ChromoSeq testing in kids with ALL to help classify at diagnosis
Official title: A Prospective Study of Whole Genome Sequencing (ChromoSeq®) at Diagnosis for Pediatric, Adolescent, and Young Adult Acute Lymphoblastic Leukemia (ALL) Patients
Run by Washington University School of Medicine · NCT07313592 · Data updated 2026-11-12
This study tests how well ChromoSeq® genetic sequencing can classify pediatric and young adult patients with suspected ALL using samples collected at initial workup.

Is this trial a fit for you?
✓Likely a good fit
Children and young adults under 30 with suspected ALL (B-ALL or T-ALL) at St. Louis Children’s Hospital/Washington University.
✕Probably not a fit
Patients whose disease does not yield actionable information from ChromoSeq® or who do not undergo the assay will not receive any study-specific benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study collects bone marrow and/or blood samples from up to 60 children and young adults with suspected ALL to try ChromoSeq® for upfront classification in real time. Patients are followed for clinical outcomes for up to about five and a half years. The protocol does not prescribe treatment choices and allows concurrent participation in other therapeutic trials. The aim is to determine the feasibility of using this sequencing assay as part of standard care to guide initial classification of ALL. Enrollment is at St. Louis Children’s Hospital/Washington University in St. Louis.
Why it matters
Potential benefit: If feasible, ChromoSeq® could provide earlier or more precise upfront classification to inform future treatment decisions for pediatric and young adult ALL patients.
How similar studies have gone: Prior studies in leukemia genomics have shown sequencing-based classification can be informative; this study specifically assesses feasibility in a real-world, upfront setting.

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.
