Drug class/category

bNAb targeting gp120 on HIV-1 virus envelope

Summary

VRC07-523LS (VRC-HIVMAB075-00-AB; TMB-380) is a broadly neutralizing antibody (bNAb) engineered to target the CD4 binding site on HIV’s envelope protein gp120. It is a modified version of VRC01, with an LS mutation that extends its half-life, allowing less frequent dosing. Administered via IV, IM, SC, it has shown safety and tolerability in clinical trials. TaiMed develops TMB-380 as part of the antibody-only TMB-365/TMB-380 regimen at 4,800 mg IV every 8 weeks. VRC07-523LS is an engineered VRC01-class antibody with the LS Fc modification, neutralising 96% of strains at IC50 below 50 microgram/mL and 92% below 1 microgram/mL, with 5- to 8-fold greater potency than VRC01.

More details

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: Ad

Background: Human immunodeficiency virus (HIV) infection is a serious disease. There is no cure or vaccine to prevent infection. Using antibodies might be a good way to treat or prevent HIV. Antibodies are naturally made by the body to fight germs. Researchers want to test if two antibodies made artificially in a lab can help to prevent HIV infection.

More details

This study is testing a lab-made antibody called ePGT121v1-LS that targets a specific part of HIV. Researchers will give it by vein (IV) and under the skin (SC), both on its own and together with two other antibodies, VRC07-523LS and PGDM1400LS, which target different parts of the virus. They will assess safety and side effects, determine the right dose, study how the body processes the drug (pharmacokinetics or PK), and measure how well it neutralizes HIV in the blood (serum neutralizing activity). The expectation is that ePGT121v1-LS, whether given alone or with PGDM1400LS and VRC07-523LS, by IV or SC, will be safe in generally healthy adults and that the antibodies will not interfere with each other when used together. Approximately 83 volunteers in overall good health and without HIV-

TMB-365 is a monoclonal antibody that binds to the CD4 receptor. TMB-380, aka VRC07-523LS is a monoclonal antibody that binds to HIV. Both interfere with HIV entry. This study is designed to test the combination of the antibodies as maintenance therapy in HIV infected suppressed individuals discontinuing oral cART for 48 weeks. Researchers will compare TMB-365/TMB-380 given IV every 8 weeks to continuation of daily oral cART to see if TMB-365/TMB-380 can also maintain viral suppression. Participants will: 1. Receive TMB-365/TMB-380 infusion or take oral cART as scheduled for 48 weeks 2. Visit the clinic as schedule for checkups and tests

Publication Safety and pharmacokinetics of escalating doses of neutralising monoclonal antibody CAP256V2LS administered with and without VRC07-523LS in HIV-negative women in South Africa (CAPRISA 012B): a phase 1, dose-escalation, randomised controlled trial Background: Young women in sub-Saharan Africa continue to bear a high burden of HIV infection. Combination anti-HIV monoclonal antibodies are a potential HIV prevention technology that could overcome adherence challenges of daily oral pre-exposure prophylaxis. In this phase 1 clinical trial we aimed to determine the safety and pharmacokinetic profile of the broadly neutralising monoclonal antibody CAP256V2LS. Methods: CAPRISA 012B, a first-in-human dose-escalation phase 1 trial evaluated the safety, pharmacokinetics, and neutralisation activity of CAP256V2LS alone and in combination with VRC07-523LS in young HIV-negative women in Durban, South Africa. Groups 1 and 2 were open label with CAP256V2LS administered at 5 mg/kg and 10 mg/kg intravenously and 5 mg/kg, 10 mg/kg, and 20 mg/kg subcutaneously. In group 3, participants were randomly allocated to receive a combination of CAP256V2LS and VRC07-523LS at 10 mg/kg and 20 mg/kg subcutaneously comixed with ENHANZE, a recombinant human hyaluronidase. Once safety was established in the first three participants, dose escalation took place sequentially following review of safety data. Primary endpoints were the proportion of participants with mild, moderate, and severe reactogenicity or adverse events, graded as per the Division of AIDS toxicity grading. The trial is registered on the Pan African Clinical Trial Registry, PACTR202003767867253, and is recruiting. Findings: From July 13, 2020, to Jan 13, 2021, 42 HIV-negative women, aged 18-45 years, were enrolled. All 42 participants, eight with intravenous and 34 with subcutaneous administration, completed the trial. There were no serious adverse events or dose-limiting toxicities. Most commonly reported symptoms following intravenous administration were headaches in seven (88%) and nausea in four (50%) participants. Commonly reported symptoms following subcutaneous administration were headache in 31 (91%), chills in 25 (74%), and malaise or fatigue in 19 (56%) participants. Adverse events included transient lymphocytopenia in eight (19%), proteinuria in nine (21%), elevated aspartate aminotransferase in ten (24%), and alanine aminotransferase in five (12%) participants. Interpretation: CAP256V2LS administered alone and in combination with VRC07-523LS was safe with favourable pharmacokinetics and neutralisation activity, supporting further assessment in larger clinical studies.
Publication Cervicovaginal microbiome diversity was not associated with mucosal pharmacokinetics of systemically delivered HIV broadly neutralizing antibodies Broadly neutralizing antibodies (bNAbs) are a promising HIV prevention strategy due to their potent antiviral activity and potential for long-acting protection. While the vaginal microbiome can influence mucosal immunity and the efficacy of topical interventions, its effect on the pharmacokinetics of systemically administered bNAbs remains unclear. Forty-two women were included in a retrospective analysis of the CAPRISA 012B clinical trial evaluating passive immunization for HIV prevention. Vaginal microbiota were profiled using 16 S rRNA gene sequencing and classified into three community state types (CSTs): CST I (Lactobacillus crispatus-dominated), CST III (Lactobacillus iners-dominated), and CST IV (diverse, non-Lactobacillus-dominated). Mucosal concentrations of CAP256V2LS were measured from Soft-cup® cervicovaginal fluid using the Meso Scale Discovery (MSD) platform with electrochemiluminescence (ECL) detection. Longitudinal analyses assessed CST stability, transitions, and associations with mucosal antibody pharmacokinetics. Lactobacillus-dominated CSTs were most frequent (CST I, 5.3%; CST III, 57.9%), whereas BV-associated CST IV subtypes were less common (CST IV-A, 2.6%; CST IV-B, 34.2%). Lactobacillus-dominated communities were generally stable, while high-diversity CST IV communities were more dynamic, with transitions toward Lactobacillus-dominated states observed over time. Despite these microbial shifts, mucosal bNAb kinetic patterns appeared broadly similar across CSTs. Within the limits of this exploratory analysis, we did not observe clear evidence of an association between CST composition and the timing or magnitude of mucosal bNAb accumulation. These observations were descriptive and not derived from inferential statistical or pharmacokinetic modelling analyses. In this exploratory sub-analysis, cervicovaginal microbiome composition was not clearly associated with differences in mucosal concentrations of systemically administered bNAbs. These findings suggest that systemic bNAb delivery may achieve measurable genital tract exposure across diverse vaginal microbial communities; however, larger studies incorporating inferential pharmacokinetic and immunological analyses are needed to confirm these observations and exclude subtle microbiome-associated effects.

Publication Assessing the safety and pharmacokinetics of the anti-HIV monoclonal antibody CAP256V2LS alone and in combination with VRC07-523LS and PGT121 in South African women: study protocol for the first-in-human CAPRISA 012B phase I clinical trial Introduction: New HIV prevention strategies are urgently required. The discovery of broadly neutralising antibodies (bNAbs) has provided the opportunity to evaluate passive immunisation as a potential prevention strategy and facilitate vaccine development. Since 2014, several bNAbs have been isolated from a clade C-infected South African donor, CAPRISA 256. One particular bNAb, CAP256-VRC26.25, was found to be extremely potent, with good coverage against clade C viruses, the dominant HIV clade in sub-Saharan Africa. Challenge studies in non-human primates demonstrated that this antibody was fully protective even at extremely low doses. This bNAb was subsequently structurally engineered and the clinical variant is now referred to as CAP256V2LS.Methods and analysis: CAPRISA 012B is the second of three trials in the CAPRISA 012 bNAb trial programme. It is a first-in-human, phase I study to assess the safety and pharmacokinetics of CAP256V2LS. The study is divided into four groups. Group 1 is a dose escalation of CAP256V2LS administered intravenously to HIV-negative and HIV-positive women. Group 2 is a dose escalation of CAP256V2LS administered subcutaneously (SC), with and without the dispersing agent recombinant human hyaluronidase (rHuPH20) as single or repeat doses in HIV-negative women. Groups 3 and 4 are randomised placebo controlled to assess two (CAP256V2LS+VRC07-523LS; CAP256V2LS+PGT121) and three (CAP256V2LS+VRC07-523LS+PGT121) bNAb combinations administered SC to HIV-negative women. Safety will be assessed by the frequency of reactogenicity and adverse events related to the study product. Pharmacokinetic disposition of CAP256V2LS alone and in combination with VRC07-523LS and PGT121 will be assessed via dose subgroups and route of administration.Ethics and dissemination: The University of KwaZulu-Natal Biomedical Research Ethics Committee (BREC) and the South African Health Products Regulatory Authority (SAHPRA) have granted regulatory approval (trial reference numbers: BREC00000857/2019 and SAHPRA 20200123). Trial results will be disseminated through conference presentations, peer-reviewed publications and the clinical trial registry.

The goal of this clinical trial is to learn if subcutaneous ePGT121v1-LS and VRC07-523-LS added to standard antiretroviral therapy (ART) is safe and helps improve HIV viral suppression in infants living with HIV in Mozambique and Cameroon. The study will also learn how the body processes ePGT121v1-LS and VRC07-523-LS and whether caregivers and health workers find this treatment approach acceptable. The main questions it aims to answer are: * Are ePGT121v1-LS and and VRC07-523-LS safe and well tolerated in infants living with HIV? * Does adding ePGT121v1-LS and VRC07-523-LS to standard ART increase the number of infants who achieve HIV viral suppression by week 48? * How long does it take participants receiving ePGT121v1-LS and VRC07-523-LS to achieve viral suppression compared with stand

Abstract

Background: Effective, long-acting prevention approaches are needed to reduce human immunodeficiency virus (HIV) incidence. We evaluated the safety and pharmacokinetics of VRC07-523LS and PGT121 administered subcutaneously alone and in combination as passive immunization for young women in South Africa.

Methods: CAPRISA 012A was a randomized, double-blinded, placebo-controlled, dose-escalation phase 1 trial. We enrolled 45 HIV-negative women into 9 groups and assessed safety, tolerability, pharmacokinetics, neutralization activity, and antidrug antibody levels. Pharmacokinetic modeling was conducted to predict steady-state concentrations for 12- and 24-weekly dosing intervals.

Results: VRC07-523LS and PGT121, administered subcutaneously, were safe and well tolerated. Most common reactogenicity events were injection site tenderness and headaches. Nine product-related adverse events were mild and transient. Median VRC07-523LS concentrations after 20 mg/kg doses were 9.65 μg/mL and 3.86 μg/mL at 16 and 24 weeks. The median week 8 concentration after the 10 mg/kg PGT121 dose was 8.26 μg/mL. Modeling of PGT121 at 20 mg/kg showed median concentrations of 1.37 μg/mL and 0.22 μg/mL at 16 and 24 weeks. Half-lives of VRC07-523LS and PGT121 were 29 and 20 days. Both antibodies retained neutralizing activity postadministration and no antidrug antibodies were detected.

Conclusions: Subcutaneous administration of VRC07-523LS in combination with optimized versions of PGT121 or other antibodies should be further assessed for HIV prevention.

Abstract


Background:


Human monoclonal antibodies that potently and broadly neutralize HIV-1 (bnMAbs) are under development to prevent and treat HIV-1 infection. We performed a phase 1 clinical trial to determine the safety, tolerability, and pharmacokinetic profile of the bnMAb VRC07–523LS, an engineered variant of VRC01 that targets the CD4 binding-site of the HIV-1 Env protein.

Methods:


This phase 1, open-label, dose-escalation clinical trial was done at the National Institutes of Health Clinical Center in Bethesda, MD, USA. Individuals were recruited from the greater Washington, DC, area by IRB-approved written and electronic media. We enrolled healthy, HIV-1-negative adults aged 18–50 years. Inclusion criteria were good general health, measured through clinical laboratory tests, medical history, and physical examination. Participants self-selected into one of seven open groups during enrollment without randomization. Four groups received a single intravenous dose of 1, 5, 20, or 40 mg/kg of VRC07–523LS, and one group received a single 5 mg/kg subcutaneous dose. Two groups received three doses of either 20 mg/kg intravenous VRC07–523LS, or 5 mg/kg subcutaneous VRC07–523LS at 12-week intervals. The primary outcome was the safety and tolerability of VRC07–523LS, assessed by dose, route, and number of administrations. This study is registered with ClinicalTrials.govNCT03015181.

Findings:


Between Feb 21, 2017, and September 13, 2017, we enrolled 26 participants, including 11 (42%) men and 15 (58%) women. Two (8%) participants withdrew from the study early: one participant in group 1 enrolled in the study but never received VRC07–523LS, and one participant in group 6 chose to withdraw after a single administration. One (4%) participant in group 7 received only one of the three scheduled administrations. 17 participants received intravenous administrations and 8 participants received subcutaneous administrations. Local and systemic reactogenicity were mild to moderate when reported. The most commonly reported symptoms following IV administration included malaise or myalgia in three participants (18%) and headache or chills in two participants (12%). Following SC administration, the most commonly reported symptoms included pain and tenderness in four participants (50%) and malaise or headache in three participants (38%). No serious adverse events or dose-limiting toxicities occurred.

Interpretations:


We found VRC07–523LS to be safe and well tolerated. These qualities make VRC07–523LS a strong and practical candidate for inclusion in HIV-1 prevention and therapeutic strategies. The results from this trial also indicate that an HIV-1 bnMAb engineered to improve pharmacokinetic properties and neutralization activity can be safe for clinical use.
