SAN DIEGO, Aug. 13, 2026 /PRNewswire/ -- Inhibrx Biosciences, Inc. (Nasdaq: INBX) ("Inhibrx" or the "Company") today reported financial results for the second quarter of 2026. The biopharmaceutical company has two programs in ongoing clinical trials.

Recent Corporate Highlights and Upcoming Milestones

• Oxford Loan Amendment. In July 2026, the Company entered into a second amendment to the Loan and Security Agreement (Second Amendment) with Oxford Finance LLC (Oxford), which provides for an additional $325.0 million in gross proceeds, (i) $100.0 million of which was funded upon execution of the amendment and (ii) up to an additional $225.0 million which, upon the Company's request and at Oxford's discretion, may be funded in future increments of $50.0 million or more.
• INBRX-106
  • The Company plans to announce progression-free survival (PFS) data from the randomized Phase 2 trial in head and neck squamous cell carcinoma (HNSCC) in combination with pembrolizumab in the third quarter of 2026.

• ozekibart (INBRX-109)
  • During the second quarter of 2026, Inhibrx initiated two additional Phase 1 cohorts in colorectal cancer (CRC): (1) a second line study investigating ozekibart in combination with Folfiri and Avastin, and (2) a third/fourth line study investigating ozekibart in combination with Lonsurf and Avastin. The Company expects to announce interim results from these cohorts during the first quarter of 2027.
  • In June 2026, the U.S. Food and Drug Administration (FDA) accepted for filing the Company's biologics license application (BLA) for the potential approval of ozekibart in conventional chondrosarcoma and assigned a Prescription Drug User Fee Act (PDUFA) goal date of April 14, 2027.
  • The Company plans to meet with the FDA in the fourth quarter of 2026 to discuss plans to initiate a first-line registrational trial in CRC as well as the potential for an accelerated regulatory pathway for ozekibart in fourth-line CRC. 

Financial Results

• Cash and Cash Equivalents. As of June 30, 2026, the Company had cash and cash equivalents of $133.3 million. On July 15, 2026, the Company entered into the Second Amendment to the Loan and Security Agreement with Oxford, and received gross proceeds of $100.0 million. As of August 6, 2026, the Company had cash and cash equivalents of $219.5 million. 

• Revenue. Inhibrx earned $1.3 million of revenue during the second quarter of 2025 related to the Company's completion of the transfer of all licenses, related materials, and know-how under a license and assignment agreement with Scithera, Inc. The Company did not recognize any revenue during the second quarter of 2026.

• R&D Expense. Research and development expenses were $23.9 million for the second quarter of 2026, as compared to $22.3 million for the second quarter of 2025. This increase was primarily related to increases in both clinical trial costs and contract manufacturing expenses as the Company progresses its ongoing clinical trials and begins certain manufacturing activities to supports its filing of the BLA for the potential approval of ozekibart (INBRX-109) in conventional chondrosarcoma. These increases were offset in part by a decrease in personnel-related expenses and clinical consulting expenses.

• G&A Expense. General and administrative expenses were $8.3 million during the second quarter of 2026, compared to $6.4 million during the second quarter of 2025. This increase is primarily related to additional pre-commercialization expenses related to market access, launch and the development of communication materials as the Company prepares for its potential commercialization of ozekibart (INBRX-109) in conventional chondrosarcoma.

• Other Expense, Net. Other expense, net was $4.5 million during the second quarter of 2026, compared to $1.3 million during the second quarter of 2025. The increase is primarily due to higher interest expense on the Company's $175.0 million outstanding loan balance during the second quarter of 2026 as compared to $100.0 million outstanding during the second quarter of 2025. This also reflects a decrease in interest income on the Company's cash and money market balances due to lower average cash balances and a decline in short-term interest rates.

• Net Loss. Net loss was $36.7 million during the second quarter of 2026, or $2.34 per share, basic and diluted, as compared to a net loss of $28.7 million during the second quarter of 2025, or $1.85 per share, basic and diluted.
