Zusammenfassung:The present invention relates to antibodies against SIRPa that are suitable for use in anti-cancer therapy. The invention further relates to the use of the anti-SIRPa 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 SIRPalphal 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 SIRPbetalvl. In a third embodiment, the anti- SIRPalpha antibodies do not bind to SIRPgamma and do not bind to SIRPetalv2. In a fourth embodiment, the anti-SIRPalpha antibodies do not bind to SIRPbetalvl.
