AbbVie’s Humira® follow on Rinvoq® may face questions on class safety

Pharmaceutical Technology reported AbbVie’s intended Humira® follow on Rinvoq® (upadacitinib) may face questions on class safety after a safety signal emerged in a postmarketing trial of Pfizer’s Xeljanz® (tofacitinib). Tofacitinib and upadacitinib are both JAK inhibitors, and this safety signal could hamper the movement to JAK inhibitors.
