SOFIA, Bulgaria, 20 de junio de 2023 /PRNewswire/ -- Longbio Pharma (Suzhou) Co., Ltd. (abreviado como "Longbio Pharma"), una compañía farmacéutica que desarrolla medicamentos para el tratamiento de la alergia, el asma, la oftalmología y otras enfermedades autoinmunes, anunció los datos de la fase I de LP-003 (nueva generación de anticuerpos anti-IgE) en el 29º Congreso de la Sociedad Europea de Rinología (ERS2023)

Título del póster (premiado como mejor póster): Un estudio de fase 1 en sujetos sanos de LP-003, un nuevo anticuerpo anti-IgE de acción prolongada para la rinitis alérgica 

ID de envío de resúmenes: 1209

Resultados: LP-003 tiene una alta afinidad de unión a IgE (>100 veces) sin unión fuera del objetivo, inhibición más potente de FcεRI y FcεRII/CD23 en comparación con omalizumab.

En un estudio clínico de fase I aleatorio, doble ciego (CTR20221413), 32 sujetos sanos se dividieron al azar en cinco grupos para recibir una dosis intravenosa única de 0,3 mg/kg, 1 mg/kg, 3 mg/kg, 6 mg/ kg y 10 mg/kg respectivamente. Se evaluó el perfil de seguridad, farmacocinética y farmacodinámica (niveles de IgE libre).

LP-003 exhibió una característica farmacocinética no lineal con T1/2 que varió de 46,3 días a 75,6 días, que es aproximadamente 2~3 veces mayor que Omalizumab. Además, la IgE libre se suprimió por debajo del rango de detección durante más de 70 días en el grupo de 1 mg/kg (excepto uno con un nivel de referencia alto de IgE) al grupo de 10 mg/kg.

LP-003 parece mostrar un buen perfil de seguridad. No se informó ningún TEAE de grado 3 o superior, lo que establece una base sólida para una mayor investigación y avance.

"Esta presentación de póster brinda la oportunidad de compartir nuestros primeros datos en humanos para LP-003 con la comunidad internacional de alergias. Y los datos de la Fase I son realmente emocionantes y representan un hito importante", exclamó el Dr. Sun, Nai-chau, cofundador de Longbio Pharma, también inventor de omalizumab y cofundador de Tanox Inc. "Los resultados positivos refuerzan nuestra creencia en el mejor potencial de su clase de LP-003 y su capacidad para abordar las necesidades urgentes de los pacientes que padecen enfermedades alérgicas, como la rinitis alérgica".

Longbio Pharma ha iniciado ensayos clínicos de Fase II para aprovechar los prometedores resultados obtenidos en la Fase I y recopilar datos más completos. La compañía también busca activamente colaboraciones y asociaciones con partes interesadas de la industria para acelerar el desarrollo y la comercialización de LP-003, con el objetivo final de proporcionar una opción de tratamiento revolucionaria para los pacientes de todo el mundo.

Acerca de LP-003
LP-003, un nuevo anticuerpo anti-IgE fue generado, humanizado y diseñado por el Dr. Sun, Nai-chau, inventor de Omalizumab y cofundador de Tanox. Basado en los más de 30 años de experiencia en el objetivo de IgE, el Dr. Sun desarrolló una nueva generación de anticuerpos anti-IgE (LP-003). Los datos actuales muestran que LP-003 tiene el potencial de convertirse en el mejor tratamiento de su clase.

Están en curso dos estudios de fase II, de rinitis alérgica y urticaria espontánea crónica. La compañía espera tener el resultado principal del estudio LP-003 de Fase II para fines de 2023.

Acerca de Longbio Pharma
LongBio Pharma, una empresa de biotecnología ubicada en Shanghai/Changshu, China, se enfoca en enfermedades autoinmunes y del complemento, al servicio de los pacientes y la sociedad.
