Outcome Measures

Primary Outcomes (1)

  • Change of Functional Independence Measure

    The difference in the FIM (Functional Independence Measure)score between the three groups at baseline, 90 days, and 180 days was confirmed by comparing differences in scores (total score\[18\~126\], motor score\[13\~90\], and cognition score\[5\~35\]. The total score is the sum of the motor score and the cognition score. The higher scores represent a better outcome )

    baseline - 3 months - 6 months

Secondary Outcomes (11)

  • Change of Medical research council

    baseline - 3 months - 6 months

  • Change of National Institutes of Health Stroke Scale

    baseline - 3 months - 6 months

  • Change of Manual Function Test

    baseline - 3 months - 6 months

  • Change of Fugl-Meyer Assessment

    baseline - 3 months - 6 months

  • Change of Berg Balance Scale

    baseline - 3 months - 6 months

  • +6 more secondary outcomes

Study Arms (3)

UCB infusion and EPO injection group

EXPERIMENTAL

Take immunosuppressant agents for 1 week. Umbilical cord blood is administered in the treatment room. Afterward, the venous erythropoietin agent injects into the peripheral vein 5 times a total of 5 times a week.

Drug: Placebo umbilical cord blood infusionDrug: Placebo erythropoietin injectionProcedure: Active rehabilitation

UCB infusion and placebo EPO injection group

EXPERIMENTAL

Take immunosuppressant agents for 1 week. Umbilical cord blood is administered in the treatment room. Afterward, the venous erythropoietin placebo injects into the peripheral vein 5 times a total of 5 times a week.

PLACEBO COMPARATOR

Take immunosuppressant placebo for 1 week with the same schedule as the experimental group. As in the experimental group, placebo umbilical cord blood is administered in the treatment room and stay in the treatment room for the same time. Afterward, the venous erythropoietin placebo injects into the peripheral vein 5 times a total of 5 times a week. Other inspection schedules proceed with other groups.

Interventions

The umbilical cord blood is donated umbilical cord blood which is stored in the cord blood bank donated by Cha Hospital. The total number of nuclear cells should be at least 2 x 10 7 / kg, and at least three out of six of the six human leukocyte antigens (HLA-A, B, DR) should be selected. The cord blood that matches ABO and Rh blood type is preferentially used. Umbilical cord blood infusion is administered intravenously and is performed at the stem cell clinical trial center. The procedure is performed by the doctor who is enrolled in this study. Monitor pulse and oxygen saturation during the procedure.

Also known as: UCB
Placebo UCB infusion and placebo EPO injection groupUCB infusion and placebo EPO injection group

Recombinant human erythropoietin is used and is administered intravenously at a maximum of 5 times at a rate of 500 IU / kg 2 times/week after cord blood peripheral blood infusion, calculated as the dose per body weight. Or subcutaneous administration if intravenous administration is not possible. Store in a sealed container at 2-8 °C in the refrigerator before dosing. Erythropoietin injection is performed at the stem cell clinical trial center. The procedure is performed by the doctor who is enrolled in this study. Monitor pulse and oxygen saturation during the procedure.

Also known as: EPO
Placebo UCB infusion and placebo EPO injection group

Placebo umbilical cord blood infusion is administered intravenously and is performed at the stem cell clinical trial center. The procedure is performed by the doctor who is enrolled in this study. Monitor pulse and oxygen saturation during the procedure.

Also known as: pUCB
UCB infusion and EPO injection group

Placebo erythropoietin injection is performed at the stem cell clinical trial center. The procedure is performed by the doctor who is enrolled in this study. Monitor pulse and oxygen saturation during the procedure.
