What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This phase 2 trial is testing whether the experimental drug luvometinib, taken alone or with the chemotherapy drug cytarabine, can control Langerhans cell histiocytosis—a rare disease where immune cells build up and damage tissues. People aged 10 and older who need systemic treatment will receive luvometinib for six cycles. If their disease responds well, they continue on luvometinib alone; if not, they may also get cytarabine. The study aims to see how many participants achieve a significant reduction in disease activity.

What this could mean

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

Active substance
luvometinib, an experimental drug taken orally, sometimes combined with the chemotherapy drug cytarabine
What this could lead to
If successful, this could offer a new targeted treatment option for people with Langerhans cell histiocytosis, potentially reducing the need for more aggressive therapies.
What could go wrong
This is a small, early-phase trial with only 30 participants, so results may not apply broadly. Side effects from luvometinib and cytarabine are possible, and the treatment may not work for everyone.
