Brief summary

Drug Farm is developing an investigational drug called DF-006, to treat chronic hepatitis B. DF-006 is a drug that attaches to a protein in the cell know as Alpha-1 kinase (ALPK1). In the liver, upon attaching to ALPK1, there is an activation of the body’s immune system that leads to the expression of many immune-related proteins known as chemokines and cytokines. These chemokines and cytokines are thought to play a role at various stages of hepatitis B virus (HBV) lifecycle, ultimately leading to reductions in viral (1) replication, (2) immunosuppressive proteins and, (3) genetic material. The study has two main aims: • To see if DF-006 is safe and well-tolerated in healthy adults. • To measure levels of DF-006, and compounds related to DF-006, in the blood over time, following multiple doses of DF-006. The study will also look at: • Whether or not ethnicity affects the levels of DF-006 in the blood. • Whether DF-006 is processed and cleared differently in people of Asian ethnicity. • If certain markers in your blood show that DF-006 is working as predicted.

Interventions

Healthy subjects in Part 1 will receive a single oral liquid dose of DF-006, starting at 3mcg, for one day. Subsequent doses will be based on safety data from prior patients and cohorts. Healthy subjects in Part 2 will receive a single oral liquid dose of DF-006 weekly for 14 days, starting at the dose determined in Part 1. Participants in Part 2 are likely to be different from participants in Part 1. A Study Safety Committee will provide safety oversight and will follow Dose Selection Guideli

Healthy subjects in Part 1 will receive a single oral liquid dose of DF-006, starting at 3mcg, for one day. Subsequent doses will be based on safety data from prior patients and cohorts. Healthy subjects in Part 2 will receive a single oral liquid dose of DF-006 weekly for 14 days, starting at the dose determined in Part 1. Participants in Part 2 are likely to be different from participants in Part 1. A Study Safety Committee will provide safety oversight and will follow Dose Selection Guidelines to determine cohort doses. Cohort progression will be based on Data Review Meetings. In Part 1, cohort progression will occur approximately every 3 weeks. In Part 2, cohort progression will occur approximately every 4 weeks. Adherence to the intervention will be monitored by direct observation of dosing.
