Monitoring Parameters

CBC with differential, reticulocyte count, creatine kinase, CD4 count, HIV RNA plasma levels, serum phosphorus; serum creatinine (prior to initiation and as clinically indicated during therapy), urine glucose and urine protein (in patients at risk for renal impairment or who experienced renal impairment while taking adefovir), hepatic function tests, bone density (patients with a history of bone fracture or have risk factors for bone loss); fever, skin reactions, and/or hypersensitivity reactions; testing for HBV is recommended prior to the initiation of antiretroviral therapy; weight (children). If used as therapy replacement in virologically suppressed patients meeting criteria, additional HIV-1 RNA and regimen tolerability monitoring is recommended to assess potential virologic failure or rebound.

Patients with HIV and HBV coinfection should be monitored for several months following tenofovir discontinuation.

<2% (Limited to important or life-threatening): Abnormal dreams, anxiety, cholecystitis, cholelithiasis, diarrhea, dizziness, drowsiness, fatigue, glomerulonephritis (membranous and mesangioproliferative), hypersensitivity reaction, immune reconstitution syndrome, increased serum triglycerides ( ≥500 mg/dL), nausea, nephrolithiasis, nephrotic syndrome, vomiting, weight gain


Warnings/Precautions


Concerns related to adverse effects:

- Cardiac effects: In healthy subjects, supratherapeutic dosages of rilpivirine (75 mg once daily and 300 mg once daily) have been shown to prolong the QTc interval of the electrocardiogram; use caution when coadministering with drugs with a known risk of torsades de pointes. Canadian labeling also recommends using with caution in patients predisposed to proarrhythmic conditions (eg, clinically significant bradycardia, congenital prolongation of the QTc interval, acute myocardial ischemia, hypokalemia, heart failure).

- Decreased bone mineral density: In clinical trials, tenofovir has been associated with decreases in bone mineral density in HIV-1 infected adults and increases in bone metabolism markers. Serum parathyroid hormone and 1,25 vitamin D levels were also higher. Decreases in bone mineral density have also been observed in clinical trials of HIV-1 infected pediatric patients. Observations in chronic hepatitis B infected pediatric patients (aged 12 to 18 years) were similar. In all pediatric clinical trials, skeletal growth (height) appears unaffected. Consider monitoring of bone density in adult and pediatric patients with a history of pathologic fractures or with other risk factors for bone loss or osteoporosis. Consider calcium and vitamin D supplementation for all patients; effect of supplementation has not been studied but may be beneficial. Long-term bone health and fracture risk unknown. If abnormalities are suspected, expert assessment is recommended.

- Depressive disorders: May cause depression, depressed mood, dysphoria, major depression, mood changes, negative thoughts, suicide attempts, or suicidal ideation; if symptoms are noted, patients should be advised to seek professional intervention immediately; reevaluate risk versus benefit of continued combination therapy.

- Fat redistribution: May cause redistribution/accumulation of fat (eg, buffalo hump, peripheral wasting facial wasting, breast enlargement, cushingoid appearance).

- Hepatotoxicity: Hepatotoxicity has been reported with rilpivirine-containing regimens. Patients with hepatitis B or C or increased baseline liver function tests may be at greater risk, although some cases have occurred in patients with no preexisting disease or hepatic disease risk factors. Evaluate liver function tests in patients with increased baseline liver function tests or with hepatitis B or C prior to treatment initiation and periodically during therapy; also consider evaluation of patients with no preexisting hepatic disease or hepatic disease risk factors.

- Hypersensitivity: Hypersensitivity and severe skin reactions have been reported, including severe rash or rash accompanied by fever, blisters, mucosal involvement, conjunctivitis, facial edema, angioedema, hepatitis or eosinophilia, or drug reaction with eosinophilia and systemic symptoms (DRESS) with regimens containing rilpivirine. Some skin reactions were accompanied by constitutional symptoms (eg, fever); other skin reactions were associated with organ dysfunction (eg, hepatic serum biochemistry elevations). In clinical trials, treatment-related rashes ≥Grade 2 were reported in 1% of patients. Most rashes were Grade 1 or 2 and occurred within the first 4 to 6 weeks of therapy. Monitor laboratory parameters and clinical status; discontinue if any hypersensitivity or skin rash develop.

- Immune reconstitution syndrome: Patients may develop immune reconstitution syndrome resulting in the occurrence of an inflammatory response to an indolent or residual opportunistic infection during initial HIV treatment or activation of autoimmune disorders (eg, Graves disease, polymyositis, Guillain-Barre syndrome) later in therapy; further evaluation and treatment may be required.

- Lactic acidosis/hepatomegaly: [US Boxed Warning]: Lactic acidosis and severe hepatomegaly with steatosis have been reported with nucleoside analogues (eg, tenofovir), including fatal cases; use with caution in patients with risk factors for liver disease (risk may be increased with female gender, obesity or prolonged nucleoside exposure) and suspend treatment in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or hepatotoxicity (transaminase elevation may/may not accompany hepatomegaly and steatosis). Some cases of hepatotoxicity have occurred in patients with no hepatic disease prior to treatment.

- Osteomalacia and renal dysfunction: May cause osteomalacia with proximal renal tubulopathy. Bone pain, extremity pain, fractures, arthralgias, weakness, and muscle pain have been reported. In patients at risk for renal dysfunction, persistent or worsening bone or muscle symptoms should be evaluated for hypophosphatemia and osteomalacia.

- Pancreatitis: Pancreatitis has been reported with combination regimens that included tenofovir disoproxil fumarate; use with caution in patients with a prior history or risk factors for pancreatitis. Discontinue if pancreatitis is suspected.

- Renal toxicity: May cause renal toxicity (acute renal failure and/or Fanconi syndrome); avoid use with concurrent or recent nephrotoxic therapy (including high dose or multiple NSAID use). Acute renal failure has occurred in HIV-infected patients with risk factors for renal impairment who were on a stable tenofovir regimen to which a high dose or multiple NSAID therapy was added. Consider alternatives to NSAIDS in patients taking tenofovir and at risk for renal impairment. Calculate estimated creatinine clearance prior to initiation of therapy and monitor renal function (including recalculation of creatinine clearance and serum phosphorus) during therapy. In patients at risk for renal dysfunction, including patients who have experienced renal events while taking adefovir, assess serum phosphorus, urine glucose, and urine protein prior to and periodically during treatment. Use with caution in patients with low body weight (HHS [adult] 2015), or concurrent medications which increase tenofovir levels. IDSA guidelines recommend discontinuing tenofovir (and substituting with alternative antiretroviral therapy) in HIV-infected patients who develop a decline in GFR (a >25% decrease in GFR from baseline and to a level of <60 mL/minute/1.73 m2) during use, particularly in presence of proximal tubular dysfunction (eg, euglycemic glycosuria, increased urinary phosphorus excretion and hypophosphatemia, proteinuria [new onset or worsening]) (IDSA [Lucas 2014]).

Disease-related concerns:

- Chronic hepatitis B: [US Boxed Warning]: Safety and efficacy during coinfection of HIV and HBV have not been established; acute, severe exacerbations of HBV have been reported following discontinuation of antiretroviral therapy. Not indicated for treatment of chronic hepatitis B. All patients with HIV should be tested for HBV prior to initiation of treatment. Use caution in patients with known or suspected hepatitis B or C infection (monitoring of liver function is recommended); monitor hepatic function closely for several months following discontinuation. If appropriate, initiation of HBV therapy may be needed.

- Renal impairment: Product is a fixed-dose combination and is not appropriate for use in patients with renal impairment (CrCl <50 mL/minute).

Concurrent drug therapy issues:

- Concurrent therapy: Avoid concurrent use with adefovir or lamivudine-containing products or other emtricitabine-, rilpivirine-, and/or tenofovir-containing products.

- Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Other warnings/precautions:

- Appropriate use: Patients with increased HIV-1 viral loads (HIV-1 RNA >100,000 copies/mL) or CD4+ cell counts <200 cells/mm3 at treatment initiation are more likely to develop treatment failure (Cohen 2011; HHS [adult] 2015; Molina 2011). Therefore, rilpivirine-based regimens should not be used in adolescent and adult HIV-1 patients with a pre-ART CD4 count <200 cells/mm3 and/or HIV RNA >100,000 copies/mL (HHS [adult] 2015). Rilpivirine resistance patterns are very similar to those of etravirine (including cross resistance with single substitutions at K101P, Y181I, and Y181V) (Azijn 2010). When used to replace an antiretroviral treatment regimen in virologically-suppressed patients currently on a stable regimen, patients must have no history of virologic failure; prior to regimen replacement, must have been suppressed for at least 6 months; must be currently on their first or second antiretroviral regimen, and have no history of resistance to emtricitabine, rilpivirine, or tenofovir.

- Monitoring: If used as therapy replacement in virologically suppressed patients meeting criteria, additional HIV-1 RNA and regimen tolerability monitoring is recommended to assess potential virologic failure or rebound.


Pregnancy Risk Factor

B


Pregnancy Considerations

Animal reproduction studies have not been conducted with this combination. Refer to individual monographs.

The HHS Perinatal HIV Guidelines consider emtricitabine in combination with rilpivirine and tenofovir to be an alternative NNRTI regimen for use in antiretroviral-naive pregnant women with a pre-treatment HIV RNA ≤100,000 copies/mL or CD4 cell count ≥200 cells/mm3 (HHS [perinatal] 2016).


Actions


Pharmacology

Non-nucleoside, nucleoside, and nucleotide reverse transcriptase inhibitor combination; rilpivirine binds to reverse transcriptase and does not require intracellular phosphorylation for antiviral activity; emtricitabine is a cytosine analogue while tenofovir disoproxil fumarate (TDF) is an analog of adenosine 5-monophosphate. Each drug interferes with HIV viral RNA dependent DNA polymerase activities resulting in inhibition of viral replication.


Patient and Family Education


Patient Education

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

- Patient may experience headache, nausea, vomiting, insomnia, diarrhea, dizziness, abdominal pain, skin discoloration, nightmares, or loss of strength and energy. Have patient report immediately to prescriber signs of too much lactic acid in the blood (lactic acidosis; fast breathing, fast heartbeat, abnormal heartbeat, vomiting, drowsiness, shortness of breath, feeling very tired or weak, severe dizziness, feeling cold, or muscle pain or cramps), signs of liver problems (dark urine, feeling tired, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or yellow skin or eyes), signs of kidney problems (urinary retention, blood in urine, change in amount of urine passed, weight gain), signs of depression (suicidal ideation, anxiety, emotional instability, illogical thinking), burning or numbness feeling, shortness of breath, bone pain, muscle pain, painful extremities, change in body fat, severe skin irritation, mouth sores, dysphagia, severe eye irritation, or signs of infection (HCAHPS).

- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
