Novel And Previously Reported Genomic Alterations Identified in Clinical Multiple Myeloma Cases Using FoundationOne™ Heme

Comprehensive Genomic Profiling May Lead To New Therapeutic Options For Patients; Data Presented at American Society of Hematology Annual Meeting

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Foundation Medicine today announced new data from a pilot study demonstrating that its fully informative genomic profile for hematologic malignancies, FoundationOne™ Heme, identified both novel and previously reported clinically actionable1 genomic alterations in multiple myeloma cases. These data were presented in an oral presentation titled Pilot Study To Evaluate The Prevalence Of Actionable Oncogenic Mutations In Patients With Relapsed Refractory Multiple Myeloma (abstract number 755) by Alexander Lesokhin, M.D., medical oncologist, Memorial Sloan-Kettering Cancer Center, at the 55thAmerican Society of Hematology Annual Meeting in New Orleans.

"Multiple myeloma is a treatable, but ultimately incurable, blood cancer that eventually becomes resistant to all currently available therapies," said Dr. Lesokhin. "Advances in clinical next-generation sequencing have made it possible to rapidly identify genomic alterations that may be driving a patient's cancer and could inform treatment options leading to advances in clinical development of new targeted therapies in multiple myeloma patients."

In this study, researchers at Memorial Sloan-Kettering used FoundationOne Heme to analyze whole bone marrow aspirate samples from 28 newly diagnosed and 27 heavily pre-treated multiple myeloma patients. High coverage and high quality sequence data was obtained in 98% (54/55) of cases, and alteration prevalence was examined in 63% of (35/55) samples with sufficient plasma cell content. In the analysis:

  • A high frequency of alterations in the MAPK pathway was observed, including mutually exclusive alterations in NRAS and KRAS in 48% of cases, and BRAF V600E alteration in 3% of cases.
  • Fourteen percent of cases had TET2 frameshift/nonsense alterations or IDH2 alterations, suggesting the DNA hydroxymethylation pathway is targeted by recurrent somatic alterations in multiple myeloma.
  • Alterations in epigenetic modifiers were identified in 41% of cases, including alterations in TET2/IDH, chromatin modifying enzymes/scaffolds (ARID1A, ASXL1) and DNA methyltransferases (DNMT3A).
  • Novel alterations in DNA repair pathways (ATM, FANCA, FANCD2) and in FAT3 were identified, suggesting there are novel disease alleles which require functional investigation for their role in multiple myeloma pathogenesis.

"These data support the clinical utility of FoundationOne Heme and the benefit of our comprehensive genomic profiling approach in identifying oncogenic drivers in multiple myeloma," said Vincent Miller, M.D., chief medical officer, Foundation Medicine. "MEK/RAF inhibition has demonstrated clinical efficacy in a range of cancers and there are emerging data that epigenetic and targeted therapies may provide benefit in patients with TET2/IDH mutations. Therefore, these results demonstrate that FoundationOne Heme can identify clinically actionable alterations that may support the clinical development of new treatment options and advance precision medicine for multiple myeloma patients."

About FoundationOne™ Heme

FoundationOne Heme is a fully informative genomic profile for hematologic cancers (leukemia, lymphoma and myeloma), as well as many sarcomas and pediatric cancers, designed to provide physicians with clinically actionable information to guide treatment options for patients based on the genomic profile of their cancer. It is Foundation Medicine's second commercially available targeted sequencing assay and was developed in collaboration with Memorial Sloan-Kettering Cancer Center. Using next-generation sequencing in routine cancer specimens, FoundationOne Heme interrogates all genes somatically altered in these cancers that are validated targets for therapy or unambiguous drivers of oncogenesis based on current knowledge. The test employs RNA sequencing in addition to DNA sequencing to simultaneously detect all classes of genomic alterations, including base pair substitutions, insertions and deletions, copy number alterations and rearrangements, and gene fusions (a type of alteration that is a common driver of hematologic malignancies. sarcomas and pediatric cancers). FoundationOne Heme fits easily into the clinical workflow of the ordering physician, and test results are provided in an easy-to-interpret report supported by a comprehensive review of published literature. FoundationOne Heme is a laboratory-developed test performed at Foundation Medicine's CLIA-certified lab. Please visit www.FoundationOne.com for more information.
