A Dual-guide RNA Treatment for HIV
Excision BioTherapeutics’ lead program, EBT-101, is an in vivo CRISPR-based therapeutic candidate designed to excise human immunodeficiency virus (HIV) pro-viral DNA from HIV-infected cells. EBT-101 is being developed as a potential curative treatment for patients with chronic HIV and is rapidly advancing toward clinical trials.

EBT-101’s Editing Strategy

Featuring Two gRNAs Targeting Three Sites Within the HIV Genome
EBT-101 utilizes an adeno-associated virus (AAV) to deliver a one-time treatment intended to functionally eradicate HIV infections. The investigational program employs CRISPR-Cas9 and two guide RNAs which target three sites within the HIV genome, thereby excising large portions of the HIV genome and minimizing potential viral escape.
Preclinical Development
In preclinical studies, EBT-101 demonstrated the ability to excise HIV pro-viral DNA in multiple cell lines such as human primary cells and multiple animal models, including non-human primates.

Clinical Trials
On September 15, 2021, the U.S. Food and Drug Administration (FDA) accepted the Investigational New Drug (IND) application for EBT-101, enabling the program to commence a first-in-human Phase 1/2 clinical trial to evaluate the safety, tolerability, and efficacy of EBT-101 in individuals with HIV.
