AMG 133 functionally inhibits GIP signalling through human and cynomolgus monkey GIPR with similar potency (half maximal inhibitory concentration (IC 50 ) of 42.4 nM and 26.5 nM, respectively), whereas it has more than 20-fold lower potency for inhibition of GIP signalling through rat GIPR (IC 50 = 822 nM) and did not fully antagonize mouse GIPR with concentrations of up to 3 M
Research suggests that it enhances fibroblast migration, improves cellular survival under stress, and promotes collagen synthesis to support the repair of connective tissue structures
A compounded injection with three components therefore requires three NDC entries on the claim
Tirzepatide's added GIP activity is thought to drive the larger effect on top of the shared GLP-1 pathway though weight loss is only one part of the picture, and semaglutide still has the longer cardiovascular-outcomes track record (more on that below)
