Introduction

Patient-reported outcome measures (PROMs) are recommended for assessing patient-centered outcomes and have been suggested as a tool for quality improvement (QA), which is crucial for IBD related outcomes and as clinical trials' endpoints. Real world use of IBD PROMS as a monitoring tool that enables quick access to caregivers, is still rare. Maccabi Healthcare Services (MHS), a state-mandated healthcare provider with over 2.6 million members, emphasizes patients' cooperation in improving their health and quality of life.

Aims & Methods

Aims: 1. To implement an IBD PROMS platform according to an operational process, which triggers a response from an IBD nurse and a multidisciplinary team, for routine HMO clinical use.
2. To compare the characteristics of responders and non-responders and study immediate actions.
Methods: We have used pre-existing research on the IBD PROMS platform(1) to implement validated questionnaires (IBD control PROMIS-10 measures and general health and nutritional items). Questionnaires translated into four languages were sent every 3 months to IBD registry members (defined by EPI-IRN criteria) via text messages. The calculated results and scores are directed to the electronic medical record (EMR) and are accessible to all caregivers. Digital alerts are sent to an IBD nurse in cases of "red flags" or low scores. A steering committee designed an actionable plan defining specific nurse responses for each red flag, and whether to consult with the treating physician, dieticians or social worker. A pilot study with patients from 6 gastroenterologists included 2 rounds of PROMS. Descriptive statistics were used to compare the responders to at least one questionnaire to non-responders for demographic and clinical characteristics, as well as for immediate reactions. An automated, language-specific, personalized messaging system according to patient response was accessible to the responders, with relevant information and general recommendations.

Results

Overall participation rate of the pilot study was 137/777(17.6%). Thirty one (23%) patients had red flags and 52(38%) had sub-threshold IBD-control scores. Opening rate of the personalized messaging system was 41%. Comparison between responders and non-responders is shown in Table 1. Responders tended to be significantly older and with a higher BMI. Medical treatment including biologics was not significantly different between responders and non-responders. More disease related laboratory tests were performed among responders after their initial response.

Conclusion

IBD PROMS has been successfully assimilated and operated at MHS EMR by a multidisciplinary team, using a supporting personalized automated platform. Significantly higher rate of disease monitoring actions such as calprotectin tests was detected for responders. Responders did not necessarily have a more active or severe disease. The response rate should be increased via robust education and training.

Introduction

Precision medicine aims to expand upon the summary average treatment effects reported in clinical trials by providing more refined, individualised estimates of treatment effects. The phase IIb TUSCANY-2 study (NCT04090411), which examined the efficacy and safety of afimkibart (RO7790121/RG6631; previously PF-06480605/RVT-3101), an anti-TL1A antibody, in patients (pts) with moderate to severe ulcerative colitis (UC), previously reported clinically meaningful treatment effects at UEGW 2024.¹ Here, we report post hoc analyses of the relationship between baseline clinical characteristics and Week 14 efficacy in pts enrolled in TUSCANY-2.

Aims & Methods

Pts were randomised to receive subcutaneous afimkibart 50mg, 150mg, 450mg or matched placebo (PBO) monthly during induction. In this post hoc analysis, all afimkibart doses were pooled, and the endpoint of interest was clinical remission by modified Mayo score (mMS; defined as stool frequency subscore=0 or 1; rectal bleeding subscore=0; and endoscopic subscore [ES]=0 or 1) at Week 14. Our investigation of more patient-specific treatment effects was guided by the Predictive Approaches to Treatment effect Heterogeneity (PATH) statement.² We developed a regularised logistic regression model to predict the probability of Week 14 remission and to help examine heterogeneity of treatment effects based on the following baseline characteristics: mMS, C-reactive protein (CRP), serum albumin, Robart’s Histopathology Index (RHI), number of failed advanced therapy classes, corticosteroid use, disease extent, disease duration, age and sex. Baseline faecal calprotectin (FCP) was investigated separately due to the extent of missing data.

Results

The proportion of pts achieving clinical remission by mMS at Week 14 in the afimkibart pooled dose arm was 32.5% (65/200; 90% confidence interval [CI]: 27.3 to 38.1) compared with 13.3% (6/45; 90% CI: 7.1 to 23.8) of pts in the PBO arm (treatment delta: 19.2%; 90% CI: 7.6 to 27.9). Based on calibrated predictions from the multivariate model, all of the individual TUSCANY-2 pts (both treated with PBO and afimkibart) had anywhere between a 2–76% probability of Week 14 remission at baseline. The clinical characteristics included in the model explained ~10% of the variability in the observed outcomes. There was no evidence that the clinical characteristics were associated with heterogeneous treatment effects on the relative scale (odds ratios appeared to be constant; p-value >0.5). On the clinically meaningful absolute scale, the treatment delta in the top 50% of pts with a higher baseline probability of remission (27–76%) was 28.5% (90% CI: 8 to 42; 45.2% in afimkibart pooled dose arm vs 16.7%, in PBO arm), compared with a treatment delta of 7.6% (90% CI: –7 to 18; 18.8% in afimkibart pooled dose arm vs 11.1%, in PBO arm) in pts with a lower baseline probability of remission (2–27%). Lower baseline CRP, lower RHI and higher serum albumin contributed to a greater probability of remission and absolute benefit from treatment with afimkibart.

Conclusion

Pts with inflammatory bowel disease (IBD) have diverse baseline characteristics that are associated with variability of treatment outcomes, yet clinicians rely on reported averages from clinical trials to make individual treatment decisions. This analysis demonstrates how precision medicine approaches, that account for diverse characteristics, may improve interpretation of positive IBD clinical trial results. Integrating genetic and novel biomarkers alongside clinical features could help to better predict individual outcomes for pts with IBD.

Introduction

Most inflammatory bowel disease (IBD) randomised controlled trials (RCTs) only permit tapering of corticosteroids after initiating the maintenance period, either as adaptive or forced tapering, resulting in different corticosteroid exposure among participants.¹ These practices result in inappropriately, prolonged, and excessive exposure to corticosteroids that is not consistent with optimal clinical care and may inflate placebo response rates.^2-7

Aims & Methods

We aimed to provide comprehensive standardised recommendations on key aspects of corticosteroid use in RCTs for adults with moderately-to-severely active IBD, through a multi-phase, international expert consensus. The consensus was informed by a systematic review of MEDLINE, EMBASE, and the Cochrane CENTRAL Register of Controlled Trials which determined the corticosteroid management rules used in placebo-controlled trials of advanced therapies in IBD. Expert consensus recommendations for all aspects of corticosteroid management in RCTs were then developed using a modified Delphi process with two rounds of survey questions and a ratification meeting. For the surveys, corticosteroid management practices were divided into several domains describing the key stages of an IBD RCT and were directly reflected in clinical trial protocols: corticosteroid management during screening, induction, and maintenance; and corticosteroid-related endpoints.

Results

The international Delphi panel consisted of 45 IBD RCT experts. The recommendations propose management of corticosteroid intake during screening, induction, and maintenance phases of pharmacologic RCTs in IBD, and define corticosteroid-related endpoints. The need for minimising corticosteroid exposure through expedited tapering and shorter fixed-dosing periods that more closely reflect routine clinical care was emphasised, and recommendations for standardised definitions of corticosteroid-free remission were provided (Table). The panellists recommended a 2-week stable dosing period before screening, and favoured beginning dosage tapering at ≤2 weeks of induction. Panellists supported a unified tapering protocol of 5 mg prednisone equivalents/week, and voted that enteric- and colonic-release corticosteroids do not require tapering. A point of consensus was that both the beginning of tapering and its rate should be mandated by the trial protocol, rather than the investigators’ discretion. Consensus was not reached on the duration of corticosteroid withdrawal prior to the final study visit for defining corticosteroid-free remission. During the ratification meeting, the panellists highlighted the need for meticulous documentation of corticosteroid use during RCTs to avoid underreporting.

Conclusion

This set of internationally guided recommendations will serve to improve optimisation of RCT design and facilitate appropriate, acceptable, and standardised corticosteroid handling practices in RCTs, as well as maximise comparability between trials and minimise steroid-related harm to trial participants.

Introduction

While three JAK inhibitors are now available in Ulcerative Colitis (UC), the hierarchy of these treatments according to their effectiveness, remains to be determined.

Aims & Methods

In the JAKARTA study, we aimed to compare the effectiveness of the three available JAK inhibitors (tofacitinib/TOFA, filgotinib/FILGO and upadacitinib/UPA) in bio-exposed patients with UC.
In this retrospective multicenter study (12 centres), we included all consecutive patients with UC ≥18 years-old, partial Mayo score > 2 who had started TOFA, FILGO or UPA after receiving ≥ 1 biologic between JAN2019 and JUN2022. Acute severe UC were excluded.
Following regimen were applied for TOFA (10mg b.i.d until W8 and 5mg or 10 mg b.i.d according to physician’s judgement), FILGO (200mg q.d) and UPA (45mg q.d until W8 and 45mg, 30 mg or 15 mg q.d according to physician’s judgement).
The primary endpoint was symptomatic remission (partial Mayo score ≤ 2) without corticosteroids (CFREM) at W16. Secondary endpoints were clinical and endoscopic remission (CFREM + endoscopic Mayo score ≤ 1), histological and endoscopic mucosal improvement (HEMI) (= clinical-endoscopic and histological remission (Nancy index ≤ 1)), drug retention (treatment discontinuation-free survival using Kaplan-Meier curve), time to colectomy, time to UC-related hospitalization and secondary loss of response among patients in CFREM at W16.
All the comparisons were performed using propensity scores adjustment (IPTW).

Results

A total of 290 patients were included: 150, 79 and 61 in TOFA, FILGO, and UPA arms, respectively. The 3 groups were comparable except for higher proportion of patients with previous exposure to > 3 biologics in UPA group (p < 0.001). TOFA 10 mg b.i.d was continued until W16 in 47.0% of patients. FILGO was maintained at 200 mg in 97.5%. UPA was diminished at 30 mg and 15 mg at W8 in 55.6% and 3.3% of patients, respectively.
After IPTW, CFREM at W16 was higher in UPA (60.1%) compared to TOFA (38.9%) or FILGO groups (36.0%) (p = 0.026 and 0.016, respectively). No predictive factor of efficacy/ failure was identified with these 3 JAK inhibitors.
We failed to show any significant difference regarding clinical-endoscopic remission (UPA:16.5%, TOFA:16.5%, FILGO:12.8%) or HEMI (UPA:11.9%, TOFA: 4.4, FILGO: 12.7%) at W16.
Among patients who reduced the dose to the recommended maintenance regimen (TOFA 5 mg b.i.d and UPA 30 or 15 mg q.d) between W8 and W16, the need for dose re-escalation to the induction dose was 33.8% (27/80) for TOFA, 14.7% (5/34) for UPA30mg and 50.0 % (1/2) for UPA 15 mg. After adjustment, drug retention was longer for UPA compared to TOFA (HR = 0.38 [0.17-0.85], p = 0.019) and FILGO groups (HR = 0.17 [0.08-0.65], p < 0.001) and shorter in FILGO than in TOFA group (HR = 1.57[1.02-2.41], p = 0.038).
No difference was demonstrated in terms of time to hospitalization or surgery between the 3 groups.
Among patients achieving CFREM at W16 (regardless of the dose), secondary loss of response (symptomatic relapse) was similar for TOFA:12.8% (N=47 patients), FILGO: 19.2% (N = 26 patients) and UPA: 10.3% (N = 29 patients) (p=ns after IPTW).

Conclusion

In this real-world evidence multicenter study, UPA was the most effective JAK inhibitor in UC at short and long-term but the large use of off-label maintenance doses in current practice needs further safety investigations.

Introduction

Subcutaneous vedolizumab has become available for the treatment of inflammatory bowel diseases in 2021 after intravenous induction. The aim of this multicentre prospective study was to evaluate treatment persistence, efficacy and tolerance after switching from intravenous (IV) to subcutaneous (SC) vedolizumab (VDZ) in stable patients.

Aims & Methods

All consecutive patients with either ulcerative colitis (UC) or Crohn’s disease (CD), in clinical remission for at least 3 months and switching from IV to SC-VDZ, were included in this multicentre cohort study. Inclusion could take place prospectively or within 3 months after switch. Clinical remission was defined by partial Mayo score ≤2 for UC or Harvey Bradshaw index ≤4 for CD; concomitant 5-amonisalycilate or immunosuppressive treatment was allowed at stable doses. Concomitant biologic or JAK-inhibitor treatments were not permitted during the study period, which lasted for 12 months after switch. SC-VDZ was started at 108 mg every other week. Primary endpoint was SC-VDZ treatment persistence at 54 weeks (W54) after switch; need for surgery, prolonged corticosteroid courses (>14 days) and loss of follow-up were considered as treatment failure. This is an analysis based on early 6-months (M6) results, reporting rates of treatment persistence, need for optimisation, switch-back to IV-VDZ and adverse events.

Results

Overall, 337 patients were analysed of 348 included, after removal of 10 patients who had an active disease and one an active infection: 246 patients (73%) had UC, 91 (27%) had CD, with a median disease duration of 9 years [interquartile range: 4-17] in UC and 13 [8-19] years in CD. Patients with UC had been on IV-VDZ for a median time of 1.4 years [0.4-3.3] prior to switch, compared to 3.1 [1.3-6.1] for CD patients, with 205 patients overall (62%) on standard IV-VDZ regimen (300mg 8-weekly).
At M6, the SC-VDZ discontinuation-free survival rate was 93.9% [95% confidence interval: 91.3 - 96.5], with no significant difference between CD and UC (p=0.6). During follow-up, 33 patients (10%) had SC-optimisation, with similar rates in both diseases. Among them, 63% has an optimised IV-VDZ regimen prior to switch. In total, 13 (4%) patients switched-back to IV-VDZ: 3 due to loss of response despite SC-VDZ optimisation, 7 for injection site reaction and 3 for various non severe adverse-events. 181 (54%) patients declared adverse events, the most frequent being injection site reactions (20%) and infections (17%). Only one serious adverse event potentially related to treatment was reported (a digestive infection that led to hospitalisation with negative testing), though it did not lead to treatment discontinuation.

Conclusion

In this multicentre prospective cohort of patients with CD or UC in clinical remission who switched from IV to SC vedolizumab, drug persistence rate at 6 months was over 90%, with good safety results. 12-month results are pending.
