate medical evaluation to assess the possibility that the symptoms are related to EDURANT or EDURANT PED, and if so, to determine whether the risks of continued therapy outweigh the benefits.

During the Phase 3 trials in adults (N=1368) through 96 weeks, the incidence of depressive disorders (regardless of causality, severity) reported among EDURANT (n=686) or efavirenz (n=682) was 9% and 8%, respectively. Most events were mild or moderate in severity. The incidence of Grade 3 and 4 depressive disorders (regardless of causality) was 1% for both EDURANT and efavirenz. The incidence of discontinuation due to depressive disorders among EDURANT or efavirenz was 1% in each arm. Suicidal ideation was reported in 4 subjects in each arm while suicide attempt was reported in 2 subjects in the EDURANT arm.

During the Phase 2 trial in pediatric subjects 12 to less than 18 years of age (N=36) receiving EDURANT through 48 weeks, the incidence of depressive disorders (regardless of causality, severity) was 19.4% (7/36). Most events were mild or moderate in severity. The incidence of Grade 3 and 4 depressive disorders (regardless of causality) was 5.6% (2/36). None of the subjects discontinued due to depressive disorders. Suicidal ideation and suicide attempt were reported in 1 subject.

5.4 Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions

The concomitant use of EDURANT or EDURANT PED and other drugs may result in potentially significant drug interactions, some of which may lead to [see Dosage and Administration (2.7), Contraindications (4), and Drug Interactions (7)] :

• Loss of therapeutic effect of EDURANT or EDURANT PED and possible development of resistance.

In healthy subjects, 75 mg once daily and 300 mg once daily (3 times and 12 times the dose in EDURANT) have been shown to prolong the QTc interval of the electrocardiogram. Consider alternatives to EDURANT or EDURANT PED when coadministered with a drug that is known to have a risk of torsade de pointes [see Drug Interactions (7) and Clinical Pharmacology (12.2)] .

See Table 6for steps to prevent or manage these possible and known significant drug interactions, including dosing recommendations. Consider the potential for drug interactions prior to and during EDURANT or EDURANT PED therapy and review concomitant medications during therapy.

5.5 Immune Reconstitution Syndrome

Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including EDURANT. During the initial phase of combination antiretroviral treatment, patients whose immune system responds may develop an inflammatory response to indolent or residual opportunistic infections (such as Mycobacterium aviuminfection, cytomegalovirus, Pneumocystis jiroveciipneumonia or tuberculosis), which may necessitate further evaluation and treatment.

Autoimmune disorders (such as Graves' disease, polymyositis, Guillain-Barré syndrome, and autoimmune hepatitis) have also been reported to occur in the setting of immune reconstitution; however, the time to onset is more variable, and can occur many months after initiation of treatment.

5.6 Different Formulations Are Not Substitutable

EDURANT and EDURANT PED have differing pharmacokinetic profiles and are not substitutable on a milligram-per-milligram basis. A difference in bioavailability between 1 × 25 mg film-coated tablet and 10 × 2.5 mg tablets for oral suspension was observed; therefore, they are not substitutable [see Clinical Pharmacology (12.3)]. When a pediatric patient weighs 25 kg or greater, they must switch from EDURANT PED tablets for oral suspension to one 25 mg EDURANT tablet daily [see Dosage and Administration (2.3)]. Incorrect dosing of a given formulation may result in underdosing and loss of therapeutic effect and possible development of resistance or possible clinically significant adverse reactions from greater exposure to rilpivirine.

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.

6.2 Postmarketing Experience

Adverse reactions have been identified during postmarketing experience in patients receiving a rilpivirine containing regimen. Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Renal and Genitourinary Disorders:nephrotic syndrome

Skin and Subcutaneous Tissue Disorders:Severe skin and hypersensitivity reactions including DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms)

QT Prolonging Drugs

There is limited information available on the potential for a pharmacodynamic interaction between rilpivirine and drugs that prolong the QTc interval of the electrocardiogram. In a study of healthy subjects, 75 mg once daily and 300 mg once daily (3 times and 12 times the dose in EDURANT) have been shown to prolong the QTc interval of the electrocardiogram [see Clinical Pharmacology (12.2)] . Consider alternatives to EDURANT when coadministered with a drug with a known risk of torsade de pointes.

8.1 Pregnancy

8.2 Lactation

8.4 Pediatric Use

The safety and effectiveness of EDURANT and EDURANT PED has been established for the treatment of HIV-1 infection in treatment-naïve pediatric patients 2 years of age and older and weighing at least 14 kg. Use of EDURANT or EDURANT PED in this population is supported by three trials: TMC278-C213, TMC278HTX2002 and MOCHA.

8.5 Geriatric Use

Clinical studies of EDURANT did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, caution should be exercised in the administration and monitoring of EDURANT in elderly patients reflecting the greater frequency of decreased renal and hepatic function, and of concomitant disease or other drug therapy.

8.6 Renal Impairment

No dose adjustment of EDURANT or EDURANT PED is required in patients with mild or moderate renal impairment. However, in patients with severe renal impairment or end-stage renal disease, EDURANT or EDURANT PED should be used with caution and with increased monitoring for adverse effects, as rilpivirine concentrations may be increased due to alteration of drug absorption, distribution, and metabolism secondary to renal dysfunction. As rilpivirine is highly bound to plasma proteins, it is unlikely that it will be significantly removed by hemodialysis or peritoneal dialysis [see Clinical Pharmacology (12.3)] .

8.7 Hepatic Impairment

No dosage adjustment of EDURANT or EDURANT PED is required in patients with mild (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment. EDURANT and EDURANT PED have not been studied in patients with severe hepatic impairment (Child-Pugh Class C) [see Clinical Pharmacology (12.3)] .

12.1 Mechanism of Action

Rilpivirine is an antiviral drug [see Microbiology (12.4)] .

12.2 Pharmacodynamics

12.3 Pharmacokinetics

12.4 Microbiology

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

14.1 Treatment-Naïve Adult Subjects

The evidence of efficacy of EDURANT is based on the analyses of 48- and 96-week data from 2 randomized, double-blinded, active controlled, Phase 3 trials TMC278-C209 (ECHO) and TMC278-C215 (THRIVE) in antiretroviral treatment-naïve adults. Antiretroviral treatment-naïve HIV-1 infected subjects enrolled in the Phase 3 trials had a plasma HIV-1 RNA ≥5000 copies/mL and were screened for susceptibility to N(t)RTIs and for absence of specific NNRTI resistance-associated substitutions (RASs). The Phase 3 trials were identical in design, apart from the background regimen (BR). In TMC278-C209, the BR was fixed to the N(t)RTIs, tenofovir disoproxil fumarate plus emtricitabine. In TMC278-C215, the BR consisted of 2 investigator-selected N(t)RTIs: tenofovir disoproxil fumarate plus emtricitabine orzidovudine plus lamivudine orabacavir plus lamivudine. In both trials, randomization was stratified by screening viral load. In TMC278-C215, randomization was also stratified by N(t)RTI BR.

In the pooled analysis for TMC278-C209 and TMC278-C215, demographics and baseline characteristics were balanced between the EDURANT arm and the efavirenz arm. Table 14 displays selected demographic and baseline disease characteristics of the subjects in the EDURANT and efavirenz arms.

Week 96 efficacy outcomes for subjects treated with EDURANT 25 mg once daily from the pooled analysis are shown in Table 15. The incidence of virologic failure was higher in the EDURANT arm than the efavirenz arm at Week 96. Virologic failures and discontinuations due to adverse events mostly occurred in the first 48 weeks of treatment. Regardless of HIV-1 RNA at the start of therapy, more EDURANT treated subjects with CD4+ cell count less than 200 cells/mm 3experienced virologic failure compared to EDURANT treated subjects with CD4+ cell count greater than or equal to 200 cells/mm 3.

At Week 96, the mean CD4+ cell count increase from baseline was 228 cells/mm 3for EDURANT-treated subjects and 219 cells/mm 3for efavirenz-treated subjects in the pooled analysis of the TMC278-C209 and TMC278-C215 trials.

Study TMC278-C204 was a randomized, active-controlled, Phase 2b trial in antiretroviral treatment-naïve HIV-1-infected adult subjects consisting of 2 parts: an initial 96 weeks, partially-blinded dose-finding part [EDURANT doses blinded] followed by a long-term, open-label part. After Week 96, subjects randomized to one of the 3 doses of EDURANT were switched to EDURANT 25 mg once daily. Subjects in the control arm received efavirenz 600 mg once daily in addition to a BR in both parts of the study. The BR consisted of 2 investigator-selected N(t)RTIs: zidovudine plus lamivudine ortenofovir disoproxil fumarate plus emtricitabine.

Study TMC278-C204 enrolled 368 HIV-1-infected treatment-naïve adult subjects who had a plasma HIV-1 RNA ≥5000 copies/mL, previously received ≤2 weeks of treatment with an N(t)RTI or protease inhibitor, had no prior use of NNRTIs, and were screened for susceptibility to N(t)RTI and for absence of specific NNRTI RASs.

At 96 weeks, the proportion of subjects with <50 HIV-1 RNA copies/mL receiving EDURANT 25 mg (N=93) compared to subjects receiving efavirenz (N=89) was 76% and 71%, respectively. The mean increase from baseline in CD4+ counts was 146 cells/mm 3in subjects receiving EDURANT 25 mg and 160 cells/mm 3in subjects receiving efavirenz.

At 240 weeks, 60% (56/93) of subjects who originally received 25 mg once daily achieved HIV RNA <50 copies/mL compared to 57% (51/89) of subjects in the control group.

14.2 Virologically-Suppressed Adults Treated in Combination with Cabotegravir

The use of EDURANT in combination with VOCABRIA (cabotegravir) as an oral lead-in and in patients who miss planned injections with CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension) was evaluated in two Phase 3 randomized, multicenter, active-controlled, parallel-arm, open-label, non-inferiority trials (Trial 201584: FLAIR [NCT02938520], Trial 201585: ATLAS [NCT2951052]), and one Phase 3b randomized, multicenter, parallel-group, open-label, non-inferiority trial (Trial 207966: ATLAS-2M [NCT03299049]) in subjects who were virologically suppressed (HIV-1 RNA <50 copies/mL). See full prescribing information for VOCABRIA and CABENUVA for additional information.

14.3 Treatment-Naïve Pediatric Subjects (≥12 to less than 18 Years of Age)

The pharmacokinetics, safety, tolerability and efficacy of EDURANT 25 mg once daily, in combination with an investigator-selected background regimen (BR) containing two NRTIs, was evaluated in trial TMC278-C213 Cohort 1, a single-arm, open-label Phase 2 trial in antiretroviral treatment-naïve HIV-1 infected pediatric subjects 12 to less than 18 years of age and weighing at least 32 kg. Thirty six (36) subjects were enrolled in the trial to complete at least 48 weeks of treatment. The 36 subjects had a median age of 14.5 years (range: 12 to 17 years), and were 56% female, 89% Black and 11% Asian.

In the efficacy analysis, most subjects (75%; 28/36) had baseline HIV RNA <100,000 copies/mL. For these 28 subjects the median baseline plasma HIV-1 RNA was 44,250 (range: 2,060–92,600 copies/mL) and the median baseline CD4+ cell count was 445.5 cells/mm 3(range: 123 to 983 cells/mm 3).

Among the subjects who had baseline HIV RNA ≤100,000, the proportion with HIV-1 RNA <50 copies/mL at Week 48 was 79% (22/28), versus 50% (4/8) in those with >100,000 copies/mL. The proportion of virologic failures among subjects with a baseline viral load ≤100,000 copies/mL was 21% (6/28), versus 38% (3/8) in those with >100,000 copies/mL. At Week 48, the mean increase in CD4+ cell count from baseline was 201.2 cells/mm 3.

14.4 Treatment-Naïve Pediatric Subjects (2 to less than 12 Years of Age)

The pharmacokinetics, safety, tolerability and efficacy of EDURANT and EDURANT PED weight-adjusted doses 25, 15 and 12.5 mg once daily in combination with an investigator-selected BR containing two NRTIs, was evaluated in trial TMC278-C213 Cohort 2, a single-arm, open-label Phase 2 trial in antiretroviral treatment-naïve HIV-1 infected pediatric subjects 6 to less than 12 years of age and weighing at least 17 kg. The Week 48 analysis included 18 subjects, 17 (94%) subjects completed the 48-week treatment period, and 1 (6%) subject discontinued the study early due to reaching a virologic endpoint. The 18 subjects had a median age of 9 years (range 6 to 11 years) and the median weight at baseline was 25 kg (range 17 to 51 kg). 89% were Black and 39% were female. The median baseline plasma viral load was 55,400 (range 567–149,000) copies/mL, and the median absolute baseline CD4+ cell count was 432.5 (range 12–2,068) cells/µL.

The number of subjects with HIV-1 RNA <50 copies/mL at Week 48 was 13/18 (72%), while 3/18 (17%) subjects had HIV-1 RNA ≥50 copies/mL at Week 48 [see Microbiology (12.4)] . Two out of 18 (11%) participants in the 15 mg once daily (20 to ≤25 kg) dose-weight group had missing viral load data at Week 48 but remained on study. The viral load for these 2 subjects was <50 copies/mL, post-Week 48. The mean increase (SE) in CD4+ from baseline was 215.9 (62.42) cells/µL at Week 48.

The safety and efficacy of EDURANT and EDURANT PED in treatment naïve pediatric subjects 2 to less than 6 years of age is supported by evidence from adequate and well-controlled studies of EDURANT in adults with additional population pharmacokinetic data from adults and pediatric subjects 6 years and older [see Use in Specific Populations (8.4) and Clinical Pharmacology (12.3)] .

Severe Skin and Hypersensitivity Reactions

Advise patients to immediately contact their healthcare provider if they develop a rash. Instruct patients to immediately stop taking EDURANT or EDURANT PED and seek medical attention if they develop a rash associated with any of the following symptoms as it may be a sign of more serious reactions such as DRESS severe hypersensitivity: fever, blisters, mucosal involvement, eye inflammation (conjunctivitis), severe allergic reaction causing a swelling of the face, eyes, lips, mouth, tongue or throat, which may lead to difficulty swallowing or breathing, and any signs and symptoms of liver problems as it may be a sign of a more serious reaction. Advise patients that if severe rash occurs, they will be closely monitored, laboratory tests will be performed and appropriate therapy will be initiated [see Warnings and Precautions (5.1)] .

Hepatotoxicity

Inform patients that hepatotoxicity has been reported with EDURANT. Inform patients that laboratory monitoring for hepatotoxicity during therapy with EDURANT or EDURANT PED is recommended, especially for patients with underlying liver disease such as hepatitis B or C virus infection [see Warnings and Precautions (5.2)].

Depressive Disorders

Inform patients that depressive disorders (depressed mood, depression, dysphoria, major depression, mood altered, negative thoughts, suicide attempt, suicidal ideation) have been reported with EDURANT. Advise patients to seek immediate medical evaluation if they experience depressive symptoms [see Warnings and Precautions (5.3)] .

Drug Interactions

EDURANT or EDURANT PED may interact with many drugs; therefore, advise patients to report to their healthcare provider the use of any other prescription or nonprescription medication or herbal products, including St. John's wort [see Contraindications (4), Warnings and Precautions (5.4), and Drug Interactions (7)] .

For patients concomitantly receiving rifabutin, the EDURANT dose should be increased to 50 mg once daily, taken with a meal. When rifabutin coadministration is stopped, the EDURANT dose should be decreased to 25 mg once daily, taken with a meal [see Dosage and Administration (2.7)] .

Immune Reconstitution Syndrome

Advise patients to inform their healthcare provider immediately of any signs or symptoms of infection as inflammation from previous infection may occur soon after combination antiretroviral therapy, including when EDURANT or EDURANT PED is started [see Warnings and Precautions (5.5)].

EDURANT Tablets and EDURANT PED Tablets for Oral Suspension Are Not Substitutable

Advise patients that EDURANT and EDURANT PED have differing pharmacokinetic profiles and are not substitutable on a milligram-per-milligram basis. Advise patients or their care providers that patients switching from EDURANT PED tablets for oral suspension to EDURANT tablets must adjust the dose [see Dosage and Administration (2.1, 2.3) and Warnings and Precautions (5.6)].

To avoid a dosing error from using the wrong formulation of EDURANT, strongly advise patients and caregivers to visually inspect the tablets to verify the correct formulation each time the prescription is filled [see Dosage and Administration (2), Warnings and Precautions (5.6), and How Supplied/Storage and Handling (16)].

Administration Instructions

Advise patients to take EDURANT or EDURANT PED with a meal once a day as prescribed. A protein drink or yogurt alone does not replace a meal [see Clinical Pharmacology (12.3)] . EDURANT and EDURANT PED must always be used in combination with other antiretroviral drugs. Advise patients not to alter the dose of EDURANT or EDURANT PED or discontinue therapy without consulting their physician.

Inform patients and caregivers that EDURANT PED tablets for oral suspension should be dispersed in drinking water and should not be crushed, chewed, or swallowed whole [see Dosage and Administration (2.4)].

If the patient misses a dose of EDURANT or EDURANT PED within 12 hours of the time it is usually taken, advise the patient to take EDURANT or EDURANT PED with a meal as soon as possible and then take the next dose of EDURANT or EDURANT PED at the regularly scheduled time. If a patient misses a dose of EDURANT or EDURANT PED by more than 12 hours, advise the patient to not take the missed dose, but resume the usual dosing schedule. Inform the patient that he or she should not take more or less than the prescribed dose of EDURANT or EDURANT PED at any one time.

Pregnancy Registry

Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to EDURANT during pregnancy [see Use in Specific Populations (8.1)].

Lactation

Inform individuals with HIV-1 infection that the potential risks of breastfeeding include: (1) HIV-1 transmission (in HIV-1-negative infants), (2) developing viral resistance (in HIV-1-positive infants), and (3) adverse reactions in a breastfed infant similar to those seen in adults [see Use in Specific Populations (8.2)] .
