About this study

Official title: Optimal Conditioning Regimen Protocol for Autologous Hematopoietic Stem Cell Transplantation of Relapsing Remitting Multiple Sclerosis

This study is designed to compare two non-myeloablative conditioning regimens (combination of chemotherapy and immune specific proteins against immune cells) for relapsing remitting multiple sclerosis (RRMS). The two conditioning regimens are the most commonly used world wide in clinical practice for the treatment of multiple sclerosis (MS). The first investigational conditioning regimen is cyclophosphamide (chemotherapy) and rATG (rabbit anti-thymocyte globulin, a protein against immune cells). The second investigational conditioning regimen includes the same dose of cyclophosphamide (chemotherapy) and rituximab (a protein against immune cells). Both cyclophosphamide and either rATG or rituximab are given to kill immune cells that are thought to be causing MS, followed by return of one's own previously collected blood stem cells (autologous stem cell transplant) to hasten recovery. The goal of this study is to assess the difference of these treatments in terms of toxicity and efficacy.

Read the detailed description

Autologous hematopoietic stem cell transplantation (HSCT) in patients with active relapsing remitting multiple sclerosis (RRMS) halts disease progression, improves neurologic disability and quality of life, and provides a prolonged drug-free remission. A "position paper" by neurologists and hematologists under the American Society of Transplant and Cellular Therapy (ASTCT) has recommended autologous HSCT as standard of care, clinical evidence available, for treatment-refractory relapsing MS with high risk of future disability. Similarly, the EBMT has recommended the use of HSCT as "standard or care" for patients with highly active RRMS failing at least one DMT. Currently, the optimal conditioning regimen in terms of safety and efficacy is unknown. Herein, we will compare the two most commonly used regimens cyclophosphamide/ATG, or cyclophosphamide/rituximab in terms of safety and efficacy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Durability of remission between two arms

    Defined as the time to first confirmed acute relapse or 5 years after treatment which ever comes first

    Measured: Time to first confirmed acute relapse or 5 years after treatment which ever comes first

Secondary outcomes (1)
  1. Neurologic Disability

    Defined by change in EDSS (Expanded Disability Status Scale, ranges from 0 to 10 with 0 normal and 10 worst)

    Measured: From initiation of study to completion, up until 5 years after treatment

Questions about this trial

What is this clinical trial studying?

A study testing Autologous hematopoietic stem cell transplantation, Cyclophosphamide/ATG and Cyclophosphamide/Rituximab in people with Multiple Sclerosis, Relapsing-Remitting, run by Scripps Health at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 51 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 9 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Durability of remission between two arms (time frame: Time to first confirmed acute relapse or 5 years after treatment which ever comes first). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Nov 2023.
