Inebilizumab is derived from the mouse anti-human mAb HB12b, which had already shown impressive activity in depletion of B cells in transgenic mice carrying the human CD19 gene (hCD19 Tg)[1].
Inebilizumab potently depletes CD19-expressing B cells, including primary human B cells, B cell lines derived from multiple tumor types, and neoplastic B cells[1].
Inebilizumab demonstrates equal or better activity than Rituximab (HY-P9913) in depletion of human primary B cells in autologous ADCC assays and shows potent ADCC activity against human in vitro-differentiated and primary plasma cells[1].

Animal Model:huCD19/CD20 double Tg mice[2]
-
Dosage:0.5, 2, or 10 mg/kg
-
Administration:Tail vein injection, once
-
Result:Depleted B cells from blood and spleen, B-cell depletion in blood and spleen was maintained for more than 2 weeks after a single 10 mg/kg administration (better than Rituximab). Resulted in a substantial reduction (on average by 91.4% by day 3) in BM B220+muCD19+ B cells. Led to depletion of B cell by mouse macrophages.

Inebilizumab purchased from MedChemExpress. Usage Cited in: Acta Pharm Sin B. 2024 Oct;14(10):4560-4576. [Abstract]
Human PBMCs were treated with 100 nmol/L TP, 100 nmol/L TP-PEG, 10 nmol/L ADC-TP (IgG), 10 nmol/L Den, 10 nmol/L Inebilizumab (Ine), 10 nmol/L ADC-TP (Den), and 10 nmol/L ADC-TP (Ine) for 48 h, the frequencies of CD19+ B cells were analyzed by flow cytometry.
