Abstract

Objectives: To analyze the efficacy and safety of the new direct antiviral agents (DAA) that will become the new therapeutic arsenal for the treatment of hepatitis C.

Methods: We carried out a research in the electronic database with the following criteria: phase II and III clinical trials (CT) published until February 2014. The Mesh term used was "chronic hepatitis C" and "therapy".Studies with boceprevir or telaprevir were excluded. For the analysis of efficacy, we evaluated the rate of Sustained Viral Response(SVR), and for the safety, side effects and safety-related discontinuations were analyzed.

Results: We included 24 CT that include associations with ribavirine(RBV) with or without peginterferon (PegINF) and associations of several DAA. The results associated of daclatasvir with PegINF and RBV have not been very successful. On the contrary, sofosbuvir presents activity in all viral genotypes . Sofosbuvir may be administered in free PegINF regimens. Around 90% of naïve patients achieve sustained virological response (RVS) and 80% in previously treated. In relation to second wave of NS3/4A protease inhibitors, simeprevir has achieved RVS in 90% of naïve patients and close to 80% in previously treated.The main combination of DAA were sofosbuvir and daclatasvir and sofosbuvir and ledipasvir. Both have achieved SVR in 100% of patients who previously had virological failure after receiving a protease inhibitor regimen with boceprevir or telaprevir.

Conclusions: The new generation of AAD for the treatment of hepatitis C will lead to higher response rates in all subtypes of patients with lower complexity regimens and better tolerated.

Objetivos: Analizar la eficacia y seguridad de los nuevos agentesantivirales directos (AAD) que formaran parte del arsenal terapéuticopara el tratamiento de la hepatitis C.Método: Se realizó una búsqueda en la base de datos electrónicaPubMed, de artículos publicados Febrero de 2014 quecumplieran los siguientes criterios: ensayos clínicos (EC) en faseII o III y cuyos objetivos fueran evaluar la eficacia y seguridad denuevas generaciones de inhibidores de la proteasa (IP) frente alVHC, excluyendo con boceprevir y telaprevir.Resultados: Se incluyeron de 24 EC que incluyen asociacionesde AAD con ribavirina (RBV) y con o sin peginterferon (PegINF)y asociaciones de varios AAD. Los resultados de daclatasvircon PegINF y RBV no han sido muy satisfactorios. Por el contrario,sofosbuvir es activo en todos los genotipos virales y permiteser administrado en regímenes libres de PegINF. Alrededordel 90% de los pacientes naïve alcanzan respuesta viralsostenida (RVS) , y no llegan al 80% en pretratados. En cuantoa la segunda generación de IP NS3/4A, destacar a simeprevir,con respuestas próximas al 90% en pacientes naïve y cercanasal 80% en pretratados. Entre las combinaciones de AAD evaluadas,sofosbuvir y daclatasvir y sofosbuvir y ledipasvir alcanzanel 100% de respuesta en no respondedores a triple terapiacon boceprevir y telaprevir.Conclusiones: Las nuevas generaciones de AAD frente al VHCvan a suponer un aumento de las tasas de curación en todoslos subtipos de pacientes, a través de regímenes más sencillosy mejor tolerados.
