About the DAWNING study
DAWNING is a phase IIIb,
Adult patients failing first-line therapy, with HIV-1 RNA ≥400 copies(c)/mL, were randomised (1:1, stratified by baseline plasma HIV-1 RNA and number of fully active background NRTIs) to 52 weeks of open-label treatment with DTG or LPV/RTV combined with an investigator-selected dual NRTI background, including at least one fully active NRTI.
Professional Indication(s) and Important Safety Information
Indications and Usage
TIVICAY is a human immunodeficiency virus type 1 (HIV-1) integrase strand transfer inhibitor (INSTI) indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults and
Limitations of use:
- Use of TIVICAY in INSTI-experienced patients should be guided by the number and type of baseline INSTI substitutions. The efficacy of TIVICAY 50 mg twice daily is reduced in patients with an INSTI-resistance Q148 substitution plus 2 or more additional INSTI-resistance substitutions including T66A, L74I/M, E138A/K/T, G140S/A/C, Y143R/C/H, E157Q, G163S/E/K/Q, or G193E/R
Important Safety Information
TIVICAY is contraindicated in patients:
- With previous hypersensitivity reaction to
- Receiving dofetilide (antiarrhythmic)
- Hypersensitivity reactions have been reported and were characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury. The events were reported in <1% of subjects receiving TIVICAY in phase III clinical trials
- Discontinue TIVICAY and other suspect agents immediately if signs or symptoms of hypersensitivity reactions develop, as a delay in stopping treatment may result in a life-threatening reaction. Monitor clinical status, including liver aminotransferases, and initiate appropriate therapy if
hypersensitivityreaction is suspected
Effects on Serum Liver Biochemistries in Patients with Hepatitis B or C Co-infection:
- Patients with underlying hepatitis B or C may be at increased risk for worsening or development of transaminase elevations with use of TIVICAY. In some
casesthe elevations in transaminases were consistent with immune reconstitution syndrome or hepatitis B reactivation, particularly in the setting where anti-hepatitis therapy was withdrawn
- Appropriate laboratory testing prior to initiating therapy and monitoring for hepatotoxicity during therapy with TIVICAY are recommended in patients with
underlyinghepatic disease such as hepatitis B or C
Fat Redistribution or accumulation has been observed in patients receiving antiretroviral therapy.
Immune Reconstitution Syndrome, including the occurrence of autoimmune disorders with variable time to onset, has been reported.
Adverse Reactions: The most commonly reported (≥2%) adverse reactions of moderate to severe intensity in treatment-naïve adult subjects in any one trial receiving TIVICAY in a combination regimen were insomnia (3%), fatigue (2%), and headache (2%).
- Coadministration of TIVICAY with certain inducers of UGT1A and/or CYP3A may reduce plasma concentrations of
dolutegravirand require dose adjustments of TIVICAY
- Administer TIVICAY 2 hours before or 6 hours after taking polyvalent cation-containing antacids or laxatives, sucralfate, oral supplements containing iron or calcium, or buffered medications. Alternatively, TIVICAY and supplements containing calcium or iron can be taken with food
- Consult the full Prescribing Information for TIVICAY for more information on potentially significant drug interactions, including clinical comments
Pregnancy: TIVICAY should be used during pregnancy only if the potential benefit justifies the potential risk. An Antiretroviral Pregnancy Registry has been established.
Nursing Mothers: Breastfeeding is not recommended due to the potential for HIV transmission and the potential for adverse reactions in nursing infants.
