About this study

Official title: 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.

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • N803Drug

    Also called Anktiva

    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])

  • CD19t-haNK suspensionBiological

    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).

  • CyclophosphamideDrug

    Also called Cytoxan

    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.

  • FludarabineDrug

    Also called Fludara

    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.

  • RituximabDrug

    Also called Rituxan

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary Outcome Measures

    Safety of CD19 t-haNK will be assessed by incidence and severity of TEAEs and SAEs, as well as incidence of clinically significant in safety laboratory tests and vital signs

    Measured: within 30 days after each cell infusion

Secondary outcomes (1)
  1. Secondary Outcome measures

    Overall response rate (ORR) will be assessed in accordance with Lymphoma Response to Immunomodulatory Therapy Criteria (LYRIC) from first CD19 t-haNK infusion to death of last follow-up

    Measured: Within 12 months after first cell infusion

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing N803, CD19t-haNK suspension and Cyclophosphamide in people with Non Hodgkin's Lymphoma Refractory/Relapsed, run by ImmunityBio, Inc. at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 1 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Mark Nelson (213 414 3566, mark.nelson@immunitybio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Outcome Measures (time frame: within 30 days after each cell infusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Apr 2026.
