Safety and Efficacy of Dolutegravir/Lamivudine (DTG/3TC) in Therapy-naive Human Immunodeficiency Virus-1 (HIV-1) Infected Adolescents
February 13, 2024 updated by: ViiV Healthcare
An Open-label, Single Arm Study to Evaluate the Week 48 Efficacy and Safety of a Two-drug Regimen of Dolutegravir/Lamivudine (DTG/3TC) as a Fixed Dose Combination (FDC), in Antiretroviral Therapy (ART)-Naive HIV-1-infected Adolescents, ≥12 to <18 Years of Age Who Weigh at Least 25 kg
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.

Description
Inclusion Criteria:
- HIV-1 infected adolescents >=12 to <18 years of age at the time of signing the informed consent form.
- Weight >=25 kg at the time of signing the informed consent form.
- Screening plasma HIV-1 RNA between 1,000 and <=500,000 c/mL.
- Antiretroviral-naive (defined as no prior therapy with any antiretroviral agent for the treatment of HIV following a diagnosis of HIV-1 infection). Participants who received ART for prevention of mother to child transmission of HIV in the first 3 months of life are allowed. Participants who received HIV post-exposure prophylaxis (PEP) or pre-exposure prophylaxis (PrEP) in the past are allowed as long as the last PEP/PrEP dose was >6 months from HIV diagnosis or there is documented HIV seronegativity at least 2 months after the last prophylactic dose and prior to the date of HIV diagnosis.
- Male and female participants will be included. A female participant is eligible to participate if she is not pregnant (as confirmed by a negative serum human chorionic gonadotrophin [hCG] test at Screening and negative urine hCG test before Enrollment) and not lactating. Female participants who are of child bearing potential and who are engaging in sexual activity that could lead to pregnancy, must agree to use one of the birth control method from 28 days prior to the first dose of study medication, and until 4 weeks after the last dose of study medication (and completion of the follow-up visit). Condoms are recommended in addition, because their appropriate use is the only contraception method effective for preventing HIV-1 transmission. The investigator is responsible for ensuring that participants understand how to properly use these methods of contraception. All participants participating in the study should also be counselled on safer sexual practices, including the use and benefit/risk of effective barrier methods (example given [e.g.] male condom), and on the risk of HIV transmission to an uninfected partner.
- The participant's parent(s) or legal guardian or the participant is capable of giving signed informed consent.
Exclusion Criteria:
- Females who are breastfeeding or plan to become pregnant or breastfeed during the study.
- Any evidence of an active Centers for Disease Control and Prevention (CDC) Stage 3 and/or Category C or World Health Organization (WHO) Stage 4 disease, except cutaneous Kaposi's sarcoma not requiring systemic therapy and historical or current CD4 cell counts less than 200 cells per cubic millimeter (cells/mm^3) or CD4 percent <15 percent.
- Participants with severe hepatic impairment (Class C) as determined by Child-Pugh classification.
- Unstable liver disease (as defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, or persistent jaundice), cirrhosis, known biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
- Evidence of hepatitis B virus (HBV) infection based on the results of testing at Screening for HBV surface antigen (HBsAg), HBV core antibody (anti-HBc), HBV surface antibody (anti-HBs or HBsAb), and HBV Deoxyribonucleic acid (DNA) as follows: participants positive for HBsAg are excluded; participants negative for anti-HBs but positive for anti-HBc (negative HBsAg status) and positive for HBV DNA are excluded. Participant's positive for anti-HBc (negative HBsAg status) and positive for anti-HBs (past and/or current evidence) are immune to HBV and are not excluded.
- Anticipated need for any HCV therapy during the first 48 weeks of the study and for HCV therapy based on interferon or any drugs that have a potential for adverse drug: drug interactions with study treatment throughout the entire study period.
- Untreated syphilis infection (positive rapid plasma reagin [RPR] at Screening without clear documentation of treatment). Participants who are at least 24 hours post completed treatment are eligible.
- History or sensitivity to any of the study medications or their components or drugs of their class, or a history of drug or other allergy that in the opinion of the Investigator or Medical Monitor contraindicates participation.
- Ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non-invasive cutaneous squamous cell carcinoma, or cervical, anal or penile intraepithelial neoplasia; other localized malignancies require agreement between the investigator and the Study Medical Monitor for inclusion of the participant.
- Participants who in the investigator's judgment, poses a significant suicidality risk. Recent history of suicidal behavior and/or suicidal ideation may be considered as evidence of serious suicide risk.
- Treatment with an HIV-1 immunotherapeutic vaccine within 90 days of Screening.

- Any evidence of pre-existing viral resistance based on the presence of any major resistance-associated mutation in the Screening result or, if known, in any historical resistance test result.
- Any verified Grade 4 laboratory abnormality. A single repeat test is allowed during the Screening period to verify a result.
- Any acute laboratory abnormality at Screening, which, in the opinion of the Investigator, would preclude the participant's participation in the study of an investigational compound.
- ALT >=5 times the upper limit of normal (ULN) or ALT >=3 times ULN and bilirubin >=1.5 times ULN (with >35 percent direct bilirubin).
- Creatinine clearance of <50 milliliters per minute per 1.73 square meter (mL/min/1.73 m^2) using the Schwartz equation method.
