What this trial studies

This open-label study aims to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of Tune-401 in adults diagnosed with Chronic Hepatitis B. The study will begin with a single-ascending dose phase to determine the appropriate dosage for further evaluation. Following this, an expansion phase will continue to monitor the drug's activity on PD parameters and gather additional safety data. Participants will be closely monitored throughout the study to ensure comprehensive data collection.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-75 who have been diagnosed with Chronic Hepatitis B and are currently on nucleos(t)ide analogue therapy.

Not a fit: Patients with liver disease of non-HBV etiology or those with significantly elevated liver enzymes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients suffering from Chronic Hepatitis B.

How similar studies have performed: Other studies have shown promise with similar approaches in treating Chronic Hepatitis B, but the specific use of Tune-401 is novel.
