Do you want a general overview of the patent landscape for Evenity (romosozumab) or specific details (like patent numbers, expiry dates by region, or which patents are still in force)? I can tailor it once I know what you need.
Here’s a concise overview to get you started:
- What Evenity is
- Evenity is romosozumab, a humanized monoclonal antibody that inhibits sclerostin, developed for osteoporosis and fracture risk reduction.
- Types of patent protection around romosozumab
- Composition-of-matter patents: Cover the romosozumab antibody itself and variants that bind sclerostin.
- Method-of-use patents: Claims for treating osteoporosis, preventing fractures, and related bone diseases using romosozumab or sclerostin inhibitors.
- Formulation and dosing patents: Claims on how the drug is formulated and administered (e.g., monthly 210 mg dosing regimens and related delivery systems).
- Additional patents: Covering manufacturing processes, analytical methods, and potential combinations or sequential therapy (for example, using romosozumab with subsequent antiresorptives like alendronate).
- Regional and regulatory exclusivities
- In the US and EU, there are regulatory protections beyond patents, such as data exclusivity for biologics (e.g., 12 years of data exclusivity in the US for biologics under the BPCIA, with regional variations).
- Patent terms typically run from the earliest non-provisional filing date and can be extended by term adjustments; actual expiry dates vary by patent family and country and may be affected by patent term extensions or litigation outcomes.
- Practical notes
- The patent landscape for romosozumab is complex and regional. New filings, reissues, continuations, or lawsuits can affect status.
- If you’re considering freedom-to-operate, licensing, or due diligence, you’ll want to review the exact patent families in the regions of interest and check current status (active, expired, expired due to settlement, or under litigation).
If you tell me which region (US, EU, Japan, etc.) and whether you want:
- exact patent numbers and families,
- current legal status (active vs expired),
- expected expiry dates or licensing opportunities,
I can pull the latest specifics and summarize them for you.
