Summary

This trial is testing whether an initial vaccination, followed by yearly vaccinations, is more effective than the standard 5 year vaccination schedule for patients with chronic lymphocytic leukemia.

Who is the study for?
Adults diagnosed with chronic lymphocytic leukemia or small lymphocytic lymphoma who haven't had previous treatments can join. They should have a life expectancy over 24 months, not be on certain immune system drugs, and must understand the study to give consent. Those with recent chemotherapy, vaccinations, very low lymphocyte counts, severe immune deficiencies, HIV infection or other serious illnesses cannot participate.
What is being tested?
The trial is testing two anti-pneumococcal vaccine schedules in patients with chronic lymphocytic leukemia: one involves initial vaccination followed by yearly shots; the other uses the standard five-year schedule. The goal is to see if more frequent vaccines offer better protection against pneumonia.
What are the potential side effects?
Possible side effects from pneumococcal vaccines include pain at the injection site, fatigue, headache, muscle pain, joint pain and fever. Severe allergic reactions are rare but may occur in some individuals.

Trial Design

3Treatment groups
Experimental Treatment
Active Control
Group I: Arm C (Experimental ARM-Annual Booster)Experimental Treatment2 Interventions
Patients receive PCV 20 IM at week 0 and PSV23 IM at week 8. Titers will be checked 4 weeks after the first dose and at 12 weeks (4 weeks after the second dose). Booster Vaccine: PCV23 booster vaccination dose will be administered yearly for 5 years. Pre-vaccination and post-vaccination (at 4 weeks) titers will be checked each time yearly for 5 years.
Group II: Arm B (Experimental ARM-No Booster)Experimental Treatment2 Interventions
Patients receive PCV 20 IM at week 0 and PSV23 IM at week 8. Titers will be checked 4 weeks after the first dose and at 12 weeks (4 weeks after the second dose). Booster Vaccine: None. Annual titers will be checked for 5 years.
Group III: Arm A (Standard ARM- No Booster)Active Control1 Intervention
Patients receive PCV 20 IM at week 0. Titers will be checked 4 weeks after this dose. Booster Vaccine: None. Titers will be checked at 12 weeks and then yearly for 5 years.
