CAMBRIDGE, Mass. and NEW YORK, April 10, 2021 (GLOBE NEWSWIRE) — Black Diamond Therapeutics, Inc. (Nasdaq: BDTX), a precision oncology medicine company pioneering the discovery and development of small molecule, MasterKey therapies, today announced the presentation of preclinical data on BDTX-189 and BDTX-1535 at the American Association for Cancer Research Annual Meeting (AACR), taking place April 9-14, 2021.
“These preclinical data demonstrate achievement of a key goal of our pharmacokinetic (PK)/pharmacodynamic (PD) strategy for BDTX-189 with a preclinical PK/PD profile designed for rapid and sustained target inhibition with rapid clearance,” said Elizabeth Buck, Ph.D., Executive Vice President, Discovery and Translational Sciences at Black Diamond Therapeutics. “We look forward to presenting preliminary clinical data, including detailed PK data, from the Phase 1 dose-escalation portion of the MasterKey-01 study in the first half of this year.”
Dr. Buck continued: “Additionally, these data illustrate the MasterKey profile of BDTX-1535 as a brain-penetrant, epidermal growth factor receptor (EGFR) mutant selective inhibitor. BDTX-1535 has been shown to potently and selectively inhibit the family of EGFR variants implicated in glioblastoma multiforme (GBM), as well as Exon 18 mutations and the C797S mutations evident in non-small cell lung cancer (NSCLC). This breadth of coverage, coupled with a brain-penetrant PK profile, supports the potential to develop a novel and differentiated candidate for GBM and solid tumors expressing un-drugged EGFR mutations, including NSCLC.”
The presentations describe the following data:
Preclinical PK BDTX-189 Data:
Preclinical BDTX-1535 Data:
“Collectively, these data support the differentiated profiles of both BDTX-189 and BDTX-1535, the foundation of our ErbB franchise, and our ability to develop novel therapies for patients with genetically defined cancers,” said David M. Epstein, Ph.D., President and Chief Executive Officer of Black Diamond Therapeutics.
The presentations from the AACR meeting are available on the “Scientific Presentations and Publications” section of the Black Diamond Therapeutics website.
About BDTX-189
BDTX-189 is an orally available, irreversible small molecule inhibitor that is designed to block the function of family of oncogenic proteins defined by driver mutations across a range of tumor types, and which affect both of the epidermal growth factor receptor (EGFR) and the tyrosine-protein kinase, ErbB-2, or human epidermal growth factor receptor 2 (HER2). BDTX-189 is designed as a MasterKey inhibitor targeting a family of previously undrugged and functionally similar mutations in a tumor-agnostic manner. These mutations include extracellular domain allosteric mutations of HER2, as well as EGFR and HER2 kinase domain Exon 20 insertions, and additional activating oncogenic drivers of ErbB. The ErbB receptors are a group of receptor tyrosine kinases involved in key cellular functions, including cell growth and survival. BDTX-189 is also designed to spare normal, or wild-type, EGFR, which we believe has the potential to improve upon the toxicity profiles of current ErbB kinase inhibitors. Currently, there are no medicines approved by the U.S. Food and Drug Administration (FDA) to target all of these oncogenic mutations with a single therapy.
BDTX-189 is currently being evaluated in a Phase 1/2 clinical trial (MasterKey-01) in adult patients with advanced solid tumors with at least one MasterKey mutation who have no standard therapy available or for whom standard therapy is considered unsuitable or intolerable. In July 2020, the FDA granted Fast Track designation to BDTX-189 for the treatment of adult patients with solid tumors harboring an allosteric HER2 mutation or an EGFR or HER2 Exon 20 insertion mutation who have progressed following prior treatment and who have no satisfactory treatment options.
About Black Diamond Therapeutics
Black Diamond Therapeutics is a precision oncology medicine company pioneering the discovery of small molecule, MasterKey therapies. Black Diamond targets undrugged mutations in patients with genetically defined cancers. Black Diamond is built upon a deep understanding of cancer genetics, protein structure and function, and medicinal chemistry. The Company’s proprietary technology platform and drug discovery engine, Mutation-Allostery-Pharmacology, or MAP, platform, is designed to allow Black Diamond to analyze population-level genetic sequencing data to identify oncogenic mutations that promote cancer across tumor types, group these mutations into families, and develop a single small molecule therapy in a tumor-agnostic manner that targets a specific family of mutations, termed a MasterKey therapy. Black Diamond was founded by David M. Epstein, Ph.D., and Elizabeth Buck, Ph.D. For more information, please visit www.blackdiamondtherapeutics.com.
