- IO Biotech presenta, en la reunión anual de 2019 de la Asociación Estadounidense de Investigación Oncológica, datos relativos a una vacuna inmunomoduladora derivada de la CCL22

--A la vista de lo prometedor de la información obtenida, se planea la realización de ensayos clínicos en seres humanos--

COPENHAGUE, Dinamarca, 2 de abril de 2019 /PRNewswire/ -- IO Biotech, empresa biofarmacéutica especializada en las fases clínicas y que se dedica a elaborar tratamientos novedosos e inmunomoduladores contra el cáncer a partir de su tecnología patentada T-win®, presentó un conjunto de datos preclínicos referidos al potencial terapéutico de una vacuna inmunomoduladora derivada de la CCL22. Estos datos se han presentado hoy en la reunión anual de 2019 de la Asociación Estadounidense de Investigación Oncológica (American Association for Cancer Research), celebrada en Atlanta (Georgia).

La CCL22 es una quimiocina secretada por macrófagos que ejerce funciones inmunosupresoras mediante el reclutamiento de linfocitos T reguladores que actúan en el microentorno tumoral (MET), Las células expresan la CCL22 en el MET de varios tipos de cáncer, como el melanoma y los cánceres de mama, pulmón y páncreas; asimismo, se cree que la CCL22 interviene en la inmunosupresión reclutando linfocitos T reguladores CD4+.

Se ha descrito anteriormente que los linfocitos T propios de la CCL22 que presentan los enfermos de cáncer pueden eliminar las células tumorales que expresan la CCL22 y es posible que la activación de dichos linfocitos influya directamente en la concentración de quimiocina en el MET, lo que apunta a que la CCL22 podría constituir una diana de interés para una vacuna inmunomoduladora. En este cartel se explica que IO Biotech ha seguido realizando pruebas sobre este concepto y ha demostrado que la vacuna derivada de la CCL22 interviene en la inmunidad antitumoral en dos modelos neoplásicos murinos y, lo que es más, con una evaluación de la expresión genética en los tumores se puso de manifiesto que dicha vacuna produce una disminución directa del crecimiento de estas neoplasias por reducción de la expresión de la CCL22, junto con otras moléculas inmunosupresoras como la IDO1, en el MET. En conclusión, tales hallazgos ofrecen una base teórica para la creación de una inmunoterapia oncológica innovadora dirigida al MET inmunosupresor.

"Estos descubrimientos apuntan a que es posible abordar el microentorno tumoral e intervenir en él actuando sobre las células que expresan la CCL22", manifestó la doctora Mai-Britt Zocca, consejera delegada de IO Biotech. "Ello nos va a permitir seguir estudiando el potencial de la vacuna derivada de esta quimiocina y a lo largo del año que viene esperamos obtener más datos preclínicos para a continuación iniciar los primeros ensayos en seres humanos".

IO Biotech dispone de un compuesto, el IO140, que va dirigido contra las células que expresan la CCL22 y se encuentra en fase de desarrollo preclínico.

Acerca de la plataforma tecnológica T-win
La plataforma tecnológica T-win, patentada por IO Biotech, permite la identificación de compuestos que posean un mecanismo de acción dual que, por una parte, vayan dirigidos contra las células inmunosupresoras y tumorales y las supriman directamente y que, por otra, activen indirectamente otros efectores T, para producir así una respuesta antitumoral más potente.

Acerca de IO Biotech
IO Biotech es una empresa biotecnológica especializada en las fases clínicas y que se dedica a elaborar tratamientos inmunitarios revolucionarios para el ámbito oncológico. Los tratamientos antineoplásicos inmunomoduladores que tiene en proceso de investigación, los primeros de su clase, se elaboran gracias a una plataforma tecnológica de características singulares, la T-win, que permite la activación de linfocitos T dirigidos específicamente contra las moléculas inmunosupresoras. En este sentido, IO Biotech cuenta con un sólido historial de avance en materia de compuestos preclínicos y clínicos; los dos más importantes que van dirigidos contra el IDO y el PD-L1 se encuentran en fase de desarrollo clínico y la empresa tiene en proyecto otros que están en la fase preclínica.
