Clinical Trial Summary

This is a multicenter, randomized, double-blind placebo-controlled, parallel group study to evaluate the efficacy and safety of VTX958 in participants with moderately to severely active Crohn's Disease.

Description:

This is a multicenter, randomized, double-blind placebo-controlled, parallel group study to evaluate the efficacy and safety of VTX958 in participants with moderately to severely active Crohn's Disease. Approximately 132 eligible patients will be randomized, and randomization will be stratified by prior use of biologics for the treatment of CD (yes/no). The study consists of a 30-day Screening Period, a 12-week double-blind Induction Treatment Period, a 40-week double-blind Maintenance Treatment Period, an Open-Label Extension (OLE) of up to 144 weeks, and a 30-day safety Follow-Up Period. The maximum duration of treatment will be 36 months, including the Induction, Maintenance, and OLE Periods. For all participants, a Follow-Up visit will be performed at 30 days after the last dose of study drug. Objectives Primary Objectives * Evaluate the efficacy of VTX958 in achieving reduction in Crohn's Disease Activity Index (CDAI) score and endoscopic response at the end of the Induction Period Secondary Objectives - Evaluate the efficacy of VTX958 in inducing clinical and symptomatic response and remission at the end of the Induction Period - Evaluate the efficacy of VTX958 in inducing endoscopic response and clinical remission at the end of the Induction Period

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in mean Crohn's disease Activity Index (CDAI) score from baseline to week 12	Change in Mean CDAI (Crohn's disease Activity Index). CDAI is a weighted index comprising eight Crohn's Disease (CD)-related clinical and laboratory variables, to assess CD disease activity. Three of the variables, stool frequency, abdominal pain, and general well-being, are patient-reported measures recorded daily. The total CDAI score is calculated using the sum of each variable times the multiplier. The total score range of the CDAI is from 0 to 600.	During screening to week 12
Primary	The proportion of participants achieving endoscopic response at Week 12	SES-CD is an endoscopic grading system is used to assess CD disease activity. The SES-CD assesses 4 endoscopic variables: the size of ulcers, ulcerated surface, affected surface, and presence of narrowing. Each variable score ranging from 0 to 3. The total SES-CD score is calculated using the sum of all parameter scores in 5 segments: terminal ileum, right colon, transverse colon, left colon, and rectum.	During screening to week 12
Secondary	Change from baseline in mean simple endoscopic score in Crohn's disease SES-CD at Week 12	Change from baseline in mean simple endoscopic score in Crohn's disease SED-CD at 12 weeks. The SES-CD is an endoscopic grading system is used to assess CD disease activity. The SES-CD assesses 4 endoscopic variables: the size of ulcers, ulcerated surface, affected surface, and presence of narrowing. Each variable score ranging from 0 to 3. The total SES-CD score is calculated using the sum of all parameter scores in 5 segments: terminal ileum, right colon, transverse colon, left colon, and rectum.	During screening to week 12
Secondary	Proportion of participants achieving clinical remission at Week 12	Clinical remission is defined as a CDAI score < 150. CDAI is a weighted index comprising eight Crohn's Disease (CD)-related clinical and laboratory variables, to assess CD disease activity. Three of the variables, stool frequency, abdominal pain, and general well-being, are patient-reported measures recorded daily. The total CDAI score is calculated using the sum of each variable times the multiplier. The total score range of the CDAI is from 0 to 600.	During screening to week 12
Secondary	Proportion of participants achieving patient-reported outcome 2 (PRO2) remission at Week 12	The proportion of participants achieving PRO2 remission at week 12. PRO2 remission is defined is an unweighted CDAI component of daily AP score = 1 and unweighted CDAI component of daily average stool frequency (SF) score = 3	During screening to week 12
Secondary	Proportion of participants achieving clinical response at Week 12	Proportion of participants achieving clinical response at Week 12. A clinical response is defined as = 100 points reduction from baseline in CDAI score or CDAI score < 150. CDAI is a weighted index comprising eight Crohn's Disease (CD)-related clinical and laboratory variables, to assess CD disease activity. Three of the variables, stool frequency, abdominal pain, and general well-being, are patient-reported measures recorded daily. The total CDAI score is calculated using the sum of each variable times the multiplier. The total score range of the CDAI is from 0 to 600.	During screening to week 12
Secondary	Proportion of participants achieving both endoscopic response (outcome- measure # 2) and clinical remission (outcome measure # 4) at Week 12	Proportion of participants achieving both endoscopic response (as described in outcome measure 2) and clinical remission (as described in outcome measure 4) at Week 12.	During screening to week 12
