The present disclosure provides BCMA binding molecules that specifically bind to human BCMA, conjugates comprising the BCMA binding molecules, and pharmaceutical compositions comprising the BCMA binding molecules and the conjugates. The disclosure further provides methods of using the BCMA binding molecules to treat cancers that express cell surface BCMA. The disclosure yet further provides recombinant host cells engineered to express the BCMA binding molecules and methods of producing the BCMA binding molecules by culturing the host cells under conditions in which the BCMA binding molecules are expressed.本揭露提供了特異性結合人BCMA的BCMA結合分子、包含該BCMA結合分子的軛合物、和包含該BCMA結合分子和所述軛合物的藥物組成物。本揭露進一步提供了使用該BCMA結合分子治療表現細胞表面BCMA的癌症之方法。本揭露又進一步提供了被工程化以表現該BCMA結合分子的重組宿主細胞，以及在表現該BCMA結合分子的條件下藉由培養所述宿主細胞產生該BCMA結合分子之方法。
