A Study of Modified Stem Cells in Stable Ischemic Stroke

December 19, 2016 updated by: SanBio, Inc.

A Phase 1/2A Study of the Safety and Efficacy of Modified Stromal Cells (SB623) in Patients With Stable Ischemic Stroke

The primary purpose of the clinical study is to determine the safety of a modified stem cell SB623 when administered to chronic, stable ischemic stroke patients. A second purpose is to determine whether SB623 might improve stroke symptoms. Chronic, stable ischemic stroke patients must be between 6 and 60 months after their stroke, and with only this one prior stroke, and and with no further improvement from physical therapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Chronic, stable stroke patients have no existing alternative treatments after rehabilitation therapy. SB623, a modified stem cell preparation, has been shown to improve motor function when administered in animal models of stable stroke. Safety studies in animals have shown no adverse events attributed to SB623. Patients who meet the entry criteria for this study will have regular examinations, radiological evaluations (CT, MRI, PET), and be followed for two years. Regular neurological evaluations will also be done using standard questionnaires, with occasional video recording if improvements are evident. Key entry criteria for this study, in addition to 6-60 months post-ischemic stroke, include moderately severe symptoms--e.g., difficulty standing or walking, and/or difficulty using arms or hands, and/or speech impediments.

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

14 years to 71 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • No significant further improvement with physical therapy/rehabilitation
  • Able and willing to undergo computed tomography (CT), magnetic resonance imaging (MRI), and positron-emission tomography (PET) scans of the head

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: SB623
Administration of modified stem cells, SB623
Biological: SB623
SB623, a modified stem-cell product, will be administered at 3 dose levels. Each patient in one of three groups will be given a dose of 2.5, 5.0, or 10 million cells once. Each group will be completed before going to the next higher-dose group.

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
Time Frame: Two years
Safety will be evaluated using the WHO safety criteria, by periodic MRIs, frequent laboratory monitoring, and by periodic measurements of possible humoral and cell-mediated immunological changes
Two years

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
Improvement in stroke symptoms and brain metabolism
Time Frame: Two Years
Possible improvement in stroke symptoms will be determined by a variety of neurological assessments: European Stroke Scale, NIH Stroke Scale, Modified Rankin Score, and Fugl-Meyer assessment. Possible improvement in brain metabolism will be assessed using FDG-PET scans.
