Precision BioSciences Expands Clinical Trial for Hepatitis B Cure

Precision BioSciences Expands Clinical Trial for Hepatitis B

Precision BioSciences, Inc. (NASDAQ: DTIL), a pioneering clinical-stage gene editing company based in Durham, North Carolina, has made significant strides in the treatment of chronic hepatitis B with its PBGENE-HBV program. The company recently announced the receipt of Clinical Trial Application (CTA) approval in Hong Kong, which allows the expansion of their ongoing ELIMINATE-B Phase I trial focused on PBGENE-HBV. This innovative gene editing program aims to produce curative outcomes for patients suffering from chronic hepatitis B by targeting and eliminating cccDNA, the fundamental source of the virus.

Clinical Development Strategy

Dr. Murray Abramson, Senior Vice President and Head of Clinical Development at Precision BioSciences, expressed enthusiasm about this comprehensive approach, stating, “This expansion signifies our commitment to accessing a diverse patient population suffering from chronic hepatitis B. The approval in Hong Kong not only complements our existing site in Moldova but also positions us in a strategic, high-caliber clinical environment.” The developing procedures in Hong Kong reflect a larger goal: to construct a robust regulatory and clinical operations network across crucial global markets.

Potential Impact and Advancements

With more than 400,000 cases of chronic hepatitis B reported in Hong Kong alone, the implications of this research extend far and wide. Dr. MF Yuen from the University of Hong Kong noted the pressing need for innovative therapies, highlighting how patients commonly develop severe complications like liver cancer despite current therapy options. PBGENE-HBV could fundamentally shift this narrative. By dismantling the cccDNA replication mechanism at its source, the therapy has the potential to offer not just a decrease in viral effects but an actual resolution of the virus from the body.

The PBGENE-HBV Mechanism

At its core, the PBGENE-HBV program utilizes the advanced ARCUS® gene editing platform. This technology specializes in precise genome alterations, creating a tailored approach that aims to eradicate cccDNA while simultaneously inactivating integrated HBV DNA. The process involves delivering an ARCUS nuclease-encoding mRNA directly to liver cells using lipid nanoparticles, effectively targeting the HBV genome and promoting functional cures for those afflicted.

Future Perspectives and Regulatory Pathways

As Precision BioSciences continues to navigate this complex landscape, its future efforts are geared toward a U.S. Investigational New Drug (IND) application, anticipated by 2025. The insights gained from the expanded trial sites will be integral in shaping subsequent phases of the product's development. The company plans to keep stakeholders informed on any regulatory advances and patient recruitment initiatives as they unfold.

Understanding Hepatitis B

Hepatitis B remains a leading cause of serious health complications worldwide. It affects approximately 300 million individuals globally and is responsible for significant morbidity and death due to associated conditions like cirrhosis and liver cancer. Current treatments primarily focus on viral suppression but fall short of addressing the persistent cccDNA that sustains the infection. PBGENE-HBV represents a crucial development toward a curative solution.

The Promise of PBGENE-HBV

By directly attacking the root cause of chronic hepatitis B, PBGENE-HBV aims to transform patient outcomes significantly. The ARCUS® platform's state-of-the-art technology offers new hope for individuals suffering from this persistent virus, possibly leading to lasting cures. This advancement aligns with Precision BioSciences’ overarching mission to improve lives through innovative gene editing.
