简要总结
Background:
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.
Objective:
To learn how HEPLISAV-B works in people who have CLL or SLL.
Eligibility:
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.
Design:
This study lasts 6 months from the date of first vaccination.
Participants may be screened with:
Physical exam
Blood tests
Pregnancy test
Visit 1
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.
Visit 2
After 3 months, participants will come back to the NIH to get another blood draw and the second vaccine dose.
Visit 3
Participants will return 3 months after the second vaccine dose was given. They will have blood drawn.
详细描述
This study aims to determine the HEPLISAV-B hepatitis B vaccine efficacy in chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) lymphocytic patients that are treatment naive or receiving Bruton s-tyrosine kinase inhibitor (BTK-I) therapy. (Note: Since CLL and SLL are considered the same disease, CLL/SLL will be referred to as CLL hereafter, unless otherwise specified).
Key Eligibility Criteria:
- Diagnosis of CLL
- Cohort 1: Treatment naive CLL or SLL 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
- No 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
Design:
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

结局指标
主要结局
Number of Participants With HEPLISAV-B Seroprotective Titer (Anti-HBs 10mIU/mL)
时间窗: 6 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 (6 months after the first vaccine administration) among chronic lymphocytic leukemia (CLL) patients who are treatment naïve or receiving Bruton Tyrosine Kinase (BTK) inhibitors (Ibrutinib or Acalabrutinib).
次要结局
- Number of Participants That Experienced Serious Adverse Events Following HEPLISAV-B Vaccine Among CLL Patients(6 months after the first vaccine administration)
- Number of Participants That Did Not Complete Study Due to Intolerance of the HEPLISAV-B Vaccine Among CLL Patients.(6 months after the first vaccine administration)
