- Research and development expenses were $25.3 million during the fourth quarter of 2025 as compared to $33.4 million during the fourth quarter of 2024. This decrease during the fourth quarter of 2025 was primarily due to a decrease in expense related to lower clinical trial costs in our ozekibart registration-enabling trial for the treatment of unresectable or metastatic conventional chondrosarcoma as the trial approached completion of enrollment ahead of our data readout in October 2025, as well as a decrease in contract manufacturing expenses;
- Research and development expenses were $113.0 million during the fiscal year 2025 as compared to $203.7 million during the fiscal year 2024. This decrease during the fiscal year 2025 was primarily due to the following factors:
- a decrease in clinical trial expense primarily related to lower clinical trial costs in our ozekibart registration-enabling trial for the treatment of unresectable or metastatic conventional chondrosarcoma as discussed above;
- a decrease in contract manufacturing expense primarily attributable to decreased expenses incurred at our contract development and manufacturing organizations for our ozekibart program and INBRX-106 program, as well as decreased expenses following the 101 Transaction; and
- increased personnel-related expense during the fiscal year 2024 related to the recognition of $25.9 million upon the acceleration of outstanding options in connection with the closing of the 101 Transaction.
- General and administrative expenses were $5.6 million during the fourth quarter of 2025, compared to $16.7 million during the fourth quarter of 2024. This decrease during the fourth quarter of 2025 was primarily due to an increase in legal services incurred in the prior period in connection with legal proceedings, which have since concluded, finding the Company not liable for damages.
- General and administrative expenses were $23.3 million during the fiscal year 2025, compared to $127.9 million during the fiscal year 2024. This decrease during the fiscal year 2025 was primarily due to the following factors:
- one-time expenses incurred during the fiscal year 2024 related to the 101 Transaction, including $68.1 million of legal, advisory, and consulting services, and the recognition of $15.2 million in stock option expense upon the acceleration of outstanding options in connection with the closing of the 101 Transaction; and
- increased expense during the fiscal year 2024 related to legal services incurred in connection with the Company’s legal proceedings as discussed above.
- Other expense was $1.9 million during the fourth quarter of 2025, compared to other income of $2.1 million during the fourth 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 fourth quarter of 2024, the Company did not incur any interest expense following the extinguishment of all outstanding debt in connection with the 101 Transaction.
- Other expense was $5.0 million during the fiscal year 2025, compared to other income of $2.0 billion during the fiscal year 2024. Other expense in the current period consisted of $12.2 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 earned on the Company’s sweep and money market account balances. During the fiscal year ended 2024, as noted above, other income also included the gain recorded in connection with the completion of the 101 Transaction. This gain consisted of (i) the consideration paid by the Acquirer for all outstanding common stock, warrants, and stock options, (ii) the extinguishment of the Company’s outstanding debt which was assumed by the Acquirer, (iii) assets and liabilities related to the Inhibrx 101 Business, which were assumed by the Acquirer, and (iv) transaction costs paid for by the Acquirer.
