SAN DIEGO, Aug. 13, 2025 /PRNewswire/ -- Inhibrx Biosciences, Inc. (NASDAQ:INBX) ("Inhibrx" or the "Company") today reported financial results for the second 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, 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

The ozekibart (INBRX-109) registration-enabling Phase 2 trial in unresectable or metastatic conventional chondrosarcoma completed full enrollment in July 2025. The completion of 151 progression free survival events are required to unblind the study. The Company expects to announce these results by late October 2025. The Company plans to announce interim data from the Ewing sarcoma and colorectal cancer expansion cohorts at that time as well.
Initial Phase 2 data from the INBRX-106 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, as well as interim data from the Phase 1/2 checkpoint inhibitor refractory or relapsed non-small cell lung cancer trial.

Financial Results

Cash and Cash Equivalents. As of June 30, 2025, Inhibrx had cash and cash equivalents of $186.6 million, as compared to $216.5 million as of March 31, 2025.
Revenue. Revenue was $1.3 million during the second quarter of 2025, as compared to $0.1 million during the second quarter of 2024. The revenue recognized in the first quarter of 2025 was due to the completion of Inhibrx's performance obligations under a license and assignment agreement with Scithera, Inc. The revenue recognized in the second quarter of 2024 was related to an option and license agreement with Regeneron Pharmaceuticals, Inc. and was recognized following the grant of a six-month extension of the option term for one of the selected programs.
R&D Expense. Research and development expenses were $22.3 million for the second quarter of 2025, as compared to $67.6 million for the second quarter of 2024. The decrease was primarily related to expenses in 2024 that did not recur in 2025, such as clinical trial and contract manufacturing activities under the INBRX‑101 program that were eliminated following the 101 Transaction, as well as additional stock option expense incurred upon acceleration of all unvested stock options as part of the 101 Transaction. Additionally, 2024 included other non-recurring expenses including sponsored research, preclinical activities, and purchases of bulk raw materials and lab supplies.
G&A Expense. General and administrative expenses were $6.4 million during the second quarter of 2025, compared to $93.4 million during the second quarter of 2024. The decrease was primarily related to 101 Transaction expenses in 2024 that did not recur in 2025, including legal, advisory, and consulting services, U.S. Securities and Exchange Commission ("SEC") filing fees, and additional stock option expense incurred upon acceleration of all unvested stock options as part of the 101 Transaction.
Other Income (Expense). Other expense was $1.3 million during the second quarter of 2025, as compared to other income of $2.0 billion during the second quarter of 2024. The decrease was primarily related to the $2.0 billion gain recorded in connection with the completion of the 101 Transaction in the second quarter of 2024. Additionally, interest expense decreased relative to the outstanding debt balance in each period and was offset in part by interest income earned on the Company's sweep and money market account balances in each period.
Net Income (Loss). Net loss was $28.7 million during the second quarter of 2025, or $1.85 per share, basic and diluted, as compared to a net income of $1.9 billion during the second quarter of 2024, or earnings per share of $127.10, basic and $125.48, diluted. The decrease was primarily related to the $2.0 billion gain recorded in connection with the completion of the 101 Transaction in the second quarter of 2024, offset in both periods by operational losses.
