The company’s platform has been used to create multifunctional proteins and antibody-based therapies designed to address targets that may be difficult to treat with conventional drugs. Its leading program was INBRX-101, an engineered recombinant human alpha-1 antitrypsin therapy developed for patients with alpha-1 antitrypsin deficiency-associated lung disease. Inhibrx also advanced additional investigational therapies, including INBRX-109, an antibody-based treatment candidate studied in oncology. These products have been evaluated through clinical development programs rather than commercialized as approved medicines by the company. Inhibrx was founded in 2010 and was based in La Jolla, California. In 2024, Sanofi completed its acquisition of Inhibrx, gaining rights to the company’s principal programs, including INBRX-101. The company’s development activities and clinical programs have been directed primarily toward patients in the United States and other international markets through global research and clinical-trial efforts.AI Generated.
