NCT ID: NCT05532943

Last Updated: 2025-08-07

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 41 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2023-09-08
• Study Completion Date: 2028-10-31

Brief Summary

This study is to identify the safety and efficacy of repeat IV(Intravenous) and IT(Intrathecal) administrations of UMSC01 in patients with MS. While anti-inflammatory drugs are routinely used for the treatment of MS by inhibiting immune responses, their effects on axon remyelination or neuroregeneration are limited. The combined systemic delivery of UCMSCs via intravenous injection and local administration of the cells by IT was to have safety and therapeutic efficacy for patients with MS.

Detailed Description

There is single arm in Phase I part: 6 patients will be enrolled sequentially for safety considerations. The patient will receive UMSC01 via IV followed by IT at day 28 as described in above. After all patients in Phase I complete the safety assessment by SMC without any major safety issue 4 weeks after the last UMSC01 administration, the Phase IIa part will be initiated. There are 2 arms in Phase IIa part: Sham-controlled with conventional treatment control and administration of UMSC01 with conventional treatment.

Conditions

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

UMSC01

UMSC01 cells mixed with normal saline will be administered to patients after the onset of diagnosis of multiple sclerosis.

Group Type: EXPERIMENTAL

Allogeneic umbilical cord mesenchymal stem cells

Intervention Type: BIOLOGICAL

UMSC01 cells will be IV infusion followed by IT infusion with 12 months of follow up after treatment.

Placebo

For IV administration, normal saline will be administered to patients after the onset of diagnosis of multiple sclerosis. For IT administration, sham puncture procedure will partially penetrate without reaching subarachnoid space, and no spinal fluid will be drawn.

Group Type: SHAM_COMPARATOR

Control group

Intervention Type: BIOLOGICAL

Normal saline will be IV infusion followed by sham-IT infusion with 12 months of follow up after treatment.

4. Patients who are unable to undergo Brain MRI examination for any reason.

5. Patients who have medical history or current clinically active malignant tumor, peripheral neuropathy, myopathy or other clinically significant neurological diseases that will confound the evaluation of this study.

6. Patients who have immuno-compromised condition or is with known clinically significantly autoimmune conditions other than MS or is receiving immunosuppressive treatments other than MS treatment within 6 months.

7. With active infection that required systemic treatment

8. Patients who are participating in other clinical trials with an investigational product within 1 month.

9. Patients who were treated with cytotoxic medications during the last 1 month prior to the infusion.
