In the stage 3 program our company are actually targeting precisely the populace where our team saw a more powerful indicator in phase 2," Brindicci claimed in an interview.Unlike other anti-IL-33 antibodies, tozorakimab possesses a dual mechanism of action that not just prevents interleukin-33 signaling by means of the RAGE/EGFR process but additionally influences a distinct ST2 receptor path associated with inflammation, Brindicci described."
