Brief Summary

Background: A number of diseases can cause a type of lung injury called pulmonary arterial hypertension (PAH). Most people who develop PAH do not survive more than a few years. A new study drug (ZMA001) may help. ZMA001 is a monoclonal antibody. This type of drug consists of proteins, made in a facility, that are very similar to proteins in a human body. But before giving ZMA001 to people sick with PAH, researchers want to find out how the drug affects healthy people. Objective: To test a drug (ZMA001) in healthy volunteers. Eligibility: Healthy adults aged 18 to 60 years. Design: Participants will be screened. They will have a physical exam with blood tests. They will have a urine test for drug use. They will have a test of their heart function. Participants will come to the clinic for 1 inpatient visit of up to 48 hours. ZMA001 is a liquid administered through a tube attached to a needle inserted into a vein in the arm. Participants will receive this drug only once, during their inpatient stay. Some participants will receive the drug; others will receive a placebo in Cohort 1 only. A placebo is a treatment that looks just like the real drug but contains no medicine. Participants will not know which treatment they are getting in Cohort 1. Cohorts 2-4 will receive a single dose of the study drug, administered through a tube attached to a needle inserted into a vein in the arm. After a screening visit, participants will have 1 inpatient visit and up to 8 outpatient visits over 16 weeks after receiving the treatment. Blood draws and other tests will be repeated. Each outpatient visit is approximately 2 hours long. This study is the first time ZMA001 will be administered to people.

Outcome Measures

Primary Outcomes (1)

  • Safety and tolerability of ZMA001 in healthy subjects

    The number of all-cause, treatment-emergent adverse events, grade 1 and above (following CTCAE v5.0 criteria) through day 113

    day 113

Secondary Outcomes (3)

  • Determine the pharmacokinetics of ZMA001 in healthy subjects following a single, intravenous dose.

    Pre-infusion, end of infusion, 2, 4, 8, 12, 24, and 48h; Days 8, 15, 22, 29, 57, 85 and 113

  • Determine the pharmacokinetics of ZMA001 in healthy subjects following a single, intravenous dose.

    Pre-infusion, end of infusion, 2, 4, 8, 12, 24, and 48h; Days 8, 15, 22, 29, 57, 85 and 113

  • Determine the pharmacokinetics of ZMA001 in healthy subjects following a single, intravenous dose.

    Pre-infusion, end of infusion, 2, 4, 8, 12, 24, and 48h; Days 8, 15, 22, 29, 57, 85 and 113

Study Arms (2)

Placebo Cohort 1 (1.5 mg/kg/dose) only

PLACEBO COMPARATOR

Placebo for ZMA001 is supplied in a single-use 10 mL glass vial. Each vial contains 30 mg/mL of sucrose.Placebo drug is manufactured using the same ingredients as active drug (20 mM histidine-HCl buffer \[pH 5.6\], 30 mg/mL sucrose, 0.070 w/v% polysorbate 80) excluding ZMA001 antibody and is packed in the same vial.

Other: Placebo Cohort 1 (1.5 mg/kg/dose) only

ZMA001 (BC-NKA-20008)

EXPERIMENTAL

ZMA001 is a fully human, monoclonal antibody (IgG1) that inhibits migration of activated monocytes and macrophages and reduces pulmonary vascular remodeling and pulmonary artery pressure in pre-clinical rodent models of pulmonary arterial hypertension (PAH).

Drug: ZMA001 (BC-NKA-20008)
