CAMBRIDGE, Mass., Nov. 05, 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 third quarter ended September 30, 2024, and provided a corporate update.

"We are focused on the advancement of BDTX-1535 for the treatment of patients with EGFRm NSCLC and look forward to providing clinical updates on our Phase 2 trial for both newly diagnosed patients and patients with relapsed/refractory EGFRm NSCLC in the first quarter of 2025," said Mark Velleca, M.D., Ph.D., Chief Executive Officer of Black Diamond Therapeutics. "We also look forward to sharing feedback on a registrational path in relapsed/refractory EGFRm NSCLC following a meeting planned with the FDA in the first quarter of 2025."

Recent Developments & Upcoming Milestones:

BDTX-1535:

• In September 2024, Black Diamond announced initial Phase 2 data demonstrating encouraging clinical responses and durability of BDTX-1535 in patients with relapsed/refractory epidermal growth factor receptor (EGFR) mutant (EGFRm) non-small cell lung cancer (NSCLC). The 200 mg daily dose of BDTX-1535 was selected for pivotal development, showing robust EGFRm target coverage and a favorable tolerability profile with no new safety signals observed. A preliminary overall response rate (ORR) of 42% was seen in 19 patients with known osimertinib resistance EGFR mutations (either C797S or PACC "P-loop αC-helix compressing" mutations). Encouraging durability was noted with a duration of response (DOR) of approximately eight months or more in the first three patients who achieved a partial response (PR), while 14 of the 19 patients remained on treatment.
• In September 2024, Black Diamond presented a poster analyzing real-world treatment outcomes for newly diagnosed NSCLC patients with non-classical EGFR mutations (NCMs) at the 2024 European Society for Medical Oncology (ESMO) Congress. The analyses revealed the presence of a broad spectrum of NCMs, including PACC mutations, and allowed association with real-world treatment practices and therapeutic outcomes. Findings further demonstrated that current treatment practices for patients with NCMs are heterogenous: 36% of patients received osimertinib or afatinib and 60% of patients received chemotherapy and/or immunotherapy.
• In October 2024, the Ivy Brain Tumor Center, which is sponsoring a "window of opportunity" (also known as Phase 0/1 "Trigger") trial of BDTX-1535 in patients with recurrent high-grade glioma (HGG), presented updated study results demonstrating that BDTX-1535 effectively penetrates rarely accessible regions of glioblastoma and suppresses EGFR signaling in patient tumors at the 19th Meeting of the European Association of Neuro-Oncology. These encouraging data provide rationale for the program's expansion into newly diagnosed glioblastoma patients with EGFR aberrations.
• In the first quarter of 2025, Black Diamond expects to disclose initial Phase 2 data in first-line EGFRm NSCLC patients with non-classical mutations as well as updated Phase 2 results in the recurrent EGFRm NSCLC setting (NCT05256290) together with an update on a potential registrational path for the recurrent setting.

Corporate

• In October 2024, Black Diamond announced a corporate restructuring plan to prioritize its resources on advancing and optimizing development plans for its lead program BDTX-1535, strengthen operational efficiencies and extend the Company's expected cash runway into the second quarter of 2026. As part of the restructuring, Black Diamond also deprioritized its Phase 1 RAS/RAF inhibitor, BDTX-4933, and is actively seeking partnerships for the program.

Financial Highlights

• Cash Position: Black Diamond ended the third quarter of 2024 with approximately $112.7 million in cash, cash equivalents, and investments compared to $131.4 million as of December 31, 2023. Net cash used in operations was $11.3 million for the third quarter of 2024 compared to $18.4 million for the third quarter of 2023.
• Research and Development Expenses: Research and development (R&D) expenses were $12.9 million for the third quarter of 2024, compared to $16.2 million for the same period in 2023. The decrease in R&D expenses was primarily due to workforce efficiencies and reduced spending on early discovery projects.
• General and Administrative Expenses: General and administrative (G&A) expenses were $5.2 million for the third quarter of 2024, compared to $7.9 million for the same period in 2023. The decrease in G&A expenses was primarily due to a decrease in consulting and other professional fees.
• Net Loss: Net loss for the third quarter of 2024 was $15.6 million, as compared to $23.0 million for the same period in 2023.

Financial Guidance

• Black Diamond ended the third quarter of 2024 with approximately $112.7 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 2026.
