Safety and Efficacy of Dolutegravir/Lamivudine (DTG/3TC) in Therapy-naive Human Immunodeficiency Virus-1 (HIV-1) Infected Adolescents

• Status: Active, not recruiting

Summary

First-line antiretroviral regimens are highly efficacious and generally well tolerated. However, as these regimens need to be taken life-long, there is growing concern about long-term toxicities associated with these regimens. Thus, there is great interest from participants and clinicians in unique regimens that might avoid such toxicities by minimizing the number of antiretrovirals without sacrificing long-term antiviral efficacy. DTG plus 3TC is a novel, well-tolerated first-line regimen for HIV-infected treatment- naive participants, limiting the risk of many common adverse reactions associated with other antiretroviral drugs. Thus, this study is designed to evaluate the efficacy and safety of DTG/3TC as a FDC, in ART-naive HIV-1-infected adolescents, who weigh at least 25 kilograms (kg). The study will consists of Screening Phase (up to 28 days prior to the first dose of drug) followed by Treatment Phase (up to 48 weeks). Participants who successfully complete 48 weeks of therapy and who continue to receive benefit from DTG/3TC FDC may enter a 96 weeks study Extension Phase. Study participants who have successfully completed both the Treatment Phase through 48 weeks and the Extension Phase through 144 weeks and continue to receive benefit from this two-drug regimen will continue to receive DTG/3TC FDC in a Continuation Phase (after Week 144) until: DTG and 3TC are both locally approved for use as part of a dual regimen and the single entities of DTG and 3TC are available to participants (e.g. through public health services), or the DTG/3TC FDC tablet, if required by local regulations, is locally approved and available (e.g. commercially or through public health services), or the participant no longer derives clinical benefit or the participant meets a protocol-defined reason for discontinuation. All participants will receive the FDC of DTG/3TC (50/300 milligrams) for once daily. Approximately 30 participants will be enrolled in the study.
