Summary

Brief summary

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.
