CD3/CD19 Depleted or CD3 Depleted/CD56 Selected Haploid Donor Natural Killer Cell Treatment in Older AML in First Complete Remission

Infused on Day 0. The final CD3-/CD19- product must contain at least 20% NK cells based on previous studies using this cell product processing technique. The entire cell product will be administered except in cases where the T cell count exceeds the T cell infusion threshold. In such situations, the product volume will be adjusted to meet the lot release criteria.

Infused on Day 0. The final CD3-/CD56+ product must contain at least 70% NK cells based on a previous study using this cell product processing technique. The entire cell product will be administered except in cases where the T cell count exceeds the T cell infusion threshold. In such situations, the product volume will be adjusted to meet the lot release criteria.

In combination used to simultaneously deplete CD3+ cells to remove T-lymphocytes and deplete CD19+ cells to remove B-lymphocytes (CD3-/CD19-). The entire cell product will be administered except in cases where the T cell count exceeds the T cell infusion threshold. In such situations, the product volume will be adjusted to meet the lot release criteria.

CliniMACS® CD3 and CD19 Reagent System will be used in addition to CliniMACS® CD56 Reagent System to enrich CD56+ NK cells. The entire cell product will be administered except in cases where the T cell count exceeds the T cell infusion threshold. In such situations, the product volume will be adjusted to meet the lot release criteria.
