Abstract: This invention provides a range of translatable messenger UNA (mUNA) molecules. The mUNA molecules can be translated in vitro and in vivo to provide an active polypeptide or protein, or to provide an immunization agent or vaccine component. The mUNA molecules can be used as an active agent to express an active polypeptide or protein in cells or subjects. Among other things, the mUNA molecules are useful in methods for treating rare diseases.

Abstract: This invention provides pharmaceutical compositions containing a UNA oligomer targeted to TTR and a pharmaceutically acceptable carrier. The compositions can be used in methods for treating or preventing TTR-related amyloidosis in a primate. The compositions, upon administering a single dose to the primate, can reduce TTR protein in the primate for a period of days to weeks.
