Inhibrx Reports Second Quarter 2022 Financial Results and Recent Corporate Highlights

SAN DIEGO, Aug. 8, 2022 /PRNewswire/ -- Inhibrx, Inc. (Nasdaq: INBX), a biotechnology company with four clinical programs in development and a strong emerging pipeline, today reported financial results for the second quarter of 2022 and provided an update on recent corporate highlights.

Recent Corporate Highlights

• On May 16, 2022, Inhibrx announced topline results from its Phase 1 clinical trial in INBRX-101 showing a favorable safety profile in patients with alpha-1 antitrypsin deficiency, or AATD, and demonstrating the potential to achieve normal functional alpha-1 antritrypsin levels with monthly dosing. The data shows the treatment was well tolerated with no severe or serious adverse events related to the study drug.
• On June 30, 2022, Inhibrx announced completion of its Phase 1 dose escalation of INBRX-105 in combination with Keytruda® and the initiation of Part 4 of the Phase 1 clinical trial.
• On June 30, 2022, Inhibrx announced the receipt of $60.0 million in gross proceeds under its Loan and Security Agreement with Oxford Finance LLC.

Financial Results

• Cash and Cash Equivalents. As of June 30, 2022, Inhibrx had cash and cash equivalents of $176.4 million, compared to $131.3 million as of December 31, 2021.
• R&D Expense. Research and development expenses were $29.9 million during the second quarter of 2022, compared to $17.9 million during the second quarter of 2021. During the period, Inhibrx's clinical trial expenses increased, both for its Phase 1 trials as they continue to progress, including the purchase of Keytruda as used in combination studies in its INBRX-105 trial, as well as its continued expenses related to the INBRX-109 potentially registration-enabling Phase 2 trial which was initiated during the second quarter of 2021. The organization also incurred increased contract manufacturing expenses due to greater production run costs at its contract development and manufacturing organization partners, including drug substance batch manufacturing in preparation for a Phase 2 trial supply and pilot batch production for one of its preclinical candidates. Personnel-related costs also increased during the period, which is attributable to an increase in headcount as Inhibrx continues to expand its clinical operations and technical operations teams.
• G&A Expense. General and administrative expenses were $5.4 million during the second quarter of 2022, compared to $2.9 million during the second quarter of 2021. This overall increase was primarily driven by an increase in additional personnel-related costs due to an increase in headcount as the organization builds out its commercial strategy team. In addition, Inhibrx incurred market research expenses related to its continued pre-commercialization efforts for INBRX-101 and INBRX-109.
• Net Loss. Net loss was $37.7 million during the second quarter of 2022, or $0.97 per share, compared to $20.7 million during the second quarter of 2021, or $0.55 per share.

About the Inhibrx sdAb Platform
Inhibrx utilizes diverse methods of protein engineering in the construction of therapeutic candidates that can address the specific requirements of complex target and disease biology. A key tool for this effort is the Inhibrx proprietary single-domain antibody, or sdAb, platform, which enables the development of therapeutic candidates with attributes superior to other monoclonal antibody and fusion protein approaches. This platform allows the combination of multiple binding units in a single molecule, enabling the creation of therapeutic candidates with defined valency or multiple specificities that can achieve enhanced cell signaling or conditional activation. An additional benefit of this platform is that these optimized, multi-functional entities can be manufactured using the established processes that are commonly used to produce therapeutic proteins.
