Emactuzumab  (Synonyms: 依米妥珠单抗; RG 7155; RO 5509554)

Emactuzumab(RG 7155) is a specific monoclonal antibody that inhibits colonystimulating factor 1 receptor (CSF1R) activation. Emactuzumab has high affinity for CSF-1R with K_i value of 0.2 nM to blocks CSF-1R dimerization. Emactuzumab can be used for the research of several diseases, such as diffuse-type tenosynovial giant cell tumour (dt-GCT) ^[1][2].

Emactuzumab (RG 7155) binds to human and cynomolgus CSF-1R with high affinity (K_d = 0.2 nM) to blocks CSF-1R dimerization^[2].
RG7155 (0-10 μg/mL, 7 days) potently inhibited the viability of CSF-1-differentiated macrophages with an IC₅₀ of 0.3 nM by inducing cell death^[2].
RG7155 (30 μg/mL, 6 days) induces cell death of in vitro-differentiated human M2-like macrophages^[2].

Emactuzumab(RG 7155) (i.v.; 0.1、1、10、30 and 100 mg/kg; once) increases CSF-1 concentration in nonhuman primates’ peripheral blood^[2].
RG7155 (i.v.; 0, 30, and 100 mg/kg; once weekly; for 2 weeks) depletes CSF-1R⁺CD163⁺ macrophages in vivo^[2].
