Study Details

Study Description

Brief Summary

This phase II trial compares the effect of initial vaccination (PCV13 followed by PSV23) with yearly vaccinations of PSV23 to the standard 5 year vaccination in patients with chronic lymphocytic leukemia. At present chronic lymphocytic leukemia patients are poorly protected by anti-pneumococcal vaccination. Current vaccination schedule for chronic lymphocytic leukemia patients is based on general recommendations in immunocompromised patients (initial vaccination with PCV13 followed by one dose of PSV23 after an interval of two months, followed by revaccination at 5 years). Giving patients frequent immunization as compared to 5 year immunization may result in higher protective titers in patients.

Condition or Disease Intervention/Treatment Phase
  • Biological: Pneumococcal 13-valent Conjugate Vaccine
  • Biological: Pneumococcal Polyvalent Vaccine
Phase 2

Detailed Description

PRIMARY OBJECTIVE:
  1. Proportion of patients with anti-pneumococcal immunogenicity following early revaccination (1 year) at 2 years (Serotype to be measured are 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A 19 F and 23F using the enzyme-linked immunosorbent assay [ELISA] method).
SECONDARY OBJECTIVES:
  1. Number of patients with anti-pneumococcal immunogenicity at 5 years. II. Number of patients with local and/or general reaction at months 1, 3 as self-reported.

  2. Number of pneumococcal infections.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients receive pneumococcal 13-valent conjugate vaccine (PCV13) intramuscularly (IM) at week 1 and pneumococcal polyvalent vaccine (PSV23) IM at week 8. Patients then receive PSV23 IM booster at years 1, 2, 3, 4 and 5.

ARM B: Patients receive PCV13 IM at week 1 and PSV23 IM at week 8. Patients then receive PSV23 IM booster at year 5.

    Secondary Outcome Measures

    1. Proportion of patients with anti-pneumococcal immunogenicity [At 5 years]

    2. Proportion of patients with local and/or general reaction [At 1 and 3 months]

    3. Number of pneumococcal infections [At 5 years]

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:

    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:
    • Men and women >= 18 years of age

    • Patients must have histologically identified chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) as defined by the World Health Organization (WHO) classification of hematopoietic neoplasms

    • Treatment naive CLL/SLL; No prior therapy for CLL/SLL, including chemotherapy and/or radiotherapy is allowed

    • Estimated life expectancy of greater than 24 months

    Exclusion Criteria:
    • Patients with neutropenic (granulocyte [PMN]s < 500 cells/mm^3) or having received rituximab within 6 months

    • Patients with fever (temperature > 38 degrees Celsius [C]) within 1 week

    • History of allergic reactions attributable to compounds of similar chemical or biologic composition to any component of pneumococcal vaccines
