In the haematologic cancers, CAR NK‐92 cells targeting BCMA, CD7, CD19 and CD33 are being investigated as a therapeutic option for patients with multiple myeloma (NCT03940833), CD7‐positive haematologic malignancies (NCT02742727), CD19‐positive lymphoid malignancies (NCT02892695) and CD33‐positive acute myeloid leukaemias (NCT02944162). This evidence concerns the gene CD7 and plasma cell myeloma.
