Protein expression analysis in NK cells
Strain specific FCGR3A expression analysis in wild-type CB-17 SCID mice and homozygous B-hFCGR3A(CB-17 SCID) by flow cytometry. Splenocytes were collected from wild-type CB-17 SCID mice(+/+) and homozygous B-hFCGR3A mice(CB-17 SCID) (H/H). Mouse FCGRIV was not detectable in NK cells of wild-type CB-17 SCID mice.

Analysis of spleen leukocytes subpopulation in B-hCD16A mice(CB-17 SCID)
Analysis of spleen leukocyte subpopulations by FACS. Splenocytes were isolated from female wild-type CB-17 SCID and B-hCD16A mice(CB-17 SCID) (n=3, 8-week-old). Flow cytometry analysis of the splenocytes was performed to assess leukocyte subpopulations. A. Representative FACS plots. Single live cells were gated for the CD45+ population and used for further analysis as indicated here. B. Results of FACS analysis. Percent of NK cells, dendritic cells, granulocytes, monocytes and macrophages in homozygous B-hCD16A mice(CB-17 SCID) were similar to those in the CB-17 SCID mice, demonstrating that CD16A humanized does not change the overall development, differentiation or distribution of these cell types in spleen. Values are expressed as mean ± SEM.

Subcutaneous CDX tumor growth of B-hHep3B-Luc cells in B-hCD16A mice(CB-17 SCID). B-hHep3B-Luc cells(8x106) were subcutaneously implanted into B-hCD16A mice(CB-17 SCID) (female, 8-week-old, n=6). Tumor volume and body weight were measured twice a week. (A) Average tumor volume ± SEM. (B) Body weight (Mean± SEM). Volume was expressed in mm3 using the formula: V=0.5 X long diameter X short diameter2. As shown in panel A, B-hHep3B-Luc cells were able to establish tumors in B-hCD16A mice(CB-17 SCID) and can be used for efficacy studies.
In situ CDX tumor growth of B-hHep3B-Luc cells in B-hCD16A mice(CB-17 SCID). B-hHep3B-Luc cells(8x106) were in situ implanted into B-hCD16A mice(CB-17 SCID) (female, 8-week-old, n=6). Tumor fluorescence intensity and body weight were measured twice a week. (A) Average tumor volume ± SEM. (B) Body weight (Mean± SEM). As shown in panel A, B-hHep3B-Luc cells were able to establish tumors in B-hCD16A mice(CB-17 SCID) and can be used for efficacy studies.
Subcutaneous CDX tumor growth in B-hCD16A mice(CB-17 SCID). HC116 (5x106), K-562 (1x106) and NCI-N87 (1x107) were subcutaneously implanted into B-hCD16A mice(CB-17 SCID) (female, 8-week-old, n=6). Tumor volume and body weight were measured twice a week. (A) Average tumor volume ± SEM. (B) Body weight (Mean± SEM). Volume was expressed in mm3 using the formula: V=0.5 X long diameter X short diameter2. As shown in panel A, HCT116, K-562 and NCI-N87 were able to establish tumors in B-hCD16A mice(CB-17 SCID) and can be used for efficacy studies.
In vivo efficacy of anti-human CLDN18.2 antibody
Antitumor activity of anti-human CLDN18.2 antibody in B-hCD16A mice (CB-17 SCID) bearing B-hCLDN18.2 BxPC-3 cells. (A) Anti-hCLDN18.2 antibody inhibited tumor growth. Human pancreas B-hCLDN18.2 BxPC-3 cells were subcutaneously implanted into homozygous B-hCD16A mice (CB-17 SCID) (female, 10 week-old, n=6). Mice were grouped when tumor volume reached approximately 100 mm3, at which time they were treated with antibodies in panel A. (B) Body weight changes during treatment. As shown in panel, B-hCD16A mice (CB-17 SCID) bearing B-hCLDN18.2 BxPC-3 cells provide a powerful preclinical model for in vivo evaluation of anti-CLDN18.2 antibodies.
