GUANGZHOU, China, March 28, 2024 (GLOBE NEWSWIRE) -- Burning Rock Biotech Limited (NASDAQ:BNR, the "Company" or "Burning Rock"))), a company focused on the application of next generation sequencing (NGS) technology in the field of precision oncology, today reported financial results for the three months and the year ended December 31, 2023.

2023 Business Overview and Recent Updates

• Corporate Updates
  • Completed profitability-driven organizational optimization, execution towards profitability well underway
• Early Detection  
  • Following the Breakthrough Device Designation granted by the US Food and Drug Administration (FDA) for our OverC™ Multi-Cancer Detection Blood Test (MCDBT) in January 2023, our OverC™ MCDBT also received the Breakthrough Device Designation by China's National Medical Products Administration (NMPA) in October 2023, making it the only test globally that has received Breakthrough Device Designation from both the FDA and the NMPA.
• Therapy Selection and Minimal Residual Disease (MRD)
  • Precision oncology diagnostics product supports advancement in late-stage breast cancer treatment, with results published in the New England Journal of Medicine in June 2023. The study, CAPItello-291, sponsored by our pharma client AstraZeneca, is a phase 3 trial that assessed the efficacy and safety of Capivasertib–fulvestrant therapy in advanced breast cancer patients with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) cancer whose disease has progressed during or after aromatase inhibitor therapy. The study demonstrates that Capivasertib–fulvestrant combination therapy results in significantly longer progression-free survival than treatment with fulvestrant alone.
• Pharma Services
  • New companion diagnostics (CDx) development for breast and prostatic cancer announced with AstraZeneca in China.
  • Entered into a Master Service Agreement in Oncology Companion Diagnostics (CDx) with Boehringer Ingelheim, focusing on advancing the clinical trials related to Boehringer Ingelheim's MDM2-p53 antagonist, brigimadlin (BI 907828), and the development of CDx products in China.

Non-GAAP Measures

In evaluating the business, the company considers and uses non-GAAP measures, such as non-GAAP gross profit and non-GAAP gross margin, as supplemental measures to review and assess operating performance. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The company defines non-GAAP gross profit as gross profit excluding depreciation and amortization. The company defines non-GAAP gross margin as gross margin excluding depreciation and amortization.

The company presents these non-GAAP financial measures because they are used by management to evaluate operating performance and formulate business plans. The company believe non-GAAP gross profit and non-GAAP gross margin excluding non-cash impact of depreciation and amortization reflect the company's ongoing business operations in a manner that allows more meaningful period-to-period comparisons.
