Official title
A Phase 1b, Open-label, Dose-Escalation Trial to Evaluate Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Plamotamab in Participants With Rheumatoid Arthritis
Overview
The purpose of this study is to determine the safety and tolerability of plamotamab in patients with rheumatoid arthritis. Participants will be given XmAb13676 subcutaneously (SC) by injection under the skin.
Detailed description
This is a Phase 1b study to determine the safety, tolerability, pharmacokinetic (PK), and pharmacodynamics (PD), and immunogenicity of plamotamab in adult participants with moderately to severely active RA. This is an open label dose optimization trial with approximately 68 participants assigned to different dose escalation cohorts.
