Note on Biologic Patents

Matching patents to biologic drugs is far more complicated than for small-molecule drugs.

DrugPatentWatch employs three methods to identify biologic patents:

1. Brand-side disclosures in response to biosimilar applications

These patents were identified from disclosures by the brand-side company, in response to a potential biosimilar seeking to launch. They have a high certainty of blocking biosimilar entry. The expiration dates listed are not estimates — they're expiration dates as indicated by the brand-side company.

2. DrugPatentWatch analysis and brand-side disclosures

These patents were identified from searching drug labels and other general disclosures from the brand-side company. This list may exclude some of the patents which block biosimilar launch, and some of these patents listed may not actually block biosimilar launch. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

3. Patents from broad patent text search

For completeness, these patents were identified by searching the patent literature for mentions of the branded or ingredient name of the drug. Some of these patents protect the original drug, whereas others may protect follow-on inventions or even inventions casually mentioning the drug. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

Market Dynamics and Financial Trajectory for the Biologic Drug: Denosumab

Last updated: July 27, 2025

Introduction

Denosumab, marketed primarily under the brand name Prolia for osteoporosis and Xgeva for skeletal-related events in cancer, is a monoclonal antibody targeting RANKL (Receptor Activator of Nuclear Factor Kappa-Β Ligand). Since its approval in 2010, denosumab has revolutionized the management of bone metabolic disorders. The drug's unique mechanism, competitive positioning, and emerging indications have significantly influenced market dynamics and its financial trajectory. Analyzing these elements provides valuable insights for stakeholders navigating this evolving landscape.

Market Overview

The global biologic drugs market stands at a robust valuation, with osteoporosis treatments forming a substantial segment. The demand for denosumab has grown owing to its efficacy in reducing fracture risk, convenience of subcutaneous administration, and its comparative advantage over bisphosphonates, notably in patients intolerant to oral therapies [1].
