CAMBRIDGE, Mass. and NEW YORK, March 09, 2023 (GLOBE NEWSWIRE) -- Black Diamond Therapeutics, Inc. (Nasdaq: BDTX), a clinical-stage precision oncology medicine company developing MasterKey therapies designed to overcome limitations of existing therapies by targeting families of oncogenic driver mutations in patients with genetically defined cancers, today reported financial results for the fourth quarter and full year ended December 31, 2022, and provided a corporate update.

“We expect 2023 to be a catalyst rich year for Black Diamond following tremendous progress for our two novel MasterKey inhibitors, with BDTX-1535 continuing to advance through our Phase 1 clinical trial and BDTX-4933 meeting critical milestones to further progress toward the clinic. The clearance of the Investigational New Drug (IND) application for BDTX-4933 by the U.S. Food and Drug Administration (FDA) earlier this year marks our third IND allowance in three years and demonstrates the strength of our MAP drug discovery engine along with the expertise of our research and clinical teams. We are driven by the clear unmet need for next-generation precision medicines to treat cancers by overcoming resistance, minimizing on-target and wild-type mediated toxicities, and addressing brain disease. We’ve designed a robust pipeline of products with brain penetration properties to address these key challenges,” said David Epstein, Ph.D., President and Chief Executive Officer of Black Diamond. “We anticipate a clinical update for BDTX-1535 in the second half of 2023. We also expect to initiate the Phase 1 clinical trial of BDTX-4933 in the first half of this year and to progress our FGFR program and another undisclosed program toward development candidate nominations in 2023. As we continue to mature our pipeline, we are acutely focused on delivering meaningful benefit to patients and we believe that our approach has the potential to strengthen the treatment landscape for genetically defined cancers.”

Recent Developments & Upcoming Milestones:

BDTX-1535:

• BDTX-1535, an epidermal growth factor receptor (EGFR) MasterKey inhibitor, is being developed to treat genetically defined cancer in patients whose tumors are positive for EGFR MasterKey mutations in glioblastoma multiforme (GBM), as well as in non-small cell lung cancer (NSCLC). BDTX-1535 is fourth generation EGFR inhibitor designed to be irreversible (covalent) and brain-penetrant, and is unique in that it targets a family of driver mutations in addition to acquired resistance mutations arising from the use of third generation EGFR inhibitors to treat EGFR-positive NSCLC.
• In April 2022, Black Diamond dosed the first patient in its Phase 1 global clinical trial of BDTX-1535 for the treatment of NSCLC, including in patients with brain metastases, and GBM. The dose-escalation portion of the Phase 1 clinical trial is actively recruiting and enrolling patients, and the Company remains on track to provide a clinical update on BDTX-1535 in the second half of 2023.
• In October 2022, Black Diamond presented two posters at the 34th European Organisation for Research and Treatment of Cancer—National Cancer Institute—American Association for Cancer Research (EORTC-NCI-AACR) Symposium in Barcelona, Spain, with new preclinical data. The Company detailed anti-tumor activity of BDTX-1535 in preclinical models and highlighted that BDTX-1535 is designed using Black Diamond’s proprietary MAP drug discovery engine to target EGFR mutations of both NSCLC and GBM. Black Diamond also showcased BDTX-1535’s ability to achieve potent anti-tumor activity against EGFR alterations and amplification across preclinical models of NSCLC classical driver, intrinsic resistance and acquired resistance EGFR mutations and GBM, including intercranial patient derived xenograft models.
  

BDTX-4933:

• BDTX-4933 is designed as a brain-penetrant, small molecule MasterKey reversible oral inhibitor of oncogenic BRAF Class I, II and III active RAF dimers promoted by upstream oncogenic alterations expressed by human cancers, while also avoiding paradoxical activation.
• In the first quarter of 2023, Black Diamond received allowance of its IND application from the FDA. The Company expects to initiate a Phase 1 clinical trial of BDTX-4933 in patients with tumors harboring all-class BRAF or RAS mutations in the first half of 2023.
• In October 2022, Black Diamond presented a poster at the 34th EORTC-NCI-AACR Symposium highlighting preclinical data showing BDTX-4933 to be a brain-penetrant RAF MasterKey inhibitor active against tumors that are driven by a Class I, II, or III BRAF mutation, as well as by other oncogenic RAS pathway alterations that promote constitutive RAF dimer activation. BDTX-4933 demonstrated potent, on-target inhibition of the RAF-MEK-ERK signaling pathway and anti-tumor activity in multiple preclinical models, including intracranial tumor models.
  

Discovery-Stage Pipeline and MAP Drug Discovery Engine:

• Black Diamond continues to leverage its MAP drug discovery engine to advance its discovery-stage pipeline to bring therapies to underserved patients. Black Diamond anticipates progressing its fibroblast growth factor receptor (FGFR) program towards development candidate nomination and nomination of a development candidate against an undisclosed target in 2023.
  

Corporate:

• In June 2022, Black Diamond appointed Sergey Yurasov, M.D., Ph.D., as its Chief Medical Officer, bringing over 25 years of oncology drug development experience and regulatory expertise.
• In December 2022, Black Diamond announced that existing board member, Mark Velleca, M.D., Ph.D., was appointed to succeed Robert (Bob) A. Ingram as the Chairman of the Board of Directors.
• In December 2022, Black Diamond announced the spinout of Launchpad Therapeutics, Inc. (Launchpad), an antibody-focused precision oncology company incorporating Black Diamond’s undisclosed early discovery stage antibody programs enabled by the MAP drug discovery engine. In conjunction with the transaction, a $30 million Series A financing was co-led by Versant Ventures and New Enterprise Associates (NEA) to fund discovery and development activities of the new company. Black Diamond retains a minority equity interest in Launchpad to enable further value creation.
  

Financial Highlights

• Cash Position: Black Diamond ended 2022 with approximately $122.8 million in cash, cash equivalents, and investments compared to $209.8 million as of December 31, 2021. Net cash used in operations was $85.1 million for the year ended December 31, 2022 compared to $100.1 million for the year ended December 31, 2021.
• Research and Development Expenses: Research and development (R&D) expenses were $14.6 million for the fourth quarter of 2022, compared to $19.7 million for the same period in 2021. Research and development expenses were $64.4 million for the year ended December 31, 2022, compared to $96.8 million for the year ended December 31, 2021. The decrease in R&D expenses was primarily due to reduced clinical trial activities stemming from the discontinuation of the development of BDTX-189 to focus on upcoming milestones for our pipeline programs, BDTX-1535 and BDTX-4933.
• General and Administrative Expenses: General and administrative (G&A) expenses were $7.2 million for the fourth quarter of 2022, compared to $6.4 million for the same period in 2021, and $28.4 million for the year ended December 31, 2022, compared to $30.0 million for the year ended December 31, 2021. 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 2022 was $21.1 million, as compared to $25.9 million for the same period in 2021. Net loss for the year ended December 31, 2022 was $91.2 million compared to $125.6 million for the year ended December 31, 2021.

Financial Guidance

• Black Diamond ended 2022 with approximately $122.8 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 2024.
