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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 testing a new whole genome sequencing approach called ChromoSeq for patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Researchers want to see if ChromoSeq can find more genetic changes than current standard tests, and if it can be used in real-time clinical care. About 325 adults will participate, and doctors will also be surveyed about how useful the new test is.

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, ChromoSeq could become a more comprehensive and faster genetic test for blood cancers, helping doctors choose better treatments.
What could go wrong
This is an early feasibility study, not a treatment trial. It may show no advantage over current tests, and results may not apply to all patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 325 people

The number the study aims to enrol. It can still change while the study runs.

Started

Sep 2021

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

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

Inclusion Criteria Patient * Patient with a clinical suspicion for a new diagnosis of AML or MDS for whom the diagnostic molecular testing via the hematologic molecular algorithm (HMA) at BJH is requested or planned to be requested. * Adult patients 18 years or older. * Ability to understand and willingness to sign an IRB approved written informed consent document. Inclusion Criteria Physician * Treating physician at Washington University School of Medicine who directs therapy for individuals with hematologic malignancies. * Able and willing to complete standardized questionnaires about usability, and stakeholder perceptions of ChromoSeq during the ChromoSeq implementation process. Exclusion Criteria Patient * Younger than 18 years of age Exclusion Criteria Physician * Does not treat patients at Washington University School of Medicine
