About this study

Official title: Lymphodepleting Chemotherapy With Rituximab and Allogeneic Natural Killer Cells for Patients With Refractory Lymphoid Malignancies (MT2009-15)

In this study the investigators investigate a cell therapy strategy that could harness allogeneic effectors that can potentially mediate anti-lymphoma effect. The investigators have designed a novel lymphodepleting conditioning regimen followed by infusion of donor-derived natural killer (NK) cells and interleukin-2 (IL-2) for patients with refractory lymphoid malignancies.

Read the detailed description

This is a single center phase II trial designated to expand donor NK cells and induce remissions in patients with refractory non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) using chemotherapy followed by haploidentical NK cells and IL2.

Primary Objective is to evaluate the objective response rate (PR+CR) at 2 months post haploidentical NK cell infusion in patients with refractory Non Hodgkin's Lymphoma (NHL) and chronic lymphocytic leukemia (CLL).

Secondary Objective is to 1) evaluate the safety and tolerability of lymphodepleting chemotherapy, rituximab, and methylprednisone as determined by incidence of serious adverse events; 2) evaluate in vivo expansion of allogeneic donor NK cells at day 14; 3) determine time to progression

Exploratory Objective is to 1) correlate clinical response with frequencies of peripheral blood T reg cells after chemotherapy; 2) correlate clinical response with donor KIR-B-content score determined by genotype; 3) monitor phenotypic and functional characteristics of natural killer cells and regulatory T cells in vivo; 4) correlate clinical response with donor FcR polymorphism.

  • Pre-NK cell infusion chemotherapeutic regimen consist of 1) Rituximab 375mg/m2 IV weekly x 4, start day -7; 2) Fludarabine 25 mg/m2 IV day -6 through day -2; 3) Cyclophosphamide 60mg/kg IV day -5; 4) Methylprednisolone 1 mg/kg day -2 through day +9.
  • NK cell infusion using IL2 activated donor NK cells 1.5 to 8 x 107 cells/kg IV day 0
  • IL2 SC 9 million IU every other day x 6 doses over 2 weeks begin 1 to 24 hours after NK cell infusion. If weight < 45 kilograms, give IL-2 at 5 million units/m2 on same schedule

Accrual Goal: Up to 17 patients will be enrolled

Being tested
Rituximab, Interleukin-2, Natural killer cells, Cyclophosphamide, Methylprednisolone

What is being measured

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

  1. Number of Patients With an Objective Response

    The number of patients with a partial response (PR) or complete response (CR). For patients with non-hodgkin's lymphoma: CR - complete disappearance of all detectable clinical evidence of disease and disease-related symptoms. PR - at least a 50% decrease in sum of the product of the diameters of up to six of the largest dominant nodes or nodal masses. For patients with chronic lymphocytic leukemia: CR - disappearance of all palpable disease, normalization of the blood counts without transfusions, bone marrow aspirate lymphocyte percentage < 30%, and no evidence of disease on bone marrow biopsy. PR - 50% or more reduction in palpable disease as well as one or more of the remaining features: neutrophils >= 1.5 × 109/L or 50% improvement over baseline, platelets more than 100 × 109/L or 50% improvement over baseline, and hemoglobin more than 11.0 g/dL or 50% improvement over baseline without transfusions.

    Measured: Month 2 Post Infusion

Secondary outcomes (3)
  1. Serious Adverse Events

    Number of participants experiencing serious adverse events that occur during study. Adverse event collection for the purposes of this study will focus on targeted adverse events and unexpected adverse events at specific time points in relation to the NK cell infusion and post infusion IL2 injections.

    Measured: Day 1 through Month 12

  2. Time to Disease Progression

    Cumulative incidence will be used to determine time to disease progression.

    Measured: Day 1 through Month 12

  3. Patients With Expansion of NK Cells

    Number of patients who experience in vivo expansion of allogeneic donor natural killer (NK) cells.

    Measured: Day 14

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Rituximab, Interleukin-2 and Natural killer cells in people with Non-Hodgkin Lymphoma and Chronic Lymphocytic Leukemia, run by Masonic Cancer Center, University of Minnesota at 1 site 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 11 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: finished, as of the sponsor's last update on 6 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 May 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients With an Objective Response (time frame: Month 2 Post Infusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01181258, which also lists 1 linked publication.

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 6 Feb 2018.
