VTX002 Versus Placebo for the Treatment of Moderately to Severely Active Ulcerative Colitis

Phase 2
Active, not recruiting
Conditions
Colitis, Ulcerative
Interventions
Drug: Placebo
Registration Number
NCT05156125
Lead Sponsor
Oppilan Pharma Ltd
Brief Summary

This is a study to understand if taking VTX002 daily as a tablet orally is safe and effective in participants diagnosed with moderate to severe ulcerative colitis (UC). Approximately 189 participants will take VTX002 Dose A, VTX002 Dose B, or matching placebo, once daily.

The study consists of a 28-day Screening Period (to see if a participant qualifies for the study), a 13-week double-blind period (a participant receives either active Dose A, Dose B or Placebo), a Long-Term Extension (LTE) Treatment Period of up to 39 weeks, an Open-Label Extension (OLE) Treatment Period of up to 143 weeks, and a 2-week Follow-Up Period. The maximal duration of treatment including the Induction Period, LTE and OLE will be 36 months.

Detailed Description

This is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of VTX002 in subjects with moderately to severely active UC following daily oral administration of VTX002 as a tablet. Approximately 189 eligible subjects will be randomized in a 1:1:1 ratio to receive VTX002 Dose A, VTX002 Dose B, or matching placebo, once daily (approximately 63 subjects per treatment group).

The study consists of a 28-day Screening Period, a 13-week double-blind Induction Treatment Period (including 7 days of titration followed by 12 weeks of treatment at the assigned dose), a Long-Term Extension (LTE) Treatment Period of up to 39 weeks, an Open-Label Extension (OLE) Treatment Period of up to 143 weeks, and a 2-week Follow-Up Period. The maximal duration of treatment including the Induction Period, LTE and OLE will be 36 months.

Objectives Primary Objective

• Assess the efficacy of VTX002 when administered for 13 weeks on clinical remission

Secondary Objectives

* Assess the efficacy of VTX002 when administered for 13 weeks on endoscopic changes, symptomatic response and remission, histology, and mucosal healing

* Assess the safety and tolerability of VTX002

* Assess the pharmacokinetics (PK) of VTX002

Long-Term and Open-Label Extension Objectives

* Assess the efficacy of VTX002 through the LTE and OLE Treatment Periods on endoscopic changes, symptomatic response and remission, histology, and mucosal healing

* Assess the safety of VTX002 through the LTE and OLE Treatment Periods

Primary Outcome Measures
NameTimeMethod
Clinical Remission at 13 WeeksDay 1 of Induction treatment period to Week 13

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.

Secondary Outcome Measures
NameTimeMethod
Endoscopic Improvement at Week 13Day 1 of Induction Treatment Period to Week 13

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).

Symptomatic Remission at Week 13Day 1 of Induction Treatment Period to Week 13

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.

Histologic Remission at Week 13Day 1 of Induction Treatment Period to Week 13

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.

Endoscopic Improvement-Histologic Remission at Week 13Day 1 of Induction Treatment Period to Week 13

The percentage of participants with endoscopic improvement-histologic remission at Week 13. This outcome measure was assessed by endoscopic histologic scores and defined as ES ≤ 1 (excluding friability) and a Geboes Index score \< 2.0. The ES ranged from 0 to 3 (where 0 = normal/inactive disease and 3 = severe disease). 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.
