CAMBRIDGE, MA, May 09, 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, today reported financial results for the first quarter ended March 31, 2024, and provided a corporate update.

“We reached an important inflection in BDTX-1535 development this past quarter, as we initiated dosing of patients with non-classical EGFR mutant NSCLC in the first-line setting, and are on track to release initial results from the ongoing Phase 2 second/third-line cohorts in the third quarter of this year ”, said Mark Velleca, M.D., Ph.D., Chief Executive Officer of Black Diamond Therapeutics. “Our recent AACR presentation on the evolving EGFR mutation landscape highlights the major unmet need in EGFR mutant NSCLC, and the differentiated BDTX-1535 profile as the potential first- and best-in-class fourth-generation oral TKI in clinical development addressing the full spectrum of classical, non-classical, and C797S resistance mutations in NSCLC.”

Recent Developments & Upcoming Milestones

BDTX-1535

• Following receipt of End of Phase 1 feedback from the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2023, Black Diamond initiated dosing of a Phase 2 first-line cohort in patients with non-classical epidermal growth factor receptor mutation positive (EGFRm) non-small cell lung cancer (NSCLC) during the first quarter of 2024. (NCT05256290)
• In April 2024, Black Diamond described real world evidence of the evolving EGFR mutation landscape in patients with NSCLC and the potential of BDTX-1535 to address a broader range of mutations compared to existing therapies at the 2024 American Association for Cancer Research (AACR) annual meeting. The oral presentation titled “BDTX-1535 – A MasterKey EGFR Inhibitor Targeting Classical, Non-Classical and the C797S Resistance Mutation to Address the Evolved Landscape of EGFR Mutant NSCLC,” evaluated more than 235,000 sequenced cases of NSCLC sourced from Guardant Health (GuardantINFORM™) and Foundation Medicine (FoundationInsights™). The analyses revealed a broad spectrum of non-classical mutations, as well as an increased prevalence of the acquired resistance mutation, C797S. These non-classical EGFR mutations were present in 20-30% of newly diagnosed EGFRm NSCLC patients.
• Black Diamond anticipates the following upcoming key milestones for BDTX-1535:
  • Poster presentations at the American Society of Clinical Oncology (ASCO) Annual Meeting on June 1, 2024, of Phase 1 dose escalation data in patients with relapsed/recurrent GBM, and initial intratumoral pharmacokinetic results from a “window of opportunity” (also known as a Phase 0/1 “Trigger”) trial sponsored by the Ivy Brain Tumor Center, in patients with recurrent high-grade glioma (HGG).
  • Disclosure of initial Phase 2 data in 2L/3L EGFRm NSCLC patients with non-classical mutations or the acquired resistance C797S mutation remains on track for Q3 2024.

BDTX-4933

• Enrollment of patients with BRAF and select RAS/MAPK mutation-positive cancers, with an emphasis on patients with KRAS mutant NSCLC is ongoing in a Phase 1 dose escalation trial of BDTX-4933, a brain-penetrant oral inhibitor of oncogenic alterations in KRAS, NRAS and BRAF (NCT05786924). An update from this trial is anticipated in Q4 2024.

Corporate

• In April 2024, the Company announced changes to its Board of Directors. Industry veterans Shannon Campbell and Prakash Raman, Ph.D., have been appointed to the Company’s Board of Directors. In addition, Wendy Dixon, Ph.D., and Alex Mayweg, Ph.D., have stepped down as members of the Board of Directors.

Financial Highlights

• Cash Position: Black Diamond ended the first quarter of 2024 with approximately $115.2 million in cash, cash equivalents, and investments compared to $131.4 million as of December 31, 2023. Net cash used in operations was $21.2 million for the first quarter of 2024 compared to $20.0 million for the first quarter of 2023.
• Research and Development Expenses: Research and development (R&D) expenses were $13.5 million for the first quarter of 2024, compared to $14.8 million for the same period in 2023. The decrease in R&D expenses was primarily due to reduced spending on early discovery projects.
• General and Administrative Expenses: General and administrative (G&A) expenses were $6.7 million for the first quarter of 2024, compared to $6.8 million for the same period in 2023. The decrease in G&A expenses was primarily due to a decrease in personnel related costs and legal and other professional fees.
• Net Loss: Net loss for the first quarter of 2024 was $18.2 million, as compared to $20.9 million for the same period in 2023.

Financial Guidance

• Black Diamond ended the first quarter of 2024 with approximately $115.2 million in cash, cash equivalents and investments which the Company believes is sufficient to fund its anticipated operating expenses and capital expenditure requirements into the third quarter of 2025.
