Beat AML trial delivers genomic results in 7 days



– Investigators demonstrated the feasibility of delivering genomic results in 7 days in a population of older, newly diagnosed patients with acute myeloid leukemia (AML).

The Beat AML Master Trial is an ongoing umbrella study that harnesses cytogenetic information and next generation sequencing to match patients with targeted therapies across a number of substudies or outside of the trial’s multicenter network.

The researchers chose AML for this precision-medicine study because of its rapid onset and lethal nature, its heterogeneity, and the availability of more-targeted therapies, said Amy Burd, PhD, of the Leukemia & Lymphoma Society, which is sponsoring the study.

Initial data from the trial showed that more than 95% of patients were assigned to treatment in 7 days or less, based on their personalized genomic information.

Overall, 285 patients had usable genomic screening data and were assigned to treatment. Of those patients, 273 were assigned to a treatment within 7 days, Dr. Burd reported at the annual meeting of the American Society of Hematology.

The speed of delivering these results is critical, said Joseph Mikhael, MD, chief medical officer for the International Myeloma Foundation in Phoenix, who moderated a media briefing on personalized medicine.

“One of the greatest challenges we faced in the concept of personalized medicine is by the time you’ve determined what is best for that patient ... the horse is already out of the barn,” Dr. Mikhael said. “You have to have started the patient on treatment already or else their disease could have progressed quite rapidly.”

In the past, genomic results might come back a month after the patient started therapy. “It was really almost academic,” he said.

In the Beat AML study, more than half (146 patients) were treated based on their AML subtype. The remaining patients (139) were not treated: 2.5% of patients died within 7 days, 7% of patients chose an alternative treatment prior to assignment, 20% chose standard of care, 9.1% chose an alternative trial after assignment, 8.1% chose palliative care, and the remainder had a reason that was not specified.

“The treatment decisions are made for what’s best for the patient even if that means a study outside of Beat AML,” Dr. Burd said.

Currently, there are 11 substudies offering treatment to trial participants across 13 clinical sites. There has been promising efficacy in many of the treatment arms, Dr. Burd said.

In the future, the researchers are looking to expand the substudies to look into novel drug combinations for certain AML subtypes, specifically isocitrate dehydrogenase 2–mutated groups.
