Antibody-Mediated Therapy of HIV-1 Infection

Objective

Antibodies are destined to neutralize pathogens and can prevent and fight infectious diseases. Over the last years, advances in single B cell cloning resulted in the isolation of highly potent and broad HIV-1 neutralizing antibodies (bNAbs) that have been shown to prevent SHIV infection in non-human primates (NHPs). Recently, we have demonstrated that a combination of bNAbs can suppress HIV-1 replication in humanized mice, reducing viremia to undetectable levels. Moreover, bNAb therapy of SHIV-infected NHPs induced a rapid decline in viremia, followed by a prolonged control due to the long half-life of the antibodies. While these results strongly encourage the clinical evaluation of bNAbs in HIV-1 therapy, it is of critical importance to understand how the therapeutic potential of antibodies can be harnessed in the most effective way. Therefore, we aim to: I.) Identify exceptionally potent HIV-1 neutralizing antibodies that will be a crucial component of immunotherapy. By establishing novel methods for single-cell sorting and high-throughput sequencing we want to identify bNAbs targeting novel epitopes. II.) Prevent HIV-1 escape applying rationally designed treatment strategies targeting conserved functional sites for HIV-1 entry. III.) Evaluate immune markers and function in relation to bNAb administration in humans. Being at the forefront of one of the first clinical trials studying an HIV-1-directed bNAb, we will have the unique opportunity to investigate the interplay of antibody therapy and the host immune system. This proposal aims to strongly advance the field of HIV-1 antibody therapy and therefore enable the introduction of a new therapeutic modality for HIV-1, and will gain insights for antibody-mediated therapy in other infectious diseases.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
