Condition or disease | Intervention/treatment | Phase |
---|---|---|
Ischemic Stroke | Biological: Umbilical Cord-derived Mesenchymal Stem Cells Drug: Placebo | Phase 2 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 200 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Two different treatment groups; intravenous umbilical cord-derived mesenchymal stem cells or intravenous placebo solution |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
Masking Description: | Treatment and placebo solutions have identical appearance. Protocols will be designed to ensure that the physician evaluating patient safety and efficacy outcome as well as laboratory analysis, will not have access to the randomisation codes. |
Primary Purpose: | Treatment |
Official Title: | Umbilical Cord-derived Mesenchymal Stem Cells for Ischemic Stroke (UMSIS): a Prospective, Double-blinded, Randomized Controlled, Pilot Study |
Actual Study Start Date : | March 15, 2021 |
Estimated Primary Completion Date : | February 1, 2023 |
Estimated Study Completion Date : | October 1, 2023 |

Arm | Intervention/treatment |
---|---|
Experimental: Treatment group
intravenous umbilical cord derived mesenchymal stem cells
|
Biological: Umbilical Cord-derived Mesenchymal Stem Cells
umbilical cord derived mesenchymal stem cells were intravenously injected in a single dose of one hundred million. |
Placebo Comparator: Placebo Comparator
intravenous placebo solution with the same appearance as the treatment group.
|
Drug: Placebo
intravenous placebo solution with the same appearance as the treatment group. |
- Proportion of modified Rankin Scale (mRS) 0-2 [ Time Frame: 90 Days ]the minimum and maximum values of mRS are 0 and 6, respectively; higher mRS mean a worse outcome
- Proportion of modified Rankin Scale (mRS) 0-2 [ Time Frame: 180,360 Days ]the minimum and maximum values of mRS are 0 and 6, respectively; higher mRS mean a worse outcome
- changes in Fugl-Meyer scale [ Time Frame: 90days;180days;360days ]Fugl-Meyer Assessment Scale ranges from 0 to 100.
- changes in Purdue hand function test [ Time Frame: 90days;180days;360days ]The changes of fine motor function were evaluated by Purdue hand function test
- changes in box and block test [ Time Frame: 90days;180days;360days ]The changes of fine motor function were evaluated by box and block test
- Proportion of modified Rankin Scale (mRS) 0-1 [ Time Frame: 90days;180days;360days ]the minimum and maximum values of mRS are 0 and 6, respectively; higher mRS
- changes in the national institutes of health stroke scale (NIHSS) [ Time Frame: 90days;180days;360days ]NIHSS ranges from 0-42, and high NIHSS means bad outcome
- changes in Mini-mental State Examination (MMSE) score [ Time Frame: 90days;180days;360days ]MMSE score ranges from 0 to 30.
- changes in Montreal Cognitive Assessment (MoCA) score [ Time Frame: 90days;180days;360days ]MOCA score ranges from 0 to 30.
- The changes of head images [ Time Frame: 90days;180days;360days ]head images included flair, DTI
- changes in some serum biomarkers [ Time Frame: 90days;180days;360days ]serum biomarkers included CPEC, VEGF, BDNF, MMP-9
- Number of Adverse Events [ Time Frame: 360days ]
