Open the CIPO recordAbstract From the Canadian patent
The present invention concerns fusion of Fc domains with biologically active peptides and a process for preparing pharmaceutical agents using biologically active peptides. In this invention, pharmacologically active compounds are prepared by a process comprising: a) selecting at least one peptide that modulates the activity of a protein of interest; and b) preparing a pharmacologic agent comprising an Fc domain covalently linked to at least one amino acid of the selected peptide. Linkage to the vehicle increases the halflife of the peptide, which otherwise would be quickly degraded in vivo. The preferred vehicle is an Fc domain. The peptide can be selected for example, by phage …

Why it's free to use
- Filed May 2, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 2, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
