About Oncurious

ONCURIOUS NV is a Belgium-based biotech company focused on developing innovative oncology treatments derived from a series of promising new targets that are designed to enhance T cell activity and migration and infiltration into resistant tumour sites, boosting the response to immunotherapy in the large numbers of patients who respond sub-optimally to existing treatment.

Oncurious is working on a series of novel immuno-modulatory targets offering the potential to overcome tumor resistance mechanisms, which current immune checkpoint inhibitors cannot address, and thereby significantly enhancing the responses to immunotherapy across multiple tumor types. The team has discovered a potent and diverse panel of leads targeting human CCR8 and is entering the final stage of preclinical candidate selection.

Oncurious is majority owned by Oxurion NV (Euronext Brussels: OXUR), a biopharmaceutical company developing next generation standard ophthalmic therapies designed to better preserve vision in patients with retinal vascular disorders, and VIB. Oncurious notes that BioInvent AB contributed to the initial stages of the trial, holding some co-rights to the project.
