Inhibrx Biosciences Reports Third Quarter 2024 Financial Results

SAN DIEGO, Nov. 14, 2024 /PRNewswire/ -- Inhibrx Biosciences, Inc. (Nasdaq: INBX) (“Inhibrx Biosciences” or the “Company”) today reported financial results for the third quarter of 2024. 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 Biosciences business in May 2024, the biopharmaceutical company now has two programs in ongoing clinical trials, with data readouts for each expected within the next 12 months. 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.

Financial Results

• Cash and Cash Equivalents. As of September 30, 2024, Inhibrx Biosciences had cash and cash equivalents of $196.3 million, compared to $226.9 million as of June 30, 2024. Cash outflows in the period primarily consisted of payments for its ongoing operations, including payments made to its third party contract development and manufacturing organizations (“CDMOs”) and contract research organizations (“CROs”) in support of the Company’s ongoing clinical trials.
• R&D Expense. Research and development expenses were $38.9 million during the third quarter of 2024, compared to $38.1 million during the third quarter of 2023. The increase in research and development expenses was primarily due to:
  • an increase in clinical trial expenses due to the expansion of the Company’s ongoing registration-enabling Phase 2 trial for ozekibart (INBRX-109) for the treatment of unresectable or metastatic conventional chondrosarcoma. Clinical trial expenses also increased as a result of the expansion of the INBRX-106 Phase 1/2 trial and the initiation of the Phase 2/3 trial in head and neck squamous cell carcinoma, including expenses for in-house clinical trial support;
  • offset in part by a decrease in stock option expense as a result of fewer stock options outstanding in the current period under the Company’s new 2024 Omnibus Incentive Plan (the “2024 Plan”) following the termination of its prior plan in connection with the spin-off.
• G&A Expense. General and administrative expenses were $7.9 million during each of the third quarters of 2024 and 2023. The composition of general and administrative expenses fluctuated due to:
  • a decrease in stock option expense as a result of fewer stock options outstanding in the current period under the 2024 Plan following the termination of its prior plan in connection with the spin-off;
  • offset by an increase in professional service expenses related to legal and accounting services to support general corporate and intellectual property matters as well as legal proceedings.
• Other Income (Expense). Other income was $2.9 million during the third quarter of 2024, compared to other expense of $6.0 million during the third quarter of 2023. Following the Company’s spin-off transaction in the second quarter of 2024, the Company no longer has any outstanding third-party debt, and therefore did not incur any interest expense during the period. Other income consists of interest earned on the Company’s sweep and money market account balances.
• Net Loss. Net loss was $43.9 million during the third quarter of 2024, or $2.84 per share, basic and diluted, compared to a net loss of $51.8 million during the third quarter of 2023, or $4.39 per share, basic and diluted.
