TREMFYA® (Guselkumab) Long-Term Data Show Sustained Clinical and Endoscopic Remission in Ulcerative Colitis Through 3 Years

Johnson & Johnson's 3-year data show over 80% of adults with moderate to severe ulcerative colitis achieved clinical remission with TREMFYA, supporting durable disease control.

  • Johnson & Johnson announced Week 140 QUASAR LTE results showing TREMFYA maintained clinical remission of 80.8%, as the Feb. 21, 2026 press release said.
  • The QUASAR program randomized Phase 2b/3 trials used IV induction at Weeks 0, 4 and 8, followed by SC maintenance regimens for adults with ulcerative colitis.
  • Analysis used nonresponder-imputation and as-observed methods to assess durability of response, including 78.6% achieving histo-endoscopic mucosal improvement and 89% completing treatment through Week 140.
  • Regulatorily, TREMFYA is already approved in key jurisdictions and endoscopic remission is linked to fewer flare-ups and lower steroid or surgery needs, Johnson & Johnson said.
  • Some mechanistic findings are limited to in vitro studies and prescribers should check patients for infections and TB before starting TREMFYA because Dr. Laurent Peyrin‑Biroulet is listed as a paid consultant for Johnson & Johnson.
