Chondrosarcoma is an orphan bone cancer with approximately 2,800 new patients diagnosed annually in the United States and the European Union. There are currently no systemic therapies approved for the treatment of chondrosarcoma.
INBRX-109 is a precision-engineered, tetravalent death receptor 5 (DR5) agonist antibody designed to exploit the tumor-biased cell death induced by DR5 signaling.
In January 2021, the FDA granted Fast Track designation to INBRX-109 for the treatment of patients with unresectable or metastatic conventional chondrosarcoma. Further, in December 2021, FDA granted Orphan Drug Designation to INBRX-109 for this indication.
In November 2021, Inhibrx provided updated results from its ongoing Phase 1 clinical trial evaluating the efficacy and safety of INBRX-109 in patients with conventional chondrosarcoma. Preliminary disease control was observed in 16 of the 18 evaluable patients (89%) measured by RECISTv1.1, with two of the 18 achieving partial responses (11%). Based on preliminary results of the ongoing Phase 1 trial, the median progression-free survival (PFS) is 7.4 months, and the median overall survival has not been reached. Three patients have exceeded 61 weeks on treatment with INBRX-109, with 77 weeks being the longest duration of stable disease observed to date.
In June 2021, Inhibrx initiated a randomized, blinded, placebo-controlled, potentially registration-enabling Phase 2 trial of INBRX-109 in conventional chondrosarcoma. The trial will be conducted at approximately 51 sites within eight countries, with 30 of those sites in the United States.
