  • Patent number: 11643461
    Abstract: Humanized, mouse or chimeric anti-CD47 monoclonal antibodies are provided. The antibodies bind to human glycosylated and deglycosylated CD47 with an optimized Koff value, they disrupt the human CD47-SIRP? interaction, and find use in various therapeutic, preventive or diagnostic methods. The invention includes isolated antibodies and derivatives and fragments thereof, pharmaceutical formulations comprising one or more of the humanized or chimeric anti-CD47 monoclonal antibodies; and cell lines that produce these monoclonal antibodies. Also provided are amino acid and nucleotide sequences of the antibodies.

  • Publication number: 20230001006
    Abstract: The present invention relates to an antibody drug conjugate (ADC) of general formula (I) (D-Lk1-C(O)-Lk2-C2H4—NH-Lk3)n-Ab. A pharmaceutical composition comprising, in a pharmaceutically acceptable medium, the said ADC is also concerned by the present invention, as well as the use of this ADC or composition as a medicament, and in particular in the prevention and/or the treatment of an anti-Müllerian hormone type II receptor (AMHRII) expressing cancer in an individual.

  • Publication number: 20110251085
    Abstract: The present invention relates to the field of virology. More precisely, the invention provides a method of determining the ability of a test compound to modulate the biological activity of a variant of a target protein, wherein said test compound is previously known to modulate the biological activity of said protein. This invention is useful to determine whether a drug candidate, such as anti-viral compounds (eg. against hepatitis C virus: NS5B, NS3), active against a target protein is active against a variant of said protein (eg. polymorphisms, genotypes or mutants).
