Evaluate the Safety and Efficacy of Allogeneic Umbilical Cord Mesenchymal Stem Cells in Patients With Multiple Sclerosis (UMSC01)

A Seamless Phase I/IIa Clinical Study to Evaluate the Safety and Efficacy of Allogeneic Umbilical Cord Mesenchymal Stem Cells in Patients With Multiple Sclerosis

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.

Study Overview

• Status: Recruiting
• Conditions: Multiple Sclerosis
• Intervention / Treatment: Biological: Allogeneic umbilical cord mesenchymal stem cells; Biological: Control group

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: UMSC01; UMSC01 cells mixed with normal saline will be administered to patients after the onset of diagnosis of multiple sclerosis.	Biological: Allogeneic umbilical cord mesenchymal stem cells; UMSC01 cells will be IV infusion followed by IT infusion with 12 months of follow up after treatment.
Sham Comparator: 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.	Biological: Control group; Normal saline will be IV infusion followed by sham-IT infusion with 12 months of follow up after treatment.
