SAN DIEGO, May 13, 2021 /PRNewswire/ --InhibRx, Inc. (Nasdaq: INBX), a biotechnology company with four clinical programs in development, today reported financial results for the first quarter of 2021.

"This past quarter, we continued to make significant progress advancing our clinical programs and are on track to deliver data from all four programs later this year," said the Company's Chief Executive Officer, Mark Lappe.

Financial Results

• Cash and Cash Equivalents. As of March 31, 2021, Inhibrx had cash and cash equivalents of $108.0 million, compared to $128.7 million as of December 31, 2020.

• R&D Expense. Research and development expenses were $16.4 million during the first quarter of 2021, compared to $17.0 million during the first quarter of 2020.

• G&A Expense. General and administrative expenses were $3.0 million during the first quarter of 2021, compared to $1.5 million during the first quarter of 2020. This increase was primarily due to an increase in personnel-related costs and other expenses associated with operating as a public company.

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 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.
