TREMFYA is backed by rigorous clinical programs and experience1-3
15+ years
of combined clinical research†
4
indications
including plaque psoriasis, psoriatic arthritis, Crohn’s disease, and ulcerative colitis (UC)‡
>1300
patients assessed in Crohn’s disease

In GALAXI, 27 patients who did not meet SES-CD criteria were removed from the primary efficacy analysis but were included in the all-treated safety set. The STELARA column includes subjects randomized to STELARA and events from placebo subjects after crossing over to STELARA at Week 12 up to dose adjustment.
*Week 96 was defined as 2 years. Week 144 was defined as 3 years.
†Includes events for subjects who dose adjusted up to the timepoint of dose adjustment, and all events through Week 144 for subjects who never dose adjusted.
‡Includes all placebo subjects excluding data after a subject is rescued with guselkumab.
§The STELARA group includes patients randomized to STELARA and events from placebo subjects after crossing over to STELARA at Week 12 up to dose adjustment.
||The placebo group contains all events for the randomized placebo group through Week 12. After Week 12, only the events from subjects who remained on placebo are included.
¶Infections are based on MedDRA system organ class Infections and Infestations.
#Reported through Week 12. Non-suicidal gunshot wound considered by investigator to be not related to study intervention.
**Reported through Week 144. Coronary artery arteriosclerosis considered by investigator to be not related to study intervention.
