Trial Outcomes & Findings for VTX002 Versus Placebo for the Treatment of Moderately to Severely Active Ulcerative Colitis (NCT NCT05156125)
NCT ID: NCT05156125
Last Updated: 2024-11-13
Results Overview
The percentage of participants with clinical remission at Week 13. Clinical remission was based on the modified Mayo score (MMS), which is a composite score of participant-reported symptoms and endoscopies which were assessed by a central reader. Clinical remission was defined as stool frequency (SF) subscore = 0 or 1, rectal bleeding (RB) subscore = 0, and endoscopic subscore (ES) ≤ 1 (excluding friability). Each component subscore ranged from 0 to 3 and total score range of the MMS was from 0 to 9, with higher scores indicating more severe disease.

PRIMARY outcome
Timeframe: Day 1 of Induction treatment period to Week 13Population: Full Analysis Set - Baseline Modified Mayo Score 5-9
The percentage of participants with clinical remission at Week 13. Clinical remission was based on the modified Mayo score (MMS), which is a composite score of participant-reported symptoms and endoscopies which were assessed by a central reader. Clinical remission was defined as stool frequency (SF) subscore = 0 or 1, rectal bleeding (RB) subscore = 0, and endoscopic subscore (ES) ≤ 1 (excluding friability). Each component subscore ranged from 0 to 3 and total score range of the MMS was from 0 to 9, with higher scores indicating more severe disease.

Timeframe: Day 1 of Induction Treatment Period to Week 13Population: Full Analysis Set - Baseline MMS 5 to 9
The percentage of participants with endoscopic improvement at Week 13. Endoscopic improvement was assessed from endoscopies assessed by a central reader. Endoscopic improvement was defined as ES ≤ 1 (excluding friability). The ES ranged from 0 to 3 (where 0 = normal/inactive disease and 3 = severe disease).

Timeframe: Day 1 of Induction Treatment Period to Week 13Population: Full analysis set - Baseline MMS 5 to 9
The percentage of participants with symptomatic remission at Week 13. Symptomatic remission was measured using participant-reported symptoms and was defined as SF subscore = 0 or 1 and RB subscore = 0. The SF subscore ranged from 0 to 3 (where 0 = normal number of stools and 3 = at least 5 stools more than normal) and RB subscore ranged from 0 to 3 (where 0 = no blood and 3 = blood alone passes). Higher scores indicate more severe disease.

SECONDARY outcome
Timeframe: Day 1 of Induction Treatment Period to Week 13Population: Full analysis set - Baseline MMS 5 to 9
The percentage of participants with histologic remission at Week 13. Histologic remission was assessed using the Geboes Index score and defined for this outcome measure as a Geboes score \< 2.0. The Geboes score grading system is a validated score for evaluating histologic disease activity in ulcerative colitis and is graded on a scale of 0 to 5. A higher Geboes score indicates more severe disease.
