Trial summary

This study investigates whether donors with previous exposure to COVID-19 can pass their immunity by hematopoietic (blood) stem cell transplant (HCT) donation to patients that have not been exposed. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus that causes the COVID19 infection. Read more about this study

About this study

Official title: Observational Study of SARS-CoV-2 Donor-Recipient Immunity Transfer

This study investigates whether donors with previous exposure to COVID-19 can pass their immunity by hematopoietic (blood) stem cell transplant (HCT) donation to patients that have not been exposed. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus that causes the COVID19 infection. This study may provide critical information for medical decision-making and possible immunotherapy interventions in immunocompromised transplant recipients, who are at high risk for COVID19 severe illness.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To establish the possibility of anti-SARS-CoV-2 adaptive immunity transfer from matched related (MRD) or unrelated (MUD) HCT donor to HCT recipient.

SECONDARY OBJECTIVES:

  1. To explore anti-SARS-CoV-2 adaptive immunity transfer in the haploidentical (haplo) HCT setting.

II. To assess the prevalence and change over time of SARS-CoV-2 seropositive donors among all consented donors.

OUTLINE:

DONORS: Prior to HCT, sibling donors (MRD and haplo) undergo a nasopharyngeal swab per standard of care for SARS-Cov-2 testing. For MUD donors, initial testing may consist of a questionnaire. All donors undergo collection of blood and saliva at the time of granulocyte-colony stimulating factor (G-CSF). Donors' medical charts are also reviewed.

RECIPIENTS: Patients undergo a nasopharyngeal swab for SARS-Cov-2 testing at 30, 60, 90, 120 days post-HCT, and afterwards as deemed necessary by the treating physician. Patients also undergo the collection of blood and saliva specimens at days 30, 60, 90, 120, 150, and 180 post-HCT. Recipients' medical charts are also reviewed.

What is being measured

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

  1. Severe acute respiratory syndrome (SARS)-Coronavirus 2 (CoV-2) Spike protein (S)-specific IgG concentration and T cell levels

    Testing for SARS-CoV-2 antibodies will be performed on serum samples using in house developed enzyme-linked immunosorbent assay (ELISA). The qualitative assays will be developed to investigate Spike subunit 1 (S1)-specific antibodies of the IgG, IgM and IgA subclasses in serum and saliva samples. All SARS-Cov-2 seropositive donor-HCT recipient pairs patients will undergo cellular immunogenicity evaluations using flow cytometry. The data analysis for estimating the effect of donor immunity transfer on functional cellular immunity through time will be exploratory in nature and will focus on graphical display and summary statistics. Longitudinal levels of T cells specific for SARS-CoV-2 S will be measured as a correlate of immunity transfer efficiency.

    Measured: Up to 180 days post-hematopoietic stem cell transplant (HCT)

  2. SARS-CoV-2 nucleocapsid protein (N) -specific IgG concentration and T cell levels

    Testing for SARS-CoV-2 antibodies will be performed on serum samples using in house developed ELISA. The qualitative assays will be developed to investigate nucleocapsid (N)-specific antibodies of the IgG, IgM and IgA subclasses in serum and saliva samples. All SARS-Cov-2 seropositive donor-HCT recipient pairs patients will undergo cellular immunogenicity evaluations using flow cytometry. The data analysis for estimating the effect of donor immunity transfer on functional cellular immunity through time will be exploratory in nature and will focus on graphical display and summary statistics. Longitudinal levels of T cells specific for SARS-CoV-2 N antigens will be measured as a correlate of immunity transfer efficiency.

    Measured: Up to 180 days post-HCT

  3. SARS-CoV-2 neutralizing antibodies

    Evaluation of SARS-CoV-2 neutralizing antibody titers in serum samples will be performed using SARS-CoV-2 lentiviral-pseudovirus based on published protocols. Spike incorporation into the pseudovirus will be verified and quantified by western blot using Spike-specific antibodies (Sino Biological) and by ELISA using Spike Detection kit (Sino Biological), respectively.

    Measured: Up to 180 days post-HCT

Secondary outcomes (1)
  1. SARS-CoV-2 IgA concentration

    Testing for SARS-CoV-2 antibodies will be performed on serum samples using in house developed ELISA.

    Measured: Up to 180 days post-HCT

Who may be eligible to take part?

The sponsor lists 16 inclusion and 0 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: finished, as of the sponsor's last update on 8 Apr 2024. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Severe acute respiratory syndrome (SARS)-Coronavirus 2 (CoV-2) Spike protein (S)-specific IgG concentration and T cell levels (time frame: Up to 180 days post-hematopoietic stem cell transplant (HCT)). The study lists 3 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 NCT04666025, which also lists 2 linked publications.

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.
