NIH-funded research R21 grant

Developing new therapies to eliminate chronic hepatitis B virus infection

Official title: Engineering exosomes for new gRNA/Cas therapeutics to eliminate HBV infection

Funded at East Tennessee State University · NIH-11004677 · Data updated 2026-11-12

This study is exploring a new way to help people with chronic hepatitis B by using special tiny particles to deliver a gene-editing tool that could completely get rid of the virus, offering hope for a cure instead of just managing the infection.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals diagnosed with chronic hepatitis B virus infection who have not responded adequately to existing antiviral treatments.

Less likely to help

Patients who are not infected with hepatitis B virus or those who have acute infections may not benefit from this research.

What this research studies

This research focuses on creating innovative therapies using engineered exosomes to deliver CRISPR/Cas technology aimed at eliminating chronic hepatitis B virus (HBV) infection. Current treatments can manage the virus but do not eradicate it, leaving patients at risk for long-term complications. By utilizing advanced gene-editing techniques, the study aims to specifically target and remove the viral DNA from infected cells, potentially leading to a complete cure. The approach emphasizes safety and efficacy by using non-viral delivery systems to minimize risks associated with traditional methods.

Why it matters

Potential benefit: If successful, this research could provide a groundbreaking cure for chronic hepatitis B virus infection, significantly improving patient outcomes.

How similar studies have gone: While the use of CRISPR/Cas technology is a relatively novel approach in this context, there have been successful applications of similar gene-editing strategies in other viral infections.
