CAMBRIDGE, Mass., March 12, 2024 (GLOBE NEWSWIRE) -- Black Diamond Therapeutics, Inc. (NASDAQ:BDTX), a clinical-stage oncology company focused on the development of MasterKey therapies to treat patients with genetically defined tumors, today reported financial results for the fourth quarter and full year ended December 31, 2023, and provided a corporate update.

"The year 2023 was exciting, with generation of clinical data that positions BDTX-1535 as a potential first and best in class 4th generation EGFR TKI, and we recently began dosing first-line patients in a Phase 2 trial in NSCLC with non-classical mutations," said Mark Velleca, M.D., Ph.D., President and Chief Executive Officer of Black Diamond Therapeutics. "This year will be data rich across our pipeline, with Phase 2 data for BDTX-1535 in NSCLC, additional GBM results, and initial Phase 1 data for BDTX-4933 in non-G12C KRAS mutated NSCLC."

Recent Developments & Upcoming Milestones:

BDTX-1535:

• In October 2023, Black Diamond presented a poster with updated clinical data at the European Organization for Research and Treatment of Cancer-National Cancer Institute-American Association for Cancer Research (EORTC-NCI-AACR) Symposium on Molecular Targets and Cancer Therapeutics from the dose escalation portion of the Phase 1 clinical trial of BDTX-1535 in patients with non-small cell lung cancer (NSCLC). The presentation included clinical data from 27 patients with advanced/metastatic NSCLC who received once daily doses ranging from 25mg to 400mg. These results demonstrated a favorable tolerability profile and durable responses in patients with NSCLC expressing both acquired resistance C797S and non-classical driver epidermal growth factor receptor (EGFR) mutations.
• 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 a Phase 2 cohort in first-line (1L) patients with non-classical EGFR mutations in early 2024. (NCT05256290)
• Phase 0/1 "window of opportunity" clinical trial of BDTX-1535 began enrollment in October 2023 to evaluate the pharmacokinetic, pharmacodynamic, and clinical response in patients with recurrent high-grade glioma (HGG) with EGFR alterations and/or fusions who are undergoing a planned surgical resection. The trial is sponsored by the Ivy Brain Tumor Center in Phoenix, Arizona. (NCT06072586)
• Top-line results disclosed in December 2023 from the Phase 1 dose escalation trial of BDTX-1535 in patients with relapsed/recurrent glioblastoma (GBM) showed clinical activity in heavily pretreated patients. BDTX-1535 was shown to be generally well tolerated, with no new safety signals observed.
• Black Diamond anticipates the following upcoming key milestones for BDTX-1535:
  • Oral presentation describing real world data of the evolving EGFR mutation landscape in patients with NSCLC, and the MasterKey profile of BDTX-1535 addressing a broad spectrum of mutations at the American Association for Cancer Research (AACR) annual meeting on April 7, 2024.
  • Phase 2 clinical data in patients with NSCLC and non-classical driver or acquired resistance EGFR mutations in the third quarter of 2024.
  • Phase 1 dose escalation data in patients with relapsed/recurrent GBM, and initial results from the investigator sponsored "window of opportunity" trial in patients with recurrent HGG are expected to be presented at a medical meeting in the second quarter of 2024.

BDTX-4933:

• In October 2023, Black Diamond presented a poster at the EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics detailing preclinical data for the clinical-stage MasterKey RAF inhibitor BDTX-4933, a brain-penetrant oral inhibitor of oncogenic alterations in KRAS, NRAS and BRAF. Preclinical results showed that BDTX-4933 potently and selectively inhibited the proliferation of tumor cells expressing a range of KRAS, NRAS and BRAF mutations, suggesting clear differentiation compared to other RAF inhibitors.
• A Phase 1 clinical trial for BDTX-4933 was initiated in the second quarter of 2023 in patients with BRAF and select RAS/MAPK mutation-positive cancers, with an emphasis on patients with KRAS mutant NSCLC. The trial is currently in dose escalation with an update anticipated in the fourth quarter of 2024. (NCT05786924)

Financial Highlights

• Cash Position: Black Diamond ended 2023 with approximately $131.4 million in cash, cash equivalents, and investments compared to $122.8 million as of December 31, 2022. Net cash used in operations was $66.7 million for the year ended December 31, 2023 compared to $85.1 million for the year ended December 31, 2022.
• Research and Development Expenses: Research and development (R&D) expenses were $15.3 million for the fourth quarter of 2023, compared to $14.6 million for the same period in 2022. Research and development expenses were $59.4 million for the year ended December 31, 2023, compared to $64.4 million for the year ended December 31, 2022. The decrease in R&D expenses was primarily due to reduced spending on early discovery projects as we deepen our focus on our clinical-stage assets.
• General and Administrative Expenses: General and administrative (G&A) expenses were $5.6 million for the fourth quarter of 2023, compared to $7.2 million for the same period in 2022, and $27.1 million for the year ended December 31, 2023, compared to $28.4 million for the year ended December 31, 2022. The decrease in G&A expenses was primarily due to a decrease in legal and other professional fees.
• Net Loss: Net loss for the fourth quarter of 2023 was $19.4 million, as compared to $21.1 million for the same period in 2022. Net loss for the year ended December 31, 2023 was $82.4 million compared to $91.2 million for the year ended December 31, 2022.

Financial Guidance

• Black Diamond ended 2023 with approximately $131.4 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 second quarter of 2025.
