About this study

Official title: A Single-arm, Multi-center, Open-label Proof of Concept Safety and Efficacy Study of FCR001 Cell-based Therapy in Adults With Rapidly Progressive Diffuse Cutaneous Systemic Sclerosis at Risk for Organ Failure

This is a multicenter, open-label study to evaluate the safety and tolerability and explore the efficacy of FCR001 cell therapy in adults with rapidly progressive Diffuse Cutaneous Systemic Sclerosis (dcSSc) at risk for organ failure.

Read the detailed description

The purpose of this multicenter, single-arm study is to evaluate the safety and tolerability and explore the efficacy of FCR001 cell therapy in adults with rapidly progressive dcSSc at risk for organ failure. It consists of 2 years of treatment and 3 years of follow-up, with the primary analysis performed at 24 months.

FCR001 is a cell therapy product that is administered by intravenous (IV) infusion, following nonmyeloablative (NMA) conditioning. It consists of mobilized peripheral blood cells, facilitating cells, and αβ T cells. This therapy is designed to induce donor-specific tolerance by establishing sustained chimerism and to protect against graft versus host disease (GvHD), the major impediment for advancing allogeneic hematopoietic stem cell therapy (HSCT) as a potential therapy in patients.

What is being measured

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

  1. Incidence of recipient adverse events (AEs)

    Measured: From day before infusion to 60 months

  2. Incidence of recipient serious adverse events (SAEs)

    Measured: From day before infusion to 60 months

  3. Occurrence of Graft versus Host Disease (GvHD)

    Measured: From infusion to 60 months

  4. Time to neutrophil recovery

    Measured: From infusion to 28 days

  5. Time to platelet recovery

    Measured: From infusion to 28 days

Secondary outcomes (4)

  1. Percent donor whole blood chimerism

    Measured: From infusion to 60 months

  2. Percentage of donor T-cell chimerism

    Measured: From infusion to 60 months

  3. Incidence of donor AEs

    Measured: From donation to 12 months

  4. Incidence of donor SAEs

    Measured: From donation to 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing FCR001 in people with Diffuse Cutaneous Systemic Sclerosis, run by Talaris Therapeutics Inc. 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 19 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 12 Oct 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Incidence of recipient adverse events (AEs) (time frame: From day before infusion to 60 months). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05098145.

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 12 Oct 2023; AzTrials last refreshed its copy on 8 Nov 2026.
