NCT ID NCT07286058

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

Summary

This study tests the long-term safety and effectiveness of an oral drug called zasocitinib (TAK-279) in adults with active psoriatic arthritis, a condition causing joint pain and skin patches. About 1,182 participants who completed a one-year parent study will take either a lower or higher dose daily for up to two more years. Researchers will monitor side effects and measure how well the drug controls symptoms over time.

What this could mean

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

Active substance

Zasocitinib (also called TAK-279 or NDI-034858), an oral tablet

What this could lead to

If successful, this could confirm zasocitinib as a safe, long-term daily treatment option to control psoriatic arthritis symptoms and joint damage.

What could go wrong

This is an extension study, so participants already tolerated the drug for a year. However, long-term safety data is still being collected, and rare side effects may emerge over the additional two years.
