Anti-oxMIF
Assets

Unlocking the Potential of Site-Directed Therapies .

The discovery of oxMIF created a unique opportunity for disease-selective targeting. Generated specifically at sites of inflammation and cancer, oxMIF enables therapeutic activity to be focused on diseased tissues. ImmunoOne's oxMIF platform and associated assets provide partners with a differentiated foundation for developing novel therapeutics and diagnostics.

ON104 - Chronic Inflammation

ON104 is a fully human, next-generation monoclonal antibody designed to neutralize oxMIF with precision. Its silenced effector functions eliminate unwanted immune cell activation, while its optimized biophysical and pharmacokinetic profile makes it well suited for the treatment of rheumatoid arthritis, nephritis, and related inflammatory conditions.

ON104 neutralizes the broad, disease-driving activities of oxMIF. Because oxMIF can override the immunosuppressive effects of glucocorticoids, ON104 works in concert with existing immunosuppressant therapies enhancing their effectiveness at the site of disease.

  • Late-stage preclinical asset with a defined clinical development path.
  • Complete development package: master cell bank, scalable fed-batch manufacturing process, and Phase 1 study synopsis.
  • Established safety and translational data: in vitro safety studies, multi-species PK (mouse, rat, dog), and human dose modeling.
  • Preclinical proof-of-concept demonstrated in rheumatoid arthritis and nephritis models.
  • High-dose subcutaneous formulation enabling convenient at-home self-administration via autoinjector.

ON203 - Solid Tumors

ON203 is a fully human, next-generation monoclonal antibody designed to neutralize oxMIF and activate the innate immune response in solid tumors, including antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). Its optimized tumor penetration and pharmacokinetic profile make it well suited for the treatment of colorectal, lung, and other solid tumor indications
