Introduction

The Phase 2 GALAXI 1 study evaluated the efficacy and safety of guselkumab (GUS), a human selective IL-23p19 subunit antagonist, in patients (pts) with moderate to severe Crohn’s disease (CD). Pts were randomized to GUS, ustekinumab (UST), or placebo (PBO) through Week (Wk) 48 without rerandomization after IV induction. Previously, we reported that pts who were in clinical response after IV induction had higher rates of clinical and endoscopic outcomes at Wk48 than the overall study population.¹ In this post hoc analysis, we report outcomes for pts who did not achieve Wk12 clinical response based on CD activity index (CDAI) after IV induction.

Aims & Methods

Pts were randomized 1:1:1:1:1 to induction with GUS 200, 600, or 1200mg IV, UST ~6mg/kg IV, or PBO IV. At Wk12 (Wk8 for UST), pts were transitioned to maintenance dosing: GUS 200mg IV→100mg subcutaneous (SC) q8w, GUS 600mg IV→200mg SC q4w, GUS 1200mg IV→200mg SC q4w, UST ~6mg/kg IV→90mg SC q8w, PBO nonresponders→UST ~6mg/kg IV→90mg SC q8w, and PBO responders→PBO SC q4w. Clinical response (all time points) was defined as ≥100-point reduction from baseline in CDAI or CDAI <150. Other endpoints included clinical remission (CDAI <150), pt-reported outcome (PRO)-2 remission (unweighted CDAI components of average daily abdominal pain score ≤1 and average daily stool frequency ≤3, and no worsening from baseline), and endoscopic response (≥50% improvement from baseline in simple endoscopic score [SES]-CD or SES-CD ≤2). The study was not powered to evaluate between-group efficacy differences at Wk48; UST was used for reference.

Results

Conclusion

Pts not responding to IV induction with GUS may benefit from continued SC dosing. Among pts who did not achieve clinical response at Wk12, continued treatment with GUS SC resulted in nearly half achieving clinical response at Wk24. At Wk48, a majority achieved clinical response, >40% achieved either clinical remission or PRO-2 remission, and >30% achieved endoscopic response.

Introduction

Quality patient information is the cornerstone of personalised cancer care, empowering treatment decisions and improving patient outcomes. As a team of colorectal nurse specialists in a large hospital trust in the Northeast of England we undertook a quality improvement project to enhance information provision for patients diagnosed with bowel cancer. This initiative was prompted by recognition of both the critical importance of accurate information for cancer patients and the need to adapt service delivery during the COVID-19 pandemic

Results & Findings

The quality improvement project began with a comprehensive survey designed to evaluate patients' perceptions of current information provision and gather suggestions for enhancement. Twenty patients, deliberately selected to represent diverse demographic profiles, participated in the survey. A striking finding was that 80% of respondents sought additional information about their condition from internet sources, particularly from trusted websites like NHS Choices, Macmillan, and Cancer Research UK. The same percentage expressed interest in more visual content such as photos of staff, and most indicated a preference for accessing digital information alongside traditional printed materials.
Following the survey, two focus group workshops were conducted in collaboration with the NHS organisation dedicated to personalised care approaches. The focus groups examined patient experiences across the entire care pathway, from initial referral through treatment and follow-up, guided by principles of realistic medicine and shared decision-making.
We presented several innovative proposals for information delivery: an interactive diagram of the colorectal cancer journey accessible via the Trust's website; patient contact cards containing team details, phone numbers, website links, and QR codes; a webpage featuring QR codes linking to specific information resources; a video depicting the patient journey from referral through investigations; and plans to refresh the existing service webpage. These proposals aligned with the survey finding that most patients used online resources for information.

Summary & Discussion

This quality improvement initiative has provided us with valuable insights and confidence to advance information provision strategy in ways that genuinely reflect patient needs and experiences. The findings support a multimedia approach combining digital and traditional resources, with particular emphasis on accessible online information that patients can engage with at their own pace. As a team we created a patient information pathway that mirrors the actual patient journey and authentically reflects diverse patient experiences.

Conclusion

The project demonstrates the value of collaborative approaches to service improvement that meaningfully involve patients as partners. By putting patients at the heart of t project, the colorectal nursing team was positioned to develop information resources that truly meet patient needs during a challenging time in their lives. This patient-centred approach to information provision exemplifies the team's commitment to not only meet but exceed patient expectations in their privileged role as cancer care providers.

Introduction

Duvakitug, a human IgG1 monoclonal antibody, inhibits TL1A binding to death receptor 3 (DR3), which drives inflammation in Crohn’s disease (CD). The RELIEVE-UCCD trial (NCT05499130), a 14-week induction study, evaluated duvakitug in ulcerative colitis and CD. This was the first placebo-controlled study of an anti-TL1A in moderately to severely active CD. This subgroup analysis was performed to understand the impact of duvakitug in patients with moderate and severe endoscopic inflammation by assessing Week 14 outcomes in subgroups based on endoscopic disease severity at baseline.

Aims & Methods

Patients with CD (N=138) were randomized (1:1:1) to receive a subcutaneous (SC) loading dose (LD) of duvakitug 2250 mg followed by SC duvakitug 900 mg or duvakitug 450 mg every 2 weeks (q2w), or matching placebo LD followed by placebo q2w. Patients were required to have a simple endoscopic score for Crohn’s disease (SES-CD) ≥6 (≥4 for isolated ileal disease) for study eligibility. In this analysis, endoscopic and patient-reported clinical outcomes were assessed by baseline SES-CD scores of ≤15 (moderate) and >15 (severe).¹ Endpoints included response and remission based on endoscopic assessment (SES-CD) and clinical assessment [2-item Patient Reported Outcome assessment tool (PRO2)] at Week 14. Outcomes were analyzed using descriptive summary statistics.

Results

Among patients with severe endoscopic activity (SES-CD >15) at baseline, endoscopic response was achieved by 36% in the duvakitug 900 mg arm, and 18% in the duvakitug 450 mg arm compared to 8% in the placebo arm. In patients with moderate endoscopic activity (SES-CD ≤15) at baseline, endoscopic response was achieved by 51% in the duvakitug 900 mg arm, and 29% in the duvakitug 450 mg arm compared to 15% in the placebo arm (Table). Greater proportion of patients achieved endoscopic remission, clinical response and remission with both doses of duvakitug compared to placebo in the moderate and severe endoscopic subgroups (Table). The overall adverse event profile was similar across treatment arms by disease severity subgroups.

Conclusion

In CD patients, duvakitug demonstrated efficacy in endoscopic and patient-reported clinical outcomes in both moderate and severe endoscopic activity subgroups in this Phase 2b study. Duvakitug was well tolerated across both subgroups. These findings support further development of duvakitug as a potential treatment option for moderately to severely active CD.
