- FDA Accelerated Approval: Gilead Sciences' Hepcludex has received accelerated approval from the FDA, becoming the first treatment for chronic hepatitis delta virus infection in the U.S., addressing a long-standing gap in care for approximately 40,000 to 80,000 patients, which is expected to significantly enhance their quality of life.
- Clinical Trial Data Support: The FDA's decision was heavily informed by data from the MYR301 multi-center Phase 3 clinical trial, which demonstrated that the percentage of participants with completely undetectable viral levels increased from 20% at week 48 to 50% by week 144, confirming the drug's efficacy over time.
- Positive Market Reaction: Following the FDA approval, Gilead's stock price surged nearly 3%, poised for its best day in about three months, reflecting strong market anticipation for the new therapy and a recovery in investor confidence, with a 29% increase in stock price over the past year.
- Global Market Presence: While newly approved in the U.S., the 2 mg dose of Hepcludex has already been available in the European Economic Area and other global markets, indicating Gilead's strategic positioning and commitment to addressing chronic liver disease treatment worldwide.

New Findings on Livdelzi in PBC Treatment
- Significant ALP Normalization: In the ASSURE study, 83% of participants achieved ALP normalization at 12 months, and 74% maintained this at 24 months, demonstrating Livdelzi's long-term efficacy in treating PBC patients, potentially enhancing their quality of life.
- Improvement in Liver Stiffness: An exploratory analysis showed that 85% of participants who achieved biochemical response at 12 months maintained or improved liver stiffness over three years, indicating that Livdelzi not only lowers ALP but also enhances liver health, boosting treatment confidence.
- Good Safety Profile: Livdelzi showed no treatment discontinuations due to adverse events over two years of follow-up, with no new safety signals observed, indicating its good tolerability in high-risk PBC patients and supporting broader application.
- Clear Treatment Goals: ALP normalization is recognized as a key treatment goal in PBC, and the findings from Livdelzi's studies provide strong support for its use in PBC patients, potentially driving its wider clinical adoption.
