Summary

This completed study looked at how well cladribine tablets work in everyday practice for people with relapsing multiple sclerosis (MS) who had a poor response to other oral or infusion treatments. Researchers tracked 291 participants over 24 months, measuring relapse rates and patient satisfaction. The goal was to see if switching to cladribine improves outcomes in a real-world setting.

What this could mean

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

Active substance: cladribine tablets
What this could lead to: If successful, this could confirm that cladribine tablets are a good option for people with MS who haven't done well on other medications.
What could go wrong: This is an observational study, not a controlled trial, so results may be less reliable. It also only included people who already switched to cladribine, so findings may not apply to everyone.
