LONDRES, March 14, 2016 /PRNewswire/ --

Sylentis, empresa farmacéutica del Grupo PharmaMar (MSE:PHM), pionera en la investigación y desarrollo de nuevos fármacos basados en la tecnología del silenciamiento génico mediante ARN de interferencia (RNAi), presenta los resultados de dos estudios clínicos (SYL1001_II y SYL1001_III) con el medicamento en investigación SYL1001 para la búsqueda de dosis y evaluación de la eficacia para el tratamiento del dolor ocular asociado al Síndrome de Ojo Seco.

     (Logo: http://photos.prnewswire.com/prnh/20160314/343630LOGO )

Estos ensayos en fase 2, multicéntricos, aleatorizados, de grupos paralelos, controlados con placebo y doble enmascarados, se llevaron a cabo en 8 centros ubicados en 2 países europeos, España y Estonia. Los estudios incluyeron 127 pacientes con dolor ocular asociado al Síndrome de ojo seco y evaluaron la eficacia y seguridad de cuatro dosis de SYL1001 (0,375%, 0,75%, 1,125% y 2,25%) frente a placebo, tras 10 días de administración en forma de gotas oftálmicas aplicadas una vez al día.

Los resultados obtenidos indicaron que la dosis de 1,125% alcanzó mayor grado de cumplimiento de los objetivos primarios y secundarios, disminuyendo no solo el dolor ocular, sino también la hiperemia conjuntival asociada al Síndrome de ojo seco tras diez días de tratamiento.

Además, estos dos estudios también evaluaron la seguridad y tolerancia de SYL1001, confirmándose el buen perfil de seguridad y tolerancia obtenido en Fase 1, no habiendo diferencias en el porcentaje de acontecimientos adversos entre las dosis evaluadas del SYL1001 y el grupo placebo.

"Estos resultados positivos apoyan la continuidad del desarrollo clínico del SYL1001. Actualmente, Sylentis está diseñando el programa de fase 3 que validará con las autoridades competentes" explicó la doctora Ana Isabel Jiménez, Directora de Operaciones Ejecutivas de Sylentis.

Los resultados y análisis adicionales de estos ensayos clínicos serán presentados en el congreso ARVO, Mayo 2016.

Sobre SYL1001  

SYL1001 es un fármaco basado en ARNi que se administra en forma de gotas oculares sin conservantes que inhibe selectivamente la producción del receptor TRPV1. Estos receptores son canales iónicos mediadores de la transmisión del dolor a nivel ocular. SYL1001 es un oligonucleótido sintético de ARN de doble cadena de pequeño tamaño (siRNA) que actúa mediante un mecanismo de acción novedoso y altamente selectivo. Los estudios no clínicos realizados por Sylentis con SYL1001 han demostrado alta capacidad para inhibir esta diana específicamente y bloquear la percepción del dolor ocular en los animales tratados[i].

SYL1001 es un producto en desarrollo para la indicación del tratamiento o prevención del dolor ocular asociado al síndrome de ojo seco, y con potencial para desarrollarse para otras patologías que cursen con dolor ocular (herida en la córnea, cirugía refractiva, etc.)[ii],[iii],[iv].

Sobre ARN de interferencia (ARNi) 

ARN de interferencia (ARNi) es un proceso celular que ocurre de manera natural y que normaliza la expresión de ciertos genes regulando el desarrollo y la defensa innata en animales y plantas. Este proceso se utiliza en biotecnología para silenciar ARN mensajeros que codifican la proteína causante de la enfermedad. La aplicación terapéutica del ARNi está en auge dada la especificidad de silenciamiento de genes para una proteína particular en un determinado tejido y la ausencia de efectos secundarios. Este nuevo enfoque para el descubrimiento y desarrollo de fármacos es una tecnología prometedora que avanza rápidamente en el campo de la investigación traslacional[v].

Sobre Sylentis 

Sylentis es una empresa farmacéutica del Grupo PharmaMar (MSE:PHM), que desarrolla terapias innovadoras a partir de tecnologías de silenciamiento génico o ARNi. Esta tecnología permite el diseño de moléculas capaces de inhibir de manera selectiva la síntesis de proteínas causantes de enfermedad. Sylentis ha desarrollado numerosas terapias basadas en esta tecnología novedosa y en la actualidad cuenta con un sólido programa en oftalmología con dos candidatos en estudios clínicos de fase 2: bamosirán, para el tratamiento del glaucoma[vi] y SYL1001[ii],[iii],[iv], para el tratamiento del dolor ocular. Sylentis también investiga y desarrolla otros productos nuevos para el tratamiento de diferentes enfermedades oculares tales como alergias oculares y enfermedades de retina.
