    Dosage

    Adults and paediatric patients aged 6 years and older, weighing at least 25 kg: One tablet to be taken once daily with food.
    If the patient misses a dose of Gendevra within 18 hours of the time it is usually taken, the patient should take Gendevra with food as soon as possible and resume the normal dosing schedule. If a patient misses a dose of Gendevra by more than 18 hours, the patient should not take the missed dose and simply resume the usual dosing schedule.
    If the patient vomits within 1 hour of taking Gendevra another tablet should be taken.
    Elderly: No dose adjustment of Gendevra is required in elderly patients.
    Renal impairment: No dose adjustment of Gendevra is required in adults or adolescents (aged at least 12 years and of at least 35 kg body weight) with estimated creatinine clearance (CrCl) ≥ 30 mL/min.
    No data are available to make dose recommendations in children aged less than 12 years with renal impairment.
    Gendevra should not be initiated in patients with estimated CrCl < 30 mL/min as there are limited data available regarding the use of Gendevra in this population.
    Gendevra should be discontinued in patients with estimated CrCl that declines below 30 mL/min during treatment.
    Hepatic impairment: No dose adjustment of Gendevra is required in patients with mild (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment. Gendevra has not been studied in patients with severe hepatic impairment (Child-Pugh Class C); therefore, Gendevra is not recommended for use in patients with severe hepatic impairment.
    Paediatric population: The safety and efficacy of Gendevra in children younger than 6 years of age, or weighing < 25 kg, have not yet been established. No data are available.
    Method of administration: Gendevra should be taken orally, once daily with food. The film-coated tablet should not be chewed or crushed. For patients who are unable to swallow the tablet whole, the tablet may be split in half and both halves taken one after the other, ensuring that the full dose is taken.


    Indications

    Treatment of human immunodeficiency virus-1 (HIV-1) infection without any known mutations associated with resistance to the integrase inhibitor class, emtricitabine or tenofovir as follows:

    • In children aged from 6 years and with body weight at least 25 kg for whom alternative regimens are unsuitable due to toxicities.


    Contra-Indications

    Hypersensitivity to the active substances or to any of the excipients.
    Co-administration with the following medicinal products due to the potential for serious or life-threatening adverse reactions or loss of virologic response and possible resistance to this drug:
    Alpha 1-adrenoreceptor antagonists: alfuzosin.
    Antiarrhythmics: amiodarone, quinidine.
    Ergot derivatives: dihydroergotamine, ergometrine, ergotamine.
    Gastrointestinal motility agents: cisapride.
    HMG Co-A reductase inhibitors: lovastatin, simvastatin.
    Neuroleptics/antipsychotics: pimozide, lurasidone.
    PDE-5 inhibitors: sildenafil for the treatment of pulmonary arterial hypertension.
    Sedatives/hypnotics: orally administered midazolam, triazolam.
    Anticonvulsants: carbamazepine, phenobarbital, phenytoin.

    Herbal products: St. John’s wort (Hypericum perforatum).
    Co-administration with dabigatran etexilate, a P-glycoprotein (P-gp) substrate.


    Special Precautions

    Patients co-infected with HIV and hepatitis B or C virus: Patients with chronic hepatitis B or C treated with antiretroviral therapy are at an increased risk for
    severe and potentially fatal hepatic adverse reactions.
    The safety and efficacy of Gendevra in patients co-infected with HIV-1 and hepatitis C virus (HCV) have not been established.
    Tenofovir alafenamide is active against hepatitis B virus (HBV). Discontinuation of Gendevra therapy in patients co-infected with HIV and HBV may be associated with severe acute exacerbations of hepatitis. Patients co-infected with HIV and HBV who discontinue Gendevra should be closely monitored with both clinical and laboratory follow-up for at least several months after stopping
    treatment.
    Liver disease: The safety and efficacy of This drug in patients with significant underlying liver disorders have not been established. Patients with pre-existing liver dysfunction, including chronic active hepatitis, have an increased frequency of liver function abnormalities during combination antiretroviral therapy (CART) and should be monitored according to standard practice. If there is evidence of worsening liver disease in such patients, interruption or discontinuation of treatment must be considered.
    Weight and metabolic parameters: An increase in weight and in levels of blood lipids and glucose may occur during antiretroviral therapy. Such changes may in part be linked to disease control and life style. For lipids, there is in some cases evidence for a treatment effect, while for weight gain there is no strong evidence relating this to any particular treatment. For monitoring of blood lipids and glucose reference is made to established HIV treatment guidelines. Lipid disorders should be managed as clinically appropriate.
    Immune Reactivation Syndrome: In HIV infected patients treated with CART, including with emtricitabine, immune reactivation syndrome has been reported. In HIV infected patients with severe immune deficiency at the time of institution of CART, an inflammatory reaction to asymptomatic or residual opportunistic pathogens may arise and cause serious clinical conditions, or aggravation of symptoms. Typically, such reactions have been observed within the first few weeks or months of initiation of CART. Relevant examples include cytomegalovirus retinitis, generalised and/or focal mycobacterial infections, and Pneumocystis jirovecii pneumonia. Any inflammatory symptoms should be evaluated and treatment instituted when necessary.
    Autoimmune disorders (such as Graves’ disease and autoimmune hepatitis) have also been reported to occur in the setting of immune reactivation; however, the reported time to onset is more variable, and these events can occur many months after initiation of treatment.
    Opportunistic infections: Patients receiving this drug or any other antiretroviral therapy may continue to develop opportunistic infections and other complications of HIV infection, and therefore should remain under close clinical observation by physicians experienced in the treatment of patients with HIV associated diseases.
    Osteonecrosis: Although the aetiology is considered to be multifactorial (including corticosteroid use, alcohol consumption, severe immunosuppression, higher body mass index), cases of osteonecrosis have been reported particularly in patients with advanced HIV disease and/or long-term exposure to CART. Patients should be advised to seek medical advice if they experience joint aches and pain, joint stiffness or difficulty in movement.
    Nephrotoxicity: A potential risk of nephrotoxicity resulting from chronic exposure to low levels of tenofovir due to dosing with tenofovir alafenamide cannot be excluded.
    Co-administration of other medicinal products: Some medicinal products should not be co-administered with this drug.
    Contraception requirements: Female patients of childbearing potential should use either a hormonal contraceptive containing at least 30 μg ethinylestradiol and containing norgestimate as the progestagen or should use an alternative reliable method of contraception. The effect of co-administration of this drug with oral contraceptives containing progestagens other than norgestimate is not known and, therefore, should be avoided.
    Excipients: This drug contains lactose monohydrate. Consequently, patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency, or glucose-galactose malabsorption should not take this medicinal product.
    See prescribing information for full details.


    Side Effects

    Very common: Nausea.
    Common: Abnormal dreams, headache, dizziness, diarrhoea, vomiting, abdominal pain, flatulence, rash, fatigue.
    See prescribing information for full details.


    Drug interactions

    Gendevra should not be co-administered with other antiretroviral medicinal products. Therefore, information regarding drug-drug interactions with other antiretroviral products (including protease inhibitors [PIs] and non-nucleoside reverse transcriptase inhibitors [NNRTIs]) is not provided. Interaction studies have only been performed in adults.
    Gendevra should not be administered concomitantly with medicinal products containing tenofovir alafenamide, tenofovir disoproxil, lamivudine or adefovir dipivoxil used for the treatment of HBV infection.
    Concomitant use contraindicated: Co-administration of Gendevra and some medicinal products that are primarily metabolised by CYP3A may result in increased plasma concentrations of these products, which are associated with the potential for serious or life-threatening adverse reactions such as peripheral vasospasm or ischaemia (e.g., dihydroergotamine, ergotamine, ergometrine), or myopathy, including rhabdomyolysis (e.g., simvastatin, lovastatin), or prolonged or increased sedation or respiratory depression (e.g., orally administered midazolam or triazolam). Co-administration of Gendevra and other medicinal products primarily metabolised by CYP3A such as amiodarone, quinidine, cisapride, pimozide, lurasidone, alfuzosin and sildenafil for pulmonary arterial hypertension is contraindicated.
    Co-administration of Gendevra and some medicinal products that induce CYP3A such as St. John’s wort (Hypericum perforatum), rifampicin, carbamazepine, phenobarbital, and phenytoin may result in significantly decreased cobicistat and elvitegravir plasma concentrations, which may result in loss of therapeutic effect and development of resistance.
    See prescribing information for full details.


    Pregnancy and Lactation

    Pregnancy: There are no adequate and well-controlled studies of this drug or its components in pregnant women. Gendevra should be used during pregnancy only if the potential benefit justifies the potential risk to the foetus.
    LactationThere is insufficient information on the effects of elvitegravir, cobicistat, emtricitabine and tenofovir in newborns/infants. Therefore, Gendevra should not be used during breast-feeding.
    In order to avoid transmission of HIV to the infant it is recommended that HIV infected women do not breast-feed their infants under any circumstances.
    See prescribing information for full details.                       


    Overdose

    If overdose occurs the patient must be monitored for evidence of toxicity. Treatment of overdose with Gendevra consists of general supportive measures including monitoring of vital signs as well as observation of the clinical status of the patient.
    As elvitegravir and cobicistat are highly bound to plasma proteins, it is unlikely that they would be significantly removed by haemodialysis or peritoneal dialysis. Emtricitabine can be removed by haemodialysis, which removes approximately 30% of the emtricitabine dose over a 3 hour dialysis period starting within 1.5 hours of emtricitabine dosing. Tenofovir is efficiently removed by haemodialysis with an extraction coefficient of approximately 54%. It is not known whether emtricitabine or tenofovir can be removed by peritoneal dialysis.
