Watch For Semglee to Be "Interchangeable" With Lantus
Semglee (insulin glargine-yfgn U-100) will be the first "interchangeable" biosimilar.
It was originally approved as a new brand of insulin glargine, not a Lantus generic...and switching required a new Rx.
Now Semglee is both biosimilar to, and interchangeable with, Lantus. Biosimilars have to show similar safety, purity, and potency as the original, or "reference," biologic.
