Outcomes

Primary Outcome Measures

Number of Participants With Treatment-Emergent Adverse Events (TEAEs): Healthy Volunteers
An adverse event (AE) is any untoward medical occurrence which does not necessarily have a causal relationship with this treatment. A serious AE is any AE that: results in death; is life-threatening; requires inpatient hospitalization or prolongation of an existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; or is a medically important event or reaction.Events were categorized as mild, moderate or severe. TEAEs were defined as all AEs starting or worsening after commencement of treatment with investigational product. A treatment-related TEAE was one whose relationship to treatment was noted as unlikely, possibly, or probably related.

5. Study Description

Brief Summary
Normal healthy volunteer (NHV) participants will enroll sequentially into a total of 6 escalating dose levels (6 subjects per dose level), randomized to receive a single dose of ARC-521 Injection or placebo. The maximum study duration for NHVs is approximately 21 weeks. Hepatitis B e Antigen (HBeAg)-negative participants with (CHB) will enroll sequentially into 3 dose levels (8 patients per dose level) to receive multiple doses of open label ARC-521 Injection. For each CHB participant the maximum study duration is approximately 37 weeks.
Detailed Description
Phase 1a/1b multicenter dose-escalation study of ARC-521 Injection in normal healthy volunteers and patients with CHB. Eligible participants who have signed an Ethics Committee (EC)/Institutional Review Board (IRB) approved informed consent form and have met all of the protocol eligibility criteria. Patients will undergo the following evaluations at regular intervals during the study: medical history, physical examinations, vital sign measurements (blood pressure, heart rate, respiratory rate, and temperature), weight, adverse events assessment (AEs), concomitant medications/therapies assessment, electrocardiograms (ECGs), telemetry [NHVs only], measures of hepatic fibrosis [CHBs only], blood sample collection for hematology, coagulation, chemistry, Pharmacokinetics (PK) [NHVs only], metabolic analysis [NHVs only], exploratory Pharmacodynamic (PD) measures, urinalysis, hepatitis B virus (HBV) serology, immunogenicity, Follicle Stimulating Hormone (FSH) testing (post-menopausal females) and pregnancy testing for females of childbearing potential. Clinically significant changes including AEs will be followed until resolution, until the condition stabilizes, until the event is otherwise explained, or until the patient is lost to follow-up. Prior to enrollment there is a 60 day screening period.
