What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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 whether nelfinavir, a drug originally used for HIV, can help people with myelofibrosis who have anemia (low red blood cells). The drug aims to restore iron delivery to the bone marrow. Ten adults with myelofibrosis and low hemoglobin will take nelfinavir twice daily to see if their anemia improves and if fibrosis markers decrease.

What this could mean

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

Active substance
Nelfinavir (an HIV drug being repurposed)
What this could lead to
If it works, this could offer a new way to treat anemia in myelofibrosis patients without needing blood transfusions.
What could go wrong
This is a very small early-phase trial with only 10 participants, so results may not apply broadly. The drug may not improve anemia or could cause side effects.
