Surovatamig
Based on 1 Customer Validation
Surovatamig (AZD0486; TNB-486) is a fully human anti-CD19/CD3 IgG4 bispecific antibody. Surovatamig triggers T cell activation, releases cytotoxic granules, and induces T cell-dependent cellular cytotoxicity and tumor cell lysis. Surovatamig can reduces release of pro-inflammatory cytokines including IL-2, IFNγ, TNF. Surovatamig can be used for the research of cancer, such as B cell non-Hodgkin lymphoma.

Surovatamig specifically binds to CD19+ human B cell lines with an EC50 range of 1.2-5.2 nM and a cell surface Kd of 1.8 nM on Nalm6 cells[1].
Surovatamig (24 h) activates human CD4+ and CD8+ T cells in the presence of CD19+ RI-1 tumor cells, with EC50 values of 103.6 pM and 121.8 pM, respectively[1].
Surovatamig (5 day) induces proliferation of human CD4+ and CD8+ T cells in the presence of CD19+ RI-1 tumor cells, with EC50 values of 62.9 pM and 46.9 pM, respectively[1].
Surovatamig (0.0001-100 nM；48 h) triggers the release of cytotoxic granules (perforin and granzyme B) from human T cells in the presence of CD19+ RI-1 tumor cells[1].
Surovatamig (24-96 h) induces time-dependent lysis of primary human B cells via T cell redirection, with >90% lysis by 96 h and an EC50 range of 0.93-1.35 nM[1].
Surovatamig (48 h) induces concentration-dependent, CD19-specific lysis of multiple human B-NHL/ALL cell lines via both CD4+ and CD8+ T cell redirection, with EC50 values of 23.5 ± 11.5 pM (Raji) and 0.9 ± 0.2 nM (RI-1)[1].
Surovatamig (48 h) induces potent CD19-specific tumor cell lysis with significantly lower levels of proinflammatory cytokines (IL-2, IFNγ, TNF) and higher cytokine release EC50 values[1].

Surovatamig (1-100 μg/mouse; i.v.; every 4 days; 6 doses) induces dose-dependent tumor growth inhibition in a subcutaneous diffuse large B-cell lymphoma xenograft model, with the 100 μg/mouse dose achieving 88.52% tumor growth inhibition by day 40 post-implantation[1].
Surovatamig (0.4 mg/kg) delivers potent anti-tumor activity while inducing significantly reduced CRS-associated systemic cytokine release in a humanized disseminated DLBCL xenograft model[2].

Animal Model:CIEA-NOG (NOD.Cg-Prkdcscid IL2rgtm1Sug/JicTac) (female, 4-5 weeks old, disseminated Burkitt lymphoma xenograft via intravenous injection of 1×106 luciferase-expressing Raji cells)[1]
-
Dosage:10 ng/mouse; 100 ng/mouse; 1 μg/mouse; 10 μg/mouse
-
Administration:I.v.; every 5 days; 3 doses
-
Result:Showed dose-dependent tumor reduction relative to negative control after two treatments.
Cleared tumors to a similar extent as positive control at 100 ng, 1 μg, and 10 μg/mouse doses.
Showed tumor growth inhibition at 8 days post-implantation, but inhibition was not sustained by 14 days post-implantation at 10 ng/mouse dose.

Flow cytometric analysis of 1X106 Juakat cells with Surovatamig (HY-P991028, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. AF 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG4 (S228P) kappa (HY-P99003, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
