Response to the SHINGRIX Varicella Zoster Virus (VZV) Vaccine in Chronic Lymphocytic Leukemia (CLL) and CLL Treated With Bruton's Tyrosine Kinase Inhibitor (BTK-I)

Overview

Background: People who have cancer tend to get sick more often. This is in part because of the cancer treatments they get. Because of this, they may get shingles. Scientists had thought people with chronic lymphocytic leukemia (CLL) should not get the shingles vaccine. Now there is a new shingles vaccine that is not live and cannot cause shingles. The new shingles vaccine may protect people with weak immune systems from getting shingles. This is currently shown to be safe to give people 50 years and older to prevent shingles. Researchers want to test how safe the vaccine is and how it works in people with CLL. Objective: To learn how a new shingles vaccine works in people who have chronic lymphocytic leukemia or small lymphocytic lymphoma (SLL). Eligibility: Adults ages 18 years and older with CLL or SLL who are not being treated for CLL or who are getting certain treatments. Design: Participants will be screened with a chart review or through another protocol. Visit 1 At visit 1, participants may have a pregnancy test, blood test, or physical exam. Pregnant participants cannot be in the study. Eligible participants will get the shingles vaccine as an injection. Participants will receive a diary and write down any symptoms they have for 7 days after the vaccines. Visit 2 Visit 2 will be 3 months later. Participants will have blood taken and get another dose of the vaccine. Participants will receive a diary and write down any symptoms they have for 7 days after the vaccines. Visit 3 Visit 3 will be 3 months after visit 2. Participants will have blood taken. Participants may be able to get an additional vaccine the same day as the shingles vaccine.

This study aims to determine the efficacy of the SHINGRIX varicella zoster virus (VZV) vaccine in chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) patients that are treatment naive or receiving Bruton s-tyrosine kinase inhibitor (BTK-I). (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 or SLL * Cohort 1: Treatment naive CLL or SLL patients * Cohort 2: Subjects must be receiving ibrutinib for at least 6 months prior to administration of the first vaccine dose * Cohort 3: Subjects must be receiving acalabrutinib for at least 6 months prior to administration of the first vaccine dose * Age 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 SHINGRIX vaccine efficacy in patients who are treatment naive or receiving BTK-I therapy. A series of 2 doses of SHINGRIX will be given at 0- and 3- month schedule by intramuscular injection. Subjects will be followed for 6 months and receive assessment of serologic response 6 months after the first vaccine dose administration. Study Objectives: Primary Objective: a)Determine the serologic response against VZV after completing the SHINGRIX (RZV) 2- dose vaccine series in the following populations: * CLL patients that are treatment naive (n=54) * CLL patients receiving treatment with ibrutinib (n=27) * CLL patients receiving treatment with acalabrutinib (n=27) Secondary Objective: a) Determine the safety and tolerability of the SHINGRIX vaccine among CLL patients who are treatment naive or receiving BTK-Is (ibrutinib or acalabrutinib).
