About Ona Therapeutics
Ona Therapeutics is a Barcelona biopharmaceutical company founded in 2019 as a spinout from the Institute for Research in Biomedicine Barcelona and ICREA. It develops antibody-drug conjugates intended to treat cancers that resist existing therapies. Its discovery approach uses patient-derived biology to identify tumour-specific antigens and epitopes that can carry cytotoxic payloads selectively into cancer cells. The lead program, ONA-255, is being developed initially for breast cancer, while ONA-389 targets colorectal cancer and other pipeline programs address additional solid tumours. Pharmaceutical companies, clinical investigators and ultimately oncology providers are the commercial and development counterparties for its therapies. The company funds research, preclinical work, clinical trials and regulatory development through venture financings and partnerships. Revenue is expected primarily from licensing, collaboration milestones and eventual product economics. Its June 2026 Series B financed clinical development and the transition from a preclinical to a clinical-stage company.
