Inhibrx Reports Second Quarter 2023 Financial Results and Recent Corporate Highlights

SAN DIEGO, Aug. 7, 2023 /PRNewswire/ -- Inhibrx, Inc. (Nasdaq: INBX), or Inhibrx, or the Company, a biopharmaceutical company with four programs in ongoing clinical trials and a strong emerging pipeline, today reported financial results for the second quarter of 2023 and provided an update on recent corporate highlights.

Recent Corporate Highlights

• On May 30, 2023, Inhibrx announced that the U.S. Food and Drug Administration granted Fast Track designation to INBRX-101, an optimized recombinant human AAT-Fc fusion protein, for the treatment of patients with emphysema due to alpha-1 antitrypsin deficiency, or AATD.
• On July 24, 2023, Inhibrx received written scientific advice from the European Medicines Agency, or EMA, which confirmed CT lung densitometry as the established primary regulatory endpoint to support a marketing authorization application in the European Union for the treatment of emphysema secondary to AATD. Inhibrx's delivery of the EMA scientific advice to Chiesi Farmaceutici S.p.A, or Chiesi, triggered Chiesi's 60-day option period window to obtain an exclusive license to develop and commercialize INBRX-101 outside of the United States and Canada.

Financial Results

• Cash and Cash Equivalents. As of June 30, 2023, Inhibrx had cash and cash equivalents of $192.5 million, compared to $273.9 million as of December 31, 2022. The increase in cash outflow during the second quarter of 2023 was a result of the timing of payments made to the Company's contract development and manufacturing organizations, or CDMOs, related to development and manufacturing costs supporting our clinical and preclinical candidates. Additionally, there was an increase in cash outflow during the period upon the initiation of the INBRX-101 registration-enabling trial to the Company's contract research organization, or CRO, partner, as well as the timing of payments associated with the progression of its INBRX-109 Phase 1 combination cohorts and registration-enabling Phase 2 trial for the treatment of unresectable or metastatic conventional chondrosarcoma.
• R&D Expense. Research and development expenses were $34.1 million during the second quarter of 2023, compared to $29.9 million during the second quarter of 2022. During the second quarter of 2023, Inhibrx's clinical trial expenses increased, primarily related to the initiation of the registration-enabling Phase 2 trial for INBRX-101 for the treatment of emphysema due to AATD, as well as the progression of our INBRX-109 registration-enabling Phase 2 trial for the treatment of unresectable or metastatic conventional chondrosarcoma. Personnel-related costs also increased during both periods, partially attributable to an increase in headcount as the Company continues to expand its clinical operations teams, as well as the issuance of additional stock options and the expansion of our bonus eligibility pool in the current year. These increases were offset in part by decreased CMC expenses incurred at our CDMO and CRO partners supporting our clinical and preclinical therapeutic candidates due to the nature of the development and manufacturing activities performed, which reflect the stage-specific needs of our programs during each period.
• G&A Expense. General and administrative expenses were $7.3 million during the second quarter of 2023, compared to $5.4 million during the second quarter of 2022. This overall increase was primarily driven by an increase in additional personnel-related costs in part due to the expansion of the Company's commercial strategy and medical affairs team as well as the issuance of additional stock options and the expansion of our bonus eligibility pool in the current year. In addition, market research and other scientific publication expenses were incurred related to its continued pre-commercialization efforts for INBRX-101 and INBRX-109.
• Net Loss. Net loss was $47.1 million during the second quarter of 2023, or $1.08 per share, compared to $37.7 million during the second quarter of 2022, or $0.97 per share.
