Assembly Biosciences' ABI-4334 Shows Potent Antiviral Activity in Phase 1b Chronic Hepatitis B Trial
- Assembly Biosciences reported positive Phase 1b results for ABI-4334, a next-generation capsid assembly modulator, showing potent antiviral activity against chronic hepatitis B virus infection.
- The 400 mg dose cohort demonstrated mean HBV DNA reductions of 3.2 log10 IU/mL over 28 days, consistent with the 150 mg cohort's 2.9 log10 IU/mL reduction.
- ABI-4334 maintained a favorable safety profile with once-daily oral dosing supported by pharmacokinetic data across both dose levels.
- The trial completion triggers Gilead Sciences' option to license ABI-4334 for further development under their existing collaboration agreement.
