-Keymed Biosciences anuncia la dosificación del primer paciente del ensayo de fase I del anticuerpo biespecífico CM350

CHENGDU, China, 10 de junio de 2022 /PRNewswire/ -- Keymed Biosciences (HKEX: 02162) ha anunciado hoy que se ha administrado la dosis al primer paciente en el ensayo de fase I de CM350. CM350 es un anticuerpo biespecífico GPC3xCD3 desarrollado por la Compañía para el tratamiento de tumores sólidos. El ensayo de fase I se está llevando a cabo para evaluar la seguridad, la tolerabilidad, la farmacocinética, la farmacodinámica y la actividad antitumoral preliminar de CM350 en pacientes con tumores sólidos.

Acerca de CM350

Desarrollado sobre la plataforma de anticuerpos biespecíficos Novel T cell engager (nTCE), propiedad de Keymed, CM350 es el primer anticuerpo biespecífico GPC3xCD3 que entra en desarrollo clínico en China y el segundo en el mundo. La expresión de GPC3 se encuentra raramente en los tejidos humanos adultos normales, pero está altamente regulada en una variedad de tumores sólidos, incluyendo el carcinoma hepatocelular, el cáncer de pulmón, el cáncer gástrico y el cáncer de esófago, lo que sugiere que GPC3 es una diana ideal para la terapéutica de múltiples tumores sólidos, especialmente el carcinoma hepatocelular.

Los estudios preclínicos han demostrado que CM350 podía eliminar eficazmente las células tumorales positivas GPC3 mediante la citotoxicidad celular dependiente de células T (TDCC) y ejercer una actividad antitumoral muy potente en modelos tumorales de ratón. Basándose en las ventajas de la plataforma de anticuerpos biespecíficos nTCE, CM350 está optimizado para matar células tumorales de forma altamente eficaz con un perfil de seguridad favorable, minimizando el efecto no específico sobre las células normales y la liberación de citoquinas. Por lo tanto, CM350 puede proporcionar una opción de tratamiento prometedora para los pacientes con cáncer con una mejor eficacia y seguridad manejable.

Acerca de la plataforma de anticuerpos biespecíficos nTCE

Novel T cell engager (nTCE) es una plataforma tecnológica de anticuerpos biespecíficos CD3 desarrollada por Keymed con derechos de propiedad. Los anticuerpos desarrollados por la plataforma nTCE pueden eliminar eficazmente las células tumorales por TDCC con un efecto no específico minimizado sobre las células normales y la liberación de citoquinas, reduciendo así la aparición del posible síndrome de liberación de citoquinas en el tratamiento clínico.

Los anticuerpos desarrollados por nuestra plataforma nTCE tienen estructuras similares a las de los anticuerpos nativos con perfiles farmacocinéticos favoritos. A través de la sofisticada tecnología de ingeniería de proteínas, la plataforma nTCE permite el emparejamiento eficiente de las cadenas pesadas/ligeras afines del anticuerpo biespecífico con alto rendimiento y baja agregación. Utilizando nuestra avanzada plataforma nTCE, Keymed ha desarrollado una serie de anticuerpos biespecíficos que se encuentran actualmente en las fases de desarrollo preclínico y clínico.
