Study of Intravenous ZMA001 in Healthy Subjects

Study Overview
=================
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. 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.

Detailed 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]: Time to peak drug concentration (Tmax) Peak drug concentration (Cmax) Area under the drug concentration-time curve (AUC) Elimination half-life

Common non-prescription medications such as (but not limited to) acetaminophen, ibuprofen, or anti-histamines are allowed up to 24 hours prior to dosing. Body mass index less than 17 or greater than 32 kg/m^2 Clinically significant abnormal results on clinical blood testing completed at the Screening Visit Electrocardiographic evidence of clinically relevant heart disease Use of vitamins, herbal supplements, or similar products within the past 2 weeks Blood donation equal to or above 500 mL within 2 months prior to dosing.
