Last reviewed: November 16, 2025 Routine administration of all age-appropriate doses of vaccines at the same visit, also known as coadministration, is acceptable for children, adolescents, and adults if there are no contraindications at the time of the healthcare visit
Three different mechanisms (gene expression, angiogenesis, cell migration) engaging three complementary biological pathways
The critical design decisions included: GIP backbone selection : Starting from GIP rather than GLP-1, as GIP naturally has weak cross-reactivity with GLP-1R, providing a scaffold for optimization Aib2 substitution : Replacing Ala2 with alpha-aminoisobutyric acid for DPP-4 resistance (identical strategy to semaglutide) C-terminal extension : Adding a GGPSSGAPPPS (Gly-Gly-Pro-Ser-Ser-Gly-Ala-Pro-Pro-Pro-Ser) 11-residue C-terminal extension that enhances GLP-1R binding C-20 fatty diacid acylation : Attaching an eicosanedioic acid (C-20 diacid) at Lys20 via a Glu-2xOEG linker for albumin binding The resulting molecule exhibits approximately 5:1 selectivity for GIPR over GLP-1R it is a full GIPR agonist and a partial GLP-1R agonist, yet clinically achieves superior outcomes to selective full GLP-1R agonists [7]
