TLR7 agonist 2 is found to be rapidly cleared in conjunction with our target profile. Both Cmax and AUC increase less than dose proportionally between 0.3 and 3 mg/kg and more than dose-proportionally between 3 and 10 mg/kg. TLR7 agonist 2 can induce an antiviral interferon stimulated gene (ISG) response without inducing an IFNα response at a low dose. TLR7 agonist 2 also induces a 2.7 log decrease in serum HBV viral load from 0.3 mg/kg, and a maximum 3.1 log decrease is observed for doses between 1 and 5 mg/kg[1].
