Claims

1. A method of treating a metabolic/endocrine disorder in a patient, comprising administering an albumin fusion protein comprising two or more tandemly oriented GLP-1 polypeptides, wherein (i) said GLP-1 polypeptides are selected from wild-type GLP-1, GLP-1 fragments, and GLP-1 variants, fused to albumin comprising the amino acid sequence of SEQ ID NO:

1038, an albumin fragment, or albumin variant thereof, (ii) said albumin fragment or albumin variant increases the serum plasma half-life of the GLP-1 polypeptides, and (iii) said fusion protein has GLP-1 activity.

2. The method of claim 1, wherein said tandemly oriented GLP-1 polypeptides are selected from wild type GLP-1 sequences.
