Patent number: 11274159Abstract: The present invention relates to antibodies against SIRP? that are suitable for use in anti-cancer therapy. The invention further relates to the use of the anti-SIRP? antibodies in the treatment of human solid tumours and haematological malignancies, optionally in combination with other anti-cancer therapeutics. The anti-SIRPalpha antibodies described are more specific than known anti-SIRPalpha antibodies, whereas they show excellent affinity for both SIRPalpha1 and SIRPalphaBIT. In one embodiment the anti-SIRPalpha antibodies do not bind to SIRPgamma. In a second embodiment, the anti-SIRPalpha antibodies do not bind to SIRPgamma and do not bind to SIRPbeta1v1. In a third embodiment, the anti-SIRPalpha antibodies do not bind to SIRPgamma and do not bind to SIRPeta1v2. In a fourth embodiment, the anti-SIRPalpha antibodies do not bind to SIRPbeta1v1.Type: GrantFiled: May 15, 2018Date of Patent: March 15, 2022Assignee: Byondis B.V.Inventors: Gijsbertus Franciscus Maria Verheijden, Gerard Rouwendal, Roland Jan Arends, Timo Kars Van Den Berg, Hanke Lottie Matlung, Katarina Franke
