Study groups in NCT05007860
Study groupRoleWhat they receive
No active therapyAge ≥18 years and CLL/SLL (WHO criteria). We excluded patients with known HIV or primary immune deficiency disorder, known active progression of CLL/SLL, active therapy, treating physician intent to initiate CLL/SLL therapy within ≤2 months, prior cytotoxic chemotherapy within ≤1 year, CD20 monoclonal Ab within ≤6 months, or any prior bendamustine or fludarabine. We excluded patients who received PCV13 within ≤2 years, or within 2-5 years with nonprotective titers for ≥50% of PCV13-specific S. pneumonia IgG titers.
Receives: Biological: PCV13 vaccine and any of the FDA-approved COVID-19 vaccine products (BNT162b2, mRNA-1273, or Ad26.COV2.S) based on local availability.
BTK inhibitor therapy (continued)Age ≥18 years, CLL/SLL (WHO criteria), and active therapy with a BTK inhibitor which is continued through vaccination. We excluded patients with known HIV or primary immune deficiency disorder, known active progression of CLL/SLL, prior cytotoxic chemotherapy within ≤1 year, CD20 monoclonal Ab within ≤6 months, or any prior bendamustine or fludarabine. We excluded patients who received PCV13 within ≤2 years, or within 2-5 years with nonprotective titers for ≥50% of PCV13-specific S. pneumonia IgG titers.
Receives: Biological: PCV13 vaccine and any of the FDA-approved COVID-19 vaccine products (BNT162b2, mRNA-1273, or Ad26.COV2.S) based on local availability.
BTK inhibitor therapy (interrupted)Age ≥18 years, CLL/SLL (WHO criteria), and active therapy with a BTK inhibitor which is interrupted at time of vaccination. We excluded patients with known HIV or primary immune deficiency disorder, known active progression of CLL/SLL, prior cytotoxic chemotherapy within ≤1 year, CD20 monoclonal Ab within ≤6 months, or any prior bendamustine or fludarabine. We excluded patients who received PCV13 within ≤2 years, or within 2-5 years with nonprotective titers for ≥50% of PCV13-specific S. pneumonia IgG titers.
Receives: Biological: PCV13 vaccine and any of the FDA-approved COVID-19 vaccine products (BNT162b2, mRNA-1273, or Ad26.COV2.S) based on local availability.

What is being measured

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

  1. Effective immune response (EIR) to PCV13 vaccination

    EIR is defined as a >2-fold increase or conversion from a nonprotective to a protective titer for >50% of specific S. pneumonia IgG titers (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F) vs baseline.

    Measured: 35 days (+/- 14 days) after vaccination

  2. Effective immune response (EIR) to COVID19 vaccination

    EIR is defined as a >4-fold increase from baseline, or seroconversion defined as change from negative to within the measuring interval, for specific SARS-CoV-2 antibody titers (spike protein). For patients without pre-COVID-19 vaccination.

    serology, a negative post-COVID-19 vaccination nucleocapsid antibody titer will be used as a surrogate for no prior infection and in this case a post-COVID-19 vaccination spike antibody titer within the measuring interval will be interpreted as an EIR.

    Measured: 35 days (+/- 14 days) after vaccination

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma, run by Massachusetts General Hospital 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 10 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 7 Jul 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 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?

Effective immune response (EIR) to PCV13 vaccination (time frame: 35 days (+/- 14 days) after vaccination). The study lists 2 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 NCT05007860, which also lists 1 linked publication.

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 7 Jul 2023.
