Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

No active therapy

Age ≥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.

PCV13 vaccine and any of the FDA-approved COVID-19 vaccine products (BNT162b2, mRNA-1273, or Ad26.COV2.S) based on local availability.

Intervention Type BIOLOGICAL

Vaccines administered per standard of care

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.

Intervention Type BIOLOGICAL

Vaccines administered per standard of care

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Exclusion Criteria

* Age \>18 years.
* Diagnosis of CLL or SLL according to WHO criteria.
* For patients receiving BTK inhibitor (Cohorts 1 and 2):

* Patient must have no history of cytotoxic chemotherapy within 1 year (no prior history of bendamustine or fludarabine is permitted) and no history of CD20 monoclonal antibody within 6 months.
* Patient must have no known clinical or radiographic evidence of CLL progression.
* For patients not on active therapy (Cohort 3):

* Patient must have no history of cytotoxic chemotherapy within 1 year (no prior history of bendamustine or fludarabine is permitted) and no history of CD20 monoclonal antibody within 6 months.
* The treating investigator must have no intention to initiate CLL therapy within 2 months.
* Patients must have not received PCV13 within 2 years. For patients with PCV13 within 5 years, S. pneumonia IgG antibody concentrations must be less than the reference value for at least 50% of S. pneumoniae serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A,19F and 23F. Patients can have received prior PPV23 within any time frame.
* Patient must have no known history of HIV or primary immune deficiency disorder, nor be taking a concurrent immune suppressing medication (e.g. steroids, methotrexate, etc.).
