  • Project profile
    Project name: CD19 mAb
    Indications: Autoimmune diseases/ B cell malignancies
    Research phase: Apply for IND
    Cooperation demands: License-out or co-development
  • Highlights

    1. Clear MoA.

    (1) CD19 is expressed on normal B cells, but it is not found on hematopoietic stem cells, and other healthy tissues.

    (2) CD19 is expressed on nearly all B-cell malignancies: including ALL, CLL, many NHL (>95%).

    (3) Long-lived plasma cells produce autoantibodies, lack CD20 but majority express CD19.
