Abstract

Fundamento:Tocilizumab (TCZ) fue superior a adalimumab (ADA) enmonoterapia en la reducción de los signos y síntomas de la artritis reumatoide del adulto (AR) en pacientes intolerantes o con respuesta inadecuada a metotrexato (MTX) . El objetivo del estudio fue analizar el coste-Efectividad de TCZ vs ADA en estos pacientes. Métodos: Evaluación económica del coste por respuesta o remisión con TCZ vs ADA a partir del estudio ADACTA (horizonte temporal: 24 semanas). Criterios de respuesta clínica ACR o de remisión de la enfermedad, índice DAS28. Ámbito: Sistema Nacional de Salud. Los costes incluidos (adquisición, administración y monitorización de los medicamentos en € de 2012) se obtuvieron de fuentes españolas. Se efectuaron análisis de sensibilidad simples univariantes. Resultados: Las tasas de respuesta ACR20, ACR50 y ACR70 con TCZyADA se obtuvieron en el 65% y 49, 4% (p<0,01); 47,2% y 27,8% (p<0,01); y en el 32,5% y 17,9% (p<0,01) de los pacientes, respectivamente. La remisión DAS28 se produjo en el 39,9% y 10,5%, respectivamente (p<0,0001). El coste por respuesta fue menor con TCZ que con ADA (ACR20: 8.105 y 11.553 €;ACR50:11.162 y 20.529 €; ACR70: 16.211 y 31.882 €) respectivamente. El coste de la remisión DAS28 fue de 13.204 € y 54.352 € respectivamente. En todos los escenarios el tratamiento con TCZ tuvo mayor eficacia y menores costes que con ADA. Conclusiones: Según este análisis, en España la monoterapia con TCZ es una estrategia eficiente frente a ADA para el tratamiento de los pacientes con AR intolerantes o con respuesta inadecuada a MTX.
BACKGROUND Tocilizumab (TCZ) was superior to adalimumab (ADA), as monotherapy, in reducing signs and symptoms of adult rheumatoid arthritis (RA) when methotrexate (MTX) treatment is poorly tolerated or inappropriate. The aim of the study was to analyze the cost-effectiveness of TCZ vs ADA in these patients. METHODS Economic evaluation of the cost per response or remission of TCZ vs ADA from ADACTA (time horizon: 24 weeks). Clinical response criteria ACR or disease remission criteria, DAS28. PERSPECTIVE National Health System. The costs included (acquisition, administration and monitoring of medicines; € 2012) were obtained from Spanish sources. Simple univariate sensitivity analyzes were performed. RESULTS ACR20, ACR50 and ACR70 response rates with TCZ and ADA were obtained in 65% and 49.4% (p <0.01), 47.2% and 27.8% (p <0.01); and 32.5% and 17.9% (p <0.01) of patients, respectively. DAS28 remission occurred in 39.9% and 10.5%, respectively (p <0.0001). The cost per response was lower with TCZ than with ADA (ACR20: € 8,105 and € 11,553; ACR50: € 11,162 and € 20,529; ACR70: € 16,211 and € 31,882) respectively. The cost of DAS28 remission was € 13,204 and € 54,352, respectively. Treatment with TCZ was dominant (more effective, with lower costs vs ADA) in all scenarios analyzed. CONCLUSIONS According to this analysis, in Spain TCZ monotherapy is an efficient strategy vs ADA for treating RA patients intolerant to MTX or in which there is inappropriate response.
