CAMBRIDGE, Mass., March 29, 2019 /PRNewswire/ -- Black Diamond Therapeutics, Inc., a biotechnology company developing next-generationprecision medicines for cancer, today announced that data from its first-in-class program targeting a group of epidermal growth factor receptor (EGFR) allosteric mutants that drive glioblastoma multiforme (GBM) will be presented at the American Association
"Through our MAP platform, we have defined the molecular mechanism by which oncogene activation of a family of extracellular EGFR mutations identified in glioblastoma patients – termed locked-dimer (LoDi)-EGFR oncogenes – renders early generation EGFR inhibitors ineffective," said David Epstein, Ph.D., President and CEO of Black Diamond. "Glioblastoma multiforme is a highly malignant and aggressive cancer for which there exists limited treatment options and these findings set guidelines for the discovery of selective and potent LoDi-EGFR inhibitors."
Elizabeth Buck, Ph.D., co-Founder and Executive Vice President of Discovery and Translational Sciences at Black Diamond, added, "These data describe our fundamental observation that LoDi-EGFR mutants – the first subset of allosteric oncogenic mutations in the ErbB family to be described by Black Diamond Therapeutics – are not only robust oncogenes, but due to their unique mode of homodimerization exhibit new and distinct pharmacology. Taken together, these results highlight the need for critically understanding the functional consequences of all allosteric mutations in the druggable oncogene landscape to help inform the discovery of therapies that have the greatest chances for treatment success."

Black Diamond's MAP: a unique platformBlack Diamond's industry-leading mutation, allostery, and pharmacology (MAP) computational and discovery platform identifies and drugs allosteric mutant disease targets. Oncogenes are activated by kinase domain mutations or by allosteric mutations. While kinase domain mutations have been successfully drugged with selective inhibitors and are standard of care in many malignancies, allosteric mutations represent an undrugged and unexplored space.
As genomic profiling and sequencing of cancer patients is becoming standard clinical practice, Black Diamond's MAP platform pinpoints new druggable families of mutations from the thousands of lesions identified across individual oncogenes derived from cancer patients, thus leading to the creation of high-impact precision medicines. The prevalence of the allosteric mutations in ErbB ranges from two to 15 percent of patients diagnosed with a given tumor type.
Black Diamond's MAP platform has generated a pipeline of five programs, including three that have progressed compounds through lead optimization or into IND-enabling studies. The fourth and fifth programs are in lead identification. Black Diamond's first three disclosed programs are targeting groups of EGFR and HER2 allosteric mutants.
About Black DiamondBlack Diamond Therapeutics is a next-wave cancer precision medicine company. Black Diamond pioneered the development of selective medicines for patients with genetically defined cancers driven by oncogenes activated by allosteric mutations. Using its mutation, allostery, and pharmacology (MAP) computational and discovery platform, Black Diamond is uncovering new ways to functionally assess the mutational landscape of individual oncogenes – to discover and validate new targets and develop novel approaches to creating highly selective therapeutics. Black Diamond was founded by David M. Epstein, Ph.D., Elizabeth Buck, Ph.D., and Versant Ventures, and is the first new company to emerge from Versant's Ridgeline Discovery Engine in Basel, Switzerland.
