What Taspoglutide is
A once-weekly GLP-1 analogue that beat exenatide and sitagliptin on HbA1c in phase 3 and was halted in 2010 anyway. Its sponsor recorded the reason on the trial registry: high discontinuation rates mainly due to gastrointestinal tolerability and a risk mitigation plan for hypersensitivity reactions. Anti-drug antibodies were found in 46 to 49 percent of participants.
Taspoglutide is a synthetic analogue of human GLP-1 developed by Ipsen (BIM-51077) and licensed to Roche (R1583) for once-weekly subcutaneous injection in type 2 diabetes. It went into a phase 3 programme, T-emerge, of eight trials that randomised more than 6,000 people, and it is the most fully documented failure in the GLP-1 class: a drug that met its efficacy endpoints and was stopped for how people tolerated it.
Mechanism: 6 kg over 24 weeks. Its distinguishing property was pharmaceutical rather than pharmacological: it was formulated as a sustained-release weekly injection, one of the first in the class.
Regulatory history: Never approved. Phase 3 programme halted in 2010; ClinicalTrials.gov NCT01051011 records termination for high discontinuation rates mainly due to GI tolerability and a risk mitigation plan for hypersensitivity reactions. No marketing application located.
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
