Quantitation of certolizumab pegol by validated liquid chromatography methods

Abstract Certolizumab pegol (CZP) is a Fab' fragment of the humanized antibody with anti-TNF-α activity that is indicated as therapy for Crohn's disease and rheumatoid arthritis. Using a BioSep-SEC-S3000 column (300 x 4.6 mm i.d., 5 µm particle size), a size exclusion liquid chromatography (SEC) method was developed. Mobile phase A consisted of 100 mM monobasic sodium phosphate and 200 mM sodium chloride (pH 7.0), while mobile phase B was ethanol (95:5, v/v), and the analysis was performed using a diode array detector (DAD) set to 214 nm and a flow rate of 0.5 ml min-1. In addition, a reversed-phase liquid chromatography (RP-LC) method based on gradient elution was developed on a Zorbax 300 SB C18 column (150 mm x 4.6 mm i.d., 3.5 µm particle size) kept at 80 °C. Mobile phase A was 0.1% (v/v) TFA in ultrapure water, and mobile phase B was a mixture of propanol, acetonitrile, ultrapure water and TFA (70 + 20 + 9.9 + 0.1, v/v) operated at a flow rate of 1.0 ml min-1, and DAD was applied at 214 nm. CZP elution was achieved with retention times of 5.6 min and 9.0 min for SEC and RP-LC, respectively.

Ameliorative effect of certolizumab on experimentally induced acute necrotic pancreatitis in rats

SUMMARY OBJECTIVE: The effects of Certolizumab, a pegylated monoclonal antibody to tumor necrosis factor α, on experimentally induced acute pancreatitis (AP) were examined. METHODS: Thirty-six Wistar Albino male rats were randomly divided into four groups. Group I was the control group and no medication administered to this group. Group II was the Certolizumab group, and 100 ml/kg serum physiologic administered into the biliopancreatic duct and a single dose of 10 μg Certolizumab was simultaneously administered intraperitoneally. Acute pancreatitis was induced with a retrograde injection of 3% Na taurocholate into the common biliopancreatic duct in the study (Group III) and treatment (Groups IV) groups. Rats were sacrificed 72 hours later. Serum amylase, lipase, lactate dehydrogenase activities, along with pancreatic histopathology, were examined. RESULTS: Certolizumab treatment significantly decreased serum amylase, lipase, and LDH levels; histopathologically edema, hemorrhage, parenchymal necrosis, fat necrosis, and infiltration scores; immunohistochemically MDA, MPO, TNF-α and Caspase-3 activity. CONCLUSION: The results support the idea that certolizumab might be beneficial for the severity of AP.

RESUMO OBJETIVO: Os efeitos de Certolizumab, um anticorpo monoclonal pegilado para o fator de necrose tumoral α, na pancreatite aguda induzida experimentalmente (PA) foram examinados. MÉTODO: Trinta e seis ratos Wistar Albino foram divididos aleatoriamente em quatro grupos. O Grupo I foi considerado o grupo controle e não recebeu medicação; o Grupo II foi o grupo Certolizumab e recebeu 100 ml/kg de soro fisiológico administrado no ducto biliopancreático e dose única de 10 mg Certolizumab administrada por via intraperitoneal simultaneamente. A pancreatite aguda foi induzida com uma injeção retrógrada de uma solução de 3% taurocolato de sódio aplicada no ducto biliopancreático comum nos grupos de estudo (Grupo III) e tratamento (Grupos IV). Os ratos foram sacrificados 72 horas depois. As atividades séricas de amilase, lipase, lactato desidrogenase, juntamente com a histopatologia pancreática, foram examinadas. RESULTADOS: O tratamento com Certolizumab diminuiu significativamente os níveis séricos de amilase, lipase e LDH; edema histopatológico, hemorragia, necrose paranquimatosa, necrose gordurosa e escores de infiltração; atividade imuno-histoquímica de MDA, MPO, TNF-α e Caspase-3. CONCLUSÃO: Estes resultados suportam a ideia de que o Certolizumab pode ser benéfico para a gravidade da PA.

Spotlight on certolizumab pegol in the treatment of axial spondyloarthritis: efficacy, safety and place in therapy.

Certolizumab pegol (CZP) is a pegylated humanized tumor necrosis factor-α inhibitor (TNFi) approved for the treatment of ankylosing spondylitis (AS) in the USA and for AS and non-radiographic axial spondyloarthritis (nr-axSpA) in Europe and in some Latin American countries. CZP lacks Fc region, preventing complement fixation and cytotoxicity mediated by antibody; CZP does not actively cross the placenta, unlike other TNFi. RAPID-axSpA study is a Phase III trial conducted in patients with AS and nr-axSpA as double blind and placebo controlled to week 24, dose blind to week 48 and open label to week 204. Of a total of 325 patients recruited, 107 patients were assigned to placebo and 218 patients to CZP (111 to CZP 200 mg Q2W, 107 to CZP 400 mg Q4W). Improvements in axial involvement, joint involvement, enthesitis and quality of life were reported in patients treated with CZP. Safety profile was like that reported for other TNFi in axSpA patients. In this article, we summarized the pharmacology and we reviewed the efficacy and tolerability of this drug for the treatment of axSpA. Some special considerations of CZP during pregnancy are included. CZP, the latest TNFi to be approved, showed efficacy in all manifestations of AS and nr-axSpA.

Cost-minimization and budget impact analysis of certolizumab pegol for patients with Crohn's disease, moderate or severe, with relapse after conventional treatment from the perspective of the Brazilian private payer / Análises de custo-minimização e impacto orçamentário do certolizumabe pegol para pacientes com doença de Crohn moderada a grave com falha ao tratamento convencional, sob a perspectiva do pagador privado no Brasil

Objectives: Budget impact and cost-effectiveness analysis are often required by payers when discussing drug reimbursement. We hereby present a cost-minimization (CMA) and budget impact analysis (BIA) regarding the incorporation of certolizumab pegol (CZP) for the treatment of patients with Crohn's disease, a debilitating condition that affects the digestive tract. Methods: Considering that the scientific literature demonstrates CZP as effective as the alternatives (infliximab and adalimumab), a CMA was conducted, including a Markov 10-year time horizon modeling. Focusing on the assumptions for both CMA and BIA, a total of 36 stakeholders from the private sector were surveyed regarding treatment and disease-related costs. For the BIA, drug acquisition costs, administration costs, no population growth and an immunobiologic drug (bDMARD) switching rate of 5% were also considered. We assumed that CZP would gradually gain market share until it reaches 20% of new or switching patients in the fourth year. In addition, probability sensitivity analyses were performed. Results: In the cost-minimization, the calculated costs for 10-year treatment were BRL149k (infliximab); BRL118k (adalimumab) and BRL83k (CZP). Probabilistic sensitivity analysis was conducted with 1,000 random simulations, with CZP being less costly than its comparators in all simulations. Additionally, the BIA result indicates that CZP is a cost-saving intervention, with a predicted five-year impact of BRL317k for every 100-patient cohort. Conclusions: Certolizumab pegol was shown to be not only effective but also a cost-saving drug when compared to other anti-TNF drugs available for the Brazilian private healthcare system.

Objetivos: Análises de impacto orçamentário e de custo-efetividade são, com frequência, exigidas por pagadores para a decisão sobre incorporação de drogas. Por esse motivo, apresentaremos uma análise de custo-minimização e de impacto orçamentário do certolizumabe pegol (CZP) para o tratamento de pacientes com doença de Crohn, doença crônica e debilitante que afeta o trato digestivo. Métodos: Trinta e seis pagadores privados foram entrevistados para que fosse possível compreender os custos de tratamento e aqueles relacionados à doença. Para a análise de impacto orçamentário, foram assumidos: custos de aquisição e administração das drogas, nenhuma taxa de crescimento populacional, taxa de troca de medicamento biológico (bDMARD) de 5% e market share de 20% para o CZP em seu pico. Visto que o CZP é tão eficaz e seguro quanto os comparadores disponíveis, optou-se pela análise de custo-minimização, assumindo horizonte temporal de 10 anos. Resultados: A análise de impacto orçamentário mostra que o CZP é capaz de gerar redução de custos no valor de R$ 317 mil em cinco anos, para cada cem pacientes. Para a custo-minimização, os custos calculados no horizonte de dez anos foram: R$ 149 mil para o infliximabe; R$ 118 mil para o adalimumabe e R$ 83 mil para o CZP. A análise de sensibilidade probabilística mostrou CZP menos custoso em 100% das 1.000 simulações. Conclusões: Certolizumabe pegol mostrou-se não apenas efetivo, mas também uma opção que pode gerar redução de custos quando comparada às outras drogas biológicas no Brasil sob a perspectiva do pagador privado.

An evidence-based review of certolizumab pegol in the treatment of active psoriatic arthritis: place in therapy.

Certolizumab pegol (CZP) is a pegylated humanized tumor necrosis factor-α inhibitor (TNFi) approved for the treatment of psoriatic arthritis (PsA) in Europe, the USA, and Latin American countries. CZP neutralizes TNF-α at its soluble and membrane portions. Due to the lack of Fc region, it does not induce complement or antibody-dependent cytotoxicity in vitro, unlike other TNFi. RAPID-PsA study, the only randomized clinical trial performed in PsA, is a Phase III clinical trial conducted in 409 PsA patients during 24 weeks. Patients were randomized to CZP (200 mg every 2 weeks or 400 mg every 4 weeks) or placebo. Patients in CZP arms reported improvements in skin disease, joint involvement, dactylitis, enthesitis, and quality of life. Safety profile was similar to that reported for other TNF-α inhibitors in PsA patients. This article summarizes the pharmacology and reviews the efficacy and tolerability of this drug in PsA. CZP is the newest TNFi with proved efficacy in all manifestations of psoriasis disease, except for axial involvement where the evidence has been derived from response to axial spondyloarthritis.

Tratamiento exitoso con certolizumab pegol en un paciente con enfermedad de Crohn fistulizante compleja / Severe fistulizing crohn’s disease successfully treated with certolizumab pegol

Crohn’s disease (CD) is a type of inflammatory bowel disease that may involve every segment of the entire gastrointestinal tract and is characterized by transmural inflammation and formation of granulomas. Its classic presentation is evidenced by fever, abdominal pain and signs of intestinal obstruction, however these signs could vary among patients. Fistulizing CD (FCD) is a less frequent presentation. The clinical signs and symptoms of this form are not characteristic and usually have a more complicated outcome due to the development of sepsis. Certolizumab pegol is a recombinant humanized antibody, targeting the tumor necrosis factor alpha (TNF-alpha), which has been effective in patients with fistulizing CD. In this article, we report a patient with complicated FCD who required 21 month hospitalization due to the presence of multiple fistulae and malnutrition, but who had a successful management with certolizumab pegol.

La enfermedad de Crohn (EC) es un tipo de enfermedad intestinal inflamatoria, que puede comprometer cualquier segmento del tracto gastrointestinal caracterizado por inflamación transmural y formación de granulomas. Su presentación clínica clásica se caracteriza por fiebre, dolor abdominal y signos de obstrucción intestinal, aunque estos signos pueden variar entre cada paciente. La EC fistulizante (ECF) es un tipo de presentación menos frecuente. Los síntomas y signos clínicos no son fácilmente definidos y usualmente se asocian con el desarrollo de sepsis. El certolizumab pegol es un anticuerpo monoclonal recombinante contra el factor de necrosis tumoral alfa. En este artículo se describe la evolución clínica de un paciente con ECF con múltiples complicaciones y quien requirió una hospitalización prolongada durante 21 meses debido a la presencia de múltiples fístulas y desnutrición, quien respondió satisfactoriamente al tratamiento con certolizumab pegol.

Prefilled certolizumab pegol (Cimzia(®)) syringes for self-use in the treatment of rheumatoid arthritis.

A new anti-tumor necrosis factor alpha (TNF-α) inhibitor with a novel mechanism of action has entered phase 3 trials in rheumatoid arthritis (RA). Certolizumab pegol (Cimzia(®)) is a humanized Fab' antibody fragment against TNF-α with a polyethylene glycol tail that prevents complement-dependent and antibody-dependent cell-mediated cytotoxicity or apoptosis. Four randomized clinical trials have been published so far. Reported results are similar to those published in previous studies with other TNF-α inhibitors, with ACR20, ACR50, and ACR70 responses of around 60%, 40%, and 20%, respectively, when combined with methotrexate and slightly lower when used as monotherapy. Safety was shown to be similar to that seen with TNF-α blockers and some cases of tuberculosis were seen in the trials, stressing the importance of a complete screening in these patients. Although we still need effectiveness and safety data in larger numbers of patients and longer follow-up, this new TNF inhibitor is a welcome addition to our current armamentarium for the treatment of RA.
