The invention relates to an agent for the production of a medicament which is used postoperatively after the removal of bone tumours. The inventive agent is produced from a nucleic acid. A sequence known per se for promoting bone growth and a protease inhibitor also known per se are bonded by means of a variable spacer molecule.

The invention is used in medecine, particularly in the specialist field of orthopaedics.

Why it's free to use
- Filed April 18, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 18, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 18, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
