Pharmacokinetic Features and Presence of Antidrug Antibodies Associate With Response to Infliximab Induction Therapy in Patients With Moderate to Severe Ulcerative Colitis. Clin Gastroenterol Hepatol 2016; 14:251-8.e1-2. [PMID: 26545802 DOI: 10.1016/j.cgh.2015.10.029] [Citation(s) in RCA: 142] [Impact Index Per Article: 17.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2015] [Revised: 10/02/2015] [Accepted: 10/05/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS The pharmacokinetics of infliximab during induction treatment for ulcerative colitis (UC) have not been studied. We investigated serum concentrations of infliximab and the early appearance of antibodies to infliximab (ATI) during induction treatment in patients with moderate-to-severe UC. METHODS We performed a prospective analysis of 19 consecutive patients with moderate-severe UC (endoscopic Mayo ≥ 2) receiving induction therapy with infliximab (5 mg/kg at weeks 0, 2, and 6) at 2 centers in Amsterdam, The Netherlands, from July 2012 through March 2014. Serial serum and fecal samples were collected for 6 weeks and concentrations of infliximab, ATI, c-reactive protein (CRP), albumin, and fecal calprotectin were measured. Treatment success was defined as endoscopic response (≥ 1 point reduction in the endoscopic Mayo score) at week 8. RESULTS Eleven patients (58%) had an endoscopic response. The median serum concentrations of infliximab at week 6 were 8.1 μg/mL in responders (interquartile range, 3.0-13.7 μg/mL) and 2.9 μg/mL in nonresponders (interquartile range, 0.01-5.8 μg/mL) (P = .03). ATIs were detected in 7 patients as early as day 18 (median, 28 d; interquartile range, 18-42 d). Six of the 8 nonresponders tested positive for ATIs vs 1 of 11 responders (P < .01; odds ratio, 30.0; 95% CI, 2.2-406.2). Patients with a baseline concentration of CRP greater than 50 mg/L had lower drug exposure from weeks 0 to 6 (587 mg/L/d in patients with high levels of CRP vs 1361 mg/L/day in patients with low CRP; P = .001). The median area under the curve for serum concentration of infliximab during induction therapy was 1230 mg/L/d in nonresponders vs 1352 mg/L/d in responders (P = .65). CONCLUSIONS There is a significant difference in serum concentration of infliximab at week 6 of treatment between responders and nonresponders. Early development of ATIs during induction therapy reduces the serum concentration of infliximab and is associated with nonresponse to treatment. Patients with high baseline serum levels of CRP had lower serum concentrations of infliximab. CLINICAL TRIAL NUMBER NL39626.018.12.

Abstract
BACKGROUND Acute severe ulcerative colitis (ASUC) is a life-threatening condition for which optimal management strategies remain ill-defined. AIM To review the evidence regarding the natural history, diagnosis, monitoring and treatment of ASUC to inform an evidence-based approach to management. METHODS Relevant articles addressing the management of ASUC were identified from a search of MEDLINE, the Cochrane Library and conference proceedings. RESULTS Of ASUC, 31-35% is steroid-refractory. Infliximab and ciclosporin salvage therapies have improved patient outcomes in randomised controlled trials. Short-term response rates (within 3 months) have ranged from 40% - 54% for ciclosporin and 46-83% for infliximab. Long-term clinical response rates (≥1 year) have ranged from 42%-50% for ciclosporin and 50-65% for infliximab. Short-term and long-term colectomy rates have been respectively: 26-47% and 36-58% for ciclosporin, and 0-50% and 35-50% for infliximab. Mortality rates for ciclosporin and infliximab-treated patients have been: 0-5% and 0-2%, respectively. At present, management challenges include the selection, timing and assessment of response to salvage therapy, utilisation of therapeutic drug monitoring and long-term maintenance of remission. CONCLUSIONS Optimal management of acute severe ulcerative colitis should be guided by risk stratification using predictive indices of corticosteroid response. Timely commencement and assessment of response to salvage therapy is critical to reducing morbidity and mortality. Emerging pharmacokinetic models and therapeutic drug monitoring may assist clinical decision-making and facilitate a shift towards individualised acute severe ulcerative colitis therapies.

Abstract
BACKGROUND Nonresponse and loss of response to anti-TNF therapies in Crohn's disease represent significant clinical problems for which clear management guidelines are lacking. AIM To review the incidence, mechanisms and predictors of primary nonresponse and secondary loss of response to formulate practical clinical algorithms to guide management. METHODS Through a systematic literature review, 503 articles were identified which fit the inclusion criteria. RESULTS Primary nonresponse to anti-TNF treatment affects 13-40% of patients. Secondary loss of response to anti-TNF occurs in 23-46% of patients when determined according to dose intensification, and 5-13% of patients when gauged by drug discontinuation rates. Recent evidence suggests that the mechanisms underlying primary nonresponse and secondary loss of response are multifactorial and include disease characteristics (phenotype, location, severity); drug (pharmacokinetic, pharmacodynamic or immunogenicity) and treatment strategy (dosing regimen) related factors. Clinical algorithms that employ therapeutic drug monitoring (using anti-TNF tough levels and anti-drug antibody levels) may be used to determine the underlying cause of primary nonresponse and secondary loss of response respectively and guide clinicians as to which patients are most likely to respond to anti-TNF therapy and help optimise drug therapy for those who are losing response to anti-TNF therapy. CONCLUSIONS Nonresponse or loss of response to anti-TNF occurs commonly in Crohn's disease. Clinical algorithms utilising therapeutic drug monitoring may establish the mechanisms for treatment failure and help guide the subsequent therapeutic approach.

Predictors of Thiopurine Treatment Failure in Biologic-Naïve Ulcerative Colitis Patients. Dig Dis Sci 2016; 61:230-7.

Abstract
INTRODUCTION Thiopurines (azathioprine and 6-mercaptopurine) have been used in the management of UC patients for over three decades. Nearly half of patients with UC treated with thiopurines fail to achieve remission or lose remission during treatment. Factors associated with thiopurine failure are poorly understood. The primary aim of our study was to investigate patient-related factors which are associated with thiopurine failure. METHODS TNF-alpha antagonist-naïve patients with histological diagnosis of UC, receiving thiopurine therapy, with follow-up data from 1 to 3 years were included in the study. Data regarding demographics, laboratory results, and disease characteristics were collected. The primary endpoint was failure of thiopurine therapy, defined as treatment with steroids, therapeutic escalation to TNF-alpha antagonist therapy, or need for surgery. RESULTS Of the 563 patients identified using ICD-9 codes, 78 TNF-alpha antagonist-naïve patients with a histological diagnosis of UC, receiving thiopurine treatment, were identified. Over the three-year follow-up period, 38 patients failed thiopurine treatment. On adjusted Cox regression, BMI < 25 kg/m(2) (HR 3, 95 % CI 1.55-5.83; p value = 0.001) was significantly associated with thiopurine failure. Furthermore, although not statistically significant, there was a strong trend toward thiopurine failure among patients with serum albumin level < 4 g/dL (HR 1.98, 95 % CI 0.97-4; p value = 0.06), non-smoking status (HR 2.2, 95 % CI 0.96-5.06; p value = 0.06), and higher degree of colon inflammation (HR 1.49, 95 % CI 0.96-2.32; p value = 0.08). DISCUSSION Our results show that low body mass index is associated with increased risk of failure of thiopurine treatment. Furthermore, there was a strong trend toward thiopurine failure among patients with low serum albumin level (<4gm/dL). These factors should be considered as markers of non-response to thiopurine monotherapy for patients with moderately severe ulcerative colitis.

A Matrix-based Model Predicts Primary Response to Infliximab in Crohn's Disease. J Crohns Colitis 2015; 9:1120-6.

Abstract
BACKGROUND Prediction of primary non-response [PNR] to anti-tumour necrosis factors [TNFs] in inflammatory bowel disease [IBD] is direly needed to select the optimal therapeutic class for a given patient. We developed a matrix-based prediction tool to predict response to infliximab [IFX] in Crohn's disease [CD] patients. METHODS This retrospective single-centre study included 201 anti-TNF naïve CD patients who started with IFX induction therapy. PNR occurred in 16 [8%] patients. Clinical, biological [including serum TNF and the IBD serology 6 panel and genetic [the 163 validated IBD risk loci] markers were collected before start. Based on the best fitted regression model, probabilities of primary response to IFX were calculated and arranged in a prediction matrix tool. RESULTS Multiple logistic regression withheld three final independent predictors [p < 0.05] for PNR: age at first IFX, {odds ratio (OR) (95% confidence interval [CI] of 1.1 (1.0-1.1)}, body mass index [BMI] (0.86 [0.7-1.0]), and previous surgery (4.4 [1.2-16.5]). The accuracy of this prediction model did not improve when the genetic markers were added (area under the curve [AUC] from 0.80 [0.67-0.93] to 0.78 [0.65-0.91]). The predicted probabilities for PNR to IFX increased from 1% to 53% depending on the combination of final predictors. CONCLUSIONS Readily available clinical factors [age at first IFX, BMI, and previous surgery] outperform serological and IBD risk loci in prediction of primary response to infliximab in this real-life cohort of CD patients. This matrix tool could be useful for guiding physicians and may avoid unnecessary or inappropriate exposure to IFX in IBD patients unlikely to benefit.

Abstract
Lack of response to monoclonal antibodies (mAbs) has been associated with inadequate mAb serum concentrations. Therapeutic drug monitoring (TDM) of mAbs has the potential to guide to more effective dosing in individual patients. This review discusses the mechanisms responsible for interpatient variability of mAb pharmacokinetics, summarizes exposure-response data of mAbs used in inflammatory and malignant disease, presents current evidence of mAb-TDM in inflammatory disease, and provides hurdles and required future steps for further implementing mAb-TDM.

Abstract
BACKGROUND Acute severe ulcerative colitis (ASUC), the most aggressive presentation of ulcerative colitis (UC), occurs in 15% of adults and children with UC. First line therapy with intravenous corticosteroids is ineffective in half of adults and one-third of children. Therapeutic monoclonal antibodies against TNF (anti-TNF therapy) are emerging as a common treatment for ASUC due to their similar efficacy to calcineurin inhibitors and more favourable adverse effect profile. AIM To comprehensively review the evidence for anti-TNF therapy for ASUC in children and adults with regard to outcomes and pharmacokinetics. METHODS PubMed and recent conference proceedings were searched using the terms 'ulcerative colitis', 'acute severe ulcerative colitis', 'anti-TNF', 'pharmacokinetics' and the generic names of specific anti-TNF agents. RESULTS Outcomes after anti-TNF therapy for ASUC remain suboptimal with about one half of children and adults undergoing colectomy. While several randomised controlled trials have demonstrated the efficacy of anti-TNF therapy for ambulatory patients with moderate to severely active UC, patients in these studies were less ill than those with ASUC. Patients with ASUC may exhibit more rapid clearance of anti-TNF biologics due to pharmacokinetic mechanisms influenced by disease severity. CONCLUSIONS Conventional weight-based dosing effective in patients with moderately to severely active UC, may not be equally effective in those with acute severe ulcerative colitis. Personalised anti-TNF dosing strategies, which integrate patient factors and early measures of pharmacokinetics and response, hold promise for ensuring sustained drug exposure and maximising early mucosal healing in patients with acute severe ulcerative colitis.
