COMPLERA ® is indicated as a complete regimen for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 35 kg: as initial therapy in those with no antiretroviral treatment history with HIV-1 RNA less than or equal to 100,000 copies/mL at the start of therapy or to replace a stable antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies/mL) on a stable antiretroviral regimen for at least 6 months with no treatment failure and no known substitutions associated with resistance to the individual components of COMPLERA . COMPLERA, a combination of two nucleoside analog HIV-1 reverse transcriptase inhibitors (emtricitabine and tenofovir disoproxil fumarate) and one non-nucleoside reverse transcriptase inhibitor (rilpivirine), is indicated for use as a complete regimen for the treatment of HIV-1 infection in patients weighing at least 35 kg as initial therapy in those with no antiretroviral treatment history and with HIV-1 RNA less than or equal to 100,000 copies/mL at the start of therapy, or or to replace a stable antiretroviral regiment in those who are virologically suppressed (HIV-1 RNA <50 copies/mL) on a stable antiretroviral regimen for at least 6 months with no treatment failure and no known substitutions associated with resistance to the individual components of COMPLERA. ( 1 , 14 ) Limitations of Use: More rilpivirine-treated subjects with HIV-1 RNA greater than 100,000 copies/mL at the start of therapy experienced virologic failure (HIV-1 RNA ≥50 copies/mL) compared to rilpivirine-treated subjects with HIV-1 RNA less than or equal to 100,000 copies/mL. ( 1 , 14 ) Limitations of Use : More rilpivirine-treated subjects with HIV-1 RNA greater than 100,000 copies/mL at the start of therapy experienced virologic failure (HIV-1 RNA ≥50 copies/mL) compared to rilpivirine-treated subjects with HIV-1 RNA less than or equal to 100,000 copies/mL .

Each COMPLERA tablet contains 200 mg of emtricitabine (FTC), 27.5 mg of rilpivirine hydrochloride (equivalent to 25 mg of rilpivirine [RPV]), and 300 mg of tenofovir disoproxil fumarate (TDF, equivalent to 245 mg of tenofovir disoproxil). The tablets are purplish pink, capsule shaped, film coated, debossed with "GSI" on one side, and plain faced on the other side. Tablets: 200 mg of emtricitabine, 25 mg of rilpivirine, and 300 mg of tenofovir disoproxil fumarate.

Testing: Prior to or when initiating COMPLERA, test for hepatitis B virus infection. Prior to initiation and during treatment with COMPLERA, on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus. Recommended dosage in adults and pediatric patients weighing at least 35 kg: One tablet taken orally once daily with food. For pregnant patients who are already on COMPLERA prior to pregnancy and who are virologically suppressed (HIV-1 RNA less than 50 copies per mL), one tablet taken once daily may be continued. Lower exposures of rilpivirine were observed during pregnancy; therefore, viral load should be monitored closely. Renal impairment: Not recommended in patients with estimated creatinine clearance below 50 mL per minute. Recommended dosage with rifabutin coadministration: an additional 25 mg tablet of rilpivirine (Edurant) once per day taken concomitantly with COMPLERA and with a meal for the duration of the rifabutin coadministration. ( 2.5 , 7.6 , 12.3 ) 2.1 Testing Prior to Initiation and During Treatment with COMPLERA Prior to or when initiating COMPLERA, test patients for hepatitis B virus infection . Prior to initiation of COMPLERA, and during treatment with COMPLERA, on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus

Recommended Dosage COMPLERA is a three-drug fixed dose combination product containing 200 mg of emtricitabine (FTC), 25 mg of rilpivirine (RPV), and 300 mg of tenofovir disoproxil fumarate (TDF). The recommended dosage of COMPLERA in adult and pediatric patients weighing at least 35 kg is one tablet taken orally once daily with food

Recommended Dosage During Pregnancy For pregnant patients who are already on COMPLERA prior to pregnancy and are virologically suppressed (HIV-1 RNA less than 50 copies per mL), one tablet of COMPLERA taken once daily may be continued. Lower exposures of rilpivirine, a component of COMPLERA, were observed during pregnancy, therefore viral load should be monitored closely

Not Recommended in Patients with Moderate or Severe Renal Impairment COMPLERA is not recommended in patients with moderate or severe renal impairment (estimated creatinine clearance below 50 mL per minute)

Recommended Dosage with Rifabutin Coadministration If COMPLERA is coadministered with rifabutin, take an additional 25 mg tablet of rilpivirine (Edurant ® ) with COMPLERA once daily with a meal for the duration of the rifabutin coadministration .

Skin and Hypersensitivity Reactions: Severe skin and hypersensitivity reactions have been reported during postmarketing experience, including cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS). Immediately discontinue treatment if hypersensitivity or rash with systemic symptoms or elevations in hepatic serum biochemistries develops and closely monitor clinical status, including hepatic serum biochemistries. Hepatotoxicity: Hepatic adverse events have been reported in patients receiving a rilpivirine-containing regimen. Monitor liver-associated tests before and during treatment with COMPLERA in patients with underlying hepatic disease or marked elevations in liver-associated tests. Also consider monitoring liver-associated tests in patients without risk factors. Depressive disorders: Severe depressive disorders have been reported. Immediate medical evaluation is recommended for severe depressive disorders. New onset or worsening renal impairment: Can include acute renal failure and Fanconi syndrome. Avoid administering COMPLERA with concurrent or recent use of nephrotoxic drugs. Decreases in bone mineral density (BMD): Consider monitoring BMD in patients with a history of pathologic fracture or other risk factors of osteoporosis or bone loss. Concomitant use of COMPLERA with drugs with a known risk to prolong the QTc interval of the electrocardiogram may increase the risk of Torsade de Pointes. Lactic acidosis/severe hepatomegaly with steatosis: Discontinue treatment in patients who develop symptoms or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity. Immune reconstitution syndrome: May necessitate further evaluation and treatment. 5.1 Severe Acute Exacerbation of Hepatitis B in Patients Coinfected with HIV-1 and HBV Test all patients with HIV-1 for the presence of chronic hepatitis B virus (HBV) before or when initiating antiretroviral therapy . Severe acute exacerbations of hepatitis B (e.g., liver decompensation and liver failure) have been reported in patients who are coinfected with HBV and HIV-1 and have discontinued products containing FTC and/or TDF, two of the components of COMPLERA. Patients coinfected with HIV-1 and HBV who discontinue COMPLERA should be closely monitored with both clinical and laboratory follow-up for at least several months after stopping treatment with COMPLERA. If appropriate, initiation of anti-hepatitis B therapy may be warranted, especially in patients with advanced liver disease or cirrhosis, since posttreatment exacerbation of hepatitis may lead to hepatic decompensation and liver failure

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 RPV-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 1% of subjects receiving RPV plus FTC/TDF. Overall, most rashes were Grade 1 or 2 and occurred in the first four to six weeks of therapy . Discontinue COMPLERA 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

Hepatotoxicity Hepatic adverse events have been reported in patients receiving an RPV-containing regimen. Patients with underlying hepatitis B or C virus infection, or marked elevations in liver-associated tests prior to treatment, may be at increased risk for worsening or development of liver-associated test elevations with use of COMPLERA. A few cases of hepatic toxicity have been reported in adult patients receiving an RPV-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 COMPLERA is recommended in patients with underlying hepatic disease such as hepatitis B or C, or in patients with marked elevations in liver-associated tests prior to treatment initiation. Liver-associated test monitoring should also be considered for patients without pre-existing hepatic dysfunction or other risk factors

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 RPV. Patients with severe depressive symptoms should seek immediate medical evaluation to assess the possibility that the symptoms are related to COMPLERA, 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 RPV (n=686) or efavirenz (EFV, n=682) was 9% and 8%, respectively. Most events were mild or moderate in severity. The incidence of Grades 3 and 4 depressive disorders (regardless of causality) was 1% for both RPV and EFV. The incidence of discontinuation due to depressive disorders among RPV or EFV 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 RPV arm. During the Phase 2 trial in pediatric subjects 12 to less than 18 years of age (N=36) receiving RPV 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

New Onset or Worsening Renal Impairment Renal impairment, including cases of acute renal failure and Fanconi syndrome (renal tubular injury with severe hypophosphatemia), has been reported with the use of TDF . Prior to initiation of COMPLERA, and during treatment with COMPLERA, on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus. COMPLERA should be avoided with concurrent or recent use of a nephrotoxic agent (e.g., high-dose or multiple nonsteroidal anti-inflammatory drugs [NSAIDs]) . Cases of acute renal failure after initiation of high-dose or multiple NSAIDs have been reported in HIV-infected patients with risk factors for renal dysfunction who appeared stable on TDF. Some patients required hospitalization and renal replacement therapy. Alternatives to NSAIDs should be considered, if needed, in patients at risk for renal dysfunction. Persistent or worsening bone pain, pain in extremities, fractures, and/or muscular pain or weakness may be manifestations of proximal renal tubulopathy and should prompt an evaluation of renal function in at-risk patients. Emtricitabine and TDF are principally eliminated by the kidney; however, RPV is not. Since COMPLERA is a combination product and the dose of the individual components cannot be altered, COMPLERA is not recommended in patients with estimated creatinine clearance below 50 mL per minute

Bone Loss and Mineralization Defects Bone Mineral Density In clinical trials in HIV-1-infected adults, TDF, a component of COMPLERA, was associated with slightly greater decreases in bone mineral density (BMD) and increases in biochemical markers of bone metabolism, suggesting increased bone turnover relative to comparators. Serum parathyroid hormone levels and 1,25 Vitamin D levels were also higher in subjects receiving TDF. Clinical trials evaluating TDF in pediatric and adolescent subjects were conducted. Under normal circumstances, BMD increases rapidly in pediatric patients. In HIV-1-infected subjects aged 2 years to less than 18 years, bone effects were similar to those observed in adult subjects and suggest increased bone turnover. Total body BMD gain was less in the TDF-treated HIV-1-infected pediatric subjects as compared to the control groups. Similar trends were observed in chronic hepatitis B-infected adolescent subjects aged 12 years to less than 18 years. In all pediatric trials, skeletal growth (height) appeared to be unaffected. The effects of TDF-associated changes in BMD and biochemical markers on long-term bone health and future fracture risk are unknown. Assessment of BMD should be considered for adult and pediatric patients who have a history of pathologic bone fracture or other risk factors for osteoporosis or bone loss. Although the effect of supplementation with calcium and Vitamin D was not studied, such supplementation may be beneficial for all patients. If bone abnormalities are suspected, then appropriate consultation should be obtained. Mineralization Defects Cases of osteomalacia associated with proximal renal tubulopathy, manifested as bone pain or pain in extremities and which may contribute to fractures, have been reported in association with the use of TDF . Arthralgias and muscle pain or weakness have also been reported in cases of proximal renal tubulopathy. Hypophosphatemia and osteomalacia secondary to proximal renal tubulopathy should be considered in patients at risk of renal dysfunction who present with persistent or worsening bone or muscle symptoms while receiving products containing TDF

Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions The concomitant use of COMPLERA and other drugs may result in potentially significant drug interactions, some of which may lead to : Loss of therapeutic effect of COMPLERA and possible development of resistance due to reduced exposure to RPV. Possible clinically significant adverse reaction from greater exposures of components of COMPLERA. In healthy subjects, 75 mg once daily and 300 mg once daily doses of RPV (3 times and 12 times the dose in COMPLERA) have been shown to prolong the QTc interval of the electrocardiogram. Consider alternatives to COMPLERA when coadministered with a drug that is known to have a risk of Torsade de Pointes . 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 COMPLERA therapy and review concomitant medications during COMPLERA therapy

Lactic Acidosis/Severe Hepatomegaly with Steatosis Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogs, including TDF and FTC, components of COMPLERA, alone or in combination with other antiretrovirals. Treatment with COMPLERA should be suspended in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity (which may include hepatomegaly and steatosis even in the absence of marked transaminase elevations)

Immune Reconstitution Syndrome Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including the components of COMPLERA. 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 jirovecii 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.

COMPLERA is a complete regimen for the treatment of HIV-1 infection; therefore, coadministration with other antiretroviral medications for treatment of HIV-1 infection is not recommended. Consult the Full Prescribing Information prior to and during treatment for important drug interactions. ( 4 , 5.7 , 7 ) 7.1 Not Recommended with Other Antiretroviral Medications Because COMPLERA is a complete regimen, coadministration with other antiretroviral medications for the treatment of HIV-1 infection is not recommended. Comprehensive information regarding potential drug-drug interactions with other antiretroviral medications is not provided. This section describes clinically relevant drug interactions with COMPLERA. Drug interaction studies were conducted with the components of COMPLERA (FTC, RPV, and TDF as single agents) or with COMPLERA as a combination product

Drugs Inducing or Inhibiting CYP3A Enzymes Rilpivirine is primarily metabolized by cytochrome P450 (CYP) 3A, and drugs that induce or inhibit CYP3A may thus affect the clearance of RPV . Coadministration of RPV and drugs that induce CYP3A may result in decreased plasma concentrations of RPV and loss of virologic response and possible resistance to RPV or to the class of NNRTIs. Coadministration of RPV and drugs that inhibit CYP3A may result in increased plasma concentrations of RPV

Drugs Increasing Gastric pH Coadministration of RPV with drugs that increase gastric pH may decrease plasma concentrations of RPV and loss of virologic response and possible resistance to RPV or to the class of NNRTIs. Use of RPV with proton pump inhibitors is contraindicated and use of RPV with H 2 -receptor antagonists requires staggered administration

Drugs Affecting Renal Function Because FTC and tenofovir are primarily eliminated by the kidneys through a combination of glomerular filtration and active tubular secretion, coadministration of COMPLERA with drugs that reduce renal function or compete for active tubular secretion may increase serum concentrations of FTC, tenofovir, and/or other renally eliminated drugs. Some examples of drugs that are eliminated by active tubular secretion include, but are not limited to, acyclovir, adefovir dipivoxil, cidofovir, ganciclovir, valacyclovir, valganciclovir, aminoglycosides (e.g., gentamicin), and high-dose or multiple NSAIDs

QT Prolonging Drugs There is limited information available on the potential for a pharmacodynamic interaction between RPV 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 doses of RPV (3 times and 12 times the dose in COMPLERA) have been shown to prolong the QTc interval of the electrocardiogram . Consider alternatives to COMPLERA when coadministered with a drug with a known risk of Torsade de Pointes

Significant Drug Interactions Important drug interaction information for COMPLERA is summarized in Table 4. The drug interactions described are based on studies conducted with FTC, RPV, or TDF as individual medications or with COMPLERA as a combination product, or are potential drug interactions .

Drug Interactions Concomitant Drug Class: Drug Name Effect on Concentration Increase = ↑; Decrease = ↓; No Effect = ↔ Clinical Comment Antacids: antacids (e.g., aluminum, magnesium hydroxide, or calcium carbonate) ↔ RPV (antacids taken at least 2 hours before or at least 4 hours after RPV) ↓ RPV (concomitant intake) Administer antacids at least 2 hours before or at least 4 hours after COMPLERA. Anticonvulsants: carbamazepine oxcarbazepine phenobarbital phenytoin ↓ RPV Coadministration is contraindicated due to potential for loss of virologic response and development of resistance. Antimycobacterials: rifampin rifapentine ↓ RPV Coadministration is contraindicated due to potential for loss of virologic response and development of resistance. rifabutin ↓ RPV The interaction was evaluated in a clinical study. All other drug-drug interactions shown are predicted. If COMPLERA is coadministered with rifabutin, an additional 25 mg tablet of RPV (Edurant) once per day is recommended to be taken concomitantly with COMPLERA and with a meal for the duration of rifabutin coadministration. Azole Antifungal Agents: fluconazole itraconazole ketoconazole posaconazole voriconazole ↑ RPV , This interaction study has been performed with a dose higher than the recommended dose for RPV assessing the maximal effect on the coadministered drug. The dosing recommendation is applicable to the recommended dose of RPV 25 mg once daily. ↓ ketoconazole , No dose adjustment is required when COMPLERA is coadministered with azole antifungal agents. Clinically monitor for breakthrough fungal infections when azole antifungals are coadministered with COMPLERA. Glucocorticoid (systemic): dexamethasone (more than a single-dose treatment) ↓ RPV Coadministration is contraindicated due to potential for loss of virologic response and development of resistance. Hepatitis C Antiviral Agents: ledipasvir/sofosbuvir sofosbuvir/velpatasvir sofosbuvir/velpatasvir/voxilaprevir ↑ tenofovir Patients receiving COMPLERA concomitantly with HARVONI ® (ledipasvir/sofosbuvir), EPCLUSA ® (sofosbuvir/velpatasvir), or VOSEVI ® (sofosbuvir/velpatasvir/voxilaprevir) should be monitored for adverse reactions associated with TDF. H 2 -Receptor Antagonists: cimetidine famotidine nizatidine ranitidine ↔ RPV , (famotidine taken 12 hours before RPV or 4 hours after RPV) ↓ RPV , (famotidine taken 2 hours before RPV) Administer H 2 -receptor antagonists at least 12 hours before or at least 4 hours after COMPLERA. Herbal Products: St John's wort ( Hypericum perforatum ) ↓ RPV Coadministration is contraindicated due to potential for loss of virologic response and development of resistance. Macrolide or Ketolide Antibiotics: clarithromycin erythromycin telithromycin ↑ RPV ↔ clarithromycin ↔ erythromycin ↔ telithromycin Where possible, alternatives such as azithromycin should be considered. Narcotic Analgesics : methadone ↓ R(–) methadone ↓ S(+) methadone ↔ RPV ↔ methadone (when used with tenofovir) No dose adjustments are required when initiating coadministration of methadone with COMPLERA. However, clinical monitoring is recommended as methadone maintenance therapy may need to be adjusted in some patients. Proton Pump Inhibitors: e.g., dexlansoprazole esomeprazole lansoprazole omeprazole pantoprazole rabeprazole ↓ RPV Coadministration is contraindicated due to potential for loss of virologic response and development of resistance
