A Study to Evaluate Safety and Pharmacokinetics of ZB002 in Healthy Participants and Participants With Rheumatoid Arthritis

Официальное название

A Phase 1, 2-Part, Single Ascending Dose (SAD) Study to Evaluate the Safety and Pharmacokinetics (PK) of ZB002 in Healthy Volunteers (HVs) and Multiple Ascending Dose (MAD) Study to Evaluate the Safety and PK of ZB002 in Participants With Rheumatoid Arthritis (RA)

Обзор

This double-blind, randomized, placebo-controlled study will assess the safety and pharmacokinetics of ZB002 in healthy participants and in participants with rheumatoid arthritis (RA). The study consists of 2 parts. Part A: Single Ascending Dose (SAD), which will include only healthy volunteers. Part B: Multiple Ascending Dose (MAD), will commence after completion of the SAD study and will include RA participants.

Подробное описание

Part A (SAD): Up to approximately 48 healthy volunteers across 6 cohorts randomized to receive ZB002 or placebo as a single dose.

Part B (MAD): Up to approximately 24 participants with RA across 3 cohorts randomized to receive ZB002 or placebo as multiple doses.

Main Exclusion Criteria

Part A SAD (HV):

• Surgery within 4 weeks before Screening or planned surgery during the clinical study.
• Use of prescription medications, biological products, or other medicines within 2 weeks before Study Day 1 or 5 half-lives of the product, whichever is greater. Use of over-the-counter medications or vitamins/dietary supplements within 7 days of dosing unless considered by the Investigator to not pose a risk or impact the study results.
• Treatment with any investigational drug within 30 days or 5 half-lives, whichever is greater, before the first dose of the study drug, or currently enrolled in another clinical study.
• Clinically significant ECG abnormality.
• Positive for HIV infection, active hepatitis C, or hepatitis B.
• Positive for COVID-19 virus.
• Positive QuantiFERON®-TB Gold or T-SPOT® test for Mycobacterium tuberculosis.
