Efficacy and Safety of Upadacitinib in a Randomized Trial of Patients With Crohn's Disease.

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).

Healthcare Providers Underestimate Patients' Glucocorticoid Use in Crohn's Disease.

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.

Effect of tight control management on Crohn's disease (CALM): a multicentre, randomised, controlled phase 3 trial.

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.

Lymphoma Risk and Overall Safety Profile of Adalimumab in Patients With Crohn's Disease With up to 6 Years of Follow-Up in the Pyramid Registry.

OBJECTIVES: Real-world, prospective, long-term studies in Crohn's disease (CD) characterizing adalimumab safety data and lymphoma risk were lacking. We present the final results from the PYRAMID registry, which was designed to rule out a doubling of lymphoma risk in adalimumab-treated patients with CD. METHODS: Patients with moderately to severely active CD newly prescribed or currently receiving adalimumab according to local product labels were followed for up to 6 years and analyzed for adverse events (AEs). The registry exposure-adjusted observed rate of lymphoma was compared with the estimated background lymphoma rate from a sex-matched general population in the Surveillance, Epidemiology, and End Results 17 Registry database adjusted for anticipated prior or concurrent thiopurine use in a CD population. RESULTS: A total of 5025 patients were evaluated (16680.4 PY of adalimumab registry exposure, ≈3 years/patient mean follow-up). Registry treatment-emergent AEs included 4129 serious AEs (n = 1853 [36.9%]; 24.8 E/100 PY), 792 serious infections (n = 556 [11.1%]; 4.7 E/100 PY), and 134 malignancies (n = 116 [2.3%]; 0.8 E/100 PY), including ten lymphomas. The observed lymphoma rate (0.060 E/100 PY) was lower than the estimated background rate (0.084 E/100 PY), and the upper bound of the one-sided 95% CI of the observed rate (0.102 E/100 PY) was lower than double the estimated rate (0.168 E/100 PY). CONCLUSIONS: PYRAMID is the longest prospective adalimumab study in routine clinical practice, with up to 6 years of follow-up. No new safety signals were reported. The pre-specified registry objective of ruling out a doubling of lymphoma risk with adalimumab was met.

Agreement of site and central readings of ileocolonoscopic scores in Crohn's disease: comparison using data from the EXTEND trial.

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.).

Direct Costs in Patients with Celiac Disease in the USA: A Retrospective Claims Analysis.

BACKGROUND: Celiac disease (CeD) is an autoimmune disease triggered by gluten ingestion. AIM: We assessed total direct costs burden associated with CeD in patients with CeD versus patients without CeD using administrative claims data. METHODS: Patients with CeD (cases) with ≥1 occurrences of CeD diagnosis were selected at a randomly chosen date (index date) from the OptumHealth Reporting and Insights database from 01/01/1998 through 03/31/2013. Cases were continuously enrolled throughout baseline (1 year before index date) and study (1 year after index date) periods. Cases were categorized as full remission and partial remission and matched 1:1 based on age, sex, region, index date, company, and employment status. Total all-cause and CeD-related costs were calculated. RESULTS: A total of 12,187 cases were matched with an equal number of controls. Mean total all-cause costs were $12,217 in cases versus $4935 in controls (P < 0.0001). In full remission (N = 10,181 [83.5 %]) and partial remission (N = 2006 [16.5 %]) cases, mean total all-cause direct costs (cases versus controls) were $11,038 versus $4962 and $18,206 versus $4796, respectively. All-cause medical costs ($9839 for all cases, $8723 for full remission cases, $15,499 for partial remission cases) accounted for the majority of all-cause total costs and included outpatient costs ($6675; $6456; and $7785, respectively) and hospitalizations ($2776; $1963; and $6906, respectively). CeD-related medical costs were 13 and 27 % of all-cause medical costs for all cases and partial remission cases, respectively. CONCLUSIONS: Patients with CeD and partial remission of CeD incurred significantly higher (2.5 and 3.8 times) total all-cause costs compared with matched controls.

Increased risk of malignancy with adalimumab combination therapy, compared with monotherapy, for Crohn's disease.

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.

Adalimumab therapy is associated with reduced risk of hospitalization in patients with ulcerative colitis.

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.

Adalimumab for the treatment of Japanese patients with intestinal Behçet's disease.

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. ClinicalTrials.gov number: NCT01243671.

Adalimumab induces deep remission in patients with Crohn's disease.

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.

Four-year maintenance treatment with adalimumab in patients with moderately to severely active ulcerative colitis: Data from ULTRA 1, 2, and 3.

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.

Adalimumab induces and maintains clinical remission in patients with moderate-to-severe ulcerative colitis.

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.

Adalimumab for induction of clinical remission in moderately to severely active ulcerative colitis: results of a randomised controlled trial.

OBJECTIVE: The aim of this study was to assess the efficacy and safety of adalimumab (ADA), a recombinant human monoclonal antibody against tumour necrosis factor α (TNF), for the induction of clinical remission in anti-TNF naïve patients with moderately to severely active ulcerative colitis. METHODS: This 8-week, multicentre, randomised, double-blind, placebo-controlled study (NCT00385736), conducted at 94 centres in North America and Europe, enrolled ambulatory adult patients with Mayo score of ≥ 6 points and endoscopic subscore of ≥ 2 points despite treatment with corticosteroids and/or immunosuppressants. Under the original study protocol, 186 patients were randomised (1:1) to subcutaneous treatment with ADA160/80 (160 mg at week 0, 80 mg at week 2, 40 mg at weeks 4 and 6) or placebo. Subsequently, at the request of European regulatory authorities, the protocol was amended to include a second induction group (ADA80/40: 80 mg at week 0, 40 mg at weeks 2, 4 and 6). The primary efficacy endpoint was clinical remission (Mayo score ≤ 2 with no individual subscore >1) at week 8, assessed in 390 patients randomised (1:1:1) to ADA160/80, ADA80/40, or placebo. Safety was assessed in all enrolled patients. Patients, study site personnel, investigators, and the sponsor were blinded to treatment assignment. RESULTS: At week 8, 18.5% of patients in the ADA160/80 group (p = 0.031 vs placebo) and 10.0% in the ADA80/40 group (p = 0.833 vs placebo) were in remission, compared with 9.2% in the placebo group. Serious adverse events occurred in 7.6%, 3.8% and 4.0% of patients in the placebo, ADA80/40, and ADA160/80 groups, respectively. There were two malignancies in the placebo group, none in the ADA groups. There were no cases of tuberculosis and no deaths. CONCLUSIONS: ADA160/80 was safe and effective for induction of clinical remission in patients with moderately to severely active ulcerative colitis failing treatment with corticosteroids and/or immunosuppressants. Clinical trial NCT00385736.

Levosimendan vs. dobutamine: outcomes for acute heart failure patients on beta-blockers in SURVIVE.

AIMS: Many chronic heart failure (CHF) patients take beta-blockers. When such patients are hospitalized for decompensation, it remains unclear how ongoing beta-blocker treatment will affect outcomes of acute inotrope therapy. We aimed to assess outcomes of SURVIVE patients who were on beta-blocker therapy before receiving a single intravenous infusion of levosimendan or dobutamine. METHODS AND RESULTS: Cox proportional hazard regression revealed all-cause mortality benefits of levosimendan treatment over dobutamine when the SURVIVE population was stratified according to baseline presence/absence of CHF history and use/non-use of beta-blocker treatment at baseline. All-cause mortality was lower in the CHF/levosimendan group than in the CHF/dobutamine group, showing treatment differences by hazard ratio (HR) at days 5 (3.4 vs. 5.8%; HR, 0.58, CI 0.33-1.01, P = 0.05) and 14 (7.0 vs. 10.3%; HR, 0.67, CI 0.45-0.99, P = 0.045). For patients who used beta-blockers (n = 669), mortality was significantly lower for levosimendan than dobutamine at day 5 (1.5 vs. 5.1% deaths; HR, 0.29; CI 0.11-0.78, P = 0.01). CONCLUSION: Levosimendan may be better than dobutamine for treating patients with a history of CHF or those on beta-blocker therapy when they are hospitalized with acute decompensations. These findings are preliminary but important for planning future studies.

Acetylsalicylic acid reduces niacin extended-release-induced flushing in patients with dyslipidemia.

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.

Flushing ASsessment Tool (FAST): psychometric properties of a new measure assessing flushing symptoms and clinical impact of niacin therapy.

BACKGROUND AND OBJECTIVE: A common adverse effect of niacin therapy is flushing, manifested by cutaneous warmth, redness, itching and/or tingling. The Flushing ASsessment Tool (FAST) was developed to assess flushing symptoms and their impact on patients receiving niacin therapy. This study evaluated the reliability, validity and responsiveness of the FAST. The minimal important difference (MID) of the FAST was also examined. METHODS: This was a prospective, randomized, double-blind, placebo-controlled, parallel-group 8-week study conducted to evaluate the psychometric characteristics of the FAST. The instrument is administered daily using an electronic patient diary. The study was conducted at 41 clinical sites in the US. 276 patients with dyslipidaemia were randomized to treatment and were at least 18 years of age, with fasting laboratory values of low-density lipoprotein cholesterol (LDL-C) <250 mg/dL and one of the following: high-density lipoprotein cholesterol (HDL-C) <40 mg/dL for males or <50 mg/dL for females; or triglycerides (TG) > or = 150 and < or = 400 mg/dL; or LDL-C > or = 70 mg/dL for patients with a history of coronary heart disease (CHD) or CHD risk equivalents, or > or = 100 mg/dL for subjects with two risk factors, or > or = 160 mg/dL for subjects with 0-1 risk factors. Patients were randomized (1 : 1 : 1) to receive niacin extended-release (NER) 500 mg/day in week 1, 1000 mg/day in week 2 and 2000 mg/day in weeks 3-6/aspirin (acetylsalicylic acid [ASA]), NER/ASA placebo, or NER placebo/ASA placebo. RESULTS: FAST test-retest reliability in stable patients during the first 2 weeks was demonstrated for overall flushing severity using patient and physician overall treatment effect (OTE) ratings (intraclass correlation coefficients of >0.7 for mean overall and individual flushing severity scores). Over the 6-week treatment period, FAST scores demonstrated significant correlations with individual symptoms, impact on daily activities and sleep, and dissatisfaction related to flushing (p < 0.01). Changes in FAST scores were associated with treatment satisfaction (p < 0.01) and patient- and physician-rated OTE (p < 0.01). Using patient-rated OTE, the mean maximum flushing severity scores improved 1.85 points in responders and only 0.18 points in non-responders (p < 0.001); responders were defined by improved patient- or physician-rated OTE. Among patients with flushing, mean maximum overall flushing scores differed between patients who subsequently discontinued due to flushing (7.9 points) and those who did not discontinue (4.7 points; p < 0.001). The probable range in this study for a detectable change in flushing symptoms (MID) was 0.29-0.38 points for mean flushing severity and 0.66-0.86 points for maximum flushing severity. CONCLUSION: The FAST exhibited test-retest reliability, good evidence of construct validity, and, overall, flushing severity was responsive to change over time. The FAST is a reliable and valid instrument for assessing the impact of niacin-induced flushing in patients with dyslipidaemia.

Adalimumab Effectiveness Up to Six Years in Adalimumab-naïve Patients with Crohn's Disease: Results of the PYRAMID Registry.

BACKGROUND: PYRAMID was an international multicenter, noninterventional, postmarketing registry assessing long-term safety and effectiveness of adalimumab (Humira), as used in routine clinical practice. METHODS: Adult patients with moderately to severely active Crohn's disease with or without prior adalimumab experience were enrolled in the registry and followed for up to 6 years. Effectiveness measurements included the Physician's Global Assessment (PGA, a composite of Harvey Bradshaw Index [HBI] and rectal bleeding score), clinical remission (HBI < 5), Short Inflammatory Bowel Disease Questionnaire (SIBDQ), and Work Productivity and Activity Impairment (WPAI) questionnaire. Data were reported for adalimumab-naïve patients and analyzed by baseline immunomodulator use and disease duration. RESULTS: This study evaluated 2057 adalimumab-naïve patients. Mean PGA improved from 7.5 (baseline) to 3.9 (year 1) and 3.3 (year 6). The proportion of patients in HBI remission increased from 29% (573 of 1969; baseline) to 68% (900 of 1331; year 1) and 75% (625 of 831; year 6). Patients stratified by baseline immunomodulator use had similar HBI remission rates; patients with disease duration <2 years achieved numerically higher HBI remission rates than patients with longer disease duration. Patient-reported SIBDQ and WPAI scores improved at year 1; all WPAI subscore improvements were clinically meaningful (≥7% point change) at year 1 and maintained through year 6. Serious infections were reported in 11.1% of patients; incidence rates of malignancies, lymphoma, and demyelinating disorders were low. CONCLUSION: Adalimumab therapy, as used in routine clinical practice, improved physician-reported and patient-reported disease outcomes and remission rates for up to 6 years. No new safety signals were observed.

Performance of Crohn's disease Clinical Trial Endpoints based upon Different Cutoffs for Patient Reported Outcomes or Endoscopic Activity: Analysis of EXTEND Data.

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.

Efficacy and Safety of Dose Escalation to Adalimumab 80 mg Every Other Week in Japanese Patients with Crohn's Disease Who Lost Response to Maintenance Therapy.

BACKGROUND: Dose escalation is often recommended for loss of response in anti-TNFα-treated patients with Crohn's disease (CD). This 52-week phase 3, multicenter study investigated the efficacy and safety of escalation to adalimumab 80 mg every other week (EOW) in Japanese patients with CD who lost response to maintenance adalimumab 40 mg EOW. METHODS: Twenty-eight patients aged ≥15 years with moderately to severely active CD who had previously attained and subsequently lost clinical response to maintenance ada limumab received open-label adalimumab 80 mg EOW during weeks 0-50. Loss of response was defined as CD activity index (CDAI) ≥200, increases in CDAI ≥50 from minimum observed value, and C-reactive protein (CRP) ≥1 mg/dL at screening. The primary endpoint was the proportion of patients achieving a CDAI decrease ≥50 (CR-50) from baseline at week 8. RESULTS: At weeks 8 and 52, 75.0 and 57.1$ of patients achieved CR-50 and 25.0 and 35.7$ achieved clinical remission (CDAI < 150), respectively; median CRP changes from baseline were -0.39 and -0.77 mg/dL, respectively. Most treatment-emergent adverse events were mild to moderate. CONCLUSIONS: Adalimumab dose escalation to 80 mg EOW improved CD activity in patients who had lost response to maintenance adalimumab, with no new safety signals.

Levosimendan vs dobutamine for patients with acute decompensated heart failure: the SURVIVE Randomized Trial.

CONTEXT: Because acute decompensated heart failure causes substantial morbidity and mortality, there is a need for agents that at least improve hemodynamics and relieve symptoms without adversely affecting survival. OBJECTIVE: To assess the effect of a short-term intravenous infusion of levosimendan or dobutamine on long-term survival. DESIGN, SETTING, AND PATIENTS: The Survival of Patients With Acute Heart Failure in Need of Intravenous Inotropic Support (SURVIVE) study was a randomized, double-blind trial comparing the efficacy and safety of intravenous levosimendan or dobutamine in 1327 patients hospitalized with acute decompensated heart failure who required inotropic support. The trial was conducted at 75 centers in 9 countries and patients were randomized between March 2003 and December 2004. INTERVENTIONS: Intravenous levosimendan (n = 664) or intravenous dobutamine (n = 663). MAIN OUTCOME MEASURE: All-cause mortality at 180 days. RESULTS: All-cause mortality at 180 days occurred in 173 (26%) patients in the levosimendan group and 185 (28%) patients in the dobutamine group (hazard ratio, 0.91; 95% confidence interval, 0.74-1.13; P = .40). The levosimendan group had greater decreases in B-type natriuretic peptide level at 24 hours that persisted through 5 days compared with the dobutamine group (P<.001 for all time points). There were no statistical differences between treatment groups for the other secondary end points (all-cause mortality at 31 days, number of days alive and out of the hospital, patient global assessment, patient assessment of dyspnea at 24 hours, and cardiovascular mortality at 180 days). There was a higher incidence of cardiac failure in the dobutamine group. There were higher incidences of atrial fibrillation, hypokalemia, and headache in the levosimendan group. CONCLUSION: Despite an initial reduction in plasma B-type natriuretic peptide level in patients in the levosimendan group compared with patients in the dobutamine group, levosimendan did not significantly reduce all-cause mortality at 180 days or affect any secondary clinical outcomes.
