Study: NCT05618925

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: N803
Description: nogapendekin alfa inbakicept (also known as ALT-803; recombinant human superagonist interleukin-15 (IL-15) complex \[also known as IL 15N72D:IL-15RαSu/IgG1 Fc complex\])

Intervention type: BIOLOGICAL
Group type: EXPERIMENTAL
Intervention: CD19t-haNK suspension
Description: Derived from the parental NK-92 (aNK) cell line, CD19 t-haNK is a human, allogeneic, NK cell line that has been engineered to express a CAR targeting CD19. Similar to the haNK cell line, CD19 t haNK has also been engineered to produce endoplasmic reticulum-retained IL 2 and the high-affinity (158V) variant of the Fcγ receptor (FcγRIIIa/CD16a), and thereby has enhanced CD16-targeted ADCC capabilities. CD19 t-haNK is similar to PD L1 t-haNK, differing only in the CAR that is expressed (CD19 vs PD-L1).

Intervention: Fludarabine
Description: Fludarabine phosphate is a fluorinated nucleotide analog of the antiviral agent vidarabine, 9-β-D-arabinofuranosyladenine (ara-A) that is relatively resistant to deamination by adenosine deaminase. The chemical name for fludarabine phosphate is 9H-Purin-6-amine, 2-fluoro-9-(5-0-phosphono β-D-arabino-furanosyl) (2-fluoro-ara-AMP). The molecular formula of fludarabine phosphate is C10H13FN5O7P and it has a molecular weight of 365.2.
