Hepatitis C is a global health concern, with an estimated 58 million people chronically infected. The World Health Organization (WHO) aims to eliminate viral hepatitis as a public health threat by 2030, with effective treatment being crucial to this strategy. However, while several highly effective direct-acting antiviral (DAA) medications are available, they remain unavailable and expensive, especially in low- and middle-income (LMIC) settings such as Vietnam.
Currently, the standard course of treatment for Hepatitis C lasts 12 weeks and costs $1,300 (about 33 million VND). In Vietnam, only 50% of the treatment cost is covered by social insurance. The prolonged treatment duration and high cost can discourage patients from seeking or following up with treatment.
The VIETNARMS trial, which ran from 2018 to 2024 and enrolled 624 patients, directly compared two widely used hepatitis C treatment regimens: sofosbuvir/daclatasvir (SOF/DCV) and sofosbuvir/velpatasvir (SOF/VEL). This head-to-head comparison, the first of its kind, revealed that SOF/DCV demonstrated slightly higher cure rates compared to SOF/VEL. This finding is particularly significant for low- and middle-income countries where SOF/DCV is more readily accessible and affordable.
Beyond comparing existing treatments, the VIETNARMS trial explored innovative treatment strategies designed to enhance accessibility and affordability. The research team investigated shorter treatment durations and a response-guided approach where treatment duration is tailored to individual patient response.
The results were promising. One strategy involving a response-guided approach demonstrated comparable effectiveness to the standard 12-week treatment duration while shortening the treatment duration and halving the treatment cost. These findings provide new strategies for expanding access to treatment, particularly for vulnerable and underserved communities, and have the potential to shape treatment guidelines worldwide.
