CD56+CD3- NK Cells Following Allogeneic Stem Cell Transplantation

June 3, 2015 updated by: Imperial College London

Safety and Toxicity of Escalating Doses of Adoptively Infused ex Vivo Selected CD56+CD3- NK Cells on Day 7 Following Allogeneic Stem Cell Transplantation in Patients With Hematological Malignancies.

The investigators propose a nonrandomized, Phase I study to assess the safety of infusion of NK cells that will be selected from sibling donors and infused to patients with hematological malignancies early following allogeneic stem cell transplantation.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Allogeneic hematopoietic stem cell transplantation (HSCT) is a very effective treatment for a number of hematological malignancies but relapse remains a major problem, especially in patients with high risk disease. Natural killer (NK) cells are immune cells that recognize and kill virally infected cells and tumor cells. NK cells are identified by the expression of the CD56 surface antigen and the lack of CD3. Their ability to kill tumor cells makes them promising to evaluate as effector cells for immunotherapy.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Patients undergoing an allogeneic HSCT from a sibling donor, as treatment for a hematological malignancy. The conditioning regimen, and in particular whether ablative or non ablative, will not be considered in the criteria for recruitment
  2. Patient and donor Age >18 years
  3. Patients and donors must have signed an informed consent form
  4. The donor must be willing and capable of donating lymphocytes for NK selection using apheresis techniques
  5. Donor must be fit to undergo leukapheresis

Exclusion Criteria:

  1. Life expectancy < 3 months
  2. ECOG performance status 3 or 4
  3. Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, life threatening cardiac arrhythmia
  4. Patients will not be eligible if they receive in vivo T depletion with ATG, ALG or campath-1H
  5. HIV-positive patients
  6. Psychiatric illness/social situations that would limit compliance with study requirements and ability to comprehend the investigational nature of the study and provide informed consent

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety and toxicity donor CD56+CD3- NK cells
Time Frame: Day 28 post NK cell infusion
To evaluate the safety and toxicity of escalating doses of ex vivo selected donor CD56+CD3- NK cells, adoptively infused on day 7 following sibling allogeneic stem cell transplantation in patients with hematological malignancies. We will specifically look for the proportion of patients who develop infusion related toxicity. Toxicity will be defined as per the Common Terminology Criteria for Adverse Events v3.0 (CTCAE).
Day 28 post NK cell infusion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Donor neutrophil and platelet engraftment
Time Frame: Day 28 post stem cell infusion
Donor neutrophil engraftment (Neut > 0.5 x10^9/L) and platelet engraftment (Plt > 20 x10^9/L)
Day 28 post stem cell infusion
Rates of acute GVHD (grade 2-4)
Time Frame: Day 100 post stem cell infusion
Risk of acute GVHD
Day 100 post stem cell infusion
Relapse rate
Time Frame: 1 year post stem cell infusion
Relapse
1 year post stem cell infusion

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 1, 2011

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
