Whole Genome Sequencing (ChromoSeq®) for Acute Lymphoblastic Leukemia (ALL) Patients

United States60 participantsStarted 2026-06-03

Plain-language summary

This is a prospective specimen collection study evaluating the feasibility of using the ChromoSeq® assay for upfront classification in a real-time clinical setting of pediatric and young adult acute lymphoid leukemia (ALL) patients. Sixty patients will undergo collections of bone marrow and/or peripheral blood for the ChromoSeq® assay at time of initial workup, and the patients will then be followed for clinical outcomes for up to 65 months.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Eligibility Criteria * Children and young adult patients (\< 30 years of age at time of study enrollment) treated at St. Louis Children's Hospital/Washington University School of Medicine. * Suspected diagnosis or suspected relapse of acute lymphoblastic leukemia (ALL), B- or T-cell. * Concurrent enrollment on a prospective therapeutic trial is allowed as this protocol makes no recommendations regarding treatment approach. * Ability to understand and willingness to sign an IRB approved written informed consent document. All patients and/or their parents or legal guardians must sign an IRB approved written informed consent document.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
