Biocon Limited announced that Health Canada has granted Notice of Compliance (NOC) for two denosumab biosimilars: Bosaya (biosimilar to Prolia) and Vevzuo (biosimilar to Xgeva) on April 3, 2026.

Approved Formulations

Bosaya received approval as a 60 mg/mL injection for subcutaneous use in a prefilled syringe, matching the most common presentation of reference drug Prolia. Vevzuo was approved in its standard formulation as a biosimilar to Xgeva.

Market Impact and Patient Access

The approval represents a significant milestone for Canadian patients requiring denosumab therapy. Prolia is widely prescribed for postmenopausal osteoporosis and bone loss in cancer patients, while Xgeva treats giant cell tumor of bone and prevents skeletal-related events in cancer patients.

Biosimilars typically offer 20-30% cost savings compared to reference biologics, potentially improving patient access to these critical therapies. The Canadian biosimilar market has grown substantially, with Health Canada maintaining rigorous approval standards requiring demonstration of similarity in quality, safety, and efficacy.

Biocon’s Biosimilar Portfolio

This approval strengthens Biocon’s position in the global biosimilar market. The India-based biopharmaceutical company has established itself as a leading biosimilar developer, with multiple products approved across various therapeutic areas including oncology, diabetes, and autoimmune diseases.

Denosumab biosimilars face complex manufacturing challenges due to the monoclonal antibody’s intricate structure. Successful regulatory approval demonstrates Biocon’s advanced biotechnology capabilities and quality systems meeting international standards.

Next Steps

Biocon will now focus on commercial launch preparations, including pricing negotiations with provincial health authorities and distribution partnerships. The company expects to make both products available to Canadian patients in the coming months, pending final commercial arrangements.
