Darunavir

1 INDICATIONS AND USAGE Darunavir, co-administered with ritonavir (darunavir/ritonavir), in combination with other antiretroviral agents, is indicated for the treatment of human immunodeficiency virus (HIV-1) infection in adult and pediatric patients 3 years of age and older [see Use in Specific Populations ( 8.4 ) and Clinical Studies ( 14 )]. Darunavir is a human immunodeficiency virus (HIV-1) protease inhibitor indicated for the treatment of HIV-1 infection in adult and pediatric patients 3 years of age and older. Darunavir must be co-administered with ritonavir (darunavir/ritonavir) and with other antiretroviral agents. ( 1 )

2 DOSAGE AND ADMINISTRATION Testing: In treatment-experienced patients, treatment history genotypic and/or phenotypic testing is recommended prior to initiation of therapy with darunavir/ritonavir to assess drug susceptibility of the HIV-1 virus ( 2.1 , 12.4 ) Monitor serum liver chemistry tests before and during therapy with darunavir/ritonavir. ( 2.1 , 2.2 , 5.2 ) Treatment-naïve adult patients and treatment-experienced adult patients with no darunavir resistance associated substitutions: 800 mg (one 800 mg tablet) taken with ritonavir 100 mg once daily and with food. ( 2.3 ) Treatment-experienced adult patients with at least one darunavir resistance associated substitution: 600 mg (one 600 mg tablet) taken with ritonavir 100 mg twice daily and with food. ( 2.3 ) Pregnant patients: 600 mg (one 600 mg tablet) taken with ritonavir 100 mg twice daily and with food. ( 2.4 ) Pediatric patients (3 to less than 18 years of age and weighing at least 10 kg): dosage of darunavir and ritonavir is based on body weight and should not exceed the adult dose. Darunavir should be taken with ritonavir and with food. ( 2.5 ) Darunavir/ritonavir is not recommended for use in patients with severe hepatic impairment. ( 2.6 ) 2.1 Testing Prior to Initiation of Darunavir/ritonavir In treatment-experienced patients, treatment history, genotypic and/or phenotypic testing is recommended to assess drug susceptibility of the HIV-1 virus [see Microbiology ( 12.4 )]. Refer to Dosage and Administration ( 2.3 ), ( 2.4 ) and ( 2.5 ) for dosing recommendations. Appropriate laboratory testing such as serum liver biochemistries should be conducted prior to initiating therapy with darunavir/ritonavir [see Warnings and Precautions ( 5.2 )]. 2.2 Monitoring During Treatment with Darunavir/ritonavir Patients with underlying chronic hepatitis, cirrhosis or in patients who have pre-treatment elevations of transaminases should be monitored for elevation in serum liver biochemistries, especially during the first several months of darunavir/ritonavir treatment [see Warnings and Precautions ( 5.2 )]. 2.3 Recommended Dosage in Adult Patients Darunavir must be co-administered with ritonavir to exert its therapeutic effect. Failure to correctly co-administer darunavir with ritonavir will result in plasma levels of darunavir that will be insufficient to achieve the desired antiviral effect and will alter some drug interactions. Patients who have difficulty swallowing darunavir tablets can use the 100 mg per mL darunavir oral suspension. Treatment-Naïve Adult Patients The recommended oral dose of darunavir is 800 mg (one 800 mg tablet or 8 mL of the oral suspension) taken with ritonavir 100 mg (one 100 mg tablet or capsule or 1.25 mL of a 80 mg per mL ritonavir oral solution) once daily and with food. An 8 mL darunavir dose should be taken as two 4 mL administrations with the included oral dosing syringe. Treatment-Experienced Adult Patients The recommended oral dosage for treatment-experienced adult patients is summarized in Table 1. Baseline genotypic testing is recommended for dose selection. However, when genotypic testing is not feasible, darunavir 600 mg taken with ritonavir 100 mg twice daily is recommended. Table 1 Recommended Darunavir/ritonavir Dosage in Treatment-Experienced Adult Patients a V11I, V32I, L33F, I47V, I50V, I54L, I54M, T74P, L76V, I84V and L89V b An 8 mL darunavir dose should be taken as two 4 mL administrations with the included oral dosing syringe Baseline Resistance Formulation and Recommended Dosing Darunavir tablets with ritonavir tablets or capsule Darunavir oral suspension (100 mg/mL) with ritonavir oral solution (80 mg/mL) With no darunavir resistance associated substitutions a One 800 mg darunavir tablet with one 100 mg ritonavir tablet/capsule, taken once daily with food 8 mL b darunavir oral suspension with 1.25 mL ritonavir oral solution, taken once daily with food With at least one darunavir resistance associated substitutions a , or with no baseline resistance information One 600 mg darunavir tablet with one 100 mg ritonavir tablet/capsule, taken twice daily with food 6 mL darunavir oral suspension with 1.25 mL ritonavir oral solution, taken twice daily with food 2.4 Recommended Dosage During Pregnancy The recommended dosage in pregnant patients is darunavir 600 mg taken with ritonavir 100 mg twice daily with food. Darunavir 800 mg taken with ritonavir 100 mg once daily should only be considered in certain pregnant patients who are already on a stable darunavir 800 mg with ritonavir 100 mg once daily regimen prior to pregnancy, are virologically suppressed (HIV-1 RNA less than 50 copies per mL) and in whom a change to twice daily darunavir 600 mg with ritonavir 100 mg may compromise tolerability or compliance. 2.5 Recommended Dosage in Pediatric Patients (age 3 to less than 18 years) Healthcare professionals should pay special attention to accurate dose selection of darunavir, transcription of the medication order, dispensing information and dosing instruction to minimize risk for medication errors, overdose and underdose. Prescribers should select the appropriate dose of darunavir/ritonavir for each individual child based on body weight (kg) and should not exceed the recommended dose for adults. Before prescribing darunavir, children weighing greater than or equal to 15 kg should be assessed for the ability to swallow tablets. If a child is unable to reliably swallow a tablet, the use of darunavir oral suspension should be considered. The recommended dose of darunavir/ritonavir for pediatric patients (3 to less than 18 years of age and weighing at least 10 kg is based on body weight (see Tables 2, 3, 4 and 5) and should not exceed the recommended adult dose. Darunavir should be taken with ritonavir and with food. The recommendations for the darunavir/ritonavir dosage regimens were based on pediatric clinical trial data and population pharmacokinetic modeling and simulation [see Use in Specific Populations ( 8.4 ) and Clinical Pharmacology ( 12.3 )].

Treatment Naïve-Adults: TMC114-C211 The safety assessment is based on all safety data from the Phase 3 trial TMC114-C211 comparing darunavir/ritonavir 800/100 mg once daily versus lopinavir/ritonavir 800/200 mg per day in 689 antiretroviral treatment-naïve HIV-1-infected adult subjects. The total mean exposure for subjects in the darunavir/ritonavir 800/100 mg once daily arm and in the lopinavir/ritonavir 800/200 mg per day arm was 162.5 and 153.5 weeks, respectively. The majority of the adverse drug reactions (ADRs) reported during treatment with darunavir/ritonavir 800/100 mg once daily were mild in severity. The most common clinical ADRs to darunavir/ritonavir 800/100 mg once daily (greater than or equal to 5%) of at least moderate intensity (greater than or equal to Grade 2) were diarrhea, headache, abdominal pain and rash. 2.3% of subjects in the darunavir/ritonavir arm discontinued treatment due to ADRs. ADRs to darunavir/ritonavir 800/100 mg once daily of at least moderate intensity (greater than or equal to Grade 2) in antiretroviral treatment-naïve HIV-1-infected adult subjects are presented in Table 6 and subsequent text below the table.

Patients Co-Infected with Hepatitis B and/or Hepatitis C Virus In subjects co-infected with hepatitis B or C virus receiving darunavir/ritonavir, the incidence of adverse events and clinical chemistry abnormalities was not higher than in subjects receiving darunavir/ritonavir who were not co-infected, except for increased hepatic enzymes [see Warnings and Precautions ( 5.2 )] . The pharmacokinetic exposure in co-infected subjects was comparable to that in subjects without co-infection. Clinical Trials Experience: Pediatric Patients Darunavir/ritonavir has been studied in combination with other antiretroviral agents in 3 Phase 2 trials. TMC114-C212, in which 80 antiretroviral treatment-experienced HIV-1-infected pediatric subjects 6 to less than 18 years of age and weighing at least 20 kg were included, TMC114-C228, in which 21 antiretroviral treatment-experienced HIV-1-infected pediatric subjects 3 to less than 6 years of age and weighing at least 10 kg were included and TMC114-C230 in which 12 antiretroviral treatment-naïve HIV-1 infected pediatric patients aged from 12 to less than 18 years and weighing at least 40 kg were included. The TMC114-C212 and C228 trials evaluated darunavir/ritonavir twice daily dosing and the TMC114-C230 trial evaluated darunavir/ritonavir once daily dosing [see Use in Specific Populations ( 8.4 ) and Clinical Studies ( 14.4 )] . Frequency, type and severity of ADRs in pediatric subjects were comparable to those observed in adults. TMC114-C212 Clinical ADRs to darunavir/ritonavir (all grades, greater than or equal to 3%), were vomiting (13%), diarrhea (11%), abdominal pain (10%), headache (9%), rash (5%), nausea (4%) and fatigue (3%). Grade 3 or 4 laboratory abnormalities were ALT increased (Grade 3: 3%; Grade 4: 1%), AST increased (Grade 3: 1%), pancreatic amylase increased (Grade 3: 4%, Grade 4: 1%), pancreatic lipase increased (Grade 3: 1%), total cholesterol increased (Grade 3: 1%) and LDL increased (Grade 3: 3%). TMC114-C228 Clinical ADRs to darunavir/ritonavir (all grades, greater than or equal to 5%), were diarrhea (24%), vomiting (19%), rash (19%), abdominal pain (5%) and anorexia (5%).
