bNAb targeting gp120 on HIV-1 virus envelope

Summary

The crystal structure of VRC01 in complex with the HIV-1 gp120 core has demonstrated that this broadly neutralizing antibody, which targets the CD4 binding site (CD4bs), partially mimics the interaction between gp120 and its primary receptor, CD4. The VRC-01-gp120 interaction has a trimeric viral envelope spike that acts as an aid to gain deeper insights into the antibody’s neutralization mechanism and to identify viral determinants associated with resistance to VRC01-mediated neutralization. The half-life of VRC-01 is estimated to be ~15-20 days with a volume of distribution (Vd) of 3-5 L and a clearance (Cl) of ~0.2–0.3 mL/hr/kg. VRC-01 follows first order of kinetics at 5-30 mg/kg.

Manufacturing

VRC01 is a monoclonal antibody, and its production involves several key steps: 1. Gene Cloning and Vector Construction: The genes encoding the heavy and light chains of VRC01 are cloned and inserted into suitable expression vectors optimized for antibody production in host cells. 2. Expression Systems: Recombinant VRC01 is expressed in various systems, including human embryonic kidney (HEK) cell lines, plant-based systems (Nicotiana benthamiana or tabacum), and yeast (Pichia pastoris), depending on the desired yield and glycosylation pattern. 3. Protein Purification via affinity chromatography

Specific analytical instrument required for characterization of formulation

HPLC, mass spectrometry, spectrophotometers, and sterility tests.

More details

Background: Antibodies help the body fight infection. VRC01LS is an antibody directed against HIV virus. HIV attacks the immune system. In animals, VRC01LS inactivated many types of HIV viruses. Researchers want to see if it does this in people. Objectives: To see if VRC01LS is safe and well-tolerated in people. To see what level of VRC01LS is maintained in people and if they develop an immune response to it. Eligibility: Healthy people ages 18 to 50 Design: Participants will be screened in protocol number VRC 500 (NIH 11-I-0164) with medical history, physical exam, and blood and urine tests. The study will last 24 to 48 weeks. Visits will last 2 to 8 hours. Participants will get VRC01LS through either: * A needle in an arm vein or * A small needle placed into the fatty tissue un

More details

This is the first clinical trial of the VRC-HIVMAB060-00-AB (VRC01) monoclonal antibody. VRC01 is a broadly neutralizing antibody directed against HIV. This is a dose-escalation study to examine safety, tolerability, dose and pharmacokinetics of VRC01. The hypothesis is that VRC01 will be safe for administration to HIV-1 infected adults by the intravenous (IV) and subcutaneous (SC) routes and will not elicit hypersensitivity reactions. Samples will be collected to learn if VRC01 is detectable in mucosal secretions and blood of participants and how long VRC01 can be detected in the blood after it is given. Between 15 and 25 HIV-1 infected adults, ages 18-70 years will be enrolled. There are 4 dose escalation groups for IV administration; the doses are 1 mg/kg, 5 mg/kg, 20 mg/kg and 40 mg/k

Purpose

R. (2011). Mechanism of neutralization by the broadly neutralizing HIV-1 monoclonal antibody VRC01. Journal of virology85(17), 8954–8967. https://doi.org/10.1128/JVI.00754-11

The structure of VRC01 in complex with the HIV-1 gp120 core reveals that this broadly neutralizing CD4 binding site (CD4bs) antibody partially mimics the interaction of the primary virus receptor, CD4, with gp120. Here, we extended the investigation of the VRC01-gp120 core interaction to the biologically relevant viral spike to better understand the mechanism of VRC01-mediated neutralization and to define viral elements associated with neutralization resistance. In contrast to the interaction of CD4 or the CD4bs monoclonal antibody (MAb) b12 with the HIV-1 envelope glycoprotein (Env), occlusion of the VRC01 epitope by quaternary constraints was not a major factor limiting neutralization. Mutagenesis studies indicated that VRC01 contacts within the gp120 loop D, the CD4 binding loop, and the V5 region were necessary for optimal VRC01 neutralization, as suggested by the crystal structure. In contrast to interactions with the soluble gp120 monomer, VRC01 interaction with the native viral spike did not occur in a CD4-like manner; VRC01 did not induce gp120 shedding from the Env spike or enhance gp41 membrane proximal external region (MPER)-directed antibody binding to the Env spike. Finally, VRC01 did not display significant reactivity with human antigens, boding well for potential in vivo applications. The data indicate that VRC01 interacts with gp120 in the context of the functional spike in a manner distinct from that of CD4. It achieves potent neutralization by precisely targeting the CD4bs without requiring alterations of Env spike configuration and by avoiding steric constraints imposed by the quaternary structure of the functional Env spike.

Background: Whether a broadly neutralizing antibody (bnAb) can be used to prevent human immunodeficiency virus type 1 (HIV-1) acquisition is unclear.

Methods: We enrolled at-risk cisgender men and transgender persons in the Americas and Europe in the HVTN 704/HPTN 085 trial and at-risk women in sub-Saharan Africa in the HVTN 703/HPTN 081 trial. Participants were randomly assigned to receive, every 8 weeks, infusions of a bnAb (VRC01) at a dose of either 10 or 30 mg per kilogram (low-dose group and high-dose group, respectively) or placebo, for 10 infusions in total. HIV-1 testing was performed every 4 weeks. The VRC01 80% inhibitory concentration (IC80) of acquired isolates was measured with the TZM-bl assay.

Results: Adverse events were similar in number and severity among the treatment groups within each trial. Among the 2699 participants in HVTN 704/HPTN 085, HIV-1 infection occurred in 32 in the low-dose group, 28 in the high-dose group, and 38 in the placebo group. Among the 1924 participants in HVTN 703/HPTN 081, infection occurred in 28 in the low-dose group, 19 in the high-dose group, and 29 in the placebo group. The incidence of HIV-1 infection per 100 person-years in HVTN 704/HPTN 085 was 2.35 in the pooled VRC01 groups and 2.98 in the placebo group (estimated prevention efficacy, 26.6%; 95% confidence interval [CI], -11.7 to 51.8; P = 0.15), and the incidence per 100 person-years in HVTN 703/HPTN 081 was 2.49 in the pooled VRC01 groups and 3.10 in the placebo group (estimated prevention efficacy, 8.8%; 95% CI, -45.1 to 42.6; P = 0.70). In prespecified analyses pooling data across the trials, the incidence of infection with VRC01-sensitive isolates (IC80 <1 μg per milliliter) per 100 person-years was 0.20 among VRC01 recipients and 0.86 among placebo recipients (estimated prevention efficacy, 75.4%; 95% CI, 45.5 to 88.9). The prevention efficacy against sensitive isolates was similar for each VRC01 dose and trial; VRC01 did not prevent acquisition of other HIV-1 isolates.

Conclusions: VRC01 did not prevent overall HIV-1 acquisition more effectively than placebo, but analyses of VRC01-sensitive HIV-1 isolates provided proof-of-concept that bnAb prophylaxis can be effective.

Access principles

Collaborate for development

Consider on a case by case basis, collaborating on developing long acting products with potential significant public health impact, especially for low- and middle-income countries (LMICs), utilising the referred to long-acting technology

Not provided

Share technical information for match-making assessment

Provide necessary technical information to a potential partner, under confidentiality agreement, to enable preliminary assessment of whether specific medicines of public health importance in LMICs might be compatible with the referred to long-acting technology to achieve a public health benefit

Not provided

Work with MPP to expand access in LMICs

In the event that a product using the referred to long-acting technology is successfully developed, the technology IP holder(s) will work with the Medicines Patent Pool towards putting in place the most appropriate strategy for timely and affordable access in low and middle-income countries, including through licensing
