Idactamab (INT-001) is an IgG1-κ antibody with in vivo activity across a spectrum of hematological malignancies. Idactamab can be used for prepare MEDI7247, a potent and specific ADC, targeting ASCT2 (SLC1A5).

Idactamab 对不同血红素癌症细胞系具有抑制作用，IC₅₀ 为 0.05-65 ng/mL。
ASCT2 (SLC1A5) 是一种多通道、Na⁺ 依赖的中性氨基酸转运体，介导肿瘤生长和进展所需氨基酸的摄取。
