Rhea-AI Summary

Arbutus Biopharma (Nasdaq: ABUS) announced the acceptance of five abstracts for presentation at the European Association for the Study of the Liver (EASL) Congress 2025 in Amsterdam. The presentations, scheduled for May 7-10, 2025, include significant findings on two key drug candidates:

Imdusiran: The IM-PROVE I study showed that HBsAg levels at baseline and NA discontinuation were key factors for functional cure in chronic hepatitis B patients. Subjects achieving functional cure demonstrated rapid HBV RNA decline during imdusiran treatment, with transient elevations during interferon treatment leading to further HBsAg decline.

AB-101: This oral PD-L1 inhibitor showed promising results in early trials, demonstrating safety and tolerability in both single and multiple doses. The drug exhibited dose-responsive increases in PD-L1 receptor occupancy and high liver biodistribution, with preliminary data showing receptor occupancy at doses ≥10 mg.

Rhea-AI Summary

Genevant Sciences and Arbutus Biopharma (ABUS) have initiated five international patent infringement lawsuits against Moderna across 30 countries. The legal actions target Moderna's alleged unauthorized use of their lipid nanoparticle (LNP) technology in Spikevax® and mRESVIA® products.

The lawsuits have been filed in multiple jurisdictions including Canada, Japan, Switzerland, and the Unified Patent Court (UPC). The companies are seeking monetary damages and injunctions against Moderna's products. Evidence from testing commercial Moderna samples from the U.S. and Europe indicates the presence of LNPs that fall under their patent claims.

This international enforcement expands on their ongoing U.S. proceeding in Delaware, where a jury trial is scheduled for September 2025. The LNP technology, important for mRNA medicine delivery, was developed by Arbutus and Genevant scientists and has been licensed to various third parties.
