Phase 2 Study Comparing Oral ALG-000184 With Tenofovir Disoproxil Fumarate for Untreated Adults With Chronic Hepatitis B

What this Trial Is About

Researchers are evaluating the safety and effectiveness of 48 weeks of daily oral treatment with ALG-000184 compared to tenofovir disproxil fumarate TDF in adults with chronic hepatitis B virus HBV infection. This Phase 2 randomized, double-blind, active-controlled study includes both untreated HBeAg-positive and HBeAg-negative adults. The study aims to understand how well these treatments control HBV infection and their safety profiles. Participants will receive either ALG-000184 or TDF tablets once daily for 48 weeks. After this double-blind period, all participants may continue treatment with open-label ALG-000184 for an additional 48 weeks, making a total treatment duration of 96 weeks. The study is divided into two parts, focusing separately on HBeAg-positive and HBeAg-negative subjects, with some taking part in an exploratory liver biopsy sub-study. Throughout the study, participants will undergo regular assessments including measuring HBV DNA levels to see if the virus is suppressed below a set detection limit at 48 weeks. Safety and tolerability will be monitored up to 96 weeks. Other evaluations include liver enzyme levels, viral resistance, and drug pharmacokinetics. The study involves blood tests, liver assessments, and ongoing monitoring to track treatment effects and participant health over nearly two years.
