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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is looking for the genetic mutation that causes polycythemia (too many red blood cells) and thrombocytosis (too many platelets). Researchers will analyze blood samples from 200 participants to identify the faulty gene. Finding this gene could help design new treatments to control or even cure these conditions in the future.

What this could mean

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

What this could lead to
If successful, this research could identify the genetic mutation causing these blood disorders, paving the way for future targeted therapies.
What could go wrong
This is an observational study, not a treatment trial. Finding the genetic cause does not guarantee that effective treatments will be developed.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Subjects with an elevated hemoglobin concentration (\>18 in males and \>16 in females) 2. Subjects with an elevated platelet count (\>450,000) Exclusion Criteria: 1.
