Pasritamig
Based on 1 Customer Validation
Pasritamig (JNJ-78278343; KLCB-245) is a bispecific T-cell engager (BiTE) that targets the complex of human kallikrein KLK2 and CD3 receptor. Pasritamig redirects the cytotoxicity of T cells to KLK2-expressing tumor cells and induces T cell-mediated lysis of KLK2-expressing prostate cancer cells. Administered via subcutaneous injection, subcutaneous infusion or intravenous infusion, Pasritamig exhibits antitumor activity against metastatic castration-resistant prostate cancer. Pasritamig has a safety profile with an extremely low incidence of cytokine release syndrome and can be safely administered in an outpatient setting. Pasritamig is applicable to the research of metastatic castration-resistant prostate cancer.

Flow cytometric analysis of 1X106 Juakat cells with Pasritamig (HY-P991015, 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 IgG1 kappa (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
