Inhibrx Biosciences provided updated interim data from its Phase 1/2 study evaluating its treatment for colorectal cancer.
The biopharmaceutical company on Tuesday said its study showed an objective response rate of 20% per RECIST v1.1 criteria, meaning a fifth of the patients had a complete or partial response to the treatment.
The study evaluated the company's ozekibart treatment in combination with FOLFIRI in patients with locally advanced or metastatic, unresectable colorectal cancer. Ozekibart is an antibody treatment designed to kill cancer cells.
The company also said 42% of the trial's patients remained progression-free at the 6-month landmark.
The overall disease control rate was 87%, the company said.
The company plans to meet with the Food and Drug Administration in the second half of 2026 to discuss plans to start a first-line registrational trial. In April, the company plans to submit a Biologics License Applicataion to the FDA for ozekibart in conventional chondrosarcoma.
The FDA previously granted Fast Track designation to ozekibart in 2021.
