A Multiple Ascending Dose Proof of Concept Study


Title: A Phase 2, Randomized, Open-label, Ascending, Sequential Dose Group, Multiple Dose Study of the Safety, Tolerability, Pharmacokinetics and Antiviral Activity of TXL™ in HBV-infected Subjects

Condition: Infectious Disease

Interventions: TXL™; TDF (Viread)


Primary Objective: To evaluate the safety and tolerability of multiple oral (PO) doses of TXL™ at multiple ascending dose levels; to evaluate the antiviral activity of TXL™ versus Tenofovir disproxil fumarate (TDF; Viread)

Secondary Objective: To evaluate the pharmacokinetics (PK) of multiple doses of TXL™ at multiple dose levels in a fasted state
