About ozekibart (INBRX-109)
Ozekibart is a precision-engineered, tetravalent death receptor 5 (DR5) agonist antibody designed to exploit the tumor-biased cell death induced by DR5 activation. In January 2021, the FDA granted Fast Track designation to ozekibart for the treatment of patients with metastatic or unresectable conventional chondrosarcoma, and, in November 2021, the FDA granted orphan drug designation to ozekibart for chondrosarcoma.

In June 2021, Inhibrx initiated a randomized, blinded, placebo-controlled, registration-enabling Phase 2 trial of ozekibart in metastatic, unresectable conventional chondrosarcoma.

Additionally, in Phase 1/2 trials, Inhibrx is investigating ozekibart in colorectal cancer in combination with FOLFIRI and Ewing sarcoma in combination with irinotecan/temozolomide, as well as other tumor types.
