Inhibrx Reports First Quarter 2025 Financial Results

SAN DIEGO, May 14, 2025 /PRNewswire/ -- Inhibrx Biosciences, Inc. (NASDAQ:INBX) ("Inhibrx" or the "Company") today reported financial results for the first quarter of 2025. Following the completion of the sale of INBRX-101 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, with data readouts for each expected within the current year. Because the spin-off was accounted for as a reverse spin-off, for periods prior to the spin-off, the Company's financial statements are the historical financial statements of the Former Parent.

Upcoming Milestones

• INBRX-109
  • Data from the registration-enabling Phase 2 trial in unresectable or metastatic conventional chondrosarcoma are expected during the third quarter of 2025; and
  • Initial data on the colorectal cancer expansion cohort are anticipated in the third quarter of 2025 with interim data from the Ewing sarcoma expansion cohort expected in the second half of 2025.
• INBRX-106
  • Initial Phase 2 data from the randomized Phase 2/3 trial in head and neck squamous cell carcinoma in combination with KEYTRUDA^® (pembrolizumab) are expected during the fourth quarter of 2025; and
  • Interim data from the Phase 1/2 checkpoint inhibitor refractory or relapsed non-small cell lung cancer are expected during the fourth quarter of 2025.

Financial Results

• Cash and Cash Equivalents. As of March 31, 2025, Inhibrx had cash and cash equivalents of $216.5 million, compared to $152.6 million as of December 31, 2024. The Company's cash balance increased following the receipt of $100.0 million in gross principal in January 2025 under a loan and security agreement (the "2025 Loan Agreement") entered into with Oxford Finance LLC ("Oxford").
• R&D Expense. Research and development expenses were $36.9 million during the first quarter of 2025, compared to $63.9 million during the first quarter of 2024. The decrease in research and development expenses was primarily due to a decrease in clinical trial expenses and contract manufacturing expenses following the spin-off of our INBRX-101 program in the second quarter of 2024.
• G&A Expense. General and administrative expenses were $6.0 million during the first quarter of 2025, compared to $10.0 million during the first quarter of 2024. The decrease in general and administrative expenses was primarily due to:
  • a decrease in non-cash stock option expense as a result of fewer stock options outstanding in the current period under the Company's new 2024 Omnibus Incentive Plan following the termination of its prior plan in connection with the spin-off;
  • a decrease in professional service expenses in the current period as a result of higher legal and accounting services in the prior period to support the spin-off transaction and the conclusion of legal proceedings.
• Other Income (Expense). Other expense was $0.4 million during the first quarter of 2025, compared to other expense of $4.9 million during the first quarter of 2024. Other expense consists of interest expense incurred on the Company's outstanding third-party debt during each period, offset in part by interest income earned on the Company's sweep and money market account balances. The Company incurred less interest expense during the first quarter of 2025 as compared to the first quarter of 2024 due to a lower principal balance under its 2025 Loan Agreement as compared to its prior borrowings with Oxford which were extinguished as a result of the spin-off transaction.
• Net Loss. Net loss was $43.3 million during the first quarter of 2025, or $2.80 per share, basic and diluted, compared to a net loss of $78.7 million during the first quarter of 2024, or $5.77 per share, basic and diluted.
