NCT ID NCT07670156

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 Results may not be published yet.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.

Summary

This study tests the drug upadacitinib (Rinvoq) in 30 people with rare genetic disorders that overactivate the JAK-STAT immune pathway. The trial has four phases over 12 months, including an open-label phase to find the best dose and a randomized withdrawal phase to compare the drug against placebo. The goal is to see if the drug is safe and can prevent disease flares.

What this could mean

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

Active substance
Upadacitinib (Rinvoq), a JAK inhibitor taken as a daily tablet
What this could lead to
If successful, this could provide a first approved treatment option for people with rare JAK-STAT disorders, helping control immune symptoms.
What could go wrong
This is an early-phase trial with only 30 participants, so results may not apply broadly. The drug may cause side effects or fail to prevent disease flares.
