Warnings and precautions

Severe, potentially life threatening and fatal skin reactions have been reported. This includes cases of Stevens-Johnson syndrome, hypersensitivity reaction, toxic epidermal necrolysis and erythema multiforme. Immediately discontinue treatment if severe hypersensitivity, severe rash or rash with systemic symptoms or liver transaminase elevations develops and monitor clinical status, including liver transaminases closely. ( 5.1 ) Monitor for immune reconstitution syndrome and fat redistribution. ( 5.3 , 5.4 ) 5.1 Severe Skin and Hypersensitivity Reactions Severe, potentially life-threatening and fatal skin reactions have been reported. In clinical trials, these include cases of Stevens-Johnson syndrome, toxic epidermal necrolysis and erythema multiforme. Hypersensitivity reactions including Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) have also been reported and were characterized by rash, constitutional findings, and sometimes organ dysfunction, including hepatic failure. In Phase 3 clinical trials, Grade 3 and 4 rashes were reported in 1.3% of subjects receiving INTELENCE compared to 0.2% of placebo subjects. A total of 2.2% of HIV-1-infected subjects receiving INTELENCE discontinued from Phase 3 trials due to rash [see Adverse Reactions (6.1) ] . Rash occurred most commonly during the first 6 weeks of therapy. The incidence of rash was higher in females [see Adverse Reactions (6.1) ] . Stevens-Johnson syndrome was reported in 1.1% (2/177) of pediatric patients less than 18 years of age receiving INTELENCE in combination with other HIV-1 antiretroviral agents in an observational study. Discontinue INTELENCE immediately if signs or symptoms of severe skin reactions or hypersensitivity reactions develop (including, but not limited to, severe rash or rash accompanied by fever, general malaise, fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, facial edema, hepatitis, eosinophilia, angioedema). Clinical status including liver transaminases should be monitored and appropriate therapy initiated. Delay in stopping INTELENCE treatment after the onset of severe rash may result in a life-threatening reaction. 5.2 Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions The concomitant use of INTELENCE and other drugs may result in potentially significant drug interactions, some of which may lead to [see Drug Interactions (7.3)] : Loss of therapeutic effect of concomitant drug or INTELENCE and possible development of resistance. Possible clinically significant adverse reactions from greater exposures of INTELENCE or other concomitant drugs. See Table 4 for 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 INTELENCE therapy and review concomitant medications during INTELENCE therapy. 5.3 Immune Reconstitution Syndrome Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including INTELENCE. 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 avium infection, cytomegalovirus, Pneumocystis jiroveci pneumonia (PCP) 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. 5.4 Fat Redistribution 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.

Side effects

The following adverse reactions are described in greater detail in other sections: Severe skin and hypersensitivity reactions [see Warnings and Precautions (5.1) ] . Immune reconstitution syndrome [see Warnings and Precautions (5.3) ] . The most common adverse drug reactions of moderate to severe intensity (at least 2%) which occurred at a higher rate than placebo in adults are rash and peripheral neuropathy. ( 6.1 ) The most common adverse drug reactions in at least 2% of pediatric patients are rash and diarrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Janssen Products, LP at 1-800-JANSSEN (1-800-526-7736) 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. Clinical Trials Experience in Adults The safety assessment is based on all data from 1203 subjects in the Phase 3 placebo-controlled trials, TMC125-C206 and TMC125-C216, conducted in antiretroviral treatment-experienced HIV-1-infected adult subjects, 599 of whom received INTELENCE (200 mg twice daily). In these pooled trials, the median exposure for subjects in the INTELENCE arm and placebo arm was 52.3 and 51.0 weeks, respectively. Discontinuations due to adverse drug reactions (ADRs) were 5.2% in the INTELENCE arm and 2.6% in the placebo arm. The most frequently reported ADR at least Grade 2 in severity was rash (10.0%). Stevens-Johnson syndrome, drug hypersensitivity reaction and erythema multiforme were reported in less than 0.1% of subjects during clinical development with INTELENCE [see Warnings and Precautions (5.1) ] . A total of 2.2% of HIV-1-infected subjects in Phase 3 trials receiving INTELENCE discontinued due to rash. In general, in clinical trials, rash was mild to moderate, occurred primarily in the second week of therapy, and was infrequent after Week 4. Rash generally resolved within 1 to 2 weeks on continued therapy. The incidence of rash was higher in women compared to men in the INTELENCE arm in the Phase 3 trials (rash ≥ Grade 2 was reported in 9/60 [15.0%] women versus 51/539 [9.5%] men; discontinuations due to rash were reported in 3/60 [5.0%] women versus 10/539 [1.9%] men) [see Warnings and Precautions (5.1) ] . Patients with a history of NNRTI-related rash did not appear to be at increased risk for the development of INTELENCE-related rash compared to patients without a history of NNRTI-related rash. Common Adverse Reactions Clinical ADRs of moderate intensity or greater (greater than or equal to Grade 2) and reported in at least 2% of subjects treated with INTELENCE and occurring at a higher rate compared to placebo (excess of 1%) are presented in Table 2. Laboratory abnormalities considered ADRs are included in Table 3. Table 2: Adverse Drug Reactions (Grades 2 to 4) in at Least 2% of Adult Subjects (Pooled TMC125-C206 and TMC125-C216 Trials) Preferred Term INTELENCE + BR N=599 % Placebo + BR N=604 % N=total number of subjects per treatment group; BR=background regimen Rash 10% 3% Peripheral neuropathy 4% 2% Less Common Adverse Reactions Treatment-emergent ADRs occurring in less than 2% of subjects (599 subjects) receiving INTELENCE and of at least moderate intensity (greater than or equal to Grade 2) are listed below by body system: Cardiac Disorders : myocardial infarction, angina pectoris, atrial fibrillation Ear and Labyrinth Disorders : vertigo Eye Disorders : blurred vision Gastrointestinal Disorders : gastroesophageal reflux disease, flatulence, gastritis, abdominal distension, pancreatitis, constipation, dry mouth, hematemesis, retching, stomatitis General Disorders and Administration Site Conditions : sluggishness Hematologic Disorders : hemolytic anemia Hepatobiliary Disorders : hepatic failure, hepatomegaly, cytolytic hepatitis, hepatic steatosis, hepatitis Immune System Disorders : drug hypersensitivity, immune reconstitution syndrome Metabolism and Nutrition Disorders : diabetes mellitus, anorexia, dyslipidemia Nervous System Disorders : paresthesia, somnolence, convulsion, hypoesthesia, amnesia, syncope, disturbance in attention, hypersomnia, tremor Psychiatric Disorders : anxiety, sleep disorders, abnormal dreams, confusional state, disorientation, nervousness, nightmares Renal and Urinary Disorders: acute renal failure Reproductive System and Breast Disorders : gynecomastia Respiratory, Thoracic and Mediastinal Disorders : exertional dyspnea, bronchospasm Skin and Subcutaneous Tissue Disorders : night sweats, lipohypertrophy, prurigo, hyperhidrosis, dry skin, swelling face Additional ADRs of at least moderate intensity observed in other trials were acquired lipodystrophy, angioneurotic edema, erythema multiforme and hemorrhagic stroke, each reported in no more than 0.5% of subjects. Laboratory Abnormalities in Treatment-Experienced Patients Selected Grade 2 to Grade 4 laboratory abnormalities that represent a worsening from baseline observed in adult subjects treated with INTELENCE are presented in Table 3.

Drug interactions

Co-administration of INTELENCE with other drugs can alter the concentrations of other drugs and other drugs may alter the concentrations of etravirine. The potential drug-drug interactions must be considered prior to and during therapy. ( 7 , 12.3 ) 7.1 Potential for Other Drugs to Affect INTELENCE Etravirine is a substrate of CYP3A, CYP2C9, and CYP2C19. Therefore, co-administration of INTELENCE with drugs that induce or inhibit CYP3A, CYP2C9, and CYP2C19 may alter the therapeutic effect or adverse reaction profile of INTELENCE (see Table 4 ) [see Clinical Pharmacology (12.3) ]. 7.2 Potential for INTELENCE to Affect Other Drugs Etravirine is an inducer of CYP3A and inhibitor of CYP2C9, CYP2C19 and P-glycoprotein (P-gp). Therefore, co-administration of drugs that are substrates of CYP3A, CYP2C9 and CYP2C19 or are transported by P-gp with INTELENCE may alter the therapeutic effect or adverse reaction profile of the co-administered drug(s) (see Table 4 ) [see Clinical Pharmacology (12.3) ]. 7.3 Significant Drug Interactions Table 4 shows significant drug interactions based on which, alterations in dose or regimen of INTELENCE and/or co-administered drug may be recommended. Drugs that are not recommended for co-administration with INTELENCE are also included in Table 4 [see Clinical Pharmacology (12.3) ] . Table 4: Significant Drug Interactions Concomitant Drug Class: Drug Name Effect on Concentration of Etravirine or Concomitant Drug Clinical Comment ↑ = increase; ↓ = decrease; ↔ = no change HIV-antiviral agents: integrase strand inhibitors dolutegravir The interaction between INTELENCE and the drug was evaluated in a clinical study. All other drug interactions shown are predicted. ↓ dolutegravir ↔ etravirine Etravirine significantly reduced plasma concentrations of dolutegravir. Using cross - study comparisons to historical pharmacokinetic data for etravirine, dolutegravir did not appear to affect the pharmacokinetics of etravirine. dolutegravir/darunavir/ritonavir ↓ dolutegravir ↔ etravirine The effect of etravirine on dolutegravir plasma concentrations was mitigated by co-administration of darunavir/ritonavir or lopinavir/ritonavir, and is expected to be mitigated by atazanavir/ritonavir. Dolutegravir should only be used with INTELENCE when co-administered with atazanavir/ritonavir, darunavir/ritonavir, or lopinavir/ritonavir. dolutegravir/lopinavir/ritonavir ↔ dolutegravir ↔ etravirine HIV-antiviral agents: non-nucleoside reverse transcriptase inhibitors (NNRTIs) efavirenz nevirapine ↓ etravirine Combining two NNRTIs has not been shown to be beneficial. Concomitant use of INTELENCE with efavirenz or nevirapine may cause a significant decrease in the plasma concentrations of etravirine and loss of therapeutic effect of INTELENCE. Co-administration of INTELENCE and other NNRTIs is not recommended. delavirdine ↑ etravirine Combining two NNRTIs has not been shown to be beneficial. INTELENCE and delavirdine should not be co-administered. rilpivirine ↓ rilpivirine ↔ etravirine Combining two NNRTIs has not been shown to be beneficial. Co-administration of INTELENCE and rilpivirine is not recommended. HIV-antiviral agents: protease inhibitors (PIs) atazanavir (without ritonavir) ↓ atazanavir Co-administration of INTELENCE and atazanavir without low-dose ritonavir is not recommended. atazanavir/ritonavir ↓ atazanavir ↔ etravirine Concomitant use of INTELENCE with atazanavir/ritonavir decreased atazanavir C min but it is not considered clinically relevant. The mean systemic exposure (AUC) of etravirine after co-administration of INTELENCE with atazanavir/ritonavir in HIV-infected subjects was similar to the mean systemic exposure of etravirine observed in the Phase 3 trials after co-administration of INTELENCE and darunavir/ritonavir (as part of the background regimen). INTELENCE and atazanavir/ritonavir can be co-administered without dose adjustments. atazanavir/cobicistat ↓ atazanavir ↓ cobicistat Co-administration of INTELENCE with atazanavir/cobicistat is not recommended because it may result in loss of therapeutic effect and development of resistance to atazanavir. darunavir/ritonavir ↓ etravirine The mean systemic exposure (AUC) of etravirine was reduced when INTELENCE was co-administered with darunavir/ritonavir. Because all subjects in the Phase 3 trials received darunavir/ritonavir as part of the background regimen and etravirine exposures from these trials were determined to be safe and effective, INTELENCE and darunavir/ritonavir can be co-administered without dose adjustments. darunavir/cobicistat ↓ cobicistat darunavir: effect unknown Co-administration of INTELENCE with darunavir/cobicistat is not recommended because it may result in loss of therapeutic effect and development of resistance to darunavir. fosamprenavir (without ritonavir) ↑ amprenavir Concomitant use of INTELENCE with fosamprenavir without low-dose ritonavir may cause a significant alteration in the plasma concentration of amprenavir. Co-administration of INTELENCE and fosamprenavir without low-dose ritonavir is not recommended. fosamprenavir/ritonavir ↑ amprenavir Due to a significant increase in the systemic exposure of amprenavir, the appropriate doses of the combination of INTELENCE and fosamprenavir/ritonavir have not been established. Co-administration of INTELENCE and fosamprenavir/ritonavir is not recommended. indinavir (without ritonavir) ↓ indinavir Concomitant use of INTELENCE with indinavir without low-dose ritonavir may cause a significant alteration in the plasma concentration of indinavir. Co-administration of INTELENCE and indinavir without low-dose ritonavir is not recommended. lopinavir/ritonavir ↓ etravirine The mean systemic exposure (AUC) of etravirine was reduced after co-administration of INTELENCE with lopinavir/ritonavir (tablet).

Use in specific populations

Lactation: Breastfeeding is not recommended due to the potential for HIV-1 transmission. ( 8.2 ) 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in individuals exposed to INTELENCE during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) at 1-800-258-4263. Risk Summary Prospective pregnancy data from clinical trials and the APR are not sufficient to adequately assess the risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Etravirine use during pregnancy has been evaluated in a limited number of individuals as reported by the APR, and available data show 1 birth defect in 66 first trimester exposures to etravirine-containing regimens (see Data ) . The estimated background rate for major birth defects is 2.7% in the U.S. reference population of the Metropolitan Atlanta Congenital Defects Program (MACDP). The rate of miscarriage is not reported in the APR. The estimated background rate of miscarriage in clinically recognized pregnancies in the U.S. general population is 15–20%. The background risk of major birth defects and miscarriage for the indicated population is unknown. In animal reproduction studies, no adverse developmental effects were observed with orally administered etravirine at exposures equivalent to those at the maximum recommended human dose (MRHD) of 400 mg daily (see Data ) . Data Human Data Based on prospective reports to the APR of 116 live births following exposure to etravirine-containing regimens during pregnancy (including 66 exposed in the first trimester and 38 exposed in the second/third trimester), the number of birth defects in live births for etravirine was 1 out of 66 with first trimester exposure and 0 out of 38 with second/third trimester exposure. Prospective reports from the APR of overall major birth defects in pregnancies exposed to INTELENCE is compared with a U.S. background major birth defect rate. Methodological limitations of the APR include the use of MACDP as the external comparator group. Limitations of using an external comparator include differences in methodology and populations, as well as confounding due to the underlying disease; these limitations preclude an accurate comparison of outcomes. INTELENCE (200 mg twice daily) in combination with other antiretroviral agents was evaluated in a clinical trial enrolling 15 pregnant subjects during the second and third trimesters of pregnancy and postpartum. Thirteen subjects completed the trial through postpartum period (6–12 weeks after delivery). The pharmacokinetic data demonstrated that exposure to total etravirine was generally higher during pregnancy compared with postpartum [see Clinical Pharmacology (12.3) ] . Among subjects who were virologically suppressed (HIV-1 RNA less than 50 copies/mL) at baseline (9/13), virologic suppression was maintained through the third trimester and postpartum period. Among subjects with HIV-1 RNA greater than 50 copies/mL and less than 400 copies/mL at baseline (3/13), viral loads remained less than 400 copies/mL. In one subject with HIV-1 RNA greater than 1,000 copies/mL at baseline (1/13), HIV-1 RNA remained greater than 1,000 copies/mL during the study period. Thirteen infants were born to 13 HIV-infected pregnant individuals in this study. HIV-1 test results were not available for 2 infants. Among the eleven infants with HIV-1 test results available, who were born to 11 HIV-infected pregnant individuals who completed the study, all had test results that were negative for HIV-1 at the time of delivery. No unexpected safety findings were observed compared with the known safety profile of INTELENCE in non-pregnant adults. Animal Data Reproductive and developmental toxicity studies were performed in rats (at 250, 500 and 1,000 mg/kg/day) and rabbits (at 125, 250 and 375 mg/kg/day) administered etravirine on gestation days 6 through 16, and 6 through 19, respectively. In both species, no treatment-related embryo-fetal effects were observed. In addition, no treatment-related effects were observed in a pre- and postnatal development study performed in rats administered oral doses up to 500 mg/kg/day on gestation days 7 through lactation day 7. The systemic drug exposures achieved at the high dose in these animal studies were equivalent to those at the MRHD. 8.2 Lactation Risk Summary The Centers for Disease Control and Prevention recommend that HIV-1-infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV. Based on limited data, etravirine has been shown to be present in human breast milk. There are no data on the effects of etravirine on the breastfed infant, or the effects of etravirine on milk production. Because of the potential for (1) HIV-1 transmission (in HIV-negative infants), (2) developing viral resistance (in HIV-positive infants) and (3) adverse reactions in breastfed infants similar to those seen in adults, instruct mothers not to breastfeed if they are receiving INTELENCE. 8.4 Pediatric Use The safety and effectiveness of INTELENCE have been established for the treatment of HIV-infected pediatric patients from 2 years of age to less than 18 years [see Indications and Usage (1) and Dosage and Administration (2.3) ] . Use of INTELENCE in pediatric patients 2 years to less than 18 years of age is supported by evidence from adequate and well-controlled studies of INTELENCE in adults with additional data from two Phase 2 trials in treatment-experienced pediatric subjects, TMC125-C213, 6 years to less than 18 years of age (N=101) and TMC125-C234/IMPAACT P1090, 2 years to less than 6 years of age (N=20). Both studies were open-label, single arm trials of etravirine plus an optimized background regimen.

Pediatric use

8.4 Pediatric Use The safety and effectiveness of INTELENCE have been established for the treatment of HIV-infected pediatric patients from 2 years of age to less than 18 years [see Indications and Usage (1) and Dosage and Administration (2.3) ] . Use of INTELENCE in pediatric patients 2 years to less than 18 years of age is supported by evidence from adequate and well-controlled studies of INTELENCE in adults with additional data from two Phase 2 trials in treatment-experienced pediatric subjects, TMC125-C213, 6 years to less than 18 years of age (N=101) and TMC125-C234/IMPAACT P1090, 2 years to less than 6 years of age (N=20). Both studies were open-label, single arm trials of etravirine plus an optimized background regimen. In clinical trials, the safety, pharmacokinetics, and efficacy were comparable to that observed in adults except for rash (greater than or equal to Grade 2) which was observed more frequently in pediatric subjects [see Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14.2) ] . Postmarketing reports of Stevens-Johnson syndrome in pediatric patients receiving INTELENCE have been reported [see Warnings and Precautions (5.1) , and Adverse Reactions (6.2) ] . Treatment with INTELENCE is not recommended in pediatric patients less than 2 years of age [see Clinical Pharmacology (12.3) ] . Five HIV-infected subjects from 1 year to < 2 years of age were enrolled in TMC125-C234/IMPAACT P1090. Etravirine exposure was lower than reported in HIV-infected adults (AUC 12h geometric mean ratio [90% CI] was 0.59 [0.34, 1.01] for pediatric subjects from 1 year to < 2 years of age compared to adults). Virologic failure at Week 24 (confirmed HIV-RNA greater than or equal to 400 copies/mL) occurred in 3 of 4 evaluable subjects who discontinued before or had reached Week 24. Genotypic and phenotypic resistance to etravirine developed in 1 of the 3 subjects who experienced virologic failure.

Geriatric use

8.5 Geriatric Use Clinical studies of INTELENCE did not include sufficient numbers of subjects aged 65 years of age and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger subjects. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy [see Clinical Pharmacology (12.3) ] .

Overdosage

There is no specific antidote for overdose with INTELENCE. Human experience of overdose with INTELENCE is limited. The highest dose studied in healthy volunteers was 400 mg once daily. Treatment of overdose with INTELENCE consists of general supportive measures including monitoring of vital signs and observation of the clinical status of the patient. Because etravirine is highly protein bound, dialysis is unlikely to result in significant removal of the active substance.

Patient information

Advise the patient to read the FDA-approved patient labeling (Patient Information). Administration Advise patients to take INTELENCE following a meal twice a day on a regular dosing schedule, as missed doses can result in development of resistance. The type of food does not affect the exposure to etravirine. Inform patients not to take more or less than the prescribed dose of INTELENCE or discontinue therapy with INTELENCE without consulting their physician. INTELENCE must always be used in combination with other antiretroviral drugs [see Dosage and Administration (2.4) ]. Advise patients to swallow the INTELENCE tablet(s) whole with a liquid such as water. Instruct patients not to chew the tablets. Patients who are unable to swallow the INTELENCE tablet(s) whole may disperse the tablet(s) in water. The patient should be instructed to do the following: place the tablet(s) in 5 mL (1 teaspoon) of water, or at least enough liquid to cover the medication, stir well until the water looks milky, add approximately 15 mL (1 tablespoon) of liquid. Water may be used, but orange juice or milk may improve taste. Patients should not place the tablets in orange juice or milk without first adding water. The use of warm (temperature greater than 104°F [greater than 40°C]) or carbonated beverages should be avoided. drink the mixture immediately, rinse the glass several times with orange juice, milk or water and completely swallow the rinse each time to make sure the patient takes the entire dose. Severe Skin Reactions Inform patients that severe and potentially life-threatening rash has been reported with INTELENCE. Rash has been reported most commonly in the first 6 weeks of therapy. Advise patients to immediately contact their healthcare provider if they develop rash. Instruct patients to immediately stop taking INTELENCE and seek medical attention if they develop a rash associated with any of the following symptoms as it may be a sign of a more serious reaction such as Stevens-Johnson syndrome, toxic epidermal necrolysis or severe hypersensitivity: fever, generally ill feeling, extreme tiredness, muscle or joint aches, blisters, oral lesions, eye inflammation, facial swelling, swelling of the eyes, lips, mouth, breathing difficulty, and/or signs and symptoms of liver problems (e.g., yellowing of your skin or whites of your eyes, dark or tea colored urine, pale colored stools/bowel movements, nausea, vomiting, loss of appetite, or pain, aching or sensitivity on your right side below your ribs). Patients should understand that if severe rash occurs, they will be closely monitored, laboratory tests will be ordered and appropriate therapy will be initiated [see Warnings and Precautions (5.1) ] . Drug Interactions INTELENCE 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 Warnings and Precautions (5.2) ] . Immune Reconstitution Syndrome Advise patients to inform their healthcare provider immediately of any symptoms of infection, as in some patients with advanced HIV infection (AIDS), signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started [see Warnings and Precautions (5.3) ]. Fat Redistribution Inform patients that redistribution or accumulation of body fat may occur in patients receiving antiretroviral therapy, including INTELENCE, and that the cause and long-term health effects of these conditions are not known at this time [see Warnings and Precautions (5.4) ] . Pregnancy Registry Inform patients that there is an antiretroviral pregnancy registry to monitor fetal outcomes of pregnant individuals exposed to INTELENCE [see Use in Specific Populations (8.1) ] . Lactation Instruct mothers with HIV-1 infection not to breastfeed because HIV-1 can be passed to the baby in breast milk [see Use in Specific Populations (8.2) ] .
