Background:
The human body uses antibodies as one way to help fight infection. VRC01LS and VRC07-523LS are antibodies directed against the HIV virus. Researchers want to see if they are safe and well tolerated. In Part A of the study, the researchers studied VRC01LS. Part A of the study was completed in 2017. In Part B, the researchers studied VRC07-523LS. Depending on which antibody received, researchers studied the amount of VRC01LS or VRC07-523LS in the body and how it changes over time. They evaluated the effect of antibodies on CD4+ (Cluster of Differentiation 4) lymphocyte count and HIV viral load, and checked to see if people who get VRC01LS or VRC07-523LS develop an immune response to it.
Objective:
To see if VRC01LS and VRC07-523LS are safe and well tolerated.
Eligibility:
Adults ages 18-70 who are HIV infected but otherwise healthy.
Design:
Participants received the study drug one time by IV infusion. A needle guided a thin tube into a vein. The study drug mixed with salt water was dripped into the vein over about 30 minutes.
Participants were monitored for 30 minutes after the infusion.
Blood samples were taken at the following times:
* Once before the infusion
* 5 times in the 4 hours after the infusion
* 1 time 24 hours after infusion. Some participants may have had 3 optional blood draws in the time period between 4 and 24 hours.
For 3 days after the infusion, participants recorded their temperature and reactogenicity symptoms in a diary.
There were a total of 23 study visits over 48 weeks. Ten visits were in the first 4 weeks. At all visits, participants answered health questions and gave blood samples.

Broadly neutralizing antibodies (bNAbs) may provide an alternative to standard antiretroviral treatment (ART) for controlling HIV-1 replication and may have immunotherapeutic effects against HIV-1 reservoirs. We conducted a prospective clinical trial with two HIV-1 bNAbs (VRC01LS and 10-1074) in children (n= 25) who had previously initiated small-molecule ART treatment before 7 days of age and who continued treatment for at least 96 weeks. Both bNAbs were dosed intravenously every 4 weeks, overlapping with ART for at least 8 weeks and then continued for up to 24 weeks or until detectable viremia of HIV-1 RNA rose above 400 copies per milliliter in the absence of ART. Eleven (44%) children maintained HIV-1 RNA below 400 copies per milliliter through 24 weeks of bNAb-only treatment; 14 (56%) had detectable viremia above 400 copies per milliliter at a median of 4 weeks. Archived HIV-1 provirus susceptible to 10-1074, lower birth HIV-1 DNA reservoir in peripheral blood mononuclear cells, sustained viral suppression throughout early life, and combined negative qualitative HIV-1 DNA polymerase chain reaction and negative HIV-1 serology at entry were associated with maintaining suppression on bNAbs alone. This proof-of-concept study suggests that bNAbs may represent a promising treatment modality for infants and children living with HIV-1. Future studies using newer bNAb combinations with greater breadth and potency are warranted.

Background::

Broadly neutralizing monoclonal antibodies (bNAbs) suppress HIV-1 RNA and may deplete residual viral reservoirs. We evaluated the safety and pharmacokinetics (PK) of dual intravenous VRC01LS and 10-1074 in very early-treated children with HIV-1 on suppressive antiretroviral treatment (ART).

Setting::

Botswana.

Methods::

Children with HIV-1 (median age 3.1 years) on ART from <7 days old were enrolled. In phase A, 6 children received 10-1074 (30 mg/kg at day 0, 28, and 56) and 6 children received VRC01LS (30 mg/kg at day 0, 10 mg/kg at days 28 and 56) by intravenous infusion. In phase B, 6 children received the 2 bNAbs combined (with higher VRC01LS maintenance dose, 15 mg/kg) every 4 weeks for 32 weeks with PK evaluations over 8 weeks. Population PK models were developed to predict steady-state concentrations.

Results::

BNAb infusions were well tolerated. There were no infusion reactions nor any bNAb-related grade 3 or 4 events. The median (range) first dose Cmax and trough (day 28) combined from both phases were 1405 (876–1999) μg/mL and 133 (84–319) μg/mL for 10-1074 and 776 (559–846) μg/mL and 230 (158–294) μg/mL for VRC01LS. No large differences in bNAb clearances were observed when given in combination. The estimated VRC01LS half-life was shorter than in adults. Predicted steady-state troughs [median (90% prediction interval)] were 261 (95–565) and 266 (191–366) μg/mL for 10-1074 and VRC01LS, respectively, when given in combination.

Conclusions::

10-1074 and VRC01LS were safe and well-tolerated among children receiving ART. Troughs exceeded minimal targets with every 4-week administration of 10-1074 at 30 mg/kg and VRC01LS at 15 mg/kg.

Abstract:

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. All received antiretroviral prophylaxis. VRC01LS levels were compared to VRC01 levels determined in a prior cohort.

Results:

Local reactions (all grade ≤2) occurred in 67% and 20% after dose 1 and dose 2, respectively. The weight-banded dose (mean 28.8 mg/kg) of VRC01LS administered subcutaneously achieved a mean (standard deviation) plasma level of 222.3 (71.6) µg/mL by 24 hours and 44.0 (11.6) µg/mL at week 12, prior to dose 2. The preestablished target of ≥50 µg/mL was attained in 95% and 32% at weeks 8 and 12, respectively. The terminal half-life was 37–41 days. VRC01LS level after 1 dose was significantly greater (P <.002) than after a VRC01 dose (20 mg/kg). No infants acquired HIV-1.

Conclusions:

VRC01LS was well tolerated with pharmacokinetics that support further studies of more potent long-acting bNAbs as adjunct treatment with antiretrovirals to prevent infant HIV-1 transmission.
