  • Announced encouraging initial Phase 2 data of BDTX-1535 in patients with recurrent EGFRm NSCLC with a broad spectrum of classical, non-classical, and C797S resistance mutations in September 2024

  • Presented real-world treatment practices and patient outcomes in newly diagnosed NSCLC patients with non-classical EGFR mutations at the 2024 ESMO Congress

  • Clinical updates of BDTX-1535 in EGFRm NSCLC and regulatory feedback expected in Q1 2025

  • Cash, cash equivalents, and investments of $112.7 million as of September 30, 2024; expected to be sufficient to fund operations into Q2 of 2026

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.
