Hepatitis B: what the trials found

Treatment with Tenofovir Disoproxil Fumarate (TDF) has been evaluated for HBsAg loss. In a study comparing TDF plus Peg-IFN against Peg-IFN alone or TDF alone, the combination of TDF and Peg-IFN showed a significantly higher percentage of participants achieving HBsAg loss at week 72 compared to both monotherapies (p < 0.001) 20. In another trial, TDF was shown to result in lower rates of HBsAg loss compared to a control group (0.236 vs 0; p=0.022) 5.

Telbivudine demonstrated high rates of viral suppression, with approximately 91% to 99% of participants achieving HBV DNA < 300 Copies/mL at week 52 15.

Various vaccines have been evaluated for efficacy and safety. Engerix-B and its variants (Engerix-B Kinder) were shown to elicit anti-HBs titers above 12 IU/L following boosters 7 and demonstrated manageable local and general symptoms in clinical settings 18. Other established vaccines include TWINRIX, Fendrix, and Infanrix hexa [11, 12, 16]. Sci-B-Vac™ showed a high percentage of subjects achieving HBs antibody titers ≥100 mIU/ml across multiple timepoints 9.

Hepatitis B Immune Globulin (HBIG) administration did not show statistically significant differences in blood glucose levels 19.

Recent results — preliminary, needs further review

  • AB-729 is currently under investigation in a Phase 2 trial 1.
  • VIR-2218 was evaluated in a Phase 2 trial regarding sustained serum HBsAg loss; however, the reported proportions were low or zero across study arms 2.
  • GS-2829 was assessed in a Phase 1 trial; results showed high rates of treatment-emergent adverse events and laboratory abnormalities, with varying levels of T-cell response increases 3.
  • A candidate vaccine adjuvanted with the AS03 system was evaluated for safety; reported administration site and systemic adverse events were generally short-lived (1-4 days) 4.

For the clinician treating this condition

  • TDF in combination with Peg-IFN is significantly more effective at inducing HBsAg loss compared to either monotherapy 20.
  • Telbivudine shows high efficacy for achieving viral suppression (HBV DNA < 300 Copies/mL) by week 52 15.
  • Multiple vaccine formulations, including Engerix-B and Infanrix hexa, are established for inducing anti-HBs antibodies and providing protection [7, 11, 22].
