Precision Medicine Initiative Aims to Improve Leukemia Treatment
An aggressive cancer in which the bone marrow starts producing large numbers of abnormal blood cells, acute myeloid leukemia is the most common type of acute leukemia in adults. Unfortunately, the overall five-year survival rate for the disease is 30%.
MyeloMATCH is looking to change that. A precision-medicine initiative sponsored by the National Cancer Institute, myeloMATCH (Myeloid Malignancies Molecular Analysis for Therapy Choice) is an “umbrella trial,” a group of clinical substudies for people with acute myeloid leukemia or myelodysplastic syndrome. Myelodysplastic syndrome is another blood cancer that sometimes progresses to acute myeloid leukemia.
A National Priority
The University of Kansas Cancer Center was the first to enroll a participant among over 100 sites. The initiative includes trials developed by the Alliance for Clinical Trials in Oncology, Canadian Cancer Trials Group, ECOG-ACRIN Cancer Research Group and SWOG Cancer Research Network. It is the largest coordinated effort in the US to address myeloid cancers.
“It took a long time to get here, and it’s really exciting to see that this is a national priority for the US leukemia community,” says Tara Lin, MD, director of the adult leukemia program and the site principal investigator for myeloMATCH at the cancer center.
The long-term, big picture goal would be that every person with a new diagnosis could enroll, get rapid diagnostic screening and get assigned to a treatment, and that the myeloMATCH platform could carry them through their whole treatment trajectory. Tara Lin, MD
How It Works
Starting last summer at The University of Kansas Cancer Center and Masonic Cancer Alliance member institutions, myeloMATCH is open to people ages 18 or over who are believed to have acute myeloid leukemia or myelodysplastic syndrome. Participants are screened at diagnosis for specific biomarkers in their blood and bone marrow – e.g., particular gene mutations or certain proteins – and based on those results, are assigned to a myeloMATCH substudy that targets these genetic or molecular characteristics.
Diagnostic testing offered by myeloMATCH takes just 72 hours, instead of weeks. “This access to rapid diagnostic information, you really can't get through any other mechanism,” she says.
If no suitable substudy is available, that participant receives standard-of-care treatment from their physician and may be eligible for a trial at a later treatment stage for their disease.
Breaking New Ground
Dr. Lin is the national co-leader, along with a researcher at the University of Utah, of one of the substudies currently offered under myeloMATCH. The substudy is for acute myeloid leukemia patients under age 60 with high-risk disease that is more difficult to treat and has a higher rate of recurrence. This trial will test newer experimental treatment regimens with additional drugs against the current standard-of-care and compare the results. The goal is to help more people achieve minimal residual disease (MDR) negativity, which means they have even fewer cancer cells left than the proportion indicating that a patient has gone into remission.
“We know that MRD status really predicts someone's long-term survival,” says Dr. Lin.
Another substudy is looking at adding a new drug to the treatment of patients over age 60 who have the most common gene mutation in acute myeloid leukemia, a mutation in the FLT3 gene.
“This is the first time that we have made an effort like this (for this group of cancers) in the United States, to get together and do a trial at the same time with many institutions involved,” says Jesus Gonzalez Lugo, MD, assistant professor of Hematologic Malignancies and Cellular Therapeutics at the University of Kansas Medical Center and the principal investigator for the FLT3 trial at The University of Kansas Cancer Center.
The number of substudies offered under the myeloMATCH umbrella will grow over time.
“The purpose of myeloMATCH is to become an entire pipeline of trials,” says Dr. Lin. “The long-term, big picture goal would be that every person with a new diagnosis could enroll, get rapid diagnostic screening and get assigned to a treatment, and that the myeloMATCH platform could carry them through their whole treatment trajectory.”
