Brief summary
This research study is seeking to gain new knowledge about Recurrent, Refractory, or High Risk Leukemias in children and young adults. This study is evaluating the use of specialized testing called leukemia profiling. Once the profiling is performed, the results are evaluated by an expert panel of physicians, scientists and pharmacists. This may result in a recommendation for a specific cancer therapy or a clinical trial called matched targeted therapy (MTT). The results of the leukemia profiling and, if applicable, the MTT recommendation will be communicated to the participant's primary oncologist.
Detailed description
Our tissues and organs are made up of cells. Cancer occurs when the molecules that normally control cell growth are damaged. The damage results in unchecked cell growth which causes a tumor, a collection of cancer cells. The damage is referred to as an alteration. There are different types of cancer-causing alterations. Genes are the part of cells that contain the instructions which tell our cells how to make the right proteins to grow and work. Genes are composed of Deoxyribonucleic Acid (DNA) letters that spell out these instructions. By participating in this study, the participant's leukemia cells will be tested for cancer causing alterations. This testing is called leukemia profiling. The leukemia profiling will be performed using bone marrow or blood that has already been obtained during a clinical test. Alternately, the profiling may be done on leukemia cells that are planned to be obtained as part of routine clinical care. This study will determine whether it is possible to use profiling results to determine a matched targeted therapy for patients with leukemia. It will describe the range of mutations found in patients with leukemia with this type of profiling, and describe the clinical outcomes of patients who receive a matched targeted therapy.
Interventions
Genetic profiling of leukemia cells will be performed and analyzed by an expert panel. Matched targeted therapy recommendation based on profiling results will be made if available. The recommendation, if available, will be communicated to the primary oncologist.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate of Patients With Actionable Alterations | Actionable alteration was identified based on a combination of fluorescence in situ hybridization (FISH)/cytogenetics and sequencing. Average time to full results was 2 weeks. | An actionable alteration was defined as a cancer-associated genomic event for which there was a targeted drug available. Actionable genetic alterations were identified by a combination of standard-of-care cytogenetics/fluorescence in situ hybridization (FISH) and sequencing performed as part of the study. This study is considered feasible if at least 13% of participants analyzed have profile data and identifiable actionable alterations. A 90% exact binomial confidence interval is presented for the rate of patients with actionable alterations to compare the observed rate against 13%. |

Outcome results
Rate of Patients With Actionable Alterations
An actionable alteration was defined as a cancer-associated genomic event for which there was a targeted drug available. Actionable genetic alterations were identified by a combination of standard-of-care cytogenetics/fluorescence in situ hybridization (FISH) and sequencing performed as part of the study. This study is considered feasible if at least 13% of participants analyzed have profile data and identifiable actionable alterations. A 90% exact binomial confidence interval is presented for the rate of patients with actionable alterations to compare the observed rate against 13%.
Time frame: Actionable alteration was identified based on a combination of fluorescence in situ hybridization (FISH)/cytogenetics and sequencing. Average time to full results was 2 weeks.
Population: The analysis dataset is comprised of the first 100 patients in Cohort 1, as defined per protocol. One patient in Cohort 2 was later identified to have relapsed/refractory disease, so therefore the analysis population contains 101 patients. The remainder of Cohort 1 patients and the entirety of Cohort 2 patients are represented in the analysis of secondary outcomes.
