About this study

Official title: Autologous Very Small Embryonic-like Stem Cells(VSELs) for Knee Osteoarthritis

The aim of this study is the safety and efficacy of autologous very small embryonic-like stem cells(VSELs) to knee osteoarthritis.

Read the detailed description

VSELs come from the patient's peripheral blood, and will be injected in the most painful knee, or the worse knee on physical examination. Then follow-up the knee pain and imaging changes at 6 months and 1 year after treatment.

Being tested
very small embryonic-like stem cell
Medical subject headings
Osteoarthritis, Knee

What participants receive

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

  • very small embryonic-like stem cellBiological

    Also called VSEL

    Mononuclear cells were collected from peripheral blood of each patient using a machine, VSELs were isolated, and each group was injected according to different numbers after activation

Study groups in NCT03975101
Study groupRoleWhat they receive
VSEL MaxExperimentalA mean volume of 5.5 mL platelet-rich plasma containing approximately 120,000 cells were prepared and injected into the selected knee of the patient
Receives: Biological: very small embryonic-like stem cell
VSEL MediumExperimentalA mean volume of 5.5 mL platelet-rich plasma containing approximately 90,000 cells were prepared and injected into the selected knee of the patient
Receives: Biological: very small embryonic-like stem cell
VSEL MiniExperimentalA mean volume of 5.5 mL platelet-rich plasma containing approximately 60,000 cells were prepared and injected into the selected knee of the patient
Receives: Biological: very small embryonic-like stem cell
ControlNo interventionA mean volume of 5.5 mL platelet-rich plasma containing no VSELs injected into the selected knee of the patient

What is being measured

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

  1. Change of knee pain score

    Pain assessment by visual analogue score (VAS). 0 point: no pain; 1-3 points: there is a slight pain that can be tolerated; 4-6 points: the patient has pain and affects sleep, and can still bear it; 7-10 points: the patient has progressively strong pain, pain is unbearable, affecting appetite and sleep

    Measured: 2-4 weeks after injection

Secondary outcomes (4)
  1. Change of knee pain score

    Pain assessment by visual analogue score (VAS). 0 point: no pain; 1-3 points: there is a slight pain that can be tolerated; 4-6 points: the patient has pain and affects sleep, and can still bear it; 7-10 points: the patient has progressively strong pain, pain is unbearable, affecting appetite and sleep

    Measured: 6 months after injection

  2. Imaging changes in the knee joint

    Magnetic resonance image (MRI) examination of the smoothness of the knee joint surface, ligament, soft tissue and meniscus damage

    Measured: 6 months after injection

  3. Change of knee pain score

    Pain assessment by visual analogue score (VAS). 0 point: no pain; 1-3 points: there is a slight pain that can be tolerated; 4-6 points: the patient has pain and affects sleep, and can still bear it; 7-10 points: the patient has progressively strong pain, pain is unbearable, affecting appetite and sleep

    Measured: 12 months after injection

  4. Imaging changes in the knee joint

    MRI examination of the smoothness of the knee joint surface, ligament, soft tissue and meniscus damage

    Measured: 12 months after injection

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing very small embryonic-like stem cell in people with Stem Cell Transplant Complications and Knee Osteoarthritis, run by Fuda Cancer Hospital, Guangzhou at 1 site in China.

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 4 inclusion and 2 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: withdrawn, as of the sponsor's last update on 19 Oct 2020. 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 China. 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 combined 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.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Change of knee pain score (time frame: 2-4 weeks after injection). 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 19 Oct 2020.
