Summary

Open-label, Phase 1 Study of CD19 t-haNK as a Single Agent and in Combination With an IL-15 Superagonist (N-803) and Rituximab in Subjects With Relapsed/Refractory Non-Hodgkin Lymphoma. Up to 20 subjects will be enrolled and randomized 1:1 to 1 of 2 cohorts, as outlined below. The initial 3 subjects will be sequentially enrolled in a staggered fashion, with a 7 day interval between each subject to enable the capture and monitoring of any acute and subacute toxicities.

Conditions

  • Non Hodgkin's Lymphoma Refractory/Relapsed

Interventions

DRUG

N803

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

BIOLOGICAL

CD19t-haNK suspension

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).

DRUG

Cyclophosphamide

Cyclophosphamide is a synthetic antineoplastic drug chemically related to the nitrogen mustards. The chemical name for cyclophosphamide is 2-\[bis(2-chloroethyl)amino\]tetrahydro-2H-1,3,2-oxazaphosphorine 2-oxide monohydrate and has the molecular formula C7H15Cl2N2O2P•H2O and a molecular weight of 279.1.

DRUG

Fludarabine

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.

DRUG

Rituximab

Rituximab is a genetically engineered chimeric murine/human monoclonal IgG1 kappa antibody directed against the CD20 antigen. Rituximab has an approximate molecular weight of 145 kD and has a binding affinity for the CD20 antigen of approximately 8.0 nM.
