|Condition or disease||Intervention/treatment||Phase|
|Leukemia||Drug: Sargramostim (GM-CSF) Biological: Pneumococcal Vaccine||Phase 2|
Sargramostim (also commonly called granulocyte macrophage colony stimulating factor - GM-CSF) is a medication used to stimulate the bone marrow production of white blood cells before a stem cell transplant, after chemotherapy or after a bone marrow transplant. Pneumococcal vaccine is a medication used to prevent infections caused by a bacteria called Streptococcus pneumoniae.
If you have not had a gammaglobulins test (a test to measure immunity against certain infectious diseases) measured within three months before the study begins, then this blood test will be done before you receive any study medications.
Women who are able to have children must have a negative urine pregnancy test before starting treatment.
After consenting to this study, you will be randomly assigned (as in the toss of a coin) to receive treatment with sargramostim in addition to the pneumococcal vaccine or to receive pneumococcal vaccine alone (Prevnar).
- If you are randomized to vaccine plus sargramostim group, you will receive an injection of sargramostim at the same time you receive the pneumococcal vaccine.
- If you are randomized to the vaccine alone group, you will receive the pneumococcal vaccine on the first day.
Blood tests will be performed on the day of the pneumococcal vaccination, and 4 weeks, 12 weeks and 24 weeks after vaccination. Each of the blood tests will require about 4 teaspoons of blood. These blood tests will measure your immunity to pneumococcal infection.
If after 6 months of your first vaccination your body is not able to show immunity to pneumococcal infection, you will receive a second dose either pneumococcal vaccine plus sargramostim or pneumococcal vaccine alone. Your immunity will be checked again at 4 weeks, 12 weeks, and 24 weeks after this second dose. Only 4 teaspoon of blood will be required for the tests.
You may be removed from the study if you have a severe allergic reaction to the sargramostim and/or pneumococcal vaccine. The total maximum time you will be on this is study is 24 months.
This is an investigational study. Both of the medications used in this study are approved by the FDA. Up to 50 patients may be treated on this study. All will be enrolled at M.D. Anderson.

|Official Title:||Immuno-Augmentation With GM-CSF in Patients Receiving Pneumococcal Vaccine While Undergoing Treatment for Advanced Chronic Lymphocytic Leukemia (CLL)|
|Study Start Date :||June 2004|
|Actual Primary Completion Date :||May 2011|
|Actual Study Completion Date :||May 2011|
Experimental: Pneumococcal Vaccine + GM-CSF
Vaccine subcutaneously + GM-CSF (3 Doses of 250 mg subcutaneously) given either Pre Vaccine at Day -7, Day -1 and Day 0 (day of pneumococcal vaccine) or Post Vaccine given at Day 0, Day +3 and Day +7.
Drug: Sargramostim (GM-CSF)
Starting with 3 doses of 250 micrograms subcutaneously, either pre or post vaccine. For pre vaccine, GM-CSF on days -7 (+ 1 day) and -3 (+ 1 day), in the week prior to vaccination for pre-vaccination immune priming; 3rd dose on the day of vaccination (day 0); and for post-vaccine GM-CSF given simultaneously on day of vaccination (day 0) and 2 more doses Day +3 and Day +7 after pneumococcal vaccine.
Experimental: Pneumococcal Vaccine Alone
First vaccine dose subcutaneously, Day 0.
Biological: Pneumococcal Vaccine
Subcutaneously on Day 0
Other Name: Prevnar
- Number of Participants (With Increase) Immune Response to GM-CSF With a Pneumococcal Vaccine [ Time Frame: Baseline and at 1 month after vaccine. ]Response defined as 2-fold rise in anticapsular immunoglobulin G (IgG) when prevaccination titer is compared with levels post vaccination and with a final level of >0.5 ug/mL. Anti-pneumococcal immunoglobulin titers measured at baseline and 1 month after vaccine. Response determined by measuring serum IgG to capsular polysaccharides from 6 of the most common infecting serotypes of Streptococcus pneumoniae.
