Safety, Tolerability, and Pharmacokinetics of Long-Acting Broadly Neutralizing HIV-1 Monoclonal Antibody VRC07523LS in Newborn Infants Exposed to HIV-1.

Background: Vertical HIV-1 transmission despite antiretroviral therapy may be mitigated by use of long-acting, broadly neutralizing, monoclonal antibodies (bNAb) such as VRC07523LS. The present study was designed to determine the safety and pharmacokinetics of VRC07523LS.

Methods: VRC07523LS, 80 mg/dose, was administered subcutaneously after birth to non-breastfed (Cohort 1; N=11, enrolled in USA) and breastfed (Cohort 2; N=11, enrolled in South Africa and Zimbabwe) infants exposed to HIV-1.

Efficacy and safety of three antiretroviral therapy regimens started in pregnancy up to 50 weeks post partum: a multicentre, open-label, randomised, controlled, phase 3 trial.

Background: Drugs taken during pregnancy can affect maternal and child health outcomes, but few studies have compared the safety and virological efficacy of different antiretroviral therapy (ART) regimens. We report the primary safety outcomes from enrolment up to 50 weeks post partum and a secondary virological efficacy outcome at 50 weeks post partum of three commonly used ART regimens for HIV-1.

Methods: In this multicentre, open-label, randomised, controlled, phase 3 trial, we enrolled pregnant women aged 18 years or older with confirmed HIV-1 infection at 14-28 weeks of gestation.

Safety, Tolerability, and Pharmacokinetics of a Long-Acting Broadly Neutralizing Human Immunodeficiency Virus Type 1 (HIV-1) Monoclonal Antibody VRC01LS in HIV-1-Exposed Newborn Infants.

Background: Perinatal human immunodeficiency virus type 1 (HIV-1) continues to occur due to barriers to effective antiretroviral prevention that might be mitigated by long-acting broadly neutralizing monoclonal antibodies (bNAbs).

Methods: An extended half-life bNAb, VRC01LS, was administered subcutaneously at 80 mg/dose after birth to HIV-1-exposed, nonbreastfed (cohort 1, n = 10) and breastfed (cohort 2, n = 11) infants. Cohort 2 received a second dose (100 mg) at 12 weeks.

Efficacy and safety of dolutegravir with emtricitabine and tenofovir alafenamide fumarate or tenofovir disoproxil fumarate, and efavirenz, emtricitabine, and tenofovir disoproxil fumarate HIV antiretroviral therapy regimens started in pregnancy (IMPAACT 2010/VESTED): a multicentre, open-label, randomised, controlled, phase 3 trial.

Background: Antiretroviral therapy (ART) during pregnancy is important for both maternal health and prevention of perinatal HIV-1 transmission; however adequate data on the safety and efficacy of different ART regimens that are likely to be used by pregnant women are scarce. In this trial we compared the safety and efficacy of three antiretroviral regimens started in pregnancy: dolutegravir, emtricitabine, and tenofovir alafenamide fumarate; dolutegravir, emtricitabine, and tenofovir disoproxil fumarate; and efavirenz, emtricitabine, and tenofovir disoproxil fumarate.

Methods: This multicentre, open-label, randomised controlled, phase 3 trial was done at 22 clinical research sites in nine countries (Botswana, Brazil, India, South Africa, Tanzania, Thailand, Uganda, the USA, and Zimbabwe).

Pharmacokinetics and Safety of Zidovudine, Lamivudine, and Lopinavir/Ritonavir in HIV-infected Children With Severe Acute Malnutrition in Sub-Saharan Africa: IMPAACT Protocol P1092.

Background: Severe acute malnutrition (SAM) may alter the pharmacokinetics (PK), efficacy, and safety of antiretroviral therapy. The phase IV study, IMPAACT P1092, compared PK, safety, and tolerability of zidovudine (ZDV), lamivudine (3TC), and lopinavir/ritonavir (LPV/r) in children with and without SAM.

Materials And Methods: Children living with HIV 6 to <36 months of age with or without World Health Organization (WHO)-defined SAM received ZDV, 3TC, and LPV/r syrup for 48 weeks according to WHO weight band dosing.
