A Study to Evaluate the Safety, Tolerability, and Exploratory Efficacy of IMS001 in Subjects With Multiple Sclerosis

April 2, 2026 updated by: ImStem Biotechnology

A Phase 1, Dose-Escalating, Open-label Study to Evaluate the Safety, Tolerability, and Exploratory Efficacy of Single Dose of IV IMS001 in Subjects With Multiple Sclerosis and Treatment Failure to Prior Disease Modifying Treatments (DMTs)

This is a Phase 1 study of IMS001, given as a single dose to subjects with Multiple Sclerosis who experience inadequate response and/or intolerability to disease modifying treatments. IMS001 is a human embryonic cell derived (hESC) mesenchymal stem cell (MSC). MSCs have the potential to modulate disease course.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 61 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
