SAN DIEGO, Nov. 14, 2025 /PRNewswire/ — Inhibrx Biosciences, Inc. (Nasdaq: INBX) (“Inhibrx” or the “Company”) today reported financial results for the third quarter of 2025. Following the completion of the sale of INBRX-101 (the “101 Transaction”) by Inhibrx, Inc. (the “Former Parent”) to Sanofi S.A. and the Former Parent’s concurrent spin-off of the Inhibrx business in May 2024, the biopharmaceutical company now has two programs in ongoing clinical trials.
Recent Corporate Highlights
On October 23, 2025, Inhibrx announced positive topline results from its registrational trial of ozekibart (INBRX-109) in chondrosarcoma and provided an update on its colorectal cancer and Ewing sarcoma expansion cohorts.
Ozekibart met its primary endpoint in chondrosarcoma, demonstrating a statistically significant and clinically meaningful improvement in median progression-free survival compared to placebo.
Key secondary endpoints reinforce the primary benefit, demonstrating meaningful improvements in disease control and patient quality of life.
Inhibrx plans to submit to the U.S. Food and Drug Administration a biologics license application in the second quarter of 2026.
Interim data from expansion cohorts in patients with colorectal cancer and Ewing sarcoma demonstrate high response and disease control rates in difficult-to-treat, heavily pretreated patients.
Financial Results
Cash and Cash Equivalents . As of September 30, 2025, Inhibrx had cash and cash equivalents of $153.1 million, as compared to $186.6 million as of June 30, 2025.
R&D Expense . Research and development expenses were $28.5 million for the third quarter of 2025, as compared to $38.9 million for the third quarter of 2024. The decrease was primarily related to a decrease in process development and manufacturing activities performed by our CDMO partners during the prior year in connection with the Company’s clinical trial for ozekibart (INBRX-109). In addition, personnel-related expenses decreased as a result of a decrease in headcount in the current period.
G&A Expense . General and administrative expenses were $5.3 million during the third quarter of 2025, compared to $7.9 million during the third quarter of 2024. The decrease was primarily related to decreased legal expenses following the conclusion of legal proceedings as well as decreased personnel-related expenses as a result of a decrease in headcount in the current period.
Other Expense. Other expense was $1.4 million during the third quarter of 2025, as compared to other income of $2.9 million during the third quarter of 2024. Other expense in the current period consisted of $3.2 million of interest expense on the Company’s $100.0 million outstanding debt balance, offset in part by other income. Other income during each period consisted of interest income earned on the Company’s sweep and money market account balances. During the third quarter of 2024, the Company did not incur any interest expense following the extinguishment of all outstanding debt in connection with the 101 Transaction.
Net Loss. Net loss was $35.3 million during the third quarter of 2025, or $2.28 per share, basic and diluted, as compared to a net loss of $43.9 million during the third quarter of 2024, or $2.84 per share, basic and diluted.
