Taspoglutide is a pharmaceutical drug, a glucagon-like peptide-1 agonist (GLP-1 agonist), under investigation for treatment of type 2 diabetes being codeveloped by Ipsen and Roche.[1] [2]

Two phase II trials reported it was effective and well tolerated.[3]

Of the eight planned phase III clinical trials of weekly taspoglutide (four against exenatide, sitagliptin, insulin glargine, and pioglitazone), at least five were active in 2009.[4] Preliminary results in early 2010 were favourable.[5] (At least one of the eight planned phase III trials had not started recruiting by end 2009.[6])

In September 2010 Roche halted Phase III clinical trials due to incidences of serious hypersensitivity reactions and gastrointestinal side effects.[7][8]

As of May 2013 no new trials had been registered.[9][needs update]


Taspoglutide is the peptide with the sequence H2N-His-2-methyl-Ala-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-Ser-Tyr-Leu-Glu-Gly-Gln-Ala-Ala-Lys-Glu-Phe-Ile-Ala-Trp-Leu-Val-Lys-2-methyl-Ala-Arg-CONH2.

In other words, it is the 8-(2-methylalanine)-35-(2-methylalanine)-36-L-argininamide derivative of the amino acid sequence 7–36 of human glucagon-like peptide I.


Taspoglutide was a promising Glucagon-like Peptide 1 receptor agonist and Incretin mimetic. The short duration of action was likely its demise.
