New injection aims to tame rheumatoid arthritis

NCT ID NCT07230353

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-stage trial is testing a new biologic drug called plamotamab in 68 adults with moderate to severe rheumatoid arthritis (RA) who haven't gotten enough relief from other treatments. The drug is given as a shot under the skin, and the main goal is to see if it's safe and tolerable. Researchers will also measure how the drug moves through the body.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

plamotamab (a biologic drug given as an injection under the skin)

What this could lead to

If it works, this could point toward a new treatment option for people with rheumatoid arthritis who haven't responded well to other therapies.

What could go wrong

This is a very early Phase 1 trial with only 68 participants, so it's primarily checking safety, not effectiveness. The drug may cause side effects or not work as hoped.
