  • Patent number: 11873338
    Abstract: The disclosure relates to means and methods of treating a subject for a CLEC12A positive cancer. In some embodiments the method comprises treating the subject in need thereof with two or more administrations of a bispecific antibody that binds CD3 and CLEC12A, wherein in a first administration an first amount of the bispecific antibody is administered and wherein in each of the subsequent administrations the amount of bispecific antibody is higher than the amount of bispecific antibody in the first administration. In some embodiments CLEC12A positive cancer treatment methods are provided at intervals and dosing regimens that spare hemopoietic stem cell compartment allowing for recovery of normal CLEC12A positive hemopoietic cells.

  • Publication number: 20220127375
    Abstract: The invention relates to means and methods of producing at least two antibodies. Methods may include providing cells with nucleic acid that encodes the antibodies; culturing said cells; collecting the antibodies from the culture; and separating produced antibodies from half antibodies by ion exchange chromatography (IEX). In some embodiments the antibodies exhibit IEX retention times that that deviate by 10% or less from the average of the retention times of the individual antibodies under the IEX conditions used. The invention also relates to compositions of antibodies thus produced. In some aspects the invention relates to compositions comprising 2-10 recombinant antibodies characterized in that the IEX retention times of at least two of said antibodies deviate by 10% or less from the average of the retention times of the individual antibodies under the IEX conditions.
