Recent Strategic Developments:

• Spin-off and Merger (May 2024): Inhibrx, Inc. (Former Parent) completed the spin-off of INBRX-101, an optimized, recombinant alpha-1 antitrypsin (AAT) augmentation therapy, into a separate entity. Concurrently, the Former Parent merged with Art Acquisition Sub, Inc., a wholly-owned subsidiary of Aventis Inc. (a Sanofi S.A. subsidiary). As a result, Inhibrx Biosciences, Inc. became a stand-alone, publicly traded company, acquiring assets and liabilities related to its ongoing programs, ozekibart (INBRX-109) and INBRX-106, and its discovery pipeline.
• Ozekibart (INBRX-109) Registrational Trial Success: In October 2025, the ChonDRAgon trial for ozekibart in advanced or metastatic chondrosarcoma met its primary endpoint, demonstrating a statistically significant and clinically meaningful median progression-free survival (PFS). Ozekibart achieved a 52% reduction in the risk of disease progression or death compared to placebo (stratified Hazard Ratio 0.479; 95% CI: 0.33, 0.68); P<0.0001), more than doubling median PFS to 5.52 months versus 2.66 months for placebo.
• Regulatory Filings: Following positive ChonDRAgon trial results, Inhibrx Biosciences, Inc. plans to submit a Biologics License Application (BLA) for ozekibart in chondrosarcoma early in the second quarter of 2026. The company also plans to meet with the FDA in the second half of 2026 to discuss an accelerated approval pathway for ozekibart in Ewing sarcoma, contingent on continued positive response and duration trends.
• INBRX-106 Clinical Advancement: A seamless Phase 2/3 clinical trial for INBRX-106 in combination with KEYTRUDA® (pembrolizumab) as a first-line treatment for locally advanced recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) completed Phase 2 enrollment of 68 patients in the first quarter of 2026. Initial Phase 2 results are expected in the second quarter of 2026, with PFS data anticipated in the fourth quarter of 2026.

Geographic Footprint: Inhibrx Biosciences, Inc.'s corporate headquarters and primary operations are located in La Jolla, California, where it leases approximately 43,000 square feet of laboratory and office space. Clinical trials for its therapeutic candidates are conducted in the United States and globally, with the ChonDRAgon trial for ozekibart enrolling over 200 patients at 68 sites worldwide. The company has also previously formed partnerships in China to access patient populations for clinical trials.
