About INBX
Inhibrx Biosciences, Inc. is a clinical-stage biopharmaceutical company focused on developing a broad pipeline of novel biologic therapeutic candidates. The Company utilizes diverse methods of protein engineering to address the specific requirements of complex target and disease biology, including its proprietary protein engineering platforms. Its clinical pipeline of therapeutic candidates includes ozekibart (INBRX-109) and INBRX-106. INBRX-109 is a tetravalent agonist of death receptor 5 (DR5) that it designed with its proprietary single domain antibody (sdAb) platform to drive cancer-selective programmed cell death and to maximize potency while minimizing on-target liver toxicity arising from hepatocyte apoptosis. INBRX-106 is a hexavalent OX40 agonist which is being investigated as a single agent and in combination with KEYTRUDA (pembrolizumab), a PD-1 blocking checkpoint inhibitor, in patients with locally advanced or metastatic solid tumors.

Inhibrx Biosciences Reports Promising Interim Results for Ozekibart in Colorectal Cancer
- Clinical Trial Results: Inhibrx's Phase 1/2 study of Ozekibart (INBRX-109) combined with FOLFIRI shows a 20% objective response rate among 45 evaluable patients, significantly higher than the 1-6% seen with current standard therapies, indicating the drug's potential in late-stage colorectal cancer.
- Disease Control Rate: The overall disease control rate reached 87%, with nearly half of the responses lasting over six months, underscoring Ozekibart's effectiveness in stabilizing tumor growth, particularly in patients with limited treatment options.
- Safety Profile: The safety findings indicate a manageable side effect profile, with common adverse effects such as diarrhea, fatigue, and nausea generally mild to moderate, and importantly, no significant liver toxicity was observed despite most patients having liver metastases at baseline.
- Future Plans: Inhibrx plans to meet with the U.S. FDA later this year to discuss advancing Ozekibart into a first-line registrational trial for colorectal cancer, while also exploring accelerated pathways for fourth-line CRC and refractory Ewing sarcoma.
