A "negative"dendritic Cell-based Vaccine for the Treatment of Multiple Sclerosis: a First-in-human Clinical Trial (MS-tolDC)

December 4, 2024 updated by: Zwi Berneman, University Hospital, Antwerp
A first-in-human clinical trial to treat patients with multiple sclerosis by vaccination with tolerogenic dendritic cells (tolDC), generated using Good Manufacturing Practice (GMP) will be conducted. In doing so, the feasibility and safety of administering myelin-derived peptide-pulsed tolDC in patients with MS will be assessed.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

A phase I dose-escalating clinical trial will be conducted in a coordinated and comprehensive manner to determine safety and tolerability, and to enable selection of a suitable dose regimen for phase II trials. The primary objective of the phase I study will be to determine whether tolDC-based therapy is safe and well tolerated and to establish the dose-response, with clinical relapse rates, neurological disability (assessed using various scales) and MRI endpoints, measured over 12 months. Patients will serve as their own controls pre- and post-vaccination. Completion of screening assessments and confirmation of eligibility criteria should take no longer than 6 weeks. First-line treatments will be stopped 6 weeks before baseline at the latest.

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.

Intervention / Treatment

Intervention / Treatment

Experimental: tolerogenic dendritic cells (tolDC)
Each vaccine (5x106, 10x106 , or 15x106cells in 500 µL NaCl 0.9% solution supplemented with 5% human albumin) will be administered through intradermal injection at 5 sites (100 µL/site) in the subclavicular region (5-10 cm from the cervical lymph nodes). Injection sites will alternate between left and right sides.
