ViiV Healthcare announces data demonstrating the feasibility of Dovato (dolutegravir/lamivudine) as a treatment option for rapid initiation after diagnosis in adults with HIV-1
WARNING: PATIENTS CO-INFECTED WITH HEPATITIS B VIRUS (HBV) AND HUMAN IMMUNODEFICIENCY VIRUS (HIV-1): EMERGENCE OF LAMIVUDINE-RESISTANT HBV AND EXACERBATIONS OF HBV
- All patients with HIV-1 should be tested for the presence of HBV prior to or when initiating Dovato. Emergence of lamivudine-resistant HBV variants associated with lamivudine-containing antiretroviral regimens has been reported. If Dovato is used in patients co-infected with HIV-1 and HBV, additional treatment should be considered for appropriate treatment of chronic HBV; otherwise, consider an alternative regimen.
- Severe acute exacerbations of HBV have been reported in patients who are co-infected with HIV-1 and HBV and have discontinued lamivudine, a component of Dovato. Closely monitor hepatic function in these patients and, if appropriate, initiate anti-HBV treatment
DOSAGE AND ADMINISTRATION
- Prior to or when initiating Dovato, test patients for HBV infection.
- Pregnancy Testing: Perform pregnancy testing before initiation of Dovato in individuals of childbearing potential.
- One tablet taken orally once daily with or without food.
- The dolutegravir dose (50 mg) in Dovato is insufficient when co-administered with carbamazepine or rifampin. If Dovato is co-administered with carbamazepine or rifampin, take one tablet of Dovato once daily, followed by an additional dolutegravir 50-mg tablet, approximately 12 hours from the dose of Dovato
- Prior hypersensitivity reaction to dolutegravir or lamivudine.
- Coadministration with dofetilide.
WARNINGS AND PRECAUTIONS
- Hypersensitivity reactions characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury, have been reported with dolutegravir. Discontinue Dovato immediately if signs or symptoms of hypersensitivity reactions develop, as a delay in stopping treatment may result in a life-threatening reaction.
- Hepatotoxicity has been reported in patients receiving a dolutegravir-containing regimen. Patients with underlying hepatitis B or C may be at increased risk for worsening or development of transaminase elevations with Dovato. Monitoring for hepatotoxicity is recommended.
- Embryo-fetal toxicity may occur when used at the time of conception and in early pregnancy. Avoid use of Dovato at the time of conception through the first trimester of pregnancy due to the risk of neural tube defects. Advise individuals of childbearing potential to use effective contraception.
- Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues.
- Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy.
The most common adverse reactions (all grades) observed in ≥2% (in those receiving Dovato) were headache, nausea, diarrhoea, insomnia, fatigue, and anxiety.
- Dovato is a complete regimen for the treatment of HIV-1 infection; therefore, coadministration with other antiretroviral drugs for the treatment of HIV-1 infection is not recommended.
- Refer to the full prescribing information for important drug interactions with Dovato
USE IN SPECIFIC POPULATIONS
- Pregnancy: An alternative treatment to Dovato should be considered at the time of conception through the first trimester due to the risk of neural tube defects.
- Lactation: Breastfeeding is not recommended due to the potential for HIV-1 transmission.
- Females and males of reproductive potential: Pregnancy testing and contraception are recommended in individuals of childbearing potential.
- Renal Impairment: Dovato is not recommended in patients with creatinine clearance less than 50 mL/min.
- Hepatic Impairment: Dovato is not recommended in patients with severe hepatic impairment (Child-Pugh Score C).
