A pan-allelic human SIRPα-blocking antibody, ES004-B5, promotes tumor killing by enhancing macrophage phagocytosis and subsequently inducing an effective T-cell response.
(PubMed, Antib Ther)
- "Unlike CD47-targeted agents, ES004-B5 exhibits an excellent safety profile in nonhuman primates. ES004-B5 has potential to be an important backbone for SIRPα-based combination therapy and/or bispecific antibodies, which will likely overcome the limitations of CD47-targeted agents encountered in clinical settings."

Treatment of anti-SIRPα in combination with anti-TAA exerts superior anti-tumor activity
(SITC 2022)
- "Through blocking CD47-induced inhibitory “don’t eat me” signals, ES004-B5 potently potentiates ADCP activity of anti-TAA antibodies like rituximab and cetuximab. Conclusions In summary, the functional anti-SIRPα mAb ES004-B5 has great potential to be used in combinations with multiple anti-TAA antibodies in cancer treatment. We are currently advancing the development of ES004-B5 into clinical candidate."
