RESUMO

INTRODUCTION: Response to anti-TNF therapy is crucial for life expectancy and life quality in patients with severe Crohn's disease. We investigated if a previously reported gene expression profile predictive for infliximab response could be also applied to adalimumab response in an independent cohort. METHODS: Forty-seven Slovene Crohn's disease patients indicated for adalimumab therapy were enrolled in the study. Inflamed and non-inflamed colon biopsy samples were obtained during routine colonoscopy prior to adalimumab treatment. Response to adalimumab was measured with IBDQ. Gene expression in inflamed and non-inflamed colon biopsy samples was measured with RT-qPCR. Genotypes were extracted from previously available genotype data. Statistical analysis was performed with SPSS software. The R package e1071 was used to train bootstrap aggregated support vector machines (SVM). RESULTS: SVM prediction model analysis was used to analyze pooled, non-inflamed, and inflamed colon tissue datasets using IBDQ response after 4, 12, 20 and 30 weeks of adalimumab treatment. The bagging approach was used in an endeavor to obtain 100 % accuracy using 10 × 100 or 100 × 100 iterations. Average adalimumab response prediction accuracy is 75.5 % for pooled samples, 90.5 % for inflamed samples, and 100 % for non-inflamed samples. Moreover, models trained on selected SNPs from analyzed genes had an average accuracy of 92.8 %, confirming the involvement of genetic regions mapping the reported genes. Finally, using combined gene expression and SNP data we observed 100 % adalimumab response prediction accuracy for pooled, inflamed, and non-inflamed datasets. DISCUSSION: Our study supports the reported genetic anti-TNF response profile and extends it for adalimumab prediction.

RESUMO

Ulcerative colitis (UC) and Crohn disease (CD) are the most common forms of inflammatory bowel disease (IBD). Because these subtypes of IBD are characterized by periods of activity and remission, an understanding of the modulation of biochemical markers with the clinical features of IBD or its treatment, may be useful for determining the correct treatment protocol.This study aimed to evaluate the serum levels of 27 protein biomarkers to determine their association with IBD, correlation with clinical findings of disease, and modulation according to the pharmacologic therapy.A case-control study was carried out in Zacatecas, Mexico. The 27 protein profiles of serum from 53 participants (23 UC, 11 CD, and 19 controls) were evaluated using the Pro Human Cytokine 27-Plex immunoassay (Bio-Rad).Considering the controls as a reference, the group with IBD endoscopic activity showed higher serum levels of granulocyte colony-stimulating factor (G-CSF), interleukin 1 receptor antagonist (IL-1Ra), and platelet-derived growth factor BB (PDGF-BB) (P < .05). Interferon-induced protein 10 (IP-10) was associated with extraintestinal symptoms of disease (P = .041). Both PDGF-BB and interleukin 6 (IL-6) showed the strongest correlations with clinical features of IBD. Levels of IL-6, IL-7, and monocyte chemoattractant protein 1 were higher with 5-aminosalicylic acid (5-ASA) + Azathioprine therapy than controls (P < .05). Combined therapy with 5-ASA + Adalimumab led to the strongest changes in marker modulation: IL-4, IL-5, IL-15, and PDGF-BB, were upregulated (P < .05).Elevated serum levels of G-CSF, IL-1Ra, and PDGF-BB were associated with IBD endoscopic activity, and of IP-10 with extraintestinal manifestations of IBD. Combined therapy of 5-ASA + Adalimumab produced significant upregulation of IL-4, IL-5, IL-15, and PDGF-BB. This information may be useful for deciding on the course of pharmacologic therapy for patients with IBD and for generating new therapy alternatives to improve the outcome of patients with IBD.

RESUMO

We present herewith cases of non-infectious uveitis with biological treatment where the ocular complaints were the initial symptoms indicating a multi-organ autoimmune disease. The first case was a patient with panuveitis and Vogt-Koyanagi-Harada disease, the second case was also a panuveitic patient with sarcoidosis and the third case was a patient with intermediate uveitis and inflammatory bowel disease. In all cases, emerging new, biological therapy (adalimumab) was necessary to achieve permanent inactive period of uveitis and the autoimmune disease. Introducing systemic biological treatment (adalimumab) in ophthalmology is crucial in the therapy of immune-mediated, non-infectious uveitis in order to preserve visual acuity.

RESUMO

INTRODUÇÃO: A colite ulcerativa (RCU) é uma doença inflamatória intestinal (DII) crônica caracterizada por inflamação difusa da mucosa cólica e pela evolução recidivante e remitente. Os sinais e sintomas da RCU dependem da localização, significância e gravidade da doença. A incidência de colite ulcerativa é semelhante entre homens e mulheres. A idade do início da doença é entre 30 anos e 40 anos. No Brasil, estudo epidemiológico encontrou uma incidência média anual de 7,16 novos casos/100.000 habitantes/ano e uma prevalência de 28,3/100.000. O tratamento da RCU depende da gravidade e localização da doença. Os princípios gerais para tratar a colite ulcerativa ativa são considerar a atividade, distribuição (proctite, lado esquerdo, colite extensa) e padrão de doença (frequência de recaída, curso da doença, resposta a medicamentos anteriores, perfil de efeitos colaterais de medicação, manifestação intestinal). TECNOLOGIA: adalimumabe (Humira®), infliximabe (Remicade®, Bio-Manguinhos Infliximabe), golimumabe (Simponi®), vedolizumabe (Entyvio®). PERGUNTA: O adalimumabe, infliximabe, golimumabe e vedolizumabe são eficazes, seguros e custo-efetivos para tratamento da colite ulcerativa moderada a grave? EVIDÊNCIAS CIENTÍFICAS: a evidência disponível sobre eficácia e segurança comparativa entre biológicos para RCU moderada a grave é oriunda de metanálises indiretas. As evidências indiretas mostraram que, em pacientes que não fizeram uso prévio de biológicos, o infliximabe e o vedolizumabe são os mais bem classificados para induzir a remissão clínica e a cicatrização da mucosa. As evidências sugerem que o infliximabe apresenta um desempenho melhor do que o adalimumabe e o golimumabe. Todos os tratamentos avaliados (com exceção do infliximabe) não aumentaram as taxas de eventos adversos, enquanto o vedolizumabe foi estatisticamente inferior ao placebo em relação à ocorrência de eventos adversos graves. AVALIAÇÃO ECONÔMICA: Em comparação com a terapia com adalimumabe (menor custo e menor efetividade), o golimumabe apresentou uma relação de custo-efetividade incremental (RCEI) de R$ 27.849,62 por QALY ganho e o infliximabe, mostrou uma RCEI de R$ 39.358,70 por QALY, ao passo que o vedolizumabe, mostrou uma RCEI de R$ 58.624,33. O infliximabe quando comparado com golimumabe mostrou uma RCEI de R$ 44.936,40 por QALY ganho. Já o vedolizumabe quando comparado ao infliximabe resultaria em uma RCEI de R R$76.227,79 por QALY ganho. AVALIAÇÃO DE IMPACTO ORÇAMENTÁRIO: O impacto orçamentário com a inserção dos quatro biológicos para RCU moderada a grave após falha da terapia convencional, seria cerca de R$ 89,04 milhões no primeiro ano, totalizando cerca de R$ 393,5 milhões em cinco anos. Caso fosse incorporado apenas o golimumabe, o infliximabe e vedolizumabe nas proporções 20%, 40% e 40%, respectivamente, o impacto no orçamento no primeiro ano seria de R$ 96 milhões com total de R$ 425,8 milhões em cinco anos. MONITORAMENTO DO HORIZONTE TECNOLÓGICO: O horizonte tecnológico aponta que há terapias doze terapias com diferentes mecanismos de ação e com via de administração oral em desenvolvimento. CONSIDERAÇÕES: A evidência disponível sobre eficácia e segurança entre biológicos para RCU moderada a grave é oriunda de evidências indiretas que sugerem que o infliximabe e vedolizumabe apresentaram um desempenho melhor nas fases de indução e remissão. O infliximabe parece ser o biológico mais custo-efetivo comparado ao adalimumabe. A sociedade identificou uma necessidade em saúde ainda não atendida pelo PCDT para retocolite ulcerativa vigente, caracterizada pelos pacientes que não respondem, que perdem a resposta ou apresentam intolerância aos medicamentos convencionais. RECOMENDAÇÃO PRELIMINAR DA CONITEC: Os membros do Plenário reconheceram que há uma população não contemplada no PCDT de RCU vigente que poderiam se beneficiar com o uso de biológico. Os medicamentos infliximabe e vedolizumabe apresentaram como candidatos potenciais para esta lacuna, desde que atendidos os requisitos de eficácia, segurança, custoefetividade e impacto orçamentário para o SUS. Neste sentido, a Conitec, em sua 79ª reunião ordinária, recomendou que a matéria fosse disponibilizada em consulta pública com recomendação preliminar pela incorporação no SUS do vedolizumabe e infliximabe para RCU moderada a grave. CONSULTA PÚBLICA: Foram recebidas 1525 contribuições, sendo 121 técnico-científicas e 1404 contribuições de experiência ou opinião. A maioria discordou parcialmente da recomendação da Conitec sendo o principal argumento a necessidade de incorporação de todos os biológicos avaliados. As evidências apresentadas já haviam sido incluídas ou não estavam de acordo com os critérios de inclusão estabelecidos neste relatório. O tratamento da população pediátrica foi abordado, sendo o infliximabe, o único biológico com indicação em bula para esta população. A CONITEC entendeu que não houve argumentação suficiente para alterar sua recomendação inicial. RECOMENDAÇÃO FINAL: Os membros da Conitec presentes na 81ª reunião ordinária, deliberaram por recomendar a incorporação do infliximabe e do vedolizumabe para tratamento da retocolite ulcerativa moderada a grave, conforme Protocolo Clínico e Diretrizes Terapêuticas e não recomendar adalimumabe e golimumabe. Foram assinados os Registros de Deliberação nº 469/2019 e n° 473/2019. DECISÃO: Incorporar o infliximabe e o vedolizumabe para o tratamento da retocolite ulcerativa moderada a grave, limitados ao custo do tratamento com infliximabe conforme Protocolo Clínico e Diretrizes Terapêuticas do Ministério da Saúde e não incorporar o adalimumabe e o golimumabe para tratamento de retocolite ulcerativa moderada a grave, no âmbito do Sistema Único de Saúde ­ SUS. Dada pela Portaria n° 49, publicada no Diário Oficial da União n° 206, seção 1, página 45, em 23 de outubro de 2019.

RESUMO

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is widely accepted as the operation of choice for refractory ulcerative colitis (UC), UC with dysplasia or cancer, or familial adenomatous polyposis. Pouchitis is the most frequent complication after IPAA for UC. Although the pathogenesis of pouchitis remains unclear, current evidence suggests that dysbiosis and mucosal immune response are important mechanisms. Antibiotics are the first-line treatment for the condition, but some patients develop chronic refractory pouchitis. Such cases can be treated with regimens such as longer courses of antibiotic combinations, mesalazine, corticosteroids, probiotics, or biologics. But if pouch inflammation is not ameliorated, a permanent ileostomy may be required. A 40-year-old man had undergone IPAA for UC and was diagnosed with pouchitis according to the Pouchitis Disease Activity Index. Antibiotics, mesalazine, and corticosteroids were given, but the inflammation was difficult to control. He developed chronic refractory pouchitis associated with perianal abscesses and anal fistulae. Following a seton procedure for fistulae, adalimumab (ADA) was administered. After 42 weeks, the ulcers in the pouch became scarred, and the anal fistulae were closed endoscopically. After remission was induced, it has been maintained. ADA is a fully human anti-tumor necrosis factor-α (TNF-α) monoclonal antibody that has been successfully used to treat refractory Crohn disease of the ileoanal pouch. Although some studies report that infliximab, a chimeric anti-TNF-α monoclonal antibody, is efficacious in patients with refractory pouchitis, clinical evidence for the use of ADA is limited. This case illustrates achievement of induction and maintenance of remission of refractory pouchitis with ADA. It is possible that patients with this condition can avoid a permanent ileostomy with anti-TNF-α therapy. In the near future, further study of long-term clinical outcomes of anti-TNF-α therapy is expected.

RESUMO

BACKGROUND: Biologic therapies are widely used in patients with ulcerative colitis. Head-to-head trials of these therapies in patients with inflammatory bowel disease are lacking. METHODS: In a phase 3b, double-blind, double-dummy, randomized trial conducted at 245 centers in 34 countries, we compared vedolizumab with adalimumab in adults with moderately to severely active ulcerative colitis to determine whether vedolizumab was superior. Previous exposure to a tumor necrosis factor inhibitor other than adalimumab was allowed in up to 25% of patients. The patients were assigned to receive infusions of 300 mg of vedolizumab on day 1 and at weeks 2, 6, 14, 22, 30, 38, and 46 (plus injections of placebo) or subcutaneous injections of 40 mg of adalimumab, with a total dose of 160 mg at week 1, 80 mg at week 2, and 40 mg every 2 weeks thereafter until week 50 (plus infusions of placebo). Dose escalation was not permitted in either group. The primary outcome was clinical remission at week 52 (defined as a total score of ≤2 on the Mayo scale [range, 0 to 12, with higher scores indicating more severe disease] and no subscore >1 [range, 0 to 3] on any of the four Mayo scale components). To control for type I error, efficacy outcomes were analyzed with a hierarchical testing procedure, with the variables in the following order: clinical remission, endoscopic improvement (subscore of 0 to 1 on the Mayo endoscopic component), and corticosteroid-free remission at week 52. RESULTS: A total of 769 patients underwent randomization and received at least one dose of vedolizumab (383 patients) or adalimumab (386 patients). At week 52, clinical remission was observed in a higher percentage of patients in the vedolizumab group than in the adalimumab group (31.3% vs. 22.5%; difference, 8.8 percentage points; 95% confidence interval [CI], 2.5 to 15.0; P = 0.006), as was endoscopic improvement (39.7% vs. 27.7%; difference, 11.9 percentage points; 95% CI, 5.3 to 18.5; P<0.001). Corticosteroid-free clinical remission occurred in 12.6% of the patients in the vedolizumab group and in 21.8% in the adalimumab group (difference, -9.3 percentage points; 95% CI, -18.9 to 0.4). Exposure-adjusted incidence rates of infection were 23.4 and 34.6 events per 100 patient-years with vedolizumab and adalimumab, respectively, and the corresponding rates for serious infection were 1.6 and 2.2 events per 100 patient-years. CONCLUSIONS: In this trial involving patients with moderately to severely active ulcerative colitis, vedolizumab was superior to adalimumab with respect to achievement of clinical remission and endoscopic improvement, but not corticosteroid-free clinical remission.

RESUMO

Introduction: Uveitis is characterized by inflammation of the middle layer of the eye. Its overall incidence is low. Autoimmune diseases and infections are the most common underlying diseases. Out of the autoimmune diseases, juvenile idiopathic arthritis is associated most frequently with uveitis. The topical ophthalmological treatment may fail in a significant proportion of the patients and immunomodulatory therapy may be required. Aim and method: In a retrospective study, data of 33 children diagnosed and treated with uveitis at the Department of Pediatrics and Ophthalmology, University of Pécs during the last 5 years were collected and analyzed. Results: The mean age of the patients was 9.3 (0.3-17.8) years. Boys and girls were equally affected with an exception of patients with juvenile idiopathic arthritis where female predominance was found. An underlying disease could be identified in 60% of the cases (20/33). Uveitis was associated in 12 patients with juvenile idiopathic arthritis, in 2 patients with Behcet's disease and in a single case with inflammatory bowel disease. Infections have been proven in 5 patients. The autoimmune diseases caused an eye inflammation typically in anterior localization, in contrast to the infections that resulted in posterior uveitis. The majority of the patients required systemic treatment. 3 of them received systemic corticosteroid and 18 patients methotrexate as disease-modifying antirheumatic drug. 13 children with severe disease activity required biological therapy (adalimumab injection). Remission could be achieved in 1.45 (0.75-2.5) months. Conclusion: Pediatric uveitis is of great importance. Early diagnosis, adequate therapy and follow-up require multidisciplinary cooperation.

RESUMO

Introduction: Medical treatment of pediatric inflammatory bowel diseases (IBD) has been greatly changed by the introduction of a number of biologic agents that are able to target various players of the immune response. In particular, monoclonal antibodies against the pro-inflammatory cytokine TNF-alpha (TNF) such as infliximab, adalimumab, and golimumab are now in the clinics both in induction and maintenance therapy, and several efforts are currently ongoing to optimize the use of these drugs in children. Areas covered: This review focuses on therapeutic drug monitoring (TDM) of anti-TNF levels and antidrug antibodies (ADAs), in IBD children. A revision of the analytical assays used for assessing anti-TNF plasma levels is also provided. Expert opinion: Although there is a consensus across studies that higher anti-TNF trough levels are associated with a better clinical outcome, and that early anti-TNF serum measurements could be predictive of long-term response, it is still not clear what the best predictive time of sampling is and what the ideal target drug plasma concentration to achieve. Indeed, there are a number of published studies, particularly in pediatric cohorts, limited by the population size analyzed and more prospective large studies are needed to examine the value of these predictive markers.

RESUMO

BACKGROUND & AIMS: Proactive monitoring of drug trough concentrations and antibodies against drugs might help determine whether patients are likely to respond to treatment and increase efficacy. We investigated whether proactive drug monitoring is associated with higher rates of clinical remission in pediatric patients with Crohn's disease (CD). METHODS: We performed a nonblinded, randomized controlled trial of 78 children with CD (6-18 years old; 29% female; mean age, 14.3 ± 2.6 years) who had not received prior treatment with a biologic agent but had responded to adalimumab induction therapy, under scheduled monitoring of clinical and biologic measures (based on clinical factors and levels of C-reactive protein and fecal calprotectin), at pediatric gastroenterology units in Israel from July 2015 through December 2018. The patients were randomly assigned to groups that received proactive monitoring (trough concentrations measured at weeks 4 and 8 and then every 8 weeks until week 72, n = 38) or reactive monitoring (physicians were informed of trough concentrations after loss of response, n = 40). In both groups, doses and intervals of adalimumab were adjusted to achieve trough concentrations of 5 µg/mL. The primary endpoint was sustained corticosteroid-free clinical remission at all visits (week 8 through week 72). RESULTS: The primary endpoint was achieved by 31 children (82%) in the proactive group and 19 children (48%) in the reactive group (P = .002). Sixteen patients in the proactive monitoring group (42%) achieved a composite outcome of sustained corticosteroid-free remission, C-reactive protein ≤0.5 mg/dL, and level of fecal calprotectin ≤150 µg/g compared with 5 patients in the reactive monitoring group (12%) (P = .003). By week 72 of treatment, 33 patients in the proactive monitoring group had received adalimumab intensification (87%) compared with 24 patients in the reactive monitoring group (60%) (P = .001). CONCLUSIONS: In a randomized controlled trial of pediatric patients with CD, we found that proactive monitoring of adalimumab trough concentrations and adjustment of doses and intervals resulted in significantly higher rates corticosteroid-free clinical remission than reactive monitoring (measuring trough concentration after loss of response).

RESUMO

The article provides clinical observation of a patient who was diagnosed with celiac disease when he was 52 years (Marsh stage IIIB). Following gluten-free diet (GFD) clinical remission and restoration of small intestinal mucosa (SIM) structure occurred, however in 6 years ulcerative colitis developed and an impairment of SIM morphological structure was identified (Marsh stage IIIA). Ulcerative colitis and celiac disease remission is supported by GFD, anti-cytokine therapy (adalimumab) in combination with mesalazine.

RESUMO

In the present single-center retrospective study, we investigated our data to evaluate the efficacy of the classic antibiotic combination (rifampicin and clindamycin) compared to adalimumab treatment in patients affected by moderate-to-severe hidradenitis suppurativa. Disease severity and quality of life were registered using the modified Sartorious score and Hidradisk, respectively. Data were collected before starting treatment (T0) and after ten weeks of therapy (T10). The Mann-Whitney test was used to calculate statistical differences between baseline and week 10. P values less than 0.05 were considered to be statistically significant. A spearman test was used to evaluate the correlation among the parameters under study. Thirty patients (20 females, 10 males; mean age, 23.73 ± 4.57) were given the antibiotics: instead of starting the treatment by combining the two antibiotics, we recommend patients to start the therapy taking only rifampicin 300 mg twice a day for 7 days, and after the first week, to add clindamycin at a dose of 300 mg twice a day. The mean modified Sartorius Score before starting treatment was 68.8 while the value at week 10 was 57.8 (P equals 0.0052). The mean Hidradisk value before starting treatment was 74,73 while the value at week 10 was 62 (P equals 0.0095). Ten patients (10/30) achieved the HiSCR. On the other hand, thirty subjects (22 females, 8 males; mean age, 26.2±7.25) were treated with subcutaneous injections of adalimumab (160 mg at baseline, 80 mg at week 2, 40 mg at week 4, and 40 mg weekly thereafter). The mean modified Sartorius Score before starting treatment was 74.93 while the value at week 10 was 39.86 (P less than 0.0001). The mean Hidradisk value before starting treatment was 77.73 while the value at week 10 decreased to 51.86 (P less than 0.0001). Eighteen patients (18/30) achieved the HiSCR.

RESUMO

The use of therapeutic monoclonal antibodies (mAbs) is steadily increasing. Previous studies have reported the clinical interest of mAb therapeutic-drug monitoring (TDM), including that of adalimumab, for patients with Crohn's disease (CD). Proof of concept mAb-quantification studies by liquid chromatography mass spectrometry (LC-MS/MS) have been published, but a specific and reliable routine-suited multiplex quantification method is still needed to facilitate mAb TDM. We describe an electrospray ionization LC-MS/MS method for the simultaneous quantification of seven mAbs (adalimumab, cetuximab, infliximab, rituximab, secukinumab, tocilizumab, and trastuzumab) in human plasma. Sample preparation was performed using protein-G purification and trypsin digestion to obtain proteotypic peptides. We retrospectively measured the adalimumab concentration in 65 plasma samples from 56 CD patients and determined the adalimumab therapeutic cut-off concentration associated with biological remission. Calibration curves were linear from 1 to 100 µg mL-1, except for rituximab (5-100 µg mL-1). This method was reproducible, repeatable, and accurate (coefficient of variation and bias < 20%), with no cross contamination. Adalimumab concentrations were significantly higher (p = 0.0198) for patients with biological remission (median: 11.3 µg mL-1 [4.6; 18.3]) than that for patients without a biological response (9.5 µg mL-1 [3.94;17.0]). An adalimumab cut-off concentration of 8.0 µg mL-1 correctly discriminated patients with or without biological remission (sensitivity: 74.1%, specificity: 57.9%). This validated LC-MS/MS routine-suited method is the first allowing simultaneous quantification of up to seven mAbs acting against different pharmacological targets. It opens the field of TDM to numerous mAbs.

RESUMO

Inflammatory bowel disease (IBD) presents with disabling symptoms and may lead to insufficient growth and late pubertal development in cases of disease onset during childhood or adolescence. During the last decade, the role of anti-tumor necrosis factor (TNF) in the treatment of paediatric-onset IBD has gained more ground. The number of biologicals presently available for children and adolescents with IBD has increased, biosimilars have become available, and practices in adult gastroenterology with regards to anti-TNF have changed. The aim of this study is to review the current evidence on the indications, judicious use, effectiveness and safety of anti-TNF agents in paediatric IBD. A PubMed literature search was performed and included articles published after 2000 using the following terms: child or paediatric, Crohn, ulcerative colitis, inflammatory bowel disease, anti-TNF, TNF alpha inhibitor, infliximab, adalimumab, golimumab and biological. Anti-TNF agents, specifically infliximab and adalimumab, have proven to be effective in moderate and severe paediatric IBD. Therapeutic drug monitoring increases therapy effectiveness and safety. Clinical predictors for anti-TNF response are currently of limited value because of the variation in outcome definitions and follow-ups. Future research should comprise large cohorts and clinical trials comparing groups according to their risk profile in order to provide personalized therapeutic strategies.

RESUMO

INTRODUÇÃO: A doença de Crohn é uma doença crônica e sem cura, que se apresenta ao longo da vida como crises agudas (com diarreia, dor abdominal, febre, perda de peso e sangramento retal) e períodos de remissão (ausência de sintomas). O tratamento no SUS é feito com corticosteroides, imunossupressores (azatioprina e metotrexato) e anti-TNF (infliximabe, adalimumabe e certolizumabe pegol). TECNOLOGIA: Vedolizumabe (Entyvio®). PERGUNTA: Em pacientes adultos com DC moderada a grave que apresentaram resposta inadequada, perda de resposta ou intolerância ao tratamento convencional (corticosteroides e imunossupressores) ou a um anti-TNF, o uso de vedolizumabe (Entyvio®) proporciona maior indução e manutenção de remissão, com cicatrização da mucosa, e menor frequência de óbitos, eventos adversos graves e infecções graves, quando comparado aos anti-TNF disponíveis no SUS (infliximabe, adalimumabe e certolizumabe pegol)? EVIDÊNCIAS CIENTÍFICAS: Não foram localizados estudos de comparação direta entre vedolizumabe e anti-TNF que avaliassem os desfechos de interesse. A eficácia e segurança do vedolizumabe em pacientes com DC é proveniente de ensaios clínicos randomizados de comparação com placebo, GEMINI 2 e GEMINI 3 (evidência com qualidade moderada por se tratar de evidência indireta) e meta-análise indireta. Vedolizumabe apresenta superioridade comparado ao placebo no desfecho de indução de remissão em 6 e 10 semanas (RR 1,77 IC 95% 1,21 a 2,59 e RR 2,2 IC 95% 1,4 a 3,3, respectivamente). A manutenção da remissão também foi maior em pacientes que receberam vedolizumabe a cada 8 semanas, por 52 semanas, comparado a placebo (RR 1,8 IC 95% 1,2 a 2,6). Não foram identificados estudos comparativos para o desfecho de cicatrização da mucosa. O perfil de segurança do vedolizumabe (óbitos, eventos adversos graves e infecções graves) não apresentou diferença estatística quando comparado ao placebo ou, de forma indireta, aos anti-TNF. AVALIAÇÃO ECONÔMICA: A empresa fabricante do vedolizumabe apresentou uma análise de custominimização assumindo que os biológicos têm eficácia semelhante. A incorporação do vedolizumabe ao SUS, considerando o custo do fármaco proposto pela empresa e com desoneração de impostos, equivaleria ao custo do tratamento com infliximabe, mas resultaria em um incremento no primeiro ano de tratamento de R$ R$12.301,34 e R$ 13.508,88 em comparação com adalimumabe e certolizumabe pegol, respectivamente. No entanto, se considerarmos o valor do medicamento com carga tributária total (R$4.754,11), o custo no primeiro ano de tratamento seria de R$38.033, muito acima dos custos de tratamento com os biológicos disponíveis no SUS. O custo incremental comparado com o infliximabe, neste caso, seria de R$10.934,00. AVALIAÇÃO DE IMPACTO ORÇAMENTÁRIO: O impacto orçamentário não apresentou custos adicionais com o preço proposto do vedolizumabe sem impostos e com uma baixa emigração de infliximabe para vedolizumabe. Entretanto, se considerarmos o custo do vedolizumabe com impostos, o impacto orçamentário incremental seria superior a R$ 122 milhões em cinco anos. Este valor seria ainda maior caso fossem consideradas as falhas terapêuticas dos anti-TNF e migração para vedolizumabe a partir do adalimumabe e certolizumabe pegol. MONITORAMENTO DO HORIZONTE TECNOLÓGICO: Foram identificadas seis tecnologias com registro potencial para a mesma indicação, incluindo mecanismos de ação diferentes e formulação oral. CONSIDERAÇÕES: Em consulta prévia à associação de pacientes com DC e à sociedade médica relacionada, foram identificadas necessidades em saúde ainda não atendidas pelo atual PCDT da DC, caracterizada pelos pacientes que não respondem, que perdem a resposta ou apresentam intolerância aos medicamentos anti-TNF. RECOMENDAÇÃO PRELIMINAR: O Plenário da CONITEC, em 14/03/2019, considerou que o PCDT atual da DC já preconiza linhas de tratamento biológico para pacientes falhados a corticosteroides e imunossupressores. Para os pacientes falhados aos anti-TNF, o vedolizumabe não demonstra superioridade, e, portanto, considerou-se que o custo da dose não poderia ser superior a R$ 1.850, e não R$ 3.387 proposto pela empresa. Assim, emitiu-se recomendação preliminar pela não incorporação no SUS do vedolizumabe (Entyvio®) para Doença de Crohn. CONSULTA PÚBLICA: Foram recebidas 86 contribuições técnico-científicas e 256 contribuições de experiência ou opinião, a maioria discordante com a recomendação preliminar da CONITEC. Foram apresentados estudos publicados e opiniões sobre a ausência de opções pós anti-TNF e para pacientes com risco aumentado de infecções e com contraindicação aos anti-TNF. A empresa demandante apresentou nova proposta de preço, de R$ 3.218 por frasco-ampola, e custo no primeiro de tratamento de R$ 25.744. A CONITEC entendeu que não houve argumentação suficiente para alterar sua recomendação inicial. RECOMENDAÇÃO FINAL: Os membros da CONITEC em 08/05/2019 deliberaram por recomendar a não incorporação no SUS do vedolizumabe (Entyvio®) para Doença de Crohn moderada a grave. Foi assinado o Registro de Deliberação nº 439/2019. CONFLITOS DE INTERESSES: os elaboradores deste relatório declaram não possuir conflitos de interesses com a matéria em análise. DECISÃO: Não incorporar o vedolizumabe para o tratamento de pacientes adultos com doença de Crohn moderada a grave, no âmbito do Sistema Único de Saúde ­ SUS. Dada pela Portaria n° 26, publicada no Diário Oficial da União n° 100, seção 1, página 45, em 27 de maio de 2019.

RESUMO

Adalimumab, the first fully humanised monoclonal antibody against tumour necrosis factor alpha (TNF-α), has played a leading role in the revolution brought about by the introduction of biologics, and has received the widest range of indications among TNF-α inhibitors. Post-registration, observational and registry studies of real-life use have largely supported the outcomes seen in registrational clinical trials. With the recent loss of exclusivity for the originator medicinal product in Europe, a number of biosimilar adalimumab molecules have been licensed for use in the same indications as the originator molecule across rheumatology, dermatology, gastroenterology and ophthalmology. Clinicians in these areas first gained experience with biosimilar infliximab, followed by etanercept and rituximab. However, adalimumab is likely to present unique challenges given the numbers of patients treated and the range of biosimilar adalimumab products available. The biosimilar approval pathway has an emphasis on the pre-clinical analytic data in combination with clinical studies conducted to confirm therapeutic equivalence. To date, several adalimumab biosimilars have entered the EU market following successful marketing authorisation applications and recent expiration of originator patent protection. This overview covers the extent of use of adalimumab and summarises the regulatory process involved in the development of biosimilars as well as their use in clinical practice. The authors also discuss clinical data available so far on adalimumab biosimilars and their envisaged impact in the field of immune-mediated inflammatory diseases.

RESUMO

BACKGROUND: The optimal treatment of serpiginous choroiditis is not established. While recent reports indicate the efficacy of adalimumab, there is limited evidence. We present a case of serpiginous choroiditis refractory to steroids, immunosuppressants, and adalimumab. CASE PRESENTATION: An 18-year-old woman presented with severe vision loss in both eyes. A fundus examination revealed a foveal grayish-white lesion, and optical coherence tomography revealed outer retinal damage. She was diagnosed with serpiginous choroiditis and treated with steroid pulse therapy, but the disease progressed continuously. The addition of sub-Tenon's injection of triamcinolone and oral cyclosporine did not change the disease course. We also administered subcutaneous injections of adalimumab, but even with the intensive treatment, the retinal lesions and subsequent atrophy progressed. Her right and left visual acuity declined from 20/22 to 20/66 and 20/200, respectively, during the 9 months of follow-up. CONCLUSION: Here, we report a case of serpiginous choroiditis refractory to corticosteroids, immunosuppressants, and adalimumab. Further studies are needed to establish the optimal treatment for such cases.
