ABSTRACT
BACKGROUND & AIMS: We evaluated the efficacy and safety of upadacitinib, an oral selective Janus kinase 1 inhibitor, in a randomized trial of patients with Crohn's disease (CD). METHODS: We performed a double-blind, phase 2 trial in adults with moderate to severe CD and inadequate response or intolerance to immunosuppressants or tumor necrosis factor antagonists. Patients were randomly assigned (1:1:1:1:1:1) to groups given placebo; or 3 mg, 6 mg, 12 mg, or 24 mg upadacitinib twice daily; or 24 mg upadacitinib once daily and were evaluated by ileocolonoscopy at weeks 12 or 16 of the induction period. Patients who completed week 16 were re-randomized to a 36-week period of maintenance therapy with upadacitinib. The primary endpoints were clinical remission at week 16 and endoscopic remission at week 12 or 16 using the multiple comparison procedure and modeling and the Cochran-Mantel-Haenszel test, with a 2-sided level of 10%. RESULTS: Among the 220 patients in the study, clinical remission was achieved by 13% of patients receiving 3 mg upadacitinib, 27% of patients receiving 6 mg upadacitinib (P < .1 vs placebo), 11% of patients receiving 12 mg upadacitinib, and 22% of patients receiving 24 mg upadacitinib twice daily, and by 14% of patients receiving 24 mg upadacitinib once daily, vs 11% of patients receiving placebo. Endoscopic remission was achieved by 10% (P < .1 vs placebo), 8%, 8% (P < .1 vs placebo), 22% (P < .01 vs placebo), and 14% (P < .05 vs placebo) of patients receiving upadacitinib, respectively, vs none of the patients receiving placebo. Endoscopic but not clinical remission increased with dose during the induction period. Efficacy was maintained for most endpoints through week 52. During the induction period, patients in the upadacitinib groups had higher incidences of infections and serious infections vs placebo. Patients in the twice-daily 12 mg and 24 mg upadacitinib groups had significant increases in total, high-density lipoprotein, and low-density lipoprotein cholesterol levels compared with patients in the placebo group. CONCLUSIONS: In a phase 2 trial of patients with CD, upadacitinib induced endoscopic remission in a significant proportion of patients compared with placebo. Upadacitinib's benefit/risk profile supports further development for treatment of CD. (Clinicaltrials.gov, Number: NCT02365649).

BACKGROUND: One of the therapy goals for Crohn's disease (CD) is glucocorticoid-free remission. Studies have shown care setting-specific variations in inflammatory bowel disease (IBD) management. AIMS: The principal objective of this study was to assess concordance between patient-reported and physician-reported outcomes in two different care settings (IBD centers and community practices). METHODS: Data of overall and long-term (≥ 3 months) glucocorticoid, immunosuppressant, and biologics use in participants ≥ 18 years old with a confirmed diagnosis of CD were collected. HCPs were grouped by IBD centers and community practices. Quality of life (using EuroQol 5D [EQ-5D]) and work/activity days lost were assessed. Agreement between patients' and HCPs' responses to survey questions was tested using kappa statistics. RESULTS: Data from 812 patients were examined. Significantly more patients versus HCPs reported oral glucocorticoid use (25.9% vs. 20.8%, κ = 0.735, P < 0.0001). Long-term use of oral glucocorticoids was similar for patients versus HCPs (67.7% vs. 63.8%, κ = 0.598, P = 0.53). Immunosuppressant use was 52.4% vs. 51.1% (κ = 0.784) and biologics use was 49.5% vs. 47.0% (κ = 0.909) for patients vs. HCPs. Patients and HCPs reported greater rates of symptom improvement with vs without biologic therapy (patients: 33.3% vs 16.8%; HCPs: 29.3% vs 13.5%, both P < 0.001). Patients with versus without routine follow-up were less likely to be treated with long-term glucocorticoid monotherapy (10.3% vs. 20.7%, P < 0.01) and had fewer lost work/activity days (5 vs. 8 days, P < 0.05). CONCLUSIONS: Patients reported more oral glucocorticoid use than physicians thought. Routine follow-up and higher rates of biologic use are associated with improvement in disease symptoms and general health among patients with CD.

BACKGROUND: Biomarkers of intestinal inflammation, such as faecal calprotectin and C-reactive protein, have been recommended for monitoring patients with Crohn's disease, but whether their use in treatment decisions improves outcomes is unknown. We aimed to compare endoscopic and clinical outcomes in patients with moderate to severe Crohn's disease who were managed with a tight control algorithm, using clinical symptoms and biomarkers, versus patients managed with a clinical management algorithm. METHODS: CALM was an open-label, randomised, controlled phase 3 study, done in 22 countries at 74 hospitals and outpatient centres, which evaluated adult patients (aged 18-75 years) with active endoscopic Crohn's disease (Crohn's Disease Endoscopic Index of Severity [CDEIS] >6; sum of CDEIS subscores of >6 in one or more segments with ulcers), a Crohn's Disease Activity Index (CDAI) of 150-450 depending on dose of prednisone at baseline, and no previous use of immunomodulators or biologics. Patients were randomly assigned at a 1:1 ratio to tight control or clinical management groups, stratified by smoking status (yes or no), weight (<70 kg or ≥70 kg), and disease duration (≤2 years or >2 years) after 8 weeks of prednisone induction therapy, or earlier if they had active disease. In both groups, treatment was escalated in a stepwise manner, from no treatment, to adalimumab induction followed by adalimumab every other week, adalimumab every week, and lastly to both weekly adalimumab and daily azathioprine. This escalation was based on meeting treatment failure criteria, which differed between groups (tight control group before and after random assignment: faecal calprotectin ≥250 µg/g, C-reactive protein ≥5mg/L, CDAI ≥150, or prednisone use in the previous week; clinical management group before random assignment: CDAI decrease of <70 points compared with baseline or CDAI >200; clinical management group after random assignment: CDAI decrease of <100 points compared with baseline or CDAI ≥200, or prednisone use in the previous week). De-escalation was possible for patients receiving weekly adalimumab and azathioprine or weekly adalimumab alone if failure criteria were not met. The primary endpoint was mucosal healing (CDEIS <4) with absence of deep ulcers 48 weeks after randomisation. Primary and safety analyses were done in the intention-to-treat population. This trial has been completed, and is registered with ClinicalTrials.gov, number NCT01235689. FINDINGS: Between Feb 11, 2011, and Nov 3, 2016, 244 patients (mean disease duration: clinical management group, 0·9 years [SD 1·7]; tight control group, 1·0 year [2·3]) were randomly assigned to monitoring groups (n=122 per group). 29 (24%) patients in the clinical management group and 32 (26%) patients in the tight control group discontinued the study, mostly because of adverse events. A significantly higher proportion of patients in the tight control group achieved the primary endpoint at week 48 (56 [46%] of 122 patients) than in the clinical management group (37 [30%] of 122 patients), with a Cochran-Mantel-Haenszel test-adjusted risk difference of 16·1% (95% CI 3·9-28·3; p=0·010). 105 (86%) of 122 patients in the tight control group and 100 (82%) of 122 patients in the clinical management group reported treatment-emergent adverse events; no treatment-related deaths occurred. The most common adverse events were nausea (21 [17%] of 122 patients), nasopharyngitis (18 [15%]), and headache (18 [15%]) in the tight control group, and worsening Crohn's disease (35 [29%] of 122 patients), arthralgia (19 [16%]), and nasopharyngitis (18 [15%]) in the clinical management group. INTERPRETATION: CALM is the first study to show that timely escalation with an anti-tumour necrosis factor therapy on the basis of clinical symptoms combined with biomarkers in patients with early Crohn's disease results in better clinical and endoscopic outcomes than symptom-driven decisions alone. Future studies should assess the effects of such a strategy on long-term outcomes such as bowel damage, surgeries, hospital admissions, and disability. FUNDING: AbbVie.

BACKGROUND AND AIMS: Centralized endoscopic scoring may reduce variability, but evidence is lacking in patients with Crohn's disease. We assessed the agreement of endoscopic scorings between site endoscopists and one central reader by using data from the adalimumab Crohn's disease clinical trial EXTEND. METHODS: Agreement between readers for Crohn's Disease Endoscopic Index of Severity (CDEIS)-scored endoscopies from 6 sites and Simple Endoscopic Score for Crohn's Disease (SES-CD)-scored endoscopies from 19 sites in EXTEND was evaluated at baseline and weeks 12 and 52. Agreement on total scores was calculated by using intraclass correlation coefficient (ICC). Kappa statistic or Spearman correlation coefficient measured the agreement between readers for each ileocolonic segment on CDEIS variables including deep ulceration, surface involved, and ulcerated surface and SES-CD variables including ulcerated surface, size of ulcers, and affected surface. RESULTS: ICCs on mean scores at baseline and weeks 12 and 52 were 0.78, 0.92, and 0.86 (CDEIS), and 0.77, 0.86, and 0.82 (SES-CD), respectively. Site endoscopists consistently reported higher scores. High agreement was observed for most segments and all time points for CDEIS variables and SES-CD large ulcers. Weak agreement occurred for the right side of the colon at all time points for CDEIS deep ulceration and SES-CD large ulcers and at baseline and week 12 for CDEIS ulcerated surface. Fair/moderate agreement occurred for SES-CD ulcerated surface and moderate/high agreement for affected surface for all segments and time points. CONCLUSIONS: Site and central readers showed high agreement on total CDEIS and SES-CD scores overall, whereas variability for individual segments was observed. Weakest agreement occurred at baseline, with a greater difference for SES-CD than for CDEIS score. ( CLINICAL TRIAL REGISTRATION NUMBER: NCT00348283.).

BACKGROUND & AIMS: Few studies have assessed the risk of malignancy from anti-tumor necrosis factor monotherapy or combination therapy for Crohn's disease (CD). We determined the relative risk of malignancy in patients with CD who received adalimumab monotherapy, compared with the general population. We also compared the risk of malignancy associated with combination adalimumab and immunomodulator therapy with that of adalimumab monotherapy. METHODS: We performed a pooled analysis of data from 1594 patients with CD who participated in clinical trials of adalimumab (CLASSIC I and II, CHARM, GAIN, EXTEND, and ADHERE studies; 3050 patient-years of exposure). We calculated rates of malignancy among patients; the expected rates of malignancy, based on the general population, were derived from the Surveillance, Epidemiology, and End Results registry and National Cancer Institute survey. RESULTS: Compared with the general population, patients receiving adalimumab monotherapy did not have a greater than expected incidence of nonmelanoma skin cancer (NMSC) or other cancers, whereas those receiving combination therapy had a greater than expected incidence of malignancies other than NMSC (standardized incidence ratio, 3.04; 95% confidence interval [CI], 1.66-5.10) and of NMSC (standardized incidence ratio, 4.59; 95% CI, 2.51-7.70). Compared with patients receiving adalimumab monotherapy, those patients receiving combination therapy had an increased risk of malignancy other than NMSC (relative risk, 2.82; 95% CI, 1.07-7.44) and of NMSC (relative risk, 3.46; 95% CI, 1.08-11.06). CONCLUSIONS: In patients with CD, the incidence of malignancy with adalimumab monotherapy was not greater than that of the general population. Co-administration of immunomodulator therapy and adalimumab was associated with an increased risk of NMSC and other cancers.

BACKGROUND & AIMS: Adalimumab is effective for induction and maintenance of remission in patients with moderate to severe ulcerative colitis (UC). We assessed whether adalimumab, in addition to standard UC therapy, reduced the risk for hospitalization (from all causes, from complications of UC, or from complications of UC or the drugs used to treat it) and colectomy in patients with moderate to severe UC compared with placebo. METHODS: Data were combined from patients that received induction therapy (a 160-mg dose followed by an 80-mg dose of adalimumab) or placebo in 2 trials (ULTRA 1 and ULTRA 2; n = 963). The risks of hospitalization and colectomy were compared between groups using unadjusted rates during the 8-week induction period, and patient-year-adjusted rates during 52 weeks. Statistical differences between groups were determined using the χ(2) method and Z score normal approximations. Numbers of hospitalizations were compared using Poisson regression with time offset. RESULTS: Significant reductions in risk of all-cause, UC-related, and UC- or drug-related hospitalizations (by 40%, 50%, and 47%, respectively; P < .05 for all comparisons) were observed within the first 8 weeks of adalimumab therapy compared with placebo. Significantly lower incidence rates for all-cause (0.18 vs 0.26; P = .03), UC-related (0.12 vs 0.22; P = .002), and UC- or drug-related (0.14 vs 0.24; P = .005) hospitalizations were observed during 52 weeks of adalimumab therapy compared with placebo. Rates of colectomy did not differ significantly between patients given adalimumab vs placebo. CONCLUSIONS: In patients with moderate to severe UC, the addition of adalimumab to standard of care treatment reduced the number of hospitalizations for any cause, as well as for UC-related and UC- or drug-related complications, compared with placebo.

BACKGROUND & AIMS: Behçet's disease is a chronic, relapsing inflammatory disease that can involve the mouth, skin, eyes, genitals, and intestines. Active intestinal Behçet's disease can be complicated by gastrointestinal (GI) bleeding and perforation. We performed a multicenter, open-label, uncontrolled study to evaluate the efficacy and safety of adalimumab, a fully human monoclonal antibody against tumor necrosis factor α, in patients with intestinal Behçet's disease who were refractory to corticosteroid and/or immunomodulator therapies. METHODS: The study was conducted at 12 sites in Japan, from November 2010 through October 2012. Twenty patients were given 160 mg adalimumab at the start of the study and 80 mg 2 weeks later, followed by 40 mg every other week for 52 weeks; for some patients, the dose was increased to 80 mg every other week. A composite efficacy index, combining GI symptom and endoscopic assessments, was used to evaluate efficacy. The primary efficacy end point was the percentage of patients with scores of 1 or lower for GI symptom and endoscopic assessments at week 24. Secondary end points included complete remission and resolution of non-GI Behçet's-related symptoms. RESULTS: Nine patients (45%) had GI symptom and endoscopic assessment scores of 1 or lower at week 24 of treatment, and 12 patients (60%) had these scores by week 52. Four patients (20%) achieved complete remission at weeks 24 and 52. Individual global GI symptom and endoscopic scores improved for most patients at weeks 24 and 52. Two thirds of patients with oral aphthous ulcers, skin symptoms, and genital ulcers, and 88% of patients with erythema nodosum had complete resolution of these conditions at week 52. A total of 9 of 13 patients (69%) taking steroids at baseline were able to taper (n = 1) or completely discontinue steroids (n = 8) during the study. No new safety signals were observed. CONCLUSIONS: Adalimumab is a potentially effective treatment for intestinal Behçet's disease in Japanese patients who are refractory to conventional treatments.

BACKGROUND & AIMS: Patients with moderate to severe ileocolonic Crohn's disease (CD) who received adalimumab induction and maintenance therapy had greater rates of mucosal healing than patients who received placebo after adalimumab induction therapy in a 52-week trial (EXTend the Safety and Efficacy of Adalimumab Through ENDoscopic Healing). We investigated whether this treatment also induced deep remission-a composite clinical and endoscopic end point. METHODS: Rates of deep remission, defined as the absence of mucosal ulceration and CD Activity Index scores less than 150, were compared between patients given continuous adalimumab and those given only induction therapy followed by placebo. We assessed the relationships between deep remission and other outcomes among patients who received adalimumab. The outcomes of patients with deep remission were compared with those of patients with only the absence of mucosal ulceration or only clinical remission. RESULTS: Rates of deep remission were 16% in patients given adalimumab vs 10% in those given placebo (P = .34) at week 12, and 19% vs 0% (P < .001) at week 52. Rates of deep remission were greatest among patients who received adalimumab and had CD for 2 years or less (33% at weeks 12 and 52). At week 52, patients who achieved deep remission at week 12 required significantly fewer adalimumab treatment adjustments, hospitalizations, and CD-related surgeries; had significantly less activity impairment; and had better quality of life and physical function compared with patients not achieving deep remission. Deep remission generally was associated with better outcomes than only an absence of mucosal ulceration; outcomes of patients with deep remission vs only clinical remission were similar. Deep remission was associated with estimated total cost savings of $10,360 (from weeks 12 through 52) compared with lack of deep remission. CONCLUSIONS: In an exploratory study of patients with moderate to severe ileocolonic CD who received adalimumab induction and maintenance therapy, patients achieving deep remission appeared to have better 1-year outcomes than those not achieving deep remission. These findings should be validated in large, prospective trials. ClinicalTrials.gov number: NCT00348283.

OBJECTIVES: The safety and efficacy of adalimumab for patients with moderately to severely active ulcerative colitis (UC) has been reported up to week 52 from the placebo-controlled trials ULTRA (Ulcerative Colitis Long-Term Remission and Maintenance with Adalimumab) 1 and 2. Up to 4 years of data for adalimumab-treated patients from ULTRA 1, 2, and the open-label extension ULTRA 3 are presented. METHODS: Remission per partial Mayo score, remission per Inflammatory Bowel Disease Questionnaire (IBDQ) score, and mucosal healing rates were assessed in adalimumab-randomized patients from ULTRA 1 and 2 up to week 208. Corticosteroid-free remission was assessed in adalimumab-randomized patients who used corticosteroids at lead-in study baseline. Maintenance of remission per partial Mayo score and mucosal healing was assessed in patients who entered ULTRA 3 in remission per full Mayo score and with mucosal healing, respectively. As observed, last observation carried forward (LOCF) and nonresponder imputation (NRI) were used to report efficacy. Adverse events were reported for any adalimumab-treated patient. RESULTS: A total of 600/1,094 patients enrolled in ULTRA 1 or 2 were randomized to receive adalimumab and included in the intent-to-treat analyses of the studies. Of these, 199 patients remained on adalimumab after 4 years of follow-up. Rates of remission per partial Mayo score, remission per IBDQ score, mucosal healing, and corticosteroid discontinuation at week 208 were 24.7%, 26.3%, 27.7% (NRI), and 59.2% (observed), respectively. Of the patients who were followed up in ULTRA 3 (588/1,094), a total of 360 patients remained on adalimumab 3 years later. Remission per partial Mayo score and mucosal healing after ULTRA 1 or 2 to year 3 of ULTRA 3 were maintained by 63.6% and 59.9% of patients, respectively (NRI). Adverse event rates were stable over time. CONCLUSIONS: Remission, mucosal healing, and improved quality of life were maintained in patients with moderately to severely active UC with long-term adalimumab therapy, for up to 4 years. No new safety signals were reported.

BACKGROUND & AIMS: Adalimumab is a fully human monoclonal antibody that binds tumor necrosis factor (TNF)-α. Its efficacy as maintenance therapy for patients with ulcerative colitis has not been studied in a controlled, double-blind trial. METHODS: Ulcerative colitis long-term remission and maintenance with adalimumab 2 (ULTRA 2) was a randomized, double-blind, placebo-controlled trial to evaluate the efficacy of adalimumab in induction and maintenance of clinical remission in 494 patients with moderate-to-severe ulcerative colitis who received concurrent treatment with oral corticosteroids or immunosuppressants. Patients were stratified based on prior exposure to TNF-α antagonists (either had or had not been previously treated with anti-TNF-α) and randomly assigned to groups given adalimumab 160 mg at week 0, 80 mg at week 2, and then 40 mg every other week or placebo. Primary end points were remission at weeks 8 and 52. RESULTS: Overall rates of clinical remission at week 8 were 16.5% on adalimumab and 9.3% on placebo (P = .019); corresponding values for week 52 were 17.3% and 8.5% (P = .004). Among anti-TNF-α naïve patients, rates of remission at week 8 were 21.3% on adalimumab and 11% on placebo (P = .017); corresponding values for week 52 were 22% and 12.4% (P = .029). Among patients who had previously received anti-TNF agents, rates of remission at week 8 were 9.2% on adalimumab and 6.9% on placebo (P = .559); corresponding values for week 52 were 10.2% and 3% (P = .039). Serious adverse events occurred in 12% of patients given adalimumab or placebo. Serious infections developed in 1.6% of patients given adalimumab and 1.9% given placebo. In the group given adalimumab, 1 patient developed squamous cell carcinoma and 1 developed gastric cancer. CONCLUSIONS: Adalimumab was safe and more effective than placebo in inducing and maintaining clinical remission in patients with moderate-to-severe ulcerative colitis who did not have an adequate response to conventional therapy with steroids or immunosuppressants.

BACKGROUND: Niacin extended-release (NER) is safe and effective for treatment of dyslipidemia. However, some patients discontinue NER treatment because of flushing, the most common adverse event associated with niacin therapy. OBJECTIVE: To evaluate the effect of daily oral acetylsalicylic acid (ASA) on NER-induced flushing in patients with dyslipidemia. METHODS: A randomized, double-blind, placebo-controlled, multicenter, 5-week study was conducted (ClinicalTrials.gov identifier: NCT00626392). Patients (n = 277) were randomly assigned to one of six treatment arms and received a 1-week run-in with ASA 325 mg or placebo followed by 4 weeks of ASA 325 mg or placebo 30 minutes before NER at a starting dose of 500 mg or 1000 mg; all patients were titrated to NER 2000 mg at week 3. The primary endpoint was the maximum severity of flushing events during week 1. RESULTS: In week 1, ASA run-in, ASA pretreatment, and a lower starting dosage of NER (500 mg/day) resulted in reductions in mean maximum severity of flushing; 48% fewer patients who received ASA experienced flushing episodes of moderate or greater intensity relative to placebo (absolute rates 15% vs 29%; p = 0.01). Over 4 weeks, ASA reduced the number of flushing episodes/patient/week by 42% relative to placebo. The discontinuation rate due to flushing was lower in the ASA group compared with placebo (1.8% vs 9.4%; p = 0.007). Overall safety was not different between groups. CONCLUSION: These data suggest that a clinically meaningful reduction in the severity and incidence of NER-induced flushing may be achieved with ASA use.

Background: Clinical trial endpoints for Crohn's disease (CD) activity correlate poorly with mucosal inflammation; to assess treatment efficacy, patient-reported outcomes and endoscopic assessments are preferred. This study assessed the impact on treatment efficacy estimations of using different definitions of clinical and endoscopic remission and endoscopic response, and of using site- or central-based endoscopy evaluation. Methods: This post hoc analysis of data fromEXTEND (extend the safety and efficacy of adalimumab through endoscopic healing), a placebo (PBO)-controlled, randomized trial of adalimumab (ADA) for mucosal healing, included adults with moderate-to-severe CD. Subsets of patients meeting specified Simplified Endoscopic Score for CD (SES-CD) inclusion criteria, according to site or central reading, and baseline stool frequency (SF) and/or abdominal pain score (AP) thresholds were evaluated. Various endpoint definitions based on the Crohn's Disease Activity Index (CDAI), its SF and AP components, SES-CD, and composite endpoints were compared between treatment groups. Results: Increased stringency of Week 12 clinical endpoints compared to CDAI<150 to SF≤3.0/1.5&AP≤1.0 reduced PBO response rates by ≥12% and increased treatment effects by ≤10%. Amending the SES-CD endpoint from ≤4 to ≤2 reduced the treatment effect from 24% to 8%. Composite endpoints further diminished response rates and effect sizes. Site-based evaluation was associated with lower remission rates versus central reading in the PBO group and, thus, greater ADA-related treatment effects. Conclusions: This analysis is the first to demonstrate that increasing the stringency of clinical and endoscopic endpoint definitions in CD trials, especially lowering SF or SES-CD definitions, reduces the ability to detect treatment-related change in CD activity; focus on endpoints that reflect clinical change is warranted.

BACKGROUND/AIMS: Intestinal Behçet's disease (BD) is an immune-mediated inflammatory disorder. We followed up the patients and evaluated safety profile and effectiveness of adalimumab for the treatment of intestinal BD through 100 weeks rolled over from the 52 week clinical trial (NCT01243671). METHODS: Patients initiated adalimumab therapy at 160 mg at week 0, followed by 80 mg at week 2, followed by 40 mg every other week until the end of the study. Long-term safety and all adverse events (AEs) were examined. The efficacy was assessed on the basis of marked improvement (MI) and complete remission (CR) using a composite efficacy index, which combined global gastrointestinal symptoms and endoscopic assessments. RESULTS: Twenty patients were enrolled in this study; 15 patients received adalimumab treatment until study completion. The incidence of AEs through week 100 was 544.4 events/100 person-years, which was comparable to the incidence through week 52 (560.4 events/100 person-years). No unexpected trend was observed and adalimumab was well tolerated. At weeks 52 and 100, 60.0% and 40.0% of patients showed MI, respectively, and 20.0% and 15.0% of patients showed CR, respectively. CONCLUSIONS: This report demonstrates 2 years safety and effectiveness of adalimumab in intestinal BD patients. Patients with intestinal BD refractory to conventional treatment receiving up to 2 years of adalimumab treatment demonstrated safety outcomes consistent with the known profile of adalimumab, and the treatment led to sustained reduction of clinical and endoscopic disease activity.
ABSTRACT
BACKGROUND: Growth failure is common in children with Crohn's disease. The effect of adalimumab (ADA), a fully human antitumor necrosis factor antagonist, on height velocity in pediatric patients with baseline (BL) linear growth impairment in the IMAgINE 1 trial is presented. METHODS: This analysis included female and male patients with growth potential (bone age ≤13 and ≤14 yr, respectively), with BL Pediatric Crohn's disease Activity Index >30, and who failed or were intolerant to conventional therapy. Patients received open-label induction ADA at weeks 0 and 2 by body weight (≥40 kg, 160 and 80 mg and <40 kg, 80 and 40 mg). At week 4, patients were randomized to double-blind high (40 or 20 mg for ≥40 kg or <40 kg) or low dose (20 or 10 mg for ≥40 kg or <40 kg) every other week ADA to week 52. Height velocity z-score was summarized at BL, week 26, and week 52 by patients with BL growth impairment (z-score ≤-1.0) or normal growth (z-score >-1.0). RESULTS: ADA therapy significantly improved and normalized growth rate at weeks 26 and 52 in patients with BL growth impairment (median z-score, BL, -3.25; week 26, -0.34; and week 52, 0.21; P < 0.001 versus BL for both), but not in patients with normal growth. Growth improvement was significantly greater at week 26 in week 4 responders to induction therapy compared with nonresponders (median z-score 0.09 versus -2.92; P = 0.02). CONCLUSIONS: ADA treatment resulted in growth rate normalization as early as week 26 in children with moderately to severely active Crohn's disease and growth impairment.

BACKGROUND AND AIMS: Randomised trials have described the benefits of adalimumab [ADA] for ulcerative colitis [UC]; however, few data are available on health-related quality of life [HRQL] and health care costs in clinical practice. METHODS: InspirADA, a multicentre, prospective study, evaluated the effect of ADA in patients with moderate to severe UC treated according to usual clinical practice. Outcomes assessed were: Simple Clinical Colitis Activity Index [SCCAI] response/remission rates; changes in HRQL; all-cause direct costs; and UC-related direct and indirect costs from baseline to Week 26. RESULTS: Data from 463 patients were analysed. At Week 26, 67% (95% confidence interval [CI]: 62%, 71%) of patients achieved response; 48% [95% CI: 44%, 53%] were in remission. For the overall population, significant [all p < 0.001] improvements from baseline to Week 26 were observed for the Short Inflammatory Bowel Disease Questionnaire [SIBDQ] (mean change ± standard deviation [SD]: 17.4 ± 14.5) and the European Quality of Life-5 Dimensions-5 Level [EQ-5D-5L] (index: 0.1 ± 0.2; visual analogue scale [VAS]: 19.5 ± 25.8). Parallel improvements were seen in work productivity [11% absolute decrease in absenteeism; 25% absolute decrease in impairment while working; and 27% absolute decrease in impairment of ability to perform daily activities, all p < 0.001]. Among study completers, cumulative all-cause medical costs and UC-related medical costs were significantly [both p < 0.001] reduced by 59% and 77%, respectively, 6 months after initiation of therapy compared with the preceding 6 months. The safety profile of ADA was consistent with that observed in previous clinical trials. CONCLUSIONS: ADA therapy in usual clinical practice is effective at improving and maintaining symptomatic control, improving HRQL, and decreasing costs of medical care among patients with UC.

BACKGROUND: IMAgINE 1 assessed 52-week efficacy and safety of adalimumab in children with moderate to severe Crohn's disease. Long-term efficacy and safety of adalimumab for patients who entered the IMAgINE 2 extension are reported. METHODS: Patients who completed IMAgINE 1 could enroll in IMAgINE 2. Endpoints assessed from weeks 0 to 240 of IMAgINE 2 were Pediatric Crohn's Disease Activity Index remission (Pediatric Crohn's Disease Activity Index ≤ 10) and response (Pediatric Crohn's Disease Activity Index decrease ≥15 from IMAgINE 1 baseline) using observed analysis and hybrid nonresponder imputation (hNRI). For hNRI, discontinued patients were imputed as failures unless they transitioned to commercial adalimumab (with study site closure) or adult care, where last observation was carried forward. Corticosteroid-free remission in patients receiving corticosteroids at IMAgINE 1 baseline, discontinuation of immunomodulators (IMMs) in patients receiving IMMs at IMAgINE 2 baseline, and linear growth improvement were reported as observed. Adverse events were assessed for patients receiving ≥1 adalimumab dose in IMAgINE 1 and 2 through January 2015. RESULTS: Of 100 patients enrolled in IMAgINE 2, 41% and 48% achieved remission and response (hNRI) at IMAgINE 2 week 240. Remission rates were maintained by 45% (30/67, hNRI) of patients who entered IMAgINE 2 in remission. At IMAgINE 2 week 240, 63% (12/19) of patients receiving corticosteroids at IMAgINE 1 baseline achieved corticosteroid-free remission and 30% (6/20) of patients receiving IMMs at IMAgINE 2 baseline discontinued IMMs. Adalimumab treatment led to growth velocity normalization. No new safety signals were identified. CONCLUSIONS: Efficacy and safety profiles of prolonged adalimumab treatment in children with Crohn's disease were consistent with IMAgINE 1 and adult Crohn's disease adalimumab trials.

BACKGROUND: The efficacy of adalimumab in inducing and maintaining remission in children with moderately to severely active Crohn's disease was shown in the IMAgINE 1 trial (NCT00409682). As per protocol, nonresponders or patients experiencing flare(s) on every other week (EOW) maintenance dosing could escalate to weekly dosing; we aimed to determine the therapeutic benefits of weekly dose escalation in this subpopulation. METHODS: Week 52 remission and response rates were assessed in patients who escalated to weekly dosing from their previous EOW schedule, which was according to randomized treatment dose (higher dose [HD] adalimumab [≥40 kg, 40 mg EOW; <40 kg, 20 mg EOW] or lower dose [LD; ≥40 kg, 20 mg EOW; <40 kg, 10 mg EOW]). Adverse events were reported for patients remaining on EOW dosing and patients receiving weekly dosing. RESULTS: Escalation to weekly dosing occurred in 48/95 (50.5%) patients randomized to LD and 35/93 (37.6%) patients randomized to HD adalimumab (P = 0.076). Week 52 remission and response rates were 18.8% and 47.9% for patients receiving LD adalimumab weekly and 31.4% and 57.1% for patients receiving HD adalimumab weekly, respectively (LD versus HD, P = 0.19 for remission; P = 0.41 for response). Adverse event rates were similar for patients receiving EOW and weekly adalimumab. CONCLUSIONS: Weekly adalimumab dosing was clinically beneficial for children with Crohn's disease who experienced nonresponse or flare on EOW dosing. No increased safety risks were observed with weekly dosing.

BACKGROUND/AIMS: This was a Phase 2 study (NCT02015793) to evaluate the pharmacokinetics, safety, and efficacy of adalimumab in Chinese patients with Crohn's disease (CD). METHODS: Thirty, adult Chinese patients with CD (CD Activity Index [CDAI] 220-450; high-sensitivity [hs]-C-reactive protein [CRP] ≥3 mg/L) received double-blind adalimumab 160/80 mg or 80/40 mg at weeks 0/2, followed by 40 mg at weeks 4 and 6. An open-label extension period occurred from weeks 8-26; patients received 40 mg adalimumab every other week. Serum adalimumab concentration and change from baseline in fecal calprotectin (FC) were measured during the double-blind period. Clinical remission (CDAI <150), response (decrease in CDAI ≥70 points from baseline), and change from baseline in hs-CRP were assessed through week 26. Nonresponder imputation was used for missing categorical data and last observation carried forward for missing hs-CRP/FC values. No formal hypothesis was tested. Adverse events were monitored. RESULTS: Mean adalimumab serum concentrations during the induction phase were 13.9-18.1 µg/mL (160/80 mg group) and 7.5-9.5 µg/mL (80/40 mg group). During the double-blind period, higher remission/response rates and greater reductions from baseline in hs-CRP and FC were observed with adalimumab 160/80 mg compared to that with 80/40 mg. Adverse event rates were similar among all treatment groups. CONCLUSIONS: Adalimumab serum concentrations in Chinese patients with CD were comparable to those observed previously in Western and Japanese patients. Clinically meaningful remission rates and improvement in inflammatory markers were achieved with both dosing regimens; changes occurred rapidly with adalimumab 160/80 mg induction therapy. No new safety signals were reported.
ABSTRACT
BACKGROUND: Adalimumab, a fully human monoclonal antibody (IgG1κ) to tumor necrosis factor, has shown benefit in the treatment of inflammatory bowel disease. The purpose of this analysis was to evaluate the pharmacokinetics (PK) and the serum concentration-efficacy relationship of adalimumab in pediatric patients with moderate-to-severe Crohn's disease. METHODS: The safety, efficacy, and PK of adalimumab was evaluated in a phase-3, randomized, double-blind, 52-week study (IMAgINE-1, N = 192), which had a 4-week open-label induction phase (dose was determined by patient weight) followed by a 48-week double-blind maintenance phase (standard and low-dose arms, drug given every other week). Trough serum adalimumab (baseline, weeks 2, 4, 16, 26, and 52) and anti-adalimumab antibody measurements (baseline, weeks 16, 26, and 52) were collected. Disease activity was assessed using the Pediatric Crohn's Disease Activity Index. RESULTS: At week 52, adalimumab trough concentrations (mean ± SD) were higher for patients in the standard-dose (9.48 ± 5.61 µg/mL) compared with the low-dose (3.51 ± 2.21 µg/mL) arm. In patients whose doses were increased from every other week to weekly, higher trough concentrations were observed after dose escalation. Higher body weight, baseline C-reactive protein, and lower baseline albumin levels were associated with greater clearance of adalimumab. An exposure (serum concentration)-efficacy relationship was observed, in which higher concentrations of adalimumab were associated with greater rates of remission. CONCLUSIONS: This study is the first to describe the PK of adalimumab in pediatric patients with moderate-to-severe Crohn's disease. A positive association between serum adalimumab concentration and remission/response was identified.

BACKGROUND: Adalimumab is a fully human, monoclonal antibody against tumor necrosis factor that is approved in Western countries for the treatment of moderately to severely active ulcerative colitis (UC). METHODS: This 52-week, phase 2/3, randomized, double-blind study evaluated adalimumab for induction and maintenance treatment in 273 anti-TNF-naive Japanese patients with UC who were refractory to corticosteroids, immunomodulators, or both. Patients received placebo, adalimumab 80/40 (80 mg at week 0, then 40 mg every other week), or adalimumab 160/80 (160/80 mg at weeks 0/2, then 40 mg every other week) in addition to background UC therapy. RESULTS: At week 8, remission rates were similar among treatment arms, but more patients treated with adalimumab 160/80 achieved response (placebo, 35 %; 80/40, 43 %; 160/80, 50 %; P = 0.044 for 160/80 vs placebo) and mucosal healing (placebo, 30 %; 80/40, 39 %; 160/80, 44 %; P = 0.045 for 160/80 vs placebo) compared with placebo. At week 52, more patients receiving adalimumab 40 mg every other week achieved response (18 vs 31 %; P = 0.021), remission (7 vs 23 %; P = 0.001), and mucosal healing (16 vs 29 %; P = 0.015) compared with placebo. Week 8 response to adalimumab was associated with greater rates of response (61 %), remission (46 %), and mucosal healing (57 %) at week 52 relative to the overall population. Rates of serious adverse events were similar between treatment arms. CONCLUSIONS: Induction with adalimumab 160/80 mg led to early response and mucosal healing. Maintenance adalimumab had greater rates of long-term response, remission, and mucosal healing compared with placebo. No new safety signals were identified.
