Clinical Trial 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. 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. After a screening visit, participants will have 1 inpatient visit and up to 6 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.


Clinical Trial Description

Study Description: 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). The current first-in-human, randomized, double-blind, placebo-controlled, single ascending-dose study will determine the safety, tolerability, and pharmacokinetics of intravenous ZMA001 in healthy subjects. Objectives: Primary Objective: Safety and tolerability of ZMA001 in healthy subjects Secondary Objectives: Determine the pharmacokinetics of ZMA001 in healthy subjects following a single, intravenous dose Endpoints: Primary Endpoint: The number of all-cause, treatment-emergent adverse events, grade 1 and above (following CTCAE v5.0 criteria) through day 113 Secondary Endpoints: For each ZMA001 dose level (1.5, 5, 12 and 20 mg/kg), the following will be determined [Timeframe: Pre-infusion, end of infusion, 2, 4, 8, 12, 24, and 48h; Days 8, 29, 57, 85 and 113]: 1. Time to peak drug concentration (Tmax) 2. Peak drug concentration (Cmax) 3. Area under the drug concentration-time curve (AUC) 4. Elimination half-life ;
