Item 2.02. Results of Operations and Financial Condition.
On December 3, 2025, Black Diamond Therapeutics, Inc. (the “Company”) issued a press release titled “Black Diamond Therapeutics Announces Preliminary Phase 2 Data for Silevertinib in 1L NSCLC and Plans for a Phase 2 Trial of Silevertinib in GBM” and posted an updated corporate presentation to its website at https://investors.blackdiamondtherapeutics.com/events-presentations, which press release and presentation included updated financial guidance for September 30, 2025. Specifically, the Company announced that its previously reported cash, cash equivalents and investments of approximately $135.5 million as of September 30, 2025 is now expected to be sufficient to fund its anticipated operating expenses and capital expenditure requirements into the second half of 2028.
The foregoing updated financial guidance is based on management’s current expectations and assumes that the Company funds its Phase 2 trial of silevertinib in newly diagnosed glioblastoma (“GBM”) and that a potential partner funds pivotal development of silevertinib in non-small cell lung cancer (“NSCLC”).

Item 8.01. Other Events.
On December 3, 2025, the Company announced topline data from its Phase 2 trial of silevertinib in 1L NSCLC patients with non-classical epidermal growth factor receptor (“EGFR”) mutations and outlined plans for a randomized Phase 2 trial of silevertinib in patients with newly diagnosed GBM.
Silevertinib Phase 2 1L NSCLC Initial Clinical Results and Program Update
43 frontline NSCLC patients harboring a broad spectrum of 35 distinct non-classical EGFR mutations were enrolled, including 16 patients with brain metastases (seven of whom had measurable central nervous system (“CNS”) target lesions). All patients were enrolled at a 200 mg oral daily dose of silevertinib. Efficacy and safety were assessed with a November 3, 2025 data cutoff; median follow-up time as of this date was 7.2 months and the study remains ongoing.
Key data highlights include:
For the 43 patients enrolled, preliminary efficacy data is as follows:
| · | 25 confirmed partial responses, one confirmed complete response | |
| · | 60% objective response rate (“ORR”) (ORR by RECIST 1.1) | |
| · | 86% CNS ORR (by RANO-BM) | |
| · | 91% disease control rate |
Initial duration of treatment data:
| · | 29 patients remain on therapy (five out of 29 after progression), longest ongoing for >19 months |
Summary of safety data:
| · | No new safety signals observed | |
| · | Adverse events (“AEs”) experienced by a majority of patients include rash, stomatitis, diarrhea and paronychia |
| · | AEs were managed with standard supportive care and dose interruptions/reductions without compromising response depth or durability to date |
The Company expects to present updated results from the Phase 2 NSCLC trial, including duration of response (“DOR”) and progression-free survival (“PFS”) data in both the recurrent (83 patients) and frontline (43 patients) settings, at a medical meeting in the second quarter of 2026. The Company continues to explore potential partnerships to advance silevertinib into pivotal development.
GBM Program Update and Phase 2 Plans
Approximately 50% of patients with GBM present with an oncogenic EGFR alteration that can be targeted by silevertinib; each year approximately 7,000 patients in the U.S. are diagnosed with GBM harboring these EGFR alterations.
Key trial highlights include:
| · | Expected to enroll approximately 150 newly diagnosed patients, randomized to receive temozolomide (“TMZ”) (control arm) or silevertinib + TMZ (experimental arm) | |
| · | Initial focus will be on EGFRvIII-positive patients (approximately 30% of GBM) who are methylguanine methyltransferase-negative (unmethylated) | |
| · | Randomization and treatment will begin after patients have had their surgical resection and radiation | |
| · | Primary endpoint is PFS (RANO by Blinded Independent Committee Review), with an interim analysis; secondary endpoint is overall survival | |
| · | Trial will be governed by an Independent Data Monitoring Committee |
The Company plans to initiate a randomized Phase 2 trial in newly diagnosed GBM patients in the first half of 2026, with preliminary data expected in 2028.
