People with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) tend to get infections more easily. This is because their immune systems are weakened. Hepatitis B is a virus that can be transmitted when body fluids from an infected person enter the body of an uninfected person. This virus can be dangerous for people with leukemia and lymphoma. HEPLISAV-B is a new hepatitis B vaccine. Researchers want to see if it can protect people with CLL/SLL from getting hepatitis B.
To learn how HEPLISAV-B works in people who have CLL or SLL.
Adults 18 years and older with CLL (or SLL). They must be getting no treatment for their CLL, or getting ibrutinib or acalabrutinib for it.
This study lasts 6 months from the date of first vaccination.
Participants may be screened with:
Participants will get blood drawn and the study vaccine. It will be given as an injection. If they get any symptoms within 7 days of the vaccine, they will write them in a diary.
After 3 months, participants will come back to the NIH to get another blood draw and the second vaccine dose.
Participants will return 3 months after the second vaccine dose was given. They will have blood drawn.

This study aims to determine the HEPLISAV-B hepatitis B vaccine efficacy in chronic lymphocytic leukemia (CLL) patients that are treatment naive or receiving Bruton s-tyrosine kinase inhibitor (BTK-I) therapy.
Key Eligibility Criteria:
- Diagnosis of CLL
- Cohort 1: Treatment naive CLL patients
- Cohort 2: Subjects must be receiving ibrutinib monotherapy for at least 6 months prior to administration of the first vaccine dose
- Cohort 3: Subjects must be receiving acalabrutinib monotherapy for at least 6 months prior to administration of the first vaccine dose
- No known active or past hepatitis B infection
- History of prior hepatitis B virus vaccination (approved or investigational)
- Age greater greater than or equal to 18 years.
- ECOG performance status of 0-1
Patients with CLL will enroll on the study for the purpose of determining the HEPLISAV-B vaccine efficacy in patients who are treatment naive ore receiving BTK-I therapy. A series of 2 doses of HEPLISAV-B will be given on a 0- and 3- month schedule by intramuscular injection. Subjects will be followed at regular intervals and receive serologic response assessment following completion of the HEPLISAV-B vaccine series (6 months after the first vaccine
a) Determine the rate of hepatitis B seroprotective titer achievement (anti-HBs greater than or equal to 10mIU/mL) following completion of the HEPLISAV-B 2-dose vaccine series (6 months after the first vaccine administration) in the following populations:
- CLL patients who are treatment naive (n=54)
- CLL patients receiving treatment with ibrutinib (n=27)
- CLL patients receiving treatment with acalabrutinib (n=27)
a) Determine the safety and tolerability of the HEPLISAV-B vaccine among CLL patients who are treatment naive or receiving BTK-Is (ibrutinib or acalabrutinib).

Patients with CLL
HEPLISAV-B (Hepatitis B Vaccine [Recombinant ], adjuvanted) vaccine - A series of 2 doses (0.5 ml each) will be given on a 0- and 3- month schedule via intramuscular injection.
- HEPLISAV-B seroprotective titer (anti-HBs 10mIU/mL) [ Time Frame: 3 months after the first vaccine administration ]Determine the rate of hepatitis B seroprotective titer achievement (anti-HBs 10mIU/mL) following completion of the HEPLISAV-B 2-dose vaccine series (3 months after the first vaccine administration)
- Safety and tolerability of the HEPLISAV-B vaccine among CLL patients who are treatment naive or receiving BTK-Is (ibrutinib or acalabrutinib) [ Time Frame: 3 months after the first vaccine administration ]Determine the safety and tolerability of the HEPLISAV-B vaccine among CLL patients who are treatment naive or receiving BTK-Is (ibrutinib or acalabrutinib).
