Study for Subjects With Relapsed/Refractory Non- Hodgkin Lymphoma
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.

Detailed Description
This is a phase 1, first-in-human (FIH), open-label study to evaluate the safety of CD19 t-haNK as a single agent and the safety and preliminary efficacy of CD19 t haNK in combination with rituximab only and in combination with rituximab and N 803 in subjects with R/R NHL.
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.
Subjects in both cohorts will initially receive lymphodepleting chemotherapy followed by a single 4 week cycle of the CD19 t haNK single-agent regimen. Following a 1-week rest period, subjects will then receive lymphodepleting chemotherapy followed by a single 4-week cycle of CD19 t-haNK in combination with rituximab (cohort A) or in combination with rituximab and N-803 (cohort B). Following a second 1-week rest period, subjects will receive up to 4 repeated 4 week cycles of CD19 t haNK in combination with rituximab (cohort A) or in combination with rituximab and N 803 (cohort B) without lymphodepleting chemotherapy.

- Current chronic daily treatment (continuous for > 3 months) with systemic corticosteroids (dose equivalent to or greater than 10 mg/day methylprednisolone), excluding inhaled steroids. Short-term steroid use to prevent IV contrast allergic reaction or anaphylaxis in subjects who have known contrast allergies is allowed.
- Currently taking any medication(s) (herbal or prescribed) known to have an adverse drug reaction with any of the study medications.
- History of human immunodeficiency virus (HIV) with current CD4+ T-cell count < 500 cells/μL..
- Chronic carriers of hepatitis B virus (HBV) infection that is currently hepatitis B surface antigen (HBsAg) positive. NOTE: Subjects who have a history of HIV/HBV or who are seropositive will require testing for Infectious Disease Markers (IDM).

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).
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.
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.
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.
