Consult the Summary of Product Characteristics before prescribing.
GENVOYA® elvitegravir 150mg/cobicistat 150mg/emtricitabine 200mg/ tenofovir alafenamide 10mg film coated tablets.
Indication: Treatment of HIV-1 infection in adults & adolescents (aged 12 years & older weighing at least 35 kg) without any known mutations associated with resistance to the integrase inhibitor class, emtricitabine or tenofovir. Dosage: Adults & adolescents (aged ≥ 12 years, weighing at least 35 kg): One tablet, once daily, orally & whole with food. Children (< 12 years or weighing < 35kg): Safety & efficacy has not been established. Elderly: No dose adjustment is required. Renal: No dose adjustment is required in adult or adolescent patients (aged ≥ 12 years, weighing at least 35 kg) with estimated creatinine clearance (CrCl) ≥ 30 mL/min. In patients with CrCl < 30 mL/min: not recommended. Should be discontinued in patients whose CrCl declines to < 30 mL/min during treatment. Hepatic: Mild/moderate hepatic impairment: no dose adjustment required. Severe hepatic impairment: not recommended. Contraindications: Hypersensitivity to the active substances or to any excipients. Coadministration with alfuzosin, amiodarone, quinidine, carbamazepine, phenobarbital, phenytoin, rifampicin, dihydroergotamine, ergometrine, ergotamine, cisapride, St. John’s wort, lovastatin, simvastatin, pimozide, sildenafil for treatment of pulmonary arterial hypertension & oral midazolam & triazolam. Warnings & Precautions: Should not be co- administered with other antiretroviral products. Safety & efficacy in HCV co- infection has not been established. Tenofovir alafenamide is active against HBV. Co-infected HIV/HBV patients should be closely monitored for at least several months following discontinuation for symptoms of severe acute exacerbations of hepatitis. Should not be administered concomitantly with medicines containing tenofovir alafenamide, tenofovir disoproxil, lamivudine or adefovir dipivoxil for treatment of HBV infection. Patients with galactose intolerance, Lapp lactase deficiency & glucose-galactose malabsorption should not take Genvoya. Women of childbearing potential should use either a hormonal contraceptive containing at least 30 μg ethinylestradiol & norgestimate as the progestagen or an alternative reliable method of contraception. Risks of mitochondrial dysfunction, immune reactivation syndrome, opportunistic infections, osteonecrosis with nucleoside analogues & CART therapy. Interactions: Co-administration with medicines that induce/inhibit CYP3A may affect the exposure of elvitegravir by decreasing its plasma concentrations leading to a reduced therapeutic effect of Genvoya. Cobicistat is an inhibitor of CYP3A & is a CYP3A substrate. Medicines highly dependent on CYP3A metabolism & have high first pass metabolism are most susceptible to large increases in exposure when co-administered with cobicistat. Medicines that inhibit CYP3A may decrease the clearance of cobicistat, resulting in increased plasma concentrations of cobicistat. Co- administration with medicines that are substrates of P-gp, BCRP, OATP1B1 & OATP1B3 may result in increased plasma concentrations of these products. Medicines that decrease renal function may increase concentrations of emtricitabine. Pregnancy & lactation: Should be used during pregnancy only if the potential benefit justifies the potential risk to the foetus. It should not be used during breast-feeding. Side effects: Refer to SPC for full information regarding side effects. Very common (≥1/10): Nausea. Common (≥1/100 to <1/10): Headache, dizziness, diarrhoea, vomiting, abdominal pain, flatulence, abnormal dreams, rash & fatigue. Uncommon (≥1/1000 to <1/100): anaemia, depression,
dyspepsia, angioedema & puritus. Legal Category: POM. Pack: Bottle of 30 film-coated tablets. Price: UK NHS List Price - £879.51; Éire/Ireland – POA.

• For the entire study population, BMD increased significantly overall– Increases were greater for those on preswitch TDF (p<0.001)
• Spine BMD increased significantly for without preswitch TDF use (p=0.03)
Safety Summary• Upper respiratory tract infection (15%), diarrhoea (13%), and arthralgia (14%)
were the most common adverse events (AEs)• AEs, grades, and frequencies were generally similar in participants with baseline
CrCl < vs ≥50 mL/min• No participants discontinued study drug for AEs between Weeks 96 and 144

• No new participants discontinued study drug for renal AEs after Week 96• There were no cases of proximal renal tubulopathy or Fanconi syndrome through Week 144• 2 participants with medical history of TDF-associated Fanconi syndrome remained
on treatment with Genvoya with stable eGFR, and significant reductions in total and tubular proteinuria
• Of those participants with clinically significant albuminuria (UACR ≥3.4 mg/mmol) at baseline, 47% had resolution by Week 144
• Median (quartile [Q] 1, Q3) changes from baseline at Week 144 with preswitch TDF use:– eGFRCKD-EPI,sCr: 3.6 (-5.7, 11.4) mL/min/1.73 m2
– eGFRCKD-EPI,cysC: 3.7 (-3.4, 15.3) mL/min/1.73 m2
Conclusions• This is the first study of a single-tablet antiretroviral regimen in participants
with CrCl of 30–69 mL/min
• Through Week 144, HIV-infected adults with mild to moderate renal impairment who switched to Genvoya had high rates of virologic suppression, stable renal function, and statistically significant improvements in proteinuria and BMD (hip and spine), with benefits most notable for those with preswitch TDF use
• These long-term data support switching from TDF-containing regimens to Genvoya in patients with mild to moderate renal impairment (CrCl 30–69 mL/min)
