BACKGROUND: Starting biologic treatment early in the course of inflammatory bowel disease (IBD) may associate with higher efficacy, especially in Crohn's disease (CD).
METHODS: A systematic review and individual-patient-data meta-analysis of all placebo-controlled trials of biologics approved for IBD at study inception (Oct 2015), using Vivli data-sharing platform. The primary outcome was the proportional biologic/placebo treatment effect on induction-of-remission in patients with short-duration (≤18months) versus long-duration disease (>18months) analyzed separately for CD and ulcerative colitis (UC). We used meta-regression to examine the impact of patients' characteristics on the primary outcome. Study PROSPERO registration: CRD42018041961.
RESULTS: We included 25 trials, testing infliximab, adalimumab, certolizumab, golimumab, natalizumab or vedolizumab (6,168 CD, 3,227 UC patients). In CD, induction-of-remission rates were higher in pooled placebo and active arms' patients with short-disease duration≤18 months (41.4%, 244/589) compared with disease-duration>18months (29.8%, 852/2857, meta-analytically estimated OR=1.33, 95%CI:1.09-1.64). The primary outcome, proportional biologic/placebo treatment effect on induction-of-remission, was not different in short-duration disease ≤18 months (n= 589, OR 1.47, 95%CI:1.01-2.15) compared with longer disease-duration (n=2857, OR 1.43, 95%CI:1.19-1.72). In UC trials, both the proportional biologic/placebo remission-induction effect and the pooled biologic-placebo effect were stable regardless of disease duration. Primary outcome results remained unchanged when tested using alternative temporal cut-offs and when modelled for individual-patients' co-variates, including prior anti-TNFs exposure.
CONCLUSION: There are higher rates of induction-of-remission with biologics and with placebo in early CD, resulting in a treatment-to-placebo effect ratio which is similar across disease durations. No such relationships between disease-duration and outcomes is found in UC.
BACKGROUND: There is a growing armamentarium for the treatment of moderate-to-severe ulcerative colitis. We aimed to compare the relative efficacy and safety of biologics and small molecule drugs for the treatment of patients with moderate-to-severe ulcerative colitis.
METHODS: In this systematic review and network meta-analysis, we searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials without language restrictions for articles published between Jan 1, 1990, and July 1, 2021. Major congresses' databases from Jan 1, 2018, to July 3, 2021, were reviewed manually. Phase 3, placebo-controlled or head-to-head randomised controlled trials (RCTs) assessing the efficacy and safety of biologics or small molecule drugs as induction or maintenance therapies for patients with moderate-to-severe ulcerative colitis were included. Phase 2 RCTs were excluded because of their small sample sizes and inclusion of doses not further explored in phase 3 RCTs. Summary data from intention-to-treat analyses were extracted from included reports by JSL and PAO. The primary outcome was the induction of clinical remission. A network meta-analysis was done under the frequentist framework, obtaining pairwise odds ratios (ORs) and 95% CIs. The surface under the cumulative ranking (SUCRA) was used to rank the included agents for each outcome. Higher SUCRA scores correlate with better efficacy, whereas lower SUCRA scores correlate with better safety. Maintenance data on efficacy for treat-straight-through and randomised responder trials are also presented. This study is registered with PROSPERO, CRD42021225329.
FINDINGS: Our search yielded 5904 results, from which 29 studies (four being head-to-head RCTs) fulfilled our inclusion criteria and were included. Of these, 23 studies assessed induction therapy with either a biologic or small molecule drug, comprising 10 061 patients with ulcerative colitis. A risk of bias assessment showed a low risk of bias for most of the included studies. Upadacitinib was significantly superior to all other interventions for the induction of clinical remission (infliximab [OR 2·70, 95% CI 1·18-6·20], adalimumab [4·64, 2·47-8·71], golimumab [3·00, 1·32-6·82], vedolizumab [3·56, 1·84-6·91], ustekinumab [2·92, 1·31-6·51], etrolizumab [4·91, 2·59-9·31], tofacitinib [2·84, 1·28-6·31], filgotinib 100 mg [6·15, 2·98-12·72], filgotinib 200 mg [4·49, 2·18-9·24], and ozanimod (2·70, 1·18-6·20), and ranked highest for the induction of clinical remission (SUCRA 0·996). No differences between active interventions were observed when assessing adverse events and serious adverse events. Vedolizumab ranked lowest for both adverse events (SUCRA 0·184) and serious adverse events (0·139), whereas upadacitinib ranked highest for adverse events (0·843) and ozanimod ranked highest for serious adverse events (0·831).
INTERPRETATION: Upadacitinib was the best performing agent for the induction of clinical remission (the primary outcome) but the worst performing agent in terms of adverse events in patients with moderate-to-severe ulcerative colitis. Vedolizumab was the best performing agent for safety outcomes. With the paucity of direct comparisons in the published literature, our results might help clinicians to position drugs in treatment algorithms.
FUNDING: None.
INTRODUCTION: Ustekinumab, an interleukin-12 and interleukin-23 antagonist, is licensed for the treatment of Crohn's disease (CD) and ulcerative colitis (UC) after the phase III trial programs demonstrated efficacy over placebo. However, these findings may not be directly transferable to the real-world due to the stringent inclusion criteria of clinical trials.
METHODS: We conducted a systematic review and meta-analysis of the safety and effectiveness of ustekinumab in inflammatory bowel disease (IBD). A systematic literature search was conducted via Medline and Embase from inception to April 21, 2020. Observational studies assessing ustekinumab's safety and effectiveness by reporting response, remission and/or adverse events (AE) in either CD or UC were included. Two reviewers independently assessed risk of bias and extracted study data. Random-effects meta-analysis was performed to pool rates of clinical response, remission, and safety data.
RESULTS: Following deduplication, 2147 records were identified of which 41 studies (38 CD, 3 UC) comprising 4400 patients were included for quantitative analysis. Pooled clinical remission rates for CD were 34% (95% CI, 26%-42%) following induction and 31% (95% CI, 25%-38%) at one year. For UC, post-induction clinical remission rates were 39% (95% CI, 23%-56%). Serious AEs were reported in 5.6% of patients. Pregnancy outcomes were similar to the general population. One-third of patients with active baseline perianal disease responded or had fistula healing with ustekinumab.
CONCLUSIONS: In the most comprehensive systematic review and meta-analysis to date, and the first to include UC, ustekinumab was shown to be effective and safe in the real-world treatment of IBD.
Background: Psoriasis and inflammatory bowel diseases share common immunological pathomechanisms and therefore similar treatment options.Objective: To assess already existing therapies and their efficacy versus adverse effects and paradoxical reactions in patients presenting with either disease or both.Data sources: A systematic search of the PubMed and Science.gov databases was performed for the period 2018-2020. Only articles in English were selected. Search terms included a combination of keywords: adalimumab, infliximab, etanercept, golimumab, certolizumab, ustekinumab, guselkumab, vedolizumab, secukinumab, ixekizumab, brodalumab, acitretin, cyclosporine, methotrexate, apremilast, mycophenolate mofetil, sulfasalazine, hydroxyurea, azathioprine, 6-thioguanine, tacrolimus, leflunomide and fumaric acid esters in combination with each of the following: paradoxical, psoriasis, psoriatic arthritis, inflammatory bowel disease, Chron's disease, ulcerative colitis. Other potentially relevant articles were identified by manually checking the references of the included literature.Study selection: recent reviews and meta-analyses, pooled analyses, cohort studies, observational studies, care reports were all included.Conclusions: Psoriasis and IBD can be treated concurrently as they share common inflammatory pathways. TNF-α inhibitors and IL-12/23 have been successful in treating both psoriasis and IBD. IL-17 inhibitors are recognized treatments for psoriasis but have the potential to exacerbate IBD. Newer molecules require further clinical trials and real-life studies in order to confirm their efficacy and safety.
GOALS AND BACKGROUND: Ustekinumab (UST) is a monoclonal antibody inhibitor of IL-12/IL-23 approved for the treatment of Crohn's disease (CD) and ulcerative colitis (UC). We conducted a meta-analysis to compare rates of adverse events (AEs) in randomized controlled trials (RCTs) of UST for all indications.
STUDY: A systematic search was performed of MEDLINE, Embase, and PubMed databases through November 2019. Study inclusion included RCTs comparing UST to placebo or other biologics in patients aged 18 years or older with a diagnosis of an autoimmune condition.
RESULTS: Thirty RCTs with 16,068 patients were included in our analysis. Nine thousand six hundred and twenty-six subjects were included in the UST vs placebo analysis. There was no significant difference in serious or mild/moderate AEs between UST and placebo with an OR of 0.83 (95% CI 0.66, 1.05) and 1.08 (95% CI 0.99, 1.18), respectively, over a median follow-up time of 16 weeks. In a sub-analysis of CD and UC trials, no difference in serious or mild/moderate AEs in UST versus placebo was seen.
CONCLUSIONS: UST was not associated with an increase in short-term risk of AEs.
Background: Crohn disease (CD) is a chronic inflammatory disease that affects quality of life. There are several drugs available for the treatment of CD, but their relative efficacy is unknown due to a lack of high-quality head-to-head randomized controlled trials. Aim: To perform a mixed comparison of the efficacy and safety of biosimilars, biologics and JAK1 inhibitors for CD. Methods: We searched PubMed, Web of Science, embase and the Cochrane Library for randomized controlled trials (RCTs) up to Dec. 28, 2020. Only RCTs that compared the efficacy or safety of biosimilars, biologics and JAK1 inhibitors with placebo or another active agent for CD were included in the comparative analysis. Efficacy outcomes were the induction of remission, maintenance of remission and steroid-free remission, and safety outcomes were serious adverse events (AEs) and infections. The Bayesian method was utilized to compare the treatments. The registration number is CRD42020187807. Results: Twenty-eight studies and 29 RCTs were identified in our systematic review. The network meta-analysis demonstrated that infliximab and adalimumab were superior to certolizumab pegol (OR 2.44, 95% CI 1.35–4.97; OR 2.96, 95% CI 1.57–5.40, respectively) and tofacitinib (OR 2.55, 95% CI 1.27–5.97; OR 3.10, 95% CI 1.47–6.52, respectively) and revealed the superiority of CT-P13 compared with placebo (OR 2.90, 95% CI 1.31–7.59) for the induction of remission. Infliximab (OR 7.49, 95% CI 1.85–34.77), adalimumab (OR 10.76, 95% CI 2.61–52.35), certolizumab pegol (OR 4.41, 95% CI 1.10–21.08), vedolizumab (OR 4.99, 95% CI 1.19–25.54) and CT-P13 (OR 10.93, 95% CI 2.10–64.37) were superior to filgotinib for the maintenance of remission. Moreover, infliximab (OR 3.80, 95% CI 1.49–10.23), adalimumab (OR 4.86, 95% CI 1.43–16.95), vedolizumab (OR 2.48, 95% CI 1.21–6.52) and CT-P13 (OR 5.15, 95% CI 1.05–27.58) were superior to placebo for steroid-free remission. Among all treatments, adalimumab ranked highest for the induction of remission, and CT-P13 ranked highest for the maintenance of remission and steroid-free remission. Conclusion: CT-P13 was more efficacious than numerous biological agents and JAK1 inhibitors and should be recommended for the treatment of CD. Further head-to-head RCTs are warranted to compare these drugs.
Objectives: Because only one head-to-head randomized trial of biologics for moderate-to-severe ulcerative colitis (UC) has been performed, indirect treatment comparisons remain important. This systematic review and network meta-analysis examined efficacy and safety of biologics and tofacitinib for moderate-to-severe UC, using values for vedolizumab as a reference. Methods: Relevant studies (N=19) of vedolizumab, adalimumab, infliximab, golimumab, ustekinumab, and tofacitinib were identified. Study design differences were addressed by assessing efficacy outcomes conditional on response at maintenance initiation. Primary analysis used fixed-effect models to estimate odds ratios for efficacy and safety endpoints. Results: Compared with vedolizumab 300 mg, adalimumab 160/80 mg was associated with less clinical remission (odds ratio, 0.69 [95% credible interval, 0.54-0.88]), and infliximab 5 mg/kg was associated with more clinical remission (1.67 [1.16-2.42]) and response (1.63 [1.15-2.30]). Adalimumab 40 mg, golimumab 50 mg, and ustekinumab 90 mg Q12W had significantly lower clinical remission rates during maintenance (0.62 [0.45-0.86], 0.55 [0.32-0.95], and 0.59 [0.35-0.99]) versus vedolizumab 300 mg Q8W. Response results were similar. Tofacitinib 10 mg had the highest maintenance treatment efficacy estimates and highest infection risk. Conclusion: Network meta-analysis and novel integrated benefit-risk analysis suggest a potentially favorable efficacy-safety balance for vedolizumab compared with adalimumab and other advanced UC therapies.
Ustekinumab (STELARA®), a human monoclonal antibody directed against IL-12 and IL-23, is FDA-approved to treat psoriasis, psoriatic arthritis, Crohn's disease, and ulcerative colitis. Increasing recognition of paradoxical skin reactions induced by older biologic therapies used for inflammatory bowel diseases (IBD), such as adalimumab and infliximab, has led to the investigation of ustekinumab for the treatment of the cutaneous and gastrointestinal manifestations of IBD. In addition, ustekinumab may show efficacy in treating paradoxical cutaneous reactions to tumor necrosis factor-alpha (TNF-α) inhibitors. A search of the Medline/PubMed database, with additional citations obtained from the references section of relevant articles, yielded 22 articles that were included in this review. Ustekinumab is a safe and effective option for treating the cutaneous manifestations of IBD, such as metastatic Crohn's disease and pyoderma gangrenosum. It is also an effective treatment for TNF-α inhibitor-induced paradoxical skin reactions such as psoriasis that do not remit spontaneously or with conventional treatment. Additional studies should focus on the optimal dosing of ustekinumab for dermatologic conditions beyond psoriasis. This article is protected by copyright. All rights reserved.
BACKGROUND & AIMS: There is debate over whether patients with inflammatory bowel diseases (IBD) treated with biologics that are not tumor necrosis factor antagonists (such as vedolizumab or ustekinumab) should receive concomitant treatment with immunomodulators. We conducted a meta-analysis to compare the efficacy and safety of concomitant immunomodulator therapy vs vedolizumab or ustekinumab monotherapy.
METHODS: In a systematic search of publications, through July 31, 2019, we identified 33 studies (6 randomized controlled trials and 27 cohort studies) of patients with IBD treated with vedolizumab or ustekinumab. The primary outcome was clinical benefit, including clinical remission, clinical response, or physician global assessment in patients who did vs did not receive combination therapy with an immunomodulator. Secondary outcomes were endoscopic improvement and safety. We performed random-effects meta-analysis and estimated odds ratio (OR) and 95% CIs.
RESULTS: Overall, combination therapy was not associated with better clinical outcomes in patients receiving vedolizumab (16 studies: OR, 0.84; 95% CI, 0.68-1.05; I2=13.9%; Q test P=.17) or ustekinumab (15 studies: OR, 1.1; 95% CI, 0.87-1.38; I2=11%; Q test P=.28). Results were consistent in subgroup analyses, with no difference in clinical remission or response in induction vs maintenance studies or in patients with Crohn's disease vs ulcerative colitis in studies of vedolizumab. Combination therapy was not associated with better endoscopic outcomes in patients receiving vedolizumab (3 studies: OR, 1.13; 95% CI, 0.48-2.68; I2=0; Q test P=.96) or ustekinumab (2 studies: OR, 0.58; 95% CI, 0.21-1.16; I2=47%; Q test P=.17). Combination therapy was not associated with an increase in adverse events during vedolizumab therapy (4 studies: OR, 1.17; 95% CI, 0.75-1.84; I2=0; Q test P=.110).
CONCLUSIONS: In a meta-analysis of data from studies of patients with IBD, we found that combining vedolizumab or ustekinumab with an immunomodulator is no more effective than monotherapy in induction or maintenance of remission.
BACKGROUND AND AIMS: Extraintestinal manifestations (EIMs) are frequent in patients with inflammatory bowel diseases (IBD) and a challenging condition to manage. Tumor necrosis factor alpha antagonists (anti-TNFα) are recognized as the primary therapeutic option. We aimed to summarize evidence on the efficacy of ustekinumab for the treatment of EIMs.
METHODS: We searched in PubMed, Cochrane Library, and Web of Science up to October 2020 all interventional and non-interventional studies published in English assessing ustekinumab efficacy for the treatment of EIMs.
RESULTS: Nine studies (8 retrospective and 1 prospective) were included, enrolling a total of 254 patients with IBD and EIM. Ustekinumab showed its effectiveness for arthralgia and psoriatic arthritis in 152 patients through 3 high quality studies. Conversely, no efficacy was found in axial spondyloarthritis. Psoriasis, pyoderma gangrenosum and erythema nodosum were assessed in 7 studies including 65 patients and showed high response rate to ustekinumab treatment. Promising results for aphthous stomatitis and uveitis were reported, but data were limited to 20 patients from 2 studies.
CONCLUSIONS: Ustekinumab showed to be an effective option for the treatment of EIMs, especially for dermatological and rheumatological manifestations. However, more data are needed to confirm the role of ustekinumab in this setting.
Starting biologic treatment early in the course of inflammatory bowel disease (IBD) may associate with higher efficacy, especially in Crohn's disease (CD).
METHODS:
A systematic review and individual-patient-data meta-analysis of all placebo-controlled trials of biologics approved for IBD at study inception (Oct 2015), using Vivli data-sharing platform. The primary outcome was the proportional biologic/placebo treatment effect on induction-of-remission in patients with short-duration (≤18months) versus long-duration disease (>18months) analyzed separately for CD and ulcerative colitis (UC). We used meta-regression to examine the impact of patients' characteristics on the primary outcome. Study PROSPERO registration: CRD42018041961.
RESULTS:
We included 25 trials, testing infliximab, adalimumab, certolizumab, golimumab, natalizumab or vedolizumab (6,168 CD, 3,227 UC patients). In CD, induction-of-remission rates were higher in pooled placebo and active arms' patients with short-disease duration≤18 months (41.4%, 244/589) compared with disease-duration>18months (29.8%, 852/2857, meta-analytically estimated OR=1.33, 95%CI:1.09-1.64). The primary outcome, proportional biologic/placebo treatment effect on induction-of-remission, was not different in short-duration disease ≤18 months (n= 589, OR 1.47, 95%CI:1.01-2.15) compared with longer disease-duration (n=2857, OR 1.43, 95%CI:1.19-1.72). In UC trials, both the proportional biologic/placebo remission-induction effect and the pooled biologic-placebo effect were stable regardless of disease duration. Primary outcome results remained unchanged when tested using alternative temporal cut-offs and when modelled for individual-patients' co-variates, including prior anti-TNFs exposure.
CONCLUSION:
There are higher rates of induction-of-remission with biologics and with placebo in early CD, resulting in a treatment-to-placebo effect ratio which is similar across disease durations. No such relationships between disease-duration and outcomes is found in UC.
