Abstract
La invención se relaciona con anticuerpos biespecíficos novedosos, que comprenden al menos un dominio de unión capaz de unirse específicamente a CD47 y al menos un dominio de unión capaz de unirse específicamente a CD20. La invención además se relaciona con métodos para producir estos anticuerpos biespecíficos y con métodos para usar los mismos. Reivindicación 1: El anticuerpo biespecífico comprende (a) al menos un dominio de unión a antígeno capaz de unirse específicamente a CD47, y (b) y al menos un dominio de unión a antígeno capaz de unirse específicamente a CD20, en donde el dominio de unión a antígeno capaz de unirse específicamente a CD47 comprende una VH y una VL, en donde la VH comprende HCDR1 que comprende o consiste en la secuencia de aminoácidos como se establece en SEQ ID Nº 11, HCDR2 que comprende o consiste en la secuencia de aminoácidos como se establece en SEQ ID Nº 12, y HCDR3 que comprende o consiste en la secuencia de aminoácidos como se establece en SEQ ID Nº 13 o 17 o 21, y la VL comprende LCDR1 que comprende o consiste en la secuencia de aminoácidos como se establece en SEQ ID Nº 14, LCDR2 que comprende o consiste en la secuencia de aminoácidos como se establece en SEQ ID Nº 15 o 18 o 22, y LCDR3 que comprende o consiste en la secuencia de aminoácidos como se establece en SEQ ID Nº 16. Reivindicación 37: Un método para tratar o prevenir una enfermedad o afección en un sujeto, que comprende administrar a un individuo una cantidad eficaz del anticuerpo biespecífico de una cualquiera de las reivindicaciones 1 - 31, el ácido nucleico de la reivindicación 32, el vector de la reivindicación 33, la célula huésped de la reivindicación 34, o el inmunoconjugado de la reivindicación 35, o la composición farmacéutica de la reivindicación 36. Reivindicación 38: El método de la reivindicación 37, en donde la enfermedad o afección está relacionada con CD47 y/o relacionada con CD20. Reivindicación 39: El método de una cualquiera de las reivindicaciones 37 - 38, en donde la enfermedad o afección es cáncer.The invention relates to novel bispecific antibodies, comprising at least one binding domain capable of specifically binding to CD47 and at least one binding domain capable of specifically binding to CD20. The invention further relates to methods of producing these bispecific antibodies and to methods of using the same. Claim 1: The bispecific antibody comprises (a) at least one antigen binding domain capable of specifically binding to CD47, and (b) and at least one antigen binding domain capable of specifically binding to CD20, wherein the antigen binding capable of specifically binding to CD47 comprises a VH and a VL, wherein the VH comprises HCDR1 comprising or consisting of the amino acid sequence as set forth in SEQ ID NO: 11, HCDR2 comprising or consisting of the amino acid sequence as set forth in SEQ ID NO: 12, and HCDR3 comprising or consisting of the amino acid sequence as set forth in SEQ ID NO: 13 or 17 or 21, and VL comprising LCDR1 comprising or consisting of the amino acid sequence as set forth in SEQ ID NO: 14, LCDR2 comprising or consisting of the amino acid sequence as set forth in SEQ ID NO: 15 or 18 or 22, and LCDR3 comprising or consisting of the amino acid sequence as set forth in SEQ ID NO: 16. Claim 37: A method of treating or preventing a disease or condition in a subject, comprising administering to an individual an effective amount of the bispecific antibody of any one of claims 1 - 31, the nucleic acid of claim 32, the vector of the claim 33, the host cell of claim 34, or the immunoconjugate of claim 35, or the pharmaceutical composition of claim 36. Claim 38: The method of claim 37, wherein the disease or condition is related to CD47 and/ or related to CD20. Claim 39: The method of any one of claims 37-38, wherein the disease or condition is cancer.
