Head-to-head evidence
guselkumab vs tildrakizumab
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

guselkumab · Tremfya

NCT02203032 · Phase 3 · completed
In patients who had not responded well enough to ustekinumab, switching to guselkumab under randomized, blinded conditions produced significantly more visits with clear or almost-clear skin than staying on ustekinumab, a clinically meaningful and statistically significant result in a study designed and blinded to make that comparison fairly.
Next expected readout: December 2026 · NCT05004727 (registry estimate)
tildrakizumab · Ilumya
Marketed by Sun Pharmaceutical Industries
NCT01729754 · Phase 3 · completed
This was a large, randomized, quadruple-blind, placebo- and active-controlled Phase 3 trial (N=1,090) in moderate-to-severe plaque psoriasis. The primary efficacy endpoints, PASI-75 and PGA clear/minimal at Week 12, were both statistically significant in favor of tildrakizumab 200 mg and 100 mg compared with placebo (p<0.001). The strong design and positive primary results provide high-quality evidence of treatment benefit.
Next expected readout: September 2028 · NCT05390515 (registry estimate)
Psoriatic Arthritis
Shared mechanism: IL-23 p19 · full Psoriatic Arthritis pipeline
guselkumab · Tremfya
Marketed by Johnson & Johnson
No graded featured trial for this indication yet; the grade above reflects that absence, not a judgment.
Next expected readout: April 2027 · NCT04929210 (registry estimate)
tildrakizumab · Ilumya
Marketed by Sun Pharmaceutical Industries
NCT04314544 · Phase 3 · completed
The study randomized 508 participants to tildrakizumab or placebo, with outcome assessors masked, and used the clinical ACR20 response as its primary endpoint. However, no results are posted, so whether the primary endpoint was met or missed is unknown.
Next expected readout: December 2028 · NCT04991116 (registry estimate)
