What is Albiglutide (Tanzeum)?
Plain language first. The technical label stays, but it never stands alone.Overview
A weekly GLP-1 that was approved, underperformed its rivals, needed mixing before each shot, and was withdrawn worldwide for commercial reasons.
Albiglutide, a GLP-1 receptor agonist consisting of GLP-1 dimer fused to recombinant human albumin, FDA-approved 2014 as Tanzeum and marketed in Europe as Eperzan. Elimination half-life approximately 5 days. GSK announced worldwide withdrawal in 2017 for economic reasons, with supply chain stocks depleted by 2018. Published comparative analysis found lower HbA1c and weight reduction than other agents in the class.
What it's used for
A weekly injected GLP-1 for type 2 diabetes. Withdrawn from the market and no longer available.
How does Albiglutide (Tanzeum) work?
What it does in the body, and where.Albiglutide is worth a page mainly as a correction to the lists that still include it.
- 01GLP-1 fused to albuminThe molecule joins a GLP-1 sequence to human albumin, which is what gave it a half-life of several days and allowed weekly dosing.
- 02It lost on effectiveness and on convenienceA published analysis found it lowered HbA1c and body weight less than other GLP-1 agonists. It also required reconstitution before each injection, which patients disliked.
- 03Withdrawal was commercialGSK announced the worldwide withdrawal in 2017 for economic reasons and remaining supply was gone by 2018. No safety signal drove the decision, which is a meaningful difference from a drug pulled for harm.
Acts on one receptor.
What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.
