Who We Are

Oncternal Therapeutics is a clinical-stage oncology company developing a diverse pipeline of treatments for cancers with critical unmet medical need. Oncternal focuses drug development on promising yet untapped biological pathways implicated in cancer progression.

The pipeline includes cirmtuzumab, a monoclonal antibody in Phase 1/2 development that inhibits the ROR1 receptor in various hematologic cancers; TK-216, a small-molecule in Phase 1 development that inhibits ETS-family oncoproteins, as a treatment for Ewing sarcoma, a rare pediatric cancer; and a CAR-T therapy that targets ROR1 currently in preclinical development as a potential treatment for solid tumors and hematologic cancers.

Based in San Diego, Oncternal is committed to advancing its pipeline rapidly and efficiently to bring patients a new wave of first-in-class cancer treatments.
