About this study

Official title: Acceptance and Effectiveness of SARS-COV-2 Vaccination in Systemic Sclerosis Patients Treated by Autologous Hematopoietic Stem Cell Transplantation

On December 27th 2020, the implementation of SARS-CoV-2 vaccination in France first became available amongst all immunosuppressed patients at very high risk of severe Coronavirus Disease (COVID-19) infection, specifically for Hematopoietic Stem Cell Transplant recipients or other fragile immunosuppressed patients.

Systemic sclerosis (SSc) is an autoimmune disease characterized by dysregulation of the immune system, vascular damage and progressive fibrosis of the skin and internal organs (heart, lung and kidney) which may lead to severe comorbidities and SSc-related mortality. In severe rapidly progressive SSc, we and others demonstrated that autologous hematopoietic stem cell transplantation (AHSCT) is the only treatment so far allowing improvement in overall and event free survival up to 7 years after AHSCT.

As soon as vaccines were available on January 1st, 2021 and following the French Haute Autorité de Santé (HAS) and Société Francophone de Greffe de Moelle et de Thérapie Cellulaire (SFGM-TC) good clinical practices (GCP) guidelines, the ad hoc COVID19 vaccinations were proposed to all SSc patients in France, including those previously treated by AHSCT and followed at Maladies Auto Immunes et Thérapie Cellulaire (MATHEC) Center of Reference for stem cell therapy at St-Louis hospital. In July 2021, the Autoimmune Diseases Working Party (ADWP) and the European society for Blood and Marrow Transplantation (EBMT) guidelines recommended vaccination against SARS-CoV2 as early as 3 months after HSCT for autoimmune diseases.

Only one Israeli study so far has analyzed the efficacy of SARS-CoV-2 vaccination after autologous HSCT (AHSCT) in SSc patients..

We therefore designed the present case control study retrospective study to assess the acceptance and effectiveness of this vaccination program in SSc patients treated by AHSCT as compared to other fragile SSc individuals.

The Primary objective is to evaluate the effectiveness of implementing the anti-SARS-CoV2 vaccination program according to the French GCP for COVID-19 prophylaxis in SSc fragile patients, in terms of risk of asymptomatic or symptomatic COVID-19 infection, among SSc patients treated by AHSCT compared to 1:1 matched non transplant SSc controls.

What is being measured

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

  1. Cumulative incidence of asymptomatic or symptomatic COVID-19 infection after AHSCT as compared to non AHSCT SSc patients.

    Asymptomatic COVID-19 are defined by positive Polymerase Chain Polymerase (PCR) on routine testing (contact case or fortuitous discovery). Symptomatic COVID-19 patients are defined by positive PCR test and clinical symptoms related to COVID-19 infection.

    Measured: Up to 18 months

Secondary outcomes (6)
  1. Proportion of SSc patients, previously treated by AHSCT and in non-transplant controls, who refused vaccination during the study period

    Measured: Up to 18 months

  2. Cumulative incidence of symptomatic COVID-19 infection in SSc patients previously treated by AHSCT and in non-transplant controls

    Measured: Up to 18 months

  3. Time of onset of first COVID-19 infection (symptomatic or asymptomatic) diagnosed during the study period after completing at least 2 vaccines injections in SSc patients previously treated by AHSCT and in non-transplant controls

    Measured: Up to 18 months

  4. Severity of symptomatic COVID-19

    It is assessed and classified according to the care needed for each patient: asymptomatic; mild=ambulatory; moderate=hospitalised out of Intensive Care Unit (ICU); and severe=ICU or deceased

    Measured: Up to 18 months

  5. Proportion of SSc patients with at least 1 grade≥3 adverse event after COVID19 vaccination

    It is assessed according to Common Terminology Criteria for Adverse Events (CTC-AE v5.0)

    Measured: Up to 18 months

  6. Humoral response in SSc patients treated by AHSCT and in controls after messenger RiboNucleic Acid (mRNA) vaccine against SARS-CoV

    It is assessed as positive or negative, according to the presence of SARS-CoV-2 S1/S2 Immunoglobulin G (IgG) antibodies on serological test performed after the second vaccine dose or after 1 vaccine and one COVID-19 infection. Patients were considered positive or negative for being able to mount a humoral response according to national GCP guidelines (last update March 2022).The threshold for a positive immunogenic response was defined by local laboratory standards according to the manufacturer's instructions for cut-off values.

    Measured: Up to 18 months

Questions about this trial

What is this clinical trial studying?

An observational study of Systemic Sclerosis and SARS-CoV 2 Vaccination, run by Assistance Publique - Hôpitaux de Paris.

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 4 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 25 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

Contact Dominique Farge, Pr (+33142499768, dominique.farge-bancel@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cumulative incidence of asymptomatic or symptomatic COVID-19 infection after AHSCT as compared to non AHSCT SSc patients. (time frame: Up to 18 months). 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 25 Jul 2023.
