Company advancing BDTX-1535 in EGFRm NSCLC towards key inflection points in Q1 2025

Will deprioritize BDTX-4933 and seek potential partners

Anticipated cost savings expected to extend cash runway into Q2 2026

CAMBRIDGE, Mass., Oct. 07, 2024 (GLOBE NEWSWIRE) -- Black Diamond Therapeutics, Inc. (Nasdaq: BDTX), a clinical-stage oncology company developing MasterKey therapies that target families of oncogenic mutations in patients with cancer, announced today a corporate restructuring to focus resources on advancing lead program BDTX-1535 into pivotal development, and to extend the Company’s expected cash runway into Q2 2026. BDTX-1535 has demonstrated robust Phase 2 clinical activity across a broad spectrum of epidermal growth factor receptor mutations (EGFRm) in patients with recurrent non-small cell lung cancer (NSCLC).

In Q1 2025, Black Diamond anticipates sharing initial Phase 2 data for BDTX-1535 in the frontline setting for patients with EGFRm NSCLC. Also in Q1 2025, the Company plans to present updated Phase 2 results for BDTX-1535 in patients with recurrent EGFRm NSCLC and a potential registration path in the recurrent setting based on feedback from the FDA.

Black Diamond is actively seeking partnerships as it deprioritizes its BDTX-4933 program in RAF/RAS-mutant solid tumors. To enable focused investment in BDTX-1535, Black Diamond has also taken steps to optimize operations, including a reduction in force, while retaining core drug development and management expertise. As part of the restructuring, Chief Business Officer and Chief Financial Officer Fang Ni and Chief People Officer Elizabeth Montgomery are departing the Company. Erika Jones, Senior Vice President of Finance and Principal Accounting Officer, has been appointed Principal Financial Officer of the Company. Cost savings from the restructuring and other actions described above are expected to be sufficient to fund operations into Q2 2026.

“BDTX-1535 is a well-tolerated oral TKI with the potential to benefit patients with EGFRm NSCLC across multiple lines of therapy,” said Mark Velleca, M.D., Ph.D., Chief Executive Officer of Black Diamond Therapeutics. “We remain focused on advancing BDTX-1535 and presenting additional Phase 2 data in Q1 2025. I am deeply grateful to each member of the Black Diamond team, whose hard work and valuable contributions have brought us to the threshold of pivotal development for our lead program.”

About BDTX-1535

BDTX-1535 is an oral, brain-penetrant MasterKey inhibitor of oncogenic EGFR mutations in NSCLC, including classical mutations, non-classical mutations, and the C797S resistance mutation. BDTX-1535 is a fourth-generation tyrosine kinase inhibitor (TKI) that potently inhibits, based on preclinical data, more than 50 EGFR mutations expressed across a diverse group of patients with NSCLC in multiple lines of therapy. Based on preclinical data, BDTX-1535 also inhibits EGFR extracellular domain mutations and alterations commonly expressed in glioblastoma (GBM) and avoids paradoxical activation observed with earlier generation reversible TKIs. A “window of opportunity” trial of BDTX-1535 in patients with GBM is ongoing (NCT06072586) and a Phase 2 trial is ongoing in patients with NSCLC (NCT05256290).
